Upon acceleration from stop vehicle will hesitate and lose power. This constitutes a hazard to vehicle and any approaching vehicles during a turn. Inspection indicates that transmission electronic control module is at fault along with a possible transmission sensor failure. The check engine light will come on. Both of these conditions ( power and check engine ) are intermittent, indicating that the module is faulty. There have been many complaints about the transmission ECM on these vehicles. The other complaints have varying symptoms but all go back to the transmission ECM. These unit should be recalled and repaired or replaced at manufacturers cost. This problem exists in many different models and years of vehicles, but always go back to this ECM unit. After investigating this problem I don't feel that the consumer is at fault or causing this to occur. Chrysler modules are and have been faulty in the past. Anecdotal evidence says that other modules in chrysler vehicles have had problems too. Please investigate the chrysler transmission ECM's and have them recalled.
2007 Jeep Grand Cherokee transmission complaints

While I was driving home last night 12/16/11 with my fiancee we stopped at a traffic light, and when the light turned green the jeep started back up fine all except it couldn't go faster than 20 miles per hour. So I put my flashers on and the traffic behind me went around us, then it worked itself out, but did it again when I came to another traffic light. But this time I was able to use my manual shift to help it. No warning lights came on. And I just purchased this jeep 2 days ago. I would like to get this safety issue fixed since I have seen that this is a dangerous and common problem with the other 2007 jeep grand cherokees. I am also a firefighter and I depend on this jeep to get me to fire scenes and other emergency scenes, and I don't want to be in an emergency scene involving me due to the safety issues this jeep is having. Can someone please do a recall and have this issue fixed.
While driving the vehicle loses power no matter how much gas you give it. The engine light comes on and off every few days. All the gear indicator lights are highlighted.
I was driving approximately 40 MPH in the fast lane of a main two-lane residential roadway when the vehicle suddenly jerked violently forward throwing me into the steering wheel and then all acceleration and speed stopped. The steering wheel became abnormally stiff and difficult to turn however I was able to guide the completely stalled and decelerating vehicle to the slow lane and pull-off on the side of the road (with no side lane) with hazards flashing and traffic passing. This was an inherently dangerous condition as the flow of traffic was going approximately 35 - 40 in the fast lane at which time I completely lost power and had limited steering (more like coasting) ability. I was able to turn the engine completely off and restart, however the next day under similar conditions of normal driving conditions the vehicle jerked and stalled again, and restarted after a complete shutdown. This vehicle on the third day post the first incident failed to restart after driving to a local shopping destination and turning the car off to park. I left the vehicle at the location for approximately 4 to 5 hours and retrieved the vehicle upon which it started with a documented call into road side assistance program from jeep. The next day (monday) I drove to an authorized dealer upon which they stated the failure was the electronic shift module (esm) [(not to be confused with the electronic stability control (ESC)] which controls the electronic signals from the computer to the transmission at a personal cost of $820. I believe this represents a known defect as currently 55 out of the 133 complaints listed here are describing a similar series of events and root cause, and would be willing to be involved in a class action law suit against jeep as life, limb and property are at stake.
When you shift from park the prdnl will have a box around each of the letters. When backing up it slams into reverse and then slams into drive and the vehicle will only go 20 MPH no matter how much you step on the gas. This has now happened 5 times and the only way it goes back to normal is to shut off the vehicle and start it back up. I have now seen numerous blogs where this happens at highway speeds, in the middle of intersections and is so dangerous to drive cause you never know when it is going to happen. From what I have read it looks like you have to replace the electronic control module at a cost of almost $800 to just have it go out again later and have the same problem again. This is very dangerous and scary!
While driving the vehicle, had a sudden lose of ability to accelerate, no throttle response, no rpms on the tach, and every gear indicator was illuminated as if in all gears at the same time (park, reverse, neutral, drive). Dealership says its part # 52124137ac that needs to be replaced, and is not covered under any power train warranty, at a cost of $817.00. This problem happened 4 times before I was able to get it in to the local dealership, never on the highway, if it had happened on the highway, im sure I would have been taking a chance with my life.
