2015 Chevrolet Impala Limited steering problems

“Complete loss of power assist steering resulting in difficulty in steering the vehicle at any speed. DIC messages indicate: loss of power steering, drive with caution, service traction control, and service ABS. ABS and traction control warning lights remain on and illuminated while driving. These indicators occur each time the vehicle is restarted. This problem originally started about two and a half months ago, and the power steering loss, for a while, was intermittent until recently. The vehicle has not been inspected been inspected by mechanics to date. I have researched hundreds of Impalas online with the same problem with a majority of them remaining unresolved and no manufacturer recall being issued. The vehicle mileage is currently 31, 104 miles and is not driven often because of the problem and the fact that I own two other vehicles.”

“About two years ago I parked in front of a business in Sun City West Arizona. When i came out to leave, my steering wheel would hardly turn. I went home and when I came back with a neighbor, the steering wheel was working as it should. About three weeks ago, I was turning onto a major street in Sun City West, Arizona. I got a notice on the info screen that the power steering was disabled. I had to force the steering just to get around the corner. I drove to a nearby parking lot. The steering took a tremendous amount of effort to turn the steering wheel. I almost hit a semi truck trying to go around a corner. It was very dangerous. After parking and leaving it for a short while, steering returned to normal. On a major highway a serious accident could have happened. I read online that in 2015 General Motors recalled roughly 1.2 million model year 2015 trucks and SUVs globally for a problem with the electric power steering system. GM previously recalled nearly 700,000 model year 2014 pickups for the same problem. My car with the electric power steering problem is a 2015 Chevrolet Impala. I am afraid to drive the car now. It could happen anytime again and cause a wreck.”

“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…”

“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…”

Safety GM”

“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.”
