2021 Ford Ranger 2.0L Diesel · YR21 DTW

Both early 2.2 and 3.2 Duratorq diesels and early 2.0 EcoBlue engines suffer from injector failure. In 2015, Ford recalled nearly 14,000 UK Rangers for faulty injector batches that caused engines to cut out without warning while driving. Failed injectors suffer from high leak-back rates or internal nozzle jamming, leading to cylinder bore wash, uneven fueling, violent knocking, and melted pistons.

Manual T6 Rangers frequently suffer from stiff third-gear selection, worn synchromesh rings, and dual-mass flywheel rattle under heavy towing. Automatic variants (6R80 6-speed and later 10R80 10-speed) can exhibit harsh low-speed shifting, gear slip flare, and torque converter shudder. In addition, an official recall addressed gearshift selector cables that could unclip and foul the rear driveshaft.

The T6 Ranger features a fully boxed steel ladder chassis that readily traps road salt, farm slurry, and abrasive mud washed into internal frame openings. Without regular high-pressure flushing and cavity rustproofing, the metal corrodes from the inside out. Structural rot attacks the rear spring hanger brackets, spare wheel cross-member, and chassis rails around the fuel tank, causing catastrophic MOT structural failure.
