Approximately 14000 miles we were told a rod went through the engine. Our vehicle failed at a high rate of speed leaving myself, wife, and 2 young children to pull off a major highway and call for police to help slow traffic. This happened while driving 70 mph on the highway. The only warning we received was when the car went from D drive to N neutral on the highway. Fortunately, we had enough time to pull to the side of the road before complete engine failure. GMC road side was not helpful. We were told we would have to find a ride home over an hour away, and when our ride arrived, so did the tow truck. Then, they had to drag the vehicle onto the flatbed because the tow truck company did not have the unlocking device for the wheels. Upon getting it to our house, the tow truck company had to rock our vehicle off the bed! We were not able to tow it where we purchased it. We either had to tow it to the nearest GM dealer or our house. We chose our house because the nearest GM dealer from where we broke down would’ve been over an hour away from our house. Our second engine failed 2200 miles later while my wife was sitting at a light in a busy intersection. The car again went from D to N, and it was immovable. The cops had to be called because the tow company couldnt come fast enough. We were towed out of the intersection, but I waited over 5 hours with several dropped tows for a tow company. That occurred on my birthday. We are now on our third engine, and GMC wouldnt warranty the engine. Our brand new tires went at 32,000 miles because GMC could not confirm or deny that rocking our vehicle on and off the flatbed three times didnt affect the alignment. The front two tires inside tread was worn. I was told the tires from the factory are 50+ thousand mile tires. We barely got 32,000 miles. Weve had multiple issues with electronics, back up camera, and media package. The Lemon Law wont cover us because our first engine did not fail before 12,000 miles.
