Engine module reprogramming completedNext. On 3/07/26- dropped off my Sierra truck at dealership. Ticking sound. Confirmed engine replacement was needed even after the oil viscosity change. 4/22/26- Replaced engine assembly, radiator, gaskets, hose, belt kit. At the time of the engine replacement, the truck had only 16,756 miles. As of 8/25/26, having an oil compression test completed as the replacement engine has been excessively burning oil. Needed the dealership to complete an official text for GM, but from checking the oil, the vehicle has short @ 1quart of oil every 1,000 miles.

ENGINE
At approximately 14,000 miles, the 6.2L V8 engine experienced a major failure due to a spun main bearing, which resulted in the complete replacement of the engine. The vehicle remained at the dealership for more than 60 days while the repair was completed. After receiving the vehicle back, it operated without any significant issues until approximately 30,000 miles, when the engine experienced another major failure. This second failure was attributed to the lifters, and the engine required substantial repairs and ultimately had to be rebuilt. Having two major engine failures before reaching 30,000 miles—first requiring a complete engine replacement and then requiring the replacement engine to be rebuilt—has raised serious concerns regarding the vehicle’s long-term reliability and durability.

POWER TRAIN, ENGINE
I was driving north/east on [XXX] just outside of [XXX]. After accelerating to give another driver room to move out of his lane that was ending, I lost propulsion/power. The Sierra went into Neutral and told me something like "Press Start to resume". I had to immediately get off the interstate as I was rapidly losing speed. I was able to pull over to the shoulder of the interstate on the right, just before exit 2. After getting the vehicle parked, I was never able to restart the vehicle. The motor would not turn over. The display screens kept cycling between a blank display and a display that looked like the vehicle was on but the engine never turned on. When I tried to start the car, I got a message of "conditions not correct for shift". We could not even get the vehicle into Neutral. I used OnStar to get State Patrol to show up and put lights behind us for safety. OnStar should have a recording of this call. This was on Saturday XXX in the ballpark of 2:30 pm central time. I would imagine the officer also filed a report, but I did not get it. The vehicle was towed to Billion GMC in Iowa City. Billion GMC said their initial suspicion is the 6.2L motor failed / locked up on us as this is know issue that is subject of a class action lawsuit. These vehicles ARE NOT SAFE to be on the highway, someone is going to get seriously injured, please do everything you can to get these 6.2L engines off the road before someone dies.

ENGINE
On [XXX] I was driving my 2024 GMC Sierra 1500 Vin # [XXX] on a major highway in Houston when without warning the engine shut off, stranding me in the middle of busy traffic. I was able to get to the shoulder and restart the truck, but no warning lights came on so I continued on my drive when approximately 20 minutes later, while still on a busy freeway, the engine shut off again. I was able to restart the truck and within another 15 minutes the check engine light appeared, the engine lost power and started making a loud rattling noise. Roughly 2 minutes later, as I was attempting to pull over to the shoulder and safety, the truck shut off and would not restart. This was the 3rd time for it to stall out on a busy freeway which was very dangerous for myself and the other drivers. I contacted the local Chevy dealership and they sent a tow truck out to tow the truck back to their dealership service center. I was later contacted by a service advisor that said they found a code P0016. He informed me that the engine would need to be replaced. As of today 8/11/26, they are still waiting on backordered parts to arrive before they can even start on any repairs.

ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
Was traveling home and started losing power going up a hill on XXX. The truck was surging, the check engine light came on and an audible warning of no (low?) oil pressure. The truck shut off on a busy interstate highway and barely got onto the shoulder. The tow truck driver had to lay on the ground with part of his body in the lane of travel to place "skids" under the rear tires because there is no way to place this vehicle in neutral for a tow without a special GM tool. When I contacted Harry Robinson GMC service center in [XXX], they told me that it was no longer a safety recall because the truck had passed diagnostics and new, high viscosity oil was put in the truck XXX. The GMC app says code P0016 which is the dreaded 6.2L camshaft to crankshaft alignment that accompanies engine component failure.

TIRES, TIRES:TREAD/BELT
I bought this truck from a reputable GM dealership 2.5 weeks before this happening occurred. Tires only had 50k miles on them when they were rated for 80k miles: the front driver side Ttire ruptured while on major hwy in texas. No signs of air loss and the road was clear of any debris. Steering started to lightly shake and eventually came to a violent shake, then the front driver tire ruptured. Uncontrollable steering from the rupture caused the truck to slam and scrape into the concrete dividing barrier. If it were not for the other drivers around and being then cautioning their driving behaviors, this may have resulted fatally. Other drivers and my self may have easily collided with each other on a major traffic highway. I’m still extremely mindful of this happening again. This caused me as a customer, originally thinking this tire manufacturer is to be trusted, to not being a customer any longer as well as causing nearly $30,000 of needed repairs. From what I am reading from this site, plenty of other drivers have experienced the same, almost identical happenings. This is a safety issue that needs a recall on this line of tires and the manufacturer should be liable for all costs to the consumer witch includes vehicle rentals, hotel fees and insurance deductibles, s as well as the entire bill of repairs the insurance companies dish out. It appears from all of the complaints, Goodyear is producing unsafe products that is endangering consumers’ lives. Do the ethical thing Goodyear. Stand behind your product and protect, honor your customers. I have requested a subjugation claim with my insurance provider. The ruptured tire and related wheel are in my possession, available for inspection upon request. Police and GM roadside assistance were called as Onstar was prompted.

Ever since I bought this truck new, I noticed a lot of metal shavings and debris in the oil filter every single time I changed the oil. I took it to the dealership multiple times to have this looked into before the engine recall came out. The dealership took pictures of the metal and sent them to a General Motors engineer, but the engineer just told them it was "normal." Later on, the truck went in for the official recall inspection, passed the PICO test, and nothing was fixed. Then on August 4, 2026, I was driving on a crowded expressway right through a construction zone with absolutely no shoulder to pull over on. Out of nowhere, the truck started hesitating badly, lost power, and the engine started making a really loud knocking noise. It was barely running, and it was incredibly dangerous because there was nowhere to go and traffic was heavy. Luckily, I was able to limp the truck along just far enough to clear the construction zone and pull over safely.

While driving on XXX I received a message on the dash: service transmission, will not be able to shift soon. I went to the nearest GMC service center, located in [XXX]. Their diagnostics indicated that the Gear Shift Control Module needed to be replaced with new PN 86421783. That part was not available until XXX, but old PN 86274946 was available at a few dealersships, and it acould possibly be ordered and arrive sooner than XXX. I was told that driving the truck would be okay, but the part should be replaced as soon as possible. I live over an hour's drive from [XXX], and with the assurance that driving the GMC was okay, I chose to have the part shipped to and replaced at the dealership in [XXX], the nearest one to [XXX]. I drove back to [XXX], stopping at the Waldoboro dealership to make an appointment for their inspection of my truck, their troubleshooting the problem, and ordering the necessary parts to repair the transmission. When the part number went into their ordering system, the dealership was advised that no parts were available and no availability date was known. I contacted GMC Customer Assistance to express my concern and request assistance in locating the parts, but she was also unable to locate the parts or speed their availability. Again, on the assurance that the truck was okay to drive, on XXX I drove to my storage units near [XXX], and when I tried to leave and shifted into reverse the truck would not move. AAA towed me to the dealership in Waldoboro, and the replacement parts search began. Finally, on 7/28/26 I was advised that the part was at the dealership, and on XXX I picked up my repaired GMC truck.
