While backing our of my driveway the vehicle started vibrating due to engine ignition malfunction but did not stall. At the same time dashboard light went on indicating that engine needed an oil change though the oil was just changed 2 days prior to the incident. Shut the engine off and restarted and engine operated normally except the dashboard light again indicated need for an oil change. Brought the vehicle back to the dealer for repair. After discussion with service representative it was decided to install ignition relay part for the second time. A scan system test regulator test was done with no problem found. Will continue to run vehicle and hope problem corrected.
