2023 Toyota Tundra Transmission Problems

Your truck has shut down completely while you were driving it, and this has happened at least 3 times. When the shop scanned it, they found multiple error codes related to the engine, electrical system, and fuel system. Despite several repair attempts, Toyota hasn't been able to fix the problem, and you're concerned this is a safety defect they're not addressing.

Your 2023 Toyota Tundra TRD Pro Hybrid developed a knocking noise and then the engine stopped working completely at 72,241 miles. When taken to the dealership, technicians found the engine is locked up with metal shavings in the oil, meaning the engine cannot turn over at all. The engine will likely need to be replaced or rebuilt, which is a major repair.

Your engine started knocking and lost all power, forcing you to pull over immediately to prevent a potential accident. This sudden loss of engine performance is a serious drivability issue that needs immediate attention. The repair will likely involve a thorough engine diagnostic to identify the cause of the knock and power loss, which could range from ignition timing problems to internal engine damage.

Your 2023 Tundra experienced a sudden complete loss of engine power while driving on the highway at speed, forcing you to safely exit traffic. The vehicle was taken to a Toyota dealership where technicians determined the engine needed complete replacement. Even after the repair, you're concerned about highway safety because the original failure occurred without warning.

Your 2023 Tundra has experienced repeated engine stalling and complete vehicle lockup while driving, including in traffic, which caused the driver to lurch forward into the steering wheel. Toyota replaced the neutral/park safety switch, but the problem returned immediately after the repair. The vehicle is no longer safe to drive due to this recurring issue.

While driving normally, your 2023 Toyota Tundra Hybrid suddenly lost power and entered limp mode, limiting speed to 5-10 mph without warning—creating a traffic safety hazard. Multiple warning lights appeared (Hybrid System Malfunction, Check Engine, Smart Stop System Malfunction, and Advanced Ultrasonic Detection Malfunction), and the hybrid system effectively shut down. The dealership only performed software updates and code clearing rather than thorough mechanical diagnostics, and Toyota declined further investigation. The fix would likely involve comprehensive hybrid system diagnostics, potential engine component inspection or replacement, and hybrid ECU recalibration.

Your truck occasionally hesitates when you accelerate from a complete stop, then suddenly lurches forward with excessive power. This unpredictable lag happens about 30% of the time and can cause you to accidentally pull into traffic or lose control due to wheel spin. The issue occurs without any warning lights or symptoms beforehand. A mechanic will need to diagnose the transmission or engine control system to identify what's causing the delayed response.

Your truck's gas pedal response is delayed and unpredictable—sometimes taking 3-5 seconds to accelerate, while other times the tires chirp unexpectedly. The vehicle occasionally hesitates so long that you've nearly been hit by cross traffic and held up other drivers, even when there's nothing in front of you. This delayed acceleration makes it difficult to safely maneuver away from oncoming traffic. The issue may involve the engine's throttle control system or the forward collision avoidance system interfering with acceleration.

Your 2023 Tundra has an open safety recall for the engine potentially stopping while driving. You're experiencing rough idle, shaking, and throttle lag when starting to drive, making the vehicle feel unsafe. Your dealer said they'll call when a fix is available, but nearly a year has passed without resolution. The engine control system may need to be reprogrammed or serviced once the recall remedy becomes available.

Your engine locked up suddenly, similar to a known recall issue, even though Toyota initially said your truck wasn't affected. Instead of replacing the entire engine block like other affected trucks, Toyota replaced only a short block, which concerns you because metal debris may remain in the turbo lines and could cause future turbo or engine failure. Additionally, your truck lurches and the gas pedal sometimes doesn't respond immediately. A complete turbo system flush and fuel system cleaning may be needed to remove residual metal debris and prevent future engine failure.

The engine began to misfire and stumble while idling. There was smoke present from the tail pipe when you would take off from the stop light. After Toyota ran an oil consumption campaign they came to the conclusion that the valve guides were bad and they need to replace both heads on the vehicle.

Consistently this vehicle experiences a hesitation to accelerate from a stop or rolling stop such as a stop sign or at a round about type intersection. When this occurs there may be up to a 2 second delay from when I press the accelerator to when the vehicle moves and once it does begin to move it will jump forward rapidly.

Your truck is shutting off while you're driving on the highway. You have video evidence of this happening, and your truck exhibits the same symptoms as a recent Toyota recall, even though your vehicle's manufacturing date falls outside the recalled period.

