I have a turbocharged Srx. I was attempting to make a turn onto a road, as I hit the accelerator, the vehicle hesitated for a significant time, as if the transmission was disengaged. After a second or two, it suddenly engaged. Additionally, there have been times when I attempted to quickly increase speed, and felt significant hesitation. This is especially dangerous when pulling on to a road with high speed traffic on it, the vehicle is unresponsive to fast acceleration. Sometimes there is even a revving, and a sudden "bang" as the transmission engages. I spoke to the dealer on several occasions. I was told this dealership did not sell the turbocharged version of this vehicle because of this issue, and nothing could be done, but they were aware of it. The service manager indicated he had one other vehicle like mine serviced at his facility which had the exact same problems, but they could do nothing. Ot sure of the percentage of 2011 Srx's with the turbocharger, but I expect it is low, and was discontinued in 2012. Not having the ability to accelerate especially in front of oncoming traffic behind you is inherently dangerous.
I noticed when car is on incline the transmission disengages and rolls back. This occurs when foot is taken off brake. The dealership noticed the same problem on other Srx"s. Service manger claimed he informed gm headquarters and no solution is available. Updated 09/15/lj.
