Have experienced ongoing electrical system mirror problems, with my 2008 Porsche Cayenne, where the outside mirrors moved on their own while driving and parking. First experienced this electrical system mirror problem on (3/23/09) at 12,391 miles, as this car was taken to same dealership where I had purchased it (inskip penske Porsche in warwick, ri (12) separate times for unsuccessful attempts at repair. The repair invoices are available for the following visits: 3-23-09 = 12,391 / 3-31-09 = 12,592 / 4-2-09 = 12,992 / 9-13-10 = 25,668 / 9-28-2010 = 26,186 / 12-16-10 = 28,179 / 8-24-11 = 38,186 / 9-13-11 = 38,664 / 9-30-11 = 39,249 / 12-19-12 = 47,715 / 1-24-13 = 47,973 / 3-7-13 = 48,199. Purchased the car brand new on (2/4/08) with only 24 miles on the odometer. Computer control unit was replaced at least 10 separate times, as this car may have had software virus & or an electrical shortage. The dealership seems not to not know how to properly program this car, as they claimed that the car was ready to be picked up on (3/7/13) after being in their shop for 37 days since the 11th visit beginning on (1/24/13). Less than 12 miles later, I had to return the car back to the dealer for the 12th time on (3/7/13), because the spare key which they had programmed we suspect may have had old software which corrupted the computer system. This problem again caused the mirrors to move in all kind of different directions, thus causing a major safety issue when driving or operating the vehicle. They finally ordered another computer replacement & 2 new keys which they programmed successfully without further problems. Prior to this 12th repair, I came close to being involved in at least 4 near mis accidents, as cars were not visible in my blind spot, especially when the mirrors move on their own. Have gone through two arbitrations. Updated 03/15/13
