The car needs an PCM upgrade because it’s lit up a code in randomly situation. Causing the vehicle to lose the water temperature gage, power steering wheel assistance reduced and ac stop working, gmc is aware of the problem even issued a technical bulletin in 2018, but instead of inform the clients about the defective part, they want the client with this problem to pay to upgrade a defective PCM that came out from factory with problem. Note the power steering wheel assistance is part of the safety of the car. The problem always existed in the car, it toke me 2 years to find the problem.

The toe links on my vehicle are bad and needs to be replaced. They broke as I was driving. Almost caused me to lose control and almost wreck. Thankfully there were no other cars around. I see this is a recall for GMC’s but for some reason not my vin number. Not understanding why if I have the same problem on vehicles that were recalled.

Cars emergency brake locks up for no reason. Happened on several occasions but last instance burned out actuator and locked up calipers from just sitting on a hill with foot on brake. This is a huge safety issue when it locks up for no reason on a road. It’s stranded me at least twice because it’s hard to undue.

I have numerous warnings, shift to park, steering, cross traffic, this endangers myself and anyone else around me, i have read several class action suits involving these problems and it could cause my vehicle to pose a danger, I have taken my vehicle in to a certified dealer and they state there is no known recalls associated with my vehicle which is strange because GMC knows that there are thousands of vehicles having the same problem, did I buy a lemon? These problems are clearly manufacture related and in no way normal wear and tare. I should not have to compensate these issues when I paid near 40,000 for it

THE VEHICLE WAS STATIONARY AND DID NOT ALLOW ME TO TURN THE POWER OFF. SHIFT TO PARK MESSAGE WOULD NOT GO AWAY EVEN THOUGH THE VEHICLE WAS CLEARLY IN PARK. I HAD TO TRY 10-15 TIMES TO PUT THE VEHICLE IN OTHER GEARS AND PARK AGAIN AND TURNING ON AND OFF UNTIL IT EVENTUALLY TURNED OFF. THIS HAS HAPPENED SEVERAL TIMES AND IF I JUST LEAVE IT WITH THE MESSAGE THERE THE CAR EVENTUALLY DRAINS MY BATTERY. IT HAS BEEN HAPPENING FOR A WEEK DURING SEVERAL DIFFERENT OCCASIONS AND AM CONCERNED IT COULD DRIVE AWAY ON ITS OWN IF IT HAPPENS AGAIN AND I CAN'T GET THE MESSAGE TO TURN OFF.

FIRST OF ALL, THIS ISSUE IS BEING REPORTED BY HUNDREDS IF NOT THOUSANDS OF GMC ACADIA OWNERS. I RECEIVED THE "SHIFT TO PARK" MESSAGE MONTHS AGO WHILE IT STILL WAS UNDER THE 36,000 MILE WARRANTY AND THEN IT WENT AWAY UNTIL LAST WEEK. I GOT A "SHIFT TO PARK" MESSAGE WHEN I TURNED THE VEHICLE OFF EVEN THOUGH THE GEAR WAS IN THE SHIFT POSITION. THIS CAUSED A NUMBER OF SECONDARY ISSUES THAT ARE NOW COMPROMISING THE SAFETY OF THE VEHICLE. ONCE I AM ABLE TO TURN THE VEHICLE BACK ON AFTER IT DRAINS OR KILLS THE ELECTRICAL SYSTEM, I AM GETTING A NUMBER OF ISSUES. HOWEVER, THE ONES THAT CONCERN ME THE MOST ARE THE ROLLS EVEN THOUGH THE VEHICLE IS IN PARK, LOSS OF POWER STEERING, LOSS OF AWD, LOSS OF STABILITRACK, LOSS OF ABS, BRAKING SYSTEM ERROR AND POWER SURGES. THESE ARE THE MOST CONCERNING BUT I AM ALSO HAVING ISSUES WITH MY DASHBOARD, NAVIGATION, AND VEHICLE INSTRUMENTS. I CALLED THE GMC DEALER WHO HAD NO PROBLEM TELLING ME THE GEAR SHIFT BOX NEEDED TO BE REPLACED, NOT COVERED UNDER WARRANTY AND THEY HAD NO IDEA WHEN THEY CAN FIX IT BECAUSE IT WAS ON A NATIONAL BACK ORDER. WHAT REALLY DISTURBS ME IS THAT THERE ARE LAWSUITS GOING ON DEALING WITH THIS PARTICULAR ISSUE AND THAT LITERALLY IT COMPROMISES THE SAFETY OF THE VEHICLE AND NEITHER GMC OR THE NHTSA HAVE ACTED ON THIS. I WAS DRIVING TODAY AND REALIZED HOW DANGEROUS IT WAS TO OPERATE A VEHICLE UNDER THESE CONDITIONS. YOU CAN LITERALLY BE DRIVING AND THE VEHICLE HAVE A POWER SURGE WHICH MAKES YOU LOSE CONTROL CAUSED BY A MALFUNCTION IN THE GEAR SHIFT BOX. I AM ASSUMING THAT NO ONE WILL DUE ANYTHING UNTIL SEVERAL PEOPLE ARE EITHER KILLED OR SERIOUSLY INJURED. THIS ISSUES HAS BEEN REPORTED ON MODELS GOING BACK TO 2017 AND HERE WE ARE IN 2019 AND STILL HAVE THE ISSUE. PLEASE HELP US, THIS ISSUE IS HAPPENING TO THOUSANDS OF DRIVERS AND IT IS NOT BEING ADDRESSED BY THE NHTSA OR GMC. PLEASE RECALL OR STOP SELLING
