Filed Apr 7, 2025 · Electrical, Engine · IL

Vehicle Identification Number (VIN): [XXX] Vehicle Mileage: 29,200 miles Involved Honda Dealership: McGrath Honda, St. Charles, IL Details of Your Inquiry: I am seeking assistance regarding an ongoing issue with my 2023 Honda Accord Sport Hybrid. The first time I noticed this issue was in the summer of 2024, when I experienced a similar set of alerts while driving in a parking lot. At the time, I didn't think much of it, as the vehicle seemed to return to normal shortly afterward. However, on [XXX], the problem occurred again, but this time it was more serious. While driving in a subdivision in Bolingbrook, IL, at approximately 25-30 MPH around 8:10 PM, my vehicle malfunctioned and displayed numerous system alerts, including: Adaptive cruise control system problem, Collision mitigation braking system problem, Road departure mitigation system problem, Electric power steering system problem, Electric parking brake system problem, Tire pressure monitor system problem, Brake system problem, Brake hold system problem. Additionally, my Honda app sent a warning stating, “Brake system problem, drive with caution.” During this time, the vehicle experienced a significant loss of power, with no braking or acceleration available. I was unable to use the brake pedal or accelerate, which caused immediate safety concerns. Luckily, I was in a subdivision and not on a busier road like Weber Rd. or I-55, as this could have resulted in a dangerous accident. I was able to coast the vehicle to a stop at the side of the road, where I waited for a few minutes. I then cycled the vehicle off, waited a few more minutes, and turned it back on. The vehicle started, and I was able to drive back home. A video was recorded showing the alerts on the dashboard. I brought my vehicle to McGrath Honda for diagnostics on March 28, 2025. The dealership found multiple lost communication codes from various subsystems, but they were unable to replicate the issue.

When overtaking Semi-trucks on the passenger side, as I approach the truck's cab, my vehicle turns off cruise control and sometimes applies the brakes while the vehicle icon will show an obstetrical is in my lane. On a few occasions, the emergency brake bar flashes and the car decelerates. Once I react (usually by applying the gas) the warnings go away. When I called Honda, they said to go to the dealer. The dealer states the vehicle is within specs and there is nothing they can do.

This happened on [XXX] at roughly [XXX] pm. I bought the new 2023 hybrid accord ex-l in June 2023 and the car only had 12413 miles. I was driving in Slidell, LA along [XXX] road towards [XXX]. I was driving 45 mph with adaptive cruise control. Suddenly there were lots of warning lights on. I don't really remember clearly how many warning lights since I was shocked. But I think that the "check engine", "tire pressure", "road departure", "traction", and "brake" were on. It was like fire work and at the same time, the car was losing power and the power steering was becoming stiff. Luckily there were no cars behind me and I was right by the entrance of a subdivision. I was able to turn into the entrance of the subdivision and the car basically stopped by the stop sign, kind of like dead. I was blocking the road and had to restart to car. But luckily I was able to restart and then there was only one warning messages left, the brake (please see photo). It says " Brake system problem, Brake performance may be reduced. See your dealer". It was after 7 pm and I didn't think the repair department was open. So I took a photo and slowly drove to Abita Spring. After parked my car for maybe two hours and I then restarted the car, everything seems ok. No warning lights at all. So I drove back home. Was busy on [XXX] and [XXX] (Wednesday and Thursday), finally went to the dealer on Friday, [XXX]. There was no codes and the dealer cannot do anything even after showing the photo. Was told to pull over to the dealer and they need the code. It's been two weeks and the car seems fine. But if someone drives on highway, ~70 mph, this can be fatal. And HONDA needs to address this!

Power Steering Failure. It is available for inspection upon request. After taking a right turn, the steering got stuck and did not come back as expected. This caused car crashing into the curb on the road, severely damaging front right front rim and tire. The steering alignments after the crash has been impacted - steering has to be tilted to make the car go straight. There are multiple warnings signs that include Brake System Warning, Vehicle Stability Assist System Problem, Hill Start Assist Problem, Adaptive Cruise Control System Problem, Collision Mitigation Braking System Problem I have video of all the warnings that I see. The warnings disappeared for sometime and then came back. I am taking the car to a Honda dealership for inspection and repair tomorrow.

While traveling at approximately 72 mph along the NYS Thruway at approximately 6pm on Februay 17, 2024 the vehicle's emergency braking system activated. There were no vehicles or obstuctions present at the time. The cruise control system was engaged at the time of the incident. The vehicle slowed immediately to approximately 59 mph. The dashboard flashed a yellow light indicating to the driver to immediately brake. This happened very quickly and the vehicle then resumed normal speed. At the time of the incident the vehicle was approaching an underpass that was several hundred feet ahead of the vehicle at the time. There has been no incidents prior to this one. I believe our safety was put at risk, as the sudden slowing of the vehicle could have caused a rear end collision. At this time, the vehicle has not been inspected by the manufacturer, police, or insurance agencies.

