Buick lacrosse review

I don't know how well those guys have road tested the 2011 lacrosse v6 with the 18" wheels before they put it into production but I can tell you, they did not do a good job. I am one of the unlucky owners of the 2011 Lacrosse and I am completely disappointed with this, supposed, luxury vehicle. The main culprit is the terrible road noise coming from wheels. On any surface that is slightly rougher than completely smooth asphalt, the noise is very excessive. We compared the road noise with a 2002 very used Nissan Altima and found noise in the lacrosse to be much worse. Especially on any metal junctions, such as the bridges and overpasses, and on rough cement or asphalt surfaces, the tires sound as though someone was hitting the vehicle with a hammer on the metal joints and there is that overwhelming low frequency noise like a plane flying in close proximity on gravel and other rough surfaces. The tire noise is the same on all the 2011 Lacrosses with the 18” rims. The other problem is the exhaust. The two mufflers sound like a boom box at very low rpm's. We plugged one up to test where the noise comes from and found the car 50% quieter. Apparently the other muffler is just for the looks and does not serve the purpose that it was designed for; that is, muffling the noise. I did not have a chance to see if you did anything about the tire noise on the 2012 models, but I did see that they did something with the exhaust system.
