ENGINE

Potential Consequences:

While driving home from work, my engine, with only 20k miles on it, started to make noise. I immediately got off the highway at the next exit and as soon as I came to a stop the engine noise got even louder and the vehicle shut off. Was able to barely get it started but managed to get it off the road before it died again. Had it towed to my GMC dealership and have been advised that the engine is done and needs to be replaced. Seems to be a very common occurrence on GM vehicles with the 6.2 engine. Won’t have the truck back for minimum 6 weeks but still have to continue to make my $1000 payment for a truck with no working motor due to factory issues.

Defect Description:

WHEELS

Potential Consequences:

I was driving at approximately 25-30 MPH, accelerating from a stop light and I felt a clunk, heard a grinding noise and my back wheels locked up. It was snowy/icy conditions so the back end of my pick-up slid out to the right a little bit before the wheels unlocked and I was able to regain control. I could have slid off the road or into another vehicle had the wheels remained locked. The computer system then alerted me to a transmission issue and to reduce speed immediately and call for service. The pickup was then unable to shift out of 1st gear. The vehicle has been towed to a dealer and I have been informed the valve body in the transmission has to be replaced which is 8-12 weeks backorder.

ENGINE

Potential Consequences:

Was driving down the interstate at 70mph with cruise control on. The vehicle lunged forward and soon after a reduce power message appeared in the messages. I was able to avoid any incident with other vehicles and exited the highway with the motor was making loud noises. I parked the vehicle and called for roadside assistance. The vehicle had to be towed to the dealer, and I found out that the 6.2 liter V8 motor has metal in the oil and the entire engine needed to be replaced. The thrust bearing failed and required a full engine replacement. The vehicle has approximately 21,000 on it and is still under warranty, but it is a 3-6 month wait to get a replacement engine. I have searched the internet and found that there are many vehicles that are having similar issues with the 6.2 L V8 GM motor. It has been slightly over a month since the incident and have not received any updates.

I was able to avoid any incident with other vehicles and exited the highway with the motor was making loud noises. I parked the vehicle and called for roadside assistance. The vehicle had to be towed to the dealer, and I found out that the 6.2 liter V8 motor has metal in the oil and the entire engine needed to be replaced. The thrust bearing failed and required a full engine replacement. The vehicle has approximately 21,000 on it and is still under warranty, but it is a 3-6 month wait to get a replacement engine. I have searched the internet and found that there are many vehicles that are having similar issues with the 6.2 L V8 GM motor. It has been slightly over a month since the incident and have not received any updates.

Additional Notes:

Was driving down the interstate at 70mph with cruise control on. The vehicle lunged forward and soon after a reduce power message appeared in the messages.

ELECTRICAL SYSTEM

Potential Consequences:

The truck check engine lights came on, and I took it to a dealer. I was told the ECM was faulty, they replaced it, but it didn't fix the issue. I was then told the ONSTAR telematics unit was faulty. The truck has been down for 45 days, with no ETA on parts(several forms say 4-6 months). There is no guarantee that this will fix the CEL. The truck is inoperable at this time.

POWER TRAIN

Potential Consequences:

While entering the highway from a downward slop exit ramp and towing a trailer, my truck shuddered hard and briefly locked up the rear axle. It immediately went into limp mode with a message that driving speed will be reduced. It also wouldn't shift past 5th gear. When the event took place, the OBD2 generated over 20 trouble codes. My local dealer advised I could drive it to them for repair. Upon dropping it off, they now advise it's NOT safe for driving and they have no eta on the parts to repair the issue. It's now been at the dealer for a week with no update. This is a well known issue that GM refuses to repair or provide a reasonable timeframe for repair. There are countless videos such as this one that show what happens when this takes place. [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE

Potential Consequences:

On Saturday March 1st I was driving East on I-10 in Florida when my trucks engine lost power. I managed to get over onto the shoulder of the road and got out of the flow of traffic. Very scared I was going to get hit before I could get off the interstate. Motor was making a terrible noise like the lifters let go. I was beside the interstate for about 3 hours trying to find a tow truck to come get me and the truck off the side of the interstate. I had the truck towed for about 60 mile to get it back home to the dealership. The truck has 26,000 miles on it and the dealership told me the motor was no good and that there is metal pieces in the oil pan. 2 weeks have past by and they can't tell me when they will receive a replacement motor. What am I supposed to do? $80,000 truck 2 years old and the motor is no good. Thanks

ENGINE

Potential Consequences:

I own a 2023 GMC Sierra 1500 Denali Ultimate. The truck had about 19k miles on it when the engine seized while driving on the highway late at night in January. This was extremely dangerous as I was going 55mph over a bridge and lost the engine. I was stranded on an exit ramp unable to move. It was cold that week so it was 5 degrees. Onstar informed me that since the truck could not be shifted into Neutral that it would need dollies and a flat bed. They said they could get to me at 8am which was 9 hours from when the truck broke down. It was 5 degrees out and I had no heat sitting on the highway. I ended up calling a local tow company and they were able to get to me but I had to wait 3 hours. The truck was towed to the deal and they confirmed that the engine seized (it is a known problem) and it needs a new motor. They said there is a big back log of engines because many have this issue. I still have not provided a timeline for the truck to be repaired.
