Started truck shifted from park to drive. Started to drive, truck lurched forward and was unable to get it to speed over 20 mph. Tried pulling over and putting in park, still was unable to get truck to drive normally. Had same issue previously, had truck repaired was told that it was the electronic shift module - along with the battery, transmission control module and alternator - this seems to be a problem with this particular model - when will they recall this - do we need to wait for someone to get killed before some realizes there is a problem?.

At high and low speeds, and when stopped without any warning my 1996 Grand Cherokee will die and immediately steering is lost. This is totally frightening and life-threatening. The car will start immediately to get out of roadways. I've spent days researching this situation on-line and it is outrageous that there is no recall, there are years of complaints about this situation . I called Jeep today at 1-877-426-5337 and was told the phone number of a Jeep dealer, along with sincere apologies that there is no recall for this problem. The solution may be that 2 screws associated with the pcm are too long. People have spent thousands and thousands of dollars fixing everything on these Jeeps but nothing has worked. I respectfully demand to know why there is no recall, this is a public safety issue!!!!! thank you for your prompt reply. Lives depend on it. This is a life-endangering situation - mine and others. There needs to be a recall now.

Engine suddenly cut off while driving, power brakes and steering were immediately lost, although lights and gages remained operational. Battery and grounds tested fine. Cap, rotor and plugs are all new, wires and coil test fine, and vehicle has new mopar crank position and throttle position sensors. Research on Jeep technical sites finds identical problems being traced to failure of power control module pcm, sometimes also referred to as engine control module (ecm).

Engine stalls either at speed or during idle after 20 minutes. Will continue to stall for about 4 minutes, sometimes very hard to start during this time. Then vehicle will run fine with no problems for several hours. The next day, or after vehicle has been sitting for several hours, the process will start again. Every day it will stall after about 20 minutes - sometimes while turning, which will cause a total loss of steering ability, or while on the freeway, or while at a red light or intersection. I narrowly escaped an accident when it stalled and a big rig almost slammed into me. I have been stranded in the middle of a busy intersection multiple times because of this. When the car stalls, sometimes it runs very rough and backfires, which caused the catalytic converter to blow out. Now the catalytic converter rattles and caused my emissions test to fail with high no(ppm) output. I'm going to need to change the pcm and the catalytic converter to fix this, but this was covered under a recall for 1996 vehicles with this same problem. Jeep issued an emissions recall in late 2006 to update the powertrain control module (pcm) software on certain 1996 vehicles. As part of the recall, the catalytic converter will also be inspected for damage and replaced as necessary. 1997 vehicles experiencing the exact same problem were not included in this recall for some reason. Please include the 1997 vehicles in this recall.

My Jeep transmission is defective and keeps blowing filter off or splitting them. . . When this happens I am traveling down the road at 60 mph. . My vehicle jolts as if I have slammed the gears in park. . . This could result in major injury if the wheels lock while im going that rate of speed. . . After extensive research online I have found that many consumers who have 05 Jeep Grand Cherokee are having the same problem however the dealerships seem to deny the fact that there is an issue with the components of the transmission. . . I have found many consumers have had issues with the transmission control module, shift solenoid, and the filters for the transmission. . This has been a ongoing issue and I am surprised that this has not been recalled. . . This can happen at any time. . . While driving down the road. . . Or pulling out in front of traffic. . . . I am worried that I will crash or someone else will crash into me in the event that my transmission fails again. . . I have had it repaired 6 times over 3 years now for the same issue and no longer feel safe while driving. . . I would like to have this matter investigated with Chrysler, llc so that they may recall the products and take the time to repair these defective transmission components. .

