Three problems related to check engine light on have been reported for the 2018 Chrysler Pacifica Hybrid. The most recently reported issues are listed below.
We took our car in for recall u73 on Saturday morning. It took about an hour and had no issues that day or the next day. On Monday morning, the check engine light came on, and the turtle icon appeared. We were on a city street in motion. We needed to "limp" home - no more than 15mph. We brought it to the dealer (safford, springfield, va) and they supposedly fixed it. They said it was an issue with the u73 update, and they cleared some codes and it shouldn't happen again. Tuesday morning, more lights come on in the car, talking about air bags, and this time the car wouldn't move while we were on the road.
Catalytic converter overheated during operation causing a burning smell in cabin. Visual inspection of converter showed it was red hot and the color of the sun. Check engine light came in and car was not functional. This is related to the botched u73 recall and subsequent rrt.
Was driving the vehicle at 70mph on the freeway. A "thunk" sound occurred and the car began decelerating rapidly despite pressing down on the gas pedal. Check engine light turned on and the car continued to decelerate. Cabin filled with a small amount of smoke. Came to a complete stop and the car would no longer accelerate at all. Turned the car off and then on to get it the final 100 feet to a gas station. Parked and the car smelled like smoke/burning in the cabin and the engine compartment. Turned off the vehicle until a tow truck arrived. When tow truck arrived, turned vehicle on to turn off electric parking brake; all electronics in the vehicle were acting up and could not turn off parking brake for a good 15 minutes. Finally got it off and towed to the closest dealer.
