I did a search on this but need more info please

Have a G35X. Don't know if it's just me or if there is a real problem here.

Have 900 miles on the car. Had it in the shop at 600 miles for bumpy ride on highway between 60 and 75 mph. Feels like I'm going over small continuous bumps. Please keep in mind that I traded a 350ZR for this and my Z had a smoother ride on the highway than the G35X.

The tech said that two of my tires had excessive road force and he replaced them with new tires and rebalanced the other two. (Bridgestone Turanzas) Took the car out for a ride and seemed to ride better at first but now I'm still getting what feels like a continuous bumpy ride on the highway. I should say that I live in Massachusetts and the highways here are not the best.

I expected the ride to to somewhat hard because of the suspension, but this seems excessive. The service department seems more that willing to please. I'm waiting to put more miles on the car to give it a proper chance to break-in.

Any advice would be appreciated.

 

It's not you, that's for sure. Hopefully the dealer can remedy the problem. Someone else was complaining of a balancing problem, but they had Firestone Wide Oval tires. They ended up getting it balanced at a Nissan dealer.
