I have a 2019 Audi Q5 with under 24k miles over the past 4 years of new vehicle ownership. There have been 5+ instances where I am driving under normal conditions and suddenly the vehicle jerks abruptly, slows down to half the original speed (from 65 mph on freeway to 30 mph), gear shifting becomes irregular and the following indicators appear on the dashboard: 1) check engine light, 2) vehicle repair required 3) warning icon w/ triangle around and exclamation point. "Drive system malfunction" note appears on screen. Ignition cycling may temporarily remove the warning indicator lights, however the same exact issue happens once I'm back on the road - sometimes only driving at 20 mph through residential streets. I have taken the vehicle into Audi service centers for immediate repair after each incident, only to have this become a recurring issue. This is an extremely dangerous situation where a vehicle could unexpectedly reduce speeds and potentially result in traffic accidents. I have found many internet posts on this same exact issue which are major concerns of Audi owners.

I received a Safety Recall from Audi of America for my 2019 Audi Q5, I am pleased that the recall is being done. However, the description of what could happen, in the Safety Recall letter, should water enter the Gateway Module does not describe what happen to me when the Gateway Control Module got wet from liquid spilled in the backseat of my car. The 2nd paragraph under -€œ What is the Issue -€œ states in part, -€œ The vehicle remains steerable and the brake system is fully operable. The engine goes into emergency mode and remains in operation with reduced power. -€œ I was driving my 2019 Audi Q5 on December 12, 2021 on a heavy traveled avenue with many traffic lights. As I went thru the second light before entering 1- 20 West the car just shut down and I mean totally stopped. No warning, nothing. The vehicle was not steerable, The brake system did not work The engine did not start, did not go into an emergency mode and did not remain in operation with reduced power. The car was Totally Un-Operable We called 911 for the Police and a Tow Truck. We sat in horrible traffic for more than 2 hours even with the Police. And the car could not be towed with a regular truck because the wheels were locked. Thus another tow truck had to be called so the car could be put on a flatbed truck to be taken to the Audi Dealer. I believe the Safety Notice from Audi needs to be corrected to give Notice that the Gateway Control Module when exposed to water can and has shut the entire system down and the car can become entirely inoperable as I described above. This is a very dangerous situation which may not only cause serious accidents but permanent injuries and death. I shiver now when I think of what else could have happened to us, but for the Grace of God, because we were seconds from getting on I- 20 West when the car just stopped. I appreciate this opportunity to share this information with you. I hope it will make a positive difference for the safety of others.
