The transmission failed at 100,000 miles and the engine failed at 130,000 miles. Available for inspection. Yes the dealer confirmed both failures. No warnings. Immediate failure with engine light. Barely made it home with the transmission and the engine just stopped out of nowhere due to the dynamic fuel management system and oil consumption starvation.

One day when headed out of town I stopped and got gas immediately once getting back on the highway my dash lit up like a Christmas tree, driving became uncomfortable as it sputtered when trying to give gas. I looked up a couple of the dash warning lights and it alluded to emission problems. I take the truck to the mechanic and he says that a head is cracked and the cam shaft needs to be repaired. This issue came out of nowhere, no prior issues as far as over heating or any dash lights on.

Component/System Failure and Availability for Inspection: While driving at 70 miles per hour on the interstate, the vehicle suffered a complete loss of oil pressure. The engine warning light illuminated, and the vehicle simultaneously stopped operating. The vehicle and its components are available for inspection upon request. Safety Risk: This failure posed a severe risk to my safety and the safety of others. The sudden and complete loss of engine function at highway speed could easily have resulted in a serious accident. I was fortunate the incident occurred in an area that was not heavily populated at the time. Under different circumstances, this failure could have led to life-threatening consequences. Reproduction/Confirmation of the Problem: The issue has not yet been reproduced or confirmed by a dealer or independent service center, but the nature of the failure was sudden, significant, and left the vehicle inoperable. Inspection by Others: The vehicle has not yet been inspected by the manufacturer, police, or insurance representatives, but it remains available for review. Warning Lamps/Messages/Symptoms: The only indicator prior to the failure was the immediate illumination of the engine light as the oil pressure dropped. This warning appeared at the same moment the vehicle lost power and stopped operating, leaving no opportunity to respond before the vehicle was disabled. Numerous comments and complaints with the same issue. Cust Satisfaction N212326940, does it take someone getting injured or dying before this administration makes the compnay do the right thing?

While driving "No Oil pressure" alarm went off on my 2019 Chevrolet Silverado. I had to immediately pull off to the side of the road, upon inspection the Oil cooler line separated at the crimp joint. This is the exact failure mode as described in "N212326940 - Customer Satisfaction Engine Oil Cooler Lines Detaching from Crimp". I have my truck at a GM dealership and they said my VIN is not included on the TSB. I also contacted GM Customer Service and was told the same that my VIN was not effected by this issue. My failure is the same mode as the documented issue, it has to be related to part quality issue as described on N212326940. The GM dealership is charging me $2000 to replace the line.

On 7/2/25, I was driving my 2019 Chevy Silverado on the highway and felt like there was a slight loss of power. I then noticed the Service parking brake, service ESC and the check engine light came on. I was going up a hill and had to move over to the far right lane and drive very slowly on the highway because of the engine problem. I was able to get off the highway without incident. I immediately took the truck to the Chevrolet dealer where I purchased it since it was very close. The dealership later inspected the truck and found the lifters had seized and caused damage to the camshaft. They said I would need a new engine at a cost of around $15,000. There were no warning signs or problems to indicate I was going to have an engine failure. The instrument warning lights came on when the engine problem occurred.
