- Engine overheats and produces smoke from under the hood, sometimes tied to a failed water pump or thermostat.
- Vehicle stalls or loses power while driving, in some cases followed by smoke and fire from the engine bay.
- Owners report engine fires starting near the valve cover and wiring harness, which some link to rocker arm failure on the 3.7L engine puncturing the valve cover and spilling oil onto hot engine parts.
- Excessive blue-gray smoke from the exhaust at startup, which one dealer attributed to water vapor and another addressed by replacing PCV valves.
- Vibration or shaking at speeds above 45 mph and when coming to a stop, resembling a tire or brake defect.
