Ever since I had my car serviced about 3 weeks ago my car has been sluggish and acceleration has weakened, also I'm getting poorer gas mileage. The recall that was fixed has greatly reduced the performance of my vehicle.

Shutter/hesitation upon take off. I signed my lease on 9/29 and was at the service dept first of 7 times on 10/4. at first I was told the car had to "learn the way I drive" that there were no issues with my car. Since then the dealer has "reset" the transmission, changed fuel injectors, replaced transmission, and now has done 'several updates' (seriously?) this car has nearly caused accidents on numerous occasions. When I asked the tech if he would drive his family in this car I got no response. I have asked on the last 2 trips to the dealer for them to simply replace my car. I am currently consulting a lawyer.
