These are raw counts from NHTSA records. They are not normalized by how many of these vehicles are on the road, so a model that sold in large numbers will tend to show more of everything. We do not publish a composite safety or reliability score.

Airbag system issue
AIR BAGS
Volkswagen Group of America, Inc. (Volkswagen) is recalling certain model year 2013-2015 Audi A4 and S4 vehicles manufactured February 16, 2012, to October 21, 2014, and 2013-2015 Audi Allroad vehicles manufactured March 12, 2012, to October 21, 2014. Due to an improper algorithm in the air bag control module, if a crash necessitates deployment of the side air bags, a second impact to the front of the vehicle may not command the front air bags to also deploy.
Consequence
If the front air bags do not deploy in the event of a secondary impact to the front of the vehicle, there is an increased risk of occupant injury.
Full campaign recordRemedy
Volkswagen will notify owners, and Audi dealers will update the air bag control unit software, free of charge. The recall began on November 14, 2014. Owners may contact Audi customer service at 1-800-822-2834. Volkswagen's number for this recall is 69K5.

What the ratings mean
NHTSA gives the 2015 Audi S4 5 out of 5 stars overall, level with the 5-star median for the 14 comparable 2015 vehicles NHTSA rated in this class.
NHTSA published results for every NCAP test in this program, so the overall star rating rests on a complete set of crash and rollover results.
NHTSA's dynamic test put this vehicle's rollover probability at 9.9% in a single-vehicle crash — the figure behind the rollover star rating, published here because the star alone hides how wide each band is.

How this compares
At 21 MPG combined, the 2015 Audi S4 ranks 18th of 20 compact cars EPA rated for 2015 — 7 MPG short of the 28 MPG median for that group.
That places it among the thirstiest vehicles in its class. If annual mileage is high, the running-cost gap against a class-average rival compounds quickly.
EPA puts annual fuel spend at about $3,600, $900 more than the $2,700 typical for the class. Over five years at 15,000 miles a year that is roughly $18,000, a $4,500 difference against a class-median vehicle.
Tailpipe CO₂ is 413 grams per mile — about 6.2 metric tons over 15,000 miles of driving.
