While driving a brand new Audi Q5 it suddenly went into "Panic mode" with the windows going up & done, Steering malfunctioning, warning the driver to pull over. The car shuts down unexpectedly without reason. The whole car freezes ! While at the dealership, the tech told us there was another car being repaired with the same issue.Turns out if the back battery gets wet(hidden under the back cup holder)the car shuts down. A cup of coffee spilled in the back seat but there are many reports online (part #J533) with any incidence of wetness. Audi is aware of this problem and although they ordered a new part, the problem is NOT repaired permanently.It can happen again and again.Audi needs to have a major recall on all Q3, Q5 and Q7. We were on a residential street when this happened but a multi vehicle crash would have taken place if on a highway.We are asking for a refund since the car was 2 weeks old at the time with less than 5,000 miles. We need the public to know they are driving a car with a a major design flaw and could cause serious accidents.

while driving, my 2021 Audi q5 with 1400 miles, it began to malfunction; every light & warning (transmission, brakes, AWD, etc.) began flashing as failing on the dashboard. The windows begin going up & down. Steering began to be hard. Finally, I was able to steer the q5 out of traffic. Traffic was going about 40-50 mph. 2. the q5 was towed to Audi for diagnostic 3. Audi called & said that the gateway got wet and the cost for the part is $1200. It will take 2 weeks to get the part in. Audi has no openings until October. 4. They stated that the water drains are working and that they found a water bottle cap in the backSeat of the car; therefore, the gateway will not be covered under warranty. Huh" 5. I am unsure why the warranty will not cover any Safety issues on a 4 month old car. 6. Audi is assuming there was a water spill, because there was a water bottle cap in the car. 7. What are you talking about, Audi? Why are you assuming things? What is the real cause of this traumatic experience? 8. Secondly, no one told me not to have a water bottle cap in the q5 backseat area; the q5 without warning, began to shut down. 9. The engine light stayed on. 10. Audi is not acting in good faith, why are there assumptions made" 11. Audi must recall the q5 and announce a public safety warning of the danger that is lurking in the back seat called a gateway. 12. Audi must clearly state -€śDanger! Danger! No water bottle caps allowed in backseat-€ť. 13. Also, not to mention, there were no Audi loaner cars available; this gives off the appearance that Audi is making a lot of repairs and they are aware of this $1200 -€śwater bottle cap-€ť problem called a gateway. 14. I am aware my experience is possibly rare, BUT it must not happen ever. This was a dangerous scary experience that must not happen again to me or any family! 15. Pls demand Audi to recall these q5s to relocate the gateway, before someone dies!!! 16. I will trade in q5 to avoid death...

Water was spilled in the backseat of the car (less than 12 ounces of water). This caused a complete electrical failure impacting the engine and power steering. The failure happened at a slow speed in a parking lot but would have been much more dangerous on highway. The car would not turn on or off and would not shift into any gear after coming to a stop. Was told that the water caused a failure in the data bus control module.

Q5 has a very serious defect, that is, there is a gateway module located under the rear seat cushion/cup holder. All of the communications to all the controllers go through this little box. If water spills, it collects around the gateway and corrodes it, which will shut down the car. This shutdown occurred while I was driving my family. Lost all power, engine, electrical, everything. Barely coasted out of the roadway. This is a design flaw to locate this sensitive module underneath rear cup holders and will lead to dangerous situations for people in the car.
