2017 GMC Acadia Driver Assist & ADAS Problems

Every time I park it show up “ shift to park and it takes long to remove the code. battery keeps dying because of it since the car won’t turn off all night.

Side Detection Malfunction Message on Dash. Blind spot and cross traffic alerts not working. Vehicle has a blind spot on the driver's side and without this alert, I have found that vehicles appear to not be there but actually which causes issues with merging traffic and lane changes leading to potential collisions. Dealer replaced the side detection modules under warranty and special policy because of water intrusion into the modules. This exact same symptoms and parts have occurred and replaced 5 times, and a 6th is currently needed. All work was performed exclusively at GMAC dealer and vehicle is accident free. GM issued a special policy that covered this specific repair, and the vehicle now needs to it done a 6th time and GM has refused to assist saying vehicle is out of special policy. I have requested that GM inspect the vehicle but no response. I contacted GM and they declined assistance. I currently have the feature turned off because it was providing an error message on the dash and false alerts. I don't believe that GM actually has a long-term fix for this safety issue. Original Set of Sensors - 0 Miles - 2nd set of sensors - 5,894 Miles - 2/2018 3rd set of sensors - 17,078 Miles - 5/2019 4th set of sensors - 32,546 Miles - 4/2021 5th set of sensors - 45,463 Miles - 3/2023 6th set of sensors - 64,335 Miles - 3/2025

As i am driving it flashes the warning sign like if I was going to hit another vehicle when there is no car in front of me, this has happened since I purchase the care 1/2024, this has happen around l7 to 8 times already.

The contact owns a 2017 GMC Acadia. The contact stated while driving at approximately 5 MPH, the vehicle experienced phantom braking. An unknown warning light was illuminated. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was 114,590.

Service side detection system warning is on and upon investigation and diagnostics it has been widely reported as a common issue that GMC only chose to address for a select number of vehicles. I have 93k miles and there is a service agreement to 80k. Others have indicated that it not fixed it can send bad signals to circuit board causing battery failure, information system failure, dash light failure and headlight failure making this a safety issue is something like this occurs in the dark. As a result I am concerned for my safety and am frustrated that GMC is not required to fix this issue.

While operating the vehicle I stopped at a red light that was on a hill and the emergency parking automatically came on twice. I could not move the vehicle. It took about 15-20 minutes to finally turn it off. This has happened twice.
