One problem related to warnings has been reported for the 2018 Audi A4. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2018 Audi A4 based on all problems reported for the 2018 A4.
The rear-view camera intermittently fails to engage when the vehicle is shifted into reverse. When the camera does display, the image sometimes shows horizontal glitch lines/artifacts. This affects backing visibility and parking safety and creates a risk of collision with pedestrians, objects, vehicles, or property. The concern was reported to Audi service along with other electrical/driver-assistance symptoms, suggesting a possible camera, wiring, module, signal-processing, or broader electrical fault. No crash, fire, injury, or fatality occurred. This complaint is being submitted because the rear camera/reverse display is a backing-safety system and the intermittent failure is unpredictable. The vehicle/component is available for inspection, and photo/video evidence and service communications are available.
