 Like many here, this was my first luxury car purchase. I purchased it in September 2014. My first trip a week later, it started stuttering and jerking and jumping upon acceleration. I took it back to the dealer every week for months. Each time they replaced something significant, like the transmission. I think I had 3 or 4 new transmissions. At one point, they replaced the engine. This car was a disaster. In the 6 months I owned it, the dealer had it more often than me and put more miles on it than I did. They called at one point and offered me $1000 to shut up and dismiss my claims. Um, no. After dealing with it for 5 months, the person at Nissan Corporate said she didn't realize my transmission had been replaced so many times. So they bought it back. But charged me for all the miles, most of which had been the result of the dealer driving it or going back and forth to the dealer. Then I got a notice prior to the completion of the buy back (and after they had already told me what they would give me for it) that I should make a payment since the buy back wasn't final.  I financed through NISSAN!!. I made the payment anyway. And sure enough, when I got my check, it was for the original amount and didn't include the payback of my payment. So they tried to pocket that. I appealed it and it took a month or so to get that back. The only people that impressed me about Infiniti were the service people, who REALLY tried. Everyone else was horrible, from the sell to the buy back.
