ENGINE

I purchased said vehicle with a little over 76,000 miles on XXX from NW Chevrolet, [XXX]. Dealership service the engine on XXX and remained on their lot until it was sold. While driving home, I smelled gas fumes coming into the cabin and the engine was misfiring causing slight hesitation in motor acceleration while adjusting to speed limits and climbing hills. I told management at the dealership about these issues on XXX. My vehicle is currently in the shop to fix the fuel injection system, spark plugs, grounding issues as of XXX to fix the dealerships mistake costing more out of pocket expense. Management will not do anything about it because it was sold (As Is) without a warranty which I refused to purchase through finance and interest charges on a car loan. I purchased a 4-year warranty through Endurance on XXX with a 30 day wait period before filing a claim. GM is letting their dealerships advertise and sell problem vehicles with known motor issues to consumers while marking up the sale price. Vehicles should never be sold until GM fixes all motor defects before advertising to the consumer. The consumer is at serious financial risk when getting an auto loan paying on a broken vehicle.

ENGINE

I bought this truck from a dealer at the end of july 2026 and it only had 27k miles on it. I got the carfax and saw all the times of service and checked that this truck was inspected and went to the new oil type, filter and cap. It also was showing it had the special warranty due to recall. So i assumed everything was good to go and the truck was relaicle. Not even 18 days later and less than 800 miles I broke down mid drive. I was traveling at 45 mph and lost all power and almost caused an accident trying to get over and parked safely. There was no warning light or indication of it breaking down or having a mechanical issue. It went to the dealer and they diagnosed it as complete engine failure due the issue GM is having currently. They did order a new motor and it took two weeks to get in but they are in the process of the engine swap as we speak. I am sure i will get more details this week....but I am concerned now amd honestly wish I wouldnt have bought this truck considering I am seeing reports of new motor swaps having catastrophic engine failure two or three times. So at this point im in limbo waiting for the new install and hopefully it doesnt fail again

My truck has the same issues for the transmission and engine problems I have taken it to 4 dealerships and they all say the same thing. The first one I spent about 3 hours there and they changed the 20 oil to the 40 oil and said that will fix the issues but it hasn't i called GMC to report this and they sent me to the others but they said it's been looked at and I know one of them didn't do anything to see the issue.Gmc called the other day and I told them I will let the engine locked up or the transmission keep doing the same thing and they'll have to fix the issue then.I do have 109000 miles on it but thus issue has been going on for 4 years they said I have 150000 miles for the issue but I do t think that is right.I paid them cash money for the truck when I bought it

ENGINE

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

The vehicle’s engine suffered a catastrophic failure and locked up while in operation. The engine is still installed in the vehicle and is available for inspection upon request. The engine suddenly locked up while I was driving, causing the vehicle to lose power and become disabled in traffic. I was forced to get the vehicle out of the flow of traffic and have it towed to a safe location. The sudden engine failure created a significant safety risk to me and other motorists, particularly because the failure occurred while the vehicle was being driven. Yes. Integrity Buick GMC in Chattanooga inspected the vehicle and confirmed that the engine had locked up. Only the dealer. No.

NHTSA complaint #11758601 — an unverified report by a vehicle owner.

ENGINE

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.

ENGINE

I Purchased the vehicle on May 29, 2026 and it stated the 6.2 liter engine recall had been fixed and that I have extended special coverage for the exact issue of the recall until 150008 miles on this vehicle. On July 14, 2026 the vehicle was being driven and stalled out at a traffic light and restarted, yet within a quarter mile it stalled again at the next traffic light and became completely disabled, it would not even allow a shift into nuetral, so I had it towed less than 100 feet into the Walmart on Loudon Road in Concord, NH 03301 parking lot. On July 23, 2026 I was able to get the batter charged and attach a code scanner which showed one code (P0016). Pursuant to Recall N252494001 (which had allegedly been repaired, likely with the bandaid fix of thicker oil) any 6.2 liter GM truck with the loss of propulsion needs to be plugged into a scanner and if code P0016 is present, engine replacement is needed. Specifically noted to the recall is Special coverage N252494003 which provides the coverage to 150,008 miles on this vehicle is directly related to the recall. At the time of loss of propulsion the vehicle had 99,195 miles present on the odometer. The following day July 24, 2026 I had the vehicle towed to Banks Chevrolet GMC in Concord NH, after the vehicle arrived, I spoke with the service department, provided them with the recall paperwork and printout of the special coverage uner the vin as well as a photo of the odometer and my scanner displayining one code P0016. They then informed me it would take them until August 24, 2026 to "diagnose" the vehicle. The recall is clear it just needs a code scan if disabled. I have contacted GM and informed them of the need for a loaner as the vehicle is a vehicle utilized for business. I have since been told they will try to look at it earlier and no loaner will be offered but I "may" be able to be reimbusred $44.00 a day for a rental. There are no rentals for that price that can tow over 9500 pounds. It is unnacceptable.

ENGINE

On November 20, 2025, my 2022 GMC Sierra 1500 AT4 equipped with the 3.0L Duramax diesel engine began experiencing intermittent engine overheating conditions. Concerned about a potential safety issue, I contacted a GMC dealership and was advised that because no diagnostic trouble codes were present, there was nothing to diagnose or repair and that I should continue driving the vehicle. Over the following months, the overheating condition continued intermittently. On May 24, 2026, while driving on the highway, the vehicle suddenly overheated, displayed fault code P1098, and entered reduced power ("limp mode"). The vehicle lost normal performance and acceleration while traveling in traffic. This created a significant safety hazard because the vehicle was unable to maintain normal highway speeds, increasing the risk of a rear-end collision or other traffic accident. The loss of power occurred while driving and without sufficient warning, leaving the vehicle unable to safely perform as expected in highway traffic. After researching this issue, I found numerous reports from other GMC and Chevrolet owners describing similar overheating, coolant control valve, thermal management system, and P1098-related failures. Many owners report symptoms involving engine overheating, reduced engine power, and limp mode operation while driving. I am concerned that this may indicate a broader defect involving the vehicle's cooling system and thermal management components. The vehicle exhibited overheating symptoms for approximately six months before the final failure occurred. Additionally, I understand that certain GM vehicles have been subject to service actions involving coolant control valves and thermal management system components. Given the similarity of symptoms, I am concerned that the overheating condition reported in November 2025 may be related to the same type of failure mechanism, yet my vehicle has not been included in any recall or special coverage program.
