Sorry to hear the problems you are experiencing with your Regal! Have you had the chance to bring this to the attention of your dealership? Please keep me posted.Does anyone experience a 3 or 4 second lag when trying to pass ? The engine just Boggs right down and then all of a sudden takes off. Seems like a torque managment problem.
Also as of late when downshifting the transmission binds and I hear a metal to metal pop when going up a gear.
Also the engine is very rough and getting louder and worse. Seems like I have some serious problems for such a young vehicle.
3 issues in 1 year.
