Lexus IS 250/300h Common Problems Malaysia — 2GR-FSE Carbon & Hybrid Battery
IS 250 (2GR-FSE): bi-injection system (direct + port injection) reduces carbon buildup vs pure direct injection, but intake valve carbon still accumulates from 80,000–100,000 km. VVTL-i and VVT-i timing chain oil pressure critical — never miss oil change. IS 300h: 8-year/160,000 km hybrid battery warranty; if battery replaced at dealer, costs RM 10,000–18,000. Rear suspension lower arm bushings on GSE20/30 wear out at 80,000–120,000 km — common knock source.
