Two problems related to automatic transmission control module have been reported for the 2016 Dodge Dart. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2016 Dodge Dart based on all problems reported for the 2016 Dart.
The vehicle has experienced recurring engine drivability and electrical problems since 2019, including persistent rough idle, intermittent loss of power under load, repeated no-start conditions, check-engine light illumination, and electrical system malfunctions. In June 2019, an authorized fca dealership diagnosed dtc p0304 (cylinder 4 misfire), identified an ignition-coil boot electrical short, and replaced all four ignition-coil boots under the manufacturer’s 15-year/150,000-mile pzev emissions warranty. The rough-idle condition never fully resolved. In January 2024, another authorized dealership replaced all four spark plugs and one ignition coil and performed pcm-related recall/service work. On August 13, 2026, the vehicle was presented to an authorized dealership with electrical and drivability complaints. The dealer replaced the battery, cleared all diagnostic trouble codes, and documented that repairs were verified. Three days later, the vehicle again failed to start, the check-engine light illuminated, and an independent scan returned u0401 (invalid data received from ecm/pcm a). The vehicle was returned to the dealership on August 22, 2026. The dealer subsequently diagnosed p0118 and replaced the engine coolant temperature sensor under the emissions warranty. However, the persistent rough idle and other reported drivability concerns were not resolved. The dealer represented that bcm, pcm, wiring, power, ground, and communication testing had been performed, but the repair documentation provided does not contain the corresponding test results. Management ultimately declined further diagnostic work. The recurring loss of power under load creates a potential traffic safety hazard. Intermittent no-start conditions also affect vehicle reliability. The vehicle remains available for inspection. The precise underlying cause remains undetermined.
For the past 4 months I've had this same issue. My car turns off while driving I've filed several complaints. The dealership was unable to figure out what was wrong with the car. The reprogrammed the tcm and pcm and that seemed to have fixed the problem up until today, 09/16/2018. I got down the street and my car shut off again while turning onto a busy street. I was almost side swiped and this isn't the first time I was almost in an accident as a result of this.
