Wife and daughter were driving the car when it started to jerk and pull back and limit the speed and acceleration. They were on the highway and continued to the Jeep dealer which happened to be within a few miles. The dealer saw the engine light on and explained that the reason the car was restricting the speed was a safety restriction because it had detected an engine issue. They left the car overnight and they Technicians were unable to find a code or analyze the issue because they could not recreate it. I'm still waiting for the results.
