2024 Honda Accord Electrical Problems

Apparently a very well known issue, I've had my car for 17 months and the software error see dealer had been on every time I start my car for the past 14 of them. And sometimes when I'm driving. Took it to the dealer, as the screen prompts, they said they reset it, turned it on, and there it was. Don't think they even did anything, except maybe waste my hour and a half and then try to sell me services. I know there is a known issue with the software on this model shutting down the vehicle whilst driving, I sure hope that isn't the case with mine. I'll try to take it back to the dealership, but like I said, they either didn't know, couldn't fix it, or just wanted me to get new brakes the first time I was there, and I'd really rather make sure that it gets done correctly if I bring it back. Thank you very much, and have a great rest of your day

Honda put out a software update in March and found out Midway through that there was an issue with it so they stopped it on their end. My car unfortunately is experiencing an issue which the nhtsa apparently 23- 036, 044 and 045 I do not have systems updates menu I don't have a connection menu my car cannot receive a Wi-Fi signal or a Bluetooth signal it can only transmit a Bluetooth signal and Wi-Fi signal at this point. The car's been to Heritage Honda in Parkville Maryland twice I tried to take it back to the dealership where I bought it from actually, where it's leased from and still under warranty of course. Honda of Parkville said they did 23-044 and where it did clear the air that I was getting on my dash where it said systems update unavailable see dealer, I still do not have the connections menu and I don't have systems update menu the main apps menu on my display unit is missing the settings gear. The power/volume button of the display is supposed to do a soft reset if you hold the power button in for 10 seconds all attempts at the back door resets whether it be the display unit power button, doing the steering wheel buttons, pulling the TCU fuse and the audio backup fuse and I've even gone so far as to disconnect the battery for well over an hour all of this is ineffective at bringing those menus back. I even have access to an Autel Maxisys Ultra scan tool which can go in and reset the OTA module it can also perform Hondas updates via the j2534 pass through on its VCI adapter again all of this has been unsuccessful except for the attempt to do a software update using Hondas rental ihds software that they will allow you to purchase a pass for a day. I haven't tried that The dealers just don't seem to think there's a problem with this car I've got the owner's manual showing this car is capable of being a transmitter and a receiver for Wi-Fi and Bluetooth. They're telling me no that because it's an ex with the 7-in monitor that particular trim level does not

In December 2024, I was driving my 2024 Honda Accord Hybrid Sport on a clear, dry day after school when the car just completely lost power out of nowhere. The dashboard went crazy, flashing a bunch of different error messages every few seconds. Because the car wouldn't respond, I ended up in a side-impact crash. I was able to turn on/off the car after putting on my hazards and I was able to drive it normally and drove it towards the side of the ramp. I called my dad and after some time and turning the car on and off, the error messages disappeared and I was able to drive it safely back home. I tried to file an insurance claim (State Farm #51-78K9-28M) back then, but they blamed my driving because the Recall TN2 (Campaign 25V785) hadn't been announced yet. I ended up giving up on the claim because money was tight and my dad was worried about insurance costs, but the car is still dented and scraped from that day as the error messages disappeared after I turned on/off the car on the side of the highway. I just want it on the record that this 'loss of drive power' recall caused my accident a year ago after seeing the recall on the mail.

Vehicle was taken to Honda of Round Rock for the Integrated Control Module (ICM) Recall (NHTSA Recall 25V785). The dealership performed partial service but stated a 'gateway' part is on backorder. Since this service, the vehicle has been returned to us with a non-functional speedometer, non-functional speed sensor, no A/C/defrost, and multiple disabled safety sensors. Driving without a speedometer is a severe safety hazard. The manufacturer has provided no timeline for the part and refused a loaner, leaving us with an un-roadworthy vehicle as a direct result of a recall repair attempt.

Yesterday, January 30, 2026 as I was driving (approximately 30mph) my car seized, came to a stop, dashboard lit up with multitude of words/symbols. After approximately 15 seconds I was able to use the gas pedal and the car drove. My safety was at risk, this sudden stop jolted me hard. If there was another vehicle behind me I would have been hit. The warning messages were so quick and cleared away with seconds that I cannot recall. I drove to my local dealer and the battery cables were checked and ok. I scheduled an appt for Monday Feb. 2nd as this was Friday. On January 21st this local dealer replaced my battery, after months of "computer glitches" that were never resolved with two dealers and 4 dead batteries.

The contact owns a 2024 Honda Accord. The contact stated that on several occasions while driving at undisclosed speeds, the vehicle unexpectedly came to a stop without the brake pedal being depressed. The “BRAKE” message was displayed on the instrument panel. The failure occasionally occurred while the cruise control feature was activated. The contact received notification of NHTSA Campaign Number: 25V785000 (Electrical System). Additionally, occasionally the electrical system was inoperable, and the instrument panel failed to function properly, and the trunk and fuel door unexpectedly opened. The contact also stated that the automatic door locks failed to function properly, requiring several attempts to enter the vehicle. The vehicle was taken to several dealers; however, the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failures, and the contact was offered a buyback option for the vehicle. The contact expressed concerns that, due to the multiple failures, the vehicle was unsafe to operate and created a hazardous condition, because the vehicle was almost in a crash with children inside the vehicle. The approximate failure mileage was 33,000.

The vehicle's infotainment system displays error code TT04 on every startup, preventing over-the-air software updates, including any potential safety-related updates delivered through this system. The TT04 telematics error appeared immediately following dealer service department completion of fuel pump recall service (NHTSA campaign 24V-763) on 4/12/2025. The vehicle exhibited no infotainment or telematics issues prior to this recall service. This suggests the recall repair procedure either was performed incorrectly or has an inherent flaw that damages the Telematics Control Unit (TCU) communication system. When I returned for subsequent recall service (NHTSA campaign 25V-785), the dealer dismissed the issue as 'normal' and refused repair, only offering to address it after I filed a formal complaint with management. This pattern suggests dealers are aware this is a consequence of recall work but are systematically dismissing customers rather than correcting their errors.

The Instrument Panel Display combined with the Front Sensor Camera failed. This risked my live as well as others lives on the road due to the ill ability to predict when it will fail as well as the difficulty to control the sporadic behavior. The Lane Keep assist system would also overcorrect and have very strong and hard to control corrections with the wheel. The Instrument panel would also turn off mid drive and I would not be able to see my speedometer. It has been seen by multiple diffferent Honda Service Centers and no one can figure out the issue. Camera issues have been recalled on previous models.

Bought a brand new Honda 2024 at a dealership, since picking up the car we noticed it was black and white and not clear, assumed it was a setting issue so paperwork was completed and we took the car home. It was a safety issue as having it black and white and reversing it was hard to see and several close calls on collition when backing up due to camera malfunction. Issue persisted, notified dealership and appointment was made to replace camera. Issue was confirmed by dealership and camera replaced. About to exit the dealership, put car on reverse and issue persisted.
