NHTSA's VIN data lists these trims for the 2017 A4. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 86 complaints with NHTSA about the 2017 A4. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 6 recall campaigns for the 2017 A4 over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.

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.

Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2018 Audi A5 Sportback and 2017-2018 Audi A4 Allroad vehicles. A passenger air bag module mounting screw may not have been sufficiently tightened, possibly affecting the deployment of the air bag in the event of a crash.
Risk: If the air bag does not deploy correctly in the event of a crash, it can increase the risk of an injury.
Remedy: Volkswagen will notify owners, and dealers will inspect the air bag mounting screw, tightening or replacing it as necessary, free of charge. The recall began December 19, 2018. Owners may contact Audi customer service at 1-800-253-2834. Volkswagen's number for this recall is 69Y4.

Risk: The sharp edges of the speaker trim increase the risk of injury to vehicle occupants.

Volkswagen Group of America, Inc. (Volkswagen) is recalling certain model year 2017 Audi A7, A4, A6, Volkswagen Golf and Tiguan vehicles and 2016 Volkswagen e-Golf vehicles for driver frontal air bags, passenger frontal air bags or head air bags that may not deploy properly. Additionally, certain 2017 Audi Q7, A4 Sedan, A4 Allroad, and 2018 Audi Q5 vehicles are being recalled because the seat belt pretensioners may not activate properly.
Risk: In the event of a crash, if the air bags and/or the seat belt pretensioners do not inflate or function properly, the vehicle occupants have an increased risk of injury.
Remedy: Volkswagen and Audi will notify owners, and dealers will replace the affected air bags and seat belt pretensioners, free of charge. The recall began April 2017. Owners may contact Volkswagen customer service at 1-800-893-5298 or Audi customer service at 1-800-253-2834.

The affected vehicles may have been programmed with new software that inadvertently makes the side marker lights inoperative in conjunction with the parking lights or the headlights. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."
Risk: If the side marker lights do not illuminate, the vehicle may be less visible at night, increasing the risk of a crash.
