Chrysler Jeep Grand — MOT statistics 2024
The Chrysler Jeep Grand failed 40.3% of 2,963 first MOT attempts in 2024 ("first-time", excluding retests). Adjusted for the age of the fleet, its initial-failure ratio is 96.5 (100 = expected for its age profile). This car is too close to call — statistically indistinguishable from normal for its age. Small sample — treat with care.
Age-adjusted peer: Volkswagen Jetta (index 96.5) — the two published results are 0.0 index points apart.

If a car like this fails, does it fail again?
A failure rate does not say whether a failure is a one-off or the start of something. This follows the same vehicles into their next ordinary MOT a year later — retests after a repair are excluded, because they follow a failure by definition. 2019-2024.
| After this year's test | Fails next year | Vehicles followed |
|---|---|---|
| It failed | 36.2% | 2,728 |
| It passed | 35.1% | 11,085 |
A failed test does not clearly change next year's odds here (36.2% against 35.1%): the difference is within the margin of error. The failure most likely to come back is lamps, reflectors and electrical equipment — 33.6% of those vehicles fail again next year. Some of this is the vehicle and some is the owner: a car that was let go once tends to be let go again. One caveat: a car that fails may be sold or scrapped rather than tested again, so these figures describe the vehicles that came back.
Adjusted for how much these are actually driven
The headline index adjusts for the fleet's age. Wear, though, follows mileage: a three-year-old taxi and a three-year-old garage queen sit in the same age band. These two rows compare every car with vehicles of the same age, and then with vehicles of the same age and the same annual mileage, 2019-2024, on 27,494 tests. Both stand on the six-year corpus so they are measured on identical data — compare them with each other, not with the headline index above, which is measured on 2024 alone.
| Standardised for | Index | Reading |
|---|---|---|
| Age only | 98.1 | fails less often than expected |
| Age and annual mileage | 93.8 | fails less often than vehicles driven as much |
| Share doing under 3,000 miles a year | 2.5% | a normal spread of use |
Mileage matters here: matching on how much these are driven moves the figure by 4.3 points — this fleet works harder than the vehicles it is measured against, so the age-only view penalises it — but it does not change which side of normal the car sits on. One limit to keep in mind: mileage is partly a result of how often a car breaks down — one that spends weeks in the workshop covers fewer miles — so the mileage-matched figure can understate a real weakness. Tests with no usable odometer reading are left out of it.

Is a Chrysler Jeep Grand ULEZ compliant?
The share of classifiable 2024 Chrysler Jeep Grand MOT tests likely ULEZ compliant by first-registration date is 6.5%.
Based on 2,806 classifiable initial MOT tests. This describes the tested fleet, not a specific car. MOT data do not record Euro class, so likely compliance is inferred from fuel and first-registration date. For the only authoritative answer, check the registration with TfL's official ULEZ checker.

Takeaway: the spread between best and worst month is 4.9 percentage points — noticeable seasonality. Seasonality partly reflects registration-date clustering, not weather.
Before reading the shape: most of it is not about cars. Britain changes its registration plates twice a year, and 18.9% of these cars were first registered in March with another17.1% in September — 36% in two months against the 17% an even spread would give. An MOT falls due three years after first registration, so the buying calendar becomes the testing calendar. That shapes how many cars are tested each month — not how often they fail: the busiest months here are not the worst ones, so read the failure line on its own and the volume behind it separately.

