2026 Chevrolet Silverado 1500

On January 16, 2026, the Office of Defects Investigation (ODI) opened Recall Query RQ26001.  This investigation was opened to assess the remedy effectiveness of Recall 25V-274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V-274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GM’s recall remedy for Recall 25V-274 consisted of two different repairs, either an oil viscosity change or an engine replacement, based on the results of the remedy inspection procedure. ODI continues to receive reports of engine failures after the completion of the recall remedy. To date, ODI has received 499 complaints alleging post-remedy engine failure in vehicles subject to Recall 25V-274, 473 of which involved an oil viscosity change and 26 a complete engine replacement. Additionally, ODI has received 191 reports of L87 engine failures in engines produced after the production period cited in Recall 25V-274. GM reported receiving 6,953 complaints of post-remedy engine failure. ODI is opening this Engineering Analysisto continue investigating complaints of post-remedy engine failure. ODI is expanding the scope of this Investigation to include engines produced after the production period cited in the recall. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

The contact owns a 2026 Chevrolet Silverado 1500. While driving at an undisclosed speed, several brake warning lights illuminated on the instrument panel. The contact attempted to depress the brake pedal, and the brakes failed to respond as needed. The contact pumped the brake pedal continuously to bring the vehicle to a stop. The vehicle was then driven in LIMP Mode. The vehicle was taken to a dealer and was diagnosed with a brake control module failure, which was caused by an incorrect software version that had crashed the module. The manufacturer was notified of the failure. The failure mileage was 4,300.

Picked up truck at the dealership with a friend and stopped at Restaurant across from the dealership. I backed into a parking spot and shifted into Park and pressed Button to shutdown Engine. No audible warnings were given to indicate that I did something improperly. We exited the vehicle and the only sound heard after I closed the door was the audible alarm that reminded me that the spare key was inside the vehicle. We walked approximately 30 to 40 feet and heard a crack from a limb that the truck struck as it rolled backwards down a small hill and crashed into a building. No one was hurt. Upon checking the vehicle, we noticed that the shifter indicated that it was in Reverse after impact. Onstar was notified because of the crash and we relayed to it that no one was hurt. Truck taken to Body Shop.

Engine seized and stalled while vehicle was in motion. This resulted in failure of power steering assist and power braking assist. This made vehicle extremely difficult to maneuver safely out of the flow of traffic. The engine seizure was confirmed by a Chevrolet dealership. And the engine was replaced by the Chevrolet dealership. There were no warning lamps. The engine made some unusual noises moments before failure.

While driving in a parking lot. Barely applying throttle to move straight forward not turning or driving on a rough road the truck completely shut off all screens went blank and I wasn't able to accelerate. I was able to restart the truck, shift into drive and continue but took a few seconds to realize the issue and properly restart the engine. Thankfully this occurred while in a parking lot without anyone behind me but this is a real concern for me now driving on streets/highways with other vehicles around. This truck was purchased brand new has never been off road and has just over 3,100 miles. There were no warning lights before or after this incident.

While driving at about 20mph we hear a grinding noise and the truck throws itself into nuetral and then shut off. The truck seems to be on like when started with the key fob, on but not fully started. A warning message comes on the dash stating "conditions not safe to drive". The truck would not go back into gear, even after pressing the start button and truck regaining power. Pressed on the brakes to stop, put in park and then back into drive. Message warning went off and truck drove as normal again. This has happened twice since purchasing the vehicle in May 2026.

Was driving at highway speeds when truck shuttered and rattled and quickly slowing down. Warning errors on dash stated "Reduced Acceleration, Drive with Care", "Service Emissions System", "Service Traction Control", "Service ESC". Got vehicle to dealer and they confirmed the error code (P0202 - covered under powertrain warranty), but then also noted an error code for P129F where the truck would not start up. They are recommending a replacement of the Fuel Pump Power Control Module. GM had updated a NHTSA bulletin (original: N262558690 - Emissions Recall - Fuel Pump Power Control Module - July 15, 2026) on August 12, 2026 that expanded the population of qualified models to include the 2022 GMC Sierra 1500. However, on September 1 they issued an updated notice that said "GM has since identified certain 2022-2023 model year Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles that were erroneously included in this recall and are not affected by the condition." I believe my truck was originally included in the recall, was removed two weeks ago, and now my dealer has subsequently diagnosed a Fuel Pump Power Control Module failure with DTC P129F and recommended replacement This all follows a warranty repair I had to get two weeks ago on my Engine Coolant Control Valve (P1098), which was covered under powertrain warranty
