I have purchased a 2018 Chevy equinox. It was damaged on the back bumper (rebuilt title). The backup camera works fine but there is a side detection error that comes on everytime I start the vehicle. The shop replaced the entire harness however that did not fix the issue. I have read 1000's of complaints on this. My vehicle has 45000 miles. This is effecting my gas mileage as well as other safety features. I see this has been an issue in MANY GM models and it has been taken care ( special warranty) but not on a 2018 equinox as of yet. I want to report this problem and see if someone can look into all the other forums etc to see how widespread this really is. The light has came on a few times lately but only when I am parked and not going anywhere??? Thanks in advance.
