Infiniti M45 Sport Steering 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.
