Question about 2007 Hyundai Veracruz SE
OK, folks, here's the scoop. The dealer took our Veracruz in for diagnostic testing and determined the cause of the problem was the actuator for the Electronic Transmission Control system (ETC).
Apparently, in later model cars like the Veracruz, a computer controls the transmission as well as the engine for optimum performance.
If the computer detects a severe enough fault in one of the components of the ETC (e.g. bad sensor, bad component, etc), it places the vehicle in limp home mode.
Based on my experiences, when in limp home mode, the transmission is forced to stay in 3rd gear, the engine will not exceed 2000RPM, the accelerator is not responsive past 2000RPM, and the engine runs rough (probably because the mixture is changed to very rich). The philosophy here, as was explained to me by somebody who works for Hyundai, is to allow the vehicle to continue operating long enough so that it can be driven to a safe location or for service.
I asked whether or not this limp home "feature" could be disabled at the dealership, but apparently it cannot.
I have alerted some folks at Hyundai Motor USA to this thread so they can do further research if the problem begins to affect more individuals than just us three.
FYI - I am in no way shape or form a mechanic or mechanically-minded, so if I have explained anything correctly, I will gladly accept further corrections/explanations from an expert or mechanic. :)

I was advised (by my cousin, an Audi mechanic) to try disconnecting the battery for about a minute, then reconnect. The light was gone, and I've had no issues since. He'd explained to me that it could be just an error on the computer, but if the light comes back, get it checked.
I had started my suv without letting it warm up, and that's what had caused the error in my case.
Tip: make sure you don't leave your keys in the cab when you do this. They might get locked in there when the battery resets. :)