Failure Date: 01/15/2011

Vehicle entirely stalls without warning at idle or very low speeds. Jerks and flashes check engine light for one second occasionally while driving at normal road speeds. Happens multiple times a day under no specific conditions (cold, hot, wet, dry, etc. ) intermittent problem so codes cannot be detected. First occurrence was in heavy mid day city traffic in the middle of a turn. Could not be restarted from park for 10 minutes, blocked entire intersection and entrance to plaza. Was almost hit by oncoming vehicles multiple times. Has the potential to be extremely dangerous if this happens in traffic as it has before. Bought used. Appears to have had pcm, air filter, plugs and wires replaced. Stalling issue is obviously extremely prevalent amongst this vehicle and must be addressed by the responsible companies before someone is killed, likely before more people are killed.

After being parked the Jeep would not start, code displayed in the dash stated transmission over temp, after sitting for about 30 more minutes the Jeep started - drove home and it would not start again - took it to a garage and they could not get the problem to replicate after having it for a week. July 5, 2011 - Jeep would not start again, transmission over temp code, still intermittent, after 2 weeks the garage replaced the transmission control module, August 6, 2012 - transmission over temp error code, this time it will not start after any pause in driving, had it towed to the dealer and they are saying its the starter (Jeep now has about 65,000 miles on it) - also had to replace the right front speed sensor (it is bad and causing the traction control system not to function properly). [additional notes: had to replace the esm at 28596 miles, Jeep loss of engine power and all lights lit up on gear shifter, at 27170 miles had to replace both front window regulators].

Failure Date: 08/24/2010

We own a 2005 Jeep Grand Cherokee. When the vehicle was 2 years old and at 35,000 miles the check engine light came on indicating the transmission control module. This was replaced under warranty. My husband was kind of concerned that they had the part in stock for a two year old vehicle but we had it fixed and went on. Now it is three years later at 89,000 miles and the same part needs to be replaced. They want us to pay 750 to have it replaced. We filed a case with Chrysler and they want us to have it diagnosed for 89. 00 at their dealer and then they will discuss whether they will help pay for it or not. There are many other people on the web that have had the same issues. Our car will light up all the gears when you are driving down the road and will not shift properly due to the engine not understanding what gear we are in. I do not want to have to worry that they fixed it and helped us this time but in 2-3 years we have to do this all over again for the same part. The gentleman my husband first talked to at the dealer we consulted before talking with Chrysler stated that he has also replaced this same piece in his Chrysler 300 twice. I have also seen on the car forums that the Jeep commander is doing the same thing and there are numerous complaints out there about the 05 Jeep cherokee. I would like to know why Chrysler continues to put this part that is obviously not working in their vehicles. This is causing issues for the cars and I am not convinced I want another Chrysler product. The gear shift should not be having parts replaced. I have been around many vehicles and never had this type of problem. I do not understand why a recall or something hasn't been done on this particular part. Why would they not find a new way to do this type of gear shift that doesn't fall apart in two years of driving. This is a family vehicle. This is not a race car or even a 4wd. I just want to get help in case others are still dealing with this.

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.

The contact owns a 2007 Jeep Grand Cherokee 4x4. While the contact was driving approximately 65 mph, the entire instrument panel illuminated intermittently. The vehicle suddenly began to decelerate. The vehicle was taken to an authorized dealer for diagnostic testing on two occasions for the similar failure. The technician stated the problem could possibly be contributed to the esm or either the pcm. The vehicle was not repaired. The manufacturer was notified of the defect. The approximate failure mileage was 50,000. The VIN was unavailable.

Failure Date: 11/01/2008

The contact owns a 2008 Jeep Grand Cherokee. While stopped at a red light, the vehicle began to shake and lose power. The vehicle was taken to the dealer to have the pcm programmed. The pcm did not stop the shaking; however, the vehicle no longer jerked forward. The vehicle has been at the dealer five times for the shaking issue, but they cannot remedy the failure. The contact feels that this is a safety issue because the shaking and jerking almost caused a crash. The current mileage is 11,700 and failure mileage was 5,514. Updated 6/4/09 the rear view mirror was out of frame, the engine had a rough idle and it felt as though it was going to stall. Updated 06/09/09. The consumer she and her husband were displeased with the arbitration boards' decision. The consumer stated the vehicle would surge forward and vibrate when at a stop and would feel as though the vehicle would stall, even more without the air condition turned on. The explanation the consumer was given that the air condition will cycle on at the same time the cooling fans which was said to cause the problem. Updated 11/02/09.

