2003 Nissan 350Z has constant problem with front suspension which causes tire noise, improper tire wear, and premature replacement of tires. Nissan is unable to align the car or fix the vehicle in any way that avoids the problem long-term. Replacing or rotating tires does not solve the problem, neither do alignments or balancing. Dealer gives the customer difficulties when servicing the suspension under the factory warranty, and is not addressing the issue with the consumer, safety, or customer service in mind.

Suspension in car makes vehicle ride rougher than usual, making tires wear uneven.

Suspension on my 2003 Nissan 350Z. There appears to be a design flaw that is causing cupping on the front tires. The dealer has remounted the tires on opposite wheels, rebalanced, and realigned the front end at aproximately 6700 miles (as per manufacturer) the cupping has reocurred at 8700 miles.

I own a 2003 Nissan 350Z, enthusiast model. It is only 6 months old with 7500 miles, and the front tires (and to a lesser degree, the rears as well) have begun to feather. Feathering is a type of uneven tire wear that causes very unpleasant road noise when driving and also sacrifices the life, performance, and reliability of the tire. Feathering is caused by defective suspension design -- it is not a problem with tire design. Experts note that feathering will happen when the suspension exhibits excessive toe-in.Nissan has received multiple complaints regarding this issue from fellow members of a 350Z forum of which I am a part, but it will not issue a permanent fix for it. (they have issued an immediate short-term fix, but the problem recurs in 2,000-3,000 miles after this fix. No permanent fix is available and Nissan is just delaying the permanent repairs until warranty runs out with this temporary fix.) if you will, please look at my350Z.com and search for "feathering" and you will see that a good majority of 2003 model owners are experiencing feathering problems. My car is completely to factory specification, and at this rate of tire wear, I am afraid the tires will have to replaced in less than 1,000 more miles. I am worried that fellow 350Z owners that are unaware of this serious problem will be risking their lives, if they expect the tires to last 20,000 miles (the average), but they realize that at 20,000 miles they've been running on nothing but a bald set of tires. NHTSA, this is a very serious safety problem that needs immediate action. Tires are the only things holding the cars to the road, and the tires on the 350Z are wearing out at unbelievably fast rates. Unsuspecting people will be injured because of this problem that Nissan is aware of, but will not bother to fix. Nissan must be forced to fix this issue, as they have simply been ignoring this.

I purchased a new Nissan 350Z in may of 2003. At approximately 7000 miles I noticed some strange noises coming from the tires. After inspection I realized there was very uneven tire wear on the front tires. I then began doing research as to why this was happening only to find out that nearly every new 350Z is experiencing this problem. Nissan's "fix" is to rotate the tires but anyone with a brain can figure out this does not resolve the problem, only gets rid of the noise for a few thousand miles. The wear on my tires was so bad they could not rotate them and were forced to replace the tires. After tire replacement, I noticed an immediate change in handling. I believe the strange tire wear is causing less than adequate performance/handling/traction and could eventually become dangerous if left unfixed. There are many speculations as to why this is occurring but all 350Z owners tend to agree that the front suspension on the vehicle is causing the problems. Nissan is trying to hide this issue from the broad public but more and more people are becoming aware of this.

I took my car (2003 Nissan 350Z) to my Nissan dealership on or around September 25 to have the Nissan tire feathering/cupping/road noise technical service bulletin performed due to excessive road noise when braking, and visibly uneven wear on the inside tread on all four (4) tires. Nissan's "fix" for this issues is to dismount the tires from the wheels and switch the tires left to right (because they are directional tires and cannot be "traditionally" rotated). Feathering/cupping came back less than 2000 miles later. I have an appointment scheduled for 10/16/2003 to have the issue looked at again, and also filed a report with Nissan North America. Tons of other Nissan 350Z owners are having the same issue. This is not a fix for the huge problem Nissan has with this car, and we need a final resolution! replacing the tires with new oem or other branded tires does not seem to rectify the issue either. I feel as though my safety, and the safety of others is jeopardized. The suspension or some other mechanical aspect is clearly not engineered correctly.

I am concerned about my Nissan 350Z suspension/tires. I have been reading a lot of bulletin board entries on www.my350Z.com and www.zcar.com about vehicles manufactured before Dec. Of 2002. I also visited the Nissan website and see that there is a tech bulletin posted about the wear on the tires. There appears to be an issue with the suspension set up on the 350Z that is resulting in excessive wear on the tires or feathering. There are a lot of pictures on the www.my350Z.com website of actual tires. The feathering seems to begin anywhere from 5000 to 10000 miles.