While driving on the highway, your truck suddenly lost power without warning, forcing you to cross multiple lanes to reach an exit while the vehicle continued slowing down. The dealership found engine misfires during inspection but couldn't reproduce the issue, and you also saw "Reduced Engine Power" and "Brake System Malfunction" warning lights. The dealer said they need the problem to happen again or evidence of a failure before they can pursue a repair or involve Toyota. Addressing this will likely require diagnosing the engine misfires, checking fuel delivery and ignition systems, and investigating the brake system warning.

Your engine shut down suddenly while driving at highway speed (70-75 mph), forcing you to coast to the shoulder. When you tried to restart, you heard only clicking sounds from the starter and noticed a faint burning smell from the engine compartment. A Toyota dealership found metal shavings inside the engine, indicating internal damage that requires a complete engine replacement.

Your truck was sold while already under recall for a fuel tank issue over a year ago, but dealers still don't have enough parts to fix it. Two additional recalls have been issued since then with no timeline for repair. Your truck has been unsafe and unfixable for an extended period despite multiple recalls.

You witnessed another vehicle suddenly shift from Drive to Reverse and then to Park while moving on the highway, causing it to brake hard and leading to a collision. The other driver's wife had been touching the shift lever, but the concern is whether the electronic shift control malfunctioned or if there's a design flaw that allows gear changes while the vehicle is in motion without mechanical safety locks. The issue may involve a failed circuit board, defective control module, or similar electronic transmission control problems.

Your Tundra hesitates when you accelerate from a stop, delaying the engine's response to your gas pedal input. This unpredictable delay makes it difficult to safely merge into traffic since you can't reliably predict how quickly the truck will accelerate. The issue appears to involve the fuel system or engine throttle response and may require diagnostics at a dealership.

Your truck hesitates for 1-2 seconds when you accelerate from a stop or slow speed, which has created dangerous situations when merging into traffic. This delay in power delivery is a significant safety concern that needs diagnosis. The fix will likely involve checking your transmission fluid, fuel system components, or having the engine computer scanned for fault codes.

Your truck got stuck in 4-wheel drive mode with the 4-low light blinking, and you couldn't shift out of it. A technician had to recalibrate a sensor to restore normal operation.

Your truck sometimes hesitates for 1-2 seconds when you try to accelerate from a stop, then suddenly lurches forward with a burst of power. This unpredictable response has happened multiple times, particularly when entering busy intersections, creating a safety concern. The issue appears to be related to how the fuel system or transmission responds to your throttle input. Diagnosing this will likely require a fuel system inspection, transmission fluid check, and engine computer diagnostic scan.

Your engine occasionally stalls or stutters when you release the brake and press the gas pedal at a stop sign or red light, causing your truck to either hesitate before moving forward or not respond at all. This has happened 6-7 times since January 2024, and it's been dangerous—including once when your truck stalled while you were crossing a divided highway. The fix will likely involve diagnosing the fuel delivery system, ignition timing, or engine control computer to identify why the engine is cutting out during acceleration from a stop.

Your truck has a noticeable delay between pressing the gas pedal and the engine responding, especially when starting from a stop at traffic lights or signs. This delay sometimes causes the vehicle to jolt forward suddenly, which has nearly caused accidents. The issue likely involves the throttle control system or fuel delivery timing and may require diagnostic testing and software updates or throttle body service.

Your truck experiences a 2-4 second delay in acceleration when you first start driving in cold conditions, followed by a sudden jolt forward. This hesitation when merging into traffic creates a safety concern. The issue disappears once the engine warms up, making it difficult for dealers to diagnose and repair.

Your truck's throttle response is slow and sluggish, especially at low speeds, and you're experiencing jerky acceleration. This could indicate an issue with how your engine responds to the gas pedal or your electrical system controlling the throttle.

Your 2023 Tundra hesitates or fails to accelerate smoothly when you press the gas pedal, whether you're stopped at a light or driving at various speeds. No warning lights appear on your dashboard. The dealer reset your transmission software, but the problem came back. A previous dealer performed an engine recall on your vehicle, but the hesitation issue persists. The problem started around 40,000 miles. Fixing this may require a deeper transmission software update, fuel system inspection, or engine diagnostic work beyond a simple reset.

