NHTSA Complaint #11464480 — 2013 AUDI A3

Car stalled in fast moving traffic, and then lurched forward. In the stall the car behind me almost ran into me. In the lurch, I almost rear ended someone. Fortunate that both times there was no collision. Took the vehicle to Audi and the car has been diagnosed with failed mechatronic - a $4,000 repair. It was shared that this is a known issue with Audi for my model year (faulty mechatronic), and as such has been recalled in several countries, but not the US. I called Audi USA and was informed that yes it is a known issue and has been recalled in other countries, but that NHTSA has not required Audi USA to open a recall here, and so they can't help me. I'm asking for some assistance. Thank you very much
