I received an error service "side detection system". Dealer says it needs to replace the side blind zone alert modules (part #84648920) due to water intrusion on the module. They say it can affect the entire dashboard, causing it to fail. The chevy Impala forums have many mentions of this issue with this car. There have been reports of smoke coming from these modules. Gm had issued a special coverage n172097060 in 2019 but only covers cars 6 years old or less and less than 80,000 miles. Due to the widespread occurrence of this issue, it should be recalled.

Blind spot module has corroded and failed due to water intrusion. The module is very poorly sealed and clearly would lead to corrosion, very poor design. Potential for fire from electrical short is extremely high.

There is a bad sensor I believe on my Impala- the passenger blind spot warning light is staying on all the time - even when the car is off.

Side detection modules failed due to water intrusion. Verified by lynch Chevrolet mukwonago WI service dept. No warnings. Just system failed chevy will not replace under previous service bulletin. Want me to pay for full replacement.

Side detector system.

51,000 miles. System has failed three times. First two covered by warranty. Not under warranty now. There are numerous complaints about this problem. It will now cost me up to two thousand to repair. Car is at risk of fire,failure to start and other major electrical problems. Dealer wants $140 to diagnose, I am afraid to drive this car.

Side detection system failing and will not shut off.

Started getting service side detection system warnings. Learned there has been a problem with this blind spot system. Gm fixed it until Jan 2020 they say expired and my mileage was too high v problem just started last week of Feb 2022. 134k miles on it. Everything ran great but there are warnings from 2 years ago of dangerous repercussions from this defect. They won’t fix it and we can’t afford to have them fix it. I never got any notice of the problem from gm.

There was a recall on the sbza in April of 2019 and we received a recall letter from gm, probably in July of 2019 but the recall was for vehicles with less than 80,000 and we had 83,000, so I never pursued recall thinking that we wouldn't qualify. We had the sbza-side blind zone alert system replaces in December of 2019, at a big cost to us of $1000, at local Chevrolet dealer. The new detection system only lasted about 15-16 months or March-April of 2021 before it started acting up again. When I called the Chevrolet dealer up to complain about the problem, they told me that there was only a 1 year warranty on brand new part and it being over 1 year old now, it was out of warranty!! arrgghh!! we left it at that and it didn't cause too much of a hassle as I turned off detection system, using car radio settings and we only had a message on dash, which we could turn off and live with as we didn't have another $1000, out of our pocket, to get fixed. Then in November of 2021 and onwards, the light on drivers mirror would come on, stay on or blink off and on but doesn't always stay on. Now as of February 26 2022, we are having many of the same issues and things happening, that we had back in 2019, where the car is hard to start, dash doesn't work properly along with many safety warning lights coming on the dash, sounds, speedometer not working, no radio, no turn signals, no hvac, windows don't function properly, etc, etc. It usually goes away, after 10 minutes or so, then is normal again, then goes berserk again, off and on. This is now happening more often each day and is a huge safety issue, esp with our daughter using the car now, to get back and forth to work. She has panicked each time this happens. We bought car with 72,000 miles on it back in may of 2018 and it currently only has 126,300 miles on it. We love this car otherwise as it's been a real great car but now with this stupid problem again and so soon, we are not sure what to do. Thank you very much.

It appears that my vehicle had a special coverage bulletin titled “n172097060 - special coverage side blind zone alert module water intrusion” this special coverage only covered vehicles for 6 years or 80,000 miles. This week I started experiencing problems with my vehicles side blind zone alert system. From everything that I have read it appears to be the same issue that led to the special coverage mentioned above being issued. However, my vehicle is now outside of the specified coverage limitations. I believe that it should still be covered as it still remains a safety issue. Regardless of how many years or miles have passed. Thank you.

This is the second time the blind side detection system has failed on both my vehicle and daughter's 2014 Impala. Gm is aware of this is a problem and issued a special program, however; it expired last year. This issue can also cause issues with other electrical systems. Spending $1500+ every 2-3 years for an issue that is a manufacturer problem is not acceptabe.

