35” Passenger or Standard Tires
It’s finally time I pulled the trigger on a lift and tires for the AT4. We have a ‘21 with Magnetic Ride and 20” wheels. I would like to preserve the ride quality as much as possible so I’m looking at Passenger or standard load tires. I’ve only found two examples of >34” P rated tires...- Taos_AT4

Whelp, confirmed. Failed lifter on the right bank, bent push rod, etc. I'll share more details in the morning. They told me they only replaced the right side, but the service receipt shows parts for 8 lifters. I'm not familiar with engines to know if there are 8 on each side or not. Could that...- Taos_AT4

Lifter Club
Could possibly be joining the club. At 17,100 miles our '21 Yukon AT4 with a 3/21 build date freaked out on my wife right as she was pulling into the driveway. Had it towed to the dealership yesterday. Still waiting on confirmation, but all the symptoms are lining up. Question, when you are...- Taos_AT4

2nd time Lifter Failure... 2021 Yukon AT4
Quick update. Was at the dealership this morning for an oil change on our other vehicle and was able to check out the build date. If I am looking at the correct label (bottom of the B-pillar where the drivers door meets the rear passenger door) mine has a build date of 3/21. Wasn't able to talk...- Taos_AT4

2nd time Lifter Failure... 2021 Yukon AT4
I'll have to check next time I'm at the dealership. Called GM Roadside assistance and they towed it to the Chevy dealer here in Taos. They originally wanted to tow it to a GMC dealer in Santa Fe because the Chevy shop wasn't pulling up on their end. After providing the address they were able to...- Taos_AT4

2nd time Lifter Failure... 2021 Yukon AT4
Thanks for the advice. The Chevy dealer here in Taos is pretty small, so I thought the lead time was reasonable. Initially after hearing that lead time my plan was to drive the 60 miles to Santa Fe, but after reading about the issues, I decided I would have it towed to the dealership here in...- Taos_AT4

2nd time Lifter Failure... 2021 Yukon AT4
Morning Folks, First post here, which is unfortunate because I really like our AT4. Two days ago, my wife called me about the car suddenly shaking and several warning lights popping up. After a little research, I think we are experiencing the same issue. We have a 2021 AT4 with the 5.3L...- Taos_AT4
