Model years: 2009

Problem: General motors is recalling 276,729 my 2009 buick enclave, chevrolet cobalt, hhr, malibu, traverse, gmc acadia, pontiac g5, g6 and saturn aura and outlook passenger vehicles. These vehicles fail to comply with federal motor vehicles safety standard 102, "transmission shift position sequence, starter interlock, and transmission braking effect", and fmvss 114, "theft protection and rollaway prevention". On some of these vehicles, the transmission shift cable adjustment clip may not be fully engaged. If the clip is not fully engaged, the shift lever and the actual position of the transmission gear may not match. With this condition, the drive could move the shifter to "park" and remove the ignition key, but the transmission gear may not be in "park".

Risk: The driver may not be able to restart the vehicle and the vehicle could roll away after the driver has exited the vehicle, resulting in a possible crash without prior warning.

Fix: Dealers will inspect and ensure that the shift cable adjustment clip is fully engaged. In the event that the clip does not engage, the shift cable will be replaced free of charge. The recall is expected to begin on or before march 24, 2009. Owners may contact buick at 1-866-608-8080, chevrolet at 1-800-630-2438, gmc at 1-866-996-9463, pontiac at 1-800-620-7668 and saturn at 1-800-972-8876 or at www.gmownercenter.com.

I can't drive my car because the transmission shifts hard and is dangerous because the speed is fast the slow plus it just about breaks my neck when it shifts. It was about a day or two when i finally noticed it. I only drove it about one mile. My car only has 47,942 mi. On it and gm isn't helping.
