NHTSA Complaint #11464738 — 2012 CHEVROLET TRAVERSE

First I already had to rebuild the transmission which is showing the beginning signs of failing again. Then around the same time I started having another issue that I find a lot scarier as the driver. It started giving me severely Reduced engine power, traction control off and stabilitrak messages with the ABS warning light lit up like a Christmas tree. This is by far the most dangerous of any issue I've ever experienced with all of my vehicles I've ever owned. It starts with a huge jump I cant stop or control to a car behind me it seems like I'm really getting on it and speeding up. But in a split second too quick for any human to process what is happening it just drops out big time. It then wont go above roughly 30 mph and the engine is revving very high to even get it to that. All the while it is heavily shuddering and jumping back and forth at a very fast rate and it does this with a high force to it. I have no control over it either. Before I could hit traction control off and it would all stop. However today it did this again for the first time in a long time and man was it 20 times worse than anything I had ever seen before. By the time I decided to turn back and go home (which I wasn't any further than a half mile into my drive to begin with) I made it maybe another quarter block and that is when the bottom fell out. It stopped moving at all at that point. Nothing we did to correct it that had totally controlled it in the past would help for the first time. In the end my husband hooked an o2 sensor to it and reset the codes and now it's back to driving beautifully. The reason I feel this needs recalled is it's a huge danger to myself and anyone else around me. When this starts you have no prior warning what so ever and then bam your all the sudden in a car that is jumping back and forth and its visible to other drivers then its starting like it's going to really go but it malfunctions so fast no one behind you would have time to react to such a sudden drop.
