2024 Honda Accord Hybrid

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 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 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.

I am writing to let you know that 10/2/2024 my 2024 Honda Accord Hybrid Sport had sudden loss of drive-line power while I was traveling on the highway at 75mph. I was able to safely coast/navigate to the shoulder and stop. Steering and braking systems were normal. The car would not drive or restart once stopped. A tow truck was called to tow my car to the nearest Honda dealer to be fixed. There were no warning lights or sounds prior to this incident. Dealer determined root cause of problem was PCM not communicating with charging system. The PCM was replaced under warranty and my car was ready for pickup 10/18/2024

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.

On June 9, 2024, while I was driving on the highway, my new Accord flashed a series of warning messages on the right side of the driver information interface (instrument panel). The messages that flashed and scrolled through repeatedly are listed below: Electric parking brake system problem. Parking brake not available. See your dealer. Blind spot information system problem. See your dealer. Hill start assist problem. Vehicle may roll upon brake release. See your dealer. Transmission system problem. Performance may be reduced. See your dealer. Emission system problem. Power may be reduced. See your dealer. Additionally, near the fuel gauge a red BRAKE light flashed and an amber BRAKE SYSTEM stayed illuminated. This is upsetting because I've had my new Honda Accord just over one month and have fewer than 1500 miles on it. UPDATE: I took my new Honda Accord Touring to my dealer and they examined it and told me a solenoid needed replacement. They ordered the part which took several day and replaced it. The solenoid replacement did not fix the problem and the service manager said my car needed a new transmission (eCVT). I was shocked such a new car would require such a radical repair. After waiting two weeks, my transmission was replaced. However, I'm not confident in my car. I read on NHTSA that 2023 Accord Hybrid had a recall for eCVT transmission replacement. My Accord Hybrid Touring is a 2024 manufactured in 3/2024.

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.
