2019 GMC Acadia

Unknown My 2019 Acadia Denali has/is been repaired 6 times in 1 1/2 years for engine oil leaks , has had transmission repairs twice , radiator repair and replacement. Also suspension warranty work as well . I feel the oil leaks is and has been excessive and dangerous due to no warning lights never displayed to alert me to check oil

Last week, the coolant gauge , on our 2019 GMC Acadia, was reading below "C".... The "Steering Assist" warning was disabled on the on-screen display and the Air conditioning stopped working. Took the car to a mechanic, who read the codes.... Mechanic stated that all symptoms were based on a defective GM thermostat. The thermostat was "stuck-open" causing the "steering assist" to be disabled as well as the A/C from being disabled as well. It seems GM has updated the part since when the series of Acadia were manufactured. After getting it repaired, at of our pockets, we researched and noticed that thousands of other GM Acadia owners had the same exact 3 symptoms: (1) malfunctioning coolant reading (2) "Steering assist" disabled (3) a defective ("stuck-open") thermostat..... Symptoms were exactly the same for all parties involved. We have owned many vehicles never had a thermostat fail before 65k Miles.... It became a safety issue since the car disables the "steering assist" based on the thermostat being stuck open. Contacted GM corporate which stated unless a recall, there would be no compensation. GM needs to make it right for the thousands of GM owners whose car has the 3.6L engine In short, this is a major issue since the car's steering system is NOT working correctly We would like a recall to be initiated. Thank you.

Component: Shifter Assembly & jumper harness Safety concern: Can't turn off vehicle - Carbon Monoxide poisoning, physical safety when parking not at home, as I would have to leave vehicle running... Message in dash was present when I brought vehicle to dealer. Dealer also replicated No inspection other than dealer. Part returned to me. Warning message has been coming on for past 60 days or so, progressively getting more frequent I receive a 'shift to park' message in telltale after I have shifted to park. At times, vehicle will not shut off until shifter is manipulated for several minutes. I have concerns that I cannot park vehicle in garage, if I cannot shut it off. GM is well aware of issue, but has yet to recall them. Dealer actually had replacement shifter in stock for a same day repair.. I was charged $778.98 for the repair, and GM's customer assistance center response to me simply was to file a complaint with NHTSA. My wife does not feel safe driving, as there is no guarantee vehicle will turn off. Dealer replicated issue when I brought to dealership. Dealer has replaced part and has them. Warning lights only appeared when problem reared itself, initially began about 60 days ago, but is not occurring on approximately 2 of 3 shut downs.

My 2019 GMC Acadia with 33,000 miles on it started to give me a notification to "Shift to Park" even though I had already shifted the vehicle into park. A "ding! ding! ding!" alarm wouldn't go off and the vehicle wouldn't turn off unless I repeatedly changed the gears until it read it was in park. This went on for a few weeks and got progressively worse. I read on a GMC forum that the vehicle could slip out of gear while driving and potentially cause an accident. My mechanic found the shifter assembly to be defective and replaced the entire Gearshift Lever Assembly. He said there was a plastic piece in the gearshift that snapped off and said this was an issue in the older models but thought GMC had fixed this issue by 2019. Unfortunately, I was past my 3 year / 36K mile warranty and had to fork over $1300 to have it repaired.

Our 2019 was repaired back in 2021 for a "shift to park" issue. This same issue is happening again after 2 years of being repaired. We see that there is a major issue with GMC vehicles and there have been recalls for this same exact issue. GMC Coleman, Lawrence NJ is refusing to fix problem under a recall. We would like this to be covered or reimbursed.
