One of my front windows had droopy weatherstripping inside & crooked area outside, so when I brought it in for other service items, I asked my dealer to fix it. They had to order parts. Next service visit, I pick up my car to find all weatherstripping on all windows replaced with different material than original. Next day, I notice it was buckled in some areas, so I brought it back a 3rd time & they fixed it while I waited. I noticed a big change in noise level right away, but I figured, it's March & very windy in NE, so I waited. Sure it was either the noise coming in from new weatherstripping or new engine loudness. Brought it in AGAIN (4th time) yesterday, & showed the service guy how it was different in the car in their showroom - it has the spongier material that my car started out with, that they replaced. Engine is fine, but now they agree that new material is rigid & may not absorb noise as well. They say the newer cars have the new, rigid material & they will "look into it". I am unhappy w/ the sound level in my car since they made a substantive repair w/o my consent that changes my satisfaction w/ the noise level. The noise level was one of the important reasons why I chose the car in the 1st place, so I am annoyed w/ the run around. They will probably tell me that Volvo changed the material (why?) & that I am better off. Any advice? Thanks!
