Grand Cherokee 8-cyl

  • 129,000 miles


Once again as I was driving my vehicle shut down (jerked real hard) and I lost all driving capability etc power steering, speed control..... I was driving on the freeway when my Jeep shut down it was during morning rush hour traffic. It was hard for me to glide over to the shoulder when everyone around you is going 60 mph and you have no power steering. When I was able to get to the shoulder I placed the Jeep in park and turned the vehicle off and removed the key and put the key back in and it started right up. This has been happening everyday now and why searching the internet I've ran across on here and elsewhere that I am not the only one having problems like this with my year and make. It is really dangerous and im surprised there hasn't been a recall yet or a terrible possible fatal accident due to the vehicle being non responsive in fast heavy traffic.

Started with traction control light flashing, then it slowed vehicle felt like brakes were on, gave it more gas and got no speed increase, pressed on the brake and then it seemed to surge and speed up on its own. This was unexpected acceleration &could have lost control. After this! it went back to normal driving. Next day took a 110 mile trip traveling 70 mph on highway no issues until I arrived at destination pulled into driveway and put in park and several warning lights came on ABS, esp, bas, &traction control light flashing & service 4 wheel drive... I had no problems until I stopped... when I started up to return home all the above lights stayed on backed up out of driveway, when I put it in drive and gave it gas it started to make a bad grinding sound like metal on metal a clunking sound and did no¿T respond to fuel peddle. I increased speed then I felt it release like park brake being released... it drove normal back home dash lights still on, ... 110 mile trip doing 70 most of the way... at home I used the built in vehicle scanner and got code U1417 which indicates front left wheel sensor... I replaced both sides same grinding sound, replaced the 2 back sensor...¦ now I have no lights on dash and no grinding clunking sounds no sounds at all. But when I drive I get the traction control light flashing giving it gas I can no¿T accelerate above 25 mph, seems to release at lower speeds below 25mph but it feels like the brakes are on and something it decreasing engine power... this is a dangerous problem! when I pulled unto traffic and I could no¿T get up to speed I almost got into a broadside accident... I thought I had fixed the problem tested it in my driveway no dash lights on, and no grinding or clunking sound¦ so what is it now?... is it some traction control problem seems to be a fathom problem a lot of Jeep owners are having!!

I was driving my 2007 Grand Cherokee overland 5.7L hemi and the truck just cuts off with no warning and then all the warning lights came on and car stopped in the middle of the road during morning rush hour traffic. Car restarted after a few tries and the key was removed from the ignition. As I see this is an on going issue with the 5.7L hemi Jeep Grand Cherokee overland's and there has been no resolution to this problem. It can cause a major accident and a huge lawsuit against Jeep. This should be seriously looked into an a recall should be done for all the other Jeep owners that have this same problem all over the untied states.

As I was driving my car jerked real hard and all my dash lights came on and my ability to drive my car was useless. My Jeep slowed down on the freeway during morning rush hour traffic almost causing several accidents. As I was trying to restart my Jeep it just keep making a clicking noise and wouldn't stop. I had to pull the key from the ignition and reinsert the key and try to start the Jeep. After 3 tries it started and I went to drive off and as I was accelerating my Jeep did it again finally it stayed on and I was able to drive to a safe location. My Jeep sounded real strange not like normal. This is the 5 or 6th time this has happened since I had my Jeep not even a year to date.

The first incident happened when my Jeep Grand Cherokee unknowingly shifted into neutral while driving down my neighborhood road. I was not aware of this until I tried to increase my speed and was not able to. I then had to turn off the car and turn it back on. This has happened three times since 2011.

Grand Cherokee 6-cyl

  • 1,186 miles


While driving, the prndl had lit boxes around all the letters, and dash indicators all lit up, and Jeep lost power as if stalling. It then "went" back into drive on its own. This happened over eleven times, with mileage starting at 1,186, and most recently at 52,536. Dates of repair incidents are : 2/12/07, 12/31/07, 1/10/08, 9/22/08, 1/5/09, 6/9/09, 6/18/12, 10/19/12, 12/26/12, 3/8/13, 3/22/13. My Jeep is a 2007, averaging 8,756 miles per year. I bought it new and I take very good care of all maintenance right away - oil changes, filters, tire rotation, etc.! each time it was brought to the dealer for "repair", they either couldn't find the problem, or replaced : shifter module (twice), transmission wiring harness (three times) and suggested a new battery (we replaced that also), and transmission plug and seal. There were also numerous "software and anti-theft updates. In addition to these, I replaced the driver's side window regulator twice. Now, they want to replace the "transmission temp circ." And esm module - for another $1,500. All this in 52,536 miles and 6 years !!! I firmly believe there are serious manufacturer defects with this vehicle. My biggest concern is the safety of this Jeep is unpredictable. I never know, even after all the "repairs and replacements", if it will suddenly lose power and I might be in danger (traffic, intersection, etc.). how in the world could Chrysler deny this problem" it needs to be resolved at the source, they are responsible for the safety of their vehicles !!!! there are many reports of this same issue from numerous 2007 Jeep owners - where is the recall ??"!!!!

