I drive a 2007 Hummer H2, a truck I generally like the look and feel of. However, their throttle design leaves a bit to be desired.
There is no drive by wire, it's two throttle position sensors in the pedal and throttle body. It measures voltage and opens the throttle a set distance for the voltage. Seems simple enough, right? If there is a difference in voltage between the two sensors though, it shuts the engine down, so if there's a short it doesn't assume WOT, and run away on you. Seems simple enough for a safety feature.
Except I was driving down the road at 50mph going down a long hill when this happened. When this happens, you lose the ability to break or steer. I shifted to neutral real quick to try and restart, but the issue persisted through several attempts. Finally it kicked over with reduced engine power, and I was able to safely pull over to a side road out of traffic.
I can't understand who thought it was a good idea to just kill the engine when this scenario occurs. I'd prefer my regular wire throttle, thank you. And I can't just get the sensor, have to buy the whole new throttle body as it's one piece.
