There appears to be a large amount of cobalt and Hhr owners with complaints about suspension clunking noises. Research shows there is an issue with the stabilizer bar parts and also the intermediate steering shaft. These problems occur at many intervals of mileage ranging from 10,000 miles and up. Gm has since sued the manufacturer of the intermediate steering shaft for those replaced under warranty equaling $30mil. I am unlucky as my vehicle was out of warranty (3yr/36000 miles) and could not get any of my suspension and steering problems fixed by a known issue from gm. They have stated that the intermediate steering shaft is not a safety concern. Now, if a part that is vital in connecting the steering column to the rack and pinion system is not a safety concern, then I believe gm executives are more concerned with cost of doing the right thing than safety of their customers. These are parts that keep a vehicle from flipping over during sharp turns at highway speeds and that keep the car traveling in the direction the operator determines using the steering wheel. After replacing the parts to correct my issues, the problem has re-occurred. The parts were not changed so even after "fixing" it, it would eventually return.
