Loss of power steering at low speeds. Initially occurred occasionally, but frequency has increased to the point where it now occurs almost daily. Prior to steering failure, I did notice a funny sound when the steering wheel was turned to far right or left. At first I thought this was just my car, but it would appear that it is a pretty widespread issue judging by the number of complaints lodged, which I am sure represent just a fraction of the owners who have experienced this issue. Given the serious safety issue involved, I am very surprised there has not been a recall since gm seems to be issuing recalls for much less serious issues.
I have already issued a complaint regarding this issue and continue to have issues with not being able to turn the vehicle in traffic. There have been over 60 complaints filed with the NHTSA regarding steering failure of this vehicle and similar platforms while in traffic. Gm has already been shown to fail to correct safety issues despite having knowledge of such (hence the current significant media coverage). There is a class action suit against gm in relation to this issue (the judge so far has ruled against gm to have the suit dismissed giving validity to the issue). I kindly request NHTSA re-evaluate this issue and initiate an investigation. I apologize for using this section to inquire but did not locate any other means of inquiry.
I have already had the steering rack replaced previously. . . Now, today, the steering pump is failing and needs to be replaced. . . This is a safety issue. . . I have notice a number of other Enclave owners experiencing this problem. There should be a recall on this item.
