The 2003AUDIA4 carries 282 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 11 crashes, 14 fires, 14 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2003 A4 is fuel system, gasoline:delivery:fuel pump with 27 filings, followed by power train:automatic transmission (18) and power train (18). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 4 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.
NHTSA currently has 9 investigation files overlapping the 2003 A4. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

The coolant light came on after I replaced coil packs and I stopped to look wasn't leaking anywhere. Drove to work and it caught on fire due to overheating I guess not really sure. I was driving a car on fire down a highway and didn't even know it. I stopped to take a left turn into work and smoke stared billowing out and around the entire car. Other drivers couldn't see me or nothing I could have been in an accident. The fire department checked the car out sort of and it's in a mechanics shop now. Trying to figure it out. Oil light was on and that's it. AN then the coolant light would kick on and off. Nothing else after I changed the coil packs. And it was well after I did that.

THERE SEEMS TO BE A FUEL PUMP OR OTHER ISSUE ALONG THE FUEL LINE. RECENTLY, THE GAS CAP INDICATOR HAS GONE OFF, AND WON'T TURN OFF. I EVEN TRIED REPLACING THE GAS CAP WITH A NEW ONE. I CHECKED FOR LOOSE PARTS ON TOP OF THE GAS TANK (THROUGH THE TRUNK). NO VISIBLE ISSUES, BUT I DO SMELL GASOLINE ON HUMID DAYS, THERE IS CLEARLY AN ISSUE ALONG THE FUEL LINE. I NOTICED THERE WERE RECALLS BY AUDI FOR DIFFERENT VINS (NOT MINE), THAT HIGHLIGHT ISSUES WITH THE FUEL SYSTEM AND FUEL PUMP - RECALL NUMBER 06V017000 (01/23/2006), AND 07V375000 (08/28/2007) (OTHERS?). I'VE TRIED CALLING AUDI TO SEE IF THEY'D BE WILLING TO INVESTIGATE WHETHER A BROADER NUMBER OF VINS NEED TO BE INCLUDED IN THE RECALL (INCLUDING MINE), AND THEY REFUSED TO COVER COSTS TO LOOK INTO IT.
THE CONSTANTLY VARIABLE TRANSMISSION (CVT) OF MY 2003 AUDI A4 CABRIOLET 1.8T WITH JUST 86,000 MILES ON IT IS FAULTY, AND HAS CAUSED MY VEHICLE TO STALL OUT ON FOUR OCCASIONS, TWICE WHILE ATTEMPTING TO COME TO A STOP AT A STOP SIGN AND WHILE PARKING, AND TWICE WHILE OPERATING THE VEHICLE WHILE ACCELERATING AT A SPEED OF 35 AND 60 MPH, ON A CITY ROAD AND ONCE WHILE ATTEMPTING TO MERGE ONTO THE INTERSTATE. THE VEHICLE MUST BE RESTARTED TO DRIVE, AND HAS JUST BARELY SPUTTERED BACK TO LIFE IN MY FOUR EXPERIENCES SO FAR. AUDI IS AWARE OF THE PROBLEM, AND HAS SETTLED A CLASS ACTION LAWSUIT IN THE PAST, ALTHOUGH THE SETTLEMENT EXPIRED MORE THAN TWO YEARS AGO LEAVING OWNERS LIKE MYSELF ON THE HOOK FOR COSTLY REPAIRS, AND LEFT WITH AN UNSAFE VEHICLE IN THE MEAN TIME. AUDI SHOULD RECALL ALL AUDI A4 1.8T CVT TRANSMISSIONS FROM 2003 TO 2006 AND PERMENTANTLY SOLVE THE PROBLEM BEFORE SOMEONE IS SERIOUSLY INJURED.
