Why Doesn't the Rear Wheel Move After the Car Has Been Parked for a Long Time?

If the rear wheel doesn't move after the car has been parked for a long time, it may be due to a dead battery, oxidized oil, or a flat tire. Here are the specific reasons: 1. Dead battery: The battery may be dead and unable to start the car. This is because the battery still undergoes "sleep discharge" even when the car is turned off. 2. Oxidized oil: For vehicles that haven't been driven for an extended period, if the oil isn't changed regularly, it can easily oxidize and deteriorate, losing its ability to lubricate and cool effectively. 3. Flat tire: Long periods of inactivity can cause the tire pressure to drop. Additionally, when parked for too long, the pressure on the tires is concentrated on one spot, which may also lead to tire deformation over time.
I've encountered this too! When a car sits idle for too long and suddenly won't move, it's usually because the brake discs and pads have rusted and stuck together. Especially when parked outdoors on rainy days, cast iron brake discs exposed to moisture can rust solid in just a few days. My neighbor's car had this exact issue last time - forcing it to move actually tore the brake pads. Here's a folk remedy: shift into reverse and move forward a few centimeters, then shift into drive and move backward a few centimeters. Repeat this a few times until you hear a 'clunk' sound indicating they've loosened. If it still won't budge, absolutely don't force it - the safest option is to have a mechanic remove the wheel and tap it loose. Forcibly towing might damage the suspension.
