Example complaints

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

“Intermittent electrical issues. Doors locks and windows don't always work. Sometimes when I shut my car off it dies. Like I can't turn it back on. Running boards don't go up, can't lock it, nothing. Dead. Then 15 minutes later it's fine. Sometimes when driving, it's like it's cutting out, not getting enough power or different warning lights will randomly flash. I just never know when it's going to be working properly. I'm just afraid something will happen while we are driving. We also use the yukon to tow a trailer. I need to be able to depend on it. …”

“The rear passenger door does not lock or open with the remote or front drive door switches. Turns out that the lock actuator has gone bad and has to be replaced. My son is 4 years old and due to the fact that we can not lock the door from the front - he opened the rear door while car was driving . Luckily he was in car seat. This could pose a serious problem for parents with young children. While the car was under warranty the same rear passenger door side lock actuator was replaced 3 times. Unfortunately the car is out of warranty and the problem continues for us. …”

Approximately 1 year later, the drivers side rear passenger door lock actuator failed requiring one to manually activate the door lock each time.

Now. 2 weeks ago, the passenger side front door lock actuator no longer works. …”

“Just brought to my attention the recall on the Gmc silverados. I have been having the same issue on my Yukon Denali. I purchased a car in december of 2016. And I've had at least eight or more incidents. Of the car either not starting or shutting off for 3 to 5 seconds at about a 15 mile an hour turn. I feel as though my vehicle could be affected the same way as these are. I would like a remedy to why my car shuts off during a low-RPM turn. When the car comes back on all gauge lights come on for a brief second. …”
