Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“The rear driver door popped open and won't close. The fan clutch failed 2 weeks after I purchased the vehicle. I thought the transmission went out because it was winding really high and not driving normally. Also the rear passenger doors on both sides have malfunctioned. The window on the passenger rear went out. I have not corrected the failures as of now.”

NHTSA complaint #10244088, filed 2008-10, 81,324 miles

“I have a 2003 Gmc envoy which developed a problem with the fan clutch going bad which an extremely large number of people who own this model and the trailbrazer had also. The dealership service manager told me that they were completely backed up for a few days and could not get to my problem but without even checking it out, he knew what the problem was and said they have had to replace many. I feel as though there should be a recall due to the high volume of this problem. …”

NHTSA complaint #10192643, filed 2007-06, 66,677 miles

“We bought this car used. Well before we bought it, they had the A/C fixed, due to it not working properly. Well the rear A/C and heat still do not work. Sometimes it comes on, and other times it does not. It does not give out heat at all in the rear. This is a real issue for us and many others with children. I have read plenty of other reports stating the same or very close. In all in all, this should be recalled and fixed. These cars are way to expensive to have this issue and not have Gmc step up to the plate and fix their issue.”

“One of the oil cooler line on my 2003 Gmc envoy is cracked and leaking transmission fluid on the cataylic converter. This is a serious fire hazard due to the extremely high temperature of the converter during normal operations.”
