NHTSA Complaint #11437404 — 2015 BUICK ENCLAVE

Sunday at 11 ish am eastern time I started the vehicle to get grocery items. The mileage was approximately 68680. The tire pressure warning light and air bag light came on along with the alerts to service air bag, side view collision, tire pressure, parking assist was shut off. The radio began to randomly shut off and reboot and the lower controls (heated seats, gate lift etc.) would not work, also the turn signal noise would go in and out. Tachometer and speedometer were slightly impacted. Monday I stopped at the dealer after making sure the battery connection was good- there has been no fluctuation of power according to the gauge or even how the items are alerting and the fact my door panel buttons to lock and unlock were not working. They were unable to detect an error with their handheld device even though all those alerts were going across the screen. Appt set for 10/20 at noon to go on the big computer (and probably cost my car payment just to see what is wrong) Today (I only have one car and was not offered a loaner even though we agreed it was a safety issue) the traction control light came on and off, the speedometer and tachometer were greatly impacted, the rear camera stated it needed servicing, my liftgate will not work even using the rear handle and sounds like there may be impact in the drivetrain happening as the gear select icon stayed on R for over 500 feet driving forward. There was no hard start, cold day or jump given- also compass is not working either. The radio will randomly say communication system is not working/connecting which appears to impact my OnStar. I have seen other issues for this year online and very concerned what electrical item it is going to impact next. I have children (K and college) and it is bad enough I HAVE to use my car to get to work. This will happen in park or going down the road at 55/60 and every speed between.
