The documented failure patterns on used Toyota Priuss — the mileage window where each shows up,
and what the repair typically costs at an independent shop. This is the same data NoLemon's Brief checks
against every VIN.

2006–2009TYPICAL 40k–160k MI$150–$800
HID headlights shut off intermittently
Factory HID low beams flicker or cut out at random — sometimes both at once; a class action covered it years ago. Run both headlights during the test drive and ask whether bulbs or ballasts were replaced. A bulb runs about $150; a failed ballast pushes the bill toward $800.
BEFORE YOU BUY Ask for repair records covering this item. If it hasn't been addressed and the
car is in or near the mileage window, price the $150–$800 repair into your offer — or make it the seller's problem.
2010–2015TYPICAL 80k–180k MI$2,000–$4,000
Brake booster pump / actuator failure
The brake booster pump assembly fails, lighting the ABS and brake warnings and changing how the pedal feels; codes like C1391 confirm it. Toyota extended the warranty on the assembly, but it has lapsed for most cars and the repair runs $2,500–4,000. Any brake warning light on a test drive is a walk-away or a big discount.

2010–2015TYPICAL 120k–220k MI$1,500–$4,000
Oil burning & head gasket failure
High-mileage third-gen engines burn oil through worn piston rings and then blow head gaskets, usually announced by a shudder or misfire on the first cold start of the day. Check the dipstick and insist on hearing a stone-cold start. A gasket job runs $1,500–2,500 at an independent shop; a replacement engine costs more.
