Why does the Geely ESC warning light stay on and the car won't start?

ESC warning light illumination indicates a malfunction in the vehicle's ESC system, during which the electronic stability control system is not operational. The ESC warning light may be triggered by software system alerts, sensor failures, wiring short circuits, or even false alarms. It is necessary to visit a 4S dealership for specialized diagnostic equipment to perform troubleshooting and repairs. Introduction to ESC warning light: ESC stands for Electronic-Stability-Controller, which translates to Electronic Stability Control system for vehicle body. Main functions of ESC: The primary function of ESC is to provide enhanced stability and safety when the vehicle changes lanes or negotiates curves. Under normal driving conditions, the ESC system remains inactive. When the ignition is turned on, ESC activates, the warning light illuminates, and the ESC off indicator light comes on for approximately 4 seconds before turning off. When the ESC warning light remains constantly lit, it signifies a malfunction in the vehicle's ESC system, and the electronic stability control system ceases to function.
My Geely once had the ESC light on and couldn't start, which really worried me. Later, I found out it was a battery issue. If the battery is dead or aging, the ESC system requires stable power to operate, so insufficient power directly triggers the warning light and prevents the engine from starting. Common causes include low battery voltage, corroded or loose terminals; or a faulty starter, or broken sensors. I recommend checking the battery first: use a multimeter to test the voltage or simply charge it to see if it works. If that doesn't help, it might be a blown fuse—open the hood, locate the fuse box, and replace the one related to ESC. Other possibilities include a bug in the computer module that needs resetting, or a short circuit in the wiring harness. Never force-start the car to avoid further damage to the electronic systems; take it to a 4S shop immediately for professional diagnosis and repair.
As someone who frequently interacts with Geely owners, I know how frustrating it is when the ESC warning light comes on along with the car refusing to start—it's usually the electrical system acting up. For instance, when the battery is drained, the ESC module may trigger false alarms due to unstable voltage and might even prevent the car from starting as a linked response. Sometimes, a stuck starter relay or faulty sensors can cause a chain reaction of issues. The simplest first step is to check the battery condition—if it's fine, then inspect the fuses, especially those for the ESC and ignition circuits; also examine whether the wiring harness in the engine bay has aged or short-circuited. I once encountered a no-start situation with the ESC light on during cold starts, and replacing the battery fixed everything. Don't delay repairs—ESC failure increases the risk of losing control during emergency turns. Take it to a reliable repair shop for diagnosis; often, replacing a small part for just a few dozen dollars solves the problem.
