What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2015 Audi A5, 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.

From owner reports, verbatim
After purchasing the vehicle on 8/2/25, I discovered it had outstanding safety recalls that were neither addressed nor disclosed by the dealership at the time of sale. I have since taken steps to fix these safety issues, but the dealer’s failure to inform me or resolve the recalls before the sale put me at unnecessary risk. I urge the NHTSA to review the dealership’s records from 8/2/25 to hold them accountable for selling a vehicle with unresolved safety defects that compromised my safety. It is not allowing me to add case card with report, only case card available as of today.
CHECK ENGINE LIGHT CAME ON WHILE VEHICLE WAS IN MOTION ON AN INTERSTATE HIGHWAY. IT LATER WENT OFF WHILE DRIVING ON CITY STREETS. DEALER ADVISED THAT FUEL HOSE NEEDED REPLACEMENT AT COST OF $1,198. DEALER STATED THERE WAS A FLAW IN THE ORIGINAL HOSE AND THAT A REPLACEMENT KIT MUST BE INSTALLED. DEALER ADVISED THAT THIS IS A DANGEROUS SITUATION AND I SHOULD NOT DRIVE MY CAR HOME. DEALER STATED THAT THIS IS NOT COVERED UNDER WARRANTY AND THERE IS NO RECALL. I CALLED AUDI. THEY TOLD ME THE SAME THING AND SUGGESTED I CONTACT NHTSA. AUDI ISSUED A TECHNICAL SERVICE BULLETIN IN 2017 ADVISING DEALERS OF THIS PROBLEM AND INSTRUCTING THEM ON HOW TO INSTALL THE REDESIGNED REPLACEMENT KIT. INSTRUCTIONS COVER SEVERAL AUDI MODELS BUT DO NOT SPECIFY MODEL YEARS. TO RECAP, THIS SEEMS TO ME TO BE THE VERY DEFINITION OF NEED FOR A RECALL: 1.DEALER ADMITS THERE WAS A FLAW IN THE ORIGINAL DESIGN. 2. AUDI HAS REDESIGNED THE SYSTEM AND ISSUED INSTRUCTIONS FOR REPLACEMENT. 3. DEALER STATES IT IS DANGEROUS TO DRIVE THE CAR WITHOUT REPLACEMENT KIT. PLEASE ISSUE A RECALL FOR THIS DANGEROUS SITUATION.

I PURCHASED MY VEHICLE IN ORLANDO, FL BACK IN APRIL AND DURING THE TEST DRIVE IT WAS DISCUSSED WITH THE SELLER NOISES IN REFERENCE TO THE PANORAMIC SUNROOF. I LIVE IN TAMPA, FL AND WAS INFORMED BY THE AUDI SOUTH/ORLANDO DEALERSHIP I COULD MAKE AN APPOINTMENT WITH A DEALER LOCALLY TO FIX THE ISSUE. I MADE AN APPOINTMENT AND WAS INFORMED THE GLASS WAS REPLACED AND THE SUN SHADE, HOWEVER THE TRACKING FOR THE SUN SHADE WAS NOT. I HAVE CONTACTED GUEST RELATIONS AT THE CORPORATE OFFICE FOR AUTONATION WHO HAS INVOLVED THE GENERAL MANAGERS OF BOTH TAMPA AND ORLANDO, AND I HAVE MADE FOUR TRIPS TO THE DEALERSHIP AND STILL THE PROBLEM PERSISTS. I HAVE REQUESTED REIMBURSEMENT FOR MY INCONVENIENCE FOR UBER EXPENSES AND THIS WAS PROVIDED BY ORLANDO LOCATION. I RECEIVED RENTAL CAR SERVICES ONCE IN WHICH I WAS INFORMED I MUST PROVIDE MY PERSONAL INSURANCE CARD AND CREDIT CARD IN THE INVENT OF ANY ACCIDENTS BASED ON THE RENTAL IN WHICH I KINDLY OBLIGED WITH THE PROCESS. I HAVE BEEN MORE THAN PATIENT AND UNDERSTANDING, HOWEVER I HAVE NOT BEEN ABLE TO ENJOY MY VEHICLE SINCE THE PURCHASE IN APRIL. MY LAST CONTACT WITH AUDI TAMPA I REQUESTED A VIDEO OF THE WORK PERFORMED TO VALIDATE IF ANYTHING HAS BEEN DONE AT ALL. THIS IS TRULY MY DREAM CAR AND THE EXPERIENCE HAS RESULTED IN PURE DISSATISFACTION. THE VEHICLE CAME WITH A ONE YEAR WARRANTY AND I DO NOT UNDERSTAND WHY NEW REPAIRS CANNOT BE COMPLETED. I CURRENTLY DO NOT HAVE THE DOCUMENTS BASED ON THE TIME OF THIS ENTRY, HOWEVER THIS CAN BE PROVIDED. *TR

I'D LIKE TO POINT OUT THAT REGULAR LIGHTS ON THIS (AND MANY OTHER LATEST GERMAN VEHICLES) ARE OVERLY BRIGHT, IN EXCESS OF THE REGULAR HIGH BEAMS, AND BLINDING TO THE ONCOMING TRAFFIC

Reports whose component NHTSA recorded as unknown, or that do not map to one of the categories above.
From owner reports, verbatim
LOW PROFILE TIRES ON AUDI A5 CAB ARE NOT DESIGNED ROBUST ENOUGH TO HANDLE ROAD. IT HAS BEEN A NIGHTMARE WITH EXCESSIVE TIRE AND WHEEL DAMAGE. I DO NOT RECOMMEND YOU PURCHASE THIS CAR. AUDI WILL BLAME THE ROADS AND THE DRIVER. THESE ARE NOT NORMAL INCIDENTS. FOUR FLAT TIRES AND THREE DAMAGED WHEELS IN LESS THAN 15 MONTHS. SAFETY BECOMES AN ISSUE WITH EXCESSIVE FAILURE. VIBRATION AND ROAD INSTABILITY WILL OCCUR AS THE EASILY DAMAGED WHEELS CANNOT HANDLE THE ROADS

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
