2021 GMC Acadia

Was driving when the vehicle engine completely lost power. Very dangerous situation in heavy traffic. Had difficulty pulling to the side of the road and ended up blocking traffic. Vehicle needed to be towed and is less than 2 years old with less than 10k miles. Diagnosis is failure of fuel pump control module. I see there is an identical GMC Acadia incident already logged by someone else and the dealer said they have seen this multiple times. After 1 week at dealer, they are unable to secure part for repair and don't know when they will. A RECALL was issued for other GMC 2021 vehicles for this exact problem. GMC RECALL N212332040: POWER CONTROL MODULE MAY CAUSE FUEL PUMP FAILURE. However this recall does not include the Acadia. The Acadia needs to be recalled as well before people are killed and the replacement parts need to be made available.

Vehicle has previously been brought in to GMC dealership at least 2-3 times for the dash turning on and off while driving. Started happening around 5,000 miles here and there. First took it in just over 7,000 miles as it was happening more and more frequently. It was last in for the issue on 2/6/23. The dash turned completely off WHILE driving going approx 45-50 mph, is not turning back on, unable to see speed while driving.

Taken from service report; customer states brake pedal some times sinks to the floor and brake fluid on driveway. Tech performed brake fluid check and found that the brake fluid leak is coming from the left front and right front caliper hose, caliper hose has rub marking, making contact with cv boot. Tech replaced the left and right front brake caliper hoses and performed brake fluid fill and bleed, rechecked the operation of the brakes-brakes are working as design Also on service report: Left front cv axle leaking, left front outer cv axle boot is torn, replaced the c axle assembly. Not on the report is that the service manager Informed me that I should not have driven the vehicle in but had it towed in.

The contact owns a 2021 GMC Acadia. The contact stated while reversing out of her parking space, the contact heard a squeaking sound coming from the brakes. The vehicle was taken to an independent mechanic and the brakes were replaced; however, the failure persisted. The dealer was contacted and stated that there was an upcoming recall and to wait for the recall. The manufacturer was contacted and stated that the vehicle needed to be diagnosed. The vehicle was not repaired. The failure mileage was 26,000.

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.
