The 2014 Jeep Grand Cherokee has been reported to experience various problems with its push button start system. This guide aims to provide owners and potential buyers with insights into common issues, possible causes, and solutions.

Common Problems with Push Button Start

The push button start feature in the 2014 Jeep Grand Cherokee can malfunction for several reasons. Understanding these issues can help diagnose the problem effectively.

  • Key Fob Issues: A common problem is the key fob not being detected. This can occur if the battery in the key fob is dead or if there are interference issues from other electronic devices nearby. If you see a "Key Fob Not Detected" message, try using the fob against the ignition button while pressing the brake pedal.

  • Battery Problems: Many users report that the vehicle may click but not crank, especially after sitting for extended periods. This could indicate a failing battery, particularly in colder temperatures. It's advisable to check the battery's health and connections.

  • Starter or Alternator Issues: If the engine cranks but does not start, it could be related to starter or alternator problems. Users have noted that pressing the button multiple times sometimes resolves this issue, suggesting intermittent connectivity or power supply problems.

Possible Solutions

To address push button start issues in your Jeep Grand Cherokee, consider the following solutions:

  • Replace Key Fob Battery: If you suspect the key fob is not working properly, replace its battery and ensure it is functioning correctly.

  • Check Battery Health: Have your vehicle's battery tested at an automotive store or service center. Replace it if it shows signs of weakness.

  • Inspect Starter and Alternator: If problems persist, have a mechanic check the starter and alternator for any faults that could be causing starting issues.

  • Software Updates: Sometimes, dealerships may have software updates that can resolve electronic issues related to starting systems. It’s worth checking with your local dealer.

Additional Considerations

If you experience persistent issues with your push button start system:

  • Loose Connections: Ensure that all electrical connections related to the ignition system are secure. Loose terminals can lead to inconsistent starting behavior.

  • Intermittent Faults: Some users have reported intermittent starting issues that seem to vary with temperature conditions. Keeping a log of when these issues occur can help diagnose patterns that may indicate specific faults.
