NHTSA 5-Star Safety Rating
Steering is the dominant complaint theme for the 2014 Audi S4. Owners frequently describe the steering as notchy or imprecise, particularly at highway speeds and in cold weather, the wheel can feel resistant to input, develop a dead spot near center, or wander left and right on straight roads, requiring constant small corrections to hold a line. A handful of powertrain complaints describe the EPC warning light triggering limp mode while driving, forcing owners to pull over and restart the car to restore normal operation. A couple of fuel system reports describe air bubble formation codes recurring even after fuel pump replacement, with the car stalling or stopping intermittently as a result.

What can fail
The air bag control module has a flawed algorithm. If side air bags deploy during a crash, a second front-end impact may fail to trigger the front air bags.
What the fix does
Audi dealers will update the air bag control unit software at no charge to correct the algorithm.
