What Causes the Steering Wheel and Accelerator to Become Heavier?
2 Answers
If the steering wheel suddenly becomes heavier and you notice significant resistance when turning, or if the steering wheel does not automatically return after a turn, it may be due to a flat tire on one of the front wheels. For hydraulic power steering, the issue could be with the power steering fluid. For electric power steering, a blown fuse or a short circuit in the wiring may be the cause. Common reasons for a heavy steering wheel in cars: Low Power Steering Fluid: For hydraulic power steering, check if the power steering fluid is low or if there is a leak. If the fluid is low, refill it to the normal level. If the fluid level is normal, check if the power steering pump belt is too loose. Tighten the belt if necessary. Also, check if the fluid is too dirty, which can reduce its flow efficiency. Generally, the fluid should be replaced every 2 years or 60,000 kilometers. Blown Fuse: For electric power steering, check if the fuse is blown and if there are any open circuits or short circuits to ground in the wiring. Tire Pressure Loss: Check the tire pressure. A flat tire can also make the steering feel heavier, and you may need to inflate the tire.
It's really frustrating when the steering wheel or accelerator suddenly becomes heavier while driving. A heavier steering wheel is mostly due to issues with the power steering system—perhaps the power steering pump is faulty or the steering fluid is insufficient, making turning the wheel particularly strenuous. Sometimes, a loose belt or complete fluid leakage can also cause this. On the other hand, a heavier accelerator is usually caused by a dirty throttle body or a malfunctioning accelerator position sensor, making the pedal less responsive than before. I’ve encountered this situation myself—initially, I thought it was due to low tire pressure, but after inspection, I found the power steering fluid was nearly empty. It’s crucial to visit a repair shop promptly to refill the fluid or replace faulty parts; otherwise, it could compromise driving safety, especially when losing control during high-speed turns. Always stay vigilant and address abnormalities without delay. Regular maintenance, such as annual checks on the power steering system and engine components, can prevent these issues. Simple DIY tasks like cleaning the throttle body can also be helpful. In short, when driving comfort is compromised, act promptly—don’t wait for major problems to arise.
