Is anyone aware of this model Nissan losing power after/during a long drive? It has happened 3 times in 3 months. I took it to Nissan and no codes showed up. They put something on my car that would read the code if it happened again, but it still showed nothing. The mechanic at Nissan says that it is a known issue with the v6 Altima, but there’s never been a recall. Does this sound right?
