Automatic Transmission Control Module problems of the 2019 Jeep Cherokee

The contact owns a 2019 Jeep Cherokee. The contact stated that while driving at an undisclosed speed, there was a clunking sound coming from the vehicle while attempting to shift gears. There was no warning light illuminated. While driving at an undisclosed speed, the vehicle unexpectedly hesitated while attempting to accelerate. There was no warning light illuminated. The vehicle was taken to a dealer where it was diagnosed and determined that the pcm, tcm, and dtcm software had failed and needed to be reprogrammed. The vehicle was not repaired. The vehicle was taken to another dealer, where it was diagnosed with ptu failure. The contact was informed that the ptu needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA hotline for assistance. The approximate failure mileage was 82,000.

Pcm was replaced and a code came up that the ptu failed. Ptu part is on national backorder. Would like this VIN# put on recall so Jeep will cover rental car expenses.

Pcm fails intermittently. Dealership is replacing it and has the defective one. Safety is definitely an issue because the vehicle stalls without adequate time to pull off of the road. Unable to move it off the road because it does not engage the transmission. Dealer has been able to replicate and confirmed the problem. Component has not been inspected by anyone other than the mechanic at the dealership. Several warning lights go off just as the problem occurs but not in time to get out of unsafe situations. Recall #18v524000 on 8/8/2018 covers the problem I am experiencing but my vehicle is not in the VIN series covered by the recall. I strongly believe the series my car belongs to should be included. This is a safety issue.

The contact owns a 2019 Jeep Cherokee. The contact stated while driving approximately 50 mph, the transmission erroneously shifted from 4wd to 2wd, and the vehicle would no longer accelerate while depressing the accelerator pedal. After pulling off the roadway and restarting the vehicle, the vehicle remained in 2wd with the check engine warning light illuminated. The contact stated that later while driving at an undisclosed speed, the transmission control module (tcm) message displayed. On another occasion while driving approximately 25 mph, the transmission message displayed, and the transmission erroneously shifted to reverse, and the vehicle would only operate in reverse. The vehicle was towed to the local mechanic who was unable to determine the cause of the failure. The manufacturer and local dealer were notified of the failure. The failure mileage was 36,000.

Urgent: date of near life & death situation. 10-6-2023. This 2019 kl Cherokee lost accelerating power while in heavy traffic. As the car was losing speed the "d" drive indicator on center dash started flashing a moments later 2 messages displayed: msg 1: service transmission restart in park with vehicle @ zero speed. Msg 2: shift to park or neutral press brakes and select gear. (center dash is the screen between tachometer and speedometer) followed instructions, turned key to off position for a few seconds then started engine placed shifter in drive, accelerated engine to 2000 rpms, car failed to move. Turned key off a second time, waited about 18 seconds for the mileage readout to clear then another 6 seconds (+-) for the outline light bars for the center screen to clear. Then when started it engaged a drive gear. Even in residential areas there are large trash trucks and large delivery trucks hurrying about, added to this vehicle faulting in roadway much less a center lane on the interstate with no time to pull out of traffic. Don't trust the car seat and booster seat even with air bags to save your children. Action is required to remove these vehicles from service after it has been proven the manufacturer cannot supply the dealership with a successful repair for a well documented failure of a common safety hazard in many of their vehicles. The dealership did not duplicate the problem but did confirm all of the information supplied them matched with the faults stored in pcm memory. Not being able to duplicate leaves the technician with just an image of the perils these faults puts the operator and public in, catastrophic. No specific component could be proven at fault, with vehicle operating normal. After a diagnostic fault code retrieval the option was to allow them to spend maximum 6 hours in electrical testing to verify integrity of electrical connections and components. Trust and confidence in an organizations leadership to accept responsibility for mistakes.

I believe my pcm went bad.

While driving at 55mph. The vehicle shutoff and would not restart. Very dangerous to lose power at that speed. Engine light came on and stayed on. Vehicle would not restart. Engine codes read high voltage on pcm modules, brake modules, automatic transmission modules.

While driving my Jeep suddenly shut off. This happened twice, so I took it to liberty Jeep in libertyville. I was told that they would need to do a pcm reprogram and that it will now burn 1 quart of oil per every 1000 miles and that I would need to keep an eye on it to continue to top of the oil so the Jeep doesn't shut down. This is not acceptable for a dealership to say. I am fearful of driving long distance on highways with this now and would like to get out of this lease. I have attempted to discuss with the dealership and I haven't had any luck. Owner or managers do not return any emails or phone call. This is very disturbing.
