What Causes the ESP Failure in Xpeng Motors?

When the ESP light on the dashboard illuminates, it indicates a potential failure in the Electronic Stability Program system. Fault Indications: In the automatic transmission control system: ABS (ESP) (CAN) speed fault (P, permanent fault); In the engine control system fault information: Communication fault with automatic transmission (P, permanent fault). ESP Components: ESP consists of three main parts: sensors, actuators, and the electronic control unit. Sensors typically include wheel speed sensors, steering angle sensors, lateral acceleration sensors, yaw rate sensors, and brake master cylinder pressure sensors. Actuators generally comprise traditional braking systems and hydraulic modulators, while the electronic control unit works in conjunction with the engine management system to intervene and adjust engine power output.

Last year, while driving the XPeng G3, the ESP light came on. It happened after going uphill on a mountain curve. I suspect it might have been due to the wheel speed sensor being clogged with mud, causing a signal error and triggering a false alarm from the system. XPeng is an electric vehicle, and sometimes the high-voltage battery system can interfere with signals, leading to faults. It could also be a software bug, such as an incomplete OTA update or a logic error. The manual suggests checking if the wheel speed sensor is dirty or if the wiring connections are loose—simple steps to troubleshoot. Later, I went to the service center, and they used a computer to reset the system and clear the fault code. Remember, ESP protection is crucial for preventing skids during turns. If the light comes on, it's best to slow down and pull over safely, avoiding sudden steering maneuvers to prevent accidents. Regular maintenance, including cleaning the sensor area, can help avoid many issues.

As an automotive enthusiast, I've researched ESP malfunctions. The ESP system in Xpeng vehicles relies on sensors and electronic control modules. Common causes include contaminated or damaged wheel speed sensors leading to signal interruption, or system software errors such as communication delays triggering false alarms. In intelligent electric vehicles, high-voltage interference is more prone to occur, where unstable battery voltage can transmit noise affecting stability control. It's recommended to first use diagnostic tools to read fault codes for precise identification rather than disassembling blindly. From the manual, I learned that regular firmware updates can prevent many software-induced failures. When the system malfunctions, driving feels noticeably unstable and emergency braking becomes hazardous. Xpeng service centers can typically resolve issues quickly through sensor calibration or replacing minor components.

I just started driving my Xpeng not long ago, and the ESP light suddenly flashed while driving in the city, which was quite nerve-wracking. A friend explained it might be a temporary false alarm from the system, like slippery or bumpy roads. The simplest solution is to pull over, turn off the engine, wait a few minutes, and restart—sometimes the light will go off. If that doesn’t work, it could be a faulty sensor or a blown fuse, and you should get it fixed immediately. For safety, drive slower and avoid sharp turns. An ESP failure reduces cornering protection, so extra caution is needed, especially in rainy conditions. In short, don’t delay—seek professional help to resolve it.
