My steering locked up as I was driving. I was making a left hand turn and it would barely turn. As I straightened the steering wheel it was still extremely difficult to turn. I managed to get it pulled in to the gas station and turned off the motor to pump my gas. It did fine after I cranked it back up.
On 7/17/19 my car lost power while driving on city street. Unable to steer or control vehicle. Took to dealer who said there were no error codes shown and that it was the electric oil pump. On 8/12/19, the same thing happened while driving on expressway. Complete power failure while vehicle was in motion. Unable to steer or control car. Took back to dealer. Again, no error codes found. They later claimed that a relay had melted and that was the problem. On 12/28/19, again driving 70mph on busy expressway, vehicle lost all power and I was unable to steer car. Took to dealer on 12/29 after it happened a second time in two days. There were unable to look at vehicle that day and told me to bring back next day. It stalled again while I was leaving parking lot, I asked the maintenance tech to come and look to see what was happening, he refused. Dropped car off on 12/30. On 1/2/20, dealer called to say no error codes found, after driving 100 plus miles, were unable to determine cause of problem and I should pick up my vehicle. I explained this is unacceptable. They called me back later claiming it is the electric steering column portion of motor control power steering rack and want $1800 to fix. This is a major safety issue, loosing complete power and ability to steer while driving. Dealer has done nothing to reassure me that this is the actual problem.
