hyundai ix35 electrical problems Page 2

The Hyundai ix35 (2010–2015) can sprout a few electrical gremlins as it ages—nothing terminal, but enough to keep your multimeter busy.

• Battery drain or weak alternator/earth points causing random warning lights and slow cranking.
• Brake-light switch faults triggering ESC/ABS lights and gearshift lock issues (many were covered by recalls).
• Power window regulators and central locking actuators failing intermittently, often the driver’s door or tailgate.
• Blower motor resistor failure leaving only high fan speed—or none at all.
• Infotainment/Bluetooth dropouts and flickering reverse camera; sometimes fixed with software updates or head-unit replacement.
• Tailgate wiring loom fatigue leading to dead rear wiper/lock or number-plate lights.
• Ageing TPMS sensors (flat internal batteries) lighting the dash.

Start with the basics: test the battery and charging system, clean grounds, check fuses/relays, and scan for codes before chasing ghosts.

Then check Hyundai TSBs/recalls, and if symptoms persist, an auto sparky can pinpoint faults faster than guesswork—and cheaper than replacing half the car.
