Steering Rack And Pinion Problems of Infiniti M35

Driving with cruise control on, 70mph zone, slight downhill speed of 72mph. New rear tires, very good condition front tires, 1 day old 4 wheel alignment, concrete highway surface in sunny dry conditions, approximate outside temp 65. Vehicle and steering wheel jerked to the right with steering wheel displacing approximately 30-45 degrees from center to the right, followed by a jerk and displacement to the left of approximately 30-45 degrees to the left and repeated to the right and left again. . . Car was uncontrollable. . . Reduced speed, killed cruise control, lightly applied brakes. Car became more controllable as speed was reduced. Major auto repair location and ase certified mechanics diagnosed as problem with rack and pinion, possibly "a stuck valve" causing excessive steering inputs to be allowed at higher speeds than normal.

The contact owns a 2006 M35 Infiniti. The contact stated the steering wheel began to jerk when she made wide turns to the left and right. The vehicle was taken to a mechanic who stated the failure was located within the rack and pinion. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 80,000. The approximate current mileage was 86,000.

Vehicle started shifting to right of the road. Paid for wheel alignment. Purchased set of new tires at around 115000 miles. Now at 130,000 miles dealer tells me that my rack and pinion is leaking and could result in sudden inoperable vehicle. The part can only be purchased from Infiniti and approximate cost is around $1450. 00 plus $500-$700 to install!!.

The vehicle groging noise when making a right turn likew there is something rubbing the rack/pinion which can be felt in the steering wheel. Its really bad in the morning when the car is cold but even when the cars warm at times its really bad.

My 2006 Infiniti M35x will unexpectedly wonder across lanes. Sometimes it goes straight then suddenly it will veer right or left. I have taken it to the dealer and verified the alignment was correct. Dealer told me try new tires, which I did. Nothing corrects the issue. I have found many many discussions on this issue and it appears a faulty rack and pinion but the company will not replace it unless you still have warranty left. This is a major safety issue and almost resulted in an accident many times. My wife now refuses to drive the car as it pulled her off the road.
