Bought my 2021 Tahoe Diesel High Country at the end of January. 30 minutes after driving off the lot, the check engine light came on. Took it back to dealer the next day. They read the codes, sent them back to GM, and GM stated a temp difference or something like that. Went back to pick it up, got 15 miles down the road, check engine light came back on. Took it back again, this time they said it was a coolant hose that ran to the water pump was kinked. They replaced the hose to ensure it wasn’t kinked. Went back to pick it up, again got 15 miles down the road and the check engine light came back on. This time, GM is recommending they change the water pump. It’s currently still at the dealer awaiting repairs. I’m sure the people reading can imagine my frustrations with spending $80k on a vehicle and have this many problems so soon after a new car purchase. I contacted GM about a vehicle replacement/lemon law claim. It’s currently been through the first approval process but I imagine there are many more approvals in the chain before it actually gets approved or denied.
After all of this, I guess my question is: Has anyone been through the new car replacement process with GM? Has anyone had any troubles with their 2021Tahoe Diesel like me?
I’m just frustrated and wanted to tell my story and hear what others have to say.
