Test drove a Tahoe, read new reports of trouble daily and also compared multiple owner ratings from several car rating services and compared to last years model.
I don't think your experience with one sample and a few reads of happy owners who may be justifying their purchase makes your opinion any more valid than mine. In fact my experience with more GM trucks than I care to count and nine years with my 2012 Tahoe may give my opinion more weight. I can tell you that comparing things like carpet, head liner and trim quality I prefer my 2012, the pieces just look more substantial. I've had zero problems including no loose light fixtures like I found in the 2021. I look for excuses to trade to the new model and find it hard to justify beyond a few electronic gizmos, a modern exterior and a little better ride but all new vehicles drive, well, like a new car.
I may end up ordering a 2022 if these troubling reports of build quality and parts failures decline but from what I saw and am hearing GM needs to up their game. And that is a common opinion which even a tech told me, "If you're not having any problems with the one you have you better keep it."
Why even the Chevy service department where I've been going has slipped. Last time I had an oil change they ran through oil and it was on the running boards and wheel wells. I thought it was water when I pick it up. There was a speck of grease on the inside of the door that if I hadn't seen it it would have been on my pants, the floor mats were smeared with greasy marks. Used to be when oil changes were half as much as today they would put paper on the mats and plastic on the seats. When I checked my oil level the oil didn't appear as clean as it should.
I used to go the service department in my home town until they wrecked my truck backing it out of the service bay. Tried them again 10 years later and they drug the fill hose across my open hood. The Tahoe was very dirty and it left scratches that had to be buffed out. You might say I'm very leery of even letting them touch my vehicles and at 66 years old I'm considering crawling under the Tahoe to change my own oil.
I admit some of this is rambling but I thought it useful to explain my point of view and that is quality and caring are on the decline and rather than accept it I choose to highlight it.