2008 Grand Cherokee 4x4 4. 7l flexfuel stalling at various highway speeds. Throttle lagging, harsh up/down shifting, hesitation on torque demand, fuel mileage reduced by 20%. After the first two stalling occurrences, the dealership replaced the fcm (front control module) since the serial number of the installed one-337- matched the February 2008 recall, although Chrysler database VIN recall search came back empty??!! the third and fourth stalling events were followed up by the replacement of the pcm (powertrain control module) since a "soft fault"-"torque request denied" was found stored within the controller. However, after six hundred miles, a fifth stalling occurred. This time a hard fault related to the map sensor (intake manifold absolute pressure) was found. The replacement was scheduled in 48 hours. There were six dealership appointments(only two documented though ??!!) and it was invariably either "we have to order the part" or "there is nothing wrong we could point at". The almost new vehicle is not safe to be driven on public roads. Yet Chrysler never provided a temporary replacement until the safety hazard could be located and eliminated. After every attempt of solving the problem, the customer is sent away to try his (her) good luck with a vehicle which might be okay. I don't think this a professional approach for both Chrysler and the dealership servicing the vehicle. Guessing and safety does not belong within the same sentence !.

Failure Date: 08/16/2007

The contact owns a 1999 Jeep Grand Cherokee. While driving 60 mph, the engine stalled. The contact had to quickly pull the vehicle off the road to avoid a crash. While his daughter was traveling up an on-ramp, the vehicle stalled and was unable to be restarted. By the time the contact arrived to assist, the vehicle was able to be restarted. The failure also occurred while driving 40 mph. The contact replaced the fuel filter himself before calling the dealer to inquire about NHTSA campaign id number 08v203000 (power train:automatic transmission:control module (tcm, pcm)). The VIN was not included in the recall. The failure mileage was 110,000 and current mileage was 120,000.

The contact owns a 2006 Jeep Grand Cherokee. While driving 50 mph and depressing the brake pedal to stop, the vehicle would abnormally lunge forward. In addition, while driving highway speeds, the vehicle would sporadically fail. The contact took the vehicle to a dealer and they repaired the tcm. Several weeks later, the failure recurred without any warning. She called the manufacturer and was referred back to the dealer. The dealer stated that if the diagnostic machine did not provide any codes, they could not successfully remedy the failure. The failure mileage was 17,000 and current mileage was 25,000.

I recently leased a new 2007 Jeep Grand Cherokee 3. 7 l , 6 cylinders. This was the second time in less than a month that the vehicle stalled while driving at highway speed 50 mph) and local speed 30 mph. The vehicle suddenly lost power and could not be driven at more than 20 mph, and the indicator gauges seem ed stuck in place. Also, the vehicle shut off when making a sharp turn into a parking space at work. The first incident occurred on a major highway in new york city ,and my fear was that another vehicle would rear end my vehicle. We had the vehicle towed to the original purchasing location at additional costs to us, and they stated that the problem was related to the shift controller, transmission not sending the proper signal for it to shift properly. They told us they would replace the solenoid, and it should be fine. This was less than a month ago, and now my wife was unwilling to drive the vehicle for fear of being stuck in traffic or being involved in an accident. I will be taking the vehicle back to the dealer on 7/9/07. Any additional information you could provide to address this problem was greatly appreciated. I will also contact daimler/Chrysler corporate headquarters in the morning.

