This vehicle has lost power at highway speeds 3 times now. Just driving along and it just starts slowing down on its own. Running 70mph and it just loses power and it slows to around 25mph. You mash the gas pedal to the floor and it has no effect, it will not increase speed. You pull over, shout the car off and restart and it runs fine again. You get no warning lights, no codes. This is a dangerous situation and should be looked into. Dealership said they have never heard of such a thing. I see someone else has filed a complaint with the same problem now maybe you will take a closer look at this very serious issue.

Driving long distances my car overheats, looses power going from 70 mph down to 40 mph in high speed traffic. I am forced to get off the highway and let it reset itself. It has always made a whining noise during acceleration, and the brakes have squeaked from day one. I have complained to Nissan several times and am always been given lame excuses. Now that my warranty is up they have a solution to my problems. New transmission or overheat converter to the tune of $1600. How convenient they have a solution not that my car is out of warranty!! they refuse to help me or fix my car unless I fork over the money. My car has had problems since I purchased it and there was never any resolve. I purchased an extended warranty as I do a lot of driving. My car was out of warranty 2,000 miles when they miraculously found a cause and solution for my problem.
