Engine check light on intermittently. SUV accelelerate slowly, rpms reach 3000 before vehicles moves. Instrument panel lights going on and off, including the fuel gauge indicator. Over head dash light won't work. Took my SUV to the dealership on a Friday 11/09/01. All problems were occuring at that time and they could see for themselves. I was informed the the diagnosistic test showed 5 trans codes. And that wire to the transmission was loose and they reconnected that wire and all codes were now clear. The very next day my SUV began doing the same thing all over again. I called the dealership and reported the problem on Monday 11/12/01. I was then told that the problem may be caused be a wire leading from my ignition to transmission. And that I might need an ignition switch. And that to do the work it would cost me $400 to $500. And that they didn't think that the fuel gauge problem was related to this problems. There are time that I am unable to control my windshield wipers. I have read over 12 simular compliants & incidents. GMC need to repair these malfunction before someone is seriously injuried. I have almost been rear ender several times because my SUV won't accelerate properly. And to be driving along and suddenly have your instrument panel fails, this is distracting and unsafe. Also, my emergency brake will not hold. S.O.
