Regular driving. I went to park car and could not take out of gear only able to put the car in neutral and leave key in ignition . The car rolled into and was stopped by curbing, thankfully, before rolling into a busy road. The shift lock solenoid on Nissan Altima locked up. The shift lock solenoid and shift lock control module were replaced and old parts kept by dealer.
