LEXUS CT200h 2012 160,000 Miles- Where to service

Lexus Relax warranty is limited to 185,000km so no point going to Lexus for a service.

OP, its a 1.5 Toyota engine, just go to any independent mechanic. The hybrid battery does not require any service or checks. Just change the oil every 15,000km and continue driving.

1.8 Toyota engine then. It doesn’t require a specialist. Any mechanic can service them.

Whats this 185k km limit then?

That's an incredible level of confidence to give a 1M km warranty.
