I posted this from my phone earlier, but can't find it now. So I own a 2018 Compass Limited 4x4, nice looking car. But, I've had issues with the start/ stop function. The first time it happened a few months ago, it was due to computer upgrades. After paying for those $45 bucks for the first one and then like 5 or 10 bucks for the other two, it worked again, but at the dealer for multiple days. This time it occurred, it was determined to be a bad back-up battery. A new battery solved this problem. Next our location on our GPS wasn't working, it showed our location many miles from where we actually were. A new radio was installed and that solved this issue. I hope we're nearing the end of these gremlins from showing up. It's a pretty car, but...
