Ecm computer , o2 heater sensor from ecm and controls transmission shift points . Replaced o2 sensors and transmission is controlled by ecm not shifting correctly will stay in first gear and hard shift to second can create loss of control in wet weather conditions.

The dashboard will display odd behavior and all of a sudden the ignition will cut. Total loss of power. This has happened in the past with children in the vehicle. Very dangerous. Resetting the key will reset but it is random.

The vehicle was in motion and pulling from my driveway onto a city street when this happened. Both drivers and passenger center sections of the frame rusted from the inside out with no visible indication on the outside of the frame rails. Water and debris enter through holes used in the manufacturing process and due to no drain holes in any of the lower points the water and debris rot the frame away. In my case the transmission pan on the drivers side of the vehicle fell free when the bottom of the frame rail on that side crumbled while entering a city road from a private drive at less than 5 MPH. Damage was done to the transmission, transfer case, one axle, and the rear drive shaft. The vehicle was towed to a private garage but they were unable to place it on a lift to inspect the damage as the frame would have crumbled and snapped in additional places thus creating a hazard and possibly deadly situation the technician inspecting the damage. The vehicle was then placed on a flatbed and brought back to my home.

Takata recall, oil pump drive gear, PCM powerterrain control module I believe needs to be reprogrammed I have a failure of power while driving down the road like its getting to much or to little fuel and last week my oil pressure will not budge my gauges are slowly going out on my dash and the airbag light on dash blinks rapidly with the check gauges because of my old pressure I have taken it to multiple places to get it diagnosed and they say it is the oil pump drive gear and the PCM needing to be reprogrammed along with that being out of line my ground connections seem to be bad but I replace all of them from the battery to the engine block the dash and a couple more it has pressure but doesn't sound like it. All of this started happening at about 143,000 miles I have replaced multiple parts including the oil pump oil sensor all of the ground wires and terminals and checked as many relays as I can. Along with my dash when I had got it it had 130,000 miles on and the airbag light has always blinked and noticed a loss in power when I drive since I've had it, it runs through spark plugs and coils packs monthly and has since I've gotten it I drove it to georgia and back and it sounded like it was getting worse and just kept getting worse and worse until last week my oil pressure gauge says I have no pressure and the engine has oil pressure but you can tell it's going more and more out of line. I know when I look up my VIN number it says it's been updated since march 14, 2019 but when I log into another app it says I have recalls I don't know what to do or how to fix it but it definitely is the three recalls that was put on the 2005 jeep wrangler tj.

I get a code that pops up after being on the highway for a time that says something regarding transmission. Also the transmission is slow to shift between drive and reverse sometimes and grinds (auto trans). There have been multiple reports of PCM issues that require rebuild or replacement but availability is scarce. Could be poor design.

My wrangler has sever rust damage on the frame, windshield frame, passenger rocker, and firewall. The frame has rotted from the inside out and caused the transfer case mounting bolts to pull through. The vehicle was in motion when this happened but luckily I was pulling out of my driveway and not on the highway headed to work. The windshield frame rust caused holes that allowed water to leak inside the vehicle causing the floor to rust from the inside out as well. These issues continue to happen again and again with each new revision to this model. When and what will it take for the company to be held accountable to their negligence?

Jeep started stalling either when parked or in traffic. Dealership says its the powertrain control unit (PCM or computer). Twice engine stalled as I was driving. Once as I was making a turn luckily had enough momentum to pull over and another time getting ready to proceed after a red light it stalled all of a sudden and again able to pull over. I have found many jeep owners with this same problem and I am aware jeep is aware but nothing has ever been done. Started mothers day 2018 and a few times up till july when I just parked it and had it towed to 3 shops including dealership.

Over a period of several days the vehicle started shifting hard and eventually went into "limp" mode and started throwing different codes for various sensors. After many visits to different mechanics I researched the problem myself and pinpointed the PCM as the problem.

2005-2006 jeep wranglers are incurring an apparent large number of PCM/ecu failures (as evidenced in many online forums and a high backlog of PCM orders which jeep/chrysler is unable to fill or provide an eta for). The failure of the PCM reveals itself in many ways including emissions system failures (and resultant vehicle inspection failures I will add), transmissions failing to shift, hard forceful transmission shifts with vehicle lunges and more. On my vehicle specifically the o2 sensor codes are coming on and the vehicle will randomly not shift out of second gear which presents itself as a safety hazard when entering high speed freeways and interstates. The o2 sensors were replaced new with oem parts and the codes did not go away. The fault was traced by a reputable mechanic (christian brothers automotive) to the PCM and further online investigation indicates this a frequent and recurring issue. When I attempted to replace the PCM through jeep/chrysler I am unable to because the part is backlogged. I have placed a pricey $1600 order for the part but thus far (1 week) I have not been provided with an eta or any answers as to why this design defect has not been addressed. Based on the large number and type of issues reported online with this PCM I am left wondering why it is not a safety, emissions and/or recall issue. My specific PCM pn is r6044529ac but multiple variations of the pn appear to be effected.
