Faulty valve body Safety was put at risk, I was traveling on a 4 lane road at 45 mph when my vehicle experienced a significant jump in RPM with immediate loss of propulsion. I immediately drove to the dealership as the incident was frightening. The vehicle was also not able to go into reverse. This valve body failure issue has been confirmed by the GM Chevy Dealership, and GM corporate executive services. My vehicle has been undriveable and at the dealership since 3/4/25. This is a known issue with GM, parts are not available and are back ordered with no ETA on when they will be available. Even with a replaced valve body it is likely the vehicle will have future transmission issues &/ additional valve body failure. Please strongly consider a recall related to this known issue and safety concern.

Dear. My name is [XXX] . Phone # [XXX] . My email: [XXX] On [XXX] my Tahoe suddenly shut off while I was driving over 70 mph on the highway. It was towed to the South pointe chevrolet dealership in tulsa. I was told a fuse had failed and paid nearly $400. On April 17, 2025 they returned my Tahoe and said it fixed. [XXX] When i tried to start engine, then it acted like something almost can't start, then i text dealership and told them situation. On [XXX], the same failure occurred again — again at highway speed — nearly causing an accident with an 18-wheeler. The Tahoe was towed a second time. 2 times i was able to re-start engine drive until i stop then can't start it agian. Both time i smell something burned when i tried to re-start it. On April 21, I texted the service manager about GM TSB N252494000, which describes propulsion loss involving the L87 engine — the same engine in my Tahoe. Two days later, I was sent an invoice for $865.30 for a starter replacement. I was told the repair would not be covered under warranty — despite the vehicle still being under 60,000 miles at the time and the defect appearing to fall under a known GM issue. This is a recurring, life-threatening failure that GM and its dealer have not fixed. The vehicle is still under warranty, yet GM is refusing to cover the repairs.

While driving down the highway, the vehicle suddenly experienced multiple issues. The headlights went out, the vehicle would not continue to accelerate, and all interior lights shut off. The vehicle then shifted into neutral and stalled. There were no warning signs or indicators before this happened. Our safety was at risk as we barely managed to pull the vehicle over to the shoulder, with no working emergency lights. The highway had no street lights, and we were constantly worried about being hit by other cars since our vehicle was nearly invisible without the emergency lights. The malfunction left us stranded more than two hours from home. We had to have the vehicle towed to a Chevrolet dealership for inspection, which was also over two hours away. Prior to the failure, there were no warning lamps, messages, or other symptoms—everything happened suddenly without any notice.

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.

The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001). GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274. This presents a potential safety risk that warrants further investigation.
