general problems of the 2011 GMC Sierra

The tbs goes out. Putting the truck into reduced power. I was going 65 mph and the truck slowed down to 15 mph on the freeway. Lose all breaks control , abs goes out to. Almost have been due to gm.

After applying brake to slow down to < 5 mph (not coming to a halt) and then trying to accelerate, vehicle becomes unresponsive for 1 to 2 seconds; it feels like the transmission goes into neutral during the braking period and when gas pedal is applied, there is a 1 - 2 second time period where vehicle is trying to figure out something and prevents any acceleration. Why is this dangerous? I found myself in a left turn only lane/green light with opposing traffic, and I attempted the left turn with oncoming traffic because I thought that I had ample time but the vehicle just sat there for 1 - 2 seconds, and with that I found myself in a dangerous predicament because the oncoming traffic was getting very close. If the vehicle had responded when I needed it to, it would not have been a close call. This behavior with the vehicle can be reproduced at will, every time. There are many forums on the internet where many people are complaining about this same issue with the drive-train, GMC knows about it, but refuses to do anything about it.
