If your gas pedal is stuck, it can cause unintended acceleration, making the vehicle unsafe to drive. A stuck accelerator may be due to mechanical binding, a faulty throttle body, or issues with the electronic throttle system. Immediate inspection is critical to prevent accidents and ensure safe operation.

What does it mean if the gas pedal is stuck?

This means the accelerator is not returning to its normal position when released, keeping the engine revving or the car moving forward unexpectedly. The cause can be mechanical (linkages, cables) or electronic (throttle control system).

Common causes of a stuck gas pedal

• Mechanical binding in the accelerator cable (older vehicles)
• Faulty or dirty throttle body sticking open
• Floor mats or debris obstructing the pedal
• Worn or damaged pedal assembly
• Electronic throttle control (ETC) system malfunction
• Vacuum leaks or intake system issues

Why do you need to fix this problem quickly?

A stuck gas pedal can cause sudden, unintended acceleration, which is extremely dangerous. It puts you, passengers, and other road users at risk. Immediate attention is required to avoid accidents.

How do you know when to get it checked?

You should book an inspection immediately if:

• The gas pedal does not return smoothly when released
• The engine continues to rev after lifting your foot
• You feel resistance or sticking when pressing the pedal
• The Check Engine Light comes on with throttle-related codes
• You’ve noticed sudden surges of acceleration

What happens during an assessment?

A mechanic will:

1. Inspect the gas pedal, linkage, or electronic sensor
2. Check for obstruction by floor mats or debris
3. Inspect the throttle body for dirt, carbon buildup, or sticking
4. Test the electronic throttle control system for faults
5. Clean, repair, or replace faulty components as required
6. Road test the vehicle to confirm the issue is resolved

How much does it cost to fix?

Costs vary depending on the cause. A simple obstruction or throttle body cleaning may cost $120–$250. Replacement of electronic throttle components or pedal assemblies can range from $400–$1,200+.

Is it unsafe to drive with a stuck gas pedal?

Yes. Driving with a stuck gas pedal is extremely dangerous and should not be attempted until the problem is fixed. The vehicle should be towed to a workshop for immediate inspection.
