The tail lights and brake lights were not working. Discovered during annual state required inspection in September 2015. I was driving the vehicle regularly on rural, city and highway roads without tail and brake lights and was unaware. A repair to the electrical wiring was required. Addtionally, the trunk latch was only working intermittently prior to this repair. Since the wiring repair was made, I have had no issues with the trunk release not working. The rear passenger door on the drivers side doesn't lock and unlock when you depress the keyfob or the button in the car to lock all the doors. This is a very infrequently used door and it is the door used the least in the vehicle. Dealer states it is a bad door latch. I have not repaired it. It doesn't always open from the outside, sometimes I have to reach in and open it from the inside to get the door open. On 01. 12. 2016 the car radio stopped working. The fuses are good and intact. The bluetooth no longer works since the radio doesn't work. It is completely out of service, nothing works on the radio. I relied heavily on the bluetooth for hands free phone calls since the vehicle is manual transmission. Vehicle was stationary when discovered. Vehicle has approximately 55,000 miles on it.
