You are in the Buick Rendezvous Forum. Your Hosts are steve_ & tidester
I have a 06 RDV. I love this vehicle. The only problem is that it makes a lot of road noise. Or I think that's what it is. I've also thought it could be wind noise. My sister owns a Trailblazer and says hers does the same thing so I'm thinking that maybe it's the open interior. I took it in and they said it was incorrect tire pressure. After fixing that it still made the noise. It is a low, base sound that comes from the back of the vehicle. The sound is louder if there is weight in the back. Going over bridges is the loudest. It just seems to echo inside it. The dealer said the RDV shouldn't make noise. They say they are going to spray insulation in it to try to reduce the noise. I am taking it to another dealer and getting their take on it. I think I've stumped them and they are blowing me off. Has anyone else experienced this problem?

Replying to: tidester (Jul 11, 2007 6:14 pm) - Wheel bearings starting to let go. If a "humming" type sound, then it could be wheel bearings. Yes, even new vehicles can have "fluke" wheel bearing problems. - Too Knobby Tires. If you have aggressive tread tires, they will make a humming noise as well. That's why snow tires design treads hum much more then seasonal tread design tires. - AC clutch is worn or fan belt idler tensioner bearings are going. These things can make a humming noise but most of the time, they also have a high squeek noise (between the humming up/downs). - Leaky exhaust pipe. Especially if the sound is from under the RDV, then echos back at you, from the side of bridge walls. Man, talk about sourround sound. LOL!!! - Front Wheel drive transmissions make higher humming noise when compared to RWD / mid mounted transmissions. The reason is, their natural humming sound is being pushed from the front, into the cabin area. Compared to a mid-mount tranny and it sound is being pushed to the back of the vehicle (behind the driver). Especially when traveling high speeds. This is why rear passengers hear your vehicle differently compared to someone sitting in the front seat. - Front wheel drive CV Joints have higher humming sounds as well. FWD CV Joints tend to hum more - compared to RWD CV Joints in their single drive shaft. Again, sound is behind the driver compared to front CV Joint sound that is pushed into the firewall, then echos onto the driver. As a suggestion, do focus on the wheel bearings (especially the front wheel bearings), front CV Joints and wheel rubber tread aggesiveness. This items usually create 95% too much noise. Especially one's tire rubber design at high ground speed. If wondering, I have a '03 RDV (my wife's run-about vehicle) and at high ground speed, its front wheels, CV Joints or something in the front hums much louder compared to other FWD mini-SUVs of simular design. Took a different '03 RDV for a test spin and it made the same level of sound. Thus, I figure these RDVs have more front end noise - when compared to others. Perhaps your '05 RDV has "too much" natural noise as well? You might want to take other '05 RDVs for a test spin - to compare its sound against your '05 RDV sounds. Who knows, perhaps your '05 is normal. (sort of speaking) Hope this helps... .

Is the kit referred to in an earlier post to rectify the noise I am hearing around 2000RPM up to around 2500RPM? It is an annoying rumble that resonates through the whole vehicle. I was going to have my muffler replaced, but if a kit exists, how much is the typical cost for parts and labour?
