The Honda S660 is a lightweight two seater roadster sold mainly in Japan between 2015 and 2022. Built as a modern Kei sports car, it has a 660cc turbocharged engine and rear wheel drive. Many examples have been imported into the UK, where they appeal to enthusiasts looking for something rare, fun, and efficient. While generally reliable, the Honda S660 does have some known weaknesses. This guide explains the most common Honda S660 problems and typical UK repair costs.
About the Honda S660
The Honda S660 was designed as a spiritual successor to the Honda Beat. It offers:
- A 660cc turbocharged three cylinder engine
- Six speed manual or CVT gearbox
- Rear wheel drive handling in a compact body
- Lightweight construction for agility and efficiency
As a Kei car, the S660 meets strict Japanese regulations but requires careful maintenance when imported into the UK.
Common Honda S660 Problems
- Turbocharger wear
The small turbo works hard, and higher mileage cars may show reduced performance as the unit wears out. - Clutch wear
Manual models can suffer from clutch wear if driven aggressively. - CVT gearbox issues
CVT versions can develop judder or slipping if the transmission fluid is not replaced on schedule. - Suspension wear
Bushes and shocks often wear more quickly on UK roads, leading to knocks and rattles. - Electrical faults
Sensor errors and dashboard warning lights are reported, often needing resets or replacements. - Air conditioning problems
Older cars may suffer leaks or compressor failures that reduce cooling. - Rust
Imported cars can show underbody corrosion if not treated after arriving in the UK. - Parts availability
Since the S660 was never officially sold in the UK, parts often need to be ordered from Japan, which increases costs and waiting times.
