GMC Complaints

The manufacturer admits this defect can cause death but has no remedy and no estimated time for available parts. They also refuse a rental or loan vehicle in the meantime.

The contact owns a 2016 GMC Acadia. The contact received notification of NHTSA Campaign Number: 23V334000 (Air Bags) however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was made aware of the issue. The manufacturer was made aware of the issue. The contact had not experienced a failure. VIN tool confirms parts not available.

The OEM LED taillights can fail due to a manufacturing deficiency. A metal strip that connects the LED's to the cars taillight circuit develops a crack and interrupts current flow to the taillight LED's. The above is common knowledge to the car community and is searchable on line. Concerns: 1) If both taillights are failed at the same time the vehicle doesn't have any of the required visible markings, especially at night. 2) From an economic point of view, unlike vehicles that use incandescent light bulbs that are easily replaced when burnt out, these LED light assemblies have to be completely replaced to the cost of several hundred dollars plus labor which could/will lead to the neglecting of this repair because of the economics. 3) Unlike incandescent bulbs, LED's are should last much longer to the point of outlasting the life of the vehicle. This isn't the case when there is a manufacturing defect. In my case on 10/21/21 the defective taillight assemblies was replace under a defective taillight extended warranty agreement. I requested to have both replaced because of the odds of the second one failing. They refused. So when the opposite side assembly failed recently i was out of the extended warrant date resulting in a cost to me of $392.88 labor included. In conclusion, The well documented failure of the above taillight assemblies leads to vehicles being non conforming to FMVSS.

Carrier Bearing ( Hanger Bearing) broken off mounts. Bearing is mounted via spot welds. The spot weld were not done properly. Was driving at about 30 MPH slowing down when the bearing broke loose from the mounts. The caused the drive shaft to swing about hitting the floor boards. Breaking the universal joint and drive shaft came apart. There was less that 300 miles on the bearing. The truck typical hauls one bicycle. The truck was not used in any commercial function. I'm retired and like to ride my bicycle. I was very lucky in the that I was slowing down for a light. The road I was one is 55MPH. If the drive shat had hit the ground at that speed I'm certain there would have been a very serious accident involving many vehilces.

The contact owns a 2017 GMC Yukon. The contact stated that on several occasions while the vehicle was parked, the passenger’s side rear taillight failed to illuminate. The vehicle was taken to an independent mechanic where it was determined that the full assembly light kit needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the issue. The failure mileage was approximately 80,000.

After having simple oil and filter, and engine and cabin filter replaced at Alpine Buick GMC in Colorado Springs, CO, I received my vehicle back and noticed a complete difference in performance. It hesitates when accelerating, stays low in every gear, and bounces, and I mean bounces hard, when shifting gears, especially slowing down. When slowing down, as it shifts to the next lower gear, it almost pushes the truck forward against me pushing the breaks. Then, when feathering to accelerate slowly, it almost bounces back up to speed, hesitating until I let off the accelerator pedal a little, and it immediately shifts to about 1000 rpm in gear. I have to push really hard for it to go up a gear, and when it does, it has lost all power. My vehicle doesn’t run right anymore after my service appt. I have brought it to my hometown dealership and they say it runs fine and nothings wrong. But there is something wrong with it.

Like so many others, I have persistent transmission or drive train problems in my 2017 GMC Sierra. This has been documented on multiple visits and test drives with the dealer where I purchased the vehicle and to another GMC dealer. The first occurrence was after about 4,000 miles. A loud clunk sound occasionally occurs while shifting thru low gears and the transmission shifts very hard. To the point that the transmission hesitates between gears and then jerks me back into the seat. The selling dealer has witnessed this and tried various repairs (supposedly flushed and replaced the fluid, supposedly replaced an unknown computer component, etc). None of this helped. Now the transmission also hesitates and seems to slip during a downshift thru the low gears. The selling dealer finally told me "nothing is wrong with this truck, so don't bring it back again". I assured them that I would never be back, especially when I'm in the market for a new truck. GM should take note of this, also. Online websites show many posts of owners having this issue. And neither the dealers nor GM are even acknowledging a problem, let alone offering a solution. Unfortunately for me and many others, the value of this vehicle is impacted by so many complaints, no action by NHTSA and questionable practices by GM and their dealers. Buyers beware!!! The transmission in this truck is junk and you won't receive any assistance from GM or its dealers. The only hope for owners of this truck is for NHTSA to step up, launch an investigation and require a recall. This a known issue to owners of this truck, GM, its dealers and the NHTSA. It's time for all of them to step up and do what's right for consumers.

While driving at 70 MPH on the interstate approaching a bend in the path of travel the "service traction control" warning was displayed on the instrument panel display and just after that the electronic power steering stopped working causing a near collision with a vehicle in the adjacent lane. The local GMC dealership noted a recall for the 2015 Canyon model for the steering gear torque sensor cover assembly to be replaced due to corroded electrical connections. The number (15595) recall was not associated with my VIN but should be added as part of the vehicles in the recall as it is experiencing the same issues.

Nothing happened. GM sent a letter telling me that the airbag COULD rupture and call serous injury or death. I am not driving the vehicle.
