2012 Audi A4 Problems

Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

I HAVE GONE GONE TO THE DEALER NUMEROUS TIMES VISITS RIGHT AFTER I HAD THE SCHEDULED OIL CHANGES DONE. THE OIL LIGHT / CONSUMPTION ISSUE HAPPENS AFTER I'VE GOTTEN AN OIL CHANGE, BUT 7,000 MILES BEFORE THE NEXT ONE IS DUE. I GET AFRAID THINKING THAT MY CAR IS OUT OF OIL . I DO NOT HAVE ANY OIL LEAKS. OIL IS LEAKING AROUND LADDER FRAME. THIS HAS BEEN A KNOW ISSUE FOR A FEW YEARS THAT I HAVE BEEN HAVING AND AUDI WILL NOT RESOLVE.
