Event occurred within 2 days and 50 miles of recall 95B service being performed on 2022 Jeep Grand Cherokee 4xe showing passing results. After startup of the vehicle and being placed into ‘electric’ only drive mode and DRIVE engaged, the vehicle traveled down the driveway approximately 10 feet when the vehicle juddered, the driver display showed an error message ‘Service Hybrid Electric Vehicle System’, a red wrench icon appeared in the dashboard/instrument cluster, and the vehicle automatically switch into ‘hybrid’ drive mode and started the gasoline motor. The vehicle was turned off, then restarted. Upon restart the error message was not visible and the red wrench icon was gone. Vehicle was then able to be operated in full electric drive mode. My safety was at risk because if the sudden juddering and loss of power occurred at speed on the general roadway instead of in my driveway I could have lost control of the vehicle and crashed. I do not know if this has been reproduced by the dealership but I have heard anecdotally about other 4xe drivers having this same issue immediately after the 95B recall service was performed. The vehicle is scheduled for inspection with a Jeep dealership on 1/21/25