Owned the 07 jeep for 5 months. Vehicle has been serviced for 2 different incidents. The 1st incident(actually happened several times) is when the vehicle would not shift during acceleration and it would force me to the side of the road where I would have to turn the vehicle on and off until it would run correctly. Was told by dealership service that it was a transmission sensor,had the part replaced-not covered by warranty. Less then 3 weeks later, 2nd incident occurred when I was driving 55mph down the interstate while accelerating to get over to an exit, the vehicle threw itself back into 2nd gear and I was forced to get over into the emergency lane so as not to be struck by oncoming traffic. The jeep had almost come to a complete stop in traffic! Check engine light came on and went off after that. Dealership states the gear ratio and valve cover forced the vehicle into 2nd gear. Very dangerous!
My jeep has experienced three electrical failures which have occurred approximately 6 months apart. For some unknown reason the battery died overnight each time. The second time it happened I purchase a new battery but six months later it drained too. I was able to successfully jump-start the vehicle after each incident. Transmission----I haven't been able to down-shift from drive to a lower gear. This problem began at about 46000 miles. I took it to a repair shop where they diagnosed the problem as defective shifter control. Before I had it repaired (est. $1000) it began functioning normally, that is, until today. I left a parking lot and merged into traffic. Fortunately traffic was light because I couldn't get the jeep to go any faster than 28 MPH. It seemed like the transmission was stuck in first. Also the engine light came on. This is a very serious situation that should not be ignored by the chrysler corp. Or the national highway traffic safety adm..
Tl* the contact owns a 2007 jeep grand cherokee. The contact stated the gear shift module caused the vehicle to lunge forward and backwards. The vehicle would not accelerate over 20 MPH. There was also a warning light illuminated indicating the gear shift had failed. The vehicle was taken to the dealer who replaced the gear shift module. The manufacturer was notified and informed her to file a complaint but offered no other assistance. The failure mileage was 98,300.
On oct.5th as I was merging onto the thruway at 55mph the truck just stopped accelerating in rush hour traffic. I put on my flashers and coasted to the shoulder just barely avoiding being rear ended. This was the second time this has happened with this vehicle. You could press the gas pedal and the RPM's would go sky high but the truck would not move while in drive. I turned the truck off,waited several seconds,started the truck and it moved in drive. I immediately called the dealer and have a oct.7th service call.this was a near death situation the second time due to the rush hour traffic. This vehicle has trouble shifting when started in the morning. After looking into the matter this appears to be a common problem with this model and make. It appears the electronic shift modules need replacing.after reading the numerous similar complaints I thought I would file a complaint before someone gets killed.
Check engine light continues to come on at random. When it does, problems accelerating. Car will not accelerate past 20 or sometimes car "sputters" jerking a lot. Sometimes at red lights, rail road crossings, anything really where the car is stopped, car will not resume driving and car sounds like it is in neutral and I am reving it up. Electronic dash puts a bracket over each gear, p r n d, all at once. When engine light is on it is on for a period of days. When I turn the car on and put it in to drive it makes the most horrible sound as if I backed into a wall and jerks. Sometimes on the highway when the light is on it's as if I smell something burning through my air vents. Everytime I take it to the dealer or any shop just for a diagnosis it's just my luck that the light turns off and they tell me my car is fine. This car needs to be recalled from looking at the complaints!!!
Upon driving on the highway, I felt my vehicle's transmission change gears, which felt like neutral. My car slowed a bit but then sped back up, and then slowed again and sped back up. I then noticed the p, r, n, d were all lit up. I had no control over my vehicle's acceleration when this occurred. After I brought my car to the dealership, I was told the electronic shift module had to be replaced. After replacing it, three months later it occurred again, and was replaced again. Over the last 1.5 years it has occurred randomly, over and over, and now needs to be replaced again. This is a safety issue as the driver has no control over the vehicle's speed. Jeep knows about this issue but refuses to acknowledge that a recall needs to be issued, therefore making their customers continue to pay for the repairs. A recall needs to issued.
