I experienced "hard starts" "engine run on" and "rough idle" for approximately three to five months. The problem was diagnosed as a leaking fuel injector. The gm dealer garage informed me that they "see this all the time with gm products" and that the leaking fuel presented a significant fire hazard. The garage stated that while gm will repair fuel injectors with california emissions, they will not do so with federal emissions. Gm has been no help and told me I had no recourse to recover the money paid to replace the fuel injector (appoximately $700). It seems to me if the problem is common, presents a safety hazard, and has been the subject of an acknowledged problem, some investigation into this issue should take place..
