Details
Issue: On certain vehicles, the passenger occupant detection system (PODS) may malfunction. This could cause the airbag system to turn off the passenger-front airbag even when a passenger is seated. Note: This problem would cause an error message to display on the instrument panel and a warning chime to sound. The airbag indicator light would also display "passenger airbag off". Additional note: For the 2020 model year A5 model, only the A5 Sportback is affected by this recall. Safety Risk: An airbag that is turned off could increase the risk of injury to a passenger in a crash. Corrective Actions: Audi will notify owners by mail and instruct them to take their vehicle to a dealer to inspect the front passenger seat. Depending on the seat type, the dealer will either replace the seat heating mat including the connecting cable or the entire seat cover.

On certain vehicles, the aluminum trim on the front and rear door speaker covers could come loose. If this were to occur, the loosened trim may bend away from the speaker cover and could expose sharp edges, which could increase the risk of injury to occupants. Correction: Dealers will remove the aluminum trim from the speaker covers and replace the trim with an updated part. Note: For the A5 model, it is only the A5 Sportback that is involved in this campaign.

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. …
An Audi dealer installed 245/40R18 93H tires on this 2018 Audi A4, while the vehicle placard/specification requires 245/40R18 97H. The lower load index reduces capacity from 1,609 lb per tire to 1,433 lb per tire, approximately 704 lb total across four tires. This creates a safety risk because load-rated tires affect …
The engine oil level has been gradually dropping and has required monitoring and/or adding oil between normal service intervals. The exact source is unknown. It may involve abnormal oil consumption, an external oil leak, internal engine oil consumption, PCV/oil separator issue, turbo-related oil consumption, gasket/se…
The vehicle displayed a low coolant warning and the coolant reservoir was low. Audi dealer service records dated on or about 02/14/2025 document the concern as: “client states low coolant warning was on, coolant reservoir is low, diagnose and advise.” The dealer performed coolant-related work involving the thermostat …
The sunroof has a recurring mechanical/electrical malfunction. During operation, the sunroof binds and makes a loud popping or cracking noise, and the rubber seal became torn or damaged. This suggests a possible track, guide, cable, motor, regulator, frame, seal, or alignment failure. This is being reported as a safe…
Visible wiring has become exposed in the windshield/A-pillar area. There is no airbag/SRS warning light at this time, and I am not able to determine from visual inspection whether the exposed wiring is related to the restraint system. However, this is a safety-sensitive area because it can contain or route electrical …
The exterior side mirrors have intermittent electrical/memory malfunctions. When locking the vehicle, the side mirrors begin to fold, pause or glitch briefly, and then continue folding. Separately, when the vehicle is shifted into reverse, the right-side mirror tilts downward to assist with backing/parking, but when s…
The fuel filler door/gas door intermittently fails to open, preventing normal access to the fuel filler area. This appears to involve the fuel door latch, release mechanism, lock actuator, body component, electrical control, or related wiring/module issue. This is being reported as a safety concern because inability …
The vehicle intermittently gives a false proximity/collision warning while stationary or while maneuvering at low speed. The sensors beep and display a warning on the screen as if an object is about to hit the vehicle, even when nothing around the vehicle has changed and no object is present. This appears to involve t…
The short-term MPG / fuel-consumption display gives illogical and inconsistent readings. The display can show a significant drop in short-term fuel economy after the vehicle has been parked, locked, and not running, as if the system is incorrectly factoring parked/off time into the MPG calculation. This suggests a pos…
