Sorry to hear about your childs fingers, but honestly, it could have been yourself or your grandpa.
Not everyones handles are bad (mine at 107,000 miles without issue), but if you are having issues, I'd just get them online and swap them out myself.
Exactly. 70K and I have a rough spot on one, but it's not peeling, nor do I have an issue with any other handles. I just don't touch all of my door handle and it's like it doesn't exist. I freakin' WISH my Yukon's biggest problem was ****** chrome handles.
So, you contacted GM to complain about a car that is now an old body style, which you bought used, at well over 100K, from either a first or second owner, and you're upset because your kid cut his finger on the door handle? If they want you to pay diagnostic to replace it, that's not unreasonable. You've only owned it a few months.
Would you complain to McDonalds that his french fries were too hot, and he burned his tongue, too? Or maybe to Stride Rite when he falls and trips because his laces came untied?
Call GM when you go into limp-mode and lose power on the highway, or when you're 100 miles from home and you can't get in your truck because it died overnight, or you discover oil pressure issues, or your throttle body goes out.
Buy new interior handles and call it a day. Shit happens when you buy a used car, get used to it, with the list of complaints you've written so far, you'll have a long road ahead of you.
