Stay away from Nissan
 Extremely disappointed - first and last Nissan. Vehicle initially worked fine for first month than began to shake violently when going into EV mode.   Dealer "fixed" it but now it will not drive in EV Mode.  Been back to two separate dealers both of which say its normal.  First said it has "learned" my driving habits so it won't drive in EV the second claims EV does not work when the air conditioning is on (doesn't seem to work with it off) 6,000 miles on it and am ready to unload it.
