We have the na 2.4 and have 11k on the car now. Ours was also an early production regal. No problems so far also we had the ECM updated last month. To me I didn't see any difference in performance or milage

what octane are you using in your car? you should be using 91 octane and above.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 clockMy 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!
I had a similar issue, it was hard to find and I had to show the dealer. Our cars should have a fuse block recall soon. This is related to missing cooling fan pin-outs on the fuse block. Our gauge always reads about the same even when the car is running at 250 deg. My car felt so slow as temps would rise and ran like crap. Again you cannot see this on the gauge. I used a data logger to capture the real temps. dealer replaced the fuse block and the issue is gone. The fan has 6 speeds I think and speeds for temps between 212 and 230 could not turn the fan on. If this is also your issue you will have to ask your dealer about the recall, and to check the real temps not the gauge.Hi all, I'm wondering whether anyone else is experiencing problems with their Regal.

Thx..what data logger did you use? something that plugs into obdII port?
I use Palmers scan XL with a Tatrix ODBII port connector. The entire setup was about 250 I think. The scanxl pro software is more expensive, and not needed for most of us. Our cars cut timing and other things to try and keep from damaging themselves when over heating. my car felt like I was towing a house until this was fixed. It would happen quicker on hotter days and take an extended drive on cooler days to notice the performance issues.
Hope that helps.

JAC113,I have been having the same problems with my Regal. Have been back to the dealership three times and the problems still persist. My car idles/rumbles so loudly my dishes rattle in the china cabinet above the garage, shifting at lower gears is inconsistent at best ~ lots of hesitating, slowness, revved up RPMs, and now it's taken to jerking forward when idling at a stop light. I feel like I'm on a really bad carnival ride. I have called Buick twice to complain and while they are VERY nice people, nothing has been done. Please call!!! If enough of us complain either they will REALLY fix the problems or initiate a buy-back. 800-521-7300
I believe this is normal for the Regal turbo. At least I hope so because does the same thing.I have the same problem. When I initially star the car it revs a little hard but then goes back to a nice soft pur. On the highway is a different story, shifting in between the miles of 0-40 is nice and smooth however anything more than that the car seems to lag a little bit on the shift. It feels as if when the car is suppose to change gears it revs super hard, then changes.
We took in our Regal that only has 8000 miles on it to the Dealer for the first time, They ran the VIN and told us that the car has had a SOFTWARE UPDATE roughly about a year ago but that regardless they would look into the problem.Hi all, I'm wondering whether anyone else is experiencing problems with their Regal.
