Open the full vehicle complaint log (all categories)To whom it may concern; I am writing you with deep disappointment as I am experiencing dissatisfaction with the quality of car that I leased on December, 06, 2021. Panamera was always my dream car, however, today it is a life threat to me and my family. The car is experiencing failure during drive, it self shifts itself to neutral while driving as well failed AC system. Yesterday, 3/19/23, on freeway, I almost got into car accident because of that shift. The car suddenly stopped, and almost got hit by other 3 cars behind me. The problem started since December 2022 with a frequency of once or twice a month. I made an appointment with Rusnak Pasadena dealership shop to run diagnostics. They found nothing… based on 15-20 min drive. The problem started increasing in frequency to 2-3 times a week. It is extremely unsafe now. During time I was leasing car, I never missed any payments, was compliant with due dates, being a proper customer to Porsche dealer (which counts back for many years now). Again, I love the car, it is my dream car, however it is a threat now to my life and my family life. I beg your attention to this matter, as it is frustrating and disappointing experience now. Thank you for your time and business, I would like to remain good customer of Porsche in future, [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
