Automatic Transmission Gear Indicator problems of the 2007 Jeep Grand Cherokee

While accelerating the vehicle lost power and the prndl lights all illuminated. After a few seconds power resumed. This has happened several times and the check engine light has come on. We have been told its error code u0404 and the electronic shift module needs to be replaced. It appears this is a very common occurrence for this year vehicle. It is a safety concern because if it happened during high traffic times it could certainly cause an accident.

The trans struggles to shift through every gear and wont shift past 3rd gear, sometimes even stalling me in traffic. Feels like it doesn't catch the next gear when accelerating. There have been times when I've been stopped at a light at an intersection and when I go to accelerate, the engine will just rev as if it's in neutral, but it's not. Therefore, the acceleration is very weak. When switching from park to drive, it either doesn't fully click into drive or it selects all gears (prnd) in which I then have to park the car and shut it off, then retry a minute later. I don't drive the vehicle as a manual so there should be no reason for it to stall, but I'm pretty sure the issue stems from the main computer in the shifter module. At times, it seems like the vehicle is expecting me to shift it from gear to gear, then it finally clicks and moves to the next gear on its own.

Jeep Grand Cherokee 2007, 25,000 miles. Suddenly decelerates and all of the boxes around the gears prnd light up at the same time. I need to puul over, turn the Jeep off, then restart to regain normal running. This could be a tragic problem if the Jeep were to suddenly decelerate on a highway with a full load of children.

2007 Jeep Grand Cherokee laredo, pulling onto highway vehicle experienced loss of power. Prnd on display were all selected and check engine light came on. Was able to pull to side of road , put vehicle into park, cycle vehicle off then back on and power was restored. Since the intiial occurance the event has happened twice more. Scheduled appointment with repair department.

I was driving at 70mph on the highway when suddenly the car "jerked" and the speed drastically decreased to 20mph. I was unable to accelerate. The check engine light came on and there was a box around prnd instead of just around drive. I got off the highway as soon as I could and drove to my local mechanic. The same thing happened to me in oct 2009 shortly after I purchased the vehicle, I brought it back to the dealer and it was fixed at that time. Now alittle over one year later the same thing happened. I am lucky that I was traveling when traffic was light or it most certainly would have caused an accident. I spoke with Jeep and they were not willing to offer any assistance unless I brought the car back to the dealer in which is was repaired before, I explained that the dealership is one hour away and I would not be driving my vehicle that distance and do not currently have the financial capability to have it towed that distance. They need to issue a recall on this situation.

Vehicle has stopped accelerating on multiple occasions. All of the prnd lights switched to having a square around them, normally, only the transmission position that you are in will have the square around them. While going 20mph the car stopped accelerating once until I came to a complete stop. Had to put on hazards and had to turn off car and restart it in order to move again - was at least 45 seconds with no acceleration at all. Problem has occurred five times so far. Four times I was going between 15-20, and once going 50. Check engine light has came on when this occurs too. Four of the times it has happened I just made a turn and started accelerating, and once I was traveling a straight path.

The car all of a sudden loses power and all the prnd12 light up. Some days it won't go into drive, then all of a sudden drops into drive. When driving on the highway if you slow down, you can't speed up again, like you have no acceleration. Once in a while the check engine light comes on, then it will go off again, most of the time you have no notice that anything is going to happen, you just lose the ability to accelerate. I see a lot of other people filing complaints on the same issue and have looked online and found many more that are having this issue.

The gear shift module is badly designed it uses a brush that drags along contacts to tell tranny what gear is selected. Over time though some of the conductive material starts to rub off and make connections between 2 or more of the contacts, when this happens the ecu and tranny can't tell what gear it's in and goes into limp mode 20 mph max a very dangerous situation I'm lucky I didn't get rearended by a very pissed off semi ruck driver recently. I'm sure some one has been injured and possibly killed by this badly designed and dangerous module. . Chrysler and benz were partners in 2007 and benz uses a touchless ( magnetic) system much safer. Jeep just keeps on putting in same part no improvements have been made the tcb tells dealer to put in a new part. The only warning sign you might get is all of the circles around the prnd on your dash will be lit showing you the module has no idea what gear it's in but no warning lights or buzzers. This has happened many times since 2010 always with the vehicle moving and all of a sudden very dangerous!!.

