The most common cause of a stuck accelerator is usually a floor mat that has become wedged under the pedal. Floor mats, particularly those that are not securely fastened or are too large for the vehicle, can slide up and interfere with the accelerator pedal, preventing it from returning to its normal position.
Another common cause can be dirt or debris that has accumulated around the pedal mechanism, causing it to become sticky or blocked. Additionally, mechanical issues such as a malfunctioning throttle cable or a stuck throttle body can lead to an accelerator sticking. It’s crucial to address this issue immediately, as it can cause serious safety risks.