Your truck hesitates and responds slowly when you press the gas pedal while rolling to a stop, creating a delayed acceleration. This sluggish response time could increase the risk of a crash or injury if you need to accelerate quickly in traffic or at an intersection. The issue appears to be coming from the engine or powertrain. A mechanic will likely need to diagnose the engine's fuel delivery and ignition timing systems to identify the cause.

Your truck stalls for 1-2 seconds when you accelerate after slowing down or stopping on an incline, then suddenly lurches forward. This hesitation has created dangerous situations where you're stuck in traffic unable to complete turns or safely cross lanes. The dealership is aware of the issue but hasn't been able to reproduce it to diagnose the cause. A technician will likely need to perform engine diagnostics and may check fuel delivery, transmission programming, or engine control module software.

When you accelerate from a stop or low speed (under 15 mph), your engine has a noticeable delay before responding to the gas pedal. This throttle lag makes it difficult to merge or enter traffic safely, creating a potential accident risk.

Your truck hesitates or delays when you try to accelerate from a stop, which has almost caused you to be in crashes when turning left because the engine doesn't respond for a few seconds. This throttle lag makes it difficult to merge or turn safely in traffic. The issue likely involves the fuel delivery or engine control system and may require diagnostic testing and possible repairs to the fuel injectors or engine computer.

Your truck sometimes hesitates or lags when you accelerate after coming to a stop, which can create a safety concern. The engine may not respond immediately when you press the gas pedal. This could be caused by issues with the fuel delivery system, engine sensors, or transmission programming, and may require diagnostic testing and potential repairs to those systems.

Your truck sometimes hesitates when you press the accelerator after coming to a brief stop. Instead of responding immediately, there's a 1-2 second delay before the engine accelerates, which has created dangerous situations when crossing traffic. This delayed response could be caused by issues with the fuel system, engine sensors, or transmission programming, and will likely require diagnostic testing to identify and repair the underlying problem.

Your 2023 Tundra sometimes hesitates or lags when you press the gas pedal from a complete stop, causing the truck to respond slowly or not at all. This happens unpredictably without warning lights and can be dangerous when turning across traffic or merging, as your truck may not accelerate when you need it to. A dealer hasn't yet confirmed the issue, but it's happened multiple times during normal driving. The fix will likely involve inspecting and possibly replacing throttle body components, fuel injectors, or reprogramming the engine control system.

Your truck hesitates for a brief moment when accelerating from a stop or while driving, then jolts forward suddenly. This also happens when you shift into gear. The dealership says this is normal, but you're concerned because your truck sometimes stalls when you press the gas pedal, which feels like a safety risk. The issue may involve fuel delivery, engine response, or transmission shift timing and should be diagnosed by checking fuel pressure, spark plug performance, and transmission control settings.

Your truck occasionally loses power and hesitates during acceleration, particularly when starting from a stop, which can make it unsafe to pull into traffic since you can't predict when it will happen. This hesitation can leave you too close to other vehicles in dangerous situations. The issue may involve fuel delivery, ignition timing, or engine sensor problems that need diagnostic testing.

Your truck hesitates or feels sluggish when you first accelerate from a stop, and the same thing happens when going uphill—if you ease off the gas and then press it again, the engine doesn't respond right away and the truck rolls backward before it catches up. This has made the truck unpredictable to drive, especially in hills.

Your truck hesitates and lags when accelerating from a stop, especially while turning, then suddenly catches and accelerates rapidly. This unpredictable acceleration makes it dangerous when crossing traffic, as other drivers can't anticipate your vehicle's speed and may hit you from the side or rear. You've reported this to your dealer, but they couldn't reproduce the problem, and no warning lights appeared on your dashboard.

Your truck loses significant power when accelerating from a stop and makes a ticking sound from the engine. Additionally, your fuel gauge shows a full tank when you actually have about half a tank. These issues may involve fuel system diagnostics, engine knock detection, and fuel gauge sensor inspection.

Your truck hesitates when you first accelerate—both when starting in the morning and at stop signs—before suddenly jumping forward with a jolt. This delayed response followed by sudden acceleration has nearly caused you to rear-end other vehicles. The issue likely involves the engine's fuel delivery or throttle response system needing diagnosis and adjustment.

