I noticed what looked like a water leak on the floor of my driver side mat. Took it Toyota and it is fact a leaking master cylinder, and that also includes the traction control. I have extra care on my Prado so it will all be covered under that warranty. I have inquired around with different diesel fitters and was told it is not a common problem but it does happen.......About 3-5% of 150's out of Japan will have the problem......
