The most common cause of a brake pedal being locked and a car not starting is that the parking brake has been left engaged. This means that the brake pads are still pressing against the rotors, preventing them from spinning when you try to start your car. Additionally, if your vehicle has an automatic transmission, it may be stuck in park due to a faulty shift interlock solenoid or switch which prevents the shifter from moving out of park unless the brakes are applied.
Another possible cause is air in the braking system, which can prevent proper pressure from reaching the brakes and locking them into place while also preventing you from starting your engine until this issue is resolved.
Knowing why is my Brake Pedal Locked and car won’t start is crucial to stay safe during the drive. In this blog post, we will explore the reasons why the brake pedal is locked and the car not starting.
Why is My Brake Pedal Locked And Car Won’t Start: Find the Reasons
If your brake pedal is locked and your car won’t start, there could be several potential reasons for this issue. Here are some common explanations to consider:
1. Shift Interlock System: Many modern vehicles have a shift interlock system that requires the brake pedal to be depressed before the vehicle can be shifted out of “Park” and started. If there’s an issue with this system, such as a malfunctioning shift interlock solenoid or a faulty brake switch, the brake pedal might become locked, preventing the car from starting.
2. Dead Battery: A dead or weak battery can cause various electrical systems in the car to malfunction, including the interlock system that requires the brake pedal to be pressed before starting. If the battery voltage is too low, it might not provide enough power to release the brake interlock.
3. Faulty Brake Switch: The brake switch is responsible for sending a signal to the vehicle’s computer when the brake pedal is depressed. If the brake switch is malfunctioning, the computer might not receive the signal, preventing the car from starting.
4. Ignition Switch Issue: A faulty ignition switch can prevent the car from recognizing that the brake pedal is depressed, thus locking the brake pedal and not allowing the car to start.
5. Transmission Issue: Problems with the transmission linkage or the transmission itself can sometimes prevent the vehicle from recognizing that it’s in the “Park” position, which in turn might prevent the car from starting.
6. Anti-Theft System: Some vehicles have security systems that can lock out the ignition if they detect a potential theft or unauthorized access. If there’s an issue with the anti-theft system, it might prevent the car from starting.
7. Hydraulic Brake System Issue: In some cases, a problem with the hydraulic brake system, such as a brake fluid leak or air in the brake lines, can affect the functionality of the brake pedal and the vehicle’s starting process.
8. Faulty Starter: While the brake pedal being locked might not be directly related to a faulty starter, a malfunctioning starter can prevent the engine from cranking and starting.
9. Electronic Control Module (ECM) Issue: The ECM, which controls various functions of the vehicle, including starting and shifting, could have a malfunction that’s preventing the car from starting.
10. Mechanical Issue: There could be a mechanical issue within the brake pedal assembly or the linkage that’s preventing proper engagement of the brake pedal and its associated systems.
Given the complexity of modern vehicles and the potential safety implications, it’s advisable to have a professional mechanic diagnose and repair the issue. They have the expertise and equipment needed to accurately identify the root cause of the problem and perform the necessary repairs to get your car running again.
