2007 Jeep Grand Cherokee Laredo 4dr SUV 4WD (3.7L 6cyl 5A)
I just purchased a 2007 Grand Jeep Cherokee in November 2009. I have taken it back to the CarMax three times for the same problem. Vehicle mysteriously will fail to accelerate while driving or delay in shifting gears. (Once, it happened to me when I was entering the highway from an on ramp. I was forced to put the hazards on and pray someone did not run into me.) CarMax said they fixed it when they replace the shift module, but it happened again. This time the vehicle slowed down and then just cut off. I don't feel safe driving this anymore. I could have been seriously injured or killed.