Bought used 2007 Grand Cherokee from adams Jeep, aberdeen MD in Nov. 2009. Within first month, while traveling around 30 mph, car would not accelerate when pushing on gas pedal despite engine racing. Prnd lights all lit up. Took car back to dealer and bezel gear selector replaced after paying $100 deductible on extended warranty. Same problem occurred 5 months later. Dealer charged me for electronic control module updates. One month later, same problem occurred, dealer replaced bezel gear selector again. One month later, same exact problem occurred. This is 4th time taking car in for lack of acceleration while pushing on gas pedal. Dealer states unable to fix problem since they cannot reproduce it. This is a huge safety problem as I have almost been hit multiple times when my car fails to accelerate when pushing on gas pedal. Chrysler needs to recall the shifter module in these cars before someone gets killed.

The contact owns a 2007 Jeep Grand Cherokee. While the vehicle was parked and turned off, a child crossed over the driver's seat to exit the vehicle. He held the gear shift to support himself, which caused the vehicle to shift into drive. The vehicle sped down a hill and crashed into a tree. There were no injuries and a police report was filed. The vehicle was towed to an auto body shop and the mechanic stated that the cable went into the shifting gear, which caused the vehicle to shift into gear without the key in the ignition. The body of the vehicle was repaired, but not the gear shift. The vehicle is still at the auto body shop. The contact would like someone from chrsyler to inspect the vehicle. The VIN was unknown. The failure and current mileages were 43,000.

I have been to the dealer 3 times for this issue. First it was my prnd lights would all light up at the same time and my acceleration would not work. Then my check engine light would come on and go off again after a few starts. Now the check engine light is on and the code is u0404 which I am told is the shifter/electronic control module. While searching this I have found hundreds of owners with the same problem, all right after their warranty ran out. I went to the dealer while still under warranty and it was not found now that I am 900 mil;ES past warranty they know what it is. I feel if this many owners have the same problem it should be recalled. I completely lost acceleration while on the highway twice and was almost rear ended.

I started the vehicle and started driving when the vehicle would not go faster than 20mph and felt like stalling out. On the dashboard it show that the vehicle was in p,r,n,and d all at the same time (circles around the letters). I call a Jeep dealership and they told me if the engine light didn't come on there's on code, so they can't fix it. Jeep also told me they never heard of this problem.

2007/ 30 000 miles. Shifter malfunctions intermittently and causes loss of acceleration by going neutral or sticking in 1st gear unexpectedly. Typically, all the letters are lift prnd simultaneously and check engine light comes on. Stopping and restarting (annoying and dangerous in highway driving) seems to reset the shifter. Dealer says esm part no 52124138ad is responsible for the problem. I believe for safety reasons, there should be a recall on this part before somebody gets killed as a sitting duck in the middle of the highway.

While driving, the prndl had lit boxes around all the letters, and dash indicators all lit up, and Jeep lost power as if stalling. It then "went" back into drive on its own. This happened over eleven times, with mileage starting at 1,186, and most recently at 52,536. Dates of repair incidents are : 2/12/07, 12/31/07, 1/10/08, 9/22/08, 1/5/09, 6/9/09, 6/18/12, 10/19/12, 12/26/12, 3/8/13, 3/22/13. My Jeep is a 2007, averaging 8,756 miles per year. I bought it new and I take very good care of all maintenance right away - oil changes, filters, tire rotation, etc. ! each time it was brought to the dealer for "repair" , they either couldn't find the problem, or replaced : shifter module (twice), transmission wiring harness (three times) and suggested a new battery (we replaced that also), and transmission plug and seal. There were also numerous "software and anti-theft updates. In addition to these, I replaced the driver's side window regulator twice. Now, they want to replace the "transmission temp circ. " and esm module - for another $1,500. 00 . All this in 52,536 miles and 6 years !!! I firmly believe there are serious manufacturer defects with this vehicle. My biggest concern is the safety of this Jeep is unpredictable. I never know, even after all the "repairs and replacements" , if it will suddenly lose power and I might be in danger (traffic, intersection, etc. ). How in the world could Chrysler deny this problem? it needs to be resolved at the source, they are responsible for the safety of their vehicles !!!! there are many reports of this same issue from numerous 2007 Jeep owners - where is the recall ???!!!!.
