2004 Prius weird noises just purchased

Maybe you should have your uncle buy it......LOL

How many miles on the car? How much did you pay?

1. The odometer not turning on is your combination meter going bad, the warranty is only for 9 years, which you are out of warranty.
2. The sound from under the hood sounds like the actuator pump, defective/broken.
3. If the AC is leaking, it's already a bad sign. And even worse, you just added regular Freon to the car to contaminate the system.

I would suggest you get all the DTC codes read so you can figure out what's wrong with the car. Honestly, if you can return it, return it.

 

This is your ABS pump running. It is normal for it to run occasionally especially after applying the brakes. Yours is running way too much and you will need to replace it. This is quite expensive at the dealer. If you find a used pump and install it you can save some coin.

 

The combination meter had an extended warranty for 9 years and unlimited mileage but it would be over by now. Contact Steve at Prius hybrids sales and service Scottsburg Indiana to get that repaired cheap.

 

It is running because it is losing pressure. There is probably an internal leak in the accumulator. It will get worse and become unsafe unfortunately.

 

If being able to brake is important to you, then it would be a problem by letting the ABS pump run.

The 12v battery can cause many problems, replace that first and go from there.

 

It is also probably draining your 12v because it runs constantly. I believe it stops after a while if a door or hood is not opened.

 

good plan on the cells, but be prepared to do it every so often.

 

It will not need to be programmed but it will display the mileage of the donor car. You could also send your old one to Steve at Prius hybrids sales and service Scottsburg Indiana to have it repaired and your mileage would be correct. If you buy a used one it need to come from a 2004-05. Newer ones will work but you will have a TPMs tire light on that wont go away.
