2021 Audi Q5 E

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.

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.
