📖Fiat Fullback Cross: lifestyle pick-up ruggedness with heavy-duty 4WD maintenance priorities

Fiat Fullback Cross (2017-Présent)

Introduced in 2017 as the flagship lifestyle version of Fiat’s one-tonne pick-up truck, the Fullback Cross brought aggressive styling featuring a bespoke matte black grille, integrated aerodynamic sports bar and black alloy wheels. Built on the heavy-duty ladder-frame architecture shared with the fifth-generation Mitsubishi L200, it bridges rugged site duties and adventure recreation, making rigorous Fiat Fullback maintenance essential to protect its sophisticated four-wheel-drive hardware and high-output diesel powertrain.

Under the bonnet sits Mitsubishi’s 2.4-litre 4N15 all-aluminium four-cylinder turbodiesel producing 180 hp and 430 Nm of torque, driven by an internal 2.4-litre turbodiesel timing chain. Power is directed through a 5-speed automatic gearbox and the advanced Super Select 4WD system with low-range transfer box, which includes a lockable Torsen centre differential and an electronic rear differential lock. The suspension features front double wishbones and heavy-duty rear leaf springs and heavy-duty dampers engineered to haul a 1-tonne payload while towing up to 3,100 kg.

Owner notes

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

Reassuring points

Reliability
  • Advanced Super Select 4WD system allows permanent four-wheel drive operation on dry tarmac as well as off-road.
  • Muscular 2.4-litre turbodiesel engine with 430 Nm of torque delivers exceptional 3.1-tonne towing capacity.
  • Proven ladder-frame chassis and Mitsubishi-engineered mechanical underpinnings provide outstanding durability.
  • Striking Cross exterior styling package with matte black detailing, sports bar and generous standard cabin specification.

Chronic weak spots

Keep an eye on
  • Super Select 4WD transfer box actuators: test engagement of all 4WD modes; sticking vacuum switches cause flashing 4WD dash lights.
  • 2.4-litre 4N15 diesel particulate filter: verify oil level on dipstick; frequent aborted DPF regenerations cause oil level rise above the 'X' mark.
  • 5-speed automatic transmission: test for smooth torque converter lockup and check fluid condition on heavily used towing vehicles.
  • Rear leaf spring suspension: inspect multi-leaf packs for cracked leaves, corroded U-bolts and worn shackle bushes.
  • Prop-shaft universal joints and centre bearing: check for play, vibrations at 80-100 km/h and missing grease on grease nipples.

Critical deadlines

Do not miss
  • Engine oil and filter change every 15,000 km or 12 months using low-SAPS C3 / C2 synthetic diesel oil (strictly monitor dipstick 'X' mark).
  • Differential oils (front and rear) and transfer box fluid replacement every 40,000 km or 24 months.
  • Automatic gearbox fluid replacement and propeller shaft universal joint greasing every 60,000 km or 36 months.
  • Brake fluid renewal, chassis rust protection inspection and leaf spring bush check every 24 months or 30,000 km.
