NHTSA Complaint #11447242 — 2013 AUDI A6

Steering Rack Assist has a recall for my car because my steering locked up. Audi replaced the recall part two times. the first didnt work after the second time it works but now they cant reset the check engine lights, TPMS, Steering Fault do not drive it says, ECS Fualt, Stability Fault, Child Safety Lock Fault etc. Dealer told they did everything they could even flew in an Audi Engineer still cant reset anything and that they exceeded the cars value in man hours to figure out what is the issue. Now they tell me the car is drivable but my question is, is it safe for me to accept it like that and risk something happening while driving and the steering locking up or any other problems that may arise but I wouldn"t know because of the other alarms may override the current alarm that may pop up. My insurance said they wouldnt accept the car back in that condition because its a recall issue related and that Audi needs to address this but in just getting the run around. My car has been at the dealer for about 6 months trying to figure it out. Now they tell me "You brought your car because steering was locked up wasnt able to drive and now the car is drivable and the only thing we cant clear are the alarms that i mentioned above but it is drivable its just like an oil change alarm that you do the oil change but we just cant reset it so its kinda the same thing" they told me that and i was like okay. No is not the same i said, my question is is this even safe to accept and risk something happen and get into an accident because of the steering lock up. Now they wont even take my wife audi because has the same recall that needs to be replaced. the only way they replace it is till it happens. So they waiting for my wifes car to lock up while driving and not have control of car and crash especially if my kids are with her because she takes them to school. What do i do please help? I also requested the total estimate to see how much I owe and they will not send it to me.
