The Story Behind This Site
I bought my 2007 Toyota Prius new off the lot. Seventeen years later, I handed over the keys — but not before this car taught me more about hybrid systems, DIY repair, and the value of community knowledge than anything else in my life.
Over those years, I watched forums go dark, image hosts die, and YouTube guides disappear. The knowledge scattered across a thousand threads on PriusChat, Reddit, and defunct blogs — hard to find, impossible to save.
This site is my attempt to fix that. Everything I learned — repair timelines, part numbers, Florida heat quirks, junkyard tips, what's worth fixing and what isn't — preserved in one place, free forever, and open for anyone to improve.
If you still own a Gen 2 Prius, this site is for you. Fork it. Add your own knowledge. Help keep these cars on the road.

Most Common Repairs
Hybrid Battery
Red triangle on dash. Loss of power. The big one. How to test, recondition, or replace your Gen 2 hybrid pack.
HardInverter Coolant Pump
This tiny $80 pump keeps your inverter alive. It fails silently. One of the best preventive repairs you can do — before it destroys the inverter.
EasyP0420 — Catalytic Converter
The most common check engine light on high-mileage Gen 2 Priuses. Usually not an emergency. Covers diagnosis, cat vs. O2 sensor, and theft.
Medium12V Auxiliary Battery
When this dies, the car is completely dead — no dash, no locks, nothing. Replace every 3–5 years. Easy DIY most owners ignore until they're stranded.
EasyABS Actuator
Three warning lights at once: ABS, VSC, and brake. The actuator pump runs constantly and drains the battery. Dealer wants $1,500. There's a better way.
HardCombination Meter
Speedometer drops to 0 while driving. Fuel gauge stuck. Odometer frozen. A capacitor repair can save $400+ over dealer replacement.
MediumMFD Screen Goes Dark
Touchscreen goes completely black but the car drives fine. Try the DOME fuse first — it's free and takes 5 minutes. Full replacement guide if that doesn't work.
EasyOil Consumption
At 150k+ miles the engine starts burning oil between changes. Knocking and weak acceleration are the symptoms — but by then it's already dangerously low.
EasyAC Stops Blowing Cold
After 10+ years in a hot climate, the AC loses refrigerant. A $20 R-134a can from Walmart buys more time. Covers the correct procedure and what diminishing results tell you.
