“The vvti hose (engine oil cooler pipe) on my Lexus ruptured while I was driving which then caused a massive oil leak in just a couple of minutes. This was a faulty design by toyota, rubber part was used instead of all one piece metal part. This should have been a recall. My total cost of repair is $367 u.s. Dollars and I am filing a complaint with toyota to get my money back.”