Tl* the contact owns a 2007 jeep grand cherokee laredo. While driving 45 MPH, the vehicle stalled without warning. Both the dealer and manufacturer were notified of the failure and the vehicle was taken to a private mechanic for diagnostics. The mechanic found that there was an incorrect gear ratio and advised the contact to take the vehicle to the dealer for repairs. No repairs were performed. The current mileage was 37,600 and the approximate failure mileage was 25,000.
Tl* the contact owns a 2007 jeep grand cherokee 4x4. While driving approximately 55 MPH, the vehicle decelerated and lost power. The contact stated that the vehicle would not accelerate over 20 MPH. The contact shut the vehicle off and was able to restart the vehicle within a few minutes. The failure recurred a second time. The manufacturer was contacted and a complaint was filed. The vehicle was towed to the dealer for diagnostics but was not repaired. The approximate failure mileage was 33,300.
Esm- electronic shift module issue: p, r, n, d, l all light up simultaneously and the car gets confused as to which gear it should be using. Occasionally, the check engine light comes and goes. After reversing, I put it in drive and it shifts roughly. Randomly the car loses power driving down the street. I had the esm replaced and a month later is showing a u404 code.
Vehicle is 2007 jeep grand cherokee and currently has 18300 miles and was purchased new in jan. 2008. Two failure to accelerate problems have occurred. One on 5/31/10 and another on 04/21/11. In both instances the vehicle would not shift into the next gear and the speed could not exceed 30 to 35 MPH even with the accelerator pressed all the way to the floor. The problem occurred without any warning. After the first occurrence the dealer replaced the bezel shift selector. After the second occurrence the dealer could not determine what the problem was. Merging onto a busy freeway where traffic speeds routinely exceed 80mph and not being able to accelerate beyond 30-35 MPH is a serious safety problem which could result in injury or death. The same safety concerns apply if the vehicle suddenly decelerates from 70 to 30 MPH.
The dash indicators for the gear shift will all illuminate at the same time and the vehicle will go into neutral. This has happened three or four times. The last time it occurred while traveling on the expressway, fortunately I was able to get it back in gear after taping the shift lever several times. The vehicle was taken to the dealer and they said they replaced a electronic shift module. They kept the old part that was removed.
When putting transmission into drive, the vehicle will not accelerate, this problem first occurred at approx 31,000 miles. The dealership replaced the shift control module. The problem went away. Then again at 62,000 miles, when pulling into traffic, the vehicle started to accelerate, then lost power. Another vehicle had to swerve to miss me, I would have been hit in the drivers door had he not swerved. My vehicle would not move, after cycling the ignition key , the problem went away, took to dealer they told me that the same shift control module needs to be replaced (again) for 750.00. The vehicle is unsafe to drive and I am shocked that someone has not been killed by this issue as there are hundreds of reports of this on the internet. This is absolutely a manufacturing defect as it has happened on a wide number of identical vehicles with the same repair being performed only to have the problem repeat itself.
Tl* the contact owns a 2007 jeep grand cherokee. The contact stated that the front drive shaft at the transmission failed. The drive shaft hit the ground and the other half of the differential joint caught on fire. There were no injuries and the police were not called. The manufacturer was contacted and sent an investigator to further assess the failure. The contact was awaiting a ruling from the insurance company and the manufacturer. The failure mileage was 58,000.
Vehicle has lost power while driving. You will be crusing along or pulling out into an intersection and you will loose all power. The engine will not rev, no response at all. After waiting for a perion of time, the vehicle starts going again. This happened to me four times, once in the middle of an intersection, four lanes in all directions, and the vehicle just lost all power. Very scary. I took the vehicle to my local garage, and he told me that this was the second jeep to do the same thing. The owner had to have the vehicle towed into the garage, and upon arrival, could find nothing wrong. I had to go to an authorized jeep dealer, and I asked them if they ever heard of this happening, and the reply was, just 3 or 4 times....imaging if this failure happened this often in this small area, how many other vehicles may be having the same problem. The vehicle only had 31000 miles on it, but it was out of warranty for time by 9 months. This is a very dangerous event when you are driving and suddenly loose all power and don't know if or when it is coming back. Chrysler said they do not have a problem. I don't believe them.
