5/5 Overall
NHTSA 5-Star Safety Rating
For the 2018 Audi A4, the complaint set is small at 29 total reports, so patterns are limited. The most notable recurring theme involves the infotainment system, owners describe the MMI screen cycling off and on or restarting while driving, which takes the backup camera offline mid-maneuver. A few owners also note that automatic emergency braking activates unexpectedly when the system loses its display reference. Airbags, powertrain, and service brakes each account for a handful of complaints, but no single strong symptom pattern emerges across those categories. One isolated report describes fluid leaking from the front of the vehicle with no warning lights. The MMI/backup camera intermittent failure is the most consistently described symptom across multiple owners, with several noting the issue is sporadic and sometimes resolves on its own after the car is shut off and restarted.
