Honda Accord Hybrid warning lights comes on

Filed Oct 16, 2026 · Electrical, Engine · NC

On October 12, 2026, my 2024 Honda Accord Sport-L Hybrid experienced a serious and potentially dangerous loss of propulsion while driving. Without warning, multiple warning lights and system malfunction messages appeared simultaneously on the dashboard. The vehicle then switched to electric-only (EV) operation, and the gasoline engine was no longer providing propulsion. I continued operating the vehicle using the remaining hybrid battery charge. As the battery charge decreased from approximately 1–2 bars to empty, the vehicle lost its ability to propel itself and eventually came to a rolling stop. After stopping, I turned the vehicle off and restarted it. The vehicle subsequently resumed normal operation, and most of the warning lights disappeared. However, the emissions system warning remained illuminated. After researching this incident, I discovered the federal safety agency Safety Recall 25V785000 (Honda Recall TN2), which affects certain 2023–2025 Honda Accord Hybrid vehicles. According to the recall, a software error involving the Integrated Control Module (ICM) may cause the system to reset while driving, resulting in a loss of drive power. The symptoms described in this recall closely resemble what I experienced. However, when I contacted Honda, I was informed that this recall had already been completed on my vehicle. I am extremely concerned that my vehicle experienced a loss of propulsion despite Honda reporting that the applicable safety recall remedy had already been performed. This incident presents a significant safety risk, particularly if a similar failure occurs while traveling at highway speeds, navigating an intersection, or driving in heavy traffic. I am requesting that the federal safety agency investigate whether the existing recall remedy adequately addresses this potential safety defect, whether the software update was properly implemented, and whether other Honda Accord Hybrid owners have experienced similar failures after recall completion.

While driving ~70 mph on highway on adaptive cruise control, the car suddenly LOST ALL POWER/ACCELERATION, including POWER STEERING and ALL WARNING LIGHTS FLASHED ON THE DASHBOARD. I recalled some were BREAK SYSTEM, ACC, ABCS, CHECK ENGINE, POWER, TPMS...etc. Essentially any warning light Accord has was flashing. The car slowed with no power steering, I managed to parked on the shoulder and turned on hazard light. This is extremely dangerous as the highway traffic was extremely heavy. After I parked, I pressed the ENGINE START/STOP button thinking I needed to "turn it off" but the car already had lost power at that point anyway. After pressing it a couple times, the car restarted and I drove to the dealer with one error message remaining on the dashboard - "Emission system problem. Power may be reduced. See you dealer." and the CHECK ENGINE light was on.

Component/System that failed or malfunctioned: Power Train: automatic transmission internal (CVT). The vehicle stops responding to acceleration, remains static while the engine continues at high revolutions, without generating forward movement. The component is available for inspection upon request. How safety was put at risk: The incident occurred while driving on the highway. By losing acceleration power and not being able to maintain the required speed according to traffic laws, I was at risk of being struck by other vehicles traveling at normal highway speed. This situation posed an immediate danger to both myself and other drivers. Problem reproduction/confirmation: The dealership inspected the vehicle and informed me that, at this time, there is no safety bulletin related to my unit. Inspection by third parties: I have scheduled an appointment with the dealership for September 5, 2025, where a more detailed evaluation of the problem is expected to be performed. Warning signs or prior symptoms: When the failure occurs, several warning lights illuminate on the dashboard and then turn off. Timeline / first occurrence: The failure occurred on August 14, 2025, at 9,215 miles. Related campaign reference: There is an existing the federal safety agency recall campaign for the same vehicle model: the federal safety agency Campaign ID: 23V588000

Component or System Failed: The head gasket appears to have failed, leading to coolant leaking into cylinder 4. This has been confirmed by two separate service centers. The vehicle is currently available for inspection if needed. Safety Risk: The failure caused engine misfires and dashboard warning lights to activate while driving, which could have led to a sudden loss of power or control. I had to pull over and restart the vehicle to regain drivability, which put my safety and that of others at risk. Reproduced or Confirmed by a Dealer or Service Center: Yes. The issue was first diagnosed by Honda of Sumner, who initially suspected a compression issue. Their master mechanic later confirmed it was likely a head gasket failure. A second opinion from Greg’s Japanese Auto confirmed the diagnosis and provided photos showing coolant in the cylinder. Inspected by Manufacturer or Others: Yes. The vehicle was inspected by Honda of Sumner and Greg’s Japanese Auto. No inspection has been done by police or insurance representatives. Warning Lamps or Symptoms Before Failure: Yes. After a recent service (which included an AC repair, fuel pump recall, and oil change), I experienced two misfires in cylinder 4 within 24 hours. All dashboard warning lights came on during one of the incidents. These symptoms began four days after the service. Additional Context: I was quoted $8,100 for the head gasket repair by Honda. I believe this issue could have been detected earlier during the diagnostic service. I’ve since learned of a class action lawsuit involving this exact issue in my vehicle’s generation, which makes me concerned this is a known defect.

