Upon opening the sunroof while driving, the sunshade track bunched up and got stuck while opening. I was able to unbunch the track the get the sunshade to close, however, the fabric ripped away from the track on both sides. When the sunroof is opened, the fabric falls down into the car and completely blocks the view out of the back window. I tired putting the fabric up in the space it should roll into, but it will not stay and falls down while driving. I stopped using the sunroof for this reason. Now the fabric hangs down into the car. This happened almost a year ago. The fabric has continued to hang down further and further into the car. It is beginning to fall into the line of vision of the rear window. I used safety pins to hold it up, but it continues to hang down further. I have decided to get it fixed for this reason. It will cost almost $800 to have it repaired. This is clearly a safety hazard. I have read several forums on other owners with the same safety issue. A service repair bulletin has been issued for this problem, but it should be a safety recall.

Side Blind Zone Alert Module, Service Side Detection System

NHTSA ODI 11516403

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

My son (a brand new driver) was driving to school with me in the passenger seat on surface streets at approximately 45 mph at 0600 and an error message came on the console about “Service Power Steering - Drive With Care” or something akin to that and my son was unable to steer the car. He was able to slightly steer it into a turn lane (right hand turn into a neighborhood) and almost struck an oncoming car. He was able to stop and switch seats with me. Thankfully traffic was light enough and no one was behind us for me to back up about 10 feet to enable me to muscle the car into the neighborhood side street to pull over. I immediately turned the car off, waited ~30 seconds and restarted the engine…still couldn’t drive and error message came up again. Waited another 5-10 minutes and turned the ignition and was able to turn the wheel with ease, so I drove the car the ~5 miles home with no issue, but immediately called a service repair shop; they told me that this was a known issue. (WHAT THE WHAT?!?! Losing the ability to steer while careening down the road is a FLIPPING KNOWN ISSUE AND THERE HAS NOT BEEN A SAFETY RECALL?!? WE COULD HAVE BEEN KILLED AND KILLED OTHERS!). I immediately took it to the repair shop as I refused to drive it as it was unnecessarily unsafe! The repair was quoted as $5,200 (brand new GM part replacement) or $3,800 (reconditioned part - which ironically had a better warranty on it than the genuine GM part!)…I needed my car so I authorized the repair. Not happy! (A side note and a huge slap in the face is that my father did and my husband actually still works for GM…I’ve seen all the near-misses reported here and NO ONE KNEW THIS WAS AN ISSUE UNTIL DRIVING AND THE ABILITY TO STEER WAS LOST! Thank goodness we were on a surface street and not interstate! My novice driver could have EASILY been killed if he was in a different driving situation. GM NEEDS TO ORDER A RECALL!!

Both taillights are leaking through a gasket in the taillights causing pooling of water in the majority of the trunk and through two layers of carpet. This is causing mold to grow in trunk.

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.

Side detection system is failed. Used for blind spots and I know this can cause more issues with car.

In September 2021, my vehicle had approximately 130,000 miles and began to experience intermittent power steering failures. During these times, which were always unexpected, the Stabilitrak light would illuminate on the dashboard, and a "Power Steering" advisory would appear on the dashboard display screen. Power steering would then be unavailable until the vehicle was restarted. I am experienced in vehicle repair, and I isolated the left rear wheel speed sensor as the cause of this fault. I changed the left rear wheel bearing with an OEM replacement, and the problem went away. In January 2023, at approximately 160,000 miles I began noticing that my right rear wheel bearing was worn, and I changed it with an OEM replacement. Roughly 2 weeks later, my power steering has randomly begun to disengage while driving. The only message I receive is a "Power Steering" advisory, but this time, Stabilitrak remains operational. I am very concerned about this vehicle's design, which apparently kicks power steering offline as a result of anomalies with the wheel bearing speed sensors. The speed sensors consist of a circular magnet attached to the back of the bearing, and a device mounted within the bearing bracket which tracks the frequency of that magnet's rotation. The circular magnet is subject to corrosion and fracturing, as I discovered in September 2021, and again in January 2023, while replacing each bearing. This vehicle is quite heavy. A significant amount of damage, injury, and death is likely to occur if a driver with less capabilities than me is met with this awful fault while driving. Steering the vehicle in this condition, while below 50 MPH, is nearly impossible without enormous effort, especially around common 4-way intersections and at slow speeds. I believe speed sensor anomalies should not trigger a complete loss of power steering.

The contact owns a 2015 Chevrolet Impala. The contact stated while driving 40 MPH with the cruise control activated, the cruise control feature inadvertently deactivated, and the vehicle decelerated. An unknown warning light was then illuminated. The contact was able to accelerate, and the vehicle started operating normally. The vehicle was diagnosed by the dealer, and the contact was informed that the side detect module (B1010-00) needed to be replaced. The vehicle was not repaired, but an appointment was scheduled. The manufacturer was contacted and stated that the vehicle was out of warranty and referred the contact to the NHTSA hotline for assistance. The failure mileage was 30,000.

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.

I was driving on the highway at about 60 miles per hour and my power steering went out without warning. The car was stiff and difficult to move and put the life of myself and my child in danger as well as others on the highway at the time. I took the car to a shop and they confirmed that the steering rack had failed or was near failure. It wasn't until I was able to navigate off the highway after driving to a Jiffy lube that the light ultimately came on.

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!!
