What the known faults on this Toyota Prius typically cost to put right at a UK independent garage · use the figures to price risk before you bid, and to justify a reduction when something shows up on inspection.
The single priciest documented job on the 2010–2015 Toyota Prius is head gasket / cooling system repair at £900–£2,600. Few cars need every repair listed here · treat £3,150–£9,700 as the full exposure if one arrived with all of them.
Reduced hybrid battery performance, increased fan noise from the rear cabin, or overheating fault codes.
Inspect · Shine a torch into the hybrid battery cooling intake vent located on the side of the offside rear passenger seat to check for heavy dust, lint, or pet hair build-up.
