Problems with CVT
 Don't buy Altima with CVT if it does not have ABS. The issue occurs at speeds over 45 mph. If you slam breaks so they lockup until car comes to complete stop transmission locks up and throttle is stuck for up to a minute at a time. Nissan refused to correct this issue saying that this is intentional to protect transmission. It happened to me at intersection and I was able to duplicate this every time at will. I have traded my car and bought a new one.
