Renault Kadjar2020

Known issues

• DPF (Diesel Particulate Filter) clogging and regeneration failures, particularly in low-mileage urban driving; can trigger limp-mode and expensive forced cleaning or replacement (€400–€800)
• Electrical gremlins including battery drain, infotainment system crashes, dashboard warning light false positives, and window regulator failures
• EGR valve carbon build-up and occasional EGR cooler failures causing rough idle and emissions warning lights
• Damp ingress into door seals and trunk areas leading to water pooling and electrical corrosion; rear window seal leaks reported
• Turbocharger bearing wear at higher mileage (80,000+ km), sometimes accompanied by oil sludge in turbo passageways if oil changes neglected
• Transmission shudder and hesitation on 1.5 dCi models, especially during light-load motorway cruising; gearbox mapping software updates have had mixed success

Good for

• Genuine real-world diesel fuel economy in mixed driving (35–42 mpg typical), outperforming petrol rivals
• Spacious interior and practical boot; good visibility for family SUV use
• Diesel engines relatively bulletproof if serviced on schedule; low-speed torque suitable for towing
• Reasonable parts cost and independent garage availability across Ireland and UK
