ESC repair refers to a malfunction in the vehicle's Electronic Stability Control system, which can lead to accidents when turning or driving on rough roads. Below is a partial introduction regarding headlight water leakage repair: Minor water ingress: For relatively minor cases of water inside the headlight, there is no need to worry excessively. After the headlights are turned on for a period of time, the moisture will be expelled through the vent tube along with the heat, which generally does not damage the headlight or electrical circuits. Severe water ingress: In cases of severe water ingress, the headlight cover needs to be removed to inspect the headlight surface for any damage or potential leakage points. If any abnormalities are found, it is recommended to replace the headlight rear cover seal and vent tube.

I once encountered the ESC light turning on while driving, and the car felt floaty when turning, especially prone to losing control on rainy days. I took it to the 4S shop for inspection, and the mechanic said it might be due to dirty wheel speed sensors or loose wiring harness connectors. If the sensors are aged or damaged, it could cost a few hundred to replace them. If the control module is faulty, the repair cost could exceed a thousand. Neglecting such issues greatly compromises driving safety, as ESC helps prevent accidents caused by wheel slippage. I recommend getting it checked by professionals immediately when the ESC warning light comes on—don’t delay to save trouble. During routine maintenance, remind the technician to inspect these sensors to reduce unexpected failures. That experience taught me how crucial these details are.
