FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

Back up camera randomly stops working (black screen-completely gone, or blue screen). Dash will randomly dim on its own and does not go back to normal unless car is shut off and turned back on. adaptive cruise control will disengage for no apparent reason. stabilitrak will flash on screen but no other indicators or reasons; nothing happens with car. Occasionally the blind spot mirror lights will not light up when vehicle is present.

FORWARD COLLISION AVOIDANCE: WARNINGS

My front camera that detects the front collision and helps with adaptive cruise control just went dark. I thought maybe it would reset after turning engine off and restarting it, but it didn’t help. Not sure what happened.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

I bought my car [XXX] it had 7 miles. I loved my car. Then in January 2021 things just went crazy. It started with park light on. My forward brake assist warning didn’t work, my back up camera in and out . My braking and stability were on and off. Then weird codes like. Engine at half power, unable to shift soon and speed control out. Then if I hit a bump message went away and speed control back on. I’ve taken care into another GMC dealer because dealer I bought my car at , closed up and took off!! Took it to closet dealer. Not long after repairs same issues started! So many different problems all at once! I have been treated horribly during these issues by dealership and extended warranty company. Dealer had my car for 3 weeks ! They couldn’t figure out the problem. I sat there for 4 hrs sent me home told to come back for 9 mile test! Why in 4 hrs that wasn’t done. So again the unable to shift message back on! I get in my car it starts but won’t shift ! Dealer charged me 250 to tow to shop! When they said I’d be fine ! I had more issues again and again! I’ve been driving over 40 yrs no accidents. I bumped into someone during a huge traffic jam in Ohio! Braking didn’t work no warning even . I should speak to a lawyer and could explain more to a person on filing these complaints. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Milton, FL

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

While driving the vehicle goes into Automatic Braking. It has stopped me while I'm driving or it will make a loud scrubbing noise as if I've hit the brakes quickly. It has happened over 15 or more times. I've taken to dealership and they are not very responsive to check into the issue I am having. It is a danger to me if I am on the Interstate with vehicles traveling at a high rate of speed.

NHTSA complaint #11508507 — an unverified report by a vehicle owner.

Sewaren, NJ

LANE DEPARTURE: BLIND SPOT DETECTION

SIDE BLIND ZONE SYSTEM TEMPORARIALLY UNAVAILABLE message displayed in DIC, and system does not function. I can not rely on the system as it very often does this. This issue started on 12/08/2022. I feel that I am at risk of a crash as I rely on this system for blind spot detection. There are MANY forums that state that MANY other 2020 GMC Acadia's have this issue. I feel like this is a GM issue, and the consumer should not be left with the cost of any repair, if necessary. This is a safety risk and could result in death from a crash due to a failure of a safety system.

Suwanee, GA

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

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.

Kokomo, IN

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

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.

BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING

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.

Ray Township, MI

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

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
