Biggest regret
 I purchased a 2014 Altima SL fully loaded brand new. My family has always driven Nissans and never had any outlandish problems with them. Within the first year i had issues with the fog lamps loosening therefore not functioning, the infotainment system rebooting while in use, drivers seat would slide back and forward at take off and when braking, a recall on the hood latch and a recall on the airbag sensors causing the car to think no one was in the passenger seat and turning off the passenger side airbags. Second year, A/C compressor was replaced and transmission completely failed on me and was replaced (under warranty, thank god). I'm approaching the end of the second year and the transmission may need replacing again. Electrical system is complete crud. And headlights flicker when i drive over the slightest bump. All lamps are loose. I especially regret paying an additional $1000 for the infotainment system because it often doesn't recognize that my phone is connected so i cant play my music or speak on the phone over the speakers. Rear view camera is great when im backing into parking spaces but it tends to glitch like a television using an antenna in the middle of a hurricane. Also, compared to the rear view camera in a 2009 Maxima, the picture quality is bad and almost useless after sundown. The '09 Maxima was very clear and vibrant in color both night and day. The rear view camera is used to determine whether there is someone in your blind spot and i can honestly say that it was wrong 40% of the time. It is also used to determine whether you're too close to the center lines so that it can alert you. This feature is called "Lane Departure Warning" and often didn't work either. A minor complaint would be that any time i have a passenger get out of the car, they have a hard time shutting the door on the first try. You practically have to slam them shut. The horn is weak, sucks if you're a honker like me haha. Navigation system always had a false ETA. For example, last night my ETA was 12:26 but the time was 12:53. Plus the navigation update is over $200+ just fyi. So if you live in a constantly developing area, like myself, the Navigation isn't going to recognize any of the new streets. Not going to drop $200+ every time a new business is put up. I'm actually currently looking to buy a 10 year old Acura. Update: I've now owned a 2006 Audi A6 Avant for 6 months and have had no issues like the ones listed above. Doesn't say much, as they're two totally different cars built almost a decade apart. But it does say a lot as far as preference goes. I'm enjoying my 11 year old station wagon more than I enjoyed my once brand new Nissan Altima.
