The backup camera intermittently does not engage, instead only displaying the stock car silhouette, without any camera footage of the current surroundings. This prevents the driver from being able to see anything behind the car and presents a safety hazard when backing up. It presents an additional distraction hazard because it requires the driver to either manually engage the camera using the vehicle's MMI, or to put the car in another gear and then again in reverse to engage the camera. After multiple unsuccessful attempts to have the dealership find and fix the problem over three years, I was told a software update was performed, which is the same fix for a current recall for other models with the same problem. I have only had the car back from the dealership for a week now, but I have not yet experienced the problem with the backup camera.

Multiple warnings indicating to contact dealer (Lane departure, adaptive cruise control, collision avoidance, etc) then 1 minute later transmission failure and engine failure imminent.... pull over immediately and contact dealer. I turned into a road off main highway within a minute of the last two warnings and as I turned, my center MMI went blank then my electronic dash went blank, transmission went into neutral and the engine died all within a few seconds. Fortunately I was able to coast to a stop in the parking lot.

Today, car showed electrical problem then leading to steering problem, transmission problem, all sensors shutting off, all thro flashing one by one alarms and messages on dash and then coming to a complete halt. It would not allow me to come out and locked me in. I could see that the locks were kicking in so took a micro second gap between unlock and auto lock to get out of the car forcefully. I have had situations when in traffic light, the car wouldn-€™t move back from neutral to drive unless I tried couple of times, but this was horrible incident. Now taking it to service to see what they are going to say, not always super helpful.

Car has a lane keeping assistant which is aggressive. Car doesn't allow you to pass parked vehicle such as a ups delivery truck, pedestrians or bicyclists without trying to steer you back toward the object, vehicle or bicyclist you're trying to pass by pulling to the left toward center roadway lines. Almost struck a ups truck after car abruptly steered car back toward the stopped truck, also occured twice while passing bicyclists and once with a pedestrian. I also had trouble merging onto an interstate highway at high speed, signal lights did not override the llanekeeping assist and I literally had to fight with the steering wheel to enter the highway...car finally crossed the lines at a point where I was running out of ramp. Car has been returned to dealership numerous time, found fault codes with cameras and car was reprogrammed. Problem is not resolved and very dangerous. Audi corporate unresponsive. I have manually disabled the system. Note: Reported date below is the date the car would not merge onto I87 South in albany NY. Numerous other occurences over the last several month. Audi albany service department has numerous repair orders. Car is in Audi corporate remedation as a lemon but no conclusion yet. Car should be investigated and recalled serious hazard to pedestrians and bicyclists.

I have a 2019 A6 3.0T quattro with a safety issue when exiting the driver door while auto is in park with engine running. I brought this to the attention of the dealer on 15 July with Audi tech service suggesting to replace door latch and stating vehicle operates "normally as designed" when compared to similar vehicle. The safety issue still exists with having to pull door latch two, three and four times to exit the auto and occasionally having to kill the engine to exit. This is not normal. Three witnesses from the dealership verified my struggling to exit my auto while in park. I was told the 2019 A6S and A8S have this issue and the A8 on the dealership floor is worse than mine. I contacted Audi care advocate line on 27 July and a case # was created. Since then I have contacted several times with absolutely no response. My Audi dealership said no Audi contact was made to them, as I was led to believe would take place by the advocate. As a 30+ year hugely positive Audi customer with my present A6 as my 11th Audi you can imagine my disappointment in Audi's lack of concern and lack of response. I have since posted on the Audi usa facebook and was immediately asked to pm them. I believe the driver door has a "design flaw" which causes an issue with the need to exit in an emergency. Audi is refusing to take responsibility and has claimed to have "documented" my "sentiments and feedback". Audi corporate is ignoring and dismissing what seems to be a horrific new design flaw. Very scary!!
