hyundai ix35 highlander diesel problems

Hunting down Hyundai ix35 Highlander diesel problems? The Highlander 2.0 CRDi is generally stout, but like most modern diesels it sulks if you only do short, stop-start trips.

• DPF clogging on urban use: warning lights, limp mode; regular highway runs and correct low-ash oil keep it happy.
• EGR and intake soot build-up causing rough idle or hesitation; cleaning and software updates help.
• Boost leaks or a sticky turbo actuator leading to flat spots; check hoses and listen for whooshes or whistles.
• 6-speed auto shift flare or shudder when neglected; fresh fluid and updated calibration usually tame it.

Look for a full service history, smooth cold starts, and a long test drive at 100 km/h; walk away from anything smoky or chock-full of warning lights.
