The 3.7L motor has blown a head. After researching online I see that this is a common problem for this motor but Jeep won't do anything or admit the problem. I spent over $20,000 on a american vehicle because I thought they were a trusted name. I should not be forced to spend $3000 getting a new motor because Jeep won't stand behind their product.

2005 Jeep has been slipping into neutral since February 2013. It caused me to have an accident because I couldn't get out of the way of rear-oncoming traffic. No major damage was done thankfully! a few weeks later I experienced a rollaway. I went into the sitter to pick up my son. After about 5 minutes of being inside I my Jeep roll across the street! I go running outside, opened the door and pulled up the emergency break...just missing an embankment! since the "neutral" thing started I have had several service lights come on. My mechanic performed a diagnostic check and he said its all electrical. Also, I've had issues with the front passenger window going up/down slower than the rest of the windows since 3 months into purchase. Other issues are cracked door handles (both front doors), replacing taillight kit, ac switch-a few times as it would only work on high.

The vehicle will not idle when hitting the brakes at a stop sign or traffic light or coming to a complete stop resulting in a rear end collision. From the vehicle not maintaining a normal idle position.this is a danger to the vehicle occupants and anybody else on the road.Jeep is aware of the problems and have not come up with a solution for the customers.I have seen this same thing reported to the NHTSA onrecord a million times and will see this issue gets addressed if I have to call a senator that is a good friend of mine somebody is going to answer for this! to read the amount of complaints that have been reported to the NHTSA and nothing has been done is unacceptable and I can assure you the NHTSA better investigate this immediately. This pertains to Jeep Grand Cherokee 2005 V8 4.7 liter motor found in 57% of all Jeep that were built. You can go to youtube and see this in a video of this happening and its also on the Jeep forums web site posted a million times.

When attempting to start the vehicle, I heard one click and nothing happened. Lights and gauges worked, but nothing else. Jeep was jumped and then started right up. It went two months and is now doing the same again. Within a week, it has done it 3 times. Battery replaced and starter checks out fine. Also gauges dim and then come back on within seconds. The alarm goes off whenever it feels like it. Doors sometimes will not unlock with the fob which sets the alarm off. Nav system only works when it feels like it. Low setting on heater doesn't work. This lemon needs recalled!!!

While driving for about 30 minutes, the gears changed from drive to the 3rd gear. Transmission reves up and the check engine light comes on. After coming to a stop, and restarting it, it sometimes goes back to drive mode, but reverts back to the third gear, displays "3" and stays there. Took it to a mechanic, could not fix. Dealer claims no recalls for this problem, but online blogs show plenty of people with the same problem. Help.
