2015 CHEVROLET IMPALA Complaints

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.

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.

While driving this vehicle, the Traction Control will turn off along with the Stabiltrack function. The transmission will drop into "limp" mode and function on a "basic" level. This causes the vehicle to loose power and become very sluggish to control or operate. A code for "loss of TCM communication" to be found in the computer via the ADL. To remove the code and restore communication to the Transmission Control Module, I have to remove and reinsert the wire coupling connection wire harness at the TCM. The TCM will now communicate with the ECM. This is a recurring problem solved by this action.

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.

Front Right lower control arm w/o police right front wheel. Tpms system. This will be the second time I’ve had to replace the front lower control arm the tea PMS system does not work ABS traction control are off totally the same year of car make model everything was recalled to have this fixed but it was only with the police cars what makes you think that the ones that weren’t police cars didn’t have the same issue it cost $427.20 to fix. I also understand that my vehicle you’re making model it’s not the only one having this issue of having to replace it over and over as far as electrical something keeps moving or coming on or off in the car it’s worn down to batteries it happens at any time I can walk by the car and making the noise. I have to keep replacing the tires due to this all I know is that when you’re driving it more getting ready to turn it makes a loud crunching grinding noise it can happen at any time it’s getting harder to control the steering wheel. The cost of replacing the tires is ridiculous 2xs in a year or less. Gas let’s not even go there. Traction and stabilization always on along with brake assist and tpms front two tires stopped working. And once again it’s doing it. Not sure of exact date but before 2020

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 "service stabilitrak" light and engine light has returned making the vehicle non-operational once again. I have spent over $2500 in the past 12 months at an authorized Chervrolet dealership attempting to repair this exclusive, patented General Motors safety system, however, the system continues to malfunction. I cannot be the only owner of a GM vehicle with this frustrating, expensive issue. Please assist with a recall and/or inquiry to GM/Chevrolet. Previous NHTSA tracking number 11444992.
