Impossible to know the actual failure rate. (Sometimes there are multiple failures which indicates a defect in the surface of the block to me at least.) Only Toyota does and they aren't talking. I doubt a poll would really give the true #S.

Its not the typical old fashioned failure of cars past however. Yaris's just leak. Old cars the simple bearing failed and unless tended to immediately, total coolant loss resulted in a short time. Ive never heard of this with the Yaris.

It might be interesting to just torque the bolts of the wp and see what happens. Also, you might just keep adding coolant...the leak is very slow. Unless the bearing goes and the pulley wobbles I doubt total failure will happen. Periodic r and r of the drive belt and checking the pump pulley for play might be done.

I had my oil pressure sensor fail out of warranty. Like $150 at the dealer. I called Toyota Customer Service and after a time they reimbursed me so I only paid $40. I suspect I myself was the cause as I overfilled the sump once and I believe the car came from the factory with four quarts of oil if memory serves. Perhaps if people have wp failures out of warranty they might try this ploy.

In any event Im afraid this is a burden that must be born. The car is totally reliable otherwise and capable of hundreds of thousands of miles of service, more than any other.

It IS annoying however and you would think Toyota would consider its reputation and DO something about it like write us a letter here at Yaris world explaining the rate of failure and what measures they are taking.

Failing that we could all get together at selected dealerships around the country and explain the problem to management. Then we could all lay on the ground in the driveway so cars cant get in and out until they do something about it.
