📖Dodge Durango III Facelift 2021+: ultimate muscle SUV evolution from V6 cruiser to 710 bhp Hellcat

Dodge Durango III (WD Facelift 2021) (2021-Présent)

Marking the final evolutionary zenith of the third-generation Durango, the 2021 refresh introduced a driver-centric Challenger-inspired cockpit, standard LED lighting and the headline-grabbing 710 bhp supercharged 6.2 Hellcat V8. Offering an exhilarating American antidote to mainstream luxury family hauliers like the Kia Sorento, it spans everything from economical V6 family transports to tyre-shredding supercharged behemoths. Meticulous Dodge Durango maintenance is imperative given the extreme performance and thermal demands involved.

While the familiar 3.6 Pentastar and 5.7 HEMI provide dependable everyday service, the SRT 392 and Hellcat models occupy an entirely different tier of mechanical complexity. The Hellcat demands particular vigilance regarding its dedicated low-temperature intercooler circuit, secondary coolant pump and heavy-duty supercharger drive belt. On Pentastar models, continuing vigilance is required around the engine valley oil cooler housing for oil or coolant weeping.

Owner notes

The reassuring points, known weak spots and deadlines you should not let slip.

Reassuring points

Reliability
  • Driver-orientated Challenger-inspired cabin features the intuitive 10.1-inch Uconnect 5 touchscreen and premium materials.
  • Breathtaking performance in SRT 392 and 710 bhp Hellcat variants delivers supercar acceleration with genuine seven-seat capacity.
  • Proven unibody platform offers excellent motorway cruising refinement and high towing capacity.
  • Wide range of powertrains accommodates sensible family road trips as easily as high-performance track-day hauling.

Chronic weak spots

Keep an eye on
  • Hellcat 6.2 supercharged cooling: intercooler electric water pump and supercharger belt condition must remain flawless - check for coolant weepage around the auxiliary radiator.
  • 3.6 Pentastar oil filter housing and cooler: plastic housing between cylinder heads can seep oil onto the bellhousing - inspect the valley with a torch after a brisk test drive.
  • SRT and Hellcat driveline stress: launch-control usage strains rear differentials, propshaft flex discs and half-shafts - check for clunks when toggling Drive and Reverse.
  • Brembo brake wear and tyre scrub: high vehicle kerb weight combined with immense power consumes tyres and two-piece brake discs rapidly - verify remaining pad and disc thickness.

Critical deadlines

Do not miss
  • Engine oil and filter renewal every 8,000 km or 12 months on Hellcat/SRT (MS-12633 0W-40) or 10,000 km on Pentastar/HEMI.
  • Supercharger drive belt and auxiliary cooling circuit inspection every 30,000 km on Hellcat models.
  • ZF 8-speed automatic gearbox fluid and integrated sump filter replacement every 60,000 km.
  • Brake fluid flush and mechanical caliper slider service every 20,000 km or 24 months.
