Transmission Solenoid problems of the 2007 Jeep Grand Cherokee

It usually takes a good 10 to 15 minutes to start sometimes then when I do get it started I have the same issues that I have read about on this website and many other websites. The car will not go over 20 miles per hour and you have to pull off the road, turn off the vehicle, wait and turn it back on. It is almost like the Jeep has to be reset. I have talked with several people and had the codes ran. It keeps coming up that it is the solenoid and starter. I have read on many blogs about the same issue that the solenoid wires are not protected from rain water in this vehicle and it causes them to corrode or go bad all together. This is an issue that needs to be recalled. If they know that the wires are not protected from rain water then there needs to be some type of protection that they can put over them or install a different kind of wire. This is costing people hundreds of dollars to repair something that should have never been an issue. Also this is a safety hazard because when we pull out on the road we expect our vehicle to excel properly and go over 20 miles per hour.

I have two problems with the vehicle that make it unsafe to drive. The first is that the engine randomly stalls. Most of the time it stalls when the vehicle is stopped. Sometimes it stalls at very slow speeds. When stopped, sometimes I hear a "thunk" right before it stalls like it was trying to go into gear. It has done this running in park and when the brake is pressed while in drive. It has stalled on me in busy intersections putting me in unsafe situations. Turning the key all the way off and back on will restart it. The second issue is that the transmission randomly gets stuck in 4th gear. It happens most often when a lot of power has been applied from stop. But it also happens randomly. When it occurs, I pull over and stop the engine turning the key all the way off. Usually when I restart it will go back to drive and all the gears in the transmission function normally. The issue is so chronic now with the transmission that it immediately goes into 4th and the vehicle is not drivable. It is at the dealer now. The dealer pulled codes and recommends replacing the transmission solenoid pack. This part is currently on national backorder and there is no eta of when the part will be available to the dealer. Also there is no guarantee that this part will fix the transmission problem. If it doesn't, the vehicle will require a new transmission. They are not even looking at the stalling problem until the transmission problem is resolved. The stalling problem is very serious and I cannot confidently use the vehicle without fearing putting children in an unsafe situation. There should be a safety recall by Chrysler on these vehicles.

I bought this Jeep on 9/20/2013. The truck is equipped with the 5. 7 l hemi engine. Over the first 50 days and 1,157 miles of ownership I have encountered 18 episodes of the vehicle stalling, with 14 of those stalls occurring on major highways in traffic. The stalls occur with no warning. The vehicle immediately decelerates to a stop and I am left with no power, no steering and no brakes. One dealership blamed it on a bad battery. The dealership which sold me the Jeep diagnosed the problem as a m. A. P. Sensor, which they replaced. That did not correct the problem as the stalling problem continues to occur. The most recent was on 11/9/2013 while driving in the center lane of the PA turnpike at 65 mph. The Jeep stalled and came to a stop, with a semi tractor-trailer behind me. I have no idea how that truck driver was able to swerve in time to miss me. Mechanics and on-line forums identify possible causes for the stalling as 1. A defective (ecm) electronic control modules; 2. Shorts in the wiring harness; 3. Sparks plugs; 4. Egr valve; 5. Ignition coil; 6. Pcv valve; 7. Transmission solenoid pack. There are no diagnostic codes stored in the obd-ii system. One school of thought is that 2007 Jeep Grand Cherokee and commanders equipped with the 5. 7 l hemi engine are extremely sensitive to radio frequency interference from the waste spark on the coil. As other complaints have noted, this is an obvious and persistent problem with Jeeps equipped with the hemi engine, and Chrysler has turned a deaf ear to the complaints. Perhaps they are waiting for the fatalities to occur. Why NHTSA hasn't done more to order a recall is beyond my comprehension. The problem has been reported on for years with no action taken by Chrysler. This Jeep is, for lack of a better word, a deathtrap. At best it cannot be trusted, it is unsafe and unreliable. At worst it is an accident waiting to happen!.

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.
