#171 of 224 Need help to improve on rough ride
Aug 07, 2007 (12:50 pm)
I have the 2007 Sentra for about 7 months. I'm satisfied with with everything EXEPT the rough ride. I didn't test drive it thorough enough, like going to roads with rough surface. Soon I found out the the ride on rough road surface is very uncomfortable. Even my passengers comments that the ride is too rough. Then I found out that instead of having rear independent suspension, the 2007 Sentra has torsion beam suspension which is cheaper and not as good in dampening vibration due to rough road surface. Furthermore, the car came with Bridgestone tires which people say are made by Firestone.
I had a 98 Toyota Corolla before with Firestone tires and the same rough ride problem. After one of the Firestone tires burst on a pothole, I changed all four tires into a medium price brand and the ride became so smooth that it felt like the Corolla had a new and better suspension.
I asked the Nissan dealer if some 2007 Sentra are sold with tires other than Bridgestone. They told me they are sold with Bridgestone tires only.
I am not sure if changing the Bridgestone tires in my car will improve the smoothness of the ride like changing the Firestone tires before.
I will appreciate it if any owners of 2007 Sentra have answers for the following questions:
1/Did any owners buy the car with tires of another brand that is not Bridgestone or Firestone?
2/ Do any owners experience the same rough ride problem and what is brand name of their tires?
3/ Do any owners have acceptable smooth ride and what is the brand name of their tires?

Is remote keyless entry something that can be installed after market on a 2.O 2007 Sentra?

My 2.0. S has the Bridgestone tires and the ride is great at 32 PSI. Anything over 38 is too much and causes a harsher ride.

Thank you very much for your advice. I checked the tire pressure and found that it was 36 psi for all four tires instead of the 33 recommended by the manual and 32 recommmended by you. The original pressure could have been even higher seven moths ago.I wonder why the Nissan dealership did not follow the instuction from its own manual.
Anyway I reduced the pressure to 33 psi and found that there is significant improvement on rough road surface. I am going to reduce the pressure to 32 to see if there is further improvement. But I cannot do it right away as the tire pressure has increased to 36 psi when the tires are still hot from the drive.
The Nissan dealerships should pay attention to details in their garage services. Besides the inaccurate tire pressure, they also forgot to tighten the cap of the coolent tank in my car during scheduled maintenance, which would lead to the engine become overheated when the hot coolent evaporates. The 2007 Nissan Sentra is a good quality car, the dealership should prevent mistakes that make people think the car is bad.

I agree with you.
When buying a car, the dealership should make sure that the car is delivered with the tires inflated to the recommended pressure.
Now, if you are going to travel in hot weather, with a full load and at sustained speeds of 70 mph or higher, by all means increase the tire pressure to at least 36 PSI.
The higher the pressure, the higher load the tire can carry (do not exceed maximum pressure as printed on the tire sidewall).

32 psi does give a smoother ride.
Thank you for the additional information.

Question about this: if the transmission's gears are replaced by a belt, is Nissan not engineering the transmission to be not as durable by designing something that will eventually break? Like the timing belt in every car except Toyota? I'm a little concerned and confused that they would create a new maintenance issue.

Its not a belt in that sense, as its made of a much stronger material. Not sure what exactly as its not just steel either. some kind of alloy I'd guess. so no, the belt breaking isn't an issue. At least not any sooner than any other transmisson would need rebuilt or replaced. If fact, thats what kept cvt's out of larger cars for so long. the engineers couldn't come up with a belt strong enough to withstand the torque and HP of larger more powerfull vehicles.

Excellent, thank you. You know the car makers made a serious mistake replacing the timing chain with a belt, and some, like Toyota, have gone back to the chain. If belt-driven transmissions were in our future, I would give up on automatics altogether!
Thanks for sharing what you know!

I found this webpage and according to waht they advertise you can get an aftermarket beeper for the locks in a 2007 Sentra 2.0. I have not ordered it yet, but I am seriously thinking about giving it a try. I also found the same beeper they sell ib Ebay for around $20.00.
