2015 Chevrolet Impala Driver assistance Problems

I am leasing the car out. I’ve been leasing it out for the last three months since March I went delinquent on one of my payments because I have my mechanic look at it and type my VIN number in and they told me that I was recall he couldn’t tell me why I was recall Two days ago, which was Saturday, June 28. The lender called me and told me that the car was recalled. I tried to call him back to discuss what can be done. I have the payment, no response and I don’t have my car and my belongings are in it.

Side Blind Zone Alert (SZBA) system continues to be an issue with this vehicle. Sensing module(s) on inner left or right side of bumper cover fail due to water intrusion. When sensing module fails, "Service Side Detection System" message will appear on driver information center on instrument cluster. General Motors has previously issued a special coverage "N172097060", which is available on NHTSA website. As indicated in the special coverage document, if the issue is ignored, "the condition could result in the corruption of LS GMLAN that may result in the loss of some driver interface functions such as cluster, infotainment, displays, chime, and passenger presence detection (passenger airbag could be suppressed). Within approximately 30 days of the "Service Side Detection System" message, while driving, instrument cluster speedometer and tachometer went dead, and airbag warning system notification, anti-theft system, tire pressure monitoring system all illuminated. In addition to no speedometer reading, vehicle ignition/security interlock was causing vehicle to run rough. Vehicle would not immediately restart after shutting vehicle off. This is the 4th time a SBZA sensing module has failed on this vehicle. First failure was replaced under factory warranty, second failure was replaced under special coverage N172097060, third failure was replaced out-of-pocket. Contacted General Motors/Chevrolet, and they are not interested in providing continued coverage of the issue, which is a known issue, and likely a design defect, as the design was changed for later model years.

GM has a know issue with the side detection system and refuses to do anything about it even after there service bulletin expired. When this fail it can cause other issues with the dashboard system failure and more. In this case the system would never shutdown draining the battery.

The blind spot warning system stopped working, and yes it is available for inspection upon request. I have heard this leads to further electrical problems and am worried this may compromise my safety if not dealt with. The problem has not been confirmed by a dealer. The component has not been inspected. There was a warning that popped up stating “service side detection system” that appeared randomly on my drive home the other day. I had not hit anything or done anything to the car that might have caused this.

The Side Detection System failed. Both rare modules are shorted. The defective module drain out the battery, causing engine start failure. And the defective module may cause fire. I have one side of the modules repaired in three years ago. Now both sides are failed. I had two jump start in the recent month. Every time I start the engine, warning for service of Side Detection System shows up.

In April 2019, the side detection module was replaced under warranty, at 21,500 miles. The same ‘issues’ are reappearing, where a warning is illuminated on the side mirror when no cars are present. If the dealer/ mfr replaced the original modules and wiring harness with the same items, this would only delay a reoccurrence. I called Chevy Cust. Sec for assistance, and they said their ‘recall’ program expired in 2019. The car currently has just 47,000 miles and the the modules should not have failed a second time. There is obviously a design flaw, allowing water penetration, and Chevy did nothing to prevent it.

Have had issues 2 times since owning this vehicle, both times sensor was replaced by dealership. Was told by service at dealership that this is a known issue for GM. Dealership found side detection modules swelled and connections corroded. Again for the 3rd time since owning this car from new. They, the dealership, cost the replacement of the module at $980.00 including labor. To fix an issue they have known about for years

I have had the blind spot modules replaced two times already and they are out for the third time. I have had to replace them like just over every 2 years. This time I had loan my car to my daughter, due to any accident she had with a deer, and had her four kids in the car when multiple modules started shutting down and nearly leaving her stranded. When I was able to inspect the car i found the the blind spot modules where extremally corroded and showed signs of melting to almost catching fire. I believe that these are a safety issue, and need to be recalled and problem fixed with a reliably solution. I am a ASE Certified Master Technician and have been for well over 38 years. and have seen many of these GM modules go bad multicable times.

My side detection system has failed and not working on my 2015 ltz. Blind spot light stays on even when car is off. It’s causing other lights going crazy on and off. No check engine light on just the side blind spot indicator lights stay on. My car only has 70k miles it’s been happening for 1 wk I’m afraid to drive it after reading online that a clients impala nearly caught on fire. I’m reading that there is a recall with 2015 impala # n172097060 side blind zone alert module water intrusion. Please advise if there is anything Chevy/GM can do for me. I’m afraid to drive car and feel it’s a hazard driving around with faulty blind spots light.

Taillight gasket failed and leaks water resulting in water leaking into trunk anytime it rains or go through car wash. This caused corrosion to the amplifier shorting it out, there is now no sound or on star available. It also caused the blind spot detection monitor to have issues and no longer work. Upon inspection when the vehicle is running the wires sometimes start smoking white. Dealer said there was no issue, obviously the radio doesn’t work, the screen doesn’t even light up, no backup camera, no sound warning if the forward collision system is engaged, no seatbelt ding, no blinker sounds, no rear detection system or cross traffic warning system.

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!!

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.

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.
