It hasn’t been a good year for diesel. There’s the whole VW mess, a BlueTEC Mercedes-Benz lawsuit in California, and a GM Duramax lawsuit in Michigan. And now Mazda is issuing a recall for diesel engines outside the USA that stall, leak fuel, and catch on fire. Well, at least it’s not emissions-related? Here are a few of the issues:
“Mazda says the fastening force of the injector mounting nut is faulty and can cause too much pressure on the injector gasket. If this condition occurs, the fuel blows through the cylinder head causing the engine oil to become carbonized and clog the oil strainer.”
And then there’s:
“The sealing performance of the fuel return hose can deteriorate and lead to cracks inside the hose, causing fuel to leak from the hose.”
Oh yeah, then there’s:
“The diesel engines can also stall because pressure in the cylinders and the closing force of the intake valves can decrease, catching soot between the intake valves and the valve seats. If this occurs, the engine will have poor compression and unstable rotation, causing the engine to stall.”
As of right now, the recall doesn’t affect US diesels but that could change. You can get the full rundown on CarComplaints.com.
