What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2012 Audi A4, grouped by the component NHTSA recorded on the report.

Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
There is a recall for the year after this when many Audi owners of this model have the same issue per the Audi forums. We have the coolant leaking issue as well and it should have been included in the recall
1) Turbo, not because I'm looking to replace it 2) the car could stall when merging into highway or passing on the left lane 3) Yes 4) No 5) Yes, Check Engine Light came on afterward Check engine light came on after I tried to merge into a lane, while I was stepping on the gas peddle hard there was no acceleration. While the car did not stall, but it was not moving fast enough to provide the distance I need to be safe from the car behind me.
Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
HAVING ACCELERATION PROBLEMS. VARIES NOT CONSISTENT. WHEN APPLYING PEDAL TO ACCELERATE. THE CAR DOESN'T RESPOND. RPM DROPS TO ZERO. ENGINE STILL RUNS BUT NO MOVEMENT. RELEASING PEDAL AND TRYING AGAIN WORKS INTERMITTENTLY. SCARY WHEN TRYING TO GET CAR OUT OF DANGER.
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.

This vehicles Water Pump has failed and has been replaced 3 times in the last 3 years. I fear for the safety of the vehicle. We've received numerous correspondence regarding class actions suits and such for cooling system issues.
AS I ACCELERATE FROM 0 TO AROUND 2K RPM, CAR JERKS RAPIDLY AND THEN CONTINUES TO FIX ITSELF TO BE SMOOTH. EVEN ON 55MPH SPEED AND I DECIDE TO PRESS THE ACCELERATOR DOWN QUITE A BIT, THE CAR JERKS AGAIN.
