Dodge Nitro MOT Failures
An analysis of 32,174 real DVSA MOT tests on the Dodge Nitro — what fails, how often, and how that compares to every other car on UK roads. Generations covered: KA (2007–2010).
Where the Dodge Nitro fails its MOT
The single biggest MOT failure point on the Dodge Nitro is electrical wiring fault — this model is 41 times more likely to fail on this item than the average car on UK roads. That makes it a significant weak point for anyone buying or owning this model. Across 32,174 MOT tests, 7.03% of all Dodge Nitro tests recorded this as a failure.
Lighting faults are usually straightforward to fix (bulbs, connectors, earth points) but can indicate deeper wiring issues on older cars. Check all lights including fog lamps, number plate lights, and dashboard warning lights.
Other notable weak points include parking brake efficiency below minimum requirement (121x the fleet average), suspension pin, bush or joint worn (114x the fleet average), parking brake efficiency less than 50% of the r... (38x the fleet average), and headlight fault (14x the fleet average). These ratios compare the Dodge Nitro's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.
The failures span 4 categories: Lights & Electrics, Brakes, Suspension, Wipers & Windscreen. If you're inspecting a Dodge Nitro before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.
How failures change with mileage
The Dodge Nitro's weak points shift as the car covers more miles. Understanding these patterns helps you know what to expect — and what to budget for — at each stage of ownership.
Under 60,000 miles
At this mileage, most failures are either design-related or caused by age rather than wear. Components like bushes and drop links may not have been replaced yet, and original-fit parts can deteriorate even on low-mileage cars that spend a lot of time sitting.
For the Dodge Nitro specifically, the DVSA data shows the most common failures at this mileage are suspension pin, bush or joint worn (114x the average) and electrical wiring fault (41x). parking brake efficiency less than 50% of the r... (38x) and parking brake inoperative on one side (27x) also appear frequently.
60,000 to 100,000 miles
This is where routine wear items start to show up. Brake components, tyres, and exhaust parts have done serious work by this point. Cars that have been well serviced will show fewer of these failures — this mileage band is where good maintenance really separates the well-kept from the neglected.
For the Dodge Nitro specifically, the DVSA data shows the most common failures at this mileage are parking brake efficiency below minimum requirement (121x the average) and suspension pin, bush or joint worn (24x). obligatory mirror or device slightly damaged or... (22x) and abs fault (20x) also appear frequently.
Over 100,000 miles
High-mileage cars accumulate failures across multiple systems. The key question isn't whether things will need doing — they will — but whether the car has been maintained well enough to keep on top of them. Look for a consistent service history and recent MOT passes with minimal advisories.
For the Dodge Nitro specifically, the DVSA data shows the most common failures at this mileage are suspension ball joints worn (154x the average) and parking brake efficiency below minimum requirement (33x). parking brake efficiency less than 50% of the r... (12x) and abs fault (8.7x) also appear frequently.
The shift from suspension pin, bush or joint worn at lower mileages to suspension ball joints worn at higher mileages is typical — early failures tend to be design or factory-related, while high-mileage failures reflect accumulated mechanical wear. A car that's been well maintained will usually dodge the worst of both.
Known issues beyond the MOT
An MOT only tests roadworthiness at a single point in time — it won't catch developing faults, intermittent problems, or issues that haven't yet reached the failure threshold. These are the issues that Dodge Nitro specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Suspension component corrosion and structural failure (KA) Dangerous
The Nitro suffers from catastrophic corrosion of suspension components, particularly control arms and subframe mounting points. Affects KA; typical independent garage repair cost is £800–£2,000.
Electronic parking brake failure (KA) Major
The Nitro's electronic parking brake system suffers from multiple failure modes including actuator motor failure, cable stretching, and control module faults. Affects KA; typical independent garage repair cost is £300–£800.
Suspension bush and joint wear (KA) Major
The Nitro experiences premature wear of suspension bushes and ball joints, with MOT failure rates 114.3 times higher than the fleet average at 40-60k miles. Affects KA; typical independent garage repair cost is £400–£800.
Wheel bearing failure (KA) Major
Wheel bearings on the Nitro fail at 21.8 times the national average, with peak failures occurring at 40-60k miles. Affects KA; typical independent garage repair cost is £200–£400.

What to check before buying a Dodge Nitro
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Dodge Nitro:
Lights & Electrics — check for electrical wiring fault, headlight fault. Brakes — check for parking brake efficiency below minimum requirement, parking brake efficiency less than 50% of the r..., parking brake inoperative on one side, abs fault. Suspension — check for suspension pin, bush or joint worn.
Beyond the MOT items, ask specifically about suspension component corrosion and structural failure and electronic parking brake failure. These won't show up on a standard MOT but can be expensive to fix — repairs start from £800. A specialist pre-purchase inspection is worth the investment on this model.
Always check the car's full MOT history for patterns — recurring advisories often become failures within 12 months. And verify the service history to confirm maintenance has been kept up to schedule. Enter any reg into our free car check to see the complete picture.

Dodge Nitro MOT FAQs
What are the most common MOT failures on a Dodge Nitro?
Based on 32,174 DVSA MOT tests, the most common failure is electrical wiring fault — at 41x the national fleet average. Other frequent failures include parking brake efficiency below minimum requirement and suspension pin, bush or joint worn.
Is the Dodge Nitro reliable based on MOT data?
The Dodge Nitro has 12 MOT failure categories above the fleet average. Specialists also flag suspension component corrosion and structural failure as a concern. A pre-purchase inspection and service history check are recommended.
What MOT failures should I expect at high mileage?
Above 100,000 miles, the Dodge Nitro most commonly fails on suspension ball joints worn and parking brake efficiency below minimum requirement. Under 60,000 miles, the main issues are suspension pin, bush or joint worn and electrical wiring fault.
