I do not remember exactly when the problem started, but while driving at night, my lights started flickering and then went out all together. I thought it happened when I turned my signal lights on, but I am not sure if this is the cause. I took it to the Jeep dealer and they could not find anything. Every now and then, I have the same issue, but nothing can be found. This is very dangerous for me and it terrifies me that someone will think I am flashing them and become angry. There is obviously something wrong if there are so many with this type of problem, but nothing is being done about it. I purchased as a one person lease vehicle from a dealership and within a year had to have my transmission replaced. I could not enter transmission in the parts section.

The Grand Cherokee stalled at a light on a hill. Restarted it and but it back in drive but vehicle continued to roll back almost rolling into car behind. Stalled 4 more times but in parking lots and non busy roads. Took it back to dealer where they updated software on computer and said it was fixed. Then stalled on a busy highway and was almost rear ended because vehicle stalled and wouldn't go into gear. Then parked it in parking lot and it stalled in park.

While driving my vehicle suddenly shifted gears and coasted as if it were in neutral while rpms shot up to 3,000. It then suddenly lunged forward and picked up speed. The check engine light came on. After a day or so, the light would go off. Within the time frame of approx 3 weeks, this had occurred at least 3 times. It was very scary to have it change gears and not be able to maintain speed and suddenly speed up again while traveling with vehicles in front of me and behind me. You essentially have no control of the vehicle in that moment, nor do you have any warning that it is about to happen. Drivers around you also have no warning that your car will suddenly slow down or lunge forward. Took it to the dealership to be looked at. Was told that it was my electronic shifter module and had it replaced. Although I have a power train warranty, it was not covered and had to pay over $900. Did research online and came across numerous others with the same issue. I feel that if this critical part fails on so many vehicles it should be made a recall. When this part fails, it has the potential to cause many accidents.

Grand Cherokee 6-cyl

  • 135,000 miles
My vehicle started originally slowing down like it slipped out of gear. I was told I needed a new transmission but when I replaced it I still had the same exact problem with the vehicle staying in limp mode and check engine light on, RPM running high and not going into overdrive. The transmission is not shifting correctly after spending over $1500 on it. From my research I have arrived at the esm to be causing the problem with the vehicle not indicating what gear for the transmission to shift into. I have called the Jeep corporate office and even though they know that the transmission needed a repair when I first bought it with 17,000 miles on it they still did not feel they were responsible for my transmission problems. To me that are just avoiding the fact that this is a manufacture issue with either poor design, construction or quality of parts. I had a 1994 amigo that I put 280,000 miles on and I never once had any type of transmission issue. This is a 2006 vehicle this is the poorest experience I have ever had with a vehicle.

I had my check engine light diagnosed and found to be the esm shifter, an electronic device that connects the gear shifter to the transmission. It was said to me that this helps regulate that the transmission stays in the correct gear while driving. I have found that the transmission sticks in a certain gear even though it is not the correct gear I am driving in. I have found that I have had to pull over, put the vehicle and park so that it clears before going back in gear. I have also found that that process does not always work, when that has not worked, I would have to turn the vehicle off and back on for it to shift properly. I also had an incident that while using cruise control I was going up a hill so the cruise control kicked in to give the extra boost but it did not shift back down. I was quickly accelerating (almost to 90 in about 5 seconds) and being close to reaching 5rpms I had to turn off cruise control and shift into neutral for it to stop accelerating. Due to the extended warranty I purchased it was not covered. I have talked to a few mechanics and they all have said they have replaced multiple recently. When talking to Jeep headquarters, they stated that it has not been reported as a defective item. I was advised to contact NHTSA to report this in hopes that other have done so so that Jeep is required to make this a recall item. From what I have heard, it has been a fairly common item that needs replacing.

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.

While accelerating attempting to merge onto highway vehicle loses all power and transmissions seems to disengage and only coasts. Car acts like if I shifted into neutral but gear selected is still drive. Check engine light illuminates and engine responds to acceleration but no movement is given by transmission. RPM gauge goes all the way down to idle. Had to pull over the side of the road place in park, shut engine off and restart the vehicle then continue. This is a very dangerous and frightening situation, all power is lost and no control of acceleration is given. This is the 5th time in a year time span, this has happened. Started at about 50000 miles. This has almost caused rear end collisions as well, please look into this matter. I cannot imagine what other less skilled drivers do especially carrying children or pets very dangerous, needs a recall or sb.

Transmission disengages at speed from drive to neutral. Shift lever and indicator remain in drive even though vehicle loses motive power. I thought we were going to get rear ended. I had to pull over to the shoulder and restart the engine to put it back in drive. This problem has occurred three times previously. After checking all the blogs, I see that the switch contacts in the esm (electronic shift module) are prone to failure. The esm/shifter bezel is a $795 part from Chrysler.

At approximately 78K miles, vehicle would occasionally start and the only system that was operational was the radio. I cleaned and inspected all connectors that I could access, and problem appeared to go away. Then just after the warranty expired (80K miles) intermittent electrical issues have begun to appear. The transmission sometimes "sticks" in 3rd gear, the windshield wipers fail to function and when I attempt to turn them on it crashes the powertrain control module which then begins running random system errors, and the headlights sometimes turn off or fail to come on.

While driving on the highway, my 2006 Jeep Grand Cherokee Laredo, jerked violently out of gear (almost into neutral?) and the engine light came on. The gear lights lit up and I had to manually shift it back into automatic. The dealership scanned the code & determined that it was a bad shifter control module. They said I could continue to drive it for a while but it would eventually need replaced. Estimated cost for part $747(excluding $78 in labor). Drove it but realized that it was happening more frequently, many times on the highways traveling at fast speeds. Almost wrecked several times because the part malfunctioned when trying to slow down when the roads were snow covered & icy. This is a serious & potentially fatal safety problem for myself & others on the road that requires immediate attention. I am uncertain as to why Chrysler has not recalled this part or atleast looked into it. I reported it to Chrysler only to find out that they had no knowledge of the complaint. "? there are numerous complaints from other owners that have had the same problem, yet no actions have been taken to remedy the issue. Does there need to be a death to obtain a recall" I am certain that I will purchase a vehicle from General Motors in the future if there is no corrective action taken.

When driving the lights around the gear indicators will circle all the gears and vehicle drops into what feels like neutral and loses power. Then it will randomly drop back into drive. Happened a couple of times then check engine light came on. Code given was loose ground wire in tranny. Dealer fixed. 1 week later happened again and check light came on again. Dealer got same ground wire code, took apart again and wire was fine. Reset light. Still having same problem with shifting and has happened when just engaging to leave out of parking lot then 3 times on hwy at 55 mph. Very scary as don't know if going to go back into gear or power loss will cause someone to rear end you at high rate of speed. Can't always find a place to pull over and re-engage gears. Check engine light came on again today taking it back in for review. Why hasn't there been an investigation or a recall" does there have to be a fatal accident to get attention to this dangerous matter" I love my Jeep but not enough to die for it!
