What to check before buying a 2013 Is 300H Cvt
Before buying a 2013 Lexus Is 300H Cvt, focus on the areas it most often fails on. Lighting & signalling accounted for 4.8% of tests for this year.
- Lighting & signalling (4.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (4.7% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Brakes (2.9% 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.
