Upon driving on the highway, I felt my vehicle's transmission change gears, which felt like neutral. My car slowed a bit but then sped back up, and then slowed again and sped back up. I then noticed the P, R, N, D were all lit up. I had no control over my vehicle's acceleration when this occurred. After I brought my car to the dealership, I was told the electronic shift module had to be replaced. After replacing it, three months later it occurred again, and was replaced again. Over the last 1.5 years it has occurred randomly, over and over, and now needs to be replaced again. This is a safety issue as the driver has no control over the vehicle's speed. Jeep knows about this issue but refuses to acknowledge that a recall needs to be issued, therefore making their customers continue to pay for the repairs. A recall needs to issued.

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 lost power (engine RPM went to idle) for no apparent reason while turning onto a multi-lane hwy and accelerating. Power was restored and vehicle accelerated normally. Vehicle "check engine" light illuminated. This has continued to occur several times in the last month. "check engine" code U0404 was verified through Jeep is the "tcm" transmission control module.

- Commack, NY, USA

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.

When my 2007 Jeep Grand Cherokee is in drive, there is a loss of power. The check-engine light comes on, and it's as if the car doesn't know whether it's in drive, neutral, reverse, etc. The dealer says I need a electronic shift module to the tune of $600+. after looking into this, I see it is a problem with many Jeep Grand Cherokee. I am looking into getting Jeep to take responsibility for the faulty part.

Car will decelerate, and will not respond to depressing of the accelerator pedal. Occurs at various speeds and traffic conditions. Contacted dealership, began to describe issue, without describing the make and model, and the repair-shop was able to then tell me the make and model of my vehicle without me previously disclosing. (already had gear shift module replaced once before, and since the issue occurred 14 months later, dealership refuses to cover expense of replacement.) this is a very dangerous issue, and as stated before, occurs at various times and traffic conditions, and there are no preceding warnings or other indicators that foreshadow the occurrence. Car is now at 42,000 miles, yet it is in need of a 3rd shift module, seems highly unlikely. Dealership needs to declare a recall or when the customer has the problem, they fix it without further expense to the consumer. I bought this Jeep new, and its my 4th one, however, I am extremely disappointed with their customer service, and the quality of vehicle they are producing, and will not ever purchase their vehicles again.

- Denver, CO, USA

I own a 2007 Jeep Grand Cherokee V6 2wd and other owners across the us (thousands of them) with years ranging 2005-2007 report problems with the electronic shift module. This goes out in the middle of driving (sometimes on the highway) and will cause the vehicle to stall out in the middle of the road without warning. I have had mine replaced twice now and have only owned my Jeep for 1 1/2 years (bought it brand new). This happened in March 2009 and again January 2010.

I was driving along at 70 mph in the number one lane when the motor just quit. I had to change over three lanes to get to side so I would be safe. There large trucks in the number two and thee lanes which caused me concern for my safety. The crankshaft sensor was defective causing the incident. I feel there should have been a recall because the sprinter uses the same engine which has been recalled for the same reason.

While driving 60 mph down busy road the engine died, when accelerator was pressed there was no power, dash went completely dark. Pulled to the side of the road and the vehicle would not go into park. After several tries it could be restarted. The shift control module has already been replaced due to previous problems.

- California, KY, USA

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.

- Woodstock, VT, USA

The engine stalls while at low speeds shortly after start-up. No engine diagnostic lights are present to aid in the troubleshooting. The car has stalled under the low speed conditions 5 times since purchase. The car currently has 27,000 miles.
