Default ECM Shorting out on 2010 Sentra

I bought my 2010 sentra back in July 2010. Over the weekend I started having problems with the car and it was jerking while on the highway and the RPM's were all over the place. I took it to the dealership and they told me it probably was a transmission problem. Ok, not a big deal, car is under warranty and has just over 3200 miles on it. The moved the car to another spot and then it would not turn over. No lights, no anything. So there was a bigger problem. Come to find out, the positive terminal shorted out the ECM and ended up burning the computer system. The dealership was great and replaced the terminal and ECM. Anyone else have this kind of problem, or know what would have caused it. The dealership said they are not sure why this happened. Just looking for some feedback or give some insight if anyone is having problems.

There is a problem with the terminal end on the positive wire to the battery. A defect causes them to seperate at the stud that holds it together and it causes voltage spikes. There is a new part to resolve this issue.
It doesn't usually cause any problems other than not starting.

It also shorts out the ECM had 3 already, but I had 5 for no starts or hard starts.

sorry to bring back an old thread...

But what is the outcome/prognosis for these cars? They've had the ECM replaced? Do they keep running into the same problems? or is it resolved?

I ask because I just had the ECU short out because of the recall/battery terminal (11V579000) @ 40k. At 10k I had the TCM replaced too because of a short....
