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,

We're glad to hear that the dealership has resolved this Blind-Spot Detection light concern with your Impala. However, we do apologize for any inconvenience associated with bringing it back into the dealer for another inspection. If you would like us to provide an additional layer of assistance as you continue to work with your dealership, feel free to send us a private message.

Have a great day,

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.

ouch. that's the cost of technology & more/newer electronics, i guess.

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.

i have diagnosed a few of these on a dodge 300. iirc they were $1500 each...so yeah, ouch.

where they were located was the problem. behind the rear tire under the fender liner....all green and corroded.

Same problem here

I have the exact same issue on my 2014 Impala LT v6. When the first sensor shorted out it started with a burning wire smell and then physical smoke coming out of my driverside taillight. Next my entire instrument cluster went dead. Car still ran but in low power mode. After Chevy told me it was not covered under my warranty and i had to pay 100% of costs i was forced to wait on repair. I mind you at the time i only owned the car less than 60 days. After disconnecting this sensor and replacing a fuse my car came back to life but still gets an error message on the DIC. Now my right sensor has nearly caught on fire and Chevy told me the same thing. They can not help and its not their fault. They made a module that is not waterproof and placed it on the inside of a bumper behind tires with no protection to keep water from splashing on it. They made a module and harness that does not have a properly functioning fuseable link. Otherwise the fuse would have blown before my car nearly caught on fire. Even after the fuse blew it still continued to smoke. I have lots of evidence that Chevy has put all of our lives in danger and won't own up to it. Chevy has recently changed the part number on these modules and made them more waterproof. This proves Chevy knows they have a compromise in their electrical system and this is exactly why i have a small claims against them. Ive attatched a photo of just how close me and my family came to being burnt. Contact me with any questions at plattsburghhandymen@gmail.com

My wife's car now has this problem 2014 LT passenger side. I tried to look under the bumper area to see the condition and there is a shield in the way for muffler ( the car is a V6) Has anyone replaced these units themselves? there was a post I saw that said the modules were right there a 5 minute job. I would replace both and the wire harness then have the dealer reprogram. I purchased the car new and it now has 52K on it. If I had to spend 1500k to fix I would consider trading the car in on another brand. I am very capable of doing what ever needs done I have 8 cars of different makes. thanks for help.

Hello, yes it is an easy fix but the problem is people are having this same issue 6 months to a year down the road. The second issue is the cost of these modules. Chevy should be responsible for replacing these for free considering this is not normal wear and tear. These modules are a manufacturing defect and a fire hazard. All the new vehicles have them and chevy, GM and Ford are having a lot of negative feedback on these modules. So becareful because your next newer vehicle is surely to be using the same side sensing modules. Ive left mine disconnected to avoid further issues.

Hope this helps

So I can unplug the module. Will I have a continual check engine notification? And I assume u disconnected both sides.

That is what I did until I get the new controllers in

I have the same problem with the "service blind side detection system" reminder on the dashboard of my 2013 Cruze. Can I turn off the system using the onboard menus and have that reminder go away until I can get it fixed? Thanks.
It appears there is no word on a recall action.

A dealer (or garage) can turn the warning off using a code reader,
but the warning will just come back on after a while. (maybe a day or 2)

I wonder if applying RTV to the seams on the module would help it in being more waterproof. This would however probably void the warranty for those still in warranty.

Found this article pertaining to the Cruze and blind side detection.

I think there could be some relief on the way. Today I received a letter in the mail to make me aware that some 2014 MY Chevrolet Impala E vehicles may have a condition where the side blind zone message is displayed on the driver instrument cluster (DIC) due to water intrusion. It goes further on to say, If this message is ignored, in certain circumstances this condition may also result in the loss of driver interface functions such as cluster, infotainment /displays. chime and passenger presence detection.
It states Do NOT take your vehicle to your Chevrolet dealer as a result of this letter unless you believe that your vehicle has the condition described above.
GM is providing owners with additional protection for the condition described above. If the condition occurs on your 2014 Chevrolet impala E within 6 years of the date your vehicle was placed in service or 80,000 miles (130,000 km), whichever occurs first, the condition will be repaired for you at no charge. Diagnosis or repair for conditions other than the condition described above is not covered under this special coverage program.
It goes on to say if you believe your vehicle has the condition described above, repair and adjustments qualified under this special coverage must be performed by a Chevrolet dealer. You may want to contact your Chevrolet Dealer to find out how long they will need to have your vehicle to that you may schedule the appointment at a time that is convenient for you. This will allow your dealer to order parts if they are not already in stock. It stated to keep this letter with your other important glove box literature for future reference.

Yeah same;
also mud & snow covering the radar areas
will affect things...

lol since my dads car is a 2014 like yours,
the 6 years is almost up anyways!!

yea, I thought the same thing, like you said what's the point ?........ I may get an additional 6 months or so.

I got the letter. I figure i will let them do the work this time and after they are done i will try to seal it betterat the connections.

2019 Impala Premier 45k
 

After I bought the car in April, used with 45000 miles.
I noticed my rh light would stay on or it would disable the blind spot detection system. I took it back they couldn't replicate it. I haven't drove it much since I bought it because I drive my Wrangler in the summer. I bought this to commute to my job on interstate. This car has horrible blind spots and imt short. I have bad depth perception and this is my first full size car I had a sonic before this (traded it for my Wrangler). I love the car, especially the comfort, horsepower and speed but honestly it's blind spots make me feel uncomfortable. It's at a chevy dealer who sees the problem but unsure how to work on it as they've never seen it before... Story of my life.

i have heard of the blind spot sensors not working because of being covered with snow.
i wonder if the sensors are getting damaged from water/moisture?
