2017 GMC Acadia Lane departure Problems

“The side blind zone alert system failed last year and caused the car to die and leave me stranded. The vehicle was still under manufacturers warranty and the dealership stated that the side blind zone system was faulty and replaced the module and sensors. A little over a year later and the system is doing the same thing. I will have to replace the module and sensors. This should not be my problem, Gmc has created a faulty sensor system and now consumers are having to dish out 700 plus dollars for the repair. There is a 'bulletin' that conveniently does not cover al VIN numbers mine included! …”

“It seems that all of these cars have a faulty side detection problem. Please check into it. It is a pain and is sad that it seems to happen to all of them. The side detection problem leads to other kinds of problems with the computers ... The light stays on all the time”

“The side detection alarms kept beeping regardless of any location on the road or in my own driveway. Now I have a service side detection module failure warning on the dashboard. Estimates on repair have been in the $800 range and after having spoken to many GMC owners, several have had the same problem. Some have made the repairs, others have not due to the cost.”

“I get a service side detection on my DIC. It used to work occasionally, now it no longer works. The sensors lights do come on when the service side detection shows up. Sometimes this alerts comes and goes and sometimes it stays until I push a button, in which it just reappears later. …”

“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.”
