Also please check out the statistics and reliability analysis of Jeep Grand Cherokee based on all problems reported for the Grand Cherokee.
While driving the vehicle I receive a message on the info center displaying "transmission over temp" the fan kicks on high and the vehicle will not go faster than 25mph. I have to pull over, turn the vehicle off, wait 30 seconds, turn it back on and it goes away. Had my vehicle at the transmission shop and had it thoroughly looked through and the pcm is to blame. It is very common on these vehicles. I feel it is a saftey concern due to the "transmission over temp" displaying every couple of miles as I drive. Calling Chrysler directly to ask of the problem and they were very rude and hung up on me. Not happy!!.

Tl- the contact owns a 2011 Jeep Grand Cherokee overland. The contact stated that the battery warning light illuminated. The vehicle was taken to an independent mechanic who replaced the battery, the alternator assembly and the pcm. The alternator assembly had been extremely warm internally which had affected the pcm. The vehicle had to be turned off during the repair to further diagnose the pcm internal voltage shortage. The dealer fred beans Chrysler Dodge Jeep ram (858 n easton rd, doylestown, PA 18902, (215) 348-7500) was aware that there had been two recalls for NHTSA campaign number: 15v879000 (electrical system), 17v572000 (service brakes, service brakes, hydraulic) and had scheduled an appointment for the recall repairs for may 10, 2018. The manufacturer stated that the vehicle was not included in NHTSA campaign number: 17v435000 (electrical system). The manufacturer was notified of the failures. The approximate failure mileage was 83,000. Dyd.

A week ago my battery light came on in my car on my way home. Luckily I was able to get home before it died. We drove my car to an independent mechanic that we always go to get it diagnosed. My mechanic said I made it just in time because when they went to start my vehicle it was completely dead. They diagnosed that I had a bad battery and replaced it. They also identified that the alternator was bad and said there was a recall on it (I never received a recall notice on this part though). My car was towed to a nearby Chrysler dealership and they completed all the open recalls on it, including the alternator belt. Then my car was towed back to my independent mechanic. After my mechanic ran my car for 20 minutes the car shut off and it was found that the powertrain control module shorted. I immediately called Chrysler customer service to report the issue. It has been over a week and I have spoken to 5 different customer service agents. Every single one has told me something different and a different process I have to follow. My car has been towed back to the dealership and just sitting there. It has been over a week since I have had my car. I just heard from a customer service agent today that the car has to be diagnosed by the dealership and they have to declare that the pcm is not working. I have no idea what will happen after that. I am really trying to get them to pay for this and not go through a reimbursement process because I don't have faith I will actually get reimbursed in the end. I am so disgusted with the treatment Chrysler has given me. They obviously are trying everything to get out of paying this. Well they picked the wrong person to mess with, I will not back down.

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.

The contact owns a 2012 Jeep Grand Cherokee. While the vehicle was parked with the air conditioner and radio still operable, the contact exited the vehicle. Upon returning to the vehicle, he noticed that the air conditioner and radio stopped working, but the windshield wiper blades were moving at slow speed. The contact shifted into drive, but the vehicle was moving slowly and the steering wheel seized. The vehicle was stopped, shifted into park, turned off, and failed to restart. The voltage warning indicator illuminated. The vehicle was towed to an independent mechanic where it was diagnosed with a faulty alternator and battery that needed replacement. The parts were replaced, but the mechanic noticed that the computer was damaged and could not be repaired. The vehicle was towed to another independent mechanic who diagnosed that the pcm needed replacement and there was an alternator recall. The vehicle was not repaired. The contact had the vehicle towed to jt Chrysler Dodge ram of lexington (located at 4838 sunset blvd, lexington, SC 29072 (803) 957-2010) for repairs. The manufacturer was notified of the failure and confirmed that the VIN was not included in NHTSA campaign number: 15v674000 (electrical system). The failure mileage was 113,002.
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.
Tl-the contact owns a 2011 Jeep Grand Cherokee. The contact stated that while driving 60 mph the vehicle shifted into fourth gear independently and stalled after a inclined hill with check engine warning light illuminated. The vehicle was unable to restart. The vehicle was towed to an dealership where it was diagnosed the transmission control module failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and stated a case has been assigned however it was not guarantee due to the vehicle was out of the 36 month warranty. The approximate failure mileage was 90,000.
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. .

Tl-the contact owns a 2014 Jeep cherokee. The contact received notification of NHTSA campaign number: 15v509000 (visibility) however, the part to do the recall repair was unavailable. The contact also stated that while driving the transmission failed to shift. The contact stated that the vehicle would not downshift to the lower gears. The vehicle was taken to the dealer where the transmission control module was reprogrammed, however that failed to fix the issue. The manufacturer was notified of the failure. The approximate failure mileage was 7,000. VIN tool confirms parts not available. Ah.

The vehicle goes into what�s called a �limp mode� which essentially means it has lost communication with the transmission control module and the vehicle will not shift.

The vehicle was not repaired. The failure mileage was 52,000.
The contact owns a 2015 Jeep Grand Cherokee. While driving various speeds, the shifter would erroneously shift out of gear and a hum was present coming from the transmission. Also, the display panel changed from drive and displayed a straight line. The vehicle began to hesitate and reduce speed. After stopping and switching the shifter back to drive, the vehicle operated normally. The vehicle was taken to the dealer where it was diagnosed that there was erratic transmission failure. The pcm, tcm, reh, and ipc were all reprogrammed. After retrieving the vehicle and driving, the vehicle would not accelerate on demand. The manufacturer was not notified of the failure.

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.
