NHTSA Complaint #11627279 — 2021 AUDI Q5

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.
