Fiat 500X
The 1.6 MultiJet is technically mature and delivers good mileages if the timing belt is changed on schedule. A production defect with undersized crankshafts affected early Tipo examples from 2016. Blocked DPF and low-rpm hesitation are the most common everyday issues.
Dull Duty
1.6 diesel in the Tipo or 500X: mileage accumulator without emotion. DPF, injector and dual-mass flywheel problems make the already joyless drivetrain a risk.
Engine Weaknesses 5
Early Tipo examples from 2016 production had incorrectly short crankshafts fitted. These can lead to complete oil pressure loss and total engine damage. Fiat instructed dealers to completely replace the affected engines.
Symptoms: Engine warning light, oil pressure warning, knocking from engine, sudden engine stop
The 1.6 MultiJet is a timing belt engine with interference principle. Exceeding the replacement interval of 120,000 km or 6 years risks belt failure with catastrophic engine damage.
Symptoms: Sudden engine stop, engine won't start again, metallic noises when attempting to start
Individual vehicles showed early failure (under 20,000 km) of the heat exchanger with oil entering the cooling system. Fiat recognised the problem and replaced the cooler as a goodwill gesture.
Symptoms: Temperature gauge rises rapidly, loss of heating capacity, oil visible in coolant reservoir
The EGR valve of the 1.6 MultiJet tends to carbon up and delays torque build-up. Typically manifests as poor throttle response up to approximately 2,000 rpm.
Symptoms: Delayed throttle response, engine hesitant to rev, sporadic power loss
During active DPF regeneration, the engine judders heavily at low revs, especially below 2,000 rpm. This behaviour is often interpreted by drivers as an engine fault.
Symptoms: Heavy juddering below 2,000 rpm, poor throttle response, fuel consumption display drops in steps
Vehicle Weaknesses 9
Recall action on the Fiat 500X (334) for faulty rear seatback locking. Rear seats could fold forward in an impact.
UConnect infotainment and parking sensors on the Fiat 500X (334) show frequent malfunctions. Bluetooth disconnects, false parking sensor warnings and system hangs.
Front control arms on the Fiat 500X (334) wear early and are a known weak point at MOT inspections.
Door seals on the Fiat 500X (334) let in wind noise at higher speeds or develop leaks.
The braking system on the Fiat 500X (334) shows above-average wear. Brake calipers can seize.
The exhaust system on the Fiat 500X (334) is prone to corrosion, especially at the rear silencer and intermediate pipes.
The AC condenser on the Fiat 500X (334) sits exposed and is vulnerable to stone chip damage.
Tie rod ends on the Fiat 500X (334) wear out and cause MOT defects.
Interior plastics on the Fiat 500X (334) rattle and creak, especially in the instrument panel and door cards.
