While I was driving, the dash screen read "Press start button" and suddenly the vehicle loss engine power and I had to veer to the far right lane. Luckily the cars around me swerved away. I had initially called OnStar, but when the police arrived they told me I couldn't wait for Onstar as I was impeding traffic so they called a local tow truck and they towed it to my house. From my house, OnStar towed it to the GMC dealership. The dealership stated the engine has locked up and needs a whole new engine replacement.

I was driving on a rural and narrow 2 lane road with next to no shoulder when my engine started losing power. There were no check engine lights or other indicators of failure until the final 2 seconds. At that point, a message popped up on the dash stating something along the lines that my engine oil was too hot and to idle the engine. 2 seconds later, at 50mph my engine died. That is scary enough, but I was also towing a 5,000lb+ trailer, it was -3F, heavy winds, and I had my 2 dogs with me. Thankfully, I kept my wits about me, remained calm, and made it to the side of the road. As mentioned, there was not much shoulder so this put me in great danger of being hit by careless drivers speeding by. The nearest police officer was an hour away, so I was in quite a predicament. Had this happened to most other people, the narrative would have ended much differently. Come to find out, this is a common issue with these 6.2l engines. So much so, that there is a backorder on the engines due to the high replacement demand. This poses extreme danger not only "in the moment" of failure, but also the environmental dangers/risks users are potentially exposed to, just as I was. This needs to be a recall as this is a substantial and immediate safety issue in my opinion.

When driving leaving my home and about 2 miles in operation the truck lost power. Not realizing quite what was happening looking at the instrument panel I noticed a drop in RPM and speed. There were no other indicators of problems and The check engine light didn't come on. Instinctively i pushed the accelerator down with no response. Now realizing that the truck was having problems I tried to get off the road. The area of malfunction was not a good place to stop and did the best I could, the truck half out of the traffic lane. In trying to restart the truck which turned over but would not restart. I felt it was acting like it ran out of fuel, checking the fuel gage which indicated 3/4 tank. The truck was towed to the dealership. During the intake conversion the employee stated " it's probably the fuel control module " which I thought was odd at the time with no one even looking at the truck. Finally results was the fuel control module. I am thinking back on how the truck abruptly came to the stop that I was not in a center lane of a busy highway. In my research I have noticed that there seems to be an updated part number and replacement for this OEM fuel module. I did order a spare to have just in case this happens again. Few things I find interesting is that the dealer knew what the problem was during intake, had one on the shelf and replaced it and had me going the next day. This incident i surely wouldn't want to happen to my wife, anyone on a busy highway or other unsafe situation that the engine needs to in operation.

The reverse lights are too dim to provide sufficient viewing of the rear of the truck when it is dark outside and there is no other lighting. Almost nothing can be seen from the rearview or sideview mirrors, and the backup camera is rendered useless. GM changed the design of the taillights such that they are now sealed, which means owners cannot upgrade the reverse lights with stronger LEDs any longer. This lack of lighting is more than an inconvenience; it is a safety issue. This is a known issue and GM is well aware of it.

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.
