Consumer Description

My vehicle has an oil consumption problem despite the fact that my car has been excluded from the class action lawsuit. I’ve had it in the shop and they have confirmed the oil consumption issues. There are countless other vehicles excluded from the class action lawsuit that have the same theta engine as the other vehicles that were included in the lawsuit. This needs to be investigated. I still owe over 6k on my car and it’s one trip away from being completely undriveable
