The car engine cuts off / stalls while driving. This has happened multiple times. When driving on highway, the engine stops running, the car loses all power, and it is very difficult to restart the car. I had the car inspected and the local mechanic stated the crankshaft sensor/ camshaft censor is not working properly and he believed this was on recall, but Infiniti stated that my car is not covered. This is extremely dangerous - call stalls in the middle of the road with no power at all.
