Affected Models: Sportage diesel, Niro

Symptoms:

• Stop-start failing to activate at stops.

• Battery draining faster than expected.

• Dashboard warnings for ISG or battery.

• Engine restarting sluggishly.

Common Causes:

• Faulty ISG sensors or software.

• Weak battery unable to support the system.

• Wiring issues disrupting signals.

• Design flaws in diesel ISG setups.

Impact:

• Reduced fuel efficiency without stop-start.

• Increased battery wear and replacements.

• Annoyance from an unreliable system.

Solutions:

• Software Update: Patch ISG firmware at a dealership.

• Battery Test: Replace weak batteries.

• Sensor Replacement: Fix faulty ISG sensors.

• System Disable: Turn off ISG if issues persist.

Estimated Repair Cost: AED 0-2,000 (software: AED 0-0; battery: AED 1,000-1,000; sensors: AED 1,000-2,000).

Prevention Tips:

• Maintain a healthy battery with regular checks.

• Avoid short trips that stress ISG.
