We have had a white, 2012 IQ3 1.33 auto from new. It has only done 21k miles and has been trouble free. But the paint started to peel off the roof. Our local dealer (Toyota Bristol South) referred it to Toyota in October 17. It was eventually sanctioned and went in early January. We were provided with a Yaris hybrid for over three weeks (my daughter loved that so much she bought a new one) and it has come back looking like a new car, with new outside trim and badges (they left the old stuff in the car).
So Toyota honoured their warranty / commitment to this customer, and got an order for a new Yaris soon after. Is it any surprise they are one of the biggest car makers in the world?
The Yaris was as quite as a lamb to drive and averaged 60 mpg over the time with us - not bad eh.