My blind spot light on my side mirror was flickering, and now it just stays on. I read online that the sensor in the bumper can overheat, causing a fire, but Chevrolet doesn't have a recall on it. I ended up shutting off the blind spot sensor option on my car. I utilize the sensors, especially on the highway when I travel. There hasn't been a warning light go on as of yet.

Side detection module has falled. . . Yes it is available for inspection. . . My wife got locked in the car on a 80 plus degree day and could not get out,doors would not open,trunk release would not open trunk so she could crawl there the back seat,sunroof would not open,power steering periodically feels like there is no power stearing, dash lights periodically shut off when driving. . Yes, morries forest lake Chevrolet and cadilac. Forest lake. Mn. . . No it has not been inspected by anyone but the dealer. . . There were no warning lights untill 51,000 miles or 8 months ago.

My blind spot warning system has stopped working. This same year vehicle was recalled in other options (I have a Impala ltz). Just curious why the ltz was not recalled? I don't imagine it is a different system.

When I drive down the road my blind spot detection sensor goes off and lights up in the passenger mirror. It lights up if there is or is not a vehicle in my blind spot and has made me swerve back because I think there is someone or something in my blind spot. I have looked into this problem and it seems that there can be other issues that stem from this malfunction. I have owned the vehicle since 2019 where I purchased from a certified Chevrolet dealer and was not informed of this problem. This problem started to happen about 8 months ago and I reached out to where I purchased the venicle from with no response back from the salesperson I purchased thru. I don't want to continue to deal with this dealership and not get a return call from them. I have not had any other dealership look at this problem but I really need to find someone that can and will take care of this for me. I don't feel safe sometimes when changing lanes or letting my girlfriend us my vehicle to goto the store, or even take her child to school or sporting events he is involved in. I have done some searching on my own and seen that Chevrolet knows about this issue but I still have not received any information about this problem that has been going on for quite a bit of time.

We are having issues with our bling spot warning system not working warning light stays on in mirror and not going off its seams gm mounted sensor module behind rear wheel which gets exposed to water and then corrodes and malfunctions this also leads to many others safety issues including shutting vehicle down while driving because other systems are connected to it cannot isolate there should be a recall thankyou.

The connector on the drivers side module is corroded from water intrusion. It is an identical condition as described in NHTSA recall n172097060. The dealer and gm claims this vehicle was not included in the recall, even though it is a 2015 Chevrolet Impala. They now want me to pay 1,000+ dollars to fix the issue according to the steps in the bulletin? if I don't get this fixed soon is it could disable my vehicle as explained in the bulletin. I purchase the car in November of 2019 which is 7 months after this bulletin was released, and because gm did not include the VIN number in their system it was never corrected previously. The connector in the images is damaged now because the mechanic broke it at the dealer trying to get it off from the internal corrosion. I also contacted gm directly and they said that my car was not included in the VIN range and that I could take the issue up with NHTSA at my own prerogative.

My dashboard reads, service air bag. Everytime I turn it on as of this morning. 6/23/21 @ 1pm central time. I've read about the recall on these models as well of air bags deploying and throwing pieces of metal at drivers. Cause of molded air bag housing.

Just received a message on the driver information center that says "side detection system" so I looked it up in the warranty info book and found only an instruction that said to clean the rear bumpers, and nothing else. Called dealer and they want $135 to diagnose and possible repair charge of $1100. Looked into common problems with others vehicle owners and found several with identical problems; also found a gm 'special coverage adjustment"" dated 4-1-19 covering the cost of repair but also found it was only good for years and/or 80,000 miles. My vehicle has 62,000 miles but is 6 months beyond the years. Is this not a safety issue? I would think so. So what can I do about this, as I understand it can cause significant other incidents with the vehicle, such as loosing the instrument panel indicators as well as issues involving vehicle headlight and engine shut down. Would like a response as soon as possible as I would like to get this taken care of ASAP. Thank you james m. Fox cell # 586-260-8527 June 15. 2021 p. S. This has been the best vehicle I have ever owned; up until now.

