In Parts 1 & 2 of this series, we discussed various reasons why your tires might be creating lots of noise. Now, in the 3rd and final part, we present the solutions.
Q: “I just got in my car to go to work and could not, for the life of me, get it out of park! I know this sounds simple; You press the brake, and you put it in drive, but it simply isn’t working today. What happened?“ ~ Stuck in Victoria, BC
A: This can be very frustrating, but not unheard of. You see, since the early 1990s, vehicles with automatic transmissions have been equipped with a key-shift interlock safety feature that locks the shifter in the Park position each time the shifter is placed there. In order to move the shifter out of Park, the key must be in the ignition switch and the switch must be in the “ON” or “RUN” position.
In addition to the key-shift interlock safety feature, many vehicles prior to 2010 and all vehicles 2010 and newer are also equipped with a brake-shift interlock safety feature, which, in addition to the ignition switch being in the ON or RUN position, the brake pedal must be depressed and the button on the shifter must be pushed in simultaneously before the shifter can be moved out of Park.
What could be the cause?
The main components that control the locking and unlocking of the shifter are the vehicle ignition switch, the brake light/stoplight switch, and the shift interlock solenoid. When one of these components fails, you may not be able to move the shifter out of Park. Additionally, if your vehicle’s battery is dead, the shifter will be stuck in Park. More often than not, people have been charging their phones or tablets in the vehicle’s 12V “cigarette lighter” ports and have blown a fuse. The fuse that protects that circuit is also connected to the brake light switch so the shift interlock solenoid will no longer function. We can help to replace any blown fuses or troubleshoot which of the connected components is failing to get you out of Park and back on the road in no time.
