Are there three major fixes for a 2007 Prius?

By fixes do you preventative? Or do you mean fixes in terms of the three most expensive repairs?

 

Failures that will eventually happen to a Gen2 car.

1. Combination meter (minor)
2. ABS actuator (major)
3. Hybrid Battery (major)
4. Inverter pump (minor)
5. Get catalytic converter stolen (major in CA, minor in other states)

All the rest of the car will have failures like any other car as it ages.

 

That about covers it...

For preventative:

1) Replace Wire Frame #2 on Hybrid Battry pack before corrosion damages Battery ECU where it plugs in (high humidity regions)

2) Regularly charge, balance and recondition hybrid battery to maintain capacity (every 18 months)

3) Steal and sell your own expensive catlytic converter before someone else does & replace w/cheap aftermarket one. Also install cat shield to help deter theft.

4) Regularly check oil level and top off between oil changes once you're above 100K miles

5) Replace Trans fluid at least once

 

The nice people here will try to be helpful with answers to this.

But they will be mostly worthless unless you tell us what two things you already know.
Or think you know.

The things you already know need to be done might not even be on the mythical "list of 3".
Who was it that told you that in the first place ?

 

Will try adding another mostly "worthless" answer;

6. AC system (major)

 

That's too funny because most of these things I've bought I've just vacuumed them down and charged them up carefully and they work like a charm it's funny

Inverters are not a problem in Gen2... Gen3 Inverters have a recall for some years.

 

The inverter is not a common failure on the gen2 cars. A new part will run into the thousands of dollars. However since these parts rarely fail, junk yards are full of these parts (if you ever need it). The inverter pump, that's the more common failure on the gen2 cars. That will need replacement around every 100k miles

 

No need to fix (or replace) the inverter, unless you plan on driving around with a failed "inverter coolant pump", and in turn blow it up.

Are you trying to throw parts at this vehicle, or do you have some known OBD2 codes (DTCs) that point to these "three major fixes" ?

 

Everyone who reads a forum like this needs to understand that places like this tend to MAGNIFY any common reoccurring problem, no matter how small and infrequent it might be.

Virtually NOBODY comes to a forum like this just to say "I have a 2005 model with 150,000 miles on it and it has been the perfect car." But a lot of people come to report or ask for help on problems that may not really be that common.

 

Inverter costs.

Part of the inverter assembly is a DC to DC converter to make 201 volts into 12 volts. (Actually a little higher, so it charges the 12 volt battery)

While reliable, it fails if you reverse jumper cables. The dealer will replace the entire unit but you can get the Air Conditioning and DC to DC board for much less. My take away is don't use jumper cables, use a jump pack.

From 15:05 to 18:05 he is talking about that board. The entire video is first rate.

 

it will work like any car. if you have a major failure or something goes wrong then there are costs associated to fix them

 

I have 4 or 5 inverters here . brake actuators too. Other parts too I pick em up as I see them stack up at the yards . Same as I did for my rollas.

Gen 2 engines are very happy with 5000 mile oil changes, transaxle wants drain and fill with ATF WS every 100,000 miles.

 

Very happy with 5,000 mi oil changes no once I get up around 300K I'm going right to 10,000 mi oil changes if not closer to 15 just because it's not going to make any wear come on any quicker at that point . Sooo.. I'm looking this car maybe to go the 5 or 600 K

They are reliable! Keep up with checking your oil regularly and changes every 5k miles and keep all fluids full and changed at the proper intervals and you should be good
