Automatic Transmission Control Module Problems of Honda Accord - part 1

I am writing to let you know that 10/2/2024 my 2024 Honda Accord hybrid sport had sudden loss of drive-line power while I was traveling on the highway at 75mph. I was able to safely coast/navigate to the shoulder and stop. Steering and braking systems were normal. The car would not drive or restart once stopped. A tow truck was called to tow my car to the nearest Honda dealer to be fixed. There were no warning lights or sounds prior to this incident. Dealer determined root cause of problem was pcm not communicating with charging system. The pcm was replaced under warranty and my car was ready for pickup 10/18/2024.

Intermittently, the vehicle has a very violent shift at low speed (under 20 miles per hour). In the past, this had been mentioned to the dealer, numerous times, who claimed that the issue is not reproducible. However, during the visit on 12/06/2022, dealer mechanic(s) claimed that they did witness the issue and performed the following (per dealer's notes): "reset tcm and batter cable reset. " after which (the dealer notes state): "let the customer know that the trans will adapt to driving habits within 200 miles. If the customer drives hard, the transmission will learn hard to shift hard etc. . . " the second statement is nonsensical, since, most of the time the transmission shifts relatively fine, regardless of the driving pattern (I. E. Hard, mellow, etc. ) and the issue happens intermittently (every so many hundreds miles driven), at very low speeds with very little accelerator input, which indicates more of a software issue (and, possibly a mechanical design defect, coupled with the sw issue). .

This past week I experienced a catastrophic malfunction with the vehicle, while driving it appeared to short circuit and shut down. It would not allow me to drive in any gear whatsoever. Upon taking it to a mechanic at jiffy lube he stated the incident is identical and experienced the same issues that Honda and the dept of transportation deemed a recall that could have ended in severe injury or death. That issue and recall being (see below) powertrain:auto transmission control module (tcm,pcm). You see the mechanic at jiffy lube referred me to this recall due to his analysis and diagnosis being the same. Whom stated that the VIN doesn't state a recall, but it being the exact same model, make, engine, year, and coupled with the fact that it has tcm and pcm catastrophic damage, I was subjected to and encountered. I request this matter be further researched and investigation conducted because 1. 5 million vehicles were effected and I'd feel more confident and place more faith in Honda upon investigation.

My vehicle is a 2018 Honda Accord hybrid with 12,075 miles on the odometer. I was driving to work in the morning of 09/22/2021. The condition was dry and the outside temperature was around 60 degrees. I was merging onto the interstate in sport mode when all-of-the-sudden my car went into a limp mode. The check engine light began flashing and car lost 90% of its power. The engine made a knocking noise and began to shudder violently. I tried to switch it out of sport mode to get it back into eco but the message displayed on the dash said something like "unavailable at this time. " I was about a mile and a half away from work and was able to creep along the road to make it there as it was losing more and more power. When I got to work (with the engine still running) I lifted the hood and the engine was still shaking hard. I scheduled an appointment with the local dealership to have it looked at that afternoon at 2:00 pm. When I drove it to the dealership 3 miles away, the check engine light was no longer flashing and the engine seemed to run fine. When I called the service advisor later that afternoon to check the status of my car he told me, "the technician drove the car around with the scan tool plugged into it and it drove fine. He wasn't able to pull any codes from the pcm. " I find it to be odd. In my experience, whenever the cel illuminates, a malfunction code will be stored in the pcm until it is cleared. Why would Honda program the pcm to reset and hide the malfunction code so that we're not able to diagnose the issue? I did take the car into the dealership earlier this year to get a warranty battery replacement and to perform 2 recalls (one was an emission recall and the other was for the bcm).

My vehicle is experiencing the same issues as described in recall #11v395000, however my VIN is not listed as being affected by that recall. I contact Honda USA directly, opened a case #10120384, and was told that there was no extended warranty and nothing could be done. The vehicle is making a noise while driving and suddenly loses all power, this has only happened so far while the vehicle is in motion, exactly as described by the 2011 recall for the pcm, the check engine light in my vehicle also indicates the pcm is at fault, however because my VIN is not part of the recall any fix must be done out of pocket. The issues happening are exactly as described in the recall, because of this it seems as though additional vins might have needed to be included.

