Why has the turbo in my Mazda 3 seized?
I have a 2013 Mazda 3 Venture 1.6d which has done 42,000 miles. I have owned it from new and had it serviced annually at a Mazda main dealer. Last week it lost power and the engine warning light came on. The garage has advised it is a seized turbo. Is this a known fault? Given the cars age, mileage and service history should I expect Mazda to pay for or contribute to the cost of the repair?
It's not a Mazda engine, it's a Ford engine, and the turbos seize because the engine has been switched off too often when the turbo was red hot. This carbonises the oil in the turbo bearing and the turbo oil feed and oil return pipes and will be why your turbo failed.
