Since I purchased the car there have been a number of safety issues. The first was the transmission. I brought the car into the dealership 3 times with complaints of the car having spells where it was difficult to drive and on two of those occasions it nearly caused an accident. The third time I had to stop the car on a busy highway and have the car towed in for repair. The have since repaired the transmission. The second issue was the car was stalling intermittentaly. The final time I had it towed in and there was some electrical issue they have resolved. I am currently trying to resolve the third issue with the car. The car engine is reving very loudly and if I accelerate beyond 40 miles/hour the car lunges forward. I have not heard back from the dealership yet but this is the second time it has been in on this issue. I would also like to note I bought the car from classic Chevrolet and they lied about the safety features of the car. I was told that it had the latch system and when my son was born in may I found out that in fact it did not have the latch system. GMC has stated that they have no way to repromand the dealership for lying about safety features on cars. I purchased this car because I wanted a new safe car to start a family and I ended up with a lemon of a car that is the most mechanically unstable that I have ever experienced. I ended up on the side of the road stranded when I was pregnant nearly an dozen times.

Upon starting vehicle, the electrical system malfunctioned, causing the headlights, radio, and the dashboard lights to short out. This happened several times. The consumer had taken the vehicle to the dealer and they changed the sensors, however it did not solve the problem. There was noise in the steering wheel. The consumer was told that the problem was a characteristic. The hatch lock did not work, and the rear windshield wiper did not work. The oxygen sensor was changed twice along with the seat belt switch, the key lock on the driver door, battery, and the wiring harness. Also the cup holder broke.

Dont know where to start. Squeaking noise when going over bumps (sounds like it is coming from suspension). Metal grinding noise in brakes, ticking noise from engine, seat belt and airbag lights have come on for no reason, rear latch has come open while driving, tail lights and brake lights burning out freqently, transmission was slipping on take off, no cause found in the several times it has been taken in for this. Now my transmission is out. Just happened yesturday. Don't feel like I can blame the dealership after reading all the complaints. I think the fault lies on the shoulders of GM.