After you brake or stop at a stop sign, your Tundra's engine hesitates for 2-3 seconds before responding when you press the accelerator, even with the pedal fully pressed. This delay is especially noticeable when turning right from a stop, making it dangerous when you need to accelerate into traffic. The transmission appears to be hunting for the right gear, getting stuck in 6th gear before downshifting abruptly to 2nd and jerking forward. The issue may involve the engine control module (ECM) not properly coordinating transmission shifts after braking.

Your truck may hesitate or sputter when you press the accelerator, then suddenly jolt forward. This hesitation happens intermittently, making acceleration feel inconsistent and unpredictable. A mechanic will likely need to diagnose the fuel system, ignition system, and engine computer to find the cause.

Your truck hesitates when you press the gas pedal from a stop, then suddenly surges forward with speed. This unpredictable behavior makes it hard to control your acceleration in traffic and could create a collision risk. The problem happens repeatedly. A mechanic will likely need to diagnose the engine's fuel delivery and ignition timing systems to find the cause.

Your transmission fluid is running hotter than it should. While normal operating temperature is between 167–185°F, your transmission is reaching over 200°F during regular driving. If this continues during towing, long trips, or stop-and-go traffic, your transmission could overheat and fail, leaving you stranded in traffic with a vehicle too heavy to safely move. This may require the transmission cooling system to be inspected and repaired.

Your truck stalls or stutters for a few seconds when accelerating from a stop, especially when the engine is cold or after you've slowed down. This problem continues even after the recall and transmission control module reprogramming. The truck eventually accelerates normally, but the hesitation occurs repeatedly.

Your truck hesitates and feels like it might stall when you accelerate from a stop, and it doesn't respond smoothly to throttle inputs. This creates a safety concern since you may not be able to accelerate quickly to avoid an accident. The issue likely involves the engine's fuel delivery or ignition timing system, which may need diagnostic testing and adjustment or component replacement.

Your truck is experiencing excessive hesitation when accelerating from a stop or during slow starts, with the engine sometimes taking several seconds to respond to throttle input. No warning lights appear, and this issue occurs randomly despite the truck having fewer than 18,000 miles. This delayed acceleration creates a safety concern when merging into traffic or trying to avoid obstacles.

Your transmission isn't downshifting properly when you're driving slowly in stop-and-go traffic (under 5 mph), which causes a noticeable delay of a couple seconds before the vehicle accelerates when you need it to. This lag happens repeatedly at low speeds and can create a safety concern in intersections or heavy traffic when quick acceleration is necessary. The transmission seems to require a complete stop and pause to downshift correctly, which isn't practical in real-world driving conditions. A transmission software update or transmission fluid service may be needed to address the downshift response timing.

Your truck sometimes hesitates for up to two seconds when you press the accelerator from a complete stop or while rolling slowly, then suddenly surges forward with rapid acceleration. This delay and surge feels unsafe when merging into traffic, though it typically returns to normal within seconds. The problem happens unpredictably and seems more likely after a cold start, but your dealer hasn't been able to fix it despite multiple service attempts and a technical service bulletin.

Your truck's transmission is shifting with harsh, hard kicks at all speeds. When you engaged 4WD, the engine shut off unexpectedly, and after restarting you noticed a burned transmission fluid smell. This issue occurred previously at 1,400 miles when the dealership cleared diagnostic codes without resolving the underlying problem. The transmission may need inspection, fluid replacement, or repair to address the shifting and overheating issues.

Your truck experiences a noticeable delay when accelerating from a stop, making it difficult to merge onto highways safely and putting you at risk of being hit by other traffic. You've reported this to the dealer multiple times, but they've dismissed it as normal behavior for the V6 engine. This delay could potentially cause accidents if not properly addressed. Diagnosis would likely involve checking the transmission's shift response, fuel delivery system, and engine control computer settings.

When you accelerate from a stop or near-stop (like at a stop sign), your engine hesitates and doesn't respond right away to the gas pedal, then suddenly lurches forward. This happens multiple times, especially when the engine is cold in the morning, and has gotten worse since September 2023—sometimes leaving you stuck in an intersection. The dealer has checked it five times without finding a fix, though a Toyota corporate representative confirmed experiencing the hesitation and sent data to engineering. A software update or engine control module reprogramming may be needed to address the delayed throttle response.

