What to check before buying a 2005 Rx400 H -L Cvt
Before buying a 2005 Lexus Rx400 H -L Cvt, focus on the areas it most often fails on. Lighting & signalling accounted for 9.5% of tests for this year.
- Lighting & signalling (9.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (8.5% 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 (6.4% 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.
