  Save money, buy lexus - 2006 Infiniti M45
  By CHUCK - October 6 - 11:50 am

  A little harsh ride and quite noisy for a $50k plus vehicle. This clunker has been in the shop almost as many days as its been on the road. "Smart" cruise control shuts off if headed into the sun. Lane departure system beeps when Im in the middle of the lane. Brake cylinder needed to be repaired, door seal deteriorated, AND I ONLY HAVE 7,000 MILES ON IT!!! Looks great but Lexus makes a much better vehicle in the ES330 and GS series and the Lexus ownership experience is far superior (I also have a Lexus SC 430). Dealership treats me like I bought a Yugo. I have already traded this piece of crap after only 6 months on an ES 330.

  Great car so far. Pretty fast, handles like a dream. Not so sure about the redundant controls for audio, climate etc, But overall a great car.

  Love my new M45 - 2006 Infiniti M45
  By John - June 30 - 7:03 am

  I have owned 6 Q45s and loved them all but this one is the best car yet. Very sporty, roomy, fast, luxorious as well as quiet and sound. I am very happy with it after a week or ownership.

  Great Car - 2006 Infiniti M45
  By cst - May 1 - 5:23 pm

  This is a remarkable car. I cant get over how well the Sport stick through corners. The active steering is a real bonus for "spirited" driving. Everything works well, although the lane departure warning can be annoying.

  By Johnhw2 - April 12 - 6:20 pm

  Best Infiniti product Ive owned after several Q45s. This car rocks its comfy, roomy and fast with great handling. Love the aluminum dash trim and the black exterior with the stone interior. Great combo and love the wheels on the sport M45 as well

  Acceleration blocked - 2006 Infiniti M45
  By Bob Ringgenberrg - March 23 - 11:13 pm

  Rarely when attempting to accelerate for a stop or slow speed, it gets stuck at 2,000 rpm and 20 mph and will not advance . You must take your foot off the accelerator and reapply slowly, Same with the manual mode. Can be dangerus when changing lanes in heavy traffic. To dealer 3 timers, they say they can not replicate this and it is fine. It is not fine, did this from day one. Some one said a software problem may exist as it is 1st generation software. I think I will trade in on a G35. I really like the M45 but but every time you want to get up and go you hold your breath because there is a chance it wont. Any help appreciated.

  Horse power and torque is incredible! - 2006 Infiniti M45
  By LeonC626 - February 18 - 12:30 pm

  I originally had my sights on the QX56 but after test driving the M35 and M45, I decided to go with something sporty. The initial test drive with M35 wasnt quite satisfying, so I decided to test out the M45. The V8 on the 45 version has a great compromise on the bulkiness of the sedan. The car takes off like a rocket. The thrill on speed is just one of the best features, the stability is probably the second biggest accomplishment for this car. Body roll is minimal when serving through the lanes in high speed on the freeway. The manual shifting is precise and quick. The only recommendation I have for this car is a six-speed auto gear box insteaf of five and a small lift on the rear facia.

  Great value, still not quite first tier - 2006 Infiniti M45
  By Paul Rogers - October 28 - 3:03 am

  I have come to the M45 after 12 years of owning much higher-end luxry performance cars: Mercedes SL55, Jaguar XJR, Acura NSX. The M45 won me over with the only interior design comparable to the first-tier cars, and very reasonable performance for a 4 door sedan. Exterior design is uninspiring, sharing far too much with the Nissan Altima and Maxima. Highs: interior design, wheels, ride comfort, seating room, performance capability, value. Mediums: steering response, exterior styling, exterior fit and finish, paint quality, audio Lows: interior fit and finish (relative to class); buggy XM radio implementation; rear shade is $5000 option (because it is bundled with rear video screen)
