In owners' own words
From the time I bought this car, I have had an issue where when driving the car, as the transmission shifts from the different gears, the shift will be extra hard.
Stopped car put into reverse, jerked well backing up, selected drive and car jerked going forward.
I was driving my Pontiac G6GT and came to a stop sign. I stepped on the gas and the car revved at high rpm's. I could not go forward I was able to go in reverse, I have a 4 speed auto transmission.

Recalls for the 2008 Pontiac G6: 5
The affected steering shafts may have a yoke that inadequately supports the u-joint bearing resulting in a premature failure. A joint bearing that fails prematurely may cause separation of the u-joint resulting in a complete loss of steering control, increasing the risk of a crash.
In the affected vehicles, increased resistance in the Body Control Module (BCM) connection may result in voltage fluctuations in the Brake Apply Sensor (BAS) circuit. Any of the above failure conditions increases the risk of a crash.
On May 22, 2014, GM increased the recall to include an additional 1,074,899 model year 2004-2008 Chevrolet Malibu vehicles manufactured from May 16, 2003, through October 5, 2007, model year 2004-2007 Malibu Maxx vehicles manufactured from June 25, 2003, through April 5, 2007… If the transmission shift cable fractures while the vehicle is being driven, the transmission gear selection may not match the indicated gear and the vehicle may move in an unintended or unexpected direction, increasing the risk of a crash.
In the affected vehicles, there may be a sudden loss of electric power steering (EPS) assist that could occur at any time while driving. If power steering assist is lost, greater driver effort would be required to steer the vehicle at low speeds, increasing the risk of a crash.
On these vehicles, the tabs on the transmission shift cable end may fracture and separate. If the tabs were to fracture and separate, the shift lever and the actual position of the transmission gear may not match.
A recall may cover only some cars of a model year; the campaign size counts every model and year it lists. Enter your VIN at nhtsa.gov/recalls: dealers fix open recalls free.
