What Are the Reasons for a Sudden Increase in Resistance While Driving?
2 Answers
There are several reasons why a car may suddenly feel increased resistance: brake issues, motor bearing damage, or motor water ingress. Below are the details: 1. Brake Issues: First, use the kickstand to lift the vehicle and manually rotate the wheel and brake lever. Check if the rotation is smooth and if there is any locking issue. 2. Motor Bearing Damage: Inspect the motor bearings by shaking the motor left and right to see if there is any play in the bearings. 3. Motor Water Ingress: Poor motor sealing can lead to water ingress. Water inside the motor causes rust, and a large amount of rust debris can impede motor operation. Users can open the motor and use sandpaper to remove the rust.
As a veteran driver with 20 years of experience, I feel that sudden increased resistance in the car is no simple matter. The most common cause is a malfunction in the braking system. For instance, if the brake caliper is stuck or the disc pads are adhered, the car feels like someone is pulling it from behind when it moves. Low tire pressure can also cause a sharp rise in resistance, making driving laborious and potentially damaging the rims. Issues in the drivetrain, such as a faulty clutch engagement or transmission hesitation, can make the car feel as if the handbrake is still on. Additionally, worn or rusted wheel hub bearings can lead to squeaking noises and increased fuel consumption. Remember, if you encounter this situation while driving, don't push through. Pull over safely first, check the brakes and tires yourself, and if anything seems off, head to a repair shop for a detailed inspection to avoid causing more significant damage.
