This is the second of three new trucks from GMC with engine failure, 1st was lifters, and the other two were bearing locked up. All maintenance was performed by the Dealership on all three trucks

Had a prior recall a few months back on my truck in reference to the engine. My truck didn’t have an engine issue such as check engine light etc etc etc which required attention. So they only changed the oil to a different velocity. On Sunday afternoon August 23, 2026 while driving on Interstate 20 near Longview, Texas the truck shut off. I had to get it towed to the Chevy dealership (Peltier Chevy in Tyler, Texas).

engine was replaced by Classic GMC in Katy/Houston, TX in dec 2025 under L87 recall. My wife was driving and was stopped on an off-ramp but still in the traffic lane. It started with a light knock that i thought i heard the day before, but then died on freeway within maybe 15 miles of her driving. Unknown if it knocked louder, but wife says she never heard anything until it died and check engine light came on and engine would not restart. Required tow to GMC dealer. They diagnosed and took 2-3 weeks to source and replace the engine. In july 2026, started hearing very similar noise - this time apparently the water pump seized. Heard noise and got home within about 10 miles. Checked under hood and drive belt was significantly frayed and knocking/metallic noise was intense. Towed to Classic GMC. Not covered under any warranty - my replacement engine did not include a new pump. Cost $1700 at Classic GMC - they said it had no relation to the engine replacement or labor done in December. Unrelated, but icing on the cake - less than 2 hours and 10 miles of picking it up from service, lots of warnings about lane keep, adaptive cruise control, and park sense started going off. Returned to same shop the next day and *poof* the camera and processor that runs all those systems was somehow fried. Unrelated of course. $1200 a but they claimed GM graciously offered to “split the cost with me 50/50” since I just paid so much for the water pump. Picked up from service and traded vehicle in with 2 days.

My truck is at the dealership for a failed transmission valve body. I was doing some research on this issue and saw recall N242454441. I asked the service writer about this and he said my truck was not covered by the recall. I had all of the same issues as described in the recall. effects can cause harsh shifting, setting a service engine soon message, reduced engine performance or P0747 diagnostic trouble code. I was driving along when the check engine light came on then a message on the dash said reduced power mode. I barely made it to work then called the dealership and told them I was bringing it in if I could make it. When I tried to take it to the dealership the rear wheels seemed to be locked up when in drive but would move in reverse. After coasting forward in neutral then reversing the wheels seemed to unlock in drive but then I didn’t have reverse. I have the same drive train with the 10 speed transmission. I think this recall needs to be expanded to include my truck as well as countless others for this known issue.

I was driving to work when my vehicle’s check engine light illuminated, accompanied by a warning message stating, “Low oil pressure—turn vehicle off.” I immediately followed this instruction and shut the vehicle off. When I attempted to restart it, the engine cranked repeatedly before finally starting, but the same warning message reappeared, prompting me to turn it off again. A few months prior, I had the vehicle inspected at the dealership, where I was informed that it passed the 6.2L engine national recall inspection. On April 9, 2026, the vehicle was towed to the dealership for further evaluation. On April 10, I was contacted and informed that technicians could hear a metallic noise coming from the engine. However, they stated that the readings from the PICO test were not high enough to meet the criteria for engine replacement. The dealership recommended replacing the camshaft position sensor but could not confirm whether this repair would resolve the issue. They also indicated that I would be responsible for all associated costs. Despite the presence of concerning symptoms, including abnormal engine noise and repeated warning messages, I was advised that General Motors would not approve an engine replacement unless the engine either completely seizes or fails both required diagnostic tests. At this time, my vehicle has only failed one of the two tests. As a result, I have been left without a reliable and safe vehicle, which is significantly impacting my ability to commute to work. This situation places me at risk of financial hardship and potential job loss. I am seeking a resolution that ensures my vehicle is properly diagnosed and repaired so that it is safe to operate.

Engine failed at high speeds on interstate. When my Truck shut off the steering and braking system went out and getting to shoulder of interstate was difficult with others around me. Express lanes were limited on emergency shoulder therefore my truck was partially on the high speed driving lane. 911 was called out to block freeway lane. Check engine light blinked right when truck shut down.
