 From jerking violently while shifting/CVT to shuddering until it shuts off while idling at stop lights, turning, behind school busses, etc., shutting off each time the car is placed in reverse or drive to completely disengaging while driving down the road/highway leading to coasting while the gas pedal and engine stop "talking" to each other, my car has progressively become a death trap.  This 2014 Altima appears to completely flummox the dealership's service folks.  They can't seem to fix it.  Corporate refuses to pay for or replace whatever is broken.  Oh, to top it off, the same Nissan dealership said it is only worth $9k for trade in.  Despite being very happy with the car for the first 18-months, this 4-time Nissan buyer is desperately searching for faith that this car's current issues are a fluke, can be fixed, and the car I worked so hard to buy will return to being the reliable, comfortable, and economic car I loved.
