I had my gear replaced in the steering unit on the ATS-V. The service involved 2 full days and a part of another. They had to drop some of the suspension to access the gear. They did an alignment and provided me a great service loaner XT5 fully loaded. Beautiful car. I told them to check the fluid in the battery and the battery needed replacement under warranty. The car drives perfectly, just like it previously did. It's interesting that GM sent me a bulletin in the mail and stated they didn't know when the part would be available. They haven't contacted me to say the parts are available. I'm glad I reached out to my local dealer about this. If you haven't received a recall notice, it would be wise to contact your local dealer about this. If the part fails, the steering will be extremely heavy and may cause you to lose control; thus causing an accident. I would like to know if anybody else has had this done.