All instruments failed. After a couple restarts they came back on. Lane departure alert doesn’t work now. From a web search, I’m afraid it’s just the beginning. No, I haven’t taken it to the dealer; they charge for diagnosis. And it hasn’t been inspected. The problem doesn’t act up all the time. There are no warning lights, the system just fails. I have 50,600 miles on it. If you find what I’ve found in my web search, the cost of repair is staggering, especially for retirees. I hope you look into Chevrolet’s problem they’ve been having with the Impala.

Blind side collision monitor is not functioning properly due to faulty design which allows moisture to get into cabin where the monitor is installed. Causing the collision feature not to function properly and "service side collision" msg to show on the dashboard. I had this issue before and had it repaired by the dealer on 03/2019. The problem has since returned. But this time it's caused the functions on the dashboard ( gas, h/c and speed meters, digital monitor screen etc) to stop working where I can't tell if I have gas or my driving speed or anything associated with the dashboard info system, it blacks out. And now the alert light on the door mirrors continuously stay on even when there's no car on the side of my vehicle and even when the car is turned off. I took it back to the dealership and have been told that the collision monitor sensors again need to be replaced.

We are still having issues with this stupid sbza blind spot detection system, twice now, first time we had fixed, 2. 5 yrs ago now, at a $1000 cost to us, as mileage was slightly over the qualifying miles with recall letter we received prior to having both modules replaced. Those brand new modules only lasted 16 months or less and weve been dealing with same safety issues for about a year now, some days worse than others. Its a dumb flaw and needs to be addressed soon but we dont have another $1000+ to come up with!! people like us, who live in the snow belt areas and have to deal with road salt and corrosion are going to keep having issues with them, even though we keep our car as clean as we can!! its a pain in our asses and not our fault for a lousy stupid device that will fail here!! thank you!!.

This is the 2nd time this occurs in 3 years . This occurred after it was raining the sensor is in a bad spa or and gm is not taking fault because it is over in miles and yea for the special coverage . I wish that I could just not have the blind spot detection. Causes more problems then what it's worth.

My car was repaired under special coverage n172097060, side blind side alert module, in April 2019. Two years later the same problem has recurred yet now I'm told the special coverage has expired, as the in service date of my vehicle is 2 months past the 6 year limit. The replacement part was also substandard, perhaps even the original design, as it did not last much more than two years. The fact that it failed just two months after the coverage limit is a slap in the face to me as a consumer. The dealer charged me over 900 dollars to replace the side detection system, required to pass NY state inspection.

Have had car at dealership 3 times total for the side detection system message/blind spot indicator lights. First two times the issue was fixed because I have the mpp coverage plan. This time mpp would have covered it but mechanic shows water intrusion. Their was a recall at one time for vehicles up to 80,000 miles. Mine has 124,000 so not covered but when I took it in for the same thing prior did not have 80,000 miles. So either pay the $900 or pay the diagnostic charge of $155 and walk away with issue not fixed . So many complaints on this and gm has done nothing. If I have fixed the module is over $200 for the one side. It keeps going out. Gm should fix this and create another recall for this all so common issue!!.

Side detection system has failed. This detection system is vital to the safety of the vehicle. This is because there are blind spots inherent in the cars design that the side detection system corrects. My Impala ltz is 6 1/2 years old with just under 30,000 miles.

The blind sensor indicators are defective. The right side stays on but the the left side worked accordingly. Without warning the indicator on the left also stopped working. Gm is well aware of the issue but will only fix the issue if it happens within a warranty timeframe. The initial issue with mine happened while driving in a winter storm with slushy roads. The sensors that stays illuminated isn't as much as a safety issue as the one that was lighting up as expected then stopped without warning. This item should be a full recall not a fix it if it breaks scenario. Mine stopped working within my warranty timeframe but because I was a secondary purchaser, I had no way of knowing that waiting until my next oil change would cause me to be stuck with $800 in repairs because gm refused to recall a safety issue item they are well aware of.

