FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

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 thermostat stops working and my a/c stops blowing cold air, and driving assist stops and engine light goes on. It is a rampant problem among GMC Acadias with no reason or fix. Please advise.

LANE DEPARTURE: BLIND SPOT DETECTION

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.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

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.

BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING

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
