Another triangle of sadness, please help me?

it could be a combination of many issues. But my guess would be hv battery failure and/or inverter cooling pump failure. If you haven't changed the oil in a while, the engine might also be starved of oil

Has nothing to do with the gas cap and 12v battery

 

Your 3 way coolant valve is not causing those lights, I mentioned it could be a combination of you HV battery failing and/or inverter pump failing.

Your 2008 is out of warranty for emissions related parts and also out of warranty for hybrid battery. emissions warranty is 15 years/150k miles. hv battery warranty is 10 years/150k miles.

 

If you are getting 35 mpg the hybrid battery is a suspect.



Codes will tell the story. Being in LA you should take it to an independent for a quick diagnosis, perhaps Hybrid Pit.

 

You should always check the codes to make sure of the problem before you do any repairs. What I replied with is just my experience from the symptoms you're experiencing.

If you are in need of a hybrid battery, of course a new oem battery would be best. The cost for something like that is $2500 installed and will give you 10+ years of reliable service. There are cheaper options for "rebuilt" batteries. But the rebuilding quality can vary greatly and can potentially give you lots of headaches when the battery fails again.

As for the inverter pump, the price a professional will charge is $500+. If you buy the part and do it yourself, an OEM part will be around $120.

Both of these items are fairly easy to do on your own. Lots of information on this site to help guilde you with the repair.

 

The shop I recommend would be the one I'm always at, a shop in Rosemead CA, Armstrong Auto Services. Everyone there drives a Prius so we've seen and repaired almost every issue with the car.

 

That is a bit off the mark for the battery. Price is usually in the range of $1650-$2000. Labor is usually $400-$600.

Buy only a new battery; there are very few new aftermarket options so be very careful looking at aftermarket.

Do not buy any reconditioned/remanufactured/rebuilt batteries unless you would be happy with 6 months to two years life out of those solutions.

The inverter pump price is good if they are using a new OEM pump. Aftermarket pumps can be cheaper but the statistics on reliability do not go in their favour.

 

^^^ This.

Always makes me sad to see a thread go on this long, with talk of hundreds of dollars for parts, and no trouble codes looked at yet.

 

Enter your age in your profile stats? It's always good to know; you get a sense of the mindset.

 

Human nature. Most people understand "replacing parts". Very few want to learn how something works in order to test it properly.

Try to educate those will listen. Otherwise grab a box of tissues, dry those teary eyes, and move on.

The inverter pump is a 30 minute job for the monkeys and the Amoco transmission commercial from the '70s very straightforward My recommendation would be removed the pump from the bracket leave the bracket in the car squeeze the hoses closed stick a cork in them whatever leave most of your coolant in the system change out the pump reattach the hoses Don't forget the electrical connector and no you don't have to remove the headlight unless you just like to do those sort of things You need a 10 mm short socket two 6-in extensions a pair of vent needle nose which are very inexpensive at any store you'll need them later too and that should pretty much get you ripping so if all that is worth 300 plus dollars to you sounds good The pump now should be able to be had for about $120 130. So the rest is your time or money for the 45 minutes I'll take my time any day.

 

Hey, I said sad. I didn't say that sad.

 

I'm not sure which dealership will charge only $400. That is very low in the Los Angeles area. That is more the price of a small garage or a side job for a mechanic.

Hopefully that is all the codes point to, it just seems the warning lights might point to more than just that one issue, there are just too many warning lights on.

 

You have a combination meter problem, the speedometer has a capacitor that needs to be replaced. It's a common problem for this generation car.

 

Circuit board on dash top that has beeper on back of it needs capacitors replaced. Is very common and on YouTube . But car still drives and maybe check engine light works on boot of car I drive with no display all time on two cars.

 

When you're posting about an issue on PriusChat, you can always get the best informed responses if you include the actual code(s) in your post, not just what somebody said the code was "for". If you say it was P0A93, for example, we all know what that code is, or can look it up. If you just say it's "for the inverter pump", we don't really know what code you had, or what you found that said that code's "for the inverter pump", and we're kind of groping backwards in the dark.

As a first guess, was your code P0A93?

This is another example where it helps a lot more if you get us straight to your source of information. "Cheat codes" are gamer things, not Prius things. There are a number of specific procedures that are shown (in the repair manual, not random youtubes) for doing specific things, though I'm not familiar with any like the one you describe here. You can find lots of youtubes, though, that say lots of things. If you include a link to the one that you found, that gives us a way to see what it's talking about, or whether it's just bogus (a lot of them are).

As other posters have suggested, the dash problem sounds mostly like the bad capacitor issue. It's a known issue. It will behave pretty randomly for a while before it conks out completely. People prone to wishful thinking often try a bunch of random things while it's behaving randomly, which means some of those things will coincide with the dash lighting up again, and may then end up on youtube as "cheat codes".
