On several occasions while vehicle was stationary at a stoplight or moving very slowly the emergency braking system deployed, with seat belt tensioner activated and brakes applied with characteristic thunk sound. I could discern no threat at the time, but other cars were nearby. Recently, though, while in the middle of a left turn across three lanes of oncoming traffic (the nearest car was a block away) the car suddenly braked to a full stop. Nothing was behind or alongside me. It took about two seconds for the brake to release and I could accelerate forward. If there had been more traffic there could have been a front or rear collision. I took the car to the dealer who kept it all day and did nothing to it. Review of internet sites indicates that this is a not uncommon problem and that Audi has no solution. My son has 2 Audis, (SQ5s), and says this has happened to him in both of his vehicles.
