ENGINE
Engine timing chains failed at 71,000 miles requiring a $9,700 repair. Warranty covers 5 yr/ 100k miles and was not fully covered by GM since the vehicle was 9 months beyond 5 years, yet still well within the 100k miles. Issue was diagnosed via P0016-00 being set indicating misalignment between crankshaft position sensor and the intake camshaft position sensor. This issue is a known problem with the early LM2 engines, and the timing chain was upgraded in later LM2 engines. Early adopters of the LM2 are left to pay the price for a defective part.

ENGINE, POWER TRAIN
Constant engine issues, cams, lifters. Transmission problems. These engines in these vehicles need to be RECALLED. I have bought 6 of these trucks and all of them have the same issues. SPENDING 14k on new engines one after another is ridiculous. These are classified as “work” trucks and can’t handle “working”

SERVICE BRAKES
This has now happened 4 times and I'm taking the truck to the dealership to figure out what the issue is. At high speeds, 65 to 75 mph, on the freeway, the rear brakes suddenly lock up for no apparent reason. Extremely dangerous for myself and surrounding vehicles, especially behind me. The most recent incident pretty much gave me whiplash because it's unexpected with no warnings whatsoever. The freeway was clear, with light traffic. I was almost rear ended because the vehicle behind me had no reason to believe the my vehicle was going to suddenly come to an abrupt stop. I looked up any known similar issues for the 2023 model, and found that there GMC did a recall for similar issues on the up to 2022 models, but that the issue had been resolved. Obviously it hasn't.

UNKNOWN OR OTHER
The front chrome grill indicated in the recall came off while my wife and I were driving at 70 miles per hour. A big rig was passing in the on coming lane at the time. The part came off striking our front windshield almost causing a wreck and causes emotional trauma. It was a very scary experience. Our local dealer supposedly ordered the part two months or more ago from GM. They told us two days after the failure the part was still not available. I called GM who stayed the part was shipped well over a month and a half ago. Someone isn’t telling the truth. This incident should never have happened to us since it was a known safety recall. It should have been replaced.
