On 9/24/23, I was driving both locally & the highway in S. I., NY. Suddenly the Adaptive Cruise Control feature shut off & on repeatedly & kept flashing (Adaptive Cruise Control unavailable) almost causing an accident, then I pulled over and shut off the system. The next day on (9/25/23) I brought the car to GMC & Buick Dealership at 1855 Hylan Blvd, S.I. N.Y. 10306. After a couple of hours, the manager Carlos Mercado tells me they need to do further testing tells me to come back on 10/04/23. I arrive at 9:00am for my appt. After three hours, I asked him what’s going on? He tells me that there are two Modular’s in the vehicle & needs to be reprogramed & updated. He says the mechanic that was working on it can’t do it & to come back. I knew at that point I was being scammed. On 10/11/23 at 10:15am he comes & tells me the vehicle is ready. I go to the register tells me at first was $671.00. I said for what? It’s outrageous! He says oh it’s electrical. I asked him did you replace any parts? He says no. replace any wires? He says no. I said if this was a recall I wouldn’t pay for it because its a safety issue. So he must have felt guilty and says I give you a discount & the price now is $555.56. So I says to him this is a lot of money for this. He tells me it was labor. I said to him I have been watching the whole time that the vehicle would sometimes be in the service area & the parking lot with the mechanic hardly working on it. I said to him do you think I’m a fool because I’m a woman unaccompanied by a man you take advantage of me. So they would not release the car unless I pay for it which I did with a credit card. On 10/12/23, I filed a complained with GM for a full refund, and explained that the program was faulty & only need an update and I was contacted by Charlie from the Executive team on 10/17/23. Tells me he will reach out to the dealer. On 10/23/23 he tells me they can only offer $250 in reward points which I declined, because they know I wont use it.
2019 GMC Acadia driver assistance complaints
Page 2 of 2: complaints 11 to 16 of 16, newest first, as owners wrote them.
Vehicle refuses to turn off due to "Shift to Park" error being displayed. Vehicle also gives "Driver assist unabled. Drive safely" message and AC will not cool and vehicle coolant gauges will not work.
Vehicle will have a message on the dash that says “drive with care steering assist is reduced”, the fans will come on and stay on, and the temperature hand will quit working along with air conditioner. It has not been inspected, I am not sure if the steering assist being reduced could cause any harm to myself or others.
Tl* the contact owns a 2019 gmc acadia. The contact stated that there was an abnormal sound inside the cabin of the vehicle while driving with the windows rolled down. Additionally, the automatic emergency braking activated without driver input. The vehicle was taken to rancho grande motors located at 1404 auto park way, san luis obispo, ca 93405, where the contact was informed that the issue was common with similar vehicles. The automatic emergency braking failure was not duplicated. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure mileage was approximately 500. The consumer stated the dvd would turn on it. The dealer stated it could be due to a missing remote that was not included with the vehicle. The parking brake would activate independently. The check engine light was illuminated. The steering and engine reduced power the warning light illuminated. The headrest dvd player do not play through the speakers. The wireless phone charger was often inoperable. The second gear does the not shift properly. The dash and radio periodically lose power. The windows make a loud obnoxious noise when rolled down.
9 days after taking possession of my 2019 acadia, with less than 900 miles on it, it stopped working. The first time I had a problem I had gotten out of the truck to run into a store. When I tried to start it I was getting a message to shift to park. The electric was on, but the truck would not start. I called for a tow truck. The tow driver got the truck started and advised me to drive it to the dealer less than 1 mile away. While driving on a major road I lost my power steering and stabiltrak, making it feel like I lost my brakes. My experience at the dealer was horrible. They changed my battery and said they fixed the problem. I did not even make it 24 hours before having the same problem. The electric was on but the truck was not running. I was getting a message to shift to park. The truck was off and parked but the dashboard was showing d then p again. I called for another tow, and this time it was actually towed. This time I was told it had to do with the computer. Service fixed it and held onto the truck for a few days to make sure it continued working without problems. 6 days later they called me to pick it up and it didn't even make 5 hours this time. The truck was still running this time, but the electric was going crazy. Every light was lit on the dashboard. As I was driving it to the dealer, the speedometer was going crazy. I was driving steady at around 35 MPH and the speedometer was showing 1, 0, 5, 0, 30, 31, 6, 0, 5, 31, 32, 1, 0, 5, 0. (I have a video of this but cannot attach it).so that was 55 days ago and I still do not have my truck back because gm is supposedly buying it back. I have concerns seeing 4 other people on this forum alone with the same problem.
I turned the car off and it displays a message 'shift to park,' even though the car is in park. It doesn't allow the car to shut off completely. The engine turns off, but the electrical stays on. When we try to drive it, it is slow to accelerate and the rpms shoot to 4 and don't go down unless breaking. Finally the car will not accelerate past 55mph and the rpms stay at 4, with the engine being very noisy. This left us stranded an hour from our house because the vehicle is not safe to drive. Fortunately this occurred in a parking lot. We drove a few miles to try to get to our dealership, but did not feel safe driving.
