The vehicle with only 29,775 miles on it, and I bought it new, made a knocking noise in the brakes and the brake pedal jumped up and down at first stop sign when I left my house. I reapplied the brake to see if it would work. It did. I turned onto the highway and within two blocks the vehicle shifted itself into N, a message on dashboard said pull over, contact service immediately. I was able to coast then turn onto a side street. Upon stopping the vehicle, another warning came on the dashboard: Reversing Not Possible Service Required. This vehicle has had quirky electrical problems from the beginning. I have reported to the dealership at least 3-4 times. I believe this could have been a very dangerous situation for me and my family if I was on an Interstate. I have no confidence in this vehicle now.
