I've owned this car for 63k miles now. It's been incredibly reliable, and fun to drive. I Love everything about it, except the gas mileage, which has averaged 17.9mpg. With the manual transmission, I do drive it HARD though. But it's time for some true American Muscle so I'll be selling it for a Challenger SRT8,with a manual transmission of course.
I bought my 2006 G35 Coupe automatic in 10/2006. I have had one accident, some small fender benders. Overall the performance has been great. The good: The car handles well, superb acceleration and braking. The automatic transmission has been reliable, although a little bumpy between 1st and 2nd. The styling of course is unparalleled. The interior technology package has worked well - the navigation is spot-on - a little awkward to use with the joystick inputs, but not bad for 2006. The Bluetooth has never failed though 4 iPhones. It connects every time, and the voice input is about 95% accurate. The audio system - CD changer, speakers work perfectly to this day. Electronic seat warmer and adjusters have not failed.
The bad: Interior components have been cheap. There have been a few gimpy components. The removable cupholder - very cheap and the spring broke after about 2 years. The DC socket has failed about 3-4 times. Driver window motor had to be replaced after 125k miles. The tire pressure sensor had to be replaced after 90k miles. After 80k miles, leather covering the door panels are starting to peel off, and after 120k miles, the leather on the side panels in the back have completely peeled off (and nobody ever sits back there).
The ugly: Tires - need to be replaced every 20-30k.
Overall I like this car. Performance is very reliable. I have not had many huge problems with the vehicle, however there are numerous small fixes for the car. The car is very tough on the tires (and I have a stock 18" wheels).
I have a 2006 Infiniti G35 that has 53k miles on it. All services have been performed though not through the dealer. My supplemental airbag light came on at just under 53k miles.The dealership quoted $2700.00 to repair. I almost fainted! Come to find out that ONLY the dealership can fix this as they do not sell the parts. RIP OFF! The car has never been in an accident and air bag has never deployed. Shame on Infiniti!
Get up and go.. look and style of car.
The air bag issue seems to occur with frequency for the Nissan 350 as well as the G35 in years 2005 to 2009. Buyer Beware!
Bought it with 50k miles 4.5 years ago and now 126k and still runs like it did when I bought it. Basic maintenance only. This is a great car!Looking at all the negative comments on 3-series maintenance costs I'm glad I went infinity! Gas mileage is so-so but most performance cars are.
Update: now at 150k and had to replace radiator and steering rack has a small leak. Not bad for a 10 year old car. I'd still buy it again in a heartbeat. Great car!
