2007 Jeep Grand Cherokee Laredo 4dr SUV 4WD (3.7L 6cyl 5A)
Between 40-45mph my JGC 07 stops accelerating. Hesitates for up to 10 seconds, then finally gets going again. After owning the car for 6 weeks, I was turning onto a highway and all the power cut off. Pulled over and couldn't get it to start. No electricity either. Let it sit for a few minutes, and it started again. Took it to the dealership and they said they couldn't duplicate the problem, so they didn't fix anything. Today, it jerked hard when I put it into drive. Barely got down the street at 20mph- turned around- and it sluggishly made it back to the driveway. This is a 2 year old car! We owned 2 other Jeeps that were great. This one is undependable and I'm pretty disgusted.
