Purchased the car about 8 months ago. It had 124,000 miles on it. I was on a local government auction site and saw it. I wasn't even looking for a car. I was actually looking for something else not car related. It had issues. Needed paint, starter, driver seat and some tlc. I checked for recalls and found that it had 2 recalls that needed to be done. Infiniti fixed them. While at the Infiniti Shop they saw that the gas gauge wasn't working properly. That was a $1000.00+ to repair. So after getting it painted, a new driver seat, starter and putting some tlc in it at an additional cost of $1000.00+ I finally think I have a great running car. Car has some get up to it.
This vehicle is reliable (at 90K miles) and still drives the same as when I drove it brand new off the lot. As an engineer, this car has all the technological gadgets one could want or need. Amazing driving performance (power - 340HP & 333 ft.-lb. of torque and handling) and style. I haven't had any issues except a recent gas gauge replacement by the manufacturer. This vehicle is incredible when I compare it to previous vehicles such as: 1991 M3 and Acura 3.0 CL.
I still believe this car is a Jeckyll and Hyde. We're still enjoying the power, but the transmission isn't very responsive and the manual mode is worthless. The seats are comfortable and have nice amenities, but the driver's seat squeaks now. We still love all the gadgets, but they are difficult to use. We've encountered more issues, but we do have 108K miles now. The exhaust manifold was changed under warranty. Now it's cracked again - poorly engineered. We still burn a quart every 1,000 miles (108 quarts so far!) Tire wear is phenomenal. The originals ran 28K miles. The second set were Essenzia and were just changed. The new Hankook Ventas don't feel very good on the car.
Obviously all used cars now and if you see one on the lot steer clear and let it rot on the lot. We have owned one now for about 4 years and up til recently have been some what satisfied. It has about 80K on it and everything is falling apart. Like previous poster gas guage is unreliable and it has been in the shop waiting for a part for over a week now. The whole instrument cluster has to be replaced!! A big rig has a tighter turning radius. Interior lights have been replaced a few times too and rarely work correctly. Infinities are not built to last.
I just purchased a 2003 M45 with 70,000 miles on it. I've always liked the style and the power is great. Its a great used car bargain I'm just glad I never bought it new. The quality is below luxury in my book. I also have a Lexus the quality of the material and finish is top notch. The Infiniti not so much trunk struts don't work, center arm rest is cheap and feels loose, sunroof liner coming apart, fuel guage not reading correctly (recalled ), engine doesn't start up on first try sometimes, and airbag light is on. Alot of issues for a car with 70k, but I've always wanted one and I dont regret buying it for $7500. Especially since its not a daily driver. I have a Gs300 and Yaris for that.
