Got my Hybrid back today after a week in the shop. They only test drove it 6 miles though...what's with that? There were computer updates done, replaced a fuel value and corrected some recall items. Hopefully I won't have to see them again until I turn in the lease in 2.5 years.

Hi Mary, I hope the computer software updates performed were the ones that will correct the shutdown issue. The replacement NVLD valve, active air flap, and headliner service bulletins would not be the cause of the shutdown you have experienced. Engineers have narrowed the issue down to a software problem that they say will be corrected with updates rather than new parts. I just had it done, and although they test drove it 40 miles and I drove it another 16, it still has not proven to be the permanent fix yet, at least to me. I must say it is running great as of yesterday and I got some really great mileage on the ride home, but only time will tell if it is the permanent repair.
Good luck, Vinny.

As a tech turning wrenches for a dealer in the Piedmont Triad, I can for sure say that these Hybrids have been a thorn in my side. I see more hybrids roll into the service department on the back of tow trucks than any other car. CEL/MIL issues, car won't start, car won't drive, car shuts off, car shakes/stutters. Engineers stop by on occasion to look at the cars, but usually scratch their heads and reload the ECM. I see it as job security, but I'd hate to be the guy that had his car sit here for 4 weeks, only to bring it back in a week later.
 
As krypto said, "Hyundai must be getting close to correctly diagnosing the CEL and power loss issues and developing remedies for both.
Fingers crossed . . . . . ."

It's been almost 3 weeks since my car has had the software fixed, and last week I had all the October service campaigns performed. My car is running much better now and I seem to be getting slightly better mileage and a lot less first start up jerkiness. Most importantly is that I have not had the loss of power issue since the repair. If anyone has an issue with the charging system loss of power, bring the vehicle to the dealer and get the latest service campaigns which should fix the problem.

#30 of 31 3 month old hybrid stopped twice so far by ncdrivers

Driving, I felt a jerk in the car, the ready light flashes and the wrench symbol shows up. The car is on battery power only. I coast on battery till I can pull into a parking lot. Shut the car off. Luckily both times it started back up. Bob King Hyundai in Winston-Salem says they don't know why it would do that.
We are waiting on some parts that are updates. I have copied the posts here and plan to show them to the dealer.

I had the same issue happen to me 4 times earlier on starting in June, along with some other hybrid owners.
The service campiagns will take care of the shutdown issue, and they will also replace the high voltage connectors as well.
If there is any confusion at your dealership, I suggest you go on the Hyundai-Forums.com site and P.M. Car Tech Dude. He is responsible for the development of the repair campaigns and he will personally contact your dealer and tell them exactly what to do to repair this for you. He is a good guy who will get this taken care of for you.
Here is a link to one of the threads regarding the same issue you are experiencing, and you can contact him through it:
