Based on 357 MOT tests from 15 vehicles analysed by VehicleScore®. The figures below describe that VehicleScore® sample. Recurring issues seen in VehicleScore® MOT data are not a claim that every LEXUS RX300 has the same fault.
LEXUS RX300's have a slightly over average reliability rating of 526/999. The score was calculated from the average of every LEXUS RX300 that has had a registered MOT.
We calculated all of the below figures by getting the score from each vehicle make/model/year/fuel, which are each calculated a score. We then generate the average score, taking into account factors such as mileage and emissions.

Recurring issues seen in VehicleScore® MOT data are inspection findings from this sample. They are not a statement that every LEXUS RX300 has the same fault. The median VehicleScore® in this sample is 486 out of 999.
These groups combine equivalent MOT comments, such as the same tyre note on different corners. Counts are comment occurrences in the sample, not a percentage of cars.
VehicleScore® MOT data includes 34 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.
These MOT comments record a worn, corroded, or damaged suspension arm or its pin.
What to inspect
Look for play or corrosion at the arm and ask whether it has been replaced.
Example MOT wording: NEARSIDE FRONT SUSPENSION ARM PIN OR BUSH WORN BUT NOT RESULTING IN EXCESSIVE MOVEMENT (5.3.4 (A) (I))
VehicleScore® MOT data includes 21 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 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: OFFSIDE FRONT TYRE WORN CLOSE TO LEGAL LIMIT/WORN ON EDGE (5.2.3 (E))
VehicleScore® MOT data includes 20 advisory comments and 2 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
Ask for recent pad replacement and look at the remaining pad thickness.
Example MOT wording: REAR BRAKE PAD(S) WEARING THIN (3.5.1G)
VehicleScore® MOT data includes 15 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.
These MOT comments record an oil leak noted by the tester. Shock absorber misting is counted as a damper issue, not as an engine oil leak.
What to inspect
Look under the engine for fresh oil, and check the oil level.
Example MOT wording: OIL LEAK, BUT NOT EXCESSIVE (8.4.1 (A) (I))
VehicleScore® MOT data includes 12 advisory comments and 2 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 a number plate that was deteriorated, insecure, or did not meet the plate rules.
What to inspect
Check both plates are secure, clean, and clearly readable.
Example MOT wording: FRONT REGISTRATION PLATE DETERIORATED BUT NOT LIKELY TO BE MISREAD (0.1 (B))
VehicleScore® MOT data includes 13 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.
These MOT comments record brake discs that were worn, scored, pitted, or corroded.
What to inspect
Look at the disc faces for deep scoring, a lip at the edge, and corrosion.
Example MOT wording: FRONT BRAKE DISC WORN, PITTED OR SCORED, BUT NOT SERIOUSLY WEAKENED (1.1.14 (A) (II))
VehicleScore® MOT data includes 12 failure comments in this group. Seen mainly as a failure reason. These are comment occurrences, not a share of all cars.
These MOT comments record a parking brake that did not hold well enough or had a component defect.
What to inspect
Test that the parking brake holds the car on a slope and releases cleanly.
Example MOT wording: PARKING BRAKE EFFICIENCY BELOW REQUIREMENTS (1.4.2 (A) (I))
VehicleScore® MOT data includes 7 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.
These MOT comments record corrosion the tester could see on the body or structure. Corrosion already named on a spring, brake, or other component is counted with that component.
What to inspect
Inspect the underside, sills, and subframe for heavy corrosion, especially where an advisory mentions it.
Example MOT wording: REAR SUB-FRAME CORRODED BUT NOT SERIOUSLY WEAKENED (5.3.3 (B) (I))
A model year is only commented on when VehicleScore® has at least 5 vehicles from that year.
| Year | Vehicles | MOT tests | Pass rate | Recurring issues seen |
|---|---|---|---|---|
| 2005 | 6 | 145 | 77.9% | Suspension arm issues, Tyre wear |
| 2004 | 5 | 117 | 78.6% | Suspension arm issues, Brake disc wear |
This is an inspection checklist based on MOT comments in the VehicleScore® sample. It does not mean the car you are looking at has these defects.
Suspension arm issues. Look for play or corrosion at the arm and ask whether it has been replaced.
Tyre wear. Check the tread depth and look for uneven wear, cracking, or damage on all four tyres.
Brake pad wear. Ask for recent pad replacement and look at the remaining pad thickness.
Oil leak. Look under the engine for fresh oil, and check the oil level.
Registration plate condition. Check both plates are secure, clean, and clearly readable.
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.
Corrosion. Inspect the underside, sills, and subframe for heavy corrosion, especially where an advisory mentions it.
Common problems tell you what can affect LEXUS RX300s generally. VehicleScore® can check the history of the actual car you're considering.
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.
