LANE DEPARTURE,BACK OVER PREVENTION

1 complaint

Rear camera and cross traffic warning system malfunctions randomly, working less than half the time. When the vehicle is put in reverse the system and camera often do not work and issue a notice that it needs serviced. On several occasions it did not warn me of a person behind my vehicle or another vehicle behind me. I have avoided accidents but the system is not working. I have been reading about it and it is common among this vehicle, many complaining that this is the worst rear collision camera on a car. The screen is just black, sometimes with grid lines and sometimes without. On the rare occasion the camera turns on the grid lines often disappear although they are not turned off.

RECALL NOT COMPLETED? The previous GM Buick Dealership I went to, appears they will not or can not confirm that the Buick June, 2022 Recall (Braking issue) work was done in October, 2022 at Key Chevrolet Buick GM in South Burlington, VT. I have contacted both the Dealership and Manufacturer (Buick) current Case # 9-10190079245 twice and Buick (Corporate) is trying to contact the Key GM Buick Dealership to confirm the Recall work has been done and if done, then remove the still pending Recall notice that is still showing the Recall still needs to be done.

@ 40,000 miles The Buick Regal Tour X is making a loud humming noise from shifting gears from the transmission and a noise near the engine, when slowing down to 5 mph, loud humming noise can be heard. I took the car to GM service department and the mechanic told me he couldn't find anything wrong. I told him Yet, Yet?? I want to be proactive on this transmission issue.

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?

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).
