I'm on the way to Michigan from Minnesota last night (~700 miles), and at a routine stop on the expressway for fuel, I get to the light off of the off-ramp, and my dash goes crazy with warning lamps. ETC (Electronic Throttle Control) sensor (the "lightning-bolt"), and the ESP (Electronic Stability Program) lights start flashing at me. The jeep starts bucking, brakes are about at half power, and steering is heavy. I make it to the fuel pump, and shut the car down. Fuel it up, and start it back up - It drives completely normal with no warning lamps. Nothing until I finally make it to my destination exit, and the same thing happens. This time I limp it to the driveway, and park it for the night. This morning took it into the Jeep dealership, and explain the problem. I haven't received a call back from them, but researching this problem, it seems like the Wrangler guys have it the worst with these ETC problems. Some say that their car is in the shop for WEEKS!... and some of the time, it seems as if the service dept never really fixes the problem. I hope that isn't the case with my Compass, but I still wanted to see if anybody has had a similar problem with their Compass/Patriot. I'll keep this thread posted with anything that I hear from the dealership.
Dealership called - They are replacing the entire throttle body. I didn't ask any questions beyond, "when will it be done", so I don't have any more information than that. I'll see if I can get a list of any codes it logged from the dealership when I pick it up. If anybody else has any questions that they would like me to ask when I pick it up, feel free to jot them down here.
I was going to bet that it was something with the PCM, and something went haywire in the extreme cold of Minnesota (It was about -18F each morning) - Guess I was wrong.
The Diagnostic stored a High Air Flow Vac Leak, therefore they deducted that it must be a sticking throttlebody, which they replaced.
I'm convinced that leaving the throttle open in subzero temperatures for hours on end is what caused it to stick, if that is in fact the issue - So I'm not too sure that the throttlebody that was replaced had anything "wrong" with it. The front of the jeep was also coated in about a half inch of ice.
Hopefully, I won't run into this again.
