I know this has been discussed before but I'm not sure if there was ever a resolution to the issue. Yesterday for the first time my driver's side blind spot detector activated when there was no vehicle near me. It would go out and then come back on randomly. When it is off and a vehicle approaches me it seems to work like it should. But it's frustrating when it is on and it shouldn't be because you lose the value of that feature. Haven't called the dealer yet but wondering if anyone else had the issue and determined the cause. Mine is a 2019 Blazer.