The best build year here is 2012 and the weakest is 2010. Comparing build years sounds simple and is not: within a single year of testing, a car's build year and its age are the same number, so a naive comparison of years is a comparison of ages wearing a disguise. Each year below is measured against the same model at the same age in other cohorts, across six years of testing — 3 of 11 years come out distinguishable from their own model's age norm.
Two limits worth knowing before you act on this. Age, test year and build year are locked together by arithmetic, so the test-year effect is taken from the observed national failure level of each year rather than estimated — it is an adjustment, not a solution.
Chrysler Jeep Grand MOT repair costs
The MOT-failure repair budget per test runs from £146.08 to £277.55, against £54.85 for the test itself.
bigger number = costs morepounds per test, MOT-failing faults only
| Component | Fails per 100 tests | Typical repair | Its price | Contribution |
|---|---|---|---|---|
| Lamps, reflectors and electrical equipment | 38.6 (nat. 18.09) | Battery replacement (standard 12V lead-acid) | £140 | £54.04 |
| Brakes | 32.8 (nat. 11.25) | Front brake pads (parts + labour, typical hatchback) | £150 | £49.20 |
| Suspension | 23.8 (nat. 15.36) | Suspension coil spring (single corner) | £180 | £42.84 |
Multiply how often each component fails on this model by what that repair usually costs, and you get the amount an owner should expect to budget per test for MOT-failing faults only — roughly £146 to £278, on top of the test fee itself. It is a budgeting figure, not a quote: the spread between a set of pads and a set of discs is most of the range.
Prices are modal quotes from a hand-kept catalogue of published UK garage guides — we do not scrape the booking sites, their terms forbid it, so this list is short and updated by hand with a source and date against each line. Each line prices one typical repair in that group, not a full remedy, and only groups our catalogue actually covers are counted. The contrast worth noticing is the second card: the legal maximum for the test has been £54.85 since 2010, while the repairs it uncovers have followed inflation the whole time.
For scale from a different direction: Warrantywise, which sees used-car warranty claims rather than test failures, puts the average claim at £2,052 across the ten highest-claim models it ranks and £539 for Honda, the lowest-claim make in its index (Warrantywise index 2026, 1.6 million claims, cars aged 3–15). Those sit an order of magnitude above the figures in this table, and the gap is the point: a warranty claim is a gearbox or an engine, which almost never fails an MOT, while the faults that do fail one are corrosion, lamps and tyres, which no warranty pays for. The two numbers answer different questions and neither replaces the other.

No single year stands out as the point where this model starts costing more: the year-to-year steps in its failure rate are too small or rest on too few tests to name one (D1 rule: a step is named only with at least 2,000 tests on both sides and a jump above 3 percentage points).
Repair spend uses the same modal prices as the section above, so it inherits the same limits: one typical repair per component group, not a full remedy. Downtime is the gap between the failed test and the passed re-test, which is the window a vehicle is legally off the road.
Chrysler Jeep Grand rust problems: where they corrode
Age-standardised corrosion susceptibility stands out at 2.23×, against 1.00× for the national age-standardised rate.
above 1.0× = rusts more than averagebelow 1.0× = rusts less
This Chrysler Jeep Grand fails on corrosion far more often than average once age is held constant, and its owners live in areas that are gentler than most for the models we publish. Those two point in opposite directions, which is the informative case: it rusts more than average despite living in gentler places, so the cause is the car, not the postcode.
Corrosion is the one failure mode that is as much about geography as about the car. We keep the two apart on purpose: a model can look rusty simply because it is popular in Scotland, and a model can look clean simply because it is bought in Surrey. Blending them into a single score would hide which of the two is doing the work.
Exposure is this model's tests weighted by an area corrosion index built from frost days, salt load and distance to the coast — the composite validated at r = 0.42 against corrosion defects we actually record. It is published as a rank, not a raw score, because every mainstream model skews towards low-corrosion areas for the simple reason that most of Britain's cars are in the south. Susceptibility is standardised to the national age profile, so an old fleet does not get labelled a rusty model.
Does a Chrysler Jeep Grand advisory become a failure?
Lamps, reflectors and electrical equipment are highest at 31.7%; Non-component advisories are lowest at 0.0% — the gap is 31.7 percentage points.

