Open the full vehicle complaint log (all categories)The Gateway control module failed in September 2025 on my 2021 Audi Q5. Vehicle error messages included the following failures: Cruise control, Parking brake, transmission, brakes, and steering, windows rolled down, seats moved, dash and MMI black followed by a sudden loss of power, narrowly avoiding an accident (kids in car). Would not restart. Diagnosis by Audi dealer was that the Gateway control module got wet and needed to be replaced. This is Recall 90S9 from 2021 that was “repaired” in March 2022 by covering the module with a plastic bag. This proved an insufficient repair backed up by a class action lawsuit filed in January 2022 titled Gioffe, et al. v. Volkswagen Group of America, Inc., et al. (Case No. 1:22-cv-00193). I reached out to Audi USA to request a Goodwill repair which was my only available recourse given that the recall had been completed and closed. After 5 days the Regional Manager denied my request even after I emphasized the safety risk associated with this catastrophic failure as well as the recall in 2021 and class action suit filed in 2022. I paid $1485.33 to re-repair the recall. Driving home from repair my vehicle alerted me to the following messages: Vehicle starting system: malfunction! Please contact Service, and Audi pre-sense: currently limited. See owner’s manual. An OBD scan alerted 7 more codes: 1. Steering Assistance ID 44 (Terminal 30 Open circuit), 2. Central Electrics ID 09 (Garage door opener transmitter no communication), 3. Gateway ID 19 Control module for emergency call module and communication unit no communication, 4. Ethernet Notrufmodul keine Kommunikation, 5. Ethernet databus branch 1 No communication, 6. Multimedia ID SF Function restriction due to communication interruption, 7. Driver Assistance ID A5 Dynamic calibration Function limitation due to limit value exceedance.I reached out to the dealership that performed the service and was told that those are “ghost codes” and nothing to do with the work performed.
Every possible warning light came on without notice and the car came to an abrupt halt. Ultimately the front tires locked and the car could not be moved out of park. This happened at Yosemite National Park and was very dangerous. Fortunately I was able to glide most of the car to the side of the road (not all) before the complete shutdown of all systems. The car was towed to our Audi dealer. Audi confirmed that it was the Gateway Module that had completely shut down due to "water ingress." This was perplexing because: 1) There had been a recall to fix this issue in similar Audi's about a year ago and we had promptly taken it in for the fix; and 2) We did not spill any water on the back seat nor drive over any substantial water which in any event should not have resulted in a complete system failure based on the fix that had been prescribed for the recall. Audi indicates they have fixed the issue and applied a sealant underneath as an added measure. We are very concerned about how - after the recall fix - this could have happened and want to know what assurance there is it cannot happen again.
Steering wheel will forcefully and suddenly jerk to the left at random times on at least 6 occasions.
I was driving down a slight hill in 1/2 inch of snow at 5MPH and when I tired to gently brake as I descended the hill, the brake pedal had no resistance and went flat to the floor. I had no brakes. I then tried to steer towards the side of the road and the steering wheel completely locked up and I was not able to steer. I slid 150 feet down the hill and into a ditch. No brakes and no steering. There must have been a failure of some kind. Terrifying.
The incident occurred on a busy road during evening rush hour. I was in the middle lane of three lanes, and the lane to the right of me was closed due to construction. The phrase “electrical malfunction” flashed across my dashboard, there were beeping sounds, and about 5-10 later the steering froze up and the car would no longer accelerate. There were no other prior warning indications. I was unable to steer over on a side road or shoulder. I blocked traffic in the middle lane. My 1-and-a-half-year-old was in the back seat with me, and I was 35 weeks pregnant at the time. The temperature was 104 outside and my car wouldn’t start despite several trouble shooting attempts to turn it back on. The car kept beeping and flashing malfunction signals on the dashboard indicating that all the different safety functions were not functioning. The windows were inoperable as well and would randomly go up and down. The vehicle was towed to the dealership, and they determined the J533 Gateway Module needed to be replaced. This module is located underneath the back row in a tub-like recess, which had collected water, and the module had malfunctioned. It is unknown if the module is available for inspection upon request.
