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 have been trying to get this recall done for 1 year. I have placed 3 calls over this time and they say the part is on back order. This is dangerous as it is a recall on the driver airbag. A year is too long to wait. Please advise on what can be done. Dealership: GMC Thompson Raleigh, NC

This vehicle has a recall dated back to May of 2023. I have been trying to get the airbag for this recall replaced since then from the GMC dealership we purchased the vehicle from to no avail. I have been on the wait/call list since the recall date and still haven’t heard that my part is ready to be replaced. The airbags on our GMC Sierra were replaced so I do not understand why the long wait on the Acadia. I worry that if we do get into an accident, we will be badly hurt or killed if the airbags go off. The time frame to get this remedied is unacceptable.

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…
