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.

2023 and 2024 Hybrid Accord vehicles liberally activate brake lights while cruise control is active under even the slightest level of deceleration creating an appearance of a “brake check” when there is no brake check. A traditional car’s cruise control, for instance when set to 60MPH allows you to depress the accelerator, speed up to 65MPH to pass a vehicle, and then release the accelerator. The car then slows down naturally and begins controlling at 60MPH. The deceleration is gentle and the brakes are not applied and the brake lights do not illuminate. The accord hybrid under the same conditions will apply some level of regeneration to slow the vehicle and also activate the brake light to vehicles behind. While it’s understandable that the brake light would be illuminated if substantial regeneration is being applied, the brake light illuminates under even the slightest deceleration creating an unnecessary hazard. This can occur if the car is slowing down from only 2MPH above the set point. Brake lights illuminate although the amount of regeneration being applied is negligible. It can also happen coming over the crest of a hill on a gentle downslope even with no prior depression of the accelerator. This is a serious deficiency and incorrect behavior. The brake lights should only illuminate under substantial regeneration or application of the brake pedal.