I have recently began to experience issues with my Honda where it suddenly stalls while moving. I have also noticed some clicking noises and surges as if the transmission is having issues. I see that there was a recall in 2011 for Honda to replace the tcm (transmission control module); however, my vehicle was not part of this recall and I believe I am now experience the very problems that the recall fix was to resolve. I am seeing the very complaint on your site from others who also have Honda Accords for the same year others. My vehicle has been regularly serviced and there have never been any indication of transmission issues.

Engine light and vsa warning light came on while driving on the freeway. Luckily my family reached our destination shortly after this occurred in fontana, CA. While the vehicle was in motion it would jerk and hesitate backwards while driving. I took it to rock Honda the following morning on 10/18/2013 in fontana, CA and they charged me 638. 60 stating the vehicle needed a pcm updated software and adjusted valves. In doing further research it seems I should have never been charged this as there is a recall id #74308 stating issues with the pcm and tcm and that Honda would update the control module software free of charge.

For the 2nd time since 2008, I've had to replace the sparkplugs due to pcm issues. The engine light will come on and gives an error code of p0303. Unfortunately you can only go to Honda to have the computer updated, and they will try to sell additional services. Today they refused to update my computer stating the only way to fix was to replace all the sparkplugs despite the service bulletin stating otherwise. Despite this being a manufacturer issue Honda has forced car owners to pay for this repair with no true fix existing.

I have a 2003 Accord 4 door ex with a v6 and automatic. I was driving along on the freeway at freeway speeds when suddenly the transmission seemed to have slipped out of gear and then re-engaged back into gear violently. Thankfully, traffic was light and I was able to limp off the freeway and onto a parking lot safely. After I came to a stop at the parking lot, I noticed the engine symbol along with the tcs and abs lights were illuminated. After the stop I had put the gear selector into neutral and found I had no forward or reverse in any selector positions afterward. Prior to the incident, the car was operating fine with no pre- indication of transmission problem. After a few minutes, I was able to get the car back into gear and proceeded slowly along city streets returning home. The transmission would shift erratically in and out of gear and then finally I was stuck in first gear with no up shifts. Dtc p0747 was stored. I replaced 9 quarts of atf-dw-1) and a filter (fk399) by myself. Honda shop service manual gave procedure for an oil strainer (Honda 25420-p7w-003), which is not accessible. A small filter element that can be replaced without disassembly of the transmission for access listed in the Honda illustrated parts breakdown as ( 25450-ray-003) and is available through Honda or an auto parts store such as o’reilly (fk399). I believe that the clean atf helped free up a sticking clutch pressure solenoid valve when the vehicle reached operating temperature and the pcm activates the solenoid.

I was driving my car home on Saturday evening. When I turned into my complex car in motion, it died. No warning. Everything shutdown. Engine, lights everything. I thank god I wasn't on a main road or freeway. I put the car in parked and it started back up with no problem. When I made it home, I researched my issue online searching for a recall. I found one that described my issue. However, the dealership and Honda advised me this morning that they are aware of the recall and my car was exhibiting the same symptoms. However, my car was not included in the recall because it was manufactured at a different factory. What!!! now in order for them to fix my car I have to pay $105 for Honda to run a diagnostic on it to tell me what¿s wrong with it. Really! why should I have to pay for that? I think that is unfair to my son¿s safety and me. You would think they would run a diagnostic free. I am soo afraid to drive my car. Anyone out there have any suggestions? I may just have to bite the bullet and pay the money. :( recall id # 11v395000 - power train:automatic transmission:control module (tcm, pcm).

Wife was driving at highway speed when car began to violently shake as if engine was misfiring. Check engine light came on, then severely reduced power. She was barely able to exit and make it across the access road and into a turn lane with the accelerator to the floor. Car still shook violently as she placed it in park. Dealership cannot explain shaking. Car only has 4,700 miles and was purchased new from servicing dealer. They said oil was 1. 5-2 quarts low so they topped it off. Tripped a code for a stuck soilenoid in the camshaft timing system so they reprogrammed the pcm and gave the car back to us. This was an extremely dangerous situation as my wife did not have enough power to move the vehicle out of traffic. Had there been more traffic in her way or someone following closely, she would have been in an accident. Dealer was still puzzled as to the power loss and shaking and just shrugged their shoulders. They said to watch the oil level and if this happens again to bring it back. We hope this does not happen again as it was dangerous and stranded my wife on the side of an interstate for 3 hours waiting on a tow truck. Please let us know if this warrants investigation or you need any additional information.
