2007 Nissan Versa Hatchback 1.8 SL 4dr Hatchback (1.8L 4cyl CVT)
Nissan Can't Determine Cause of Problem
 I've owned my Versa for almost 1 1/2 years and my problems began almost immediately.  During cold weather the car will occasionally start in safe mode where no gas goes to the engine.  The car will only drive 20 KM/hr. Another problem is that the engine will begin to race and rev higher than normal and the car will speed up on its own.  I love so much about the car but could really do without the problems no one seems able to fix.
