Anybody had this happen with their Santa Fe? The engine light came on and we took the car to the dealer. They ran the diagnostics and said eeverything looked ok and reset the light. I drove out of their parking lot and the light came back on. The service manager said to drive the car until I could find time to leave it again. So I drove it for about 1 week when the car began to misbehave. While driving it would buck. The revs would go up to 3000 and stay there. After several minutes of this behavior the car would drive normally. Back to the dealer. Now they find a faulty sensor and tell me the car was in its "Limp mode". Now the car runs normal so I guess things are fixed. I did notice one thing while having this problem. The gas milage actually improved. ?????? R. Larkin
