Is Your 2015 Dodge or Chrysler Running Rough?
There’s nothing more frustrating than a vehicle that won’t start, idles poorly, or throws a persistent Check Engine Light. If your 2015 Dodge Challenger, Charger, or Chrysler 300 with the 3.6L engine is experiencing erratic behavior, the root cause is often a failing Engine Control Module (ECM). This component is the brain of your vehicle’s engine, controlling everything from fuel injection and ignition timing to emissions systems and transmission shifting. When it fails, the symptoms can be widespread and confusing, often leading to costly misdiagnoses and unnecessary parts replacement.
From the Diagnostic Bay
We recently had a 2015 Charger 3.6L towed in that was a classic “parts cannon” victim. The owner had replaced the throttle body, all six spark plugs, and two ignition coils chasing a rough idle and a P0300 (Random Misfire) code. The car would run fine for a few minutes, then start sputtering unpredictably. After confirming fuel pressure and spark were good, we hooked up our diagnostic scanner and monitored the live data from the ECM. We noticed the short-term fuel trim values were jumping erratically on all cylinders, something sensors alone couldn’t cause. A quick check of the ECM’s power and ground circuits confirmed they were solid. The culprit was an internal failure in the original engine computer, which was sending faulty commands to the injectors. A pre-programmed replacement ECM like this one had the car running smoothly in under 30 minutes, saving the owner from further headaches and expenses.
Symptoms of a Failing 3.6L Engine Computer
- âś” Check Engine Light: The most common sign, often with communication-related codes (U-codes) or multiple, seemingly unrelated sensor codes.
- âś” No-Start Condition: The engine cranks but refuses to start, indicating a potential loss of spark or fuel injection control.
- âś” Poor Engine Performance: You may experience rough idling, stalling, hesitation during acceleration, or a noticeable drop in power.
- âś” Decreased Fuel Economy: A faulty ECM can’t efficiently manage the air-fuel mixture, leading to your vehicle consuming more gasoline than usual.
- âś” Intermittent Issues: Problems that appear and disappear, often worsening as the engine warms up, can point to a failing computer.
- âś” Transmission Problems: The ECM works with the Transmission Control Module (TCM), and a failure can cause harsh shifting or the transmission going into “limp mode.”
