I was driving at highway speed (~65 mph) today when traffic quickly came to a stop and I brake fairly hard. About when the car came to a stop, a "TPMS malfunction" (tire pressure monitoring system) error message came on the dash and the car could no longer accelerate, as the engine was disconnected from the transmission. The gear shift lever was in "drive", but the engine was free-revving as if the transmission was in "neutral". I shifted to "S" (sport) mode - no change. I shifted to "park" and then back to "drive" - no change. Traffic on the highway had begun moving and I was stranded, blocking traffic. After another attempt, I shut off the vehicle and turned it back on. At that point, "drive" engaged properly and I was able to drive back home safely. My vehicle has been maintained properly at all regularly scheduled service intervals. I had not experienced this issue before, but, after reading through blogs, it seems like this is an issue that several Audi vehicles have experienced over the last few years and it's not clear if Audi of America considers this recall worthy. My perspective is that this is a significant safety concern and warrants further investigation, as it is intermittent and acute. In other words, it is unpredictable / recurring and can have a serious impact if it happens at the wrong time, unlike a normal wear-and-tear issue. Thank you for taking the time to consider this incident as one that is worthy of further investigation.

My vehicle is equipped with optional keyless entry/operation called Audi advanced key. I drove the vehicle using the keyless feature for approximately 15-20 minutes to pick up child from school. The key was in my purse and placed in the front passenger side seat. Upon returning home, the car was parked in its usual outside parking spot. I placed the vehicle in park, turned off the vehicle and unlocked all doors using the button on the driver side door (all doors are set to automatically lock upon driving the vehicle above 5mph). Never moving my purse and key from the front seat where initially placed, I exited the vehicle and closed the door to retrieve my child. Upon closing the door, the vehicle beeped and locked the doors automatically - which would have been unusual in any circumstance even if the keys were outside the vehicle. Audi advanced key system should not allow a vehicle to lock when keys are inside the vehicle. This caused my child to be stranded, still strapped to his car seat (2-years old) for over half an hour until the fire department arrived. A call to 911 emergency services was made and fire department responded. The vehicle is well maintained only by an Audi dealership based on the manufacturer's recommended service timeline and has never been in an accident. Potential causes may include faulty cpu programming and/or electrical systems. Based on internet searches, problem appears more frequent than normal - especially with trunk access. Luckily this incident was not during a hot summer day, but can pose risk to small children.

The contact owns a 2012 Audi Q5. While the vehicle was idling at a traffic light, the "change key battery" warning indicator illuminated and the engine stalled. The vehicle would not restart while the key was in the ignition; however, it restarted when the key fob was pressed. The failure only occurred once. The dealer stated that this type of failure occurred when the battery inside the key fob was not charged. The key fob was repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 12,000.
