Common problems with the 2014 S6
NHTSA's file holds 20 owner complaints on the 2014 Audi S6. Owners named the engine most often: 14 complaints, and half of the 8 that list a mileage came after 71,000 miles. A complaint can name more than one component.
| Component (NHTSA category) | Complaints | Listing mileage | Median mileage |
|---|---|---|---|
| Engine | 14 | 8 | 71,500 |
| Fuel/propulsion System | 3 | 3 | Under 5 mileages |
| Suspension | 3 | 1 | Under 5 mileages |
| Power Train | 2 | 2 | Under 5 mileages |
| Steering | 2 | 1 | Under 5 mileages |
Of the 20 complaints, none reports a crash, none reports a fire and 2 report an injury (2 people reported injured). These are owners' reports to NHTSA, not findings.
Mileage when owners reported a problem with the 2014 S6
The 10 mileages owners gave run from 60,000 to 125,000 miles, and half are at or under 71,500. With fewer than 20 mileages this page gives the median only: the other percentiles are too few to say. 1 came after 100,000 miles, none after 150,000 and none after 200,000.
These mileages say when owners reported a problem, not when a 2014 S6 wears out. NHTSA's file holds only vehicles whose owners complained; one that ran without a problem never appears in it, so it gives no lifespan and no cutoff, and how a vehicle was maintained matters more than any one odometer reading.
Most of these reports came early in the vehicle's life: 9 of the 10 came at or under 100,000 miles, so they say nothing about how many miles a 2014 S6 can cover.
| Measure | Value |
|---|---|
| Lowest mileage listed | 60,000 miles |
| 25th percentile | Too few to say |
| Median (50th percentile) | 71,500 miles |
| 75th percentile | Too few to say |
| 90th percentile | Too few to say |
| Highest mileage listed | 125,000 miles |
| Complaints after 100,000 miles | 1 of 10 |
| Complaints after 150,000 miles | none |
| Complaints after 200,000 miles | none |
Is the 2014 S6 a good year?
Complaint counts cannot say whether the 2014 is a good or a bad S6: they rise with how many were sold and how long they have been on the road. They show how the 2014 compares with the other model years in NHTSA's file.
With 20 complaints, the 2014 ranks 2nd of the 3 Audi S6 model years from 2013 to 2016 with 10 or more complaints, counting from the most. The most: the 2013 (42). The fewest: the 2016 (19).
NHTSA files the Audi S6 name for 1995–2003 and 2007–2025. A gap of three or more model years means the name covers different vehicles, so the 2014 is compared only with the 2007–2025 model years.
Recent model years have had less time to collect complaints, so their counts are still growing. No year is ranked by mileage here, because a year's median mileage mostly follows its age.

What these figures can and cannot tell you
- Complaints are owners’ reports to NHTSA. NHTSA publishes them without verifying them: a complaint is an allegation, not a defect finding.
- The mileage is what the owner wrote on the complaint; NHTSA does not check it against the odometer.
- The make, model and model year are the ones on the complaint. NHTSA records them as filed, so a few complaints sit under a model year the name was not sold in.
- They are not a lifespan study. The file holds only vehicles whose owners reported a problem, so these figures do not say how long a typical 2014 S6 lasts.
- A complaint count rises with how many vehicles were sold and how long they have been on the road, so it is not a rating of the 2014 S6.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 10 of the 20 complaints on the 2014 Audi S6 give no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and are left out of every mileage figure.
- NHTSA name counted: S6. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only this one.
- Recall-file name matched: S6.
