Owner reports
Selected complaints filed with NHTSA by 2015 GMC Acadia owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2015 GMC Acadia. The contact stated that while driving at 25 MPH, the instrument panel went blank before the panel began to flash when it returned. The contact then stated that several various warning messages began to appear all of which were related to the vehicle's electrical features. The vehicle was then taken to an independent mechanic where a code reader found no defects with the vehicle. Close to a week after the initial failure, the vehicle failed to start after multiple attempts as previous failure returned. Due to the failure, the vehicle was towed to an independent mechanic where it had yet to be serviced or diagnosed. Upon his own inspection and research regarding the vehicle, the contact linked the failure to the vehicle's BCM(Body Control Module). The dealer nor the manufacturer had yet to be notified of the failure. …
The contact owns a 2015 GMC Acadia. The contact stated that the automatic alert system anti-theft system locked up. The contact stated that the vehicle failed to start. Additionally, the safety sensors in the mirror and the rear of the vehicle became inoperable. No warning lights were illuminated. The vehicle was towed to the local dealer, where it was diagnosed and it was determined that the driver's and passenger's side mirrors, and reverse light sensors needed to be replaced. The vehicle was repaired on three occasions, but the failure persisted. The manufacturer was contacted and confirmed that there was no recall for the failure. No assistance was provided. The failure mileage was approximately 20,000.
The electrical wiring started a fire that destroyed the engine compartment. I was in the vehicle and barely escaped injury while pedestrians were walking by and could have been injured when an explosion occurred. GEICO is now investigating the incident. A Service Battery Charging System warning light displayed on the dashboard and heavy smoke began to emit from the engine compartment then, a small fire started and escalated to a full and life threatening condition.
Drivers side door caught on fire overnight. Burned up the interior of the vehicle and smoldered out. Windows were up, car was completely closed and locked. Still starts and drives. Door, seat, steering, ceiling , visor all burnt and melted to some degree. Seems to have been electrical.
Side Object Detection Indicator failure. This was a recall in 2019 after my system failed causing the entire electronic dashboard to go black while driving on the highway. I had no indication of speed while driving. Once I pulled safely off the road and turned the vehicle off, it would not start and needed to be towed. I had it fixed and within months GMC recalled the module kit due to poor design resulting in failure to protect the module from expected weather exposure. The module was replaced in 2019. Again, in 2023, exactly 4 years again, the Side Detection Indicator has failed, due to expected weather exposure which resulted in corrosion. GMC denied replacement because I have already had it replaced. GMC is unable to confirm the module kit placed on my vehicle was an improved design and was the same kit design that has been known to fail. …
2015 gmc Acadia, vin ending 7457,p2635,stuttering/hesitation and engine stalling when Arizona temperatures exceed 100* f , and mechanic advising that the condition corresponded to a known gmc issue for which they could not obtain an applicable corrective part / repair
2nd time AC compressor motor breaks and as is in line with the serpentine belt, all other systems including electrical and engine stop working. Poor engineering or other reason causing part to break down.
Vehicle was destroyed by electrical fire on December 21, 2022. It caught on fire after 'SERVICE BATTERY CHARGING SYSTEM' warning light displayed.
On 15 plus occasions, while the vehicle is stationary, in the parking gear and running, the front end will start to vibrate mildly, increase in intensity and then the traction loss light illuminates, a blinking engine light illuminates, "service stabilitrak" and "service traction control" messages appear. Then traction contol off appears, followed by an audible loud click and vibration ceases, messages disappear and lights turn off. Once while vehicle in drive and being operated on a roadway, I pulled right at an intersection to have this same sequence happen during driving, resulting in an almost complete loss of power and acceleration and a near accident. The sequence was identical and once the errors cleared the vehicle accelerated rapidly and forcefully. …
On 4/11/18 we took the car to the dealership for a side dtection alert. Was informed that the right side module needed replaced. We declined service due to cost of $628. 01/2019 we were have problems with the car starting. Last week multiple warning a messages started appear on the dashboard as the car was traveling and stationary. Took the car in for service and diagnoses was the right side detection model had severe corrosion and the left side model also had corrosion. Parts where not available so we drove the car home. Next day same issue with multiple warnings and alerts on the dash. My wife was able to make it home and after turning off the car it would not start even after charging the battery. Next day had the car transported to the dealership. After disconnecting the side sensor models, the car restarted and started functioning normal. …
