Engine locked up from crankshaft bearing failure, mega fuse blown My wife and I were driving 70mph on a highway when I lost the throttle and other power. I pulled over to the side the best I could but barely over the white line. It was a dangerous situation for us & tow trucks, the engine was locked up & the flat bed truck couldn't tow vehicle. The 2nd truck was a reaper style truck which was dangerous to setup on the side of highway. The dealership diagnosed and replaced engine to their guidelines. I requested the oil cooling lines & housing be replaced as well to avoid metal debris to enter new engine to avoid recurring engine failure. At first both requests were denied, then another dealer represntive said the oil lines would be replaced but the housing would not be. I even offered to pay for that replacement which was denied. I invested a lot into the vehicle, I was assured the original recall and engine oil change would be sufficient. I also purchased to dealer premium care package to really take care of my vehicle investment.Engine failure was around 29,000 miles. The engine failure happened on a Sunday morning, I didn't receive any loaner car or rental car until Thursday affecting my work transportation. Once the dealer rented me a car, I asked if I needed anything to pick up the car, dealer rep said no. Once at rental car place, I needed a credit card and ID, I was charged $250 for the time I had the rental car. The rental car was not close or comparable to my vehicle, which I still had to make payments while it was broken at the dealership. I really worry about my safety, reliability and travel going forward with this vehicle. I also am very concerned about the vehicle losing value due to known issues. There was no warning signs until the failure, I believe the dash message said 'please press start' or 'press start'. Overall this has been a tough and stressful situation with my expensive vehicle investment. Vehicle unavailable- 7/26-8/17

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 the federal safety agency 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.

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!!

The vehicle in question had approximately 5000 miles when low oil light came on, it was 2 quarts low. this was after the first oil change at around 3500 miles. I had the dealer do an oil consumption evaluation. They check the oil every 500 miles and confirmed it was using 2 quarts every 2500 miles. They informed me GM says this is normal. I cannot disagree more with that claim. GM knows they have a problem with the 6.2-liter engine. I have researched the issue and found they have a problem with the crankshaft machining and the oil delivery port beveling that delivers lubrication to the connecting rod bearing appears to be too large that causes the motor oil not to consistently keep the bearing lubricated. This causes the engine to be an "oil burner" and premature failure of the bearing. They think putting a heavier viscosity of oil in will delay the inevitable engine failure, which makes me believe they are aware of the faulty manufacturing and want to run from their warranty responsibilities.

See attached document for complaint. We are writing to express our concerns regarding ongoing and unresolved issues with our 2024 Chevrolet Tahoe High Country Deluxe Package, which we purchased on [XXX] from Titus-Will Chevrolet in Olympia, Washington. Our vehicle was ordered on [XXX] and delivered with 12 miles on the odometer [XXX]. The total purchase price was $97,889.61. This vehicle is equipped with a 6.2-liter Ecotec VB engine and a 10-speed automatic transmission. Since shortly after purchase, we have experienced intermittent audio output problems. With these problems, there is no audio for the radio, phone calls or mapping directions from any of the apps. Incoming phone calls do not connect and outgoing calls cannot be made. Despite multiple service visits-[XXX] as well as documented audio output issues my wife recorded and dated due to the fact that the dealership is 50 miles away: [XXX] We have also driven our vehicle into the Titus Will dealership service department twice when the audio output was not working so the service techs were able to see exactly what was not working-the issues are still unresolved even after updates from the service department and over the air updates that were to "FIX" the issues per GMC/Chevrolet. Our dealership has been unable to identify or correct the defect. Additionally, we received a Safety Recall Notice (N252494000) on May 20, 2025, concerning a potential loss of propulsion in the 6.2-liter engine, which may lead to catastrophic engine failure and increased risk of a crash or harm. We were surprised to learn that this recall was issued on April 24, 2025-prior to our purchase date-yet was not disclosed by the dealer at the time of sale, which also appears to be deceitful on GMC's part. We would not have accepted the vehicle knowing there were catastrophic engine problems as we travel the highways often visiting family in Idaho and Spokane as well as taking care of our elderly parents this last year with their medical care transports.

Purchased new vehicle in September 2024, immediately after purchasing the vehicle the engine had a clanking noise. Took the car back to the dealership where they explained the noise was normal. The car continue to make clanking noise, but noise continued to get louder, took the vehicle back to the dealership for first oil change, verify the noise, and discuss safety recall received on the vehicle. Dealer told me the car was ok to drive. In October 2025, the vehicle loss power during acceleration with immediate re-start. After this incident, took the vehicle to another dealer where they inspected the vehicle again. The test failed and the car now needs a new engine.
