Transmission failure at 102,000 miles.
Motor mounts had to be replaced twice by the dealer within 10k miles.
Front rotors were replaced after 1 year of ownership.
Radio/display panel went out in less than 2 years.
Sunroof opens mysteriously, and to this day, the dealer still can't explain why.
My wife's 04 Maxima transmission went into what the dealer called "Safe Mode", where it stuck in 3rd gear, and couldn't shift up or down.
I found this site, and was concerned the dealer would jerk me around, like it appears they've done so many of you. So I had a family friend, who owns a transmission shop, run the diagnostic. He was familiar with the Nissan transmission, including its issues, but found the problem to be 1 of 3 "positioning sensors". The diagnostic won't tell you which sensor failed, so you need to replace all 3 to be safe.
Now here's the good news, unless you take it to the dealer, the sensors cost less than $60.00, and I was back on the road for under $300.
