Okay I have now owned my YRV turbo for close on 5 years (time flies and all that).
I thought it be best to put a list of things I have had to had replaced which may help other owners.

These are known for the YRV Turbo and should be looked at:

1).. Anti roll bar and backets which are prone to snap. Brackets were updated by Daihatsu but not all cars were done. Dee warranty at the time

2).. Water pump. My water pump was replaced last year, and lucky it was as it was starting to leak. Another one of those parts that don't last.

3).. Sills. Another Achilles heal on the YRv and possibly sirion. Check them especially if you have side skirts like most YRV and sirion models have as these can rot. Mine had started at the rear and fronts, and had to get welded to pass an MOT.

4).. Original y shaped exhaust. Some cars had them replaced under warranty due to rot. Again not all cars got the updated ones.

5).. The fuel pipe. This is a new one that I am now experiencing. They rust like mad. Now looking at gett g a new one fitted due to excessive rust and the likely failure. Again this needs checking by owners on both YRV and Sirion.

6).. O2/Lambda sensors. All cars have these and out of precaution I got mine changed. But there are reports of owners with cars not even hitting 100K miles of getting ECU lights coming on due to failing O2 sensors.

7).. Rear offside inner wheel bearing failure. Got both of mine changed on the last service. The inner offside bearing was FUBARRED. But as the car is light, you would never know it. Both sides and bearings swapped with new ones.

Hopefully this information may come in useful to owners.
