2015 Chevrolet Impala

The electronic power steering intermittently fails while driving, especially during or after wet conditions. Without warning, the steering wheel becomes extremely stiff and difficult to turn, and a “Service Power Steering” message appears. The failure occurs at any speed and lasts about 1–3 minutes before returning to normal. This has happened multiple times under similar conditions. This creates a serious safety risk because it occurs at highway or city speeds without warning, making the vehicle difficult to control and increasing the risk of a crash. No prior warning is given before the failure other than the dashboard message at the time of the incident. Cause is UNKNOWN. There are numerous reports from other drivers describing similar symptoms, suggesting a potential widespread defect in the electronic power steering system or related components.

The stabilitrak notification appeared on my dashboard while driving on the highway, which immediately caused the car to slow down. It was a hazard as I had to maneuver over 4 lanes on a highway at high speed to move to safety. This issue has occurred three times and is currently on the fourth as the vehicle is at the Chevrolet dealer. It is going on three weeks on my fourth return in 6 months with no current feedback. I have taken the vehicle to the dealer each time for this exact issue which has occurred every 6 months after the initial repair, my vehicle was there for approximately three months as they stated I needed to replace the transmission. Six months from that date the issue occurred again and it was replaced as it was under warrant. The third time I had to pay for the repair as the dealer stated some sensors needed to be replaced. Now six months later again, it is at the dealer and I am waiting for the response. Each time this issue occurred, I was traveling at high speeds which almost resulted in accidents that I somehow managed to avoid. There were no other warning signs that this issue was going to occur. It just happens spontaneously. I have seen several complaints about this issue with Chevrolet made by mother customers going back as far as 2012 to no resolution but thousands of dollars spent with no real solution/answers.

Service blind spot detection system alert come on i took it to the dealership and paid 95.00 to diagnosis they wanted 1900.00 to fix the problem 2 weeks later while waiting for an appointment the entire system is failing Forward collision warning, Lane departure warning ,and Parking collision warning. the dealer now wants another 95.00 to re-diagnosis seeing as only the blind spot was the only warning at first. I'm being told this could lead to the vehicle shutting down even while driving
