Your Car Died at a Malaysian Traffic Light? It's Probably Your Start-Stop System (and Battery!) | MyMechanic
Why Your Start-Stop System Just Said 'No'
Your car's start-stop system is pretty smart. It has a whole checklist of conditions it needs to meet before it'll shut down or restart the engine. If it refuses to restart, it's usually doing it for a good reason. The number one reason, by a mile, is:
A faulty battery sensor (it tells the car the battery is weak, even if it isn't).
A problem with the car's charging system (the alternator).
A sensor fault (like a door being open or a seatbelt unbuckled) that prevents the system from restarting.
Stuck at the Light? Here's Your Immediate Action Plan
This situation needs a calm and quick response.
Stay Calm & Hit the Hazards: Immediately let other drivers know you're stuck.
Try a Full System Reboot: Shift the gear into Park (P). Turn the ignition completely OFF. Wait for about 5-10 seconds. Then, press the brake and try to start the engine normally with the start button or key. This simple trick often works!
If It Still Won't Start: You've got a standard breakdown now. You need professional roadside assistance to get you out of that traffic lane safely.
