Blueblackcruze

I have a 2012 Cruze LT 1.4 Turbo with the RS package. Car was great up to about 2,200 miles where it just started getting slower in performance and poor acceleration in full throttle or part throttle. Almost got hit by an 18 wheeler twice since the car would not accelerate. The rpm's rev'd up but the car went no faster. Many possibilities I have been looking at and the dealer has been no help 4 times. Now about to go to another dealer. Its possible the transmission is slipping or not communicating properly with the engine. Other thoughts are that its the turbo charger or waste gate actuator. It almost feels as if it just dumps out all the boost. I am going to have to do my own diagnostics and T-tap a boost gauge to see if it still makes boost when accelerating in part throttle or full throttle. The traction control light did come on once for a few seconds while on the highway so obviously the tires were not slipping. I am going to have to get to the bottom of this myself because I dont expect any positive help from the dealer or GM. But I will be logging all of my time and someone is going to pay for the bill. I did not buy a brand new car to get jerked around. I even let the dealer know that I have a lot of experience with turbo charged vehicles and I use to diagnose some turbo car problems for Porsche but I guess they feel they are smarter then I am or that my detailed explanation of the problem is a fabrication. I even took photos of the gauge cluster mpg readings on a recent road trip to FL and the car was getting about 27mpg hwy at 61 to 65 mph and before I started having the problem I was getting 32 to 35 at same or higher speeds and there was no acceleration or hesitation problems. And it was in 85 to 95 degree temperatures. The car performed worse in cooler temperatures which is not suppose to happen in a turbo charged car. Turbos like cooler air and vehicles are suppose to perform better with the cooler temps. So there is something wrong with one or multiple mechanical parts or sensors. This is my first time giving a GM product a try and trying to support the U.S. economy but I am very disappointed. And having GM Customer care from the Phillipeans contact me does not sit well with me either. I hope some of us can get our notes together and find out whats going on with these cars.
