Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Currently, my car has 62K miles on it. 2011 Buick lacross cxl AWD 3.6 engine. The car is jerking forward during the low speeds between 2000-2500 RPM, when I move my foot off the accelerator, tranny shifts from 1st gear to 2nd or 3rd to 4th and this makes a very noticeable forward jerk. I have noticed this 6 months ago when it was not very noticeable but now it is getting worse. Specially in the city, during the stop and go traffic it is really very annoying and dangerous. If I drive longer it gets worse and sometimes I have to slam on the breaks to stop or slow down the car specially if I am going downhill. This happens when I start accelerating slowly from stop, up to 2000-2500 RPM and then move my foot off the accelerator. Basically tranny shifts to the 2nd gear (or 3rd) and jerks very noticeably forward. If I keep on pressing the gas pedal, it keeps acceleration without any problem. In slow stop and go city traffic if I want to slow down or stop, I basically take my foot off the gas pedal, this causes car to shift to upper gear and jerk forward, sometimes in the traffic I need to slam on the brakes to stop or slow down. Happens only during the low speeds (10-20 mph), and stop and go traffic.

New Buick with less than 30,000 miles (18 months old), left rear wheel bearing went bad and had to be replaced. 48,000 (22 months old) both right and left (again) rear wheel bearings bad and had to be replaced. Three rear wheel bearings, less than 50,000 miles car less than 2 years old....seems more than a bit excessive.

I noticed this problem not long after getting car when stopped in drive going from brake to gas car seems to act like its on oil slick then catches on with a sudden jerk. It will also when going from gas to brake even on incline will lunge forward it also will just suddenly speed up with out any acceleration its like the car is in cruise control. I have had car in several times and always they cant tell me anything I'm not the only person who notices this anyone who is in car asks what was that or what just happened.
