I bought a 2007 Jeep Grand Cherokee from CarMax in VaBeach last June with about 25K miles. Two days ago, I was driving in traffic and suddenly I lost power. I could floor the accelerator and the car would barely move forward. All the other gears were fine. Also, when I looked down at the gear indicator lights, ALL seemed to have a box around them (PRND)! This would indicate that I was in all gears at the same time! I got the vehicle home and let it sit overnight. The next morning I drove it and NONE of the symptoms were present (shifted fine). It does sound like the electronic shift module mention before (an intermittent problem is usually electrical). I have an appointment with the CarMax Repair folks on Thursday. But since the car is not exhibiting the symptoms, I don't know what they can do. I'll keep you posted.Report it
