After we purchased the Jeep Grand Cherokee it was taken in for a recall for the tcm, to be serviced and have the power steering fluid checked for leaks due to the well being empty. We were then told when we picked up the vehicle and the power steering well was dry that all Jeeps are like that. After questioning that statement the tech went to vehicle and filled the well. After the dealership replaced the part, the vehicle will hold for 2 to 3 seconds then begin to roll back for 10 to 30 feet depending on the grade of the incline when in drive. It is an automatic with the hill start assist which does hold the brakes for the allotted time. The recall was for the vehicle to go into park if the driver takes off his seatbelt and exits the car in gear. That does work. The Jeep will continue to roll until it jerks itself into neutral then stalls the motor, it will continue to roll if the brake is not applied. Chrysler and the dealership continue to say that all vehicles (automatics) will roll back on an incline in drive and not stop until you apply the brake no matter the distance. We have discussed this issue with multiple Chrysler certified mechanics and they have stated that under any circumstance no automatic transmission should roll back more than a foot. The manager of the service department stated that all vehicles roll back no matter the distance. I stated my kia soul does not even move an inch backwards in drive on an incline, he responded with"yes it does". He then stated that "due to the lemon law we can not guess what is wrong, if we are fix it three times you can return the vehicle and the time we have put into your Jeep we are not getting paid for ". He also stated that our Jeep does not idle high enough and can not be adjusted and Chrysler says we are responsible to have control of the vehicle at all times. We don't want to return the Jeep we want it safe.

While driving on freeway, battery warning light lit up, followed by (incorrect) error messages on instrument cluster menu that driver seatbelt was unfastened. All electrical equipment in the vehicle ceased operation, including ac and stereo. I pulled off of freeway and opened hood to find the alternator smoking heavily. This was the exact same failure situation described in Chrysler recall p60, but because my alternator was 180amp instead of 160amp, it was not covered by the p60 recall. The alternator had to be replaced. The alternator failure also resulted in a blown-out pcm, which had to be replaced. This is an extremely dangerous failure that could have caused a car fire, or traffic accident. Chrysler recall p60 should include the 180amp alternators, as well, because they have the same fault and safety issues.

180 amp alternator experienced catastrophic failure causing total loss of all power, battery failure, pcm failure and smoking and burning smell from engine compartment. Experienced loud whinning from alternator while driving immediately prior to failure. Ultimate failure occured as car pulled into parking spot. This is the same issue experienced by 160 amp alternator under recall. It is extremely dangerous and Chrysler/Jeep should be required to fix these issues.

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).

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.
