Hello, thank you for writing in. The vehicle may be having issues with the alternator and voltage regulator. To find out if the alternator is having issues, you will want to have it tested at your local parts store, or test it in vehicle with a voltmeter. The hardest part about diagnosing these types of issues, is that the issue must be occurring at the time. See if you can replicate the issues by to determine what may be causing them. The fuse box, electrical grounds, and battery are all parts that can fail or be intermittent at times. Something as simple as a loose electrical connection can cause this. For more help resolving the issue, contact our service department to schedule an appointment.
