NHTSA Complaint #11619285 — 2021 GMC YUKON

I bought a brand new Yukon Denali in 2021. In 2022 at 12,000 miles, the car was riding extremely rough. It was diagnosed as a transmission issue and the transmission was rebuilt after 90 days in the service department at a GMC dealer. Later in 2022, I started getting low oil lights on the dash. The car was brought back to GMC and I was told that there aren't any leaks evident so nothing was done. This happened repeatedly over the last 2 years, at multiple GMC service departments. No leaks, nothing to see here. Last week, the car started shaking violently while driving, with multiple warning lights appearing on the dash. Finally the car just died and I had it towed to yet another GMC dealership. This time I was told that the bearings, piston rings and lifters were all to blame and the car needed a new engine. Of course, now the car is out of warranty. GMC needs to remedy the engine issues in the 2021 models. There are MANY reports of this happening with this engine.
