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.

Welcome to the forum @usaffiremanboyd

How may stages does the claim have to pass through to finally get approved/denied?

I heard of situations where people had to contact BBB Auto Line to help them get through the lemon law process, mainly because GM can make it more difficult than it should be.

2021+ Tahoe problems are never ending it seems, and I'm actually surprised that's all you experienced.
Here are some others I saw being reported.

1. Brakes recall
2. Key fob not found while driving
3. Right rear door handle cable broken
4. Service Safety Restraint System light on
5. Steering column box replaced
6. Rear power outlet not working
7. Title or vin number incorrect. Shows preowned!!
8. Rear window sensor out
9. Rear wipers don't work

Note sure but my claim was denied a few days ago. Assuming it only got through a couple of stages. Still working with them.

Update: Tahoe is still at the dealer. They replaced a coolant pump yesterday, drove it and the check engine light came back on. They have to get in touch with GM techs again on Monday to see what the next "fix" will be. They think the next step to replace is a water cooler part that has the sensor installed in it or bring some GM technician in that can see/do more with the computer of the vehicle that the normal dealer techs can see/manipulate.

Super frustrating to say the least, almost been at the dealer for a month now and still making payments on a vehicle i'm not driving. I will say this, the dealership (service manager) has been very good. I have a loaner, so that helps. My issue has gone up to the "district manager" and they are aware and concerned as well.

Three days ago, GM denied my replacement claim, I thought my next step would be to go through the BBB but GM told me if I did that, i would null and void and "compensation" they could give me after the issue is resolved.
