My 2012 prius c car hybrid battery also went kaput last week. three days repair and back online already. Still under warranty though, if not the hybrid battery costs RM6700+RM300 labour. And I service outside Toyota so I got a warning to service the car in Toyota next time. However I am not the only one who got away with not servicing by toyota. You can google and can find one blog.

The small battery (every car has this) is also weak. However I got no budget and defer the replacement. Mind you the car is 5 years old and never replace the small battery. the small battery costs RM1100 though.

The car is really cheap maintainance. Never change brake pad (and they are still thick). No timing belt. No brake fluid change.

Try Toyota Subang.
