TURBO TROUBLES

I bought a new Mazda CX-5 2.2-litre diesel in June 2014. After 33,000km and three years the engine was replaced by Mazda under warranty. Nobody would explain to me what had happened to cause it to blow up. Now at 68,000km the turbo has malfunctioned. A replacement from Mazda is approximately $7000 and we’ll have to pay. What are your thoughts? I’d expect a turbo to last a lot longer? Greg Fox, email

A number of CX-5 diesel owners have reported turbo failure. The model was recalled in October 2019 for “an issue with accumulation of carbon deposits in the engine’s intake shutter valve” that may cause “premature wear of some engine parts”. Did you receive a recall notice and have the work done? Regardless, a turbo should last longer than eight years and 68,000km. If your services were carried out on time, speak to Mazda Australia and ask for a goodwill repair. If no joy, you can discuss options with the ACCC if you deem the turbo wasn’t fit for purpose. If you have no choice but to repair it, a Mazda specialist should be able to reduce that $7000 quote.
