When driving the vehicle the low engine power light came on and car went into limp mode and would go no faster than 20 mph. I turned around to head home and pulled over and shut it off for a few seconds. When restarted ran fine for a couple days.I took it to dealership and they said it needed a new throttle body. I asked if this is normal and the service advisor told me that GM knows about this and that it happens on cars less then one year old, but GM won't do anything about it because it is not a safety concern. The advisor suggested that if I did the repair myself not to but an GM unit as they are having problems with the replacement parts. I purchased a new unit from after market co. No problems since. Then 8/8/14 with 91,000 the same thing happened again, took it to another dealership was told fuel pump was bad. I took the car to a reputable mechanic they replaced the pump on the information from the dealership, but it did not fix the problem, was told could be fuel pressure module. Will find out today if that fixes it. My big problem with all this is that the car is five years old warranty has expired and these repairs are not cheap. If GM knows about thousands of defective parts why are they not doing something about it or being made to do so.
