 I have had repeat visits to the dealer to address the problem of hesitation when accelerating, which I am told the service department cannot duplicate, and they cannot fix what they can't find.I have had my car for 26 months and hate driving it on the highways.When I travel to San Diego to visit grandchildren, I rent a vehicle.Am I the only Altima owner experiencing this problem?Now, the transmission is jerking when driving at low speeds.So, the vehicle is back at the dealer's shop once again.What a horrible Nissan product!