The 2023 Honda Accord Sport Hybrid has 8302 miles and it had complete brake failure. We had just refueled the car and moving away from the pumps, the pedal sank to the floor. I pumped the brakes several times and was able to stop the car. This was at about 3MPH. Received a message on the dash that the brakes were compromised and not to drive the car. Shut the car off and restarted. The brake pedal was spongy. We drove home (about 2 miles) very slowly, using the brakes minimally. When I got home, I shut the car off. I decided I wanted a picture of the dash warning, but it didn't return. Went for a very low speed drive to try to duplicate the problem, but it seems normal now. Bringing to original dealer, 12-17-2023. We've had several other issues related to the parking brakes and cruise control on 11-13-23. Brought to dealer on 11-16-23 and they were unable to fix due to part shortage. They failures displayed are: 1 - BRAKE SYSTEM - parking brake not available. 2 - BRAKE SYSTEM - Brake hold system problem. 3 - adaptive cruise control system problem. The drivers side rear seatbelt will not retract. Brought to dealer waiting for part to repair. We are fortunate this happened in a parking lot with little traffic. If this happened on a roadway at speed I would have no way to slow the car. This is a Hybrid so I am not able to downshift, the parking brake is not functioning due to previous problem and the electronic drive doe not provide compression braking if I shut the car off. I would be happy to answer any further questions you may have.

I experienced 8 separate malfunctions in the CMBS in 2 days. The systems problems still persists. And it is obvious that Honda is aware of the problem since nothing has changed in 10 years according to reports of the first incidences of the CMBS failures. I drove on the NAFTA super highway which is congested with semi-trucks. As described in the owners manual pg 413 it is obvious there is 1)radio waves interruptions, the car shutters just as the rear of the cab is approached, mostly like the transponders location, 3 occurances this trip but many more in the past 6 months since I purchased the vehicle. 2)Reflection from a trailer pallet bundle wrapped in clear plastic, it was obvious the glare from headlights created a reflection and caused the system to shutter the brakes and flash the BRAKE sign. 3) while driving into a curve with yellow reflective arrows caused the brakes to shutter. 4)in a dangerous construction zone while driving in the right lane against large white concrete barrier, the reflection created a sudden brake shutter. 5)Today, while driving in the rain through a neighborhood street, testing the cruise control at 27mph the brakes shuttered at a puddle reflection. I just got home from the Dealership who has no answers or solutions. And is very aware of the problem. Which in itself sounds unscrupulous. Paying all this money for a safety problem that could easily cause an accident.

When driving the car at 45 mph, warning lights came on for: (1)Vehicle Stability system problem. Reduced traction and handling. See your dealer. (2)Electric power steering system problem. Steering assist reduced. See your dealer. (3)Hill start assist problem. Vehicle my role upon brake release. See your dealer. (4)Adaptive cruise control system problem. See your dealer. (5)Brake System problem. Brake Performance may be reduced. See your dealer. While these messages flashed, the car lost ability to accelerate, steer very well, and brake very well. The car came to a stop after it slowed and I slammed on the brakes as hard as I could. I placed in in park, turned it off, and then turned it back on. It drove normally for a few minutes and then another warning light came on for a few seconds. It disappeared and the car drove normally. The dealer said a code showed up but they couldn't replicate the issue. They ended up replacing the battery because they didn't want to give it back to me without a fix. About 4 weeks later, we were stopped on the highway and in park waiting for over an hour. As we sat there, the warning light came on that said, "Electric parking brake system problem. Parking brake not available. See your dealer." The dealer kept the car for 2 weeks, couldn't replicate the problem, and said there were no codes. They offered no fix. 2 weeks after that, the car flashed up a warning light while driving 5 mph in a parking lot. The warning light said that the "Lane assist" was not operational and that I should contact the dealer. I couldn't take a pic of it because it only flashed up for 5-10 seconds. I'm taking the car in later today.

While driving I received a message stating the automatic emergency braking, steering assist, lane keeping assist, braking assist, hill hold, adaptive cruise control all we turned off. Additionally regenerative braking was also turned off. This system problem did not clear after the car turned off and back on. The dealership addressed the issue, but unsure of the cause. All codes were cleared and the system was recalibrated. This is the first incident of this type with this vehicle.
