2025 Toyota Tundra Cruise Control Problems

Your Tundra is stalling or hesitating when you accelerate, which has created unsafe driving situations. This problem happens frequently and started when you first purchased the vehicle. The issue likely involves the fuel delivery or engine control system and may require diagnostic testing and repairs to the fuel injectors, fuel pump, or engine computer.

Your truck experiences a significant delay when you press the throttle, and the engine stalls when starting from a stop, which creates a safety hazard. The complaint also mentions engine failures occurring without the hybrid system's assistance, leaving the vehicle unable to reach a safe location if a problem occurs. According to the owner, Toyota is replacing failed engines, but the replacement engines are experiencing the same failures.

Your truck's accelerator became unresponsive when you tried to accelerate from a stop at an intersection, causing it to drift slowly at only 5 mph with no engine power despite pressing the gas pedal firmly. The accelerator eventually responded but lagged again when you tried to accelerate quickly to clear the intersection, nearly resulting in a collision with oncoming traffic. This happened at least twice, no warning lights appeared, and the issue hasn't been serviced by the dealer.

When you started your 2025 Tundra on 8/6/2025, multiple warning lights appeared on the dashboard reporting problems with the advanced radar system, pre-collision safety system, parking brake, engine computer, stability control, and secondary collision braking. Your truck is also accelerating very slowly — it takes almost a mile to reach 45 mph on flat ground, even though it worked fine the day before. The underlying issue is likely a serious engine computer malfunction that's triggering all these related warnings, which will require professional diagnostic scanning and ECM repair or reprogramming.

Your truck's throttle response is delayed and inconsistent. When you pressed the gas pedal at a stop sign, the truck accelerated normally at first, then suddenly stopped accelerating completely before lurching forward again—creating a dangerous situation with oncoming traffic. This delay in throttle response could cause safety issues in traffic situations where quick acceleration is needed.

Your truck hesitates and delays for several seconds when you try to accelerate from a stop or during slow-speed driving, whether going straight or turning. This sluggish acceleration response could put you in danger, especially when turning across traffic where you need quick power to avoid oncoming vehicles. The issue appears to be a delay in the engine or fuel system responding to your acceleration commands, and may require diagnostic testing and repairs to the fuel delivery or engine control systems.

Your speedometer is reading 9 mph slower than your actual speed (showing 55 mph when you're actually going 64 mph), making it easy to accidentally exceed speed limits and increasing accident risk. This inaccuracy also affects your odometer's mileage tracking, which could cause you to miss important maintenance like oil changes and tire rotations. The fix will likely involve recalibrating or replacing the speedometer module and associated sensors.

Your truck experiences intermittent hesitation when accelerating from a stop, with a 1-2 second delay before the engine responds to throttle input. This lag occurs randomly and has created dangerous situations when merging into fast-moving traffic, forcing you to brake hard to avoid collisions. The problem is difficult to reproduce and hasn't triggered any warning lights. The fix may involve diagnosing the throttle control system, fuel delivery, or engine management computer to identify where the delay is occurring.

Your truck hesitates for 1-2 seconds when you press the gas pedal from a complete stop, creating a dangerous delay in acceleration. This has happened twice within the first 600 miles of ownership. The delay could make merging or crossing traffic risky.

Your truck occasionally hesitates when you try to accelerate. This intermittent issue could indicate a problem with the engine's fuel or ignition system. A mechanic will need to diagnose the root cause, which might involve checking fuel injectors, spark plugs, or the engine control computer.

On several occasions when attempting to accelerate from a complete stop, the vehicle fails to accelerate, or begins to accelerate and then ceases, leaving the vehicle partially out into incoming cross traffic. This occurs for a second or two before acceleration resumes.

There is significant throttle lag where the throttle has a delay in engagement after a rolling stop. Turning into traffic flat out is dangerous when the throttle has a delay, if you push harder then it gives you too much throttle after the delay and will chirp the tires. I am not the only one.
