Dieseling
I encountered something new today with my TSX V6. At first the car started hard, no big deal since it was cold overnight but when I shut the car off it continued to run for several seconds afterwards. I haven't experienced this in a car since driving my dad's 86 Eagle Wagon back in High School. It was always referred to as dieseling where I came from and that's what this reminded me of this morning.
It might possibly be a bad batch of gas, possibly an electrical glitch but not something that should be occuring in a car with less than 1k miles on it.
No matter what it is I'm calling the dealer in the morning to bring the car in.
Has anyone else experienced this?

I've noticed when I turn the engine completely off and If i press the brake pedal the rear brake light still works without any electrical/engine parts running. Not sure if this is normal though.

How did it run after you turned the ignition off? Did it seem to "run" much harder? Or normal for the few seconds after?
I dunno if it's dieseling, I always thought that was when the spark plug wasn't generating a spark anymore, and the heat off the plug or combustion chamber is what was igniting the air/fuel mixture.

It acted as if it were running out of fuel. It ran a few seconds normally then stumbled and stalled. I don't know if it's diesling either but that was the best way I could describe it.

Sure, but the time from turning the ignition off to rpm reaching 0 should be something like a quarter second.
What if fuel was cut off, but something was wrong with the injectors, causing them to stay open? Could that be a possible scenario?

but then again as you said, the spark should also be removed too, which should put that idea out too
but my best guess would have to be is maybe a sticky main relay or something, that is not turning off when the power is removed/switched off (basically everything will still be powered up, as far as the engine goes)

I think a bad batch is possible, considering the car is brand new. See what the dealer says

This was definetly not the usual stumble that you experiece when shuting the car off, but it hasn't happened since this morning. I was thinking that it might be a possible relay issue as the car would have had to been getting some fuel and spark to do what it did, so it would need power. I'll post what I find out from the dealer.