Your engine is running roughly at idle and occasionally misfiring, which the dealership claims is normal. Your truck has also completely shut off while using 4WD, leaving you stranded. The dealership cleared the error codes but didn't perform any actual repairs, and you're concerned because multiple recalls on your vehicle don't have available solutions yet.

Your infotainment system keeps asking for a PIN every 1-2 minutes, even after multiple resets and dealership visits — forcing you to enter a 6-digit code repeatedly while driving, which is dangerous. Your brakes started squealing at 4,000 miles and are getting progressively worse despite cleaning, making it difficult to know when they actually need replacement. Additionally, your truck jerked forward violently while stopped at a red light with the brake pedal fully pressed, which could indicate a brake system malfunction. These issues will likely require software updates to the infotainment system, brake pad inspection or replacement, and a full brake system diagnostic to rule out hydraulic or electronic brake problems.

Your truck hesitates or delays when accelerating from a stop, and sometimes feels like it's in too high a gear when starting from low speeds (3-5 mph), making it sluggish and harder to control in traffic. You may also notice harsh or jerky shifts in the lower gears. The dealer says your transmission software is fully updated, but these problems have been there since you bought the truck. A transmission specialist may need to diagnose whether a software recalibration, transmission fluid service, or internal transmission repair is needed.

Your Tundra is rolling forward on a level driveway even when the transmission is in Neutral, which shouldn't happen. You noticed this when the truck started moving forward while you were trying to get out of it on a flat surface. This is a significant safety concern because the vehicle should not move on level ground without the engine engaged.

Your truck needed replacement of the driveshaft, rear differential, and transfer case before 1,200 miles due to faulty factory parts. The dealership initially dismissed your concerns and blamed noisy rear brakes instead of investigating the drivetrain problem. Your vehicle ultimately required a full rebuild using genuine Toyota parts to resolve the issue.

Your truck started making loud clunking sounds from the rear at around 500 miles, especially at low speeds, and the noise got progressively worse. The dealership initially thought it was worn brake rotors and replaced them, but the real problem turned out to be a damaged driveshaft and a rear differential that was beyond repair. Fixing this will likely involve replacing both the driveshaft and rear differential assembly.

Your truck experiences a delay when you press the accelerator from a complete stop—it takes about 1.5 seconds to respond, then lurches forward as if struggling to engage the transmission. This happens repeatedly at stoplights and stop signs. The issue likely involves the transmission control system or throttle response calibration.

Your truck hesitates and delays when you press the gas pedal, especially when starting from a stop at lights or stop signs. The dealership reprogrammed your transmission software, which briefly fixed it, but the problem came back quickly. No warning lights appear, and other owners report the same issue without a permanent fix found yet. This may require a transmission software update or investigation into the fuel and ignition timing system.

Your truck's throttle sometimes lags or hesitates when you accelerate from a stop, causing a delay in response. This creates an uneven driving experience during initial acceleration. The issue may involve checking your throttle response system, fuel delivery, or engine control settings.

Your truck hesitates when you accelerate from a stop. When you press the gas pedal at a stop sign, there's a noticeable delay before the engine responds normally. This could involve checking your fuel system, ignition system, or engine sensors to identify what's causing the delay.

Your truck occasionally hesitates or responds slowly when you press the gas pedal to accelerate from a stop, especially right after starting the engine. This happens infrequently but can make the truck feel sluggish during initial acceleration. The issue may involve cleaning or replacing fuel system components or having the engine control system diagnosed.

There is a lag in the accelerator. It happens 10 to 20% of the time. It is a one or two second lag on the gas pedal.

When you press the gas pedal from a complete stop, your truck hesitates for a couple of seconds before accelerating normally. This delay happens consistently when starting from a stopped position.

The contact owns a 2023 Toyota Tundra. The contact stated while driving out of the driveway, the contact shifted into neutral the vehicle started rolling forward. The contact was able to stop the vehicle.

Your truck hesitates when you press the gas pedal from a stop, taking more than 2 seconds before it accelerates. This delay makes the vehicle feel sluggish during normal driving and when merging into traffic. The issue is related to how the engine responds to throttle input. Diagnosis may involve checking the fuel system, throttle body, or engine control software.

I continue to get this message on my dash while driving and no one in front, on side or behind my vehicle: *Foreign Object Speed Acceleration reduced. *Radio Know broke a second time *windows stutter when going up or down while wet *windows rattle *poor acceleration at take off ( very dangerous on the expressway)
