Need help,drove home last night car running great, put in park then turned off locked up. got up went to car to go to work put keys in ignition then all lights on dash lit up, but then when i turned ignition to start car kept getting error messages one after other and would not turn over engine just nothing, kept trying still got the same error messages, then left it for an hour went back still the same problem but noticed ignition lights would not stay on as i kept trying could it be park brake or battery, any hepl appreciated.

 

My first suspect would be the battery or the positive battery cable/connection to the junction box.

If it's not as simple as that, post in the X350 tech forum for advice from members with the same model.
