2015 Chevrolet Impala

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.

The contact owns a 2015 Chevrolet Impala. The contact stated that the check engine warning light was illuminated. The vehicle was taken to an independent mechanic where a code reader determined that there was a defect with the dual battery control module. The mechanic recommended that the module and both batteries be replaced. The dealer nor the manufacturer was notified of the failure. The vehicle had been repaired. The failure mileage was approximately 140,000.

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.

The manufacturer was contacted and notified of the failure and referred the contact to the NHTSA to file a complaint. The approximate failure mileage was 100,000.
