My MKC (2.0 FWD) does a real creepy thing when I need to accelerate from low speed. The transmission kicks down quickly but the engine just seems to almost die, feeling overwhelmed by the process. After a full couple seconds - literally, it takes off a bit unpredictably and non-linearly. If this is "turbo lag", it's very challenging to the driver - not to mention the associated and unacceptable torque steer in the speed build up.
I'm aware of this consistent situation and will avoid such situations until I can leave the car with Lincoln for a while. I doubt there will be anything appreciable done other than "re-flashing" the associated computer chips. We'll see. My MKC was one of the first purchased in mid-July so hopefully the people at Lincoln that are responsible for these issues have new cures. I have faith - and I'm a huge fan of the vehicle!
