While driving, my Chevrolet Tahoe suddenly developed a severe, rhythmic bottom-end engine knock, indicating a catastrophic internal mechanical failure. I immediately took the vehicle to an authorized Chevrolet dealership on May 29, 2026, for emergency diagnosis.The dealership technicians officially diagnosed the issue as a severe lower-end engine failure. They deemed the engine unrepairable and determined that a complete long-block engine replacement is required.As of today, July 6, 2026, the vehicle has been sitting at the dealership for over 5 weeks and has yet to be fixed. The prolonged delay and sudden mechanical failure present a severe safety hazard, leaving me without a vehicle due to known GM manufacturing defects currently under NHTSA investigation. This report is being filed to document the failure of the 6.2L engine lower end, the necessity of a full long-block replacement, and the ongoing repair delay.

Vehicle: 2024 Chevrolet Tahoe RST The backup camera and HD Surround Vision system on my 2024 Chevrolet Tahoe have experienced repeated failures despite multiple repair attempts by an authorized Chevrolet dealership. The failure presents as a black screen displaying a red warning triangle and a crossed-out camera icon when the vehicle is placed in reverse or when camera views are selected. The parking sensors continue to function, but no camera image is available. The vehicle was first repaired in July 2025 (6705 miles) after the dealership diagnosed heat damage to the rear camera coaxial cable located in the liftgate area. The cable was replaced, and the vehicle was returned to service. The camera system failed again the same day. The vehicle was subsequently returned to the dealership, where the liftgate harness was replaced in Aug 2025. Following the repair, the camera system operated normally for a period of time before the same failure condition returned. At approximately 16,500 miles (May 2026), the backup camera and HD Surround Vision system have again become inoperative. This represents at least the third occurrence of the same issue despite prior repairs involving replacement of camera-related wiring components. The loss of the backup camera and surround vision system significantly reduces rearward visibility while backing, parking, and maneuvering the vehicle. Because the condition is intermittent and recurring, the driver cannot reliably depend on the camera system to function when needed. I am submitting this complaint because the issue has recurred multiple times after repair attempts and may indicate a broader defect affecting the vehicle's camera system.

My vehicle started having stuttering/shifting issues back in August 2025, I was advised the vehicle did not need new engine but upgraded oil. I continued to have the issues and have continued to bring back to dealer for constant software updates - cannot duplicate issue meanwhile the stop sale order was issued and I was not advised. The vehicle then experienced very hard jerking- stall- that lead to the dealership putting an AWD IN 2WD calling it a fix! Just got vehicle back again after a complete stall at a stop sign- causing vehicle to roll back and cut back on! Dealer stated the vehicle showed the stall/shutter but could not duplicate on road test. This is a serious safety issue!!

On Saturday, April 25, 2026, I experienced engine failure on my 2024 Chevrolet Tahoe 6.2L V8. This was a very dangerous situation, and could of been potentially dangerous to others around me on the highway. There was no warning just complete loss of engine propulsion at highway speeds. It was towed to the dealership on this same date. On Monday, April 27, 2026, it was confirmed by the Chevrolet Dealership that this vehicle suffered catastrophic engine failure and that the engine was seized up. Inspection would be available upon request.
