AutoNation Buick GMC Park Meadows

Master cylinder, brake assist failure. HVAC control unit problem with backlit buttons. Broken sun roof slide latch. Initial review with service advisor didn't identify Vehicle Protection Plan coverage. After getting estimate to repair everything I reviewed my Protection Plan I discovered all work should be covered. Service advisor then contacted Plan Administrator and all was covered. Picked up vehicle and discovered HVAC control unit wasn't replaced. I had to bring the vehicle back to Autonation to complete the work. Also wiper blades were supposed to be replaced but tech evidently forgot. Service advisor comped the blades and got installed when I initially picked up the vehicle. When the vehicle is running well I like it but I have had several significant part failures since I purchased the vehicle. I'm concerned about taking the vehicle on the road given the issues I have had. When I purchased the vehicle the finance person sold me the Vehicle Protection Plan as covering the "electronics" associated with the dash. My fault I didn't read the details of the plan which turns out to be a very comprehensive Protection Plan. April 2022 while travelling I got an error message on the dash board advising me to shift into "Park" and when I shut off the car an alarm sounded. Vehicle was in "Park". We were in Columbia MO and I contacted Bob McCosh GMC to resolve. Bob McCosh GMC was great getting my car diagnosed that same afternoon and getting us back on the road. The vehicle was 3 days out of the 36 month warranty. Bob McCosh GMC went over and above to contact GMC and got the repair covered with a $25 copay. After returning to Colorado I took the vehicle thru a car wash with an undercarriage wash. Immediately I encountered multiple error messages: 1. Parking brake needs service, 2. Steering assist may be reduced, 3. Engine power may be reduced. Steering assist didn't seem affected but engine power was reduced for brief period. I took the vehicle into AutoNation Park Meadows and they found code P2138 for the accelerator pedal and replaced with a charge to me of $584.76 but I advised the service advisor of my Vehicle Protection Plan and she only charged me the $100 deductible. Upon running thru the carwash again I encountered the same issues. Returned the vehicle to AutoNation Park Meadows and the couldn't recreate the problem. I suspect something associated with the repair and Bob McCosh GMC was the problem but I can't verify that. I now don't allow the undercarriage wash to spray the undercarriage. There was no charge for this visit.
