There was a lawsuit, see link below, because the water pump on 2021 Audi Q5’s fail prematurely. My water pump failed at 66,241 miles and I believe that my 2021 Audi Q5 should’ve been covered under this water pump failure recall. However, my VIN was not included. Link: [XXX] I would like the recall on the water pump to be extended to my vehicle as it’s unreasonable that my water pump failed at 66K. Picture of repair in attachments.

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...

Reverse car went full throttle, brakes did not work, car stopped in reverse when it hit a tree. Seat belt did not tighten,

Engine coolant was empty. No indicators about it.

When driving in extreme cold (ambient temperatures of -35 or colder) and I reach a speed of 50mph or higher, my engine fails. The dealership refuses to resolve this issue although they’ve had my vehicle twice now, both for months at a time- and the dealership is 400 miles away from me. They also refuse to authorize the Audi-certified shop in my hometown to perform any type of diagnostics or maintenance work on this vehicle, which would significantly decrease my stress and the inconvenience of shipping my vehicle back and forth. This first occurred within just a few months of purchase of this vehicle, and I am the first owner. I am listing the first time this happened, although it is an ongoing issue.

The contact owns a 2021 Audi Q5. The contact stated while driving 60 MPH, the malfunction warning light illuminated, followed by the vehicle shaking. The vehicle was taken to the dealer for diagnostic testing. The dealer stated that metal fragment was found in the engine, and that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was contacted, and the manufacturer stated that the contact needed to contact the dealer for assistance. The failure mileage was 138,000. The contact stated that the failure mileage was 44,000. Also the vehicle had 2 oil changes, supposed to have 3. The dealership informed the contact that the engine was blown. The dealer would not honor the warranty because the vehicle needed an oil change.

After conducting a $10k forensic review on the car, they found out that the computer was infected with malware and that that vehicle will always put out fm transmitters to get into your cellular devise to hack it Unfortunately, this is the case for this bricked...Need a replacement with transferring the lease over to a similar priced vehicle.

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...

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...

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.
