2024 Honda Accord Hybrid: sudden loss of power

Filed Sep 28, 2025 · Electrical, Engine · CA

Wiring harness failed randomly at 42,000 with no damage to the harness, engine, or vehicle itself. Without the wiring harness the engine does not run properly and shakes violently, causing the car to lose power. This happened with no prior warnings, problems, or damage. Additionally the steering rack seems “loose” and changes direction quite quickly when hitting a pothole or uneven roads even at lower speeds. I have to make sure I constantly have a firm grip on the wheel so no sudden unexpected direction changes occur due to imperfections in the road.

I was driving at about 40 mph and the car lost all power and stopped in the middle of the road. Most all of the warning lights were on like low air pressure, reduced brakes and a brake problem light etc. Turned the car off and restarted and drove another 5 miles with the brake problem light still on. Stopped and restarted car and the brake light went off and all seems normal now. From my reading on Honda Accord Forums it might be a bad ICM unit? Will be contacting a Honda dealer soon.

On 11/11/2024 while at an intersection with a redlight, I was the first car in the "merge to the right" short lane, stopped and waiting on right lane traffic on the road that intersected to clear. When it was safe to go, I moved my foot to the accelerator and nothing happened. I realized my vehicle had lost power / "died;" that all dashboard lights were out. I quickly put my vehicle gear in "Park" position and restarted. It did restart but immediately a red warning light began flashing saying "Brake System Failure" and "Take Vehicle to Dealer." I was terrified as I proceeded in the right lane of traffic since I had vehicles behind me as well as in front of me and I had to cross an intersection with traffic merging from an interstate highway. There was not a safe place to go; all businesses along this stretch had no entry except on their back side. I had to proceed across several major intersections before I could get to a safe place. Meanwhile, warning lights continued and included more than Brake System Failure. One was showing a Warning diagram about changing lanes of traffic which I had to do. Obviously, brakes worked because I was able to stop when needed but I was afraid the brakes would not work which could have been deadly for myself and others. Once I was stopped and in a safe place, I called Honda Roadside Assistance and my car was towed to the nearest Honda dealership. As of this writing (six days from incident), Honda dealership is still investigating; they have not given me a cause or solution. They are providing me with a loaner car. There is no recall on 2024 Honda Hybrid Touring although there are multiple posts online with people saying they had same thing happen with this model vehicle.

I was driving on city roads when vehicle lost power going up a slight hill and I was forced to pull over to the side of the road. I received TDMS Failure first then multiple failures. Restarted and was able restart but received the following warnings: 1.Brake system failure, 2.Park brake failure, 3.Collision failure 4.Electric power steering failure, 5.TPMS failure, 6.Low speed braking failure, 7.road departure failure 8.Adaptive cruise control failure, 9.Hill start failure. Restarted again was able to drive the vehicle home but received the above warnings. Restarted again and received a brake system warning. After I got home, I restarted again and all the warnings cleared. This was a very serious error. If I was driving on the turnpike when power failed, my only recourse would be to try to pull over, if possible, stop the vehicle and restart. This would be a life-threatening situation. Checked tires front tires were 36# rear tires 33#. So, no tire issue to trigger the TDMS warning. The auto technician did some checks but did not see any codes. He also looked at the Honda forum for technicians and saw some of the same issues, but they didn’t provide a solution. I mentioned what I read in the Accord Forum about the Honda dealer this person went do couldn’t find codes but knew right away that it was the ICM ignition control module. The technician said someone drove it today and will drive it tomorrow. He will also call Honda Engineers in California for assistance. 6/11/2024 I was informed that the issue has been confirmed to be the ICM module, which is out of stock now. 6/27/24 I received a call from dealer service advisor that the rental was approved by Honda, but also the part was received and the car will be ready when I pick it up. Car was out of commission due to parts availability issues for 18 days.

While driving our 2024 Honda Accord Hybrid, the vehicle suddenly lost all power. Message on dash in big bold letters told me to BRAKE!!!!! even though there did not appear to be any reason to brake . When I tried to brake, I was not able to and the steering was difficult. I was able to pull over and finally stop. I was in a precarious spot and did not feel safe sitting in the car since I was just over the crest of a bridge endangering not only myself but potentially other drivers coming over the crest . Numerous messages on the dash related to steering and braking issues . Examples : Brake system problem Electric power steering problem Reduced traction and handling Brake hold system problem Electric parking brake system problem , parking brake not available

Sudden Loss of power. All warnings on. Limp mode only. Brought to dealer with brake system problem message. Restarted hours later and okay with no codes. Now worry on freeway about being rear ended if it happens again. Went from 70 to 20 all at once.
