Lexus IS 250/300h/350 Power Steering – EPS System Malaysia
All IS variants use Electronic Power Steering (EPS) — no power steering fluid required. EPS is maintenance-free under normal use. At high mileage (120,000 km+), check for steering rack wear (noise or looseness at straight ahead). EPS rack replacement costs reconditioned. If the steering feels heavy or gives a power steering warning, scan for EPS module fault codes first.
Lexus IS Power Steering
- IS uses Electric Power Steering (EPS) — no hydraulic fluid to change; steering feel is tuned electronically
- EPS fault symptoms: heavy steering at low speed, inconsistent assist, steering warning light — diagnose with Techstream
- EPS rack replacement: rare but possible on high-mileage IS — use a workshop that can source genuine Lexus/Toyota EPS rack
- Steering wheel vibration: usually wheel balance or suspension — not EPS; diagnose systematically