Problem. . . Driving down the road or stopped at light or in the middle of a turn or on expressway. . . It would shut off without warning, sometime it would restart immediately, sometimes not!!!. . . Extremely dangerous situations developed, which I was lucky!!! 1996 Jeep Grand Cherokee, 4. 0 , 6 cyl. . . . Spent 6 months doing repairs/ replacement parts and many ,many dollars spent tracking down part after part. Using diagnostics machine to determine faulty part. . . Problem was the power control module ( pcm or ecu same part) was defective and either was misreading codes or giving out bad codes to parts (like to the crank shaft position sensor or the coil, or the 01 or 02 ox sensors or it goes on and on and on). Not sure how it works but you get my drift. Since signing up with cnet. Com, have found many people across America with the same issue on Jeep with different years (1994/2000) and models. To search. . . Look up Jeep stalls or Jeep fixed and you will see other topics and forums around that topic and you will also see where the manufacture doesn't know how to address the problem either. Another possible recall issue is the screws that hold the pcm might be too long and are grounding out the unit after paint wears off on firewall. . . Important to read all articles and different forums!!! . . . Is a must lastly. . . Instead of replacing pcm's, is it possible to have the pcm re flashed under recall??? I'm stretching, but maybe electrical power storms and rain is causing parts to defect??? lastly. . . Jeep parts consists of module power units that work or don't work but the pcm reads the codes and adjusts the workable of the motor. . . Another issue is that there are several issues that will shut down the motor besides the fore mentioned parts. . . Ie. . . Asd relay, the security system, door locks, steering column, the electronic key, the back windshield wiper. . .

Our 2005 Jeep Grand Cherokee limited gets stuck in 3rd gea and will not shift. It has 12,000 miles and has been in the shop 4 times for the same problem. It is very dangerous because the car will not accelerate in an intersetion and cannot move out of the way of traffic on the highway. The local Chrysler service manger in san rafael has told us that he cannot solve the problem and that the Chrysler regional manager has not responed to him or to us. The folks at Chrysler's 800 numer has told us that they cannot help us and referred us to the dealer.

The cooling fan blade just broke while stopped at a light. It made the car thump I thought someone hit us but the fan blades broke the fan shrode and put dents all in the radiator and broke the fan guard. This vechile has had many of the same problems due to the electrical system. We lease the Jeep and have put $$$ in it because they would not take it back as a lemon with in the 2 years. I still hear a beep coming from under the dash that Jeep never found the problem or fixed it. I just had the fan relay changed because it went out. With in the first 2 years I had it in the shop for a variety of electrical problems I have all the paper work. I am afraid the Jeep will catch on fire or cause an accident. I've also checked many other things that were issues with the Jeep. Leaking shocks and transmission pan and emissions is now leaking. The check engine light stays on and every time I get it checked it's a different problem. I'm out of my warranty now but there have been so many different things wrong. The dealer replaced 2 of 4 leaking shocks they left the transmission pan loose when they replaced a part in the transmission. This Jeep is unsafe for the road it has lost power in the past while traveling so they replaced the battery twice with in a month.

Without warning the vehicle shut down. This happened at any speed and any weather. Dealer said it was the power control module (pcm), and the part was on back order. Manufacturer said they couldn't do anything to speed up the process and were trying to get the parts to the dealer as quick as possible. The consumer was on waiting list for part. The consumer was concerned about family when driving and car shuts off. The consumer said car takes about 5 minutes f to start back up, sometimes longer. Replacement of part was not included in any maintenance schedule.

Incident 1, on Saturday February 5, 2005 while maneuvering into a space in a parking lot I shifted into reverse with my foot on the brake suddenly the car, 2004, Jeep, Grand Cherokee lurched backward. I pressed more firmly on the brake pedal and car jerked. Then, the engine revved higher, causing the car to hurtle toward cars in the row behind. Only by standing on the brake pedal did the vehicle stop, but just inches from a car behind us. Dealer's mechanic subsequently could find nothing wrong ,and could not duplicate the event. Incident 2 occurred on Wednesday April 20, 2005. While braking gently when approaching a red traffic light the engine suddenly started revving quickly. I braked harder, but the engine revved higher, overcoming the braking effort I again stood on the brake, bringing the car to a halt only a few feet from a car waiting at the light. Examination of the brake pedal at this time showed that my foot was only on the brake pedal, and not near the accelerator pedal, and that nothing was pressing on the accelerator pedal.