| Component | Fails next time | Typical lead time | Miles of warning | Advisories tracked |
|---|---|---|---|---|
| Lamps, reflectors and electrical equipment | 31.6% | 12.1 months | 3,994 | 1,068 |
| Brakes | 20.9% | 12.1 months | 4,276 | 6,311 |
| Suspension | 18.3% | 12.1 months | 4,647 | 6,214 |

| Steering | 11.1% | 12.1 months | 4,586 | 1,365 |
| Tyres | 7.5% | 12.1 months | 4,333 | 4,226 |
| Noise, emissions and leaks | 6.2% | 12.1 months | 3,875 | 2,844 |
| Identification of the vehicle | 3.0% | 12 months | 5,112 | 638 |
| Non-component advisories | 0.0% | — | — | 2,333 |
This is the question an advisory note actually raises, and it needs six years of test history to answer. We followed the same vehicles from one MOT to the next across 2019–2024 and measured how often a component that was merely advised came back as a genuine failure at the next test.
Read it as a budgeting horizon, not a prophecy: the most likely component above turns into a failure for about 32 in 100 cars, and the median gap is 12.1 months and roughly 3,994 miles. The rest were repaired, sold, scrapped, or simply held. Rows with fewer than 500 tracked advisories are not shown.
What will fail next on a Chrysler Jeep Grand?
Lamps, reflectors and electrical equipment after a failure at age 15-19 are highest at 29.4%; Visibility after a passed at age 6-8 is lowest at 4.4% — the gap is 25.0 percentage points.

The same chains, cut differently: given a car's age and how its last test went, which component most often causes trouble at the following one.
The pattern that repeats across every family: a failure at one test roughly doubles the chance of a failure on the same component at the next one, and an advisory sits about half-way between a clean pass and a failure. Age bands in years; probabilities are per car, not per defect item.
Chrysler Jeep Grand ownership: what six years of MOTs show
The ten-day re-test pass rate is highest at 68.5%; The later re-test pass rate is lowest at 8.2% — the gap is 60.3 percentage points.
higher = larger sharecompare shares in percentage points
Failing is usually a same-week event, not a disaster. Of 7,478 failures followed through to their re-test, 23.28% were repaired and passed the same day and 68.49% within ten days; the median gap is 2 days. 23,184 defect items were cleared in the process.
Per mile driven, not per year. Dividing failures by the miles that actually went onto the odometers between consecutive tests gives 0.695 failures per 10,000 miles, on a median of 4,063 miles a year across 5,645 chains. This is the number to compare between models — an annual rate quietly rewards cars that barely leave the drive.
Two populations hide inside one model. 19.98% of these cars strung together three or more tests with nothing recorded at all, while 47.03% carried the same advisory three times or more — the same fault, noted, ignored, noted again. When you buy used you are buying one of those two histories, and the MOT record shows which.
Odometer anomalies: 5.872% of 5,671 chains show a reading lower than the previous test, with a median drop of 57,761 miles. We call this an anomaly and not fraud on purpose — instrument swaps, imports, unit mix-ups and keying errors all land in the same bucket. Obvious typos (drops under 100 miles or over 90% of the reading) are already excluded.

DVSA lists 61 safety recall campaigns for the Chrysler Jeep Grand, covering roughly 236,528 vehicles in total. A recall is the manufacturer fixing a fault for free, so an open recall on your car costs nothing to clear.
Counter-intuitive, and measured on our own data: across the 25 families published here, more recalls go with a lower MOT Risk Index (r = −0.52). Heavily recalled models are not worse cars in the test bay — an active manufacturer removes the fault before it becomes an MOT failure.

- What is the Chrysler Jeep Grand first-time MOT pass rate?
- 59.7% of first attempts passed in 2024 (2,963 tests). This is the first-time figure: retests after repair are excluded. Basis: first-time, excluding retests.
- Why does this number differ from other sites?
- Other sites often report a pass rate that includes retests or counts all attempts. Our 40.3% figure is the first-time initial failure rate, using 2,963 primary tests as the denominator (first-time, excluding retests). The age-adjusted MOT initial-failure ratio 96.5 is shown separately because raw rates compare fleet age as well as cars.

Data details & how to cite
Scope: class-4 vehicles (cars), initial tests only, outcomes pass / fail / fixed-on-the-spot at the station (PRS counts towards the failure rate — the defect was present at arrival). Index = observed initial failures ÷ failures expected for this fleet's exact age profile, ×100; margin of error is a 95% confidence interval. Covers ALL generations together — a 3-year-old and a 15-year-old are very different cars; a generation split is on the roadmap.
