Rover 45: MOT pass rate and reliability data

The Rover 45 fails its first MOT more often than the average UK car, by 14.6 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 2,021 individual Rover 45 tests. Nothing here is an estimate or a survey.

The numbers

What this means if you are buying one

A 62.1% first-time pass rate means roughly 38 in every 100 Rover 45s presented for MOT fail on the first attempt. That is worse than average, so budget for remedial work and treat a fresh 12-month MOT as a genuine selling point rather than a given. The average Rover 45 tested had covered 78,561 miles and was built around 2003.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. The Rover 45 sits 14.6 points below the national average, ranked 1,913 of 2,005 models. On one bought as repairable salvage, assume the mechanical side needs more than the visible accident damage, and pad your repair estimate accordingly.

Before you bid: run the lot through the analyzer, check the car's own record, check the mileage, decode the VIN, and if it carries a marker use the write-off value calculator. Or compare it against another model.

Looking at a specific Rover 45 rather than the model in general? The free check covers its MOT and mileage history, and the full HPI report confirms the insurance write-off category, outstanding finance and whether it is recorded stolen, from licensed data for 5 credits. Already own one that has been damaged? Work out whether fixing it beats selling it with the repair or scrap calculator, and see recorded closing bids for damaged Rover 45s at UK salvage auction.

Most common MOT failures on a Rover 45

2. Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced, 4% of tests (9.71x the national rate for this defect)
3. An SRS malfunction indicator lamp (MIL) indicates a system malfunction, 2.8% of tests (6.8x the national rate for this defect)
4. A transmission shaft constant velocity joint boot missing or no longer prevents the ingress of dirt etc, 8.5% of tests (5.53x the national rate for this defect)
5. Significant brake effort recorded with no brake applied indicating a binding brake, 4.5% of tests (4.3x the national rate for this defect)
6. Exhaust system leaking or insecure, 4.3% of tests (4.26x the national rate for this defect)
7. Brake pipe damaged or excessively corroded, 3.2% of tests (3.01x the national rate for this defect)
8. Stop lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning, 3.2% of tests (2.33x the national rate for this defect)

From 2,019 DVSA-tracked Rover 45 tests, 2024. DVSA testers marked 3.19% of these flagged Rover 45 defects as "dangerous", meaning the tester judged the car unsafe to drive away, against 5.11% nationally.

Most common MOT advisories on a Rover 45

An advisory doesn't fail the car - the tester flags it as worth watching, but it still passes. A different list from the failures above: what testers are noting on a Rover 45 before it actually fails on it.

1. The strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired, 21% of tests (13.8x the national rate for this advisory), also fails
2. Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced, 10.4% of tests (8.36x the national rate for this advisory), also fails
3. Significant brake effort recorded with no brake applied indicating a binding brake, 8.8% of tests (4.39x the national rate for this advisory), also fails
4. Exhaust system leaking or insecure, 9.1% of tests (3.19x the national rate for this advisory), also fails
5. Brake pipe damaged or excessively corroded, 19.5% of tests (3.15x the national rate for this advisory), also fails
6. Number plate inscription missing or illegible, 8.1% of tests (3.06x the national rate for this advisory)
7. A brake hose ferrule excessively corroded, 3.7% of tests (2.88x the national rate for this advisory)
8. A spring or spring component fractured or seriously weakened, 11.7% of tests (2.47x the national rate for this advisory)
9. Fluid leaking excessively and likely to harm the environment or to pose a safety risk to other road users, 13.4% of tests (2.4x the national rate for this advisory)
10. A suspension pin, bush or joint excessively worn, 28.4% of tests (2.12x the national rate for this advisory)
