Common Problems with the
2016 Fiat Qubo

On 1.3-litre MultiJet turbodiesel models, the diesel particulate filter requires sustained high exhaust gas temperatures to burn off accumulated soot. Because many Qubos are purchased as town runabouts or Motability mobility vehicles undertaking repeated short trips under 3 miles, the engine never achieves active regeneration criteria. Soot accumulation triggers warning lights, engine oil dilution from unburnt post-injection diesel fuel, and limp-home mode.

The front MacPherson strut top mount bearings are exposed to road splash thrown up by the front tyres due to minimal wheelarch arch lining protection. Water and road grit wash away the factory grease, causing the internal ball bearings to corrode, bind, and seize. This leads to heavy, groaning steering at low speeds, twanging noises as the coil spring binds and jumps, and eventual fatigue fracture of the front coil spring.

The exterior front door handles on the Qubo use a cast plastic pivot arm that connects the pull handle to the door lock release rod. The plastic hinge fatigues and snaps when pulled firmly on cold mornings or when door seals stick to the frame. When broken, the handle flaps loosely in the door skin without unlatching the door, forcing occupants to enter from the passenger side or lower the window to open from the inside.
