Hi all, I'm wondering whether anyone else is experiencing problems with their Regal. I have been experiencing a rough idling, vibrations on driving and jerky gear shifting (mainly downshifting). The car also feels like I'm pulling a RV! No get-up and go like it used to have. I brought it to the dealership and apparently there were software updates from GM to improve perfomance but it's still acting the same. I'm very frustrated as the car is only 9 months old with 14,000 miles on the clock My poor Regal feels like a tractor and the dealership don't seem to know or care what is wrong with it. I thought I'd post this message and see if anyone else has had similar problems. Thanks!
