Tyre wear

VehicleScore MOT data includes 119 advisory comments and 23 failure comments in this group. Seen as both an advisory and a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record tyres that were worn, damaged, or close to the legal tread depth when the car was inspected.

What to inspect

Check the tread depth and look for uneven wear, cracking, or damage on all four tyres.

Example MOT wording: NEARSIDE FRONT TYRE WORN CLOSE TO LEGAL LIMIT/WORN ON EDGE (5.2.3 (E))

Brake pad wear

VehicleScore MOT data includes 19 advisory comments and 3 failure comments in this group. Seen as both an advisory and a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record brake pads that were worn or below the inspection limit.

What to inspect

Example MOT wording: FRONT BRAKE PAD(S) WEARING THIN (1.1.13 (A) (II))

Brake disc wear

VehicleScore MOT data includes 17 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.

Brake disc wear. Look at the disc faces for deep scoring, a lip at the edge, and corrosion.
Parking brake faults. Test that the parking brake holds the car on a slope and releases cleanly.
Oil leak. Look under the engine for fresh oil, and check the oil level.
Windscreen damage. Look for chips and cracks, especially in the area swept by the wipers.

Buying a JEEP GRAND CHEROKEE?

Common problems tell you what can affect JEEP GRAND CHEROKEEs generally. VehicleScore can check the history of the actual car you're considering.

Where does this data come from?

VehicleScore analyses MOT histories from vehicles in its own dataset. Sample sizes vary by model, and a small sample is labelled as such. MOT data records roadworthiness and inspection defects. It does not capture every mechanical or electronic problem a car can have, and a comment on one test is not proof that the model has an inherent fault.
