We bought this car new. It has over 140,000 miles on it. We have made several trips to Alaska and back, over the Al-Can, pulling trailer(s), driving in heat and snow. It is super comfortable. We have had brake problems, but that's to be expected with so many miles. AC works great, front and back seat. There was one recall issue 3-4 years ago, don't remember what it was, and they fixed it. This is probably our 4th or 5th Suburban/XL. I've loved 'em all!
This is a nice looking SUV, but that is one of the only good things i can say. Bought mine brand new, and have numerous ongoing problems. Excessive oil consumption, throttle body problems, and battery issues. The dealers and GM don't know how to fix many of the issues. GM customer support is useless unless the truck is still under warranty. They won't even help the dealer solve the problem.
This is not the SUV to buy for reliability or long term.
Interior is ok
Solve the engine problems.
Improve customer service.
Very comfortable vehicle but many, many problems with all the little sensors plus the 5.3 liter motor has a major defect and burns oil. GM says 1 quart per 2,000 miles is okay but after 80,000 miles it burns double that. It will even fail inspection for a lean cylinder due to the oil consumption.
The services stabilitrack / traction control will also pop on for you on multiple occasions. The tires monitoring system always needs to be reset, the cruise control works only when it wants too and the vehicle used allot of fuel. They say 13c/19hwy but on average you get 14.9 total.
quality is poor and try contacting GM for help.
all the customer service reps are in either guatamala or Argentina.
