2019 Audi S4: what breaks, and at what mileage
What breaks on the 2019 Audi S4
Only 3 defect reports have been filed with NHTSA about the 2019 Audi S4, which is too few to compute mileage percentiles or a risk score. The reports reported lifter, cam or cylinder-deactivation failure.

Every report with an odometer reading, cumulative, from 0 to 200,000 miles. A curve that climbs early is a car with early problems, whatever its total.

Every reported failure mode
| Failure mode | System | Reports | With reading | 25th | Median | 75th | Per 1,000 | Typical repair | Severity |
|---|---|---|---|---|---|---|---|---|---|
| Lifter, cam or cylinder-deactivation failure | engine | 1 | 0 | — | — | — | 0.1 | $1,800–$7,000 | High |
| Lane keep or steering assist fault | adas | 1 | 1 | — | 20k | — | 0.1 | $200–$1,600 | High |
| Other brake problem | brakes | 1 | 1 | — | 20k | — | 0.1 | $300–$1,800 | High |
Rate per 1,000 uses a fleet-size estimate derived from recall paperwork for this exact model year. It is a lower bound. Repair costs are typical independent-shop ranges for the failure, not figures from these reports.
Recalls on the 2019 model year
NHTSA has issued 1 recall campaign covering the 2019 Audi S4, affecting an estimated 13,888 vehicles. A recall is a different kind of evidence from a complaint: it is the regulator and the manufacturer agreeing that something has to be fixed, and the fix is free for as long as the car exists.
The campaigns cover seats. Whether the work was actually done on the car in front of you is a question only the VIN can answer, and the manufacturer or NHTSA will answer it free.
One caution about reading these together: a recall usually raises the complaint count for the same part, because owners who read about it go and file. The mileages stay informative; the counts get noisy.
SEATS
208,332 vehicles 2021-11-10- Defect
- Volkswagen Group of America, Inc. (Audi) is recalling certain 2017-2020 A4 Allroad, A4 Sedan, 2018-2019 RS5 Coupe, 2019 RS5 Sportback, 2018-2020 A5 Cabriolet, A5 Coupe, A5 Sportback, S4 Sedan, S5 Cabriolet, S5 Coupe, and Audi S5 Sportback vehicles. The cable connecting the seat heater to the Passenger Occupant Detection System (PODS) may have a contact fault, causing the software to misdiagnose a malfunction and disable the passenger air bag.
- Consequence
- A disabled passenger air bag increases the risk of injury in the event of a crash.
- Remedy
- Dealers will replace the connecting cable and either the heating mat or entire seat cover, free of charge. Owner notification letters were mailed January 7, 2022. Owners may contact Audi customer service at 1-800-253-2834. Audi's number for this recall is 74E3. This recall is an expansion of Recall 19V-547 (74D9). Vehicles previously repaired under 19V-547 will need to return for the new remedy.
Recall work is free at a franchised dealer regardless of the car's age. Check the VIN at nhtsa.gov/recalls before assuming it was done.
Every year of the Audi S4
Scores compare each year against other cars of the same model year, so a low number on an older car is a real result and not an artefact of age.
Shorter is better. Years with too few reports to score are shown without a bar rather than as a zero, because no data is not good news.
What the reports on file say
The complaints recorded against the 2019 Audi S4 are lifter, cam or cylinder-deactivation failure (1 report), lane keep or steering assist fault (1 report, around 20k miles) and other brake problem (1 report, around 20k miles). With a sample this size these are anecdotes rather than a pattern, and they are shown because somebody looking at this exact car would rather see them than nothing.
Why this page is short
A model year needs about 8 reports before percentiles mean anything, and this one does not have them. Complaint volume tracks how many cars were sold and how long they have been on the road, so a thin page usually means a rare car, a new car, or a car whose owners do not file.
Other years of the same model do have enough: 2000, 2001, 2002, 2004, 2005, 2006, 2007 and 2010. The mechanical parts are often shared across those years, so their pages are the better guide to what this one is likely to do, with the caveat that a shared part is not a shared production line.
Where this comes from. Every figure above is computed from NHTSA owner complaints and recall records for this exact make, model and year. Complaints are voluntary and self-selected, so treat counts as a floor. The methodology page writes out each formula, and the same numbers are available as JSON.
