2023 Chevrolet Tahoe — Known Issues & Recalls

Your engine failed completely and required replacement with a new engine. The exact cause and circumstances aren't detailed in this report, but this represents a total engine failure rather than a repair of individual components.

Your engine suddenly failed and stopped working while you were driving, causing a loss of power. This happened even though the dealership recently inspected your 6.2L engine as part of a recall for this exact issue and told you it passed their test. The engine needs to be diagnosed and likely replaced to restore your vehicle's operation.

Your engine has completely failed and will not run. This is a critical powertrain problem that requires immediate professional diagnosis and repair. The engine may need to be rebuilt or replaced entirely.

Your engine shuts off suddenly without any warning lights or symptoms beforehand, and this has happened at various mileage intervals. In your case, the engine cut out while you were passing on the highway. The issue likely involves diagnosing the ignition system, fuel delivery, or engine control module to identify why power is being lost unexpectedly.

Your engine shut down without warning while driving through an intersection, and the vehicle wouldn't restart. A low engine oil warning light appeared on the dashboard, and the car was stuck in gear—you couldn't shift it to neutral for towing. The dealership confirmed the engine had failed. This requires a full engine diagnosis and likely replacement or major repair.

Your replacement engine is consuming oil at an unusually high rate and experiencing intermittent lag or hesitation while running. You're waiting for a diagnostic appointment with Chevrolet to identify the root cause. The issue may involve internal engine wear, a faulty oil seal, or a sensor malfunction that needs to be inspected and repaired.

While driving at 70 MPH, your vehicle suddenly lost power and the check engine and oil pressure warning lights came on. The engine unintendedly slowed down, and you saw a "Press START Button" message on the dashboard; restarting the vehicle temporarily fixed the problem. Your mechanic found that the transmission had shifted itself from Neutral to Park, and suspected low oil consumption, but couldn't identify the root cause. The issue may require an oil consumption test and further engine diagnostics to determine what's causing the power loss.

After having your 2023 Chevrolet Tahoe serviced at a dealer, an "Add Oil" warning appeared on the dashboard and your vehicle began consuming oil excessively. The root cause hasn't been identified yet, and the manufacturer hasn't offered assistance. This occurred at 18,000 miles.

Your transmission unexpectedly downshifted while driving 50 MPH, causing the engine to seize and the vehicle to become unresponsive. The check engine light came on and a reverse indicator flashed, and you couldn't restart the vehicle initially. After restarting, the problem happened again, and your car struggled to accelerate or shift into reverse. The vehicle was towed to the dealer but remains unrepaired. This issue likely requires transmission diagnostics and possible internal transmission repair or replacement.

After your 2023 Chevrolet Tahoe was serviced under a recall in November 2025 that included an oil change with higher viscosity oil, your engine lost power while driving at 55 MPH and the transmission shifted to neutral on its own. When you tried to shift back to drive, the engine stalled and wouldn't restart. The dealer found that your engine, starter, radiator, and fuse block all need to be replaced.

While merging onto a freeway at 65 mph, your engine's RPM spiked and power dropped without warning lights. Minutes later, your check engine light came on with warnings about hot oil and low oil pressure, and your engine shut down completely at 15 mph. The engine would not restart consistently and kept turning off and on. Your dealer confirmed you need a complete engine replacement due to a defect.

Your 2023 Tahoe has experienced multiple system failures at startup on several occasions, where your brakes become unresponsive, your steering wheel locks up, and you lose vehicle control—creating a serious safety hazard. When this happens, your dashboard displays warnings including "Brake system failure" (limiting you to 43 mph), forward collision system unavailable, and multiple service alerts for traction control, electronic stability control, steering column lock, and brake pad monitor. Your dealership has replaced several modules and your battery multiple times, and even performed a recall software update, but the problem keeps recurring.

Your 2023 Chevrolet Tahoe experienced a brake failure while driving at 35-39 mph, forcing you to coast uphill and apply maximum pedal pressure to slow down to 5-7 mph before stopping. You've also had multiple incidents where the vehicle became stuck in Park with dash warning lights illuminated (including brake failure and Forward Collision System Unavailable warnings), and one incident required towing. Despite dealer visits and manufacturer involvement, the problem has recurred, suggesting the underlying issue may not have been fully resolved. The fix will likely require a complete diagnostic inspection of the brake system, electrical system, and transmission shift mechanism to identify and repair the root cause.

Your 2023 Tahoe has a faulty telematics communications module that's preventing the OnStar system from working and your myChevrolet app from syncing to your account. This module failure is also causing your clock to run slow, suggesting battery drain. The bigger concern is that the previous owner's account is still linked to the vehicle, potentially allowing them remote access to start your car, unlock doors, and track your location — even while it's in your garage. The dealership sold you the vehicle without fixing this known defect and refuses to repair it now. The fix will require the telematics module to be replaced and the vehicle to be properly registered under your account with OnStar.

Your dashboard warning lights all turned on when you started your car, and your brakes completely failed when you tried to stop in reverse — you could only slowly back into your driveway. The next day your brakes worked again and a check engine light appeared, but it went away after that. This is happening on a nearly new car with only 8,500 miles, and you've heard of at least one other 2023 Suburban owner experiencing the identical issue, which raises serious safety concerns. A dealership technician will need to diagnose and repair the brake system electrical connection and check engine computer codes.

Your brakes failed while driving downhill, preventing you from stopping your car — a critical safety situation. Multiple warning lights appeared on your dashboard: service brake pads, forward collision system unavailable, brake system failure, service traction control, service ESC, and check engine light. This is the second occurrence in four weeks, even though the vehicle was recently repaired for this issue.

Your Tahoe won't start using the keyless remote when the fuel tank is nearly empty. When you do get it started, all dashboard warning lights turn on, including a brake system failure warning. Most critically, your brakes become completely unresponsive (0 brake pressure), and multiple safety features like forward collision avoidance and traction control stop working. This issue has happened before and sometimes resolves on its own. The problem likely involves the vehicle's electrical system and brake control module, which may need diagnostic testing and possible replacement or reprogramming.

Your 2023 Tahoe's engine seized on the highway in November after a recall service, forcing a complete engine replacement. Since getting the new engine installed, you're experiencing hesitation during acceleration, stalling when slowing down, a flashing check engine light at highway speeds, and your instrument cluster randomly going dark. The dealership has cleared diagnostic codes but hasn't resolved the underlying issues. The fix will likely require detailed engine diagnostics and possibly another engine replacement or repair of fuel and ignition system components.

Your 2023 Tahoe's steering wheel pulls to one side while driving straight, requiring you to constantly correct the steering to stay in your lane. Even though no warning lights appeared, this misalignment creates a safety concern because it affects how the vehicle tracks and handles on the road. The steering components were inspected and replaced by the dealer, but the issue required multiple service visits. The fix likely involves realigning the steering system and checking suspension components that affect wheel alignment.

Your 2023 Chevrolet Tahoe's factory-installed running boards become dangerously slippery during light snow or winter rain, making it easy to slip while getting in or out of the vehicle. You may experience near-falls even when stepping carefully, and the problem happens repeatedly during normal winter driving conditions. This is particularly concerning if children, elderly passengers, or people with mobility issues use the vehicle. The issue may be addressed through improved running board surface material or a protective coating to increase traction in wet winter conditions.
