I own a 2017 Impala Premier. The right side blind spot detection LEDs are illuminating almost constantly. The right side works perfectly. Not sure where the sensors are located but regardless of where the mirror is set the problem occurs. It's under warranty, took it to the dealer and they said since it's not throwing a code the system is functioning normally. Is there some adjustment or sensitivity control on this system? Has anyone experienced a similar problem? It's a dangerous annoyance in its current state. Thanks in advance for any feedback.

 

Hello Jgennello, I am a little confused, you said the right side is illuminating continuously and I assume you meant the left side works perfectly. If so, I had a similar situation with my 2014 Impala 2LTZ. I bought it to the dealer and they replaced a module to fix it. When replacing the module, I believe the new module has to be programmed to the car. Here is a link to the issue I had. https://chevroletforum.com/forum/imp...problem-81694/

 

Could be dirt under the car, setting off the sensor;
(this happens with snow & slush buildup;
but yeah, they can't do anything without a code)
