Open the full vehicle complaint log (all categories)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.
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
