Special Coverage Adjustment N172097060 Side Blind Zone Alert Module Water Intrusion was issued for my vehicle. I took it in to get fixed and was told I was past the 6 year extension (May 2022) but under the milage (79,199). They told me the parts are on back order from GMC. This was on 04-03-2023. On 04-05-2023 I was driving my vehicle and the instrument cluster went partially blank. I lost my speedometer , tachometer and most of the other gauges. I had numerous warning lights on. The blinkers stopped working and I had no control of any environmental controls or radio functions. I pulled off the side of the road and shut the vehicle off. I tried to restart it, it started but even more things began to fail electrically. I shut if off again, tried another restart and now it would not start. I tried multiple times and could not get it to start. With the car off and the key out of the ignition, the heater control panel would stay on and the fan was running. I tried a few more times and finally got it to run but still had no instrumentation. I was less than a mile from home and tried to make it back. While driving I had no electrical control of anything and no way to determine my speed. I made it back, but now my vehicle will not start at all. With the key out it still runs the heater controls and fan. This is a dangerous situation not being able to control your vehicle electrical systems and being able to start your vehicle. This needs to be a recall, NOT a manufacture " Special coverage adjustment" that they know is a known issue and dont even have to parts to fix it.

Service side detection system warning started alerting me a few weeks back. This now is the second time that it has affected all the electronics in my car. Sending me random error messages and affecting the car from operating in a safe condition. Car would not start for 40 min. Once I finally got it started, none of the gauges worked and turn signals were not going off in the car. Luckily I was close enough to home, but this could be a serious safety issue if I was far from home. Car was not in motion as I started to notice issues and pulled to the side of the road. Noticed as I was pulling up to a stop and the brakes were not working correctly and started to get traction notices from the system in the car.

My wifes vehicle which is our family vehicle has had several reoccurring issues. We have brought the vehicle to the dealership several times and have not resolved the problem as it is still on going. The problem does not happen all the time but is extremely scary. While driving the vehicle will alert that you are about to have a collision but there is nothing in front of you just a vehicle to the side of you and will break on its own. This has happened numerous times but the dealership has not been able to replicate the problem. We also had service stabilitrak, traction control off and the service traction control lights come on the dash while driving. When these came on the vehicle started to shake horribly and the RPM's dropped to under 1000 while still going 40 MPH. I have also had on a few occasions the backup camera say vehicle guiding lines unavailable while reversing and while driving randomly the vehicle with say park assist off then disappear after several minutes. Just 2 weeks ago I went to start the vehicle and it said service theft deterrent system and would not start until I disconnected the battery and waited a few minutes to reconnect the battery and re-start the vehicle. We brought the vehicle to sheehan gmc in lighthouse point florida 4 times for these specific issues and received no resolution. After contacting gmc we received no assistance until I filed lemon law which then they sent an engineer who stated after a 2 hour inspection there was no replication of problems and vehicle is operating as normal. This vehicle is a death trap and not safe to drive my family in. I will not purchase another gm product.
