Poll: Replace Engine & HV or Part out (2010 IV)

Those codes are weird; is somebody leaving off the first two characters? What was used to read them?

There are various reasons an engine can be misfiring. It can sound like the hammers of doom if it's misfiring badly, then purr like a kitten if the problem is fixed, which sometimes is something easy.

But letting the misfires go on too long increases the chances of mechanical damage from all the banging, or catalytic converter damage from receiving unburned fuel.

 

You need a new car. Push the Prius to the back of the driveway, it has so little value now that how you dispose of it has no effect on your future transportation needs. Interest rates are low, time to move on.

 

Since actual daily mileage driving and money saved to buy another car wasn’t disclosed, sell it as is & get a prius prime.

 

buy something that no one wants right now for cheap money. don't worry about gas prices for the foreseeable future

 

Not knowing how thoroughly you and your mechanic have inspected things so far, beyond the codes, but ...

The last 4 codes listed are all "just" misfires. In most cars, a true misfire in one cylinder may show up as codes on several others as well.

The fuel injector code could be a true problem, which may well be causing all 4 misfire codes, at least.

Could it be that the mechanic's diagnosis was hasty and based simply on misfires and the notoriety of these cars for HG issues as they approach 200k miles?

170k miles is pretty new still. I would look into that fuel injector #3 circuit malfunction at least. Maybe you've got a loose wire. I mean, at least before you crush the car ...

Of course a hybrid battery on its way out is completely unrelated.

 

For anyone similarly challenged: I think the "HV" in the title means "Hybrid Battery".

@ms.chevious : to help responders, where are you? In the States?

 

I saw some where that HV means Hybrid Vehicle. I can't remember where I saw it, but did see it several times.
I guess it would depend on what they were talking about, and whom...

 

I have an early 2010, and NO problems. I use about 1 quart per 10,000 miles oil changes.
Unlessssss...... I'm driving 70mph and driving faster around town. 85% of my driving is highway.
I have 199,931 miles on it. I got it at 116,xxx.

I would say it depends on HOW you are driving it and if you do the schedules maintenance on time.
And cleaning the egr circuit, which is not normal maintenance. I last cleaned mine at 139,000.
I don't think the previous owner cleaned it. They drove most highway miles also.

2015 would be the "best" bet for the 3rd generation. It would have the latest updates. And they did change
the pistons and rings.
