This is the first time I have ever joined an online dicussion and posted anything but I dont know what to do. I purchased a brand new GX 470 2008, the first week of November. I had a GS before that and never really had any problems. This car has had problem after problem. The first problem was the "clunking thumping" noise when I stepped on the brake. When I brought the car in, they hapily changed the driveshaft for me ( even though I feel that a new car should NOT need a driveshaft replaced, especially in this price range). Then I kept feeling my engine rattling and my car shaking on a regualr basis. I would read the forum and just assumed it was normal. Then one day, my check engine light went on, my VSC light went on, my skid light went on and another malfunctioning light. I brought it into the dealership and they told me it was electrical and now its fine. This problem happened once again and I refused to drive the car home since my brakes would pump back at me and all the malfunctioning lights went on again. They again fixed and told me it wouldnt happen again. Low and behold, yesterday morning, the same problem occured. My RPM's were over 2 while I was in park, my brakes pumped back at me, my malfunctioning lights went on and again, I had to be towed to the dealer. I am convinced this car is a lemon and I refuse to drive it again. Has anyone had the same or similar experience or have any advice for me???
