I have a 2015 Impala LTZ 6 cyl. with the blind spot warning and rear parking assist option. I am getting this message on the dash. The blind spot lights in the mirrors do light up when the car is started as usual and do not remain on. They do not react to approaching traffic. The left side mirror occasionally lights up while driving for no apparent reason. This occurs on 2 lane rural roads with mine being the only vehicle.
The dealer wants $96 just to "diagnose" the problem. What seems to be the problem and how difficult is it to fix.
Thanks.

IIRC a few of the forums members have had that problem, I believe that it was sensor in the rear of the car left or right. Moisture gets inside the sensor box and makes it swell. I would probably have the dealer due it. There are many issues like program the unit to the BCM and then clear any codes associated with faulty unit.

I have the exact same problem as qbymarty (thread starter) with my 2015 LTZ. It appears that this side detection system is pretty crappy and not very tolerant of splashing water and snow, which is not uncommon in New England. Is there some DIY test that can be don to tell if it is the sensor(s) or the control module(s). I'd like to not be at the mercy of the dealership telling me I'm looking at $1000-$2000 repair bill when $500.00 will fix the system. I've never liked all this modern electronic systems stuff on cars...all it does is help line the dealership pockets when they break. They are usually not easy or cheap to fix. An to make matters worse if this system is as crappy as it sounds, I'll probably be replacing these things a few time before I get rid of the car.

It happened to me, I took the car to the local dealer, they upgraded the ROM software to o the latest version and that’s it, it worked great.

Apparently GM has a program in place for the side detection modules. The special service bulletin is #N172097060 . If your Impala has less than 80K on the clock you should be good to go.

These modules are a common failure on the Acadia also. On the Acadia, the modules are mounted in a bad spot where water, weather and whatever other contaminants can get to them and eventually kill them. GM extended the warranty on them for the Acadia as well. The reason I mention the Acadia is because you can order the module on Rock Auto and install them yourself, no dealership trip required. Don't know if this the same for the Impala, but figured it could be worth looking into if the repair has to come out of your pocket.

2014 2LT, I had the message show up and called GM when I learned they would warranty the issue. The ran my Vin and said my Impala wasn't covered. Message went away and has not returned since. (It was a rainy night).

Just came from the dealer and they will not pay to fix my side detection system... apparently the program ended in October 2020... 😭😭😭 I called GM to complain and beg them to make an exception. I’ve been unemployed for 8 months due to the pandemic and can’t afford an $1100 repair right now. The service manager told me my car is not safe to drive until I get the sensor replaced. They also charged me $167 to diagnose the problem.

'How many miles do you have on your car? I'm assuming out of warranty as well

@stevenstark711 Hello, just wondering is your Impala newer? Mine is a 2014 with a detection issue. They just come on and off almost after already passing the vehicle, if they come on at all. I'm wondering if your Impala is newer because no matter what the service bulletin is I'm always told mine isn't covered or does not apply to mine. It's a 2014 Ltz 2lz with 61k.

This happened to me a couple of years ago I took my car in to the dealership they would not fix it I was a few miles over the warranty I had to spend about $2300 it's bullcrap they know their system is broke and wouldn't recall it until Made a complaint to the BBB but they only went up 70k mine is over that but I paid out of pocket now 2 years later its happened again don't know what to do I'm not paying any more money hopefully it doesn't effect the CPU because the last Time it shut down the whole car because of side detection system PLEASE help if anyone knows a more reasonable way to address the problem.
