1 Automatic Emergency Braking problem

Failure Date: 09/23/2025

My screen turns on and off consistently not allowing me to use my backup camera. Causing a small collision while backing up when the camera turned off unexpectedly. Additionally when it’s off it will auto break when I’m not close enough to hitting and it’s loud and yanked me. This has been an issue for some time and I’m seeing a significant amount of my models have this issue and it’s not safe.

2 Automatic Emergency Braking problem

Failure Date: 08/27/2024

I am reporting recurring safety-related defects on my 2018 Audi A4 involving automatic emergency braking, forward collision warning, Audi pre sense/front-collision functionality, and related electrical/driver-assistance reliability. The aeb/forward-collision system has shown two unsafe intermittent behaviors. At times it has failed to activate as expected when crash-mitigation assistance appeared reasonably available. At other times it has unexpectedly warned, jolted, or applied braking when there was no apparent vehicle, object, pedestrian, or hazard close to the car. Unexpected braking or false intervention can startle the driver, create rear-end collision risk, and reduce confidence in the system. Failure to activate can also increase forward-collision risk. The system was not intentionally disabled by me, and I am not aware of any driver-caused obstruction, modification, or normal explanation. The condition is intermittent and may not appear during a brief service visit or basic fault-code scan. This concern was reported through Audi/dealer service channels, including a documented repair request identifying the aeb system as malfunctioning and failing to activate as designed. A later dealer communication stated that there were no stored aeb faults and later clarified that no work was done on the aeb system, no inspection or verification of aeb operation was performed, and confirmation of operation would require an additional estimate. I am reporting unresolved safety status because intermittent active-safety failures or false interventions may not store permanent dtcs, and lack of stored faults is not complete safety verification. I have not received final written safety closure confirming inspection, calibration review, road-test verification, factory scan/freeze-frame review, module communication review, and technical verification. No crash, fire, injury, or fatality is being reported. The vehicle is available for inspection if requested.
