There are 8 owner-reported electrical system complaints for the 2013 Audi A4in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
After run collant pump caught fire and damaged the engine wiring harness. I reported it to progressive insurance and they came and inspected it at a body shop. They concluded it was due to an open recall on the vehicle so insurance refuses to cover it. Had car towed to Audi dealership and they reported it to Audi USA. They came back and told me that because of the mileage and year of the vehicle that they wouldn't cover it.
Coolent migration from the coolant valve through the wire into the connection to ecu. This caused corrosion which in turn caused an unsafe driving condition by shutting the throttle pedal control to the engine off. This has been recalled on many other models and is quite prevalent in the a4 with manual transmission as mine is.
I HAVE HAD AN EPC AND COOLANT SENSOR ISSUE FOR THE PAST MONTH, BUT IT TOOK AUDI 1 MONTH TO FINALLY INFORM ME OF THE RECALL NOTICE. THEY ISSUED THE RECALL MAY 15, 2018 BUT I RECEIVED THE LETTER JUNE 15, 2018. IN ADDITION, AUDI DOES NOT HAVE A SOLUTION TO REPAIR THE DAMAGED PARTS.
ENGINE AND ENGINE COOLING:COOLING SYSTEM
RECEIVED RECALL NOTICE IN APRIL, ANOTHER LETTER IN JUNE, AND A 3RD LETTER IN SEPTEMBER. THIS IS THE AFTER RUN COOLANT PUMP RECALL 19N4. NO PARTS ARE AVAILABLE AFTER MANY MONTHS, AND AUDI RECOMMENDS THAT CAR BE PARKED OUTSIDE, NOT IN GARAGE. THIS IS UNACCEPTABLE AS WE LIVE IN MASSACHUSETTS AND WINTER IS COMING SOON.
CAR FAILS TO START VIA THE KEY IN THE IGNITION. YOU HAVE TO WIGGLE THE KEY TO GET THE IGNITION TO START. BATTERY IN KEY FOB IS OK AS IT OPENS AND LOCKS THE CAR WITH NO ISSUE. SEEMS TO BE A SOFTWARE, OR LOOSE CONNECTION ISSUE.
I WAS LOADING MY DOGS INTO THE CAR. THE KEYS WERE SITTING ON DASH BECAUSE MY HANDS WERE FULL. I HAD AN 8 MONTH OLD IN THE CAR IN HER CAR SEAT. AS I CLOSED THE LAST DOOR, THE CAR LOCKED WITH THE KEYS AND THE BABY INSIDE IT. I WAS IN A FAIRLY REMOTE PLACE BUT WAS ABLE TO GET THE FIRE DEPARTMENT TO GET THE CAR OPEN AND GET THE BABY OUT BEFORE SOMETHING TRAGIC OCCURRED. IT HAPPENED TO ME ONCE BEFORE WHEN I WAS LOADING MY CAR AND THE WIND BLEW THE LAST DOOR SHUT. BOTH TIMES THE CAR LOCKED IMMEDIATELY. THE AUDI DEALERSHIP SAID THAT THIS KEY IS SUPPOSED TO LOCK THE CAR AFTER A SPECIFIED PERIOD OF TIME, 20 OR 30 SECONDS. AFTER RESEARCHING THEY FOUND THEY COULD DISABLE THE AUTOMATIC LOCKING SYSTEM WHICH THEY DID FOR ME. THIS IS VERY DANGEROUS AS IT COULD HAVE BEEN A VERY HOT DAY WITH A CHILD LOCKED IN THE CAR, PEOPLE NEED TO BE AWARE OF THIS SYSTEM AND THAT THEY CAN LOCK A CHILD OR A NON ABLE BODIED PERSON OR ANIMAL IN A CAR. *TR
SUDDEN ACCELARATION WAS OBSERVED SEVERAL TIMES WHILE DRIVING AUDI A4. HOWEVER, NO ACCIDENTS OCCURED DUE TO THIS. AUDI SHOULD TAKE A LOOK INTO POSSIBLE ELCTROMECHANICAL PROBLEMS IN 2013 AUDI. *TR
