I've got a 2006 (purchased Sep 05), M45 Sport with 16,500 miles. Original tires (although I've order new ones) and a major steering pressure issue. I've had the issue for over a year. The car seems to feel loose and sloppy on some days, tight and responsive on other days. When it's tight, it's a hell of a great ride. When it's loose, it's all over the road and very difficult to control. Some days I will exit at high-speed off-ramp and the steering gets "too tight" to where it is actually difficult to turn in, other times it's so loose that I have to back off to prevent over-steering the car into a spin. Although very noticeable to me, the dealer "cannot duplicate" the symptoms. I've documented the sensitivity every day for 4 months now and have been battling the dealership on a cause of this. Has anyone experienced this variance in steering pressure? Any suggestions? Also, on occasion, I get a very aggressive vibration in the steering column at about 74-80MPH. Not road vibration, clearly it's steering vibration. Tires have been balanced several times and alignment was performed too. They've already had to re-align the car, they replace the rack and pinion (though they never told me why) and they've found a bent wheel sensor which they need to replace. I've got a long list of issues with this vehicle, most of which were resolved, but this one lingers. |

Get used to the dealer telling you that they cannot duplicate the problem. From what I have been told, the used parts are sent back to infiniti to make sure that the replaced parts are actually defective. I have had some issues with my M45 that have not been repaired for over a year with multiple complaints to my dealer (this is why I just ordered a new BMW 750). On your steering issue check your front tire pressure, to see if they are the same on each side. (I did have the same issue when my front tires were worn and it went away when they were replaced.)

Replying to: buster6 (Mar 21, 2007 7:41 pm) I don't doubt the problems you've had. Individual cars from any manufacturer can be a nightmare. However, the reliability of the M is higher than average and owner satisfaction is much higher than average according to Consumer Reports. For the BMW 7 Series reliability is much worse than average and owner satisfaction is just average. I hope you're not jumping out of the frying pan and into the fire!

Replying to: arlingtonva1 (Mar 19, 2008 7:21 pm) Also replaced the Bridgestones with Michelin Pilot Sport All Seasons- the only A/S tire made in the oddball 245/40/19" size...highly recommended, tremendous improvement in ride and noise. |

I have the exact same problems as described by "arlingtonva1". Mine is a 2006 M45, Sport. At this point it has 43k miles on it (I commute a allot) and I have noticed this issue for quite some time. All tires have been replaced, and I have had multiple alignments etc. And much like other people here - the dealer "can not" duplicate my issue. Mine seems to be jerky at high and low speeds given the road condition, groovage etc. Did your dealer replace the steering rack free of charge? Or did you have to come out of pocket - I really don't want to spend a ton of money to fix something that I feel should not be a problem in this level of a car - but at this point, I am willing to just to be able to actually enjoy driving it again.

Replying to: shanster01 (Sep 01, 2008 12:40 pm) This is a real safety problem...and infiniti is trying to resist a full recall. If you can't reproduce the problem with him, ask him to schedule a ride with the infiniti (corporate) service rep the next time they are in town....that may be enough to trigger the free fix. This is a serious problem...they will repair for free...and they know about the problem.
