What to check before buying a 2020 Niro 2 Phev S-A
Before buying a 2020 Kia Niro 2 Phev S-A, focus on the areas it most often fails on. Lighting & signalling accounted for 3.9% of tests for this year.
- Lighting & signalling (3.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (3.6% 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.
- Visibility (1.9% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
