Jeep Grand Cherokee owners have reported 47 problems related to automatic transmission control module (under the power train category).
Vehicle started to jerk/hard shift and slip when shifting from 1-2 and 2-3 while driving on a city street. I took the vehicle into the dealer who replaced the valve body, ran the flash software update and reprogrammed the pcm. The dealer test drove the vehicle and indicated that the "trans shifts very smooth now". 20 miles later while I was driving the vehicle on city streets it began to clunk and jerk when deceleration at 30 mph and then again at 8 mph; much worse than before during acceleration. The vehicle also now lunges forwards and shakes when you come to a stop at a light/stop signs with your foot on the brake. I took the vehicle right back to the dealer who has ordered a new transmission. The vehicle only has 6500 miles on it. This vehicle is very unsafe with all the jerking and clunking and control issues. It appears these vehicles have transmission issues with no "fix" available; so I anticipate the same problem to occur when I get the vehicle back from the dealership with the new transmission.

I would like to know why Jeep/Chrysler has not done any recalls or fixes involving the powertrain control module (pcm) since it is a known issue with Grand Cherokees?!!! instead they want customers to go out and spend approximately $200+ for a new one and even more $$ to have dealer install it. I love my Jeep don't get me wrong, but Jeep dropped the ball big on this one. Just about as bad as the gas tank issue.

Engine stall/shut off on a highway at 70 miles/hr in center lane of a five lane interstate highway with plenty of gas in the tank. Has happened three times on different days. I'm original owner. Heavy failure analysis done. Allege that Jeep cut corners that risk driver safety. They used and may still be using cheap chinese microprocessor chips in their program control modules (pcm). Fred bailey fatal accident is telling. His Jeep shut down on a bridge. Plenty of gas in the tank. Tractor trailer plows into the back of this Jeep (like mine). The gas tank explodes and he dies. .

My Jeep Grand Cherokee has been sputtering, stalling when stopped and when driving, backfires blown apart 2 mufflers. It will not show a check light or give an error code when hooked up to a computer. Have researched online and found several people with same issue. Have done as they have and replaced nearly every sensor. Have yet to replace pcm/ecm. Don't know if this will fix due to some online have and still having the same issue. Like the people online I have taken it to different mechanics, none of which could duplicate or find a problem. Surprised with as many people having this issue Jeep hasn't resolved this. I think dealerships are aware of this issue because some people online have traded their Jeeps in and gotten very little towards trade-in.
Bought new in April 2013. Since then, Jeep has been in dealers service dept for many electrical problems, transmission problems, down loads to control modules and front and rear bumpers just falling off. Radio was replaced, wiring harness replaced, many control modulars replaced, generator and battery replaced and the dealer even added an extra negative wire to the Jeep to stop the exterior and interior lights from just turning off and on, altering the Jeeps design. My Jeep then began turning on and off certain controls, like the wipers would just come on and off, the radio would go up and down in sound then the whole screen would go black, turning off on its own, dealer had to replace the entire radio system. Recent repairs were the transmission, which have been an ongoing problem within month of purchase. The Jeep would not go higher the 2nd gear. Dealer had to remove certain codes, replace with new codes and reprogram the tcm control module. This has been done many times. Just last month, the front and rear bumpers just began to fall apart. Dealer had to send Jeep to a body shop for repairs. The Jeep is in mint condition and aways has. It's service record is proof of proper mainteance on schedule. On one occasion after the dealer attemptedto finx the lights from going out and had the Jeep for sevral weeks, the dealer told me they go the lights to at least not go out but it still has a slight flicker. When I told the dealership that's not fixed right, the dealer told me that they considered the repairs commercially acceptable. It's been almost a year since I hired an attorney to address this under the lemon law but Chrysler continues to drag this issue out without addressing the safety issues my family continues to endure on a daily basis . Asking the attorney to become more involved, I was told they have to do what the law allows.
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?.

The check engine light would come on and go off. . I was driving around 60 mph the car shifted into neutral and lost power. . . I was able to steer to the side of the road but I was in three lanes wide of traffic on the highway and had I not been in the lane closed to the side of the road I could have been badly injured. Within the time frame of three weeks it happened 4 times. . . All when I was driving highway speeds except once the car shifted into neutral on its own and powered down when I was at a stop sign in town. The check engine lights comes and goes so fast by the time I can get to a repair shop and have it scanned its usually off. I was able to scan it once and it read a code for "transmission control module". . . The car runs great but I don't understand why it just powers down. How many people have to get injured from this failure before someone fixes it! this is absurd!.
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).
Was going down interstate 40 coming from little rock ark. Jeep started to slow down pressed on gas would not speed up. There are so many eighteen wheelers on that interstate. I managed to pull over. Started to shifted from park to drive and drive kicked in. I had two children in the Jeep with me . I can not even think about what might have happen if one of those trucks had hit me in the rear. This is a 2006 Jeep Grand Cherokee laredo. I have looked on line for recall there was a recall on the 2008 models . The transmission control module . I have been told that is the problem with my Jeep. When I made in home this happened again coming down my street in halls TN. Got to my drive stop pulling. Put in park back to drive made in driveway. I have seen on line this is a problem with lots of Jeeps not only mine. Please fix this problem before someone get hurt or dies. What does it take!!!!!!! help!.
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. .

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.

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.
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].
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.
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 !.
