2007 Lexus Rx400 H — MOT failures & pass rate
The 2007 Lexus Rx400 H passed 81.6% of its 843 recorded MOT tests. All cars of a similar age fail 26.9% of the time, so this is 8.5pp better than the group it competes with. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
Lighting & signalling dominates the failure mix at 12.2% of all tests — 3.8 points clear of brakes, so it is the first thing to check.
At component level the recurring items are position lamp, headlamp aim and rbt (sp) — position lamp alone was recorded 57 times.
Mileage matters less than usual here: the 2007 Rx400 H fails 19.3% of the time in the 60-90k band and 21.5% at 150k+, a spread of only 2.2 points.
Advisories point at the next bill rather than this one: suspension was flagged on 43.2% of tests without failing them.
The trend is worsening — 15.5% of tests failed in 2021 against 18.4% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2007 Rx400 H
On a 2007 Rx400 H, lighting & signalling is what the MOT record says goes wrong most — it appeared in 12.2% of tests. Check these areas before you commit.
- Lighting & signalling (12.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (8.4% 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.
- Suspension (6.8% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
