Expert Diagnosis Gets 2016 Chevrolet Traverse Blind-Spot System Fixed

Blind Spot System Problem

The wife of Mark, a Fairview resident, was having an issue with the blind spot monitoring system of her 2016 Chevrolet Traverse. The system was constantly alerting his wife that there was someone in her blind spot, even when no one was there. The alert icons in the mirrors were always flashing or constantly illuminated. This would also happen with the icon on the dash. There was also a warning message on the dash, saying “check blind spot monitoring system.” Talk about annoying!

Here is the weird part: The Traverse only had 29,000 miles on it and was already out of the factory warranty.

Mark called and spoke with Doug Reichert, our integration specialist. Doug asked Mark to drop the vehicle off for a day so ENORMIS technicians could properly diagnose the issue. Mark dropped the Traverse off one evening.

Blind Spot System thoroughly checked

Technician Ken Whiteman was tasked with figuring out what was causing the problem. Using the ENORMIS GM factory computer, he started by checking communication with the blind spot monitor sensors and found there was no communication with a blind spot sensor. That meant doing a physical/manual inspection of the system. Ken removed the rear bumper to inspect the system and found severe, heavy corrosion. (When corrosion of electrical components is involved, there can be all sorts of weird reactions in the vehicle.) The only solution for the severely corroded parts was replacement.

Parts ordered and problem solved

Doug ordered the needed parts for next-day delivery to lessen the amount of downtime for Mark. Ken installed the new parts and saved all the old parts for Mark. After the installation, programming was required for the blind spot monitor system. Ken test-drove the vehicle after the repair and verified that the blind spot system was working as designed.
