Jeep Cherokee MOT Failures
An analysis of 86,821 real DVSA MOT tests on the Jeep Cherokee — what fails, how often, and how that compares to every other car on UK roads. Generations covered: KL (2014–2021).
Where the Jeep Cherokee fails its MOT
The single biggest MOT failure point on the Jeep Cherokee is headlight fault — this model is 30 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 86,821 MOT tests, 2.03% of all Jeep Cherokee 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 suspension pin, bush or joint worn (11x the fleet average), tyre wear or damage (16x the fleet average), emissions failure (9.0x the fleet average), and transmission joint, belt or chain worn (37x the fleet average). These ratios compare the Jeep Cherokee'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 6 categories: Lights & Electrics, Suspension, Tyres, Exhaust & Emissions, Bodywork and others. If you're inspecting a Jeep Cherokee 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 Jeep Cherokee'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 Jeep Cherokee specifically, the DVSA data shows the most common failures at this mileage are headlight fault (30x the average) and suspension pin, bush or joint worn (10x). fluid leak (9.0x) and emissions failure (5.8x) 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 Jeep Cherokee specifically, the DVSA data shows the most common failures at this mileage are transmission joint, belt or chain worn (37x the average) and headlight fault (11x). suspension pin, bush or joint worn (8.2x) and tyre wear or damage (7.8x) 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 Jeep Cherokee specifically, the DVSA data shows the most common failures at this mileage are transmission joint, belt or chain worn (34x the average) and tyre wear or damage (16x). suspension pin, bush or joint worn (11x) and headlight fault (7.7x) also appear frequently.
The shift from headlight fault at lower mileages to transmission joint, belt or chain 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 Jeep Cherokee specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Transmission chain/belt excessive wear (KL) Major
The ZF 8HP transmission fitted to Cherokee diesel variants shows exceptionally high wear rates on internal chain components, with MOT data showing 34.3x the fleet average failure rate at 60-80k miles. Affects KL; typical independent garage repair cost is £3,500–£5,500.
Excessive fluid leakage - environmental hazard Major
Cherokee models show 12.0x the fleet average for excessive fluid leakage across multiple systems, with the issue worsening over time according to MOT data. Affects KL; typical independent garage repair cost is £200–£800.
Suspension pin, bush or joint excessive wear Major
Cherokee suspension components show 11.3x the fleet average wear rate, with the problem worsening according to MOT trends. Affects KL; typical independent garage repair cost is £200–£600.
Brake disc excessive wear/fracturing Major
Cherokee models show 4.8x the fleet average for brake disc fracturing or excessive weakening, with failures occurring across all mileage ranges including very low-mileage vehicles. Affects KL; typical independent garage repair cost is £180–£400.

What to check before buying a Jeep Cherokee
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Jeep Cherokee:
Lights & Electrics — check for headlight fault. Suspension — check for suspension pin, bush or joint worn. Tyres — check for tyre wear or damage. Exhaust & Emissions — check for emissions failure, fluid leak.
Beyond the MOT items, ask specifically about transmission chain/belt excessive wear and excessive fluid leakage - environmental hazard. These won't show up on a standard MOT but can be expensive to fix — repairs start from £3,500. 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.
