Thanks, I'll keep this in mind the next time I bring it to the dealer.

I laughed out loud at the service advisor when he explained "normal characteristic and asked that he put that on paper, which he did. I said I'd be back the next time it happened and that they would need to have a factory representative available to explain how that characteristic is normal for any vehicle.

I have a 2007 MKX with 16,000 miles. Great vechicle. I am experiencing a problem that when setting at a stop light/sign, the engine's RPM speed will jump 1,000 RPMs to around 1,500. Several times the increase has been so severe that I had to hold the brake to the point that I experienced a POP and a yellow "wrench" symbol came on the left side of the dash. The CUV drove so poorly afterwards that I had to pull over to the side of the road and shut off the engine. This reset the wrench symbol. I've had it to the dealer twice. The first time "no problem". This time, I'm being told it a "normal characteristic of vechicle" to which I called BS. I've owned many cars and have never had an engine's RPM jump like this. Anyone else having this experience?
