GM engine failure investigation overview:
- Who: The National Highway Traffic Safety Administration has launched a preliminary investigation into nearly 878,000 General Motors vehicles.
- Why: The investigation follows reported incidents of engine failure in certain vehicles.
- Where: The GM engine failure investigation is active in the United States.
The National Highway Traffic Safety Administration has launched a preliminary investigation into almost 878,000 General Motors vehicles following complaints of engine failures, Reuters reports.
The probe targets specific models from the 2019-2024 production years, including Chevrolet Silverado, GMC Sierra, Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon, and Cadillac Escalade trucks and SUVs equipped with the L87 V8 engine. In total, an estimated 877,710 vehicles are involved in the investigation.
The NHTSA received 39 complaints and additional early warning field reports from drivers, many of whom noted that there were no signs of trouble before the engines failed.
Initial probe will assess severity of GM engine failure, NHTSA says
The investigation, categorized as a preliminary evaluation, will allow NHTSA’s Office of Defects Investigation to determine how widespread the issue is and whether it poses significant safety concerns. This phase will also help assess the severity of the problem.
Vehicle owners have so far reported incidents of bearing failures leading to engine seizures or cases where the engine block was breached by a connecting rod, according to the auto safety regulator.
Such failures could cause the engine to lose power suddenly, increasing the risk of accidents. However, no crashes or fires have been linked to the issue so far.
GM has said it will cooperate with NHTSA throughout the investigation, affirming its commitment to addressing safety issues. The outcome of the probe will determine whether a broader recall or additional safety measures are necessary, the Associated Press reports.
Meanwhile, GM recently issued a recall for more than 7,600 model year 2025 Chevrolet Equinox electric vehicles over concerns they may not make a sound loud enough to alert pedestrians of their approach.
And last year, GM reached a $35 million fuel pump settlement resolving claims the company equipped GMC Sierra and Chevrolet Silverado trucks with defective engine parts. The class action lawsuit claimed GM sold trucks with defective fuel injection pumps that cause engine failure. These pumps allegedly generate metal shavings that contaminate the fuel injection system.

90 thoughts onNHTSA to investigate General Motors over engine failure complaints
I have had a similar scenario involving my Silverado. My local dealership not only gave me the “run around” in a shady manner, they also told me they would not service this truck, that was still under manufacturer warranty. For problems that had been addressed to me in a letter sent a month prior that had been lost in the shuffle. The dealership didn’t ever mention a word and neither did GM corporation during the many conversations that transpired. Of course, when the cold weather arrived and my “remote start” feature was inoperable the larger service center I chose mentioned: this was an obvious selling point and asked when they could have the vehicle “for a few days” regardless of the 8 more hours their service dept. was open. Finally an honest salesman called several days later after I had read this article and said we would love to have your ongoing repeat business, if you’re not happy in that truck that is giving you problems let’s see what else we have here. In other words try to trap me in an upside down loan. I had the revelation: what are the chances that these 40 people have “gm financial” carrying their titles? While recognizing financial trends are pushing subscriptions, I connected an OBD II scanner to mine and 8 codes reading: “Manufacturer Control” throw a check engine light every second time starting. Now after the sales manager mention the engine I have is his family’s “favorite” I’m curious what will happen when GM financial recognizes my credit union has given me a confirmation number from their full “pay off” (@ half APR refi). I’m guessing since I didn’t comply with the subscription pkgs they aren’t as interested in keeping me as a customer. Because when I asked if their service ctr could modify my 1987 R10 with seat warmers,,, well then there were big smiles all around.
