Unhappy Engine won't shut off

I love my new 2011 Sonata! But there is one problem that's a real head scratcher. After my car sits in the hot sun for a few hours and I start it and drive it home, the engine won't turn off with the ignition switch. Everything else turns off, like the electronics, the dash lighting etc. but the engine keeps on running. I can even drive it under this condition. Eventually the engine shuts itself off and it's back to normal. But this means that sometimes I need to babysit the car until it the engine decides to shut itself off - like at a restaurant or any other public place.

Luckily, I was able to show the service department this phenomenon but without resuolution as of yet - and they want me to bring it in again when the problem is ocurring which is highly unpredictable.

Any thoughts as to a solution???

Mike

Make sure you have your dealer run your vin # for any open campaigns. Some vehicles had an issue similar to where accesories stayed on all time and adjustment of shifter was the fix campaign number TB1. Again this may not be your problem but I would at least make sure this has been checked.

Cool Shifter check

Thanks for your reply Hyundai Tech person. The dealer has checked the shifter. My car appears to be outside of the problem manufacturing date window but they plan to replace the shifter anyway.

We'll see . . .

Unhappy Shifter replaced, problem continues

There must be a heat sensitive electronic element in the path to shutting off the engine. The engine actually turns itself off when it gets around to it. This suggests some kind of cooling condition that allows the engine to shut off.

Problem still undiagnosed.

The electronics actually do turn off but the engine continues to run and the car can be driven this way. I can turn the electronics back on again by stepping on the brake and pressing the ignition button - and then turn them off again by doing the same and the engine continues to run the whole time.

And then after running on its own at some point, the engine will actually turn off on its own as well - without anyone doing anything - it just stops.
