Q: I have a 2012 Dodge Charger R/T AWD and I have check engine light issues

Hello, thank you for writing in. The long list of potential issues that cause hard-starts and misfires is profound. Without knowing exactly what diagnostic codes the dealership was pulling from the check engine light, it is impossible to narrow down the culprits for you. If you can inform us what the latest codes are, we can have a better idea of what the issues may be. The codes can change just by putting the key in the ignition, as this is when the vehicle starts running self-tests, so scanning it again may bring new information to light. Newer vehicles are so complex when it comes to the electronics that monitor them, that there are several components that may lead to random electrical issues. One thing you should do is run your VIN and see what TSBs (technician service bulletins) are out for your vehicle. This will tell you every single issue the manufacture knows is wrong with the vehicle, and as long as those parts are original, they have to replace them for free. There are TSBs out for your model and year, and some will effect electrical systems. For a second opinion and inspection, contact our service department to schedule an appointment.
