What are the reasons why the rotary knob of Baojun 510 cannot shift gears?

The reasons why the rotary knob of Baojun 510 cannot shift gears are as follows: 1. Transmission failure: The internal pawl mechanism may be stuck. For automatic transmissions, the P gear also serves as the vehicle's parking gear. In this case, a mechanic should be called to inspect and troubleshoot the issue; 2. Car battery is dead: Generally, if the car battery is dead, all electrical components in the car will not function. Please check if other electrical components in the car are receiving power; 3. Transmission is not receiving power: This type of fault is relatively rare because modern automatic transmission cars use electronic shifting controlled by a computer. If there is an issue with the internal circuit of the transmission, faults such as the gear not receiving power or the gear indicator light not turning on may occur.
I've encountered this situation before. When the gear shift knob of the Baojun 510 gets stuck, it's mostly due to the electronic system acting up. Last time my car suddenly couldn't shift gears, and after struggling for a while, I found out it was due to poor contact in the brake light switch—because the rotary gear shift must be activated by stepping on the brake to send the signal. Additionally, dust can easily get inside the knob, causing contact oxidation. Disassembling it and spraying some WD-40 can solve the problem. Here's a lesser-known fact: when the battery voltage drops below 11V, the electronic gear shift will enter protection mode. The most troublesome issue is a malfunction in the gear shift control module, especially after driving through water on rainy days, which can easily cause a short circuit. I recommend first checking if the brake lights are functioning properly, then try disconnecting the negative terminal of the car battery for ten minutes to reset the system. If it still doesn't work, you'll have to visit the 4S shop to read the fault codes. Remember to keep the knob area dry and clean regularly, and avoid forcing the gear shift when the steering wheel is locked.
Having driven the Baojun 510 for over three years, I've encountered knob sticking issues three times. The first time was when car wash foam seeped in, causing contact adhesion—it took two days of sun exposure to recover. The second incident was more amusing: my child stuffed a sticker into the knob gap, jamming the rotating shaft. The most severe case was when the micro motor in the gearshift assembly burned out; upon disassembly, I saw the carbon brushes had worn away completely. These electronic shifters are far more delicate than traditional gear levers. Special precautions: avoid shifting immediately after a cold start—wait for the self-check to complete; aftermarket audio modifications can easily interfere with control circuits; always return to P before shutting off the engine, or the locking mechanism may misalign. If stuck, don’t force it—simultaneously pressing the brake and accelerator for ten seconds can forcibly disable protection mode. Of course, blown fuses or transmission sensor failures can cause similar issues—remember to wear anti-static gloves when troubleshooting yourself.
