Vehicle failed oil consumption test. Vehicle has been leaking and/or losing oil for months despite the issue being alleged fixed under the federal safety agency recall 18V272. The issue is ongoing and Mercedes Jacksonville is claiming the oil leak is from another issue not covered under warranty or recall order. I do not believe they are unrelated and they have not been able to identify the exact issue.
