The warning light that says "check charging system" on the Acura TL indicates that the car's diagnostic system has detected a low-voltage battery. Ignoring this warning could lead to the car dying or stalling. Signs that the battery needs to be replaced include difficulty starting the car, problems with cranking, and a lack of interior lights or chimes. Other less common symptoms include a clicking noise in the ignition and issues with firing spark plugs and the starter solenoid due to intermittent charging. A drained or discharged battery could also be caused by a faulty alternator. If the car's warning light comes back on after replacing parts, it's worth considering a possible internal battery drain from the Acura's stereo or Bluetooth module, if present.
