Used Toyota Fortuner in Chennai

— Post-2020 BS6 Fortuner diesels have a DPF that traps soot. If the car is primarily used for short city trips (under 15 km), the DPF doesn't get hot enough to regenerate and clogs. Symptoms include a DPF warning light on the dashboard, reduced power (limp mode), and excessive white smoke on startup. A clogged DPF replacement at Toyota costs ₹80,000-1,20,000. Check the instrument cluster for any DPF-related warnings and ask about the car's typical usage pattern — highway-heavy cars rarely have DPF issues.

— The 2.8L diesel's variable geometry turbo uses an electronic actuator that can fail, especially on cars with 70,000+ km. Symptoms include loss of power above 3,000 RPM, a whistling/whining noise from the engine bay, and a check engine light. The turbo actuator alone costs ₹25,000-35,000 to replace at Toyota. If the turbo itself is damaged, the bill climbs to ₹1,50,000+. During the test drive, do a hard acceleration in 3rd gear from 2,000 RPM — the boost should come on smoothly without hesitation or unusual noises.

— The Fortuner uses a body-on-frame construction. A serious front or rear impact can bend or crack the ladder frame, which is extremely expensive and sometimes impossible to repair properly. Look under the car at the main frame rails — they should be straight with no visible welds, patches, or misalignment. Check the frame at the front cross-member and rear bumper mounting points. Any frame welding means the car was in a serious accident. Walk away regardless of price.
