Since I have owned this vehicle, my blind spot alert system has failed 3 times. In every occurrence, the warning lights in the mirror have been stuck in the "on" position. It has occurred at approximately 60k miles, 100k miles, and now 150k miles. In each occurrence, it was a defective sensor module due to the location of the module that allows water to get into the box. The blind spot light stays on constantly and no longer detects vehicle located in the blind spot of the vehicle. In every case, the cost of the repair was over $800 to replace the box.
Blind spot monitor module corrosion, second replacement in three years. Warning lamps on and side mirror alert lights remain on at all times causing a distraction at night.
For the second time, my blind spot alert system has quit working. The first time it happened, my vehicle was slightly out of warranty and it required a replacement of a part that cost over $800. The replacement worked fine for several years but has recently stopped working again.
The contact owns a 2014 GMC Acadia. The contact stated that the blind spot detection module malfunctioned due to water intrusion, causing battery corrosion. The vehicle was taken to an independent mechanic and the dealer, where it was diagnosed that the blind spot detection module needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA. The failure mileage was approximately 135,000.
2017 blind spot detection lights on in both mirrors. Both modules in rear bumber replaced. 2021 blind spot sensors on again and “park assist off” in dic with system not letting me turn back on.
Car shut off while driving. All electrical went out. Doors all locked while inside, key stuck in ignition. Started with side detection warning and within a few days car completely shut off while driving! huge safety issue! will not restart and still can't get key out of the ignition. Battery is fully charged but no power. Completely dead. There is a known recall on 2014 GMC Acadias for electronic module failure but not our specific vehicle though this seems to be the exact cause of our problems. GMC said they could not help?!.
