2015 GMC Acadia driver assistance problems

Filed Apr 22, 2026 · Driver assistance · IL

Issue: Repeated failure of safety‑critical module Description: The Side Blind Zone Alert system on my 2015 GMC Acadia has failed multiple times over the life of the vehicle. The system becomes inoperative and displays “Side Detection System Unavailable.” A local GMC dealer has diagnosed the issue as a failure of the SBZA module due to loss of communication. This failure has occurred repeatedly, approximately every two years, despite prior repairs and replacement of the module at my own expense. This is a safety‑critical driver‑assist feature, and the repeated failure pattern suggests a defect in the design or durability of the module. The system is unreliable and cannot be depended on for safe lane‑change operation. GM Customer Assistance has declined to provide support or escalate the case further, despite the safety implications and documented repeat failures. I am reporting this because the failure affects safe operation of the vehicle and appears to be a recurring defect affecting multiple owners of this model.

I was curious about recalls because I totaled my 15 Acadia SLT2 and when I hit the impact didn’t deploy airbags and I had no idea until after my accident that they were recalled!!! This incident totaled my Acadia caused my face to be slammed into my steering wheel, cutting me in 2 places and shattering my eye glasses. I now have a scar that looks like a 2nd chin from my impact to hitting the steering column! What should I do? I wasn’t or hadn’t received anything from GMC about this recall until recently and damage has already been done and I’m at a loss of tremendous amounts because my air bags could have saved $300+ glasses and doctors appointments etc…

I have a 2015 Acadia Denali with 95000 miles. I am getting the "service side detection system" message whenever I start my car, and the blindspot lights, cross-traffic detection etc. do not function at all. A"nationwide" problem I was told. I was also told that it would cost $800+ to replace if/when the part was available. I am really frustrated with this and was wondering a) whether this malfunction is a part of a service recall (given it is apparently a "nationwide" problem); b) whether the $800 replacement cost is accurate given that the part appears to be available for under $200 online; and c) whether purchasing this part will even fix the problem given that other forum members have stated that once this issue comes up, it continues to malfunction, even after the part is replaced. Very disappointed right now, particularly since this issue has been recurring on a number of GMC vehicles for at least 5 years.

A warning light is coming on telling to have the side detection module serviced. Brought it to a dealer and was quoted a cost of $1274 to repair. It is a complicated repair and if not repaired will affect other safety systems of the vehicle because all sensors are linked. I did some research and this issue is common for this make, model and year GMC Acadia. I would like some help getting assistance for payment of this issue - one that is common and represents a safety problem if not repaired. Issue is described as Side Detection Modules and Harness. If this is a common occurence and is a safety issue, a recall or other means of satisfaction should be offered by GM. Thanks, Brad Nylander 218 343-8780

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. GMC engineers need to reassess for a second recall as the issue is not resolved and could lead to devastating injury or death.

Service side detection system distracts me from driving causing an accident

2015, GMC, Acadia SLT. Rear brake calipers had to be replaced out of my pocket after rear brake calipers froze and locked the brakes in the middle of traffic. This almost caused a major accident in which lives may have been lost or severe injury sustained. The rear brake calipers were inspected by a mechanic. ABS, Traction Control and Stabiltrak warning lights illuminated. Had to have the vehicle towed four times due to rear brakes seizing. Vehicle was sold to me by Posner Park Chrysler, Highway 27, Davenport, FL who did not fulfill the promised repairs and lied to BBB but researching their submitted Used Car Inspection Sheet, they destroyed the rear brake calipers when installing rear rotors and pads and never did install the passenger side fog light assembly as promised after they claimed they had ordered it and held up vehicle delivery until the evening before my departure from Florida back to New York. They were deliver the vehicle by 11:30 am, August 17, 2021 but I did not drive away with it until 5:00pm, the clock-out time for all mechanics in Florida.

Every time I go to the gas station after filling up my truck with gasoline, my vehicle will not start up right away. I have to press the gas pedal lightly in order for it to start up. This just started recently.
