Toyota Yaris reliability

one dude has over 400,000 miles on his 07 yaris on the original water pump.

I don't believe it either. Sure it's possible, but I'm certain this isn't a common issue by any means but rather a rarity. There are a number of high mileage Yaris's that have reported no issues. Mine is at 85,000 miles and shows no sign of wear and is repair free.

I know is hard to believe that such simple part like a water pump will fail so soon, I almost don’t believe it either when this happened to my yaris, most of the cars know days can do more than 120K w/o replacing the water pump but on 1nz-fe its common, even the prius has the same problem, I was told by the mechanic at the Toyota dealer that they replace them all the time.
The yaris is not the first car I owned and surprisingly it’s been the one with more defects. When I traded my 350z for the yaris I did it for gas economy and good quality, the Z was amazing in quality but I needed a 4 seater.

Here are few pictures that show my WP leak and know my GB

I had that same pink crust on my WP, and the typical pink marking on the underside of the hood. I believe it had only leaked for a short amount of time and stopped somehow, as it was just all crust, not wet at all, but I went ahead and replaced it anyway. I also changed out the long life coolant to regular stuff. I hope I did the right thing there, as the long life coolant seems to be the problem for these water pumps...

What is the general cost of replacing the water pump on a Yaris at a dealer or typical shop (with labor)?

I think its pretty premature to come to that conclusion. The coolant you mention doesnt appear to be affecting the wp s of other cars.

[goliath1812]

If that's the case, then great. But from what I have read on here with the W/P problems, that was the main thing that seemed to be the problem. This is all second have from what I have read.

The coolant may be a good reason for the WP to go faster, probably Toyota pink coolant doesn’t lubricate the pump the way it should, if that’s not the case the 1NZ-FE water pump is made with cheap materials and wear fast...

Its a mysterey to me why this happens. ECHOs had the same water pump/coolant and I NEVER saw a post about the wp going.

Just turned over to 5,000 miles on my way to work this morning... almost six months old! Only a routine oil change so far...

*NO PROBLEMS*

Cheers!

I'm hitting 60k miles never had a problem regular synthetic oil changes, used only premium 93 gas only since day 1. Have the NST pulley set as well on the water pump, might have to replace it soon since a nice groove is showing up on my pulley.

"premium" (as in price) gas in a Yaris? Why on Earth?

You're just wasting money on 93. The Yaris is tuned for regular 87. Running higher may actually have a similar adverse affect as running regular in a premium car.

51,500k miles/2.5yrs and going strong. Still just one repair on an axle seal @ 13k miles. Running 10k synthetic oil intervals with 5k filter intervals. Stock everything, only mods are tints, subs, and scanguage. Should be close to 60,000 miles by september. My car is about to become a work tool, so i'll probably jump from doing 20k a year to 25-30k a year.

OTOWNYARIS....If you have not seen my post about the TSB EG048-07 you might consider looking at it. This TSB outline the replacement of the defective fuel tank
fillerneck cover....if the failure occurs outside your warranty period the canist/filter parts
cost is near $1000 from your pocket..... Check your VIN # and see if it applies to you...
it happened to me the FIRST time I took a 2 hour drive in a constant rain...

We have updated results for the Yaris to include owner experiences through March 31, 2010. In terms of repair trips per 100 cars per year:

2009: 20 participants, no repairs reported yet

2008: 7

2007: 20

All are very low, and much better than average.

We have two additional statistics, "Nada-odds" and "Lemon-odds," to indicate the percentage of cars with no repairs in the past year and those that required 3+ trips to the repair shop.

In the case of the Yaris, the percentage with no repairs is about 87 for the 2007 and 92 for the 2008, and the percentage of lemons is less than one for both years.

A big thank you, once again, to everyone who has been helping. We'll have further updates in August and November. With more participants, we could provide more precise information and provide all three stats for all model years. Especially need more 2009s and 2010s.

Updated stats in a couple of weeks.

Sample sizes are small for the 2009 and up--especially need more participants for these years.

I just saw Advanced Auto is now selling a house brand fully synthetic for 3.49 a quart! Dont know anything about it yet, but sure is tempting......
I'd do a flush too myself, but thats just me. Factory stuff is good, but I think a mild flush couldnt hurt. And as far as that goes, when you drain it, take a look down in the radiator. I know its not absolute, but if you see scale or other build up there, its in other areas too.

We have updated results for the Yaris to include owner experiences through June 30, 2010. Other sources of car reliability information won't cover the more recent months until the summer or even fall of next year. Repair frequencies, in terms of repair trips per 100 cars per year:

2010: no repairs reported yet, 14 participants

2009: 7

2008: 7

2007: 15

All are very low, and much better than average.
