The Automatic braking assist feature goes off at times when there is no threat of hitting something. It happens when pulling into a garage and also on the road while driving. There have been several occasions when this happened and the car suddenly brakes which could have resulted in being rear-ended. The car suddenly brakes even if there is no danger of running into a car (or garage) in front of me. It has not been inspected (yet) but it seems to be increasingly becoming more of an issue lately. There were no warning lamps or messages just the sudden, hard-braking and loud noise/buzzing it makes when it happens. There have been several occasions but I'm listing the most recent one below.
2020 GMC Acadia driver assistance complaints
Page 2 of 2: complaints 11 to 15 of 15, newest first, as owners wrote them.
Twice this vehicle has exhibited this behavior. The collision avoidance system would flash a red warning on the HUD showing that a pedestrian was in front of the vehicle with the vehicle brakes 'hard' engaging causing the vehicle to 'nose dive' even though there was no pedestrian in front of the vehicle. This is disconcerting to those inside the vehicle and potentially be a crash issue with any vehicle following to close behind my Acadia. This may be an issue with the sensors/software used by GM and thus a safety issue that should be reviewed.
Center console display does not start when you start vehicle. Stays blank! This happens occasionally. Sometimes restarting will fix, other times not. There is no rear view camera when this happens. Not sure what else is affected, such as backup warnings.
The vehicle was purchased brand new from Serra GMC in Washington Michigan in April 2020. It has been back to the dealer 5 times for the same issue, with another 4 times that it was not taken into dealer! Reoccurring issue involves the instrument cluster, All gages and visual indicators go to zero (speed, tach, fuel, temp, etc...) as well as getting a notification that the traction control is disabled, the ABS is disabled, cruise is disabled, and other electronic aid. This happens at highway speeds and to loose all function is a safety concern, it is not repeatable and happens randomly but it is the same issue. The dealer claims to fix the issue but it always comes back. GM has told me to accept the issue as its not detectable however this is unacceptable as it puts my family at risk. I have videos of the instrument cluster going to zero but its to big to attached - I can provide it if you contact me or tell me how to share it
Brand new vehicle. Purchased on 10/30/2020. Front collision keeps flashing a red light in the top of dash that shows up in windshield. This happens with no other vehicles on the road at random times. When the vehicle needs to stop or warn you it will not. It will just let you hit a pedestrian or another car. We noticed that the same thing is happening with the rear safety cross traffic.
