Steering: clicking noise when turning transmission has a light slip into 1st and sometimes hard shift into 2nd had this looked at in 2013 while it was still under warranty and the dealer didn't want to acknowledge there was a problem. This should be under recall since more people have this same problem.

On more than one occasion, my car hesitated after stopping at an red light. Upon take off while other cars are behind me if feels like my car gears are stuck . I initially thought perhaps it was the weather or maybe my brakes . No, not the problem because my brakes have been checked and the weather is not always a culprit, I even have new tires . The problem is very scary when your grandchildren are buckle up in the back seat and your car hesitate, transmission slipping not changing gears. This has happened far to many times for my comfort and safety of myself and my family. Additionally, there also been times when the fan stop during this time. Both in the summer with the air blowing and just today (11/12/14), with the heat blowing everything stopped intermittently, what is going on with this car! The problem has only gotten increasingly worst.

Soon after purchase, transmission slips gears coming out of a stop. August 2013, transmission dropped out, driving 30mph. Car was not drivable; no gears. Transmission was replaced. Now one year later, slips gears at 40mph. Headlights went out while driving in the dark. Use of turn signals causes high beams to activate. The cabin fan (A/C and heat) never shuts off. Heat works intermittently. Car seems to shake at times. Feels like a flat tire but when checked, tires are fine. Car rolls when in park, even on flat surface. Car rolls back when in drive, even on slight inclines. Never certain of brakes; at times, works as normal, other times, pedal must be pushed close to the floor to activate brakes.

The initial issue that I noticed was when I was driving at 70mph at about 2000 rpms the rpms would jump up about 300 rpms when I would drive at a steady speed, just flat ground. It got worse and more frequent as a month went on, so I then brought to a gm dealership and they decided to do a transmission service (fluid and filter) and inspect what they could, everything "looked good". Now since then this issue has been resolved but the transmission slips and slams into gear, when I am in stop and go traffic or hitting a lot of stop lights, engine temp. Does seem to get a little high, even my mechanic thought so. When it slips it feels as if I hit a giant pothole and the engine/transmission is going to fall out. But this problem is so intermittent no one can pin point the problem, I have had three different mechanics look at this issue and one transmission shop. I have all of this and can't seem to resolve the issue, and not to forget to mention since I have owned the car since 2006, it has never shifted smoothly from first to second gear (when I accelerate from a stop light/sign). I like gm, but when this issue is all over the internet and gm hasn't done anything about it, I am starting to second guess my decision on vehicle manufacture.

My mechanic insisted that I needed to change my transmission fluid in order to keep the transmission running efficiently. I believed him and had it done. From that time, my transmission has been slipping from 1st to second gear. Then I was told my car could use a tune up and that would correct the problem? Had a tune up in january 2014. The trans does not slip all the time, but when I am in traffic (stop and go) it will slip slightly. I take good care of my vehicles keeping up with the maintenance. I see other complaints very similar to mine and feel that general motors needs to be responsible for this problem with the transmissions. Now, what does it take to get a response on this situation? The way I feel now is that I will never own a general motors vehicle if there is no resolution to this problem.

I been having problems with the transmission, it slips and gets to hot, in a normal trip to work o the mall etc, if I drive for 30- 40 mints, it reach up to 240 degrees, I think is a car defect, when I bought the car the transmission died and the dealer replace the transmission, but even though it was a new trans. It also run to hot, I called gmc and they denied any transmission problems.

The transmission is slipping as I have seen many others with this same complaint however one dealership says they cant find issue. They drove for only 2 miles. It is a serious issue. Currently at a gm dealership to solve issue. However gm knows about this faulty issue and refuses to issue a recall after many have spent thousands to fix transmissions! I am next this is terrible. What if it completely goes while I have my family in the car? Are they then going to fix? Gm needs to stand behind the consumer and fix this issue.
