Had the CO reprogram on the engine control module and it destroyed the driveability with possibly a 10~15% loss of power. Under some circumstances is is almost dangerous to drive. Lack of power, engine misfiring, push on the gas pedal and it will actually slow down for a couple of seconds. The hotter the ambient the worse it gets and balky cold, 50F. Not a matter of AC on or off. This is not the vehicle I purchased. Runs worse than a carb car with no choke and a bad accelerator pump. This is an automatic and many times I have to manually shift it to get around town in traffic under 55mph. Bought an automatic for a reason. It will be going in for service in about 2 weeks see what goes there. This is totally unacceptable!!! NOT HAPPY!!! Anyone else have the same problem??? In the past fully certified ASE mechanic, 20+ years, and CA smog certified.

Yes,,,, Had a CEL a few months back ,, took it in ,, replaced the turbo,,,, but destroyed the radiator while doing so and let me drive it off the lot leaving big puddles of coolant everywhere I stopped ,,,took it back in and replaced the radiator,, went to pick it up up and left with no cold AC on a 98 degree day ,,, simple plug was off ,, got the recall in the mail for a reprogram ECM and took it to a different dealer,,, had to replace the ECM under warranty ,,, and my 2013 ECO is not even remotely close to being the same car as before all of this,,,,On long trips it will barely break 30mpg ,,,,,at 70 miles per hour it struggles to maintain cruising speed with out shifting up to 5th gear,,,,when I roll a yield sign I press the gas and I have to look down at the tach to make sure it didnt die ,, it lags so bad ,,and then it sometimes revs up to 4k on the tach and then the gear hits with a jerk ,,never know what to expect ,,,,
