* Shift Interlock Mechanism: This is the most frequent culprit. The mechanism prevents shifting out of park unless the brake pedal is depressed and/or the ignition is on. Problems can arise from:
* Faulty Brake Pedal Switch: The switch might be malfunctioning, failing to signal the car that the brake is pressed.
* Low Brake Fluid: A low brake fluid level can trigger a safety feature that prevents shifting.
* Faulty Shift Cable/Linkage: The cable or linkage that connects the shifter to the transmission might be damaged or out of adjustment.
* Electrical Issue within the Shift Interlock System: A short circuit, faulty wiring, or a problem with the shift interlock solenoid can prevent the release.
* Transmission Problems: While less common as a primary cause of being stuck in park, transmission issues *can* contribute:
* Low Transmission Fluid: Similar to brake fluid, low transmission fluid can cause malfunctions.
* Internal Transmission Problems: More serious issues within the transmission itself could interfere with shifting. This is usually accompanied by other symptoms like rough shifting, slipping, or noises.
* Parking Pawl: This mechanical device physically locks the transmission in park. A problem with the pawl itself (rare) or its linkage could prevent release.
* Steering Column Lock: Although less likely to directly prevent shifting out of park, a malfunctioning steering column lock could sometimes interfere with the shifting mechanism.
* Faulty Shift Lever: A damaged or broken shift lever could prevent it from moving properly.
Troubleshooting Steps (Do these in order, and always prioritize safety):
1. Check Brake Pedal and Fluid: Make sure the brake pedal is fully depressed and that the brake fluid level is adequate.
2. Ignition: Ensure the ignition is turned to the "ON" position (not just accessory).
3. Try Again Gently: Try shifting the lever again gently. Don't force it!
4. Check for Obstructions: Make sure nothing is interfering with the shifter.
5. Check Transmission Fluid Level: Check the transmission fluid level and condition.
6. Battery Voltage: A low battery can sometimes affect electronic systems, including the shift interlock.
If none of the above steps work, you should:
* Consult your owner's manual: It may have specific troubleshooting advice for your model year.
* Call a roadside assistance service: They can diagnose the problem or tow your vehicle to a repair shop.
* Take it to a qualified mechanic: A professional can diagnose the problem and perform the necessary repairs.
Important Note: Forcing the shifter can cause further damage. Avoid doing so.
