I have put just over 500 miles on my Malibu since I took it to the dealer for all the recalls and the faulty tire pressure monitor. The Service Rep told me that there were a bunch of recalls that had to be done so they had the car for several days and had to order a part. One of the recalls he mentioned was "Transmission" re-programing.... I was a little put off by this since for the most part my car has been pretty Ok for all the time I have owned it. Well most of the driving I did before I retired was commute to and from work approx 36 miles each way 65-70 going, 5 to 8 to 20 to 65-70 coming home. Now driving around town the Transmission shifts way different and if you let off and brake, it acts like it couldn't make up its mind to up shift or stay or downshift....jerky to say the least. I called the dealer and it was explained to me that the the computer/transmission had to relearn my driving habits/style....WTF is that. I drove it away from a dealer and got on the freeway and never had this now its got to learn my driving style. I'm happy they fixed the Tire Pressure Monitor under warranty, but if this transmission was a fix I didn't have to have shouldn't they ask first or is it just GM policy to fix it event if it ain't broke.
