- Buick Ownership
I'd would suggest that all 2006 Rendezvous owners inspect your fuel supply line underneath the car. Right around the driver's seat, toward the middle of the car, there are heat sleeves on the fuel supply line that had severe rust to the point where I had a leak occur. The rest of the line looked fine. I am assuming the sleeves were the cause due to moisture being trapped. I have a hard time believing my issue was isolated. Do yourself a favor and check this line as soon as possible. I'm not sure about other years of the Rendezvous but I'm assuming the setup would have been similar in models close to 2006. Is this an issue on your Rendezvous?
