What 2018 GMC Acadia owners say
Most recent owner complaints, unedited.
My 2018 GMC Acadia is having the shift to park error. Causing it to not park; or error it causing us not to be able to turn vehicle off or know if it's in park. It pops up multiple times.
Roof is leaking in vehicle without reason after seals and tubing replaced. Brakes lock up without warning!
The thermostat housing fails and is a known issue which causes the car to overheat and they said it will start of fire or shut down and loss of steering assist. The dealerships know about the issue and GMC does nothing leaving people with large repair bills or inoperable cars. the system won't let me upload my receipts here is the part #12678780 I was told by the dealership this is a known issue and they my emissions warranty only covers the thermostat but not the housing, but that they are 1 piece, playing games.....
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.
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.
Shift to park warning when parking and shutting down vehicle. Shifter is in park but will not shut off electrical system of vehicle.
Blind spot warning light is not working. There is a previous recall for this for 2014-2017 GMC Acadia Models for the same issue. The issue has not clearly been fixed with models after 2017
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.
