Purchased new 2019 Malibu RS end of May. Had immediate intermittent violent steering wheel shake between 35 - 45 mph. Detailed several incidents - there were many more - and returned to purchasing dealer - service couldn't duplicate the problem. Returned the car again at ~ 6300 miles with 16 incidents detailed - and told service that I felt the car was unsafe to drive and I requested a buyout with Chevy Customer Satisfaction. Filed a request with GM Executive Referral and was told that because I filed a report for a request for a buyout - NOT safety - that my case would be "escalated" and the advisor would be contacting Regional Chevy Service and After Sale Rep regarding the problem with the car and he would get back with me. Dealer provided a vehicle. After multiple communications with GM Exec Referral and dealership personnel, last Tuesday, I was advised that the car had been fixed per a recent service repair bulletin and that the car had been driven about 30 miles and the problem couldn't be duplicated. Spoke with GM Exec Referral who then told me that he had contacted the dealer and was told that the car was repaired and ready to be picked up and any more about a buyout would have to go through the dealership management and not Chevrolet. I had requested to speak with GM Regional Service and After Sales Rep but was told that was not possible. Also requested a written report on what GM Exec Referral and Chevrolet customer Service did with my request and was told that they will not put anything in writing in relation to my case. I requested that my case be kept open and that I would discuss the buyout next week with the dealership General Manager regarding a buyout. Chevy put out a bulletin August 19, 2019 regarding the steering wheel shaking and shimmy and it sounded as if it was written by an engineering intern. It was advised that engineering was working on a solution and that the bulletin affected all Malibu's from 2016 - 2020. The ultimate "fix" was a service repair bulletin to reprogram the ECM issued a week or so ago. In the previous service trips, none of the incidents read out on the computer. There were at least three incidents of the steering wheel shaking between 65 - 70 mph. Has anyone had this problem and is anyone aware of the "fix" being just a re-programming or also a mechanical replacement of a part / parts? And which? Did the "fix" work? My dealer has been excellent in assisting me. Chevy Customer Service / GM Exec Referral...…… not pleased. Any insight / knowledge of this existing problem and the "fix" ? Thanks!
