Automatic Transmission Torque Converter Problems of Infiniti G37

We picked up our brand new Infiniti G37 sedan out of town (52 miles on it) and the next day, drove it home 300 highway miles. Obviously, we were extremely fortunate the problem didn't begin on the trip. By the second day, the car started dying when we came to a stop. At first, the problem didn't happen every time we slowed down, and we discovered putting the car in neutral proved helpful. We hoped it was a fluke that would quickly abate. Unfortunately, by the next day, the problem worsened, and the check engine light went on. We took it to the local dealer, and with Infiniti, they determined the torque converter was locking, and the car needed a new transmission/drive train - apparently, they found a po744 error code. This is our 3rd Infiniti, and we've never had a single mechanical problem with the others, and both dealerships (the one we purchased from and the local one handling the service) claimed they'd never seen anything like this on a new car. I'm afraid what might have happened had we needed to stop suddenly in traffic. To reinforce the magnitude of this problem, the warranty repair estimate (thus far) stands at $11,000 (retail would be $16k+). In light of how significant the problem, I'm scared to drive a vehicle which immediately required this type of repair. Infiniti's consumer assistance department has turned the file over for review but will only look into whether the situation qualifies for replacement under applicable lemon laws. They won't consider owner loyalty or problem magnitude of the problem, and I remain very concerned about future safety.
