Over the past few weeks while driving the vehicle will flash a warning saying service park assist system. When this happens the gear display on the dash prnd will all 4 get circled and flash and then as you are accelerating you can feel the vehicle lose speed. You can no longer accelerate the vehicle and have to coast off the road. Once you stop and shift to park then back to drive it will reset and then allow you to accelerate. I was going 65 on the freeway when this happened last and this is a major safety issue. For about the past 30,000-40,000 K miles we have had issues with it shifting properly and every time we took it to the dealer they can never re create the issue. Now we are receiving this warning and it actually stops accelerating on its own. It is happening more and more. We took it to the dealer since this warning now came on and they said they have never heard of it, they couldn't re create it, that it has nothing to do with the shifting and to turn off our park assist system so it doesn't happen. We are attempting a different dealer today but first thing they said is they never hear of this either. So comforting!

The contact owns a 2007 Jeep Commander. The contact stated that the vehicle would not shift into gear, it suddenly stalled at 70 mph and the steering wheel locked up. The contact turned the vehicle off completely and restarted it. The failure seemed to correct itself after it was turned back on. The vehicle was taken to an authorized dealer who stated that the shifter module was defective. The vehicle was being repaired at the contacts expense. The manufacturer was not notified. The current and failure mileage was 50,000.

My 2007 Jeep Commander refuses to accelerate after the service park assist light comes on and all gear options highlight at the same time. This will happen without warning while driving down the road and or highway. The only way to get the vehicle to begin to accelerate again is to put the vehicle in neutral and apply the accelerator. It will also begin to accelerate while at a stop on its own. I have read many complaints of this exact and similar problems from other Jeep Commander owners. I have been waiting for a recall for this issue since other Jeep Commander owners has been charged for replacing transmission modules just to have this happen again. My Commander is a 2007 V6 automatic transmission model. Here are a couple links I have found on issues. Also www.consumeraffairs.com/automotive/jeep_accel.htm.

I purchased a 2007 Jeep Commander in 10/10 while driving it I have noticed it hesitates at times. While driving the car today 02/09/11 it would not accelerate above 40 while I was on an on ramp. Lucky there was little traffic and I was able to pull over safely. I am taking it to the dealer tomorrow. I do not have warranty on it as I had bought it used. This need to be recalled and repaired by the dear. They know about this problem but they aren't doing any thing to fix it. Foul!!!

After ignition the "service park assist system" warning comes up in the control panel, then the rest of the warning lights turn on, then after driving noticed that the speedometer was not working, then the vehicle would stall while driving, the accelerator does not respond, I was able to park on the side of the street, luckily it was not a heavy traffic street.

2007 Jeep Commander, started with "service park assist" light coming on along with the check engine light. Took it in for service, they could not determine the problem so they reset the system. Two days later the same thing began to happen again, along with the lights around the P N R D on the display coming on all together, the car also then began to not want to accelerate after a certain point. Almost acting like it was not wanting to shift to the next gear. This happened for 8 months, still no service was done because they were unable to recreate the problem. It began to occur while driving and coming to a stop and starting to go forward again. Causing problems crossing intersections or traffic. Have now been told to replace the transmission control module, which we did. This did not fix the issue. In the last week were told to replace the electronic shift module.

Transmission stalling while driving- according the dealership service this is a problem with the electronic shift module. This has happened several times and is also a noted problem in these vehicles. This same vehicle has already been recalled for similar issue, but only for the bigger engine size. Chrysler has informed me that they will not investigate even though it is the same problem in a different engine size. The vehicle can be traveling at 70 mph on the interstate and stall without warning. It will not go any further without stopping, turning off the engine and restarting. This happens several times daily. I have tried to get fixed and work with the problem, but after almost being rearended by an 18wheeler on the interstate today, enough is enough. It is for 2007 Jeep Commander 3.7lt.

Purchase a used 2007 Jeep Commander on Nov 2007 from dealership. Two years in possession. The Jeep Commander, gears will all light up and stall at 30 RPM for two in half months frequently. Without the dealership able to establish cause, I had to wait for the engine light to come on. On December 11. 2009, during the last two days, simultaneous the gears will light up while, the speedometer became irregular causing me to restart the Jeep consistently to reset it. Finally, the dashboard engine lights up and I turn it in to the dealership on December 12, 2009 the next morning. According, to dealership located in hampton, va. The problem is concluded as the shifter, not cover by the 4 star warranty however, after researching your database, I found similar problems with the power train and transmission software module. The Jeep is now located at the dealership for repair however, a major problem after 2 years and 40,000 miles in service should not be the cause of ware and tear.

When the cruise control is engaged at highway speeds and the vehicle is traveling down a hill the cruise control will properly downshift to slow the vehicle and keep it at the set speed. If the vehicle is then shifted into neutral, the cruise control will disengage properly and the transmission will go into the neutral gear, but when shifted back into drive the transmission will re-engage and will slow the vehicle extremely abruptly as if someone slammed on the brakes with full force and will nearly lock-up the rear wheels on dry pavement. This will occur even if the cruise control is turned off before shifting back into drive. This has happened to me twice because of the placement of the shifter, and it was terrifying because of the speed I was traveling and the abruptness with which the vehicle slowed. If anyone would have been behind me I would have been hit and there is nothing that can be done to make the transmission not do that once the transmission has been shifted into neutral. The vehicle would become completely out of control if driving on anything but totally dry pavement.

I own a 2007 Jeep Commander at about 10,000 miles it started to stall and turn off. Dealer did not replace any parts only flushed the on board computer and updated the software. Months later it started to do the same thing. Dealer did not find anything wrong and performed the same task of flushing the computer and updating its software. Two years and 23,000 miles and the car is having the same problem. I have an extended warranty so I'm going back to the dealer, but I don't think they we fix the problem.

The contact owns a 2007 Jeep Commander. While driving between 50-60 mph, the transmission failed and the vehicle shut off. The vehicle was able to be restarted five minutes later. The contact has taken the vehicle to the dealer on three occasions. The dealer stated that the cause of failure was due to the key in the ignition, the transmission, and the converter needed to be changed. The current mileage was 13,200 and failure mileage was 9,000. Updated 03/04/08. Transmission fluid was leaking from the valve body connector area.
