What owners say
Dash has cracked in 5 places the dash is also peeling paint. Also the crime interior handles the chime is pulling off and extremely sharp. My exterior door handles paint is falling off in chunks on all 4 doors. My drivers side seat the lumbar support broke 3 times.
I purchased my truck about 1 year ago and it had 32,00 miles on it, it now has 40,000 miles. Everything was fine with it until about mid-april. I was driving to kalamazoo to see my daughter on I-94 around 72 MPH with the cruise control on. I turned on my left turn signal to change lanes to pass the person in front of me and to my dismay my speed dropped drastically as the cruise control disengaged. This happened several times on the way to kalamazoo that day. It also got worse on this trip, sometimes the door locks would lock and unlock, all of the lights on the dashboard turned on and off and every time anything happened the speed dropped, which to me is a safety hazard and should be part of a recall. When I got home the next day, I called levalley gmc to take a look at my truck (where it's been serviced since purchase). When I explained the situation to them, they claimed they never heard of it. That's strange because if this situation is googled, there is a lot of information about what could be wrong. Lo and behold a day and a half later my truck was fixed at a cost of $1069.71 for diagnosis and 3 cables, all positive and negative battery cables. I consider this situation a serious safety issue. I sent a letter to gm customer service. Lou contacted me and left a voice mail with case number 8-4206988703 (6/4/18). I called customer service and spoke with toni also 6/4/18. Toni reviewed the case and asked what I was requesting. I told her that this is a very serious safety matter that should be addressed and I would like to be compensated somehow. Toni stated that there is no recall for this situation and there is nothing that she can do. I told her maybe there should be a recall and I again stated that this is a serious safety issue
Vehicle will randomly show a warning signal for stabiltrack turning off. Then it will cycle door locks up and down, turn on the air bag light, ABS light, and sometimes reduce power to 20 MPH. It will also kill the vehicle gauges. Numerous trips to the shop have failed to correct the issue. A quick google search of stabiltrack 2009 chevy/gmc will show a ton of hits. Due to the safety concerns of these critical systems powering down, this is clearly a safety issue. This occurs while the vehicle is in motion, which makes it more concerning. This issue started with 66k miles and has persisted. Vehicle now has 96k.
All door locks are inoperative. They will not lock or unlock the doors with either the key of the door lock buttons. Just found this website-hence delay in reporting, did contact dealership-cost of repair is astronomical
The dash on my truck has cracked by the passenger airbag and also by the instrument cluster behind the steering wheel. Online forums prove that gmt900 vehicles (tahoe, suburban, yukon, silverado, sierra) have this issue. The headlights keep blowing and have replaced them 8 times. This is a safety problem due to having to drive at night. Also both right side doors will not unlock and this is a major problem when you have a small child.
The power door locks won't lock and unlock. I have already replaced one door lock mechanism at my cost. Now a second lock won't function. This is well known by gm. They refuse to recall it. This is a safety issue. Gm needs to repair these door locks.
My driver's door lock actuator has begun working intermittently. This is the second door lock actuator on my vehicle to fail, the first was replaced under warranty and the gm mechanic told me they have replaced numerous actuators. The vehicle automatically locks all doors when driven and unlocks when stopped however the faulty actuator does not always lock or unlock. These actuators have a long history of being defective and gm is aware of it but refuses to recall the faulty actuator even though they have literally replaced thousands of these units. These faulty actuators are a safety concern because in the event of an accident a door could fail to unlock effectively trapping the occupants. The faulty actuators are also a security concern because they could fail to secure the vehicle allowing anyone access to it's contents.
