Chevrolet Uplander starting issues with intermittent failure and 'starter locked' message on dash on Chevrolet Uplander

Some Chevrolet Uplander owners report experiencing intermittent starting issues, including a "starter locked" message on the dashboard, which may be linked to the anti-theft system. These owners have found that manipulating wires and the driver's side door lock switch can sometimes resolve the problem. Additionally, some report symptoms of starter motor failure, where the solenoid clicks but the engine does not rotate, indicating a potential malfunction. Common causes also include battery, alternator, or starter issues, with weak batteries leading to clicking noises and insufficient power to start the vehicle. Furthermore, some owners have encountered problems with the starter itself, which may produce clicking, no noise, or grinding sounds when attempting to start. Lastly, issues with the General Motors positive battery cable have been noted, potentially causing erratic behavior in power door lock actuators. It is crucial for owners experiencing these issues to investigate these potential causes to ensure prompt resolution.
