2024 Honda Accord Driver assistance Problems

Subject of Complaint: Sudden, simultaneous failure of critical safety and driver assist systems originating from an electronic sensor/control module failure inside the electronic power steering (EPS) gearbox. Description of Safety Hazard and Dashboard Indicators: While operating the vehicle, the Driver Information Interface (DII) suddenly illuminated with multiple critical safety faults simultaneously. The primary indicator was the amber Electric Power Steering (EPS) System Problem warning light (steering wheel icon with an exclamation point). Due to the electronic architecture of the vehicle, the loss of reliable data from the steering gearbox caused a cascading failure across the Honda Sensing safety suite. The dashboard displayed a sequence of distinct system errors, explicitly disabling: Lane Keeping Assist System (LKAS) Problem Road Departure Mitigation System Problem Adaptive Cruise Control (ACC) Problem Safety Risk to Occupants: The unexpected failure of the EPS system immediately compromised the vehicle's handling characteristics, significantly increasing the steering effort required to control the vehicle. Furthermore, the simultaneous and total disabling of the Lane Keeping Assist, Road Departure Mitigation, and Adaptive Cruise Control systems unexpectedly stripped away active crash-avoidance features. This sudden degradation of vehicle control and driver-assist capabilities creates an immediate, severe collision hazard on public roadways.

"A manufacturer Over-the-Air (OTA) firmware deployment has caused a root-level cryptographic security certificate mismatch between the Audio Unit and the central CAN Gateway, matching Honda Tech Line Article A29051. This network failure has forced the vehicle's VSP (Vehicle Sound Device for Pedestrians) Safety Module into a permanent hard offline (NG) state, operating the vehicle out of compliance with FMVSS No. 141. The manufacturer (American Honda Case #[Your Case Number]) and authorized dealership (Heritage Honda Parkville) have been provided video proof but have actively refused to schedule the vehicle for a high-priority warranty repair or issue a safe alternative loaner vehicle, leaving a safety defect active on public roads."

Brand new 2024 Honda Accord touring purchased on Oct.3, 2023. Started having issues with the braking system around June 18, 2024. I contacted Sons Honda where the car was purchased. Sons told me to contact American Honda. I contacted American Honda and we were in a back and forth conversation for 18 months. until they offered me $3000, which was not enough to start to fix the several other issues with the brand new car (lemon). Luckily, no accidents have happened yet. I would like to mediate with American Honda, NTSB, and myself for at least $6,000 , so I can start to have the vehicle repaired. Along with the other minor issues I have with the brand new car (lemon). The vehicle has a host of recalls that makes the car more unsafe to operate.

I was going on the highway at around 65-70 mph and the road was clear. The Honda Automatic Emergency Braking (AEB/Collision Mitigation Braking System) activated and I couldn’t do anything, the brake was sudden and my speed decreased to almost 30mph. There were no cars behind me or it would have definitely been a fatal rear-end crash. The road was clear, there were no cars/object ahead of me on the road.

I was traveling to Kentucky from NYC in December 2025 and while in Pennsylvania a sign on my dash stated your safety equipment was out because of a build up on the front lens outside of the car and it stated to stop and clean it off, so I pulled off to the side of the highway and stopped my car and when I stiffed it into park there was a griming noise from the transmission. When I went into the dealership for my next oil change I reported it and they didn't even want to note this down on my service report. They said it happened to long ago and they didn't care about the problem, I just wanted them to know for future use. Also another issue happened a couple of months prior while stopped on the highway near my home because of traffic, my car shifted from drive into park by itself without the shifter moving I don't know what happened but I moved the shifter from drive to park and moved it back to drive. And again I reported this and they didn't want to even note on my service report . Not happy about this situation either. Then I received a text message from the dealership that they wanted to buy my car against a trade in and I said to myself if they refuse to record my problems I 'll take my business somewhere else.

In Feb. 2026, I had a software recall service performed on my Honda Accord. Later that same day, a persistent error message appeared on my dash: Software Update Not Available See Dealer. I contacted the dealer and they said sometimes that error message clears on its own and to wait and see. A few days later as I was leaving work, I turned my car on, put it in reverse and realized I had no propulsion or power steering. I put the car back in park and restarted it and drove it straight to the dealer where it sat for about three weeks as they tried to clear the error message. They were not able to reproduce the issue I reported with my car being on but without power. I picked up the car on 3/16/26. After leaving the dealership, it began sputtering and lurching. I could see on the powertrain display that the car was not communicating well between the engine and hybrid battery. I pulled into a parking lot and put the car in park and it began functioning normally. I called the dealer and they said to bring it back if that happened again. It has not. Tonight, I was pulling up to a red light when my car suddenly slammed on the brakes and displayed Lane Departure Mitigation Off. I attempted to restore that safety feature and realized my car had lost power. It did restore power and I was able to drive home, but I am terrified of my car since it engaged the braking system for no reason and disabled a safety feature plus losing power. During my car's time in the service department, it got a new CAN gateway module and telematics unit along with repeated attempts to make the software update glitch free to eliminate the persistent warning messages that had been displaying. Honda tech support was involved, and I have contacted Honda corporate with my concerns about the safety of my car but am waiting for a response. My perspective is the software recall update ruined my perfectly good car and I am worried I am going to lose power and get injured or worse.

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.

