Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I got out of my truck, had left the keys in the ignition, walked over to get something off the ground and heard the horn blow. I walked back over to the truck to get back in and it was locked. I called on star and they couldn't unlock it so they had to send a lock-out service to unlock the truck. This has happened at least five times in the past three years, three in which on star had unlocked it.”
NHTSA complaint #10683376, filed 2015-02, 93,801 miles“About 2 months after we purchased our pre-owned 2009 Gmc Sierra denali we started having problems with the engine power and all sensors going off. The sensors start going off the stability control cuts off it says engine power reduced then doesn't want to shift and kills in middle of traffic. It will do it for a few days and then just starts working right again. So we never know when it's going to happen or where we will be. It's like it's not running on all cylinders.”
NHTSA complaint #10597321, filed 2014-06, 38,000 miles“I' m writing in too complain about the dashboard cluster on my 2009 Gmc Sierra. I see that a recall along with a lawsuit with this same issue was submitted. I have been going back and forth with Gmc on this issue since 2011. They stated it was a fuse and replaced the fuse , but my dashboard along with all the gauges go out every couple of months. I was told they didn't know what the problem was but obviously they did. This issue was noted after a class action lawsuit was filed. This is a very expensive fix that should have been taken care of when it first happened in 2011. …”