While diving at highway speeds (first at 55mph in may 2025 and then again in July 2025 at 65mph) I got a warning on screen about power loss and a critical failure and that power will be reduced and to stop at the side of the road. Within 30 seconds or a minute of the warning the car power cut out significantly impacting the speed and both times almost causing traffic behind me to hit me from behind. I took it to Honda dealership in dulles, va back in may 2025 and they told me it was the electric water pump which I had replaced. Now in July it happened again and this time I had my wife and child with me in the car as well as a guest. I had to pull over and all the warning lights started to flash (everyone of them). I have taken it back to Honda but having a car that goes from 65mph to 25mph on the highway with no warning to others is a recipe for disaster. Apparently this is a known issue with the hybrid system and the battery needs replaced (from online honda forums) which Honda is not doing unless forced. I am still waiting for my dealer to get back to me but its exactly the same problem as the other notes I saw online. My car only has 46,000 miles.

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.

I was driving on the freeway and my engine lost power and all the lights on my dashboard went haywire. I tried to get off the freeway but with the loss of power made it extremely difficult and dangerous. I thought I was going to get into an accident since my car slowed down so abruptly. I had to limp my way across traffic which was very scary. The car was jerking and shaking. I finally got to the side of the freeway and the car did not want to continue so I called for a tow truck and waited on the side of a busy highway. The tow truck brought my car to the Honda dealership which diagnosed the problem immediately as a blown head gasket. They said it was a known problem and the mechanic knew what to look for. They fixed the head gasket and I have my car back. My car only has 92k miles and I don’t think the head gasket should fail this early in the vehicles life. I properly maintain my engine with routine oil changes. There is no reason the engine should break down like this. I feel that there is a defect in Honda’s head gasket.

Driving routine commute of 20 miles at Highway speeds on a clear weekday. The vehicle experienced ALL warning lights on dash and immediately went into limp mode. No power applied to the wheels when pressing the power pedal. Brought vehicle to the side of the road and powered off. Waited 30 secs to a minute and pressed Power and the only remaining error of "Brake System Problem" stayed up on the Driver display. Dropped vehicle off at the dealer, 3 miles from my job, to have them evaluate. After half a day the dealer stated "no problem found", "intermittent error". Now there is a known problem with late Honda vehicles with water intrusion into the tail lights and that in turn causes a short in the Braking system. I have noticed condensation in the tail light (Drivers side) but only a very small amount. Dealer stated they checked both tail lights and found no cracks or condensation. In my opinion my car falls into this category but dealer would not agree to a replacement assembly UNLESS they saw condensation in the tail lamp unit.

12/22/23: I was accelerating onto the highway when multiple error messages popped up on the screen related to brakes, emission system, power steering, and others. The car’s accelerator lost power and slowed to a stop on the side of the highway. The interior electronics didn’t lose power, and neither did power steering or power brakes to my knowledge. I restarted the car and the warning lights remained on, however the accelerator appeared to function normally. Honda was unable to diagnose or fix. 3/31/25: I was pulling out of a parking deck when the engine lost power (no throttle) at the same time that multiple error messages came on to the screen. I coasted into a parking spot (brakes appeared to work) and turned the car off. I turned it back on and all of the lights had turned off except a warning about the brakes and TPMS (I think). The engine appeared to work normally, and I immediately drove to the Southpoint Honda service center. 4/8/25: Recap from Honda: Your car had a couple issues, they're all related. The first thing you're complaining about the stalling condition that is a known issue. There's a software update that fixes that. So I got it in here to do the software update, but then I could not communicate to the vehicle. The can Gateway module was unresponsive, which the car will run fine without it. But then, I can't talk to the car. So after testing everything and finding the module to have failed, I replaced the can Gateway this morning. Everything's communicating fine and software is updating right now for the module. Then I'm going to update the pgmfi software for the ICM system to correct the communication loss within the network that causes the stalling issue. So those two issues will be corrected.

On 3 occasions, was accelerating on interstate (after entering from ramp), check engine light began blinking, car shook terribly & went into limp mode - gas pedal was to the floor but car continued to lose power. Had to pull off road - turned car off, waited 20 minutes, turned car back on - check engine light went off & car was drivable. Another time, while accelerating on interstate, check engine light started blinking & all warning lights came on flashing. Car began losing power - had to pull off on side of the interstate - car was towed to the dealership. Another time, was pulling off from a light on highway - I accelerated, check engine light began blinking, car shook terribly & went into limp mode, requiring me to pull off on side of the highway - turned the car off for 15 minutes - turned it back on, light was off & was able to drive car. Most recent incident - was accelerating on small, 2 lane highway - check engine light began flashing & car shook terribly but didn't go into limp mode - otherwise behaved as before. Each time, took the car to the dealer ASAP to report problem. First time, was told they had to fix broken tail light b/c it was throwing off system & they couldn't get a computer reading. Once done, was told that they got a "CYL2 Miss Fire Code. Performed diagnosis on code. Diagnosis led to improperly adjusted valves. Performed valve adjustment. Found half of valves loose and half tight." Was road tested - no further concerns noted by dealer. Other times, was told that computer wasn't showing any codes. Last event literally happened in front of Advance Auto - pulled in/hooked up to check code - indicated a Cyl 2 misfire. Took to dealer - said no code showing - berated me for having checked @ Advance - said it erased any codes, even though I told them the code that was noted. This is a serious safety issue due to car going limp when accelerating on interstate where others are going 70-90 mph. Dealer says nothing they can do d/t no code showing.
