Why can't the accelerator pedal be lifted?
2 Answers
The accelerator pedal cannot be lifted mainly due to the following reasons: 1. The automatic transmission hydraulic oil level is too low; or the automatic transmission hydraulic oil level is too high, generating a large amount of bubbles when violently stirred by the planetary gear set during operation. 2. The friction plates or brake bands of the automatic transmission's clutch or brake are excessively worn or burnt; the automatic transmission oil pump is excessively worn or there is a main oil circuit leak, resulting in excessively low oil pressure. 3. The one-way overrunning clutch of the automatic transmission is slipping; the sealing ring of the automatic transmission's clutch or brake piston is damaged, causing oil leakage. 4. The sealing ring of the shock absorber piston is damaged, causing oil leakage.
I just started driving when I noticed the accelerator pedal was stuck and wouldn’t spring back—it took a lot of effort to move it, which was really dangerous. Usually, this happens due to a worn or damaged spring in the throttle system, rust or jamming in the metal components reducing elasticity, or dust buildup in the pedal’s pivot point that can cause sticking over time if not cleaned. I’ve also experienced thick floor mats blocking pedal movement, so check for any obstructions around the pedal. Regular maintenance is key—clean dust monthly or apply lubricant as prevention. If the issue persists, visit a mechanic to check if the spring needs replacement or for a full inspection—never force it yourself. Safety comes first: if the pedal sticks, pull over immediately and avoid highways to prevent accidents. Also, don’t overlook these small details during routine car care—they can save you from bigger headaches.
