2026 Chevrolet Silverado 1500

On Monday, June 29, 2026, I was getting off the New Jersey Garden State Parkway. I was halfway down the exit ramp and the engine and the engine just stopped. I coasted to the bottom of the exit ramp and luckily had just enough shoulder to pull over to get out of traffic. Once stopped, I attempted to start my 2026 Chevy Silverado, but all attempts at starting the engine were fruitless, as the engine would not even turn over when tried. I contacted On Star and a tow truck was sent to tow my truck to Burke, the GM dealer I purchased the truck from. It was confirmed by Burke GM on Wednesday, July 1, 2026, that the truck needed the engine replaced. The truck is currently at Burke GM and I have been there to get belongings out of the truck so yes, I would say it’s safe to assume that it is available for inspection. There were no warning signs of any problem with the motor at all.

While driving my truck returning from a camping trip I received the following warnings in the dash: Service ESC, Service traction control, forward collision system unavailable. Check engine light was flashing. I made the assumption that the Check engine light was due to the warnings listed above. I continued to drive the vehicle until I began to feel a very noticeable shudder at idle, at low speeds, and also loss of power at higher speeds. The truck has the 5.3 ecotec engine with DFM. After researching the symptoms, I found that these symptoms are identical to the know lifter problem with that engine. The truck is a 2026 Chevrolet Silverado Trail boss with approx. 3454 miles on it. It's currently at the dealership waiting for them to "diagnose" the problem. I was told that it may just be a "faulty sensor", but after reading other people's experience with this engine I believe that the real problem is a damaged lifter/lifter pin due to the poor design and engineering of the DFM system

The contact owns a 2026 Chevrolet Silverado 1500. The contact stated that while driving 25 MPH and attempting to depress the accelerator pedal, the vehicle lost motive power, the contact attempted to start the vehicle, and the vehicle operated as intended. The check engine warning light was illuminated. A dealer was contacted. The vehicle was taken to a dealer to be diagnosed; however, the diagnostic result was unknown. The dealer cleared the codes, and the vehicle was then taken to another dealer, where it was diagnosed and determined that the ground strap needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the part was on back order and might take six months for the part to do the repair to be available. The approximate failure mileage was 4,000.

This incident occurred 24, June 2024. Time was approx 1745hrs and temperature was 93 and humid. Was stopped at a stop sign, attempted to make a phone call and reached to temporarily turn off the air conditioner by pushing the on/off button. When I pushed the button, it turned off the vehicle engine completely! When I was startled as to what had just happened, I pushed the air conditioner button a second time; It STARTED the truck's vehicle engine! I repeated this test three times in the presence of my spouse who was also in the truck. We then drove approximately one mile and at a second stop again was able to duplicate the engine turned off/on by pushing the air conditioner on off again! It was if the air conditioner on/off button was the vehicle start stop button. I did not try to duplicate this under roadway speed, fearing if the engine did in fact turn off, simply by pushing the on/off air conditioner button. It would most assuredly result in the complete loss of driver inputs for steering, brakes and control.

The contact owns a 2026 Chevrolet Silverado 1500. The contact stated that while reversing, the back over prevention camera failed to function as needed. The contact stated that there was no image displayed while shifted into reverse. The dealer was notified of the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 3,000.

Defect: Engine failure caused by lifter and camshaft failure at 114 miles (5.2 engine hours). The vehicle is at the dealership undergoing warranty repairs. The service department confirmed a seized lifter, necessitating the replacement of all lifters and the camshaft. The incident occurred at highway speeds on the interstate when the engine suddenly began knocking loudly. Immediately after the knocking started, the check engine light illuminated, followed by consecutive "Service Anti-Collision System" and "Service ESC (Electronic Stability Control)" warning messages.

Vehicle purchased new December 2026 and vehicle experienced loss of power and abnormal shifting while driving at only 9000 miles. Engine produced clicking noises and was immediately brought to the closest dealership. Vehicle has been out of service since May 8, 2026, with no repair completion date due to parts availability. Owner continues making payments and insurance payments while without use of the vehicle. Owner has not been given a comparable vehicle which is a huge hardship for the family, especially during farming season. Concern exists regarding ongoing reliability and reports of similar failures involving GM 6.2L engines.
