WAS DRIVING AND VEHICLE ENGINE DEAD STOPPED WITH OUT WARNING. COULD NOT GET STARTED AND HAD TO CALL A WRECKER TO TOW TO GMC DEALERSHIP. WERE TOLD IT WASN'T THE FIRST TIME THAT THEY HAD SEEN THIS. THEY HAD A PART IN STOCK TO REPAIR IT. IT WAS DIAGNOSED AS THE “DRIVERS FUEL PUMP MODULE” .WAS SURPRISED THAT THERE WAS NOT A RECALL AS THIS COULD HAVE BEEN A DEADLY INCIDENT DURING RUSH HOUR ON THE ROADS IN MY AREA. WHILE RESEARCHING FOUND A RECALL ON FULL SIZE GMC 2021 SUVS FROM LAST YEAR (NHTSA CAMPAIGN NUMBER 21V739000) ! WHY IS THIS NOT BEING DEALT WITH ON THE 2021 ACADIAS? MY DAUGHTER HAS ONE SHE BOUGHT THE SAME DAY AND NOW I AM IN FEAR IT WILL DO THE SAME THING !!! NO INSURANCE ISSUES OR POLICE ISSUES. AFTER ENGINE DIED SEVERAL SYMBOLS INCLUDING ENGINE ICON CAME ON WHEN TRYING TO RESTART. ALSO RECEIVED AN EMAIL “DIAGNOSTIC ALERT” FROM ON STAR IMMEDIATELY : AN ISSUE WITH THE ENGINE AND TRANSMISSION SYSTEM IN YOUR 2021 GMC ACADIA HAS BEEN DETECTED. PLEASE SERVICE YOUR VEHICLE WITHIN 7 DAYS….

While driving down a busy road automatic braking engaged for no reason causing the Acadia to abruptly come to a dead stop in the middle of the road with nothing in front of me. Red collision lights came on at the same time as braking with no prior warnings. Could not get the car to move for a few minutes (when giving gas there were grinding sounds) then the braking system let up. Drove for another few minutes and it did it again. Called GM and WE had to figure out how to get the car to the dealership with a major safety issue. Took the car in and it was throwing B390F, U0184, B395A codes. When we received the vehicle back one of the codes was for a bad back up camera so the new rear back up camera view is so stretched you can’t use it to back up nor does it have the lines anymore. The rear view camera now has a view that is sideways. So I took the car back to the dealership and they had no clue how either could be happening and would look into it again. Did my own research and figured out there are two cameras on the tailgate so the rear view camera was reinstalled wrong. Sent proof of how I came to the conclusion and that I wanted the backup camera replaced/fixed also. Its been over a month and I cannot get my car fixed because I refuse to pay for a rental on something they messed up because they have no loaners. Well on 11/14/2022 my cars automatic braking system activated again only this time it stopped in the middle of the road and was not as dramatic as last time. The warning lights came on as the car was coming to a stop. This time I was able to move shortly after it came to a complete stop. GM dealership wants me to bring the car in somehow and I will be carless for who knows how long. There is also a safety recall for a cable for the backup camera with no parts available. I have an RO number and a complaint number.

My brakes are awful. They sqeak and sqeal constantly. I've taken it to Ken Ganley Buick GMC several times. Prior to that, it was taken to Nick Abraham BMC. The dealerships are able to duplicate the sound and problem over and over again. None of the dealership representatives are able to offer a solution other than paying out of pocket to replace the brake pads because the material the brake pads are manufactured from are falling short. There is no way the brakes are functioning the way they were designed. Thankfully, I have not been in a situation where I need to slam on my brakes but I am not confident that they would do their job in an emergent situation. I have a toddler and a new baby on the way. I purchased a big SUV with the mindset that it would keep my family and I safe. We have leased several GMC products over the years and have never had an issue like this. We will absolutely not be renewing our lease to prove our loyalty to this brand. The fact that I'm being told the only way to fix the manufacturers problem is to pay out of pocket and fully replace the brakes on my vehicle that is 1.5 years old with 28k miles on it, is absolutely absurd. We are willing to give GMC the opportunity to make it right. At this point, I'll be honest, I doubt anything will even be addressed.

The contact owns a 2021 GMC Acadia. The contact stated that while driving, he heard a loud rattling noise coming from the exhaust. The contact then stated that the RPM’s increased and the rattling noise became louder. No warning light was illuminated. The vehicle was taken to the dealer where it was diagnosed that the exhaust resonator failed the whole exhaust assembly needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 28,000.

We purchased the vehicle in March 2021 and within a few weeks, the rear camera started working intermittently. At one point, it displayed a black screen with a red warning triangle. The dealership ultimately replaced the camera and we haven't had the problem since.
