2018 Audi Q5

The contact owns a 2018 Audi Q5. The contact stated that while driving his vehicle, a start/stop malfunction warning message appeared on the display screen. Once the contact made it to his destination, the vehicle failed to turn off after repeatedly pushing the start/stop button. The next day, the failure persisted and the vehicle was taken to a dealer where a diagnostic was performed. The diagnostic showed that water had traveled from the sun roof drains into the rear left panel and into the vehicle's wiring module. The manufacturer was notified of the failure and informed him that there were no recalls on the vehicle. The vehicle had yet to be repaired. The failure mileage was approximately 72,000.

Having taking the car in for routine service at the Audi dealership, it was discovered that the Right rear spring and lower perch were not in correct position. I had the car inspected by an auto body shop and was told that the perch is hanging down and the spring has tipped sideways. I am having the car flat bedded to the dealer in Hyannis and the next available date on the schedule for the car to be repaired is 9/26/23. I was advised not to drive the car by the dealership until the repairs are made.

As I was driving on the freeway on my way home from work, my car just started giving off warning signals That my brake lights were no longer working and my tail lights were no longer working. Which almost caused a serious accident Due to the car behind me not being able to tell that I was coming to a stop. When I got home I did a little research to see if I can see what the problem was and I come across multiple complaints online about a faulty hatch switch. I took my car into the dealer the next morning for service and the service provider told me that they will have to check my car and more than likely it is the hatch switch and they are aware of it. But Audi doesn't have a recall for something so deadly. faulty hatch switch That controls your brake lights and taillights It's a serious safety concern And should be addressed immediately, people can lose their lives all because of a faulty switch that audi is aware of

Quattro Ultra shift fork inside the rear differential is faulty due to inferior material used in production. This defect is acknowledged in the TSB circa 2020, attached. I have experienced hesitation upon a start up from the stop/start function at intersections and other cross traffic situations increasing risk of collusions in fast moving traffic. There is a warning message that states you may continue to drive but to get service. It operates intermittently. I have the defective part following its replacement on a low mileage 2018 Audi Q5 2.0. that is approximately 5 years old at approximately 41,601 miles.

Warning lights on the dash began to light up about a minute after starting and driving the car. Pulled over, stopped the car and tried to restart but couldn't restart. Apparently water leaked in from the closed sunroof over night and flooded the spare tire well where a control module is located and shorted. Car was serviced by Audi as recommended during the entire time. Had to have the car towed to an Audi dealer and was charged $1,600 to correct after 10 days.

The right rear coil spring broke after only 52,679 miles. The car was NEVER taken off road and most of the mileage was on highways. It was driven by my wife, who is a very conservative driver. The dealer discovered this. The independent shop to which I took it for a second opinion stated that the coil spring looked like new but had a break in it, which they've never seen with a car in pristine condition and such low mileage. Both the dealer and independent shop stated it was a hazard and needed to have both rear coil springs replaced, since although only one was broken it was mechanically necessary to do both. The public Audi Forum [https://www.audiworld.com/forums/] posts show that several other vehicles of the same model and more interestingly the same model year had the same problem. This is clearly a safety issue and a manufacturing defect. I have uploaded photos I took of the coil spring after it was deinstalled from the vehicle.

Passenger backup light failure. Taken to dealer and they recommended replacing part TSB 2063766/2. Yes I will supply this part if requested. No backup light is a safety hazard. Yes the vehicle was inspected by the dealer. They gave a parts and labor estimate of $805. Yes there was a warning message in the dashboard for this malfunction. This is a “common failure” in Audi Q5 automobiles to the point where the replacement part is on back order.

On 8/8/2023 my vehicle was outside in the driveway of our home in Truro, MA. A large storm moved through the area with torrential rain and lightning. Once the rain let up I looked out the window to find all 4 windows down 4-6 inches, the rear hatch was opened with the rear wiper and high middle brake light on. When I ran outside to close the windows etc. I could not start the car the MMI did not come on and I could only get 3 of the windows up. I had to manually close the rear hatch. I put a tarp over the drivers side window that wouldn't close and had AAA come out. They assessed that it was not a battery issue bit an electrical module issue. I filed a claim with my Insurance and after waiting for the adjuster to look at the car I had AAA tow it to an Audi Dealership. They ran a diagnostic test on it and found water had caused the Comfort Module and associated wiring to fail. The estimate to fix the issues was is nearly $12,000. Because of the cost my insurance company is sending another adjuster out to inspect the issues at the dealership. There were no prior issues or symptoms before this issue took place.
