Some Dodge Charger owners report experiencing starting issues after replacing the throttle body and gas pedal, often related to the need for an Electronic Throttle Control (ETC) Relearn procedure. Failure to perform this procedure can lead to rough engine performance and the setting of Diagnostic Trouble Codes (DTC). Additionally, some owners have encountered fuel delivery problems, such as issues with the fuel filter or fuel pump, which can prevent sufficient fuel from reaching the combustion chamber, resulting in the engine cranking but not starting. Ignition system malfunctions have also been reported, causing the engine to crank without firing up. Furthermore, a weak or dead 12v battery may lead to slow cranking or failure to crank at all, necessitating a battery voltage test to identify the issue. To resolve these starting problems, it is important for owners to ensure the ETC Relearn procedure is completed, check fuel delivery, inspect the ignition system, and verify battery condition.

Some Dodge Charger owners report experiencing symptoms of alternator failure, such as smoke and noise, which are not typically associated with this issue. These owners often notice common signs like the red battery warning light illuminating, electrical problems, dimming lights, slow cranking, dead batteries, and stalling engines. Additionally, some report hearing unusual noises, such as whining or grinding, alongside dimming interior lights and headlights. When replacing a faulty alternator with a rebuilt unit, some owners emphasize the importance of ensuring the rebuilt alternator is high quality and compatible with their model, as sourcing from reputable suppliers is crucial for reliability. For those unfamiliar with automotive repairs, many owners recommend seeking professional assistance to accurately diagnose the problem and install the rebuilt alternator, as qualified mechanics have the necessary expertise and tools to minimize the risk of further complications. Promptly addressing alternator issues and replacing faulty units can help restore the Dodge Charger's performance and safety.
