2019 Mercedes-Benz Hymer — MOT failures & pass rate
341 MOT tests on the 2019 Mercedes-Benz Hymer are in this dataset, and 91.5% of them passed. All cars of a similar age fail 10.2% of the time, so this is 1.7pp better than the group it competes with. Failures cluster in lighting & signalling, brakes and visibility.
What the MOT record shows
No single area dominates — lighting & signalling (5.6%) and brakes (3.8%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are brake discs, headlamp aim and wipers — brake discs alone was recorded 13 times.
Advisories point at the next bill rather than this one: brakes was flagged on 9.1% of tests without failing them.

What to check before buying a 2019 Hymer
On a 2019 Hymer, lighting & signalling is what the MOT record says goes wrong most — it appeared in 5.6% of tests. Check these areas before you commit.
- Lighting & signalling (5.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (3.8% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
- Visibility (2.9% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
