On the 2022-2025 Audi A4, a recurring complaint on newer A4s is the rearview camera showing a black screen, delayed image, or an unavailable message when reverse is selected. Because the camera is a required safety feature, intermittent failure is more serious than a typical infotainment glitch and is often reported alongside MMI instability. The root cause can be software faults, camera module failure, wiring/connectivity issues at the trunk lid, or infotainment communication errors.
Scan the parking aid and information electronics modules for camera communication faults, then verify power/ground and inspect trunk harness routing for damage or loose connectors. Dealers commonly apply software updates first; persistent failures may require replacement of the rear camera or related control module followed by calibration/coding. If the issue is intermittent, documenting ambient conditions and whether the trunk was recently opened/closed can help isolate a harness fault.

On the 2022-2025 Audi A4, owners of 2022-2025 A4s report infotainment instability including black screens, frozen MMI menus, random reboots, loss of Bluetooth/CarPlay audio, and backup camera delays. These complaints are well documented across owner forums and dealer service visits, and Audi has issued software-related service information for MIB3 infotainment concerns on contemporary models. The issue is usually software-related, though some cases involve a faulty display, control unit, or communication fault on the infotainment network.
Confirm whether the vehicle has the latest MMI/MIB3 software and campaign updates installed, then scan the information electronics module for stored faults. Dealers typically perform software updates, parameterization, or replace the infotainment control unit/display if the problem persists. If symptoms occur only with a specific phone, re-pair the device, update the phone OS, and test with wired versus wireless CarPlay/Android Auto.

On the 2022-2025 Audi A4, multiple late-model Audi/VW MQB-derivative vehicles, including B9.5 A4s, have owner reports of repeated low-voltage warnings, dead batteries after sitting, and intermittent no-start conditions. The pattern is commonly linked to control modules not entering sleep mode properly, telematics/connectivity functions waking the network, or a weak AGM battery that tests marginal but repeatedly discharges. Owners typically report the car needing jump-starts after short parking periods and warning messages about electrical system malfunction or battery charge.
Diagnosis should begin with battery state-of-health testing, charging-system verification, and parasitic draw measurement after the vehicle is allowed to sleep. Dealers often update software for gateway/telematics modules, check for excessive quiescent current, and replace the 12V AGM battery if it fails load testing; battery registration/coding is required after replacement. If draw remains high, scan all modules for wake-up faults and inspect accessories such as dashcams or OBD devices.

On the 2022-2025 Audi A4, owners have reported persistent front brake squeal, vibration under light braking, and rotor hot spots or uneven pad deposits at relatively low mileage. This is a known pattern on many modern Audi models using aggressive pad compounds, especially when the car sees short trips or light brake use that prevents proper bedding. Some vehicles receive pad/rotor replacement or revised hardware under warranty, while others improve after proper bedding and cleaning.
Inspect pad thickness, rotor runout, and rotor surface condition for transfer-layer buildup or scoring. If hardware is within spec, a proper re-bed procedure may reduce noise and judder; otherwise replace pads and rotors as a set and lubricate contact points with the correct brake paste. Verify caliper slide function and wheel torque because uneven clamping can worsen pulsation complaints.

On the 2022-2025 Audi A4, panoramic/sunroof-equipped A4s continue to generate owner complaints about water entering the cabin, usually from clogged drains, disconnected drain tubes, or seal alignment issues. Owners often first notice damp headliners, wet front or rear carpets, musty odors, or intermittent electrical warnings after heavy rain or car washes. If water reaches under-carpet wiring or modules, repair costs can rise quickly beyond a simple drain cleaning.
Inspect all sunroof drains for blockage and verify that each drain tube is properly attached and flowing. Check the sunroof frame, cassette seals, and door vapor barriers if the leak source is unclear; then dry the interior thoroughly and inspect under-carpet connectors/modules for corrosion. Early intervention is important because mold and wiring damage can turn a minor leak into a major interior electrical repair.
