2018 Buick Regal Tourx SW AWD

The backup grid randomly disappears on the rear view camera when the vehicle is in reverse. This happens at least 1-2 times every trip, and sometimes as often as every other time I put the transmission in reverse.

WHEN AUTO START/STOP TURNS ON THE AUX PUMP THAT PUMPS COOLANT INTO THE CABIN TO CONTINUE TO HEAT MAKES THE MOST ANNOYING SOUND IN THE WORLD. GM STATES THAT IT'S NORMAL BUT, UNDER NORMAL OPERATION YOU CAN BARELY HEAR THE PUMP. WHEN IT MALFUNCTIONS YOU CAN HEAR IT DOWN THE BLOCK. BUT SURE, THAT'S NORMAL, OF COURSE IT IS. THAT'S WHY THEY CHANGED THE DESIGN OF THE AUX PUMP FOR 2020 BUT WON'T ADMIT FAULT. GM REFUSING TO CHANGE THE AUX PUMP, I HAD TO BUY IT AND DO THE WORK MYSELF. BUICK WARRANTY IS USELESS.

SIDE SKIRTS ON THE CAR ARE HELD BY DOUBLE SIDED TAPE. THE TAPE HAS BEEN REAPPLIED BY THE DEALERSHIP TWICE ALREADY AND THEY'RE STILL LETTING GO. WHY WOULD A CAR MANUFACTURER TAPE ON THEIR MOLDINGS AND NOT EVEN PUT ON A CLIP?

I OWN A 2018 BUICK REGAL TOURX ESSENCE THAT IS OUTFITTED WITH CONTINENTAL PRO CONTACT TX P235/50R18 TIRES. ON 11/6/2019, I FOUND THAT THE FRONT RIGHT (PASSENGER) SIDE TIRE HAD LITERALLY BLOWN OUT AFTER SITTING OVERNIGHT THE GARAGE. IT LOOKED LIKE TIRE HAD EXPLODED. MILEAGE WAS 7357 AT THE TIME. I AM 85 YEARS OLD AND I AM THANKFUL THAT THIS DID NOT OCCUR WHILE DRIVING AT A HIGH SPEED. CAR WAS PICKED UP AND REPAIRED BY THE ORIGINAL DEALER.

THE BACKUP CAMERA DISPLAY DOES NOT WORK PROPERLY. WHEN THE VEHICLE IS IN REVERSE, THE BACKUP GRID LINES DO NOT APPEARS AND THE WARNING TO DON'T APPEAR (ON THE DISPLAY). EFFECTIVELY IT JUST ACTS AS A CAMERA. THIS HAPPENS 80% OF THE TIME THAT I AM IN REVERSE. THIS HAS BEEN AN ISSUE SINCE THE DATE I PURCHASED THE CAR (9.29.18).
