Upon entering a parking space,my 2013 Subaru Outback went from idle to full acceleration,hitting a parked,unoccupied truck. Braking had no effect on the car,the air bag did not deploy,and the car did not decelerate until I was able to engage Park-within a few seconds it resumed the idle. The police made a report,car was taken to wrecking yard,and is now at repair facility for possible repair. There were no prior warnings or messages. I was unaware of a safety issue with Subaru and when I contacted my local dealer,I was told they were unaware of any issues. I then did research online and found numerous problems.
