Automatic Transmission Control Module problems of the 2015 Jeep Cherokee - part 2

Purchased 2015 Cherokee in January, 2015. First recall in Feb 2015. Software update for transmission and rapid response transmittal. Shifting problems started shortly after update. Hesitation from a stop; delayed start and then "takes off"; surging forward without foot on gas; shifts up when coming to a stop with foot on brake; clunking noise started at 7000 miles. Took it in for recalls on airbag and radio security and told dealer about transmission issues. Was originally told they would have Jeep for 2 hours. 7 hours later they called to tell me they did several software updates (ptu, rdm, dtcm, pcm, bcm); when I went to pick it up I asked for details on each update. Frustrated when I was told it would "take some time for the car to learn my driving habits. " I asked, "what happens when I am teaching my kids how to drive (twins that will be driving in a month)?" the service tech told me that "the transmission would be really confused. " I expressed my concern for safety. Told him I never know when it is going to accelerate on its own or hesitate with a 5 second or longer delay. I asked how that could be safe when teaching kids how to drive. He didn't have an answer. Just said, "I understand your concern. " I have only driven it about 20 miles since the updates. Now it shifts quickly through the first 3 gears, still hesitates, and rough shifting. Keeping detailed records now. I've had my Jeep for 7 months (7000 miles) with 3 actual recalls, and 6 software updates that weren't recalls, just performed based on my complaints. The issues with this transmission are a safety hazard, especially when sitting at an intersection waiting to make a left hand turn and never knowing how the Jeep will respond. . . This isn't safe for an experienced driver. How can anyone safely put a new driver into a car that has these types of issues?.

It appears I've gotten the transmission bug that seems to be going around. One month old 2015 trailhawk v6 automatic with 738 miles on it. Started the car(2-7-2015) and notification came on dashboard that read, "service transmission," "4wd deactivated," "remote start deactivated,' "and put car into park then shift to desired gear. " I managed to get the Jeep rolling and drove directly to dealership. I talked to the service rep this morning(2-9-2015), and before he could say anything, I told him it was the tcm. He actually laughed because I knew every problem. I guess best case scenario is that the reset works. If not I'm sure there will be a tcm replacement. Worst case scenario is the transmission needs to be replaced, and at that point, they can keep it.

When driving the vehicle, dash lights would flash and check engine light would come on. Messages would state the there was a failure with the start/stop or 4x4 or transmission. Vehicle would not engage any gears, d (drive) indicate would be flashing, and I could only rev the engine. Vehicle would not advance and would not engage any gears. Had to shut off engine and turn it back on several times to get the transmission to engage. Check engine light is still on. Taken in for service four times now, update firmware, replace pcm, and now they are going to replace the wiring harness. Vehicle purchased on 12/31 and has been in for service with major failures with the transmission since 1/13/2015.

Vehicle had driveability issues with transmission slipping in lower gears. Car has received three software updates to transmission control module prior to this incident.

Vehicle was traveling on interstate highway when service transmission light came on in the stored messages, then the malfunction indicator light and service engine light came on. Within minutes, driveability issues became apparent with no acceleration and slipping gears/unable to shift into gears. Once the car slowed/stopped, the vehicle was unable to shift into lower gears to move. The vehicle had received the p56 recall to update the computer software to the transmission control module one month prior to this incident.

Bought 2015 Jeep Cherokee brand new off the lot was so excited to own my first Jeep after 600 miles transmission failed and had to be completely replaced I was without it for 23 days. After I got it back and noticed the transmission either lunges forward when making a turn or looses power and reves up then engages took it back and dealer says we are aware of problem but there is not a update or fix for that. . . . I have never felt more unsafe or unsure about driving or trusting a vehicle than I do now. I have been back to dealer to have many updates/recalls done and tcm had to be replaced not just updated. . . I wish I never purchased a Jeep . O yeah I almost forgot the washer fluid liquid housing container is leaking took it to the dealer they said it has a crack in it defective so they need to order a new one. . . . . . Ugghh what next?.

After a simple first required service of an oil change, the engine light came on. We learned that this engine light coming on was the result of the dealership service department performing a recall campaign service to reprogram the transmission and powertrain control modules. The campaign to reprogram the transmission control modules was completed, without our knowledge, during the time the vehicle was in for the oil change. The vehicle was brought back to the dealership twice more in two days to "figure out" why the engine light was coming on. The dealer is now replacing the entire transmission.
