What Causes a Vehicle to Stall While Driving?
1 Answers
Reasons for a car suddenly stalling while driving: 1. Electrical circuit failure; 2. Short circuit in low-voltage lines causing intermittent stalling; 3. Component failure—vehicle may start initially but stall after a while, then restart and stall again; 4. Fuel system malfunction; 5. Issues with the ignition system or engine overheating protection system. If stalling occurs, assess the road conditions. If there is no emergency, gently apply the brakes to prevent rear-end collisions. As speed decreases, steer slowly toward the roadside lane. Maintain continuous brake pressure, gradually increasing force—avoid pumping the brakes, as this depletes remaining vacuum assist, making subsequent braking difficult. Once safely parked by the roadside, turn on hazard lights, set up a warning triangle, and call for towing assistance.
