Front Passenger Brake Hose Failure by Crimp
Check engine light came on, reads reduced power and is causing problems accelerating
My check engine light came on along with my traction control light, and "Reduced Engine Power" popped up. This is connected to a recall on this vehicle for a connector at the throttle pedal.
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 a...

Eventually couldn't get it to stop. Per dealer "Possible intermittent failure of the park switch in transmission shift control. Need to replace transmission shift control assembly." Car out of warranty, cost was $726.21. Dealer ...
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 D...
@ 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 contact owned a 2018 Buick Regal Tourx. The contact stated while his daughter was driving approximately 55 MPH and under wet misty road conditions, she saw that the vehicle ahead had stopped, she depressed the brake pedal in a panic stop. The vehicle did not stop and crashed into the rear of the other vehicle. The contact stated that his daughter did not notice any warning lights being illumin...
The contact owns a 2018 Buick Regal TourX. The contact stated that the driveline rear differential unit was leaking fluid onto the garage floor. The vehicle was taken to the dealer, and the dealer replaced the rear differential pinion seal. The manufacturer was not made aware of the failure. The failure mileage was approximately 27,483.
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.
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?
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 FA...

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).

Component: Air Bags:Frontal:Driver Side:Inflator Module
Opened 2021-09-17
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited.
