I was watching yesterday the hearings about the cobalt ignition switch . I do not care much about this specific part.. I was just listening to learn how GM operates internally . My feeling is after an hour plus of the congressional questions to her she is incompetent to RUN GM. It appeared that the political reps knew more about this switch failure than she did . I find that unacceptable. She was aware of this issue 31 jan 2014. now it is 1 apr 2014, no excuse. The problem with all of these component failures and GM hiding these failures is not with just this part. sure some people died and this could have been avoided if GM did the fix 10 years ago . this it is stated would have cost 57 cents more to manufacture and that added cost is was not acceptable at the time GM made this decision. GM should not use the same part number on a change in the part , due to the part being defective and or not making the GM engineered spec.the part number should have a REV-A after the number with one change and if more changes are made B C D E etc.... GM should not use any part / manufactured component that does not meet the designed spec. GM should make available all TSB about an owners vehicle to the owner. this can be done by having a web site dedicated to owners where they type in their VIN number and all the TSB for their vehicle is displayed in its entirety. hopefully these hearings will change how these profit over safety corporations operate. the people that got killed due to an added 57 cent part cost did not die for nothing . what are your thoughts ?
