For many years I was a GM guy, and that's all I ever bought. I don't keep them past 100k miles, but never had any major problems with any of them. My wife's 2010 Malibu LTZ is a really nice car. It handles well, is comfortable, gets great mileage and has just about all the bells and whistles that were available at the time. It was built right after the big US auto industry upheaval in 2008. It would seem like a lot of attention to detail and quality was put into it. I don't know why there were so many issues with Enclaves built around that time. Different division?
In 2011 I bought a 2012 Grand Cherokee Overland for myself. That was probably the best vehicle I've ever owned. It had a nice ride, was loaded with options that even the Enclave doesn't have, was mechanically perfect, and still cost less than the Avenir. I traded it in for the Avenir last year. Normally, I don't buy a first year model change, but I wanted to trade the Jeep while it still had decent value. I also wanted a luxury class vehicle with the third row. So far, I have had no issues with the Avenir, but it has only 6k miles, and overall, I am happy with it. The cargo room is fantastic, it is comfortable, great suspension, has all the safety options and most other convenience features except the minor annoyances I've mentioned elsewhere. I'm hoping to get close to 100k miles from it, but if it starts having problems it will have to go. I have not seen any mechanical complaints about the new Enclaves, but there aren't many on the road. In fact, I've only seen one since I started looking a year ago. Dealers aren't stocking too many, probably because of the price point. If GM has ironed out most of the issues mentioned on here then they will have built a nice vehicle. Time will tell. And if they correct the omission of features you would expect at this price, they will have an awesome one.
I just read that GM is laying off 4000 white collar workers. That doesn't sound too good for them.
