We purchased the Nissan becuse of the safety system's and when we took it back to the dealer for oil changes in the first and second year of owning the new car we experienced a warning light coming on for the front radar. We asked Bomareno Nissan of St. Louis to investigate when he had the can in for service but they always said everything is ok. But the first time we took it back after the warranty time ran out but not the malage the dealership stated the front radar has failed and the to change it it would cost $1,700. And to make matters worse he state this happens a lot. I belive Nissan has a problem with their radar. I have sent this message to St Louis Bomareno Nissan but no reply.
