High oil consumption, burnt exhaust valves, engine failure (2012-2018)
Signs: Oil level drops fast (can exceed 1 L per 1,000 km), low oil warning, blue smoke, loss of power, misfire or engine noise; often unnoticed until damage is done
Fix: Check the dipstick every fill-up; ask a Renault/Dacia/Nissan dealer by VIN for the ECU recalibration and an oil consumption test and file a goodwill request with the service history; if consumption stays high, the engine needs rings/pistons and valve work or a replacement engine
