Re: Thumping/Clunking Noise, anyone?
I have the same problem with my 2008 with 18,000 miles, I have taken the car to the dealership 6 times for this issue the first time last April, when I got a smile and the we can't duplicate the problem. Only when I went in armed with about 75 pages from this site and the acadia site concerning this and 4 trips to the dealership concerning this did we get a response. I have also contacted Saturn and they have opened a file, my Saturn rep that is helping with my file is located in South America! (?) I had the service manager ride with me for two days and the car finally made the noise, they had someone else drive the car and they felt the "bump/hesitation" in the steering and decided to look into the steering column. They did find an issue and replaced the column. However I picked up the car at lunch today less than 20 miles after the fix the car did it again, this time not while turning left, but going straight. I know what the ABS self test sounds/feels like and this is a completely different issue.
This almost feels like the car is skipping and the tire is hitting or rubbing something under the car, when it does happen it is at low speeds (under 30) and turning left (except now). The steering becomes hard to turn and it makes that loud thump thump thump thump noise and the car skips. Since they have replaced the column any other suggestions out there?
I am sure they are going to be thrilled in the morning when I call to give them the great news. I am also calling my South American Saturn rep and fill him in as well. He first told me that he could not find any info of steering problems, I informed him I had plenty.
I would suggest if you are having this issue take your car in, if nothing is done to fix the problem, call Saturn customer care and get a case number. I believe this could be a major safety concern for all of us and it needs to be reported to your service department, local dealership, and Saturn customer service.
