New Car Assessment Program

The 2004AUDIA4 carries 225 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 10 crashes, 6 fires, 7 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 2004 A4 is fuel system, gasoline with 35 filings, followed by air bags (18) and exterior lighting (14). 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 3 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 2004 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.

20220916FireELECTRICAL SYSTEM

This took place about a week ago. The car was parked in our driveway when the fire started. My husband had returned home just 15 minutes prior to the fire starting. I noticed there was smoke coming in our living room window. Then I looked at our security camas. And saw smoke pouring out from underneath the hood of my car. We tried to put the fire out with our two hose system set up and it wouldn't go out. So we knew it was electrical. We couldn't get close enough to open the hood so I couldn't pour baking soda on it. Two fire extinguishers later like 10 minutes the firefighters showed up and we're able to put it out. They confirmed that the arch came from the battery terminals /cables. Two of the fireman said they'd never seen anything like this before. Then the car tried to START ITSELF as my husband and the two fireman were standing right in front of the Audi. They had to cut the remaining battery cable that wasn't completely burned through before it stopped. My neighbor has a record

PRNDS appeared in red on my dash and then started blinking. Went on line regarding this and read about a TCM switch or a lever switch malfunction.Have an appt with mechanic on 8/26/21. From what I have read we are looking at a cost prohibitive repair of several thousands of dollars. Does Audi have any responsibility? Apparently it is a common complaint with the A4 model. Felt loss of power when decelerating.
