2016 Dodge Dart: check engine light

Filed Oct 24, 2026 · Electrical, Engine · CA

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.

Anti-lock brake system service light comes on and off as well as the traction control light. The antilock brake system is not working at all and skid control doesn't work either. Brakes are hard to push often and vehicle is more and more reluctant to stop. The vehicle is always in motion. Stearing is harder when the vehicle slows or stops also. The issue began at the same time as the antilock brake issue. Check engine light also came on. All lights where cleared at my last service but came back on immediately from leaving the dealership I serviced it at. I have kids I transport in this vehicle and failing brakes under 90000 miles is a big deal. Approximate mileage is 83000.

Power train & sensors related issues: I was driving on the highway@ 45mph in traffic & all of a sudden the speed idle down to 13mph in traffic without me pressing the gas pedal, I placed my emergency flashers on to let cars behind me be aware I was experiencing problems with my vehicle. The engine symbol illuminated on the dash panel as with a lightening bolt symbol, the vehicle did a surge in speed without the gas pedal being pressed, jerked & surge in speed again & I had to press the brakes to safely pull out of traffic to gain composure of what was happening with the vehicle sudden erractic behavior. No warning before hand. I cut the vehicle off for several minutes. It cranked up & the engine light illuminated still but the lightening bolt symbol hadn't. I called to see of any recalls & there was a recall for the computer module software. I was given a case number for the vehicle from the recall associate to call the local dodge dealership & was told by one of the dodge service associates, his sheet didn't contain that recall & wasn't able to remedy the problem.

Car stalled while driving on a on ramp to the freeway. I pulled over and tried to start it. It sounded like it was trying to turn over by itself for a good 10 seconds. When it restarted, after releasing the break my car thrust forward. Then started to spuber like it wanted to stall again. At that time 3 lights came on on the dash... The check engine, stabilization and another I've never seen. Was real close to a dodge dearer where I bearly made it to. When I asked the person about the tigris light coming on he told me 'that means get it in asap! Something seriously wrong is with the vehicle.' the car has just over 30k miles and I know it's still under warranty.
