I have a 2015 Chevy Impala 2LTZ. I live in the Northeast where it can be cold, raining, lots of mud and road salt. A couple months ago my vehicle began giving me a Service Side Blind Zone warning . I looked it up in the forums and it seems that these SBZ sensors can malfunction if covered with mud, dirt, salt, OR if the sensor modules connector attaching them to the electical system and car gets wet. Sounds like a Chevy design problem. A couple days ago I get a letter from CHEVY telling me that I should bring the car to a dealership to be checked and if the issue is water damage to the SBZ sensors/modules they will fix it free of charge. So I bring the car to a dealer and they tell me the issue is not the sensors or the sensor modules but a problem with the from camera. I was told a technician did a scan and got codes B101D and K109. Does this make sense to anyone? Does the front camera have anything to do with how the SBZ sensors or modules work? I'm concerned I'm being scammed here for some unnecessary repairs. Any way to tell if this dealership is being honest with me?

B101d on the Impala is a dead battery code. K109 did not show much out there, but did show something GM related to front camera.

I have a 2014 same exact ltz2. Had the problem just out of warranty. I did the same research and determined that I had to replace the blind side sensors. They are on each side of the rear bumper. Lay down under the car at the rear bumper and you will see it. It’s slid into its holder. I have a code reader and called the dealer for input after getting the codes. I don’t recall which ones. The tech informed me that the issue was those sensors. I was told to also replace the wiring harness as well because it shorts out too. This harness is also connected to the rear back up warning system, which are those round discs in the rear bumper. I removed my bumper skin to access all of it. I removed the sensors and they were both swollen and water logged. They were my problem. Once replaced, you have to have the sensors reprogrammed. Without labor I spent 600.00. Problem was fixed and I kept all paperwork and got my letter from GM as well. Needless to say I submitted my Paperwork to GM in Detroit. I bet your getting the run around because the typical bill is 1000.00. GM sent ou

Did you try laying down and reaching up inside your rear bumper? Mine was filled with handfuls of wet rocks and dirt from the road I was totally disgusted with the lack of thought put into this type of obvious design flaw! There are to many to pick one but I’m willing to bet the dirt build up had something to do with the failure of the sensors!!

Thanks. Went back to the dealership and asked them to show me ANY documented info that says the code they gave me are related to the Side Blind Zone Alert failure. They kept sending people to talk to me and after about an hour I spotted the owner of the dealership. I went and had a chat with him. He called the service manager in and asked a simple question "Can you show this gentleman where you got the details of the diagnosis? You should be able to get some document from the manufacturer. If you can't we need to give him his money back" So, I got my money back. The next day I got a letter from the manufacturer explaining that these Side Blind Zone Sensors can fail if they get wet. I should take my vehicle to a dealership and if moisture is the problem they will fix/replace them free of charge. So another local dealership determined moisture was the problem and agreed to fix them for free. The problem is that the parts have been on backorder for over 3 weeks. Apparently CHEVY agreed there is a design flaw they need to fix but I wonder if they have any REAL intention of fixing vehicles with this problem. No one can tell me when parts would be available. Turns out the first dealership were just a bunch of liars looking to exploit another customer. They didn't have the parts to fix my vehicle either hence the story about the front camera that made no sense. Anyone got any suggestions or a phone number I can call to get some movement/resolution on this. Clearly car manufacturers care about profits and not consumers or consumer safety

You need to relax! The time to get the water tight modules in the parts system will take time. The fact that GM is taking care of the problem through warranty which probably the part supplier is actually eating it due to their piss poor design.

Complaining will not help you at this time. Please wait 3 weeks and then call the dealers parts depart manager and ask him to get a time frame on when the parts will be available.

Bare in mind, that the module may fit other GM vehicles.
