[AubreyLee]

Reasons for feeling the steering wheel is heavy: 1. Insufficient or leaking power steering fluid; 2. Holding the steering wheel at full lock for more than 5 seconds; 3. Low tire pressure; 4. Poor electrical contact inside the power assist system; 5. Contaminated power steering fluid with unclean mixed gases or impurities. Effects of a heavy steering wheel: 1. Reduced maneuverability; 2. Potential safety hazards during driving. Solutions for a heavy steering wheel: 1. If the car's hydraulic power steering is low on fluid, top it up to the normal range; 2. For issues with the electronic power steering system, check and replace fuses, and inspect the wiring; 3. Check tire pressure and inflate if it is too low.