Grand Cherokee 8-cyl

  • 60,980 miles
I bought my 2007 Jeep Grand Cherokee overland in June of 2011 with 52095 miles on it. In March of 2012, I experienced the first of many stalls happen to the Jeep with 60,980 miles on it. It has random, unpredictable stall outs that happened through out the year. It seems to stall when accelerating however not all the time. It's stalled while driving on the highway (mass pike or rt. 9) and on side roads. I have not observed any precursors to the stalling. When it stalls, it bucks and then the Jeep does not accelerate however the lights come on, just like what happens when a manual vehicle is stalled. These types of stall outs I experience do not happen all the time. What happens sometimes is the Jeep will buck, like it's going to stall, but it doesn't after slamming on the accelerator. After a stall out, I am able to restart the Jeep after a minute or two. The engine light has never come on, just the oil light. This Jeep has had the ignition connector and software replaced twice in over a period of two years. It's been replaced because of a stored code: Fcmcgw B2185. There are two other codes stored in the computer: PCM P0884 and ABS C12K. I have taken the Jeep to dan's Jeep in westborough, MA since the first stall out to the present. The recent stall out was Friday, January 11th. This stall out was a little different because "programming assess" (something like that) appeared on the dash with a blinking red light. Everytime I bring the Jeep to dan's, they give me the same response to the problem...they don't' know why this is happening and I can start replacing parts to see if it corrects the problem. I do not have the finances to just keep replaces parts to see if it'll correct this serious and unsafe problem with the Jeep and Chrysler has not reported how to fix this or made the step forward to fix it.

Grand Cherokee 6-cyl

  • 57,000 miles
I was driving 65 miles per hour on the expressway, when suddenly, my Jeep began to decelerate until it reached about 40 miles per hour, even though I maintained constant pressure on the accelerator pedal. It felt like I had no control over the speed of the vehicle. Traffic was light so I coasted, and pressed the pedal a little harder, until eventually, the SUV lurched and then started to accelerate. About 3 minutes later, the same thing happened again while I was still driving on the expressway. The vehicle decelerate to 35 while it seemed that I could not control the speed, and then accelerated again. After the acceleration dropped and then increased the second time, I was able to maintain 65 miles per hour until I exited the expressway 15 miles later near my home. Driving a vehicle under these conditions is a horrible feeling! I was so afraid that a car or truck moving at the normal speed would crash into me. If the traffic had been heavier, I would have had to pull over to the side of the highway, which would have been even more terrifying, because it was dark outside, and I had no idea what was going on or how long I would be stranded. We just had the SUV's engine tuned one month ago at the dealer's service center, and we also had the oil changed at the same time. There haven't been any episodes like this until now. I'm actually afraid to drive the Jeep again!

This is a continuing issue. The speed will suddenly decrease to 30 miles per hour without any action on drivers part. This is dangerous, especially on busy roads. We were told it was the front control module but after reading reviews it doesn't solve the problem. Chrysler should be held responsible to identify the problem, then issue a recall. They are not interested in doing anything. We bailed them out?

The vehicle will stall out when you are trying to accelerate, even with the gas pedal to the floor the rpms will shoot up but the vehicle will not move forward. If you stop and put the car in neutral it will sometimes fix itself but not always and this is not a good option to resort to in the middle of an intersection. This vehicle will also downshift on its own while you are driving at a high speed slowing your car without warning. Very dangerous if driving on the interstate with other vehicles around. Was told replacing the electronic shift module (at $1100) may possibly fix the problem but the dealership was not sure that this would remedy the issue.

  • 41,000 miles
Shortly after changing the spark plugs in my wife's 2007 Grand Cherokee overland the vehicle would stall on deceleration. I thought it might be an isolated incident, but the stalling continued frequently. The engine completely shuts down and the vehicle must be stopped or put in neutral while coasting to be restarted. After conducting some internet research I found this to be a common problem with the 2007 Grand Cherokee with hemi's. I was amazed at the number of occurrences of this happening among this vehicle. There are Jeep forums (www.jeepforum.com/forum/F67/2007-Jeep-grand-Cherokee-overland-stalling-problem-1147825/) that discuss this issue in depth. The vehicle stalls less frequently than it did when I first changed the spark plugs, but it still happens. The most recent occurrence was on November 1, 2013 when my wife was picking my son up from school. Chrysler corporation fails to take a stance on the problem denying that the problem exist. I have spoke to my local dealer's service department about the problem and they denied any knowledge of it. I would sale the vehicle, but in good conscience I could not do that to another individual. Several dealerships have replaced the upper and lower wiring harnesses on several vehicles and this seems to have resolved the problem. Again to restate the problem it seems to occur after the spark plugs are changed in the vehicles. This would lead one to believe that disturbing the position of the wiring harness effects the vehicle. Chrysler no longer manufacturers that wiring harness, as they are on the third version of it. This in itself would lead you to believe that Chrysler has some knowledge of a problem, but will not issue a recall or take any official position. My main concern is for my wife and children's safety while riding in this vehicle. I ask that you please take an in-depth look into this situation.

