Five problems related to automatic transmission control module have been reported for the 1996 Jeep Grand Cherokee. The most recently reported issues are listed below.
The inspection recall on my 1996 Jeep Grand Cherokee did nothing to fix the problem with pcm and catalytic converter specified in the defective issue within the recalls issued. This harms the driver, pedestrians, other passengers and motorists. The tech where I went to have recall work performed ordered parts (see attachment), but nothing was installed on my vehicle. Only "inspected. " the tech was told of detailed poor performance and symptoms of a bad pcm. Such as shifting, stalling, fuel economy & hard to start. The Jeep is not operating optimally & this could mean there are. Other problems between different systems. All of these are indications of a faulty pcm. As well as the abs light being on the dashboard. The pcm is a "critical" system & needs to be replaced. I'm requesting that you fix this problem for free, as it is defective and could mingle with other systems and cause a complete vehicle break down. Or refund the cost to me in full, including labor charges, if I replace/repair myself. If this defective part is not fixed, it could result in property damage, in which cdj would be liable for. Please advise as to how you can help enforce the manufacture to fully repair these defective parts & remedy this problem on fixing the faulty pcm & catalytic converter within a recall and possibly the abs system and transmission. The vehicle stalls on highway, in park, on the street, when stopped and then it stalls out and is hard to start. It also has not been able to go in reverse ( back up). Which mean it's not getting proper lubrication. Also, the alarm goes off when using key to gain access. Unhooking battery to reset does not help.
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).
Problem. . . Driving down the road or stopped at light or in the middle of a turn or on expressway. . . It would shut off without warning, sometime it would restart immediately, sometimes not!!!. . . Extremely dangerous situations developed, which I was lucky!!! 1996 Jeep Grand Cherokee, 4. 0 , 6 cyl. . . . Spent 6 months doing repairs/ replacement parts and many ,many dollars spent tracking down part after part. Using diagnostics machine to determine faulty part. . . Problem was the power control module ( pcm or ecu same part) was defective and either was misreading codes or giving out bad codes to parts (like to the crank shaft position sensor or the coil, or the 01 or 02 ox sensors or it goes on and on and on). Not sure how it works but you get my drift. Since signing up with cnet. Com, have found many people across America with the same issue on Jeep with different years (1994/2000) and models. To search. . . Look up Jeep stalls or Jeep fixed and you will see other topics and forums around that topic and you will also see where the manufacture doesn't know how to address the problem either. Another possible recall issue is the screws that hold the pcm might be too long and are grounding out the unit after paint wears off on firewall. . . Important to read all articles and different forums!!! . . . Is a must lastly. . . Instead of replacing pcm's, is it possible to have the pcm re flashed under recall??? I'm stretching, but maybe electrical power storms and rain is causing parts to defect??? lastly. . . Jeep parts consists of module power units that work or don't work but the pcm reads the codes and adjusts the workable of the motor. . . Another issue is that there are several issues that will shut down the motor besides the fore mentioned parts. . . Ie. . . Asd relay, the security system, door locks, steering column, the electronic key, the back windshield wiper. . .