When I purchased my car in 2020 I noticed that my blind spot warning light in the passengers mirror was turning on and off. I informed the dealer that I purchased the vehicle from and they said that they would repair it. They had mentioned that there was a defect in the blind spot monitoring system and that they would replace it before I bought it. Within 6 months the light would turn on and off again when there was no other vehicles in my blind spot. For the last year I have been trying to research this problem to resolve the issue. The only thing I have been able to find is that the sensors in the rear bumper for blind spot detection were produced with a faulty seal to keep moisture out of these sensors. If they know that these sensors will collect moisture and cause them to short out then why is there no recall on these sensors? I have had many times that I was driving and went to change lanes when the blind spot monitor would blink to inform me that there is another vehicle there. It has caused me to start to change lanes then have to pull back to avoid something that is not even there. I would think that this is a serious safety issue and might even cause accidents, if it hasn't already happened to other owners? I would like to know what I can do for this issue and to know if I'm the only driver with this problem? this is a problem that has gotten worse over time and gotten to where it happens every time I drive my vehicle.

I had the driver side blind spot detection go bad on my Impala, so it's starting out that my driver side mirror blind side image was blinking, then it stop and was working ok for about three weeks and then a message appears on my dash to fix the blind spot detection system, which if fine, but when I go to the internet to see if I can just do away with this system, the feedback that I've find out was very upsetting, everything on dash doesn't work, can't get into the car, cars don't start. That's fine but when I took the car to get fix the service manager and worker tell me anything can happen when this system goes down. What happens if I'm driving the car at highway speeds and it just stop running, I have no breaks or steering. It's causes an accident. To me this is a very safety issue. And now the passenger side blind side is blinking now, it stop blinking and working fine for awhile and than just quite working.

The issue started out as a warning from the side detection system. In the past week, the issue escalated to all the warning lights on the dash coming on, and then all electronics going dead/dark. The turn signal indicators have no lights and no sound, the radio system is dead, the speedometer and gas gauge are dead. After sitting a few hours, it seemed that things "reset" to just the side detection warning. Most recently, all the electronics are acting strange. Pushing the button on the door handle to unlock it, does nothing to the door lock, however, the display screen shows "tire learning active". When attempting the start the car by pushing the start button, nothing happens. If I put the fob in the slot inside the armrest, it will eventually start, but again all display functions are dead as is the environmental controls (no blower - no defrost- no good on a cold rainy day). Again the signal indicators are dark and silent. The indicator light for the airbags is now illuminated as well. Gm had a short lived (and seemingly secret) extended warranty for the side detection system have this exact issue when water got into the sensors, but that expired nearly a year ago. As this issue makes the car unsafe to drive, it seems that it should be a full recall to address this safety concern.

When the car is turned on and not in motion the dash displays a service side detection system message and the blind spot detectors in the side mirrors do not light up like they should when the car is first started. When driving, at any speed and on any roads or highway, the blind spot detectors do not light. When assessed by a chevy mechanic the side detection sensors were swollen and . Corroded. This sensor is in an area where it is unprotected from the snow and salt. It will cost almost $2,000 to replace two sensors. If not replaced I'm afraid that my vehicles will start catching fire or having other electrical problems like other 2015 Impala owners had happen to them in the past due to these corroded sensors.

Electrical module (side detection) has failed twice. Have to drive to get repair with no gauges, signals, or heat. This could easily be a safety issue. The car was parked, upon starting, got several error messages including side detection issue, air bag failure, tire inflation failure. No speedometer, tachometer, heat - but the steering wheel and seat electrical heat still work!.

Issues with blind spot system, sometimes causes all power on dash to shut off while driving, have read many many other people with the same issues online. Sounds like the blind spot monitor modules are trash, but not recalled. . . .

Side detection system light on dash say service but the side detection light onbthe mirror stays on even when the car is off.
