I have a 2021 suburban bought new in January for 70k. Been in the shop for 12 days. The engine basically blew the first time I Hauled a boat at 5,000 miles., It was clunking, knocking, misfiring and all alerts going off while I was trying to get home from a long trip. Took to shop. Lifters stuck, push road bent, after those were replaced, it sounded even worse, its now been in the shop for an alternator, water pump, coolant leak, the list goes on. I haven't had the car for 12 days. GM is stumped now on what to try next and is tearing the engine back down. I will not accept the car back, working with GM on a repurchase. There is no reason this should have happened at 5,000 miles, brand new....
