Power stearing sometimes does not engage when starting the vehicle

Hi - I am Dave, contributing to RepairPal and providing expert advice since 2010. This requires hands on testing with diagnostic equipment and inspection of the various components that engage the electoric power steering in this vehicle. Being that you just obtained the vehicle it would appears there was a pre-exisitng issue you did not know about. There are various components in the system that must be checked in troubleshooting. This is a major safety issue, so I suggest having this tested and repaired before attempting to drive again.
