Italian-styled compact crossover with Jeep underpinnings
Launched in the UK in April 2015 from £14,595, the 500X shares its platform with the Jeep Renegade. It competes against the Nissan Juke and Renault Captur. Early cars with 1.4 MultiAir and 1.6 E-torQ engines start from £6,000, while post-2018 facelift models with FireFly engines range from £10,000-£16,000. MOT pass rate of 84% is above national average, but electrical niggles and DCT gearbox issues tarnish the ownership experience.
We track 5 known issues across the Fiat 500X range, with 1 classified as significant. Knowing which variants and configurations to approach with caution can save you from expensive surprises after purchase.

334 (2014–2023) — Petrol options included the 1.0 TwinAir Turbo, 1.3 T4, 1.4 MultiAir, 1.6 E-torQ, with 1.3 MultiJet II, 1.6 MultiJet II, 2.0 MultiJet II on the diesel side. We track 5 known issues on this generation, with 1 classified as significant. The most significant concern is Door mechanism failure (£180–£320 to address).
The door handles and internal latch mechanisms on the 500X are prone to premature failure, particularly on the 1.4 and 1.6 petrol variants around 40,000-60,000 miles. The plastic components in the door handle assembly become brittle and the internal cables can stretch or snap, preventing doors from opening or closing properly.
A failed door mechanism can trap occupants inside the vehicle or prevent the door from latching securely while driving. Complete handle failure typically requires replacement of the entire door handle assembly and internal mechanism. Each door can cost £200-400 to repair depending on which components have failed.
Check panel gaps are even and consistent all the way around the car. Look for signs of repainting — overspray on rubber seals, mismatched paint texture or colour differences between panels. Open and close all doors, the boot and bonnet to check alignment.
The rubber gaiters protecting the steering rack are failing prematurely across all engine variants of the 500X, with MOT data showing failure rates up to 51.2 times the national average. These protective boots prevent dirt and water from contaminating the steering rack mechanism. Failure can occur from very low mileages and appears to be a design or material quality issue rather than normal wear.
Failed gaiters allow dirt and moisture to contaminate the steering rack, leading to premature wear of the internal mechanism. If left unaddressed, this can progress to steering rack failure requiring complete replacement. Early gaiter replacement is relatively inexpensive but rack replacement can cost £800-1,200.
During the test drive, check the steering for excessive play, vibration or pulling to one side. Listen for groaning or whining when turning the wheel at low speed. Power steering fluid level and condition should be checked on hydraulic systems.
The lambda sensors monitor exhaust gas composition to maintain optimal fuel mixture. Failure causes the engine management light to illuminate and affects fuel economy and emissions performance.
A failed lambda sensor causes increased fuel consumption, higher emissions, and potential MOT failure. The engine remains driveable but may run less efficiently. Sensor replacement is typically straightforward on this engine with sensors accessible from above.
Check all electrical functions systematically: windows, mirrors, lights, infotainment, heated seats, air conditioning. Look for any warning lights on the dashboard. A diagnostic scan before purchase can reveal stored fault codes.
The 500X shows suspension bush wear at 42.3 times the national fleet average, affecting all engine variants but particularly the 1.6 petrol around 40,000-60,000 miles. The rubber bushes in the suspension arms and anti-roll bar links deteriorate prematurely, causing handling deterioration and MOT failure.
Worn suspension bushes cause deteriorating ride quality, increased tyre wear, and reduced handling precision. The car remains safe to drive but handling becomes progressively worse. Complete suspension bush replacement can be costly if multiple components are affected simultaneously.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.
This typically relates to emissions system components such as the EGR valve or diesel particulate filter rather than core engine problems.
Engine management faults on diesel variants can limit performance and cause MOT failure for emissions. Many faults are related to the exhaust aftertreatment system rather than engine internals. Diagnosis requires OBD scan tools and repairs can range from software updates to component replacement.
Check all electrical functions systematically: windows, mirrors, lights, infotainment, heated seats, air conditioning. Look for any warning lights on the dashboard. A diagnostic scan before purchase can reveal stored fault codes.

Based on 170k real DVSA MOT tests, the Fiat 500X fails more often than average on several items. The biggest outlier is body panel damage at 60x the fleet average, followed by track rod ends worn (22x).
When viewing a specific car, check its MOT history for recurring advisories in these categories. See the full Fiat 500X MOT failure breakdown for data at every mileage point.
Routine servicing (oil and filter change every 12k miles) typically costs £80–£120 at an independent garage.

The Fiat 500X is a reasonable used buy provided you check for the issues outlined above. None of the problems we track are insurmountable, but they do reward buyers who inspect thoroughly and verify the service history before committing. 2019-2021 facelift models with the 1.0 FireFly petrol and manual gearbox are the safest choice — they avoid the troublesome DCT automatic and the older MultiAir valve issues. Avoid pre-2018 cars with the 1.4 MultiAir and automatic gearbox combination. The 1.3 FireFly Turbo is only available with the DCT, so stick to the 1.0 manual. Cambelt replacement every 5 years or 72,000 miles — budget £500.
