“I just bought a new 2021 Buick Enclave and there is a noise coming from the windshield or the window. Sounds like my window is cracked. However, when I try to let up the window, the window doesn't move and sound is still there. The noise is there from about 45 mpg and up.”

NHTSA complaint #11398571, filed 2021-03

“The trunk latching system malfunction even when it is set to OFF. When the vehicle is off or running it will open automatically then will not shut unless you turn the car on then shut the car off put on lock then unlock the car. While driving short distances the lift gate will open enough to trigger the alarm. I have woke up my trunk is open. It is safety for me and others due to exposure of material in trunk falling out. Safety for me sitting in car this happens all the time. I have called the dealer they want to charge $90 hr to diagnose and fix it.”

“The catalytic converter has been replaced 3 times. The flex pipes has been repaired and replaced 4 times and the exhaust pipes has been welded on 5 times. The back tail pipe fail off while driving and had to be welded. The exhaust on this vehicle has given me many problems.”

“This vehicle has an auto stop start feature that the dealer refuses to override. The problem is that if you are stopped to make a left turn, the engine stops. When you need to go when there is a break in traffic, there is a hesitation to get going just when you need instant power. Also at stop lights or signs you tend to keep tapping the brake to keep it running resulting in a dangerous situation. Also if you are stopped and forget and get out of the car, it can start up and run into something. I just want the ability to disable this dangerous feature.”
