2015: “While the vehicle is turned on but stationary (e.g. Stopped at a red light in light traffic) I began to smell diesel exhaust in the cabin of the vehicle. The odor was very strong and I had to lower the windows in order to breathe. The mechanic informed me that there was an oil leak near the turbo. I had to replace the fuel injector and leak line, in addition to all pipe seals at turbo.”

It is june 26 and the parts are still not available. Waiting for almost 12 months to have the airbag recall replacement parts. This is a serious safety hazard to wait almost a year to be repaired.”