My wife was driving our vehicle down the road and not even 2 miles the vehicle would not let her go faster than 30 mph and the vehicle would not shift out of gear. The check engine light came on and we took it to get an obii scan. The code that was prompted was an esm malfunction or transmission speed sensor. I am having so much trouble finding a speed sensor that is available and high priced. The esm is not hardly available anywhere except at a dealer. I have been reading tonight online and there have been many cases of these problems happening with some more severe incidents. If so many people are having shifting, esm and speed sensor issues, shouldn't this issue be addressed. I am pretty sure this isn't the first issue or complaint. I have a 3 year old and a vehicle that was named a smart buy by consumer guide automotive in 2006 and the redefining vehicle of Jeep flagship is a hazard and unsafe for my family. I will not be recommending a Jeep of this year to anyone. I hope you take this incident with thoughtful consideration and start thinking about your consumers safety.

Jeep looses power, will not accelerate over 30 mph. This has not happen on a highway yet (luckily) only in-town driving. No error codes present in dtc report or from a diagnostic that cost $90 something needs to be done about this before an accident results in a fatality. There seems to me many instances like this on these boards. This is the first investment of a 'real' vehicle that I've had. To pay money for something dependable is the goal. Currently this vehicle is not dependable, let alone safe.

My wife was driving and just about to get onto the interstate and with no warning, she couldn't accelerate past 25-30mph. Luckily she was able to pull to the side of the road quickly without an issue and turned the car off, waited a minute and started the Jeep up again and was then able to accelerate. When talking to the dealer, they have never heard of this problem before. When Jeep was checked at a local dealer, they pulled error codes that pointed to the transmission speed sensor. Only about $700 to replace that with labor!! the sensors are all part of the circuit board and thus need to dismantle the transmission to replace the sensors. Then I get on this site and see all the complaints with the same issue. This weekend I'm going car searching to get rid of this thing.

The contact owns a 2007 Jeep Grand Cherokee. While driving approximately 45 mph, the vehicle suddenly began to decelerate independently while the contact was depressing the accelerator pedal. The vehicle then accelerated suddenly and rapidly. The vehicle was taken to the dealer for diagnostic testing. The technician was unable to diagnose the failure. The vehicle was not repaired. The VIN was not available. The approximate failure mileage was 64,000.

  • 29,000 miles
While pulling out of a gas station into heavy traffic, I began accelerating to the speed limit of 45 mph. I was accelerating rapidly as traffic was coming quickly from behind. The Jeep stopped accelerating and the instrument panel showed all of the drive letters with boxes around them. The Jeep would not accelerate for over 20 seconds, causing me to rapidly pull off of the road to avoid traffic behind me. The dealer found a faulty electronic shift module and replaced it. The vehicle has worked well until 2/15/12. At 70,000 miles, the dealer installed module has failed again. Once more this happened when entering a heavy traffic roadway. There have been numerous reports throughout the internet of people experiencing this same issue. In my case, both failures resulted in me having to take evasive action to avoid a collision. I find it hard to believe that this seemingly common problem has not been identified as the tremendous safety problem it.

  • 79,400 miles
I purchased this vehicle on December 14, 2011. About three weeks later in a parking lot, we noticed the vehicle would not accelerate even though the accelerator pedal was pushed virtually all the way down. A few days later the engine warning light came on. Then the lack of acceleration happened on the interstate. My mechanic cleared the engine warning light but it came back on a few days later. I did a lot of research and it appears this is a common problem on Jeep vehicles. The problem is a failure of the electronic shift module. It if very expensive to have replaced. My local dealership charged me $924 plus tax. As many comments as I have seen on this and the fact that lack of acceleration is a safety issue, Jeep should not hesitate in issuing a recall.

  • 50,000 miles
I was not able to control the speed of my vehicle during acceleration. When I accelerated, the car would significantly decrease in speed almost as if it was running in low gear. It has happened at least 4 times since I purchased the car brand new. Today at 60,000 mi it happened twice. A few months ago I tried to merge onto the freeway and lost power which was very dangerous and I had to turn on the hazard light and quickly pull over to the shoulder. I noticed all of the lights [ P, R, N, D] on the dash board were on. The car seems to reset when I shift to park or turn the ignition off and then on. The problem happens intermittently. I believe that this could be a manufacture defect. I took the car to 2 authorized Jeep Chrysler dealerships to get it checked out. One dealership told me that they've never heard of the problem, another one found a code U0404 but didn't know what it meant. I find this extremely dangerous and could be a manufacture defect.
