The engine has failed and I am not sure why my Q5 was not included in the recall for coolant issues leading to engine failure. My issue started last winter when the car would suddenly kick in a loud fan. It would flash a warning that the start/stop malfunctioned as it only happened when stopped and/or parked. It was extremely alarming to hear so I would turn the car off and let it sit. When I started it up, there were no warnings and would drive normally. This continued to happen randomly. Then came the coolant low warning, engine temp, along with an RPM warning that kicked on the loud fan. I added coolant as it was the reservoir was low but never empty and temp gauge was in normal range. All messages would go away, car would drive normally. The coolant message happened a couple more times and always the same but eventually did not return. The Max RPM and temp continued in conjunction with the start stop messages. It was always the same. It would be stopped or Parked with the start/stop engaged. The fan would kick on and increase in severity and the temp gauge always was within normal. I eventually stopped using the start/stop function and it seemed to resolve the issue. The warnings never stayed on so I was not overly concerned since it drove fine and didn't sound rough when the messages and warning weren't active. Then it expelled the oil under the hood and gave zero warning lights. I only figured it out when the oil low warning came on. I thought it was weird because I had just checked the level since I see lots of complaints that Audi burns oil. When I opened the hood, I saw the oil. I know this happened suddenly and was not a leak because I was checking may parking spots. I took it the oil change place and it was cleaned up and replaced. I then took it to have the source of the leak identified but a pressure test revealed nothing. Again, no warning persisted and it drove fine. The next time the oil was expelled, it seized and failed.

I leased a 2021 Audi Q5 (VIN: WA1BAAFY7M2[XXX]) in November 2020. 2021 Audi Q5 has gateway module underneath the middle row seat. The gateway module is like the brain of the car and if it stops working the car stops - basically the car is brain dead. In my case, I was driving the car with my family i.e. wife, 7 and 3 year old kids when the car abruptly shut off. Luckily, I was on a road with 45 MPH speed limit and no traffic, so nothing happened to us. If this happened on a highway or other situation anything could have happened to me and my family. After safely parking the car and getting it towed to Audi Westmont, the car was inspected, and I was informed about the gateway module issue. To my shock, the mechanic said that it-??s a design flaw that Audi is aware of but doesn't have a solution yet. Furthermore, he said that just at Laurel Audi in Westmont 4 cars were repaired for this problem. When I googled, several Audi owners have faced this problem. As I mentioned earlier, despite knowing the issue Audi didn't inform the owners and yet to inform the owners despite this being a serious enough problem that could put owners/families in a life threatening situation. Here's the link to the video taken during the diagnosis of the problem: https://asr.autonation.com/tV0Ij5Ym5c. I have also attached picture of the hodgepodge fix i.e. wrapping gateway module in plastic. The reason I say it is hodgepodge is that wrapping in plastic won't prevent water from condensing on gateway module and the problem repeating. Preceding the days my car had this problem, there were heavy rains and humidity was very high, as noted in the video there is no source of water leak or water entering the gateway module externally, given that finding and the fact that there was heavy rains, high humidity in the preceding days - condensation can likely be the potential cause of the problem. There are thousands of 2021 Audi Q5's and every single one has this risk. PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMA

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.
