I was exiting a main highway and when I let off the accelerator the engine died unexpectedly with no prior signs of failure and would not turn over to restart, luckily I was able to coast onto a side street out of the way of moderate traffic. I called GM roadside assistance and had the vehicle towed to my local dealership. The service department confirmed that the engine was seized and needed replaced. My vehicle went through the L87 recall and passed inspection last fall at 29,400 miles, had another oil change at around 33,500 miles. The engine failed at 37,800 miles. I am the original owner and have always maintained the vehicle to GM standards. I feel that the recall is not solving this problem, because the engines are failing anyway. At this time my vehicle has been at the dealership service department for three and a half weeks, and is waiting on the replacement engine. The dealership has provided a loaner vehicle.

Was told to shift to Neutral and restart. Barely made it to the shoulder. App showed only a battery issue and no other alerts. Thankful we did not get hit as cars were flying by on either side on the interstate. Could have been a serious accident. The dealership confirmed that the engine needed to be replaced.

This is separate for VIN [XXX] I had to change dealerships because Beck & Masten South / GMC would NOT provide me with a loaner after being told I was on the list and I was next in line. I waited a month and drove to them and spoke with the girl who oversaw loaners. I explained I had severe safety issues such as front-end wobble which is related to transmission issues. And the oil consumption issue and oil light. Once again, I was re-assured the loaner program was indeed still active and I would be put on priority. Again to no avail I had wasted too much time with Beck & Masten. After months of this I found out I did not have to take it to the dealer I bought it from. So, I took it to Monument Chevrolet. I explained my concerns related to the front-end wobble which was very intermittent. And the oil consumption issue which I was very concerned with due to the year model and mileage of the truck. Also, the 75,000.00 price tag was really has me extremely upset... Monument Chevrolet treated me well. I had actually brought it in and called about the steering which was greatly affected by the severe front end wobble more than one time. I was told at first the oil consumption was pretty normal. Until I told them how much I had to add between changes. I have attached two work orders to this complaint. These work orders show what was done at 18017 miles and 18323 miles. The later work order was when the PICO test was done. Also, an oil consumption test was started once I picked the truck up. After I had driven it for 2077 miles and was bringing the vehicle back to Monument Chevrolet, as instructed for the oil consumption results, when a loud squeeling, then hard knock, power loss and I pulled over. I called Monument and was instructed if I could get it to start and bring it. I drove it to them while knocking and rough running. It has been in the shop for over 2 months for an engine replacement. 2077 miles after recall work! REFER TO: COMPLAINT XXX INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOI

I reported problems with my truck to Beck and Masten South GMC. I was put off a number of times with ridiculous excuses. My vehicle sat in the shop for a month to get my OnStar safety equipment repaired. I also had arguments with them regarding the oil light coming on and it burning excessive amounts of oil. I was told this was normal. I know better. Also, I needed to get it back into the shop for service and inspection for a squeeling noise under the hood. And to have them check the oul consumption. I was told it idle too often, and this was the reason oil was dissapearing. I was told they would put me on the loaner list so I could have means to get to my oncologist for cancer care. Well, I called numerous times because they never furnished a loaner for these issues I was told a third, then forth time I was next in line for a loaner so I could drop it off for repairs and recall work. After 8 months of these lies I finally went to Monument Chevrolet. Beck and Masten never intended to help me. Total I had tried and was told by newer service advisors, the manager, and GMC this would be remedied over 10 times in over 6 months. I finally gave up and moved on to never return to this dealer I had purchased two brand new GMC 1500 trucks from in a two year time frame. I did get my OnStar gateway repaired by replacement. It had stopped working again,shortly after getting it back. I kept getting put off. They stated it needed another Gateway for OnStar. I kept calling,and was told they would contact me ince it came in. I ended up troubleshooting the entire modem/router assy. I found inconsitant configuration parametrs. So, I reconfigured it all from start to finish after clearing the memory by taking battery cables off and allowing it to power down and clear memory. Then I did perform a reconfiguration and username/password change as well. I repaired it myself. The Onstar has never acted up again. These were my first issues. I had to take it to Monument Chevrolet for service

The truck currently has 48000 miles. The 6.2L L87 engine was replaced at 17000 miles. A few weeks ago, I parked it, went to a ballgame, came back 4 hours later and started the truck. Drove it approximately 500 feet and lights started flashing on the dash. It was running rough, had loos of power, and sounded like a diesel. I immediately shut it off and had it towed to a dealer. The lifter on the number 3 cylinder stuck and bent the pushrod. The dealer replaced all lifters on that side of the engine. This all happened after it was checked for the recall and the thicker oil was put in.

On January 16, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25001 after receiving complaints and field reports concerning engine failures in MY2019-2024 GM’s full-size truck and SUV T1XX platform equipped with the L87 6.2L V8 engine. These complainants alleged engine bearing failures resulting in knocking and growling noises from the engine’s bottom end and in some cases more severe consequences such as broken connecting rods leading to engine damage, or engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash.
