Dodge Dart misfire problems

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.

My car has an extremely bad rough idle. I’ve had an alignment done, new tires, new spark plugs. I’ve done so much work to this car. I have done some extremely deep research and it is a VERY common issue in the 2013 Dodge dart. One thing I also read, is it could be caused due to all of the ground point nuts being painted over, not creating a strong circuit for the ground. That should be a recall because I cannot physically replace all of those nuts. If that’s not the issue, there needs to be an investigation to figure out why this car feels like it will stall out, or I’m going to lose a tire going 65 on the interstate. Something isn’t right with this car and the dealership needs to diagnose it for free knowing it’s such a common issue! I have a very trusted, fully certified mechanic, he has looked at my car, and he is stumped too. No one can figure this out

I have had nothing but issues with my 2013 dodge dart limited. I purchased it with 36,900 miles on it back in july of 2016. Here we are in july of 2020 and the car does not even have 67,000 miles on it. My problem listed was created only roughly a week after purchasing. The entire uconnect system makes my vehicle unable to operate safely. Whether it's the screen going black where I can not control/change anything. The touch screen is everything volume, HVAC, bluetooth, 'supposed to work with remote start. I have had my codes checked; cylinder 1 module misfire. After doing research and my vehicle being stuck unable to drive because it simply would not start(acted like it would but would not.) for the entire winter of 2018. Come summer of 2019 the air was still horriblebut my infant was now in the vehicle. Seeing a poor newborn have sweat rolling off his face on a way to a doctors appointment probably is what done me in the most. This vehicle has some cool uconnect bells and whistles but it is like they attempted to put something in a vehicle that was not capable of handling all the advancements. I have had my car to the dealership 4 times.I've replaced parts within the HVAC twice! Now my odometer is blinking; red flag.I am seriously scared to drive this vehicle. It sits for most of the time.in the lasr 2 years I've maybe driven it a total of 5,000 if that! I have my car almost completely paid off and have not even been able to put over 31,000 miles on it in 4 four years!how absurd and ridiculous! The dealership always want to run a diagnostic even though they have mentioned the issues each time I've paid for them previously. They just have 'quick fix' as the gentleman told me for this. I am a single mother going to college that cannot financially afford all this! The car randomly after being shut down will not restart. Been stuck for a couple months now in the garage.

I have been experiencing pretty much every recall that is on the list number one it started with my car check engine light coming on. And the codes that kept on coming up or for the plugs and coils. I would replace them and they would just go bad again in like a week it is causing my car to do what seems like it's misfiring. My tire light is stuck on when the tires are fine. The speed control stops working on and off. When I steer there's a loud clicking noise. Whenever I try to shift here lately sometimes it won't go into gear. When I turn on the AC it will cause the car to misfire and the only way to make it stop is to turn off the AC and restart the car sometimes three to four times before it stops messing up.today the scariest thing of all happened I was pulling out of bronze and white smoke billowed out of the car tailpipes I'm not sure why. The car is also sporadically not going in gear when I am on the highway making me worry that me and my five kids are in danger due to someone raikkonen to me because my car will not go up to speed and will not shift into the right gear and misfires and will not go over like 30 miles per hour and putz. I replace parts and it seems to work well for a week or two but my car is not on the recall list they say that every single thing that is on the recall list is happening to my car. I don't know what to do about all of this I honestly you just think that dart needs to take the car back.. Like recall it completely. This car has been nothing but trouble after the first year of driving it.

Dodge darts of this model year including mine have a problem with the turbocharger. Problems within the setup create a "turbo underboost" condition, which prompts a check engine light, and throws the car into limp mode. This is often accompanied by a lack of power from the engine and a rough idle, or stalling at idle. In my case it happened while I leaving a city, and I did not have the power to accelerate to highway speed. After pulling over and re-starting the car, this issue is temporarily resolved. This is such an issue with this model year that there is a north america wide back-order on the new-turbo with this issue corrected. For many like me, this expense is out-pocket or for a lucky few, still covered by factory warranty. I believe that the frequency and severity of this issue warrants a recall and proper fix if the turbocharger setup. The issue is corrected on 2014+ model years, which is an indication that fca was aware of the issue.