2007 jeep grand cherokee laredo, pulling onto highway vehicle experienced loss of power. Prnd on display were all selected and check engine light came on. Was able to pull to side of road , put vehicle into park, cycle vehicle off then back on and power was restored. Since the initial occurrence the event has happened twice more. Scheduled appointment with repair department.
When my 2007 jeep grand cherokee is in drive, there is a loss of power. The check-engine light comes on, and it's as if the car doesn't know whether it's in drive, neutral, reverse, etc. The dealer says I need a electronic shift module to the tune of $600+. After looking into this, I see it is a problem with many jeep grand cherokees. I am looking into getting jeep to take responsibility for the faulty part.
Tl* the contact owns a 2007 jeep grand cherokee. While driving approximately 30 MPH, the vehicle failed to accelerate and all of the warning lights on the dash board were illuminated. The vehicle was taken to the dealer where the technician advised that the shift module would need replacing. The mechanic advised that there was no guarantee that the failure would not recur. The vehicle was not repaired and the failure persisted. The contact stated that the failure would occur most frequently in colder temperatures. The VIN was unavailable. The approximate failure mileage was 53,000.
Jeep grand cherokee 2007, 25,000 miles. Suddenly decelerates and all of the boxes around the gears prnd light up at the same time. I need to pull over, turn the jeep off, then restart to regain normal running. This could be a tragic problem if the jeep were to suddenly decelerate on a highway with a full load of children.
Tl* the contact owns a 2007 jeep grand cherokee. The contact was driving approximately 30 MPH when the vehicle would no longer accelerate and came to a stop. The check engine light was illuminated and the steering wheel became abnormally stiff. The contact was able to move the vehicle to the side of the road and turned the ignition off. When the contact restarted the vehicle, the vehicle jerked but the contact was able to drive the vehicle to his residence. The failure persisted at least sx times and the vehicle was taken to the dealer where the technician advised that the transmission module control would need replacing. The manufacturer was contacted and advised they would work with the dealer in assisting with repairs. The vehicle was not repaired. The approximate failure mileage was 27,600.
I was driving at 70mph on the highway when suddenly the car "jerked" and the speed drastically decreased to 20mph. I was unable to accelerate. The check engine light came on and there was a box around prnd instead of just around drive. I got off the highway as soon as I could and drove to my local mechanic. The same thing happened to me in oct 2009 shortly after I purchased the vehicle, I brought it back to the dealer and it was fixed at that time. Now alittle over one year later the same thing happened. I am lucky that I was traveling when traffic was light or it most certainly would have caused an accident. I spoke with jeep and they were not willing to offer any assistance unless I brought the car back to the dealer in which is was repaired before, I explained that the dealership is one hour away and I would not be driving my vehicle that distance and do not currently have the financial capability to have it towed that distance. They need to issue a recall on this situation.
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.
Jeep accelerates then at about 15-20mph it wont accelerate any more and boxes will appear around the p n r d and then it will all of a sudden jerk forward and the check engine light will go on.
In may 2008, 15308 mi on jeep, slowing for red light, dies, all dash lights com on, no power to steer, no wipers, etc.; starts back on it's own. Took to dealer, no code, no re-act; has happened intermittent since-safety issue in traffic. Now tranny problem, started sept. 2010, 37,600 mi, code 750, changed solenoid pk in tranny, now code for low pressure send circuit, drives a few miles then goes and stays in 4th gear; 3 months and still not drivable. Need recall for esm and tbs before someone gets killed. Chrysler should stand behind their products & be responsible for design and components. This is very disheartening since both my husband and I own a small biz and are struggling just to keep the doors open and now add the expense of diagnosing chrysler's problem is just too much! I warranty my work, wear & tear considered, as should chrysler before someone is hurt or worse- dies trying to get to out of traffic.
Tl* the contact owns a 2007 jeep cherokee. The contact stated that while driving approximately 50 MPH, the shift module suddenly failed by shifting out of gear and the vehicle stalled. The contact was able to restart the vehicle and then drove to the nearest dealer. The dealer inspected the vehicle and informed the contact that he would need to replace the gear shift module. The vehicle was not repaired. The failure mileage was approximately 48,000. The VIN was unavailable.
