Car is extremely hard to turn/loss of power steering. Noticed that there was a recall on these vehicles but my vin was not included. Mechanic said Power steering rack is bad. This has been an ongoing issue with this car since purchased with only 70,000 miles - not sure why this VIN was not included in the recall? Car stock radio screen also has intermittent issues with displaying properly.
