I was driving my yukon xl with my family and as I was coming to a stop at a stop light my Yukon started to shake violently and make a pinging noise. The check engine light came on and as I drove the car smoke started to come out the exhaust. Luckily I was not on the highway as this could have been a serious safety issue for me and my family. I had my car towed to the dealership and they said the 8th cylinder was completely seized and that it was due to the connecting rod and crankshaft. The engine needs to be replaced. I have maintained my Yukon regularly as recommended by the manufacturer and the car was driving great with no issues or warning of having issues until this engine failure suddenly happened.

2021 Yukon Denali 6.2L V8, 137k miles- engine failure—driving down road 55mph and engine light came on, along with check esc and check traction warnings, vehicle began to rough idle and shake, motor knocking. Personally feel this is related to recall but my vin not included says dealership- I feel this recall is affecting way more vehicles than vin’s included. Dealership charged 220$ to plug it in, codes weren’t specific for problem. They are stating “lifter is bad and possibly cam, won’t know if the lifters scarred the cam until they take it apart” and charge me at least 6k is price quoted. No warnings at all before this happened. 137k miles so out of warranty. This put myself and kids in dangerous riding condition as I had to stop and have vehicle towed to dealership.

engine failure from the connecting rod and/or crankshaft. There is a current recall for this and my vehicle should be a part of it. I broke down on the side of a highway and had the vehicle towed to GMC dealership. There are now warning lights on with code P0016 and P0324

Vehicle could not detect key fob, key fob had normal operation(lock, unlock, remote start, tailgate open and close, all functional) but unable to start vehicle or power vehicle accessories. Windows opened with key fob and could not close windows, could not put vehicle in neutral, was stranded for 6 hours, unable to scan vehicle due to lack of key detection not allowing accessories to operate to attain connection with modules, unable to tow because couldn’t get vehicle in neutral. Vehicle battery good, key fob battery good. Was stuck with vehicle because couldn’t not close windows. Very unsafe and inconvenient situation.
