2015 Chevrolet Impala

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.

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.

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.

The stabilitrak system GM installed on my vehicle repeatedly indicates a "service" notification. Once this occurs, my vehicle loses power and the ability to shift into any driving mode. This issue began around 60,000, I currently have 77,500+ on my vehicle. GM issued a technical service bulletin (PIC5992A) for my vehicle, however, denies it's the issue and will only attempt a repair from a computer code, which they continue to fail to replicate. The occurrence of this issue is especially worrisome on any interstate highway. ODI 11406439

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.
