On the 2015-2022 Renault Kadjar, the Kadjar diesel models experience frequent DPF regeneration failures, particularly in vehicles used primarily for short urban commutes. The regeneration process requires sustained load that urban driving cannot provide.

This issue also affects: Renault Captur, Renault Koleos

Common Symptoms

  • DPF warning light
  • Loss of power
  • Limp mode
  • Increased fuel consumption

How to Fix

Perform a forced regeneration via diagnostic tool. Incorporate a weekly 20-minute motorway drive at 2500+ RPM. Clean the DPF pressure differential sensor pipes.

Typical repair cost:$200 - $2,000

On the 2015-2018 Renault Kadjar, on Kadjars built at Palencia, Spain between 29 June 2015 and 2 March 2018, the child safety lock mechanism in the rear doors can work loose without the owner noticing. A parent who has set the child lock — and reasonably believes the rear doors cannot be opened from inside — can be carrying children in doors that will in fact open from the interior handle while the car is moving. Renault issued recall code 0D26; the EU classified the risk as serious under RAPEX alert 48/2020 (27 November 2020). Because the failure is silent, there is no dashboard indication and no way to tell the mechanism has released other than physically testing the door.

Common Symptoms

  • Rear door opens from the inside despite the child lock being engaged
  • Child lock lever feels loose or does not stay set

How to Fix

Check the VIN with a Renault dealer against campaign 0D26 — the inspection and repair are free. In the meantime, physically test each rear door from the inside with the child lock engaged before carrying children, rather than trusting the lever position: engage the lock, close the door, and confirm the interior handle will not release it. Do not rely on the child lock alone as the restraint strategy for younger passengers until the recall work is complete.

On the 2015-2016 Renault Kadjar 1.2 TCe 130 (H5Ft), early Kadjars with the 1.2 TCe 130 petrol engine (Renault code H5Ft, Euro 5) suffer excessive oil consumption caused by over-wide tolerances between pistons, rings and bores, letting oil pass into the combustion chamber. Owners commonly report needing more than a litre per 1,000 km. The burnt oil coats and damages the exhaust valves, and cases have escalated to sudden power loss at speed and complete engine destruction, with repair bills quoted up to EUR 10,000. The French consumer group that raised the alert covered Renault, Dacia, Nissan and Mercedes vehicles with the H5-series 1.2 TCe / 1.2 DI-t engine built from late 2012 to mid-2016; roughly 400,000 European cars carried the engine, including the Kadjar, Clio IV and Mégane III, with around 133,000 in France alone. Over 1,700 customers reported problems and several dozen French owners filed a criminal complaint at the Nanterre court alleging aggravated deception and endangerment. Renault disputed that all TCe A.2 engines are affected and attributed consumption to lubricants and usage conditions. Because the Kadjar launched in 2015, only its first two model years fall inside the defective production window; 1.5/1.6 dCi diesel and later 1.3 TCe Kadjars are unaffected.

Common Symptoms

  • Oil consumption above one litre per 1,000 km
  • Blue smoke from the exhaust
  • Low oil level warning between services
  • Sudden loss of power while driving
  • Misfire and rough running from damaged exhaust valves

How to Fix

Check oil level every fuel fill on an affected car — the failure mode is oil starvation and valve damage following unnoticed consumption, and it typically shows before 50,000 km while still inside warranty. Have a documented oil consumption test carried out by a Renault dealer (measured top-up over a set mileage) and open a warranty or goodwill claim on the strength of it, since consumption above roughly 0.5 l/1,000 km is not normal for this engine. Use only the specified Renault low-SAPS oil grade. Where consumption is already high, a piston and ring replacement is the real repair; topping up indefinitely ends in burnt exhaust valves and a scrapped engine.

Typical repair cost:$3,000 - $10,000
