Why Is My Auto Start-Stop Not Working? (UAE-Specific Fixes)

If your vehicle’s auto start-stop system has suddenly stopped functioning — especially under the UAE’s extreme climate — you’re not alone. This guide dives into the most common reasons behind the failure and how to restore it.

Top Reasons Auto Start-Stop Stops Working

• Weak Battery: If your battery is below 12.4V, the system won’t activate.
• High UAE Temperatures: Systems often auto-disable in extreme heat to protect the engine.
• Brake or Clutch Sensor Fault: Faulty pedal sensors can disable the system.
• Incorrect Battery Type: Non-EFB/AGM batteries won’t support auto start-stop.
• Open Hood or Faulty Latch Sensor: Even slightly ajar hoods stop the system.

What You Can Do to Fix It

1. Fully charge or replace the battery with an AGM or EFB type.
2. Reset the system via battery disconnect or OBD2 scanner.
3. Check sensor diagnostics for the brake, clutch, or hood latch.
4. Follow our full reset guide here.