I've had 3 phantom breaking experiences. Most recently while driving on a straight wet road (one of the other experiences the road was also wet). I was travelling at approximately 30-33 mph and the system did an automatic hard break with a perfectly clear road ahead, no cars, people or animals in front of me or on either side. Thankfully, no one was behind me either. The other wet road auto break instance was when I was traveling between 22-26 mph on a road with a slight curve and vehicles were parked on the right side of the road. I was turning appropriately to take the slight turn and suddenly the breaks slammed on. There was no danger of me hitting anything. The third instance was when a vehicle was crossing a two lane road from left to right ahead of me. Two vehicles were ahead of me in the right lane traveling the same direction I was. My vehicle slammed on the brakes assessing that we would hit the vehicle crossing the lanes. There was absolutely no danger of that happening, I was multiple car lengths back. Should this happen when vehicles are traveling behind me, it could cause a very bad accident and it would appear that I would be liable for slamming on my breaks. I will begin trying to disable this safety feature whenever the roads are wet and make an appointment to have the dealer inspect the car. This has not been inspected or confirmed by anyone at this point. When this occurs, there is no warning - just slams the breaks and a "BREAK" warning with alert tones appears in the dash. No other warning lights or malfunction lights are on in my dash display. The vehicle is available for inspection with advanced notice so that I can make arrangements.

Car parked for 6 days while on vacation. Came back it started fine but 30 mins into travel, I lost power steering while on the highway next to a tractor trailer and the warning lights were shifting through a cycle of warnings of things not working. It told me to go to the dealership which I brought on my way home. They looked and said it was because i didn't drive it. The car is 1 year old and that battery should be working. I travel at least 120 miles a day5 days a week so there isn't a deficit of charging. Regardless, this should not be normalized by Honda. There should be something I can do to check this situation prior to driving. I do have a video of the cycle of warnings but I can't upload it here. Contact me for it if you would like it.

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.

While engaging Adaptive Cruise Control on highway speed, all the sudden I lost the sight of the car in front of me on the display, almost causing a collision, I also lost the correct Waze display. After I stopped the car, shut off engine, then restart the car, re-engaging Adaptive Cruise Control, both problems disappeared. This is an intermittent problem, it should be asap investigated then recalled due to huge safety concern !

On October 3, 2025, at approximately 1:00-1:30 PM, I was driving southbound on the Hardy Toll Road in the far-left lane on my way to a friend's house. Road conditions were dry, and it was a bright, sunny day. While driving, I noticed something felt unusual with my vehicle. Other vehicles began passing me, so I checked my side-view mirror to see if there was an issue with my rear wheel, but I did not observe anything. When I looked forward again, there were no vehicles directly in front of me. Suddenly, my car locked up, and the word "BRAKE" appeared on the dashboard. My vehicle immediately began veering sharply to the right. While veering, my vehicle was struck on the passenger side (T-boned) by another vehicle. The impact caused me to collide with the guard rail, strike a freeway sign, and ultimately crash into the tree line near the water off the roadway.

When making a left turn, my car suddenly bucked up onto the air feeling like I ran over a big obstacle which was not the case. Car came to sudden stop and I was thrown forward over steering wheel. Thankfully no one was behind me or it would have been catastrophic. The first week I owned the car, when going through a car wash, the car started jumping up and down and wouldn't move forward. Had to back out of carwash. Dealer told me it was the collision mitigation system and to turn it off before going in. The "brake" light on dash periodically flashes when no cars are in front of me. I am truly afraid to drive this car which only has 5,800 miles on it. Dealer can't find a problem. I am turning off collision feature every time I drive, but what if I forget? I believe this is an extremely dangerous defect and should be looked into. It doesn't always happen, but when it does...

I purchased my Honda accord June 21, 2024. For the first 3 months, the brake system indicator rectangle shape amber light (blinked on and off for several seconds) on 8 separate occasions when driving this car, so I brought the car to Honda Dealer that concluded it must be dust on the brake For the next 3 months, the brake system indicator rectangle light (blinked amber on and off) on 6 separate occasions, the Honda Dealer told me they could not find a problem with the brake, For the next 4 months,the brake system indicator rectangle light (blinked amber on and off) on 3 separate occasion , again the Honda dealer told me they could not find a problem but I noted that the dealer did not have record this on the work order. I then called Honda customer service (800-999-1009) support on June 23, 2025 at 1:17pm. I told the representative that the 2024 owners manual on page 84-85 did not have an amber brake indicator message among the 30 or so indicators in the manual. On page 493, the manual also mentions "If the brake system indicator (RED) comes on or blinks, there is a malfunction in the brake system" On page 494, the manual also mentions "if the brake system indicator (RED) comes on or blinks at the same time when the brake system indicator (AMBER), release the parking brake. The representative could not explain what a blinking amber brake system indicator meant and I should return car to the Honda dealer. Upon my insistence, my call was escalated and that a senior representative agreed that an blinking amber brake indicator explanation is not in the Owners Manual and could not provide me with an answer. Her best guess was that I was to close to a car in front of me (even though this has happened when there was not car in from of me). Can the NHTSA provide me with an explanation on why the brake system indicator rectangle light (blinked amber on and off) or have Honda provide the NHTSA with an explanation if this represents a dangerous situation to dri

Purchased new. Delivery date August 13, 2024 I've experienced an ongoing issue with the electronics since owning car. First issue was ECM failed. Currently having problems with the Lane Keeping Assist (LKAS). The car is alerting me that I'm not staying within my lane which isn't correct, the car then attempts to correct. The car attempts to correct, shows a lane departure warning but won't give any audible alerts as previous. During the time car alerts of road departure it clearly shows the car diagram within the road diagram. I have pictures taken showing such.

Several times the vehicle has automatically braked at low speeds (20-30 mph), nothing in front of the vehicle to cause this. Today it automatically braked...HARD...at 55 mph, again, nothing in front of vehicle, clear morning, road was clear. It braked so hard I'm pretty sure I have whiplash. I immediately called Victory Honda. They told me to go wash my car and call them back if it happens again. The only warning it gave was the brake light and beeping, but it was instant. Thankful there was no one behind me.
