2 months after I bought my vehicle used I have had to replace ignitions coils, so many recalls and only had some replaced cuz of being told they don't have the part in store at the dealerships. The electrical system for heat and a/c don't match up when turning the knob and the defrost doesn't work 3/4 of the times. I get flashes of loss power and my tire monitoring system keeps acting up. Now my engine and transmission are failing and no one can tell me exactly what it is without paying $5000 for them to diagnostic it and take it apart!! where do I have that kind of money?? this vehicle was the worst $16000 I have ever invested in and have only had it less that 2 years!! I am scared on a daily basis to drive my kids anywhere in it let alone myself to work. I so wish I would've kept my Jeep grand cherokee but we need more room for travel. Well you can't travel in something that's unsafe and unreliable. GMC won't call or respond back and either will the dealership. Lemon law in michigan is for new vehicles only so I am basically paying for something I can't drive and I can't afford to fix. What do I do??.

My wife was driving home from work when she experienced erratic operation of her vehicle. When taking off at first the vehicle lacked power then suddenly the engine rpm raced and the vehicle lurched forward. The engine speed was uncontrollable with the throttle. At a stop light the vehicle would barely take off and suddenly engine rpm's would race and the vehicle would surge when throttle was applied. The vehicle was driven directly to the GMC dealership on the way home and at that point it was determined the reverse gear was completely inoperative. The transmission failed due to a broken reverse wave plate. Vehicle was delivered new 7/10/09 (less than 5 years). The transmission replacement final billing was $3,906. 54.

Current issue is a transmission failure, apparently the "3-5-r waveplate. " five months prior, my wife and children were traveling out of state. They experienced a sudden loss of power and were stranded on a rural highway not once, but twice. The vehicle was towed in to a gm dealership, "repairs" were performed under warranty, and we were told we could pick up our car. My wife (again with children in the car) made it less than 10 miles from the dealership before the engine failed again. This time on the bridge of a major highway. . . . No where to even exit the vehicle. After the second incident the engine was replaced (after 3+ weeks of diagnostic work). We were told the dealership was not able to identify the problem that caused the engine failure. Engine was replaced under warranty. Transmission had been shifting erratically for several months. At time of engine failure/replacement, gm dealership that performed the engine replacement advised us that the transmission shifts/slips were "normal" for this particular transmission. They advised a transmission fluid flush, which we authorized. Shifting remained abrubt, slipping continued, but as we were advised this was "normal", we continued driving the vehicle and did not seek further repair. Two weeks ago, (now six weeks out of warranty), the slippage became distictly more evident, vehicle at one point wound not continue forward motion through an intersection and had to be idled to roadside. After multiple calls, we were advised to take the vehicle to a local gm dealership. Diagnosis of 3-5-r waveplate failure was given. This transmission waveplate failure is a well documented issue that can cause driver and/or passengers to be put at serious risk for injury. Our hope is that an investigation will take place to require gm to recall/repair this issue before someone is needlessly harmed.
