2024 Honda Accord Hybrid Electrical System Problems

I was driving on an expressway 355 on Friday July 25. It was raining hard. I slowed down and was getting ready to exit on 55 when the lights On the dash all started lighting up and telling me it required immediate attention at the dealer. The car would not accelerate. I was going slow and was able to idol to the space between 355 and 55. There were cars all around me. I put my hazards on and turned it off. I waited a minute and restarted it. Luckily it started and I was able to drive. This happened on an expressway during a storm I was terrified and worried that I would cause an accident by not being able to move the vehicle. This happened once before also while raining but was in a parking lot of a gas station. I took it in and they told me it’s the 12V battery. However was not failing while at dealer. This is a serious safety issue.

I applied the brakes and pulled up to a light and as soon as my car came to a complete stop all of the lights just started going off. The light turned green and I couldn’t accelerate anymore and almost got rear ended. I tried turning the car off but it didn’t turn off. Instead, it just made a clicking sound and I was able to accelerate and pull into a parking lot and I was able to turn it off and I turned it back on and it the brake system light stayed on. I drove to work and when I got to work I turned it off and turned it back on and the car is fine.

While driving on the highway multiple vehicle dash lights began flashing, including brake system, tire pressure, check engine; and the vehicle suddenly and completely lost the ability to accelerate. The car was clearly still on and in drive, but pressing the gas pedal had no effect. After turning off the car and restarting after a few minutes, the brake system alert persists. Car was towed to dealer out of concern for safety. The attached picture is after the vehicle restarted.

I was driving on a highway when the engine light came on and the car immediately started slowing down even though I was pressing the gas pedal. It flashed there was a failure of the brake system, collision mitigation braking system, road departure mitigation system, hill start assist system, and adaptive cruise control system. The check battery light also came on. The car decelerated on its own with brakes engaged. I had to choice but to immediately pull over and luckily was able to steer to an off ramp and into a parking lot.

I was driving a busy 4 lane street when the brake warning light came on. Car slowed down and I managed to turn off onto a side street. When I pushed the throttle there was no reaction. The car would not move. I shut it off and restarted then it would go. The Brake System Warning light was on. Said: BRAKE SYSTEM Brake system problem. Brake performance may be reduced. See your dealer. I drove straight to dealer, and they checked the car and cleared the codes. Could not find anything wrong. I was lucky to be able to get off busy street without incident.

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.

I’ve attached a known issues that you have for the 2023 Honda accord this is the same issue with my car 2024 I’ve been 3 times to dealer but they refuse to accept it because it’s a 2024
