 I bought an FX 35, 2006. Drove great for 6 months and then had an issue with the rack and pinion. Since then there has been a shake in the car around 60 to 70 miles. The steering wheel shakes consistently and the dealership cannot seem to fix it. I have taken it in four times and they keep saying it is normal for the car. Normal for 40K car to shake at 60 miles an hours. Very disappointed in Infiniti. Will never buy an Infiniti again.
