NHTSA recall 18V740000

What's wrong: After the vehicle has been operating in phev propulsion mode, the gas-fueled engine may not restart properly resulting in unburned fuel entering the exhaust catalyst.

Why it matters: The improperly started engine could result in a loss of motive power increasing the risk of a crash or the unburned fuel in the catalyst may ignite increasing the risk of a fire.

The fix: Fca will notify owners, and dealers will update the powertrain controller module software, and inspect and replace the catalytic converter as necessary, free of charge. The recall began November 15, 2018.
