I took my Buick enclave into the gmc dealership two years ago for an service airbag light that kept coming on. They sent me home twice saying it was just a computer issue. Now this recall is out and I asked for my car to be serviced as I'm a mother of 4 and can't stop driving my vehicle. They said that the part isnt out yet and nothing they can do. I'm having to drive a dangerous vehicle around with no help from gmc.
While driving at highway speed, Service Traction Control/Stabilitrak warning comes on. Vehicle slows and if driver attempts to accelerate (using accelerator pedal), it causes severe lurching of vehicle. This makes the vehicle basically undrivable while in the middle of traffic. You must use emergency measures to pull over (potentially across multiple lanes) off the road and while trying to do that, you are in a very high risk state of being hit. The problem is reproduceable. The manufacturer and dealer service centers are aware of this problem and it has been reported by many owners of GM vehicles since at least 2010. Search the internet and you will find hundreds of incidents being reported.
I started my car at a CVS parking lot. When I made a turn, the car was out of control and I couldn't stop or turn the car. My car hit other three cars in the parking lot and finally stopped. The OBD-II code check later indicated a "Engine misfire detected". I once got a recall letter from GM for the following issue. Not sure if this accident is related to this issue. "Inoperative purge solenoid that could lead to excessive fuel vapors entering the combustion chamber from the fuel tank. This condition could result in no start, idle stall and possible drivability issues such as hesitation." The good thing is nobody got hurt in this accident.
On 3/21/18 I was pulling out of a gas station to head to work. My traction control light lit up as well as my engine light. Warnings went across my dash stating "traction control off" "service stabilitrack" "engine power reduced" I couldn't go over 40mph. I made it back to work. After work only the engine light was on. The next day I drove it and by the afternoon the engine light had gone off. This morning, 3/23/18 I drove to work without any complications. Due to weather we closed our office early. I pulled out of the parking lot and my traction control lit up as well as my engine light. All three warnings went across my dash again and this time I could not go above 20mph. I made it home with my flashers on. Once I got home I let my car sit for a couple hours and then took it around the block. Again only my engine light was on. We will take it to the shop once the weather clears.
