Blind-Spot Detection Problem

I was running some errands with my wife tonight, when all of a sudden with no prior warnings or troubles, the Blind-Spot Detection light on the RH mirror lit up continuously. This is on our 2014 2LTZ. At first it was on solid, then it appeared to change in intensity or brightness going from the normal brightness that the warning light would usually display, to about 1/3 brighter flashing at about the same speed a directional blinks. We hit the button on the dash to enable and disable this feature, but it made no change. We then stopped at the drug-store, shut the car off and the RH blind-spot indicator remained lit with the car off. We went inside, did our shopping and when we came out, the light was still on. I opened the owners manual and found fuse # 62 was for this system and I pulled the fuse out, with the car still off. The light went out. I waited a minute or two, then with the car still off, I put the fuse back in. the light came back on.
I don't want to be dealing with a dead battery on a cold winter day, so I left the fuse out, so it wouldn't run the car down. Any ideas on what to look at next with this failure?

Do you have snowy/slushy roads?
Is your car dirty?
Even the condition of the road can affect things.

it sounds like something minor.
even try disconnecting the battery for 15mins. or so & see if it resets itself.

Try switching the left & ride side fuses & see if it happens on the drivers side mirror

The sensor is behind your rear bumper cover, so if it is muddy/slushy, the sensor COULD just be covered with mud/dirt/ice, & just need to be cleaned.

Same as if you are driving in the rain, & water is splashing everywhere, it will set off the sensors.
That's normal & not much you can do about it.

I'm going to assume its weather-related...

& even try pulling the fuse, washing your car & letting it dry, & letting it reset.

Yes, we had slushy roads as we just went through a big snow storm. The car is pretty clean considering.

Hmmm, I left the fuse disconnected overnight and first thing this AM before doing anything on the car, I opened the hood and put the fuse back in. The light went on immediately. So something may not be powering down properly. I'll check tonight and see if there is anything messed up behind the bumper.

I just ran across someone with a Cruze with the same problem on another forum. It turned out their blind spot module shorted out and according to their dealer "created a backfeeding condition". They did mention the new module needs to be programmed in at the dealer....

I just got back from the dealer at everything is all fixed. The module that I previously mentioned (23133813)was replaced and took care of the problem. Worth mentioning is the fact that I also needed an inspection sticker, and since the dealer decided to take care of the blind spot detection first, when they went to program in the new module, all the emission data was erased which resulted in a failure for the MA inspection process. I had asked them to do the inspection first, but they insisted to do this repair first. So I need to go back after about 100 miles of driving when the OBD Readiness will be in a state to pass inspection.

Hi there Frank3,

However, we do apologize for any inconvenience associated with bringing it back into the dealer for another inspection.

Around the middle of January 2017, the passenger side blind spot warning light on my Impala stayed on consistently (even when the car was off). Then the "Service Side Detection System" warning light came on. I took it to the dealer the following day, and after an $800 bill (the car had 39,000 miles on it) everything was working fine. They replaced the module (#23133813). The service advisor told me it happens a lot in areas that have slush and snow - I live in Buffalo. Everything was fine until a couple days ago when the same thing happened on the driver's side. I love my Impala, but I do wish they would make electronics last a little longer than 3 years. Since this is more of a convenience type of issue, I will just ignore the warning light. I refuse to pay another $800 to get the driver's side fixed.

amlm517 - That's rough..... When I was looking to get mine fixed, I looked around, saw several on eBay that were a lot cheaper, but I would only look at a new/unused module. In the course of my looking around, and found that module part #23188813 replaces module part #22971841. I am still wondering if my Impala had the old 22971841 on it which may have had a problem and was replaced by a newer version with part number 23188813. Whatever the case you may be able to find a cheaper module, it still needs to be programmed to the car when installed.
