NHTSA Complaint #11707931 — 2025 CHEVROLET SILVERADO 1500

On 11-20-25 while driving vehicle home a loud noise was heard coming from rear of engine. After review and consultation with automative technician it was thought best to park truck in safe location at house and have towed to dealership as engine noise identified aligned with other reports of thrust bearing failures associated with this engine. Driving engine further was considered unsafe if further damage occurred the engine could seize up while on highway. The Dealership tested engine on 11-21-25 in accordance with GM technical service bulletin and confirmed a thrust bearing failure had occurred. A replacement engine and turbo were submitted for order, but not available to due to back order of these parts due to large number of failures of same engine this year. Only the GM dealership that I purchased car from has inspected vehicle at this time and there were no check engine lights in vehicle when failure occurred. I have since identified the GM technical service bulletin was published in September of 2025 and the Duramax 3.0 has had numerous failures throughout 2025, prior to my purchasing vehicle at end of October. GM manufacturing misrepresented the quality of vehicle during the new vehicle purchase and did not disclose the significant number of engine failures that have occurred this year that could have left me and my family in an extremely unsafe situation. Additionally there has been no communication on how the replacement engine equipment manufacturing has resolved the issue that created the initial failure and I am concerned of driving vehicle in future as the engine failure may occur again. NHTSA needs to record this incident and request to GM failure rate data this year and investigate GM for selling vehicles with known manufacturing issues that place driver/passengers in an unsafe condition when vehicle looses power while driving.
