On march 4, while vehicle was in warm-up phase at home, in idle, a sharp snap was heard (later discovered was the electronic throttle body), then vehicle set two codes (p0171, p2173), and immediately went into limp mode (traction control off, throttle body reduced power, ABS for slowing vehicle if being driven above slower speeds for limp mode). We were on a schedule, so vehicle was shut off immediately and we used our other vehicle for transport. Both codes were researched to determine best repair methods. Since the p0171 was a repeat code, and the p2173 was an unfamiliar sae code not normally used on my previous vehicles, a complete disassembly of the intake was warranted. I am mechanically competent due to training and experience and know my own limits of competency and tools for repair. Here are the basics for reference of what was found. 1. The pcv valve (multiaire) had failed at the internal pintle, and was allowing crankcase air/oil to enter the intake at too high a volume. It was replaced. The map sensor set the p2173 code, then failed due to oil intrusion and was replaced. The rapid snapping of the throttle body under pressure uncalibrated the internal throttle position sensors, and could not maintain proper position was replaced. The intake manifold (newer design for the 2.0l i4 without the flapper controls just guide veins for the intake air) main gasket had shrunk in the plastic intake seat channel and was allowing outside air (p0171) to seep past the gasket on the lower lip of the gasket, and was also not sealing between the cylinders (gases were transferring between the cylinders). The throttle body gasket was pristine. During repair, pressure tested intake for leaks, and tubes and lines for cracks. Reading sae code p2173 was determined that code and subsequent limp mode was designed to prevent damage to the plastic intake manifold. It worked.*dt consumer stated the reason for gasket not sealing, blow by-gases from one cylinder to another. Cylinder head was check and plastic intake for warping, the

I was driving about 45 MPH on a country road, after a curve in the road, my jeep"s traction control and check engine light came on as well as the electronic throttle control started flashing. My jeep then went into "limp mode" and I couldn't drive faster than 40 MPH. I'm so glad that I was on a country road because if this would have happened on a highway it would have been very dangerous. I was finally able to get my jeep home and it has been fine since but now I'm constantly worried that this is going to happen again at anytime.

The throttle body control would not allow my jeep to merge on the highway. I was merging on to the highway and as soon as the it got up to 2500 RPM it would not shift. I had to let off of the gas and pull to the side of the road because it started reving all of the way up to 7000 RPM in order to shift. The lighting bolt symbol came on during all of this and stayed on. I tried then to exit the highway and it did it once again, but this time it stalled completely. The jeep would go as long as I didn't go past 2500 RPM. As soon as I got safely off the highway I took it to a mechanic on the same street. I had to replace the throttle body unit and it ended up costing around 530 usd. Now I am having the exact same symptoms before the last time the unit broke.

At 75000 miles, the electronic throttle switch shorted out internally, leaving the car functioning in limp mode, if you tried to go faster than 10 miles an hour it would buck and kick and going up small hills you would loose all power. Had to be towed to dealership for repais. Was on highway doing 60-65 and all of a sudden dropped to 10

Bought the vehicle brand new with 30ish miles on it, on 12apr14. On 19apr14 (about 420 mileage on it) the vehicle stopped in the middle of an intersection. Would not shift/move. My wife had to floor the gas pedal to get it to chug out of the intersection. I got there an hour after she called me. The hood was so hot I could barely hold it when I opened it. Transmission fluid was pouring out. When the tow truck picked it up it poured more fluid out. It was in the shop until 16may14. The dealer said it was a front transmission pump, and was on national back order. I spoke to tx lemon law and they said sounds like a case. I never filed because I was giving the dealer until 18may14, as that would have been 30 days in the shop.
