This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
Vehicle appeared to hesitate and eventually stalled loosing power. All instrumentation lights came on during this event. Driver was able to coast to the side of the highway; place the car in park/neutral; and restart the engine. The same event has happened at least 4 other times since the first at varying speed (I.e. 35 to 65 mph) and there were no warning lights making this a very dangerous and unpredictable event. I took the vehicle to an authorized dealer and he stated that it could be the power control module; but was unsure. I'm very concerned with the safety of my family. The symptom of this problem (engine stall) is unpredictable and is a recipe for a serious and life threatening accident. I've reviewed hundreds of complaints reporting similar conditions. There needs to be a global recall on all 2007 Jeep Commanders reporting this problem to have this issues repaired before there is a loss of life resulting from this event. Nhtsb please respond to this complaint and compel Chrysler to issue a recall before it is too late and life threatening injury occurs.
This problem began in the fall of 2008. Typically, after shifting the car into drive, the car would not accelerate past idle speed, have a moderate bucking, all gear selector lights on the dash were boxed in, and an error message would read "service park assist system". the problem was serviced under warranty. The dealership checked wires and connectors, and replaced the bezel assembly on shifter. This seemed to solve the problem until recently. Beginning a few months ago, around the beginning of 2012, I am having the same problem with the exact same symptoms: All gear selector lights illuminated, no acceleration for 10-15 seconds, and service park assist system message. The problem occurs almost always in the morning on the way to work, school, etc.. it has never lasted longer than 15-20 seconds on any day, and seems to occur approximately one to two times per week, over the last 4 weeks. I have an appointment later this week at a dealer to check out the problem. But reading several internet sources, this obviously not an isolated issue, as there are many accounts of the same problem.
Doesn't accelerate sometimes." Service park assist system " appears on the panel. I've had the oxygen sensor replaces and still have the same problems from time to time. I pull into traffic and it won't go. This could very well do harm to my family in the vehicle. I'm worried!
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!

My boyfriend and I were driving home from dinner and about half way home the car suddenly stopped accelerating and the speed dropped from 70 mph to 40 and kept slowing down. We had to pull over and turn the car off and then back on. The car has done this several times since and a light comes on that says "service park assist". I have read up on this year, make and model and have found that this is a very common issue that has not been dealt with! this is also a very dangerous issue. I also found that it has nothing to do with the "park assist" but rather the transmission in the truck and that many have failed well before 50,000 miles but shortly after Jeep's 35,000 mile warranty. Jeep did not cover my car because I bought it used which terminated the warranty because I was not the original owner. I am very disappointed - this is my first Jeep - and I have wanted a Jeep for years. The car still decelerates at times - I can be in traffic or pulling off from a stop or turning a corner and all of a sudden it is not shifting or accelerating. I can't afford a new car right now but am concerned about my family's safety. Please read up on the many articles and comments from people about this problem and save lives!!! with so many complaints and close-call accidents I would think that since it is 2011 something would have been done by now!

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.
