Starting at around 55,000 miles while I would be driving my Jeep, the car would stop moving but the engine would rev as I pushed on the pedal. I would not be able to go in drive, neutral or reverse. I would have to put the car in park and turn off the vehicle, wait a few seconds then restart the car. I have had my car at my mechanics as well as a Jeep dealership, a total of 5 times, now ready to go back in for the 6th time. Each time I am told the problem is fixed and a day or 2 later it happens again. When I call to let the mechanic know I am having the problem again, I am then told that neither they nor the dealership know what the problem is and to bring it back in. Leaving me without a car for days. I have spent a lot of money on this vehicle and do not want to spend thousands more fixing a problem that is not fixable. I have 2 small children, and fear that somebody is going rear end the car when is just stops. I have contacted the manufacturer of Jeep and was told only "certain" 2006 Jeep were under recall, mine was not one. All I could do was make a complaint. So I made a verbal and now written complaint, hoping something gets done.

Check engine light would come on (& go off) repeatedly. Additionally, transmission would 'jerk' on deceleration just before vehicle stopped (light drivetrain had to catch up with the engine). Took vehicle to dealer, who stated there was nothing wrong. Returned several days later with same engine light illuminated. Dealer kept vehicle for over a week; finally determined a daughter-board on the transmission control module had failed and replaced ($600). Two days later, check engine light came on again. Returned to the dealer, who (after 3 days) determined that the entire transmission control module had failed ($1000 to replace). Replaced entire tcm (which other dealers told me seldom if ever fails). 3 months later, problem returned.

Transmission fails at highway speeds. Dashboard says its in drive but when you rev the engine its in neutral. I had to coast off the highway and restart the engine. It worked fine, but isn't it dangerous losing power in the middle of the highway with tractor trailers coming at you at full speed from behind? this isn't the first time it has happened. It happened many times before.

When driving my 2006 Jeep Grand Cherokee Laredo the lights around the pnd21 will circle all of the gears and either go into neutral or 1st gear on its own while you are driving it, it happens at least 2-3 times a week. It is very dangerous when you are driving down the road - have taken to dealer said it needs electronic shift module at a cost of $750. Called customer service Jeep they said they couldn't help with the cost of repair. I have looked into this problem and it seems that there a lot of these same 2006 Jeep with the same problem. They said my Jeep has to many miles 85,000 - but it seems like it happens to call Jeep no mater what the mileage - I think this is a defective part and they should make it right - now matter how many miles. This is a very dangerous problem. I have almost been in 3 accidents due to this problem.

I have a 2006 Jeep Grand Cherokee. 2 months ago while driving the vehicle without warning the vehicle looses power. It seems to drop out of gear. The vehicle cannot accelerate and you have to pull over and hope it will kick back in gear. I spoke with another 2006 Jeep Grand Cherokee owner and the exact same thing happens to him and also one of his friends. I went to edmunds.com and it seems this is a wide spread problem. We contacted Jeep and they said sorry it is out of warranty. This is not an isolated safety problem. I hope you can protect the american citizen from the sale and future use of faulty automobiles. These vehicle problems should be address before people die. Thank you.

At a stop sign, short of the cross walk, with foot on brake pedal car in drive waiting for traffic to clear so I can turn right on to the primary street. Remove foot from brake and 2006 Jeep Cherokee begins to move backwards. The is no incline or decline at this stop sign to allow for gravity to move car. Had to re-apply brake, put car into park. Shut off and restarted before proceeding. This same difficulty has now happened on at least 6 different occasions and dealer reports no mechanical issue evident to cause auto to move on its own in reverse. Yesterday, in the omaha world herald paper a story appeared describing an accident with a 2005 Jeep Cherokee.

I have a 2006 Jeep Grand Cherokee Laredo, 3.7L V6. I have many problems with the transmission, first it was the shifter, second it was a solenoid problem, now I have a shutter and vibration as I am driving down the expressway. I have had it in 3 times now for the same problem. When the tranny starts to vibrate, I notice that the rpms go up about 2-3000rpms. Took it back and the repair guy says that Jeep has recalled the torque converters for a shutter problem and could replace it up 100K miles. I have over 100K and it will not get fixed under this recall or tsb due to mileage, I think someone needs to take a hard long look at the time that Chrysler should have to replace at their expense. This issue has cost me well over $1000 so far and it is back in the shop for the same thing yet again today.

