The PS warning light on your dashboard indicates a fault in the electric power steering (EPS) system, not the older hydraulic system. When it stays on while driving, it means the EPS has deactivated or is malfunctioning, leading to significantly heavier steering effort, especially noticeable during low-speed maneuvers like parking or navigating roundabouts. Common causes in the UAE's climate include EPS motor overheating from prolonged use in stop-and-go Dubai-Sharjah traffic, sensor failures due to dust and high under-hood temperatures, or electrical issues from a weak 12V battery, which is common after 2-3 years in summer heat. According to the RTA Dubai's vehicle inspection guidelines, a malfunctioning power steering system is a critical safety defect that can lead to test failure. Data from workshops in Abu Dhabi and Dubai shows that for popular GCC-spec SUVs like the Toyota Land Cruiser or Nissan Patrol, EPS-related warnings are among the top five electronic faults reported, often triggered after desert driving or exposure to dusty conditions. Ignoring this light is dangerous; a sudden loss of assistance on a highway like Sheikh Zayed Road can compromise control. The repair cost varies widely: a simple sensor recalibration might cost around 400 AED, while replacing the entire EPS rack on a luxury SUV can exceed 7,000 AED, including parts and labor at an agency workshop. For accurate diagnosis, a professional scan tool is required to read the specific fault code (e.g., C1515, C1525) stored in the car's computer.
