What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2011 Audi A4, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
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
Engine oil consumption, timing chain. This is a massive problem among Audi vehicles across the board. Engine oil consumption is abnormal and if unnoticed leads to engine dying in the middle of the road which is dangerous and I’ve personally had this happen to me on multiple occasions. The engines timing chain goes bad and causes the entire engine to need to be replaced which consumers have to pay for out of pocket. Damage from timing chain, rough idle, sluggish engine performance, rattling, engine failure. There are large amounts of consumers experiencing the exact same issues. Something needs to be done it’s not safe at all and Audi should be held responsible and liable to fix these issues. The engines are deteriorating at an abnormal and accelerated rate.
So there have already been recalls on some audis for oil consumption. I have a 2011 Audi A4 quattro and it goes through oil like crazy. It's ridiculous I believe it's because of faulty piston rings which led to faulty head gasket witch leads to the spark plugs, and coils.

From owner reports, verbatim
Vehicle has horrible oil consumption due to piston rings being defective upon manufacture.

Seat belts
Reports naming seat belts, buckles, retractors and pretensioners.
From owner reports, verbatim
As of yesterday 10/18/2023, the drivers seat belt would not connect, I forced it to connect, but the dash light indicator remains on. also, difficult to release. I'm concerned that in an accident the air bags won't deploy and worse I may be trapped in the vehicle. My mechanic told me that there were recalls on these Audi's, however I can't find any and the dealer said there is no recall and that they would charge me $200 dollars just to inspect it.