The transmission in my 2006 Jeep Grand Cherokee has been slipping. I had it checked out and I was told it is ok. Then a few weeks later, I take off from a stop light and my engine revs to 3000 RPM and I am losing speed in heavy traffic. Then the engine light came on. So I take it to the dealer. They check it out and tell me it is the electronics in the shifter that is bad. I ask what is wrong and the service advisor takes me to the mechanic. He tells me about the issue and says that they have seen alot of these issues and the back order on the part is 450 parts in the negative. I think this is a potential problem and should be investigated for a possible recall.

2006 Jeep Grand Cherokee make a grinding noise while turning. Consumer states that the mechanic could find nothing wrong with the vehicle. When noise occurred again it also made the entire front panel flash. The dealer informed the consumer the tires had been rotated and the griding noise should cease. The consumer was told the transmission was leaking, so the dealer replaced the O-ring and a bushing.

I was recently driving on residential road going about 35mph under normal conditions and the automatic Jeep Grand Cherokee Laredo 2006 stalls. The check engine light appears. Pressing on the gas pedal will rev the engine but it is like the Jeep is in neutral. Everything else seems to work accept the car is not in any gear. The dashboard indicates the car is in drive. I have to coast off to the side of the road. I turn the ignition off before restarting, then the car seems to run fine for awhile. This has happened 3 times over the last month. The first time I took the car into a local Jeep dealer where they could only fine old codes in the Jeep computer system noting inactive transmission problems which they since cleared and were unable to do much else. An error code for the O2 sensor was also found and the O2 sensor was replaced. I was told to try it out and let them know if it happens again. That was about 10 days ago. Since then I have had two incidents that have occurred over this weekend, I have yet to contact the dealer which I plan to do this week.

Transmission does not shift down when stepping on gas. Most often in the 1200-1500 RPM range. Vehicle tries to stay on same gear and is not shifting e.g. from 5th gear to 4th. If gas pedal is stepped on all the way, vehicle shifts down 2 gears, e.g. from 5th to 3rd, and spikes up to 6000 RPM. This takes about 1.5. seconds, leading to dangerous situations when changing lanes, entering a highway, or speeding away from critical situations. Already experienced several severe close encounters. The spike in RPM will lead to property damage since the transmission will blow soon.

I purchased a Grand Cherokee Laredo 2006 invoice no. 392118) on March 26, 2007 in tamiami Chrysler-Jeep, 8250 sw 8 street, miami fl 33144. A few days after its purchase I noticed a little jump when I accelerated, then I carried the car to tamiami Chrysler service on April 2, 2007. They informed me that it has transmission problem so my car must remain there for a transmission replacement. Of course I am using a rent car but I want my car back. It is too much time (25 days) and their answer: Transmission is not available.

We purchased in Oct. 2006, a 2006 Jeep Grand Cherokee 4X4, V6 with 5 speed auto transmission, VIN [xxx]. there is a safety problem related to this vehicle and transmission. Problem: The vehicle has no hill holding capabilities. In other words, when stopped on a hill, the brake must be held on with your left foot and your right foot on the gas pedal in order to move forward with out the vehicle drifting backward. In all the automatic vehicles that I have owned since 1958, including 1993 and 1996 Jeep Grand Cherokee, none pf them were without hill holding capabilities. The first time I stopped on a hill with this vehicle, I drifted backwards and almost hit the vehicle behind me before I realized what was happening. This to me is a very unsafe condition and something damiler Chrysler should be addressing. In expressing my problem to D.C. customer service, I just got lip service. This is why I'm expressing my problem to you in hope that a solution can be found. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6)

When attempting to accelerate after a stop, vehicle will only coast after attempting to accelerate. This also happens after making a turn; the vehicle will initially attempt to begin to move then will only coast while gas pedal is pressed. I have almost been in a couple of accidents because people think I am accelerating and they almost run into the back of me.
