Most recent incidents on Friday 08/07 car lost power while driving on freeway unable to accelerate, all engine/warning lights came on was thankfully able to pullover and shut off vehicle. This is not first incident this also happened about 5x in 2025 and had car inspected and serviced by Honda dealership each time being told they didn’t know what the issue is because the engine light wasn’t on at time of appointments. Final visit resulting in them adjusting the intake valves but they were even unsure if this was the correct “fix” well it did last a year without other incidents until recently, there seems to be a recall on 2023+ models but not my 2021 and this seems like may be similar issue. 12v battery and spark plugs are new, car is regularly maintenanced and have been told alternator is still good. Unsure where else to turn as I no longer feel safe driving this vehicle especially with my children. Where I live and work is almost impossible to avoid freeways.

On 2-252026 my wife and I were driving on highway I-15 in California when the car started to accelerate, decelerate and jerk and the engine light came on. It was very scary because we were on a major highway driving around 60 MPH and cars were behind us when the deceleration happened. We could have been hit by cars traveling behind us or either we could have caused a major accident. We had to get off the highway and have the car towed to Honda for assessment. There was no engine light warning or service warning from Honda prior to this happening, it just randomly happened. The car was repaired at a Honda dealership and they said there was a leaking head gasket on cylinder number 4. When we looked up information regarding this head gasket failure we saw that other Honda cars have had the same problem and Honda is currently involved in lawsuits regarding this leaking head gasket on cylinder number 4.

While driving on the highway at approximately 65 mph with my child in the vehicle during rush-hour on May 21, 2026, my 2018 Honda Accord Hybrid Touring (105,746 miles) suddenly dropped speed, and began backfiring and stopped responding to the gas pedal. The check engine light flashed and the vehicle ran rough. I activated emergency flashers and drove slowly to the shoulder. Sunnyvale Honda (Sunnyvale, CA) diagnosed coolant intrusion into one of the cylinders and head gasket failure. The vehicle had never overheated and showed no prior warning signs. All maintenance was performed at Honda dealerships per the maintenance minder schedule. The dealership performed a head gasket repair costing $7,500+ out of pocket. On the first highway drive after pickup, again with my children in the vehicle, the identical failure occurred: backfiring, complete loss of throttle response, vehicle unable to exceed 48 mph with the accelerator fully depressed. The repair did not resolve the defect. The vehicle is currently back at the dealership for further investigation. This failure created an immediate safety hazard on both occasions: sudden loss of speed on highway with no warning. Honda Customer Service denied goodwill assistance. I am aware of numerous similar complaints involving coolant leak and head gasket failure on 2018-2022 Accord including complaints documenting the same failure on the Accord Hybrid 2.0L engine. the federal safety agency should investigate this as a potential safety-related defect affecting multiple Honda engine variants.

Description of Incident: 1. Component/System Failure: The engine cooling system and head gasket failed. A certified shop has confirmed coolant intrusion and a failed leak-down test on Cylinder 2. The vehicle is available for inspection upon request. 2. Safety Risk: My safety and the safety of my family and other drivers were put at extreme risk. On March 1, 2026, the vehicle suffered a sudden loss of motive power while traveling at 70 MPH on the freeway. The car dropped to 15 MPH instantly, forcing me to maneuver across active lanes to a narrow shoulder with almost no space. I was nearly hit by high-speed traffic. This has occurred over 8 times since 2023. 3. Confirmation by Service Center: The problem has been reproduced and confirmed by an independent service center On Site Lube Auto & Tire. They utilized a borescope and leak-down test to verify the internal engine failure. 4. Inspections: The vehicle has been inspected by a certified independent technician. I am in the process of notifying the manufacturer (Honda) of these findings for their inspection and accountability. 5. Warning Lamps & Symptoms: Prior to the total power loss, the vehicle displayed engine temperature warnings and "check engine" lights. These symptoms first appeared approximately 8 months after purchase in 2023 and have progressively worsened, leading to the current engine failure. 6. Additional Notes: This failure is identical to issues cited in active class-action lawsuits regarding Honda's engine defects, affecting both standard and Hybrid models. I am communicating via written report/email for documentation and accessibility purposes.

Over the past several years, there have been multiple instances where I or my wife are driving on the highway and the engine light comes on or starts flashing, and I am unable to go faster than 50 miles an hour, and the engine itself feels to be underpowered. We have taken it to the dealership for repair at least five times over the past five years and in each case they have attempted to do a repair and said the issue has been resolved, but the issue continue. At at least one of those visits, they have diagnosed the issue as an engine misfire issue. The issue has intensified from the initial symptoms, (which were as I described, but resolved by turning the car off, waiting 30 seconds to a minute and then turning the car on again) to how it is now: in addition to the check engine light, every other light and warning system has gone off when driving on the highway and the engine was unable to go faster than 40 miles an hour, and it does not resolve by restarting the car. The dealership and Honda America’s main phone line have as of yet been unable to give me a clear answer as to why this is happening or whether it can be fixed. A sudden drop in speed and power on the highway as we have experienced many times over the last five years is inherently extremely dangerous.

While I was driving down the road with my foot on the gas pedal, without any notice whatsoever, my brakes began to jitter/shake and my steering wheel got stuck/tight and would not move. At this point, my car immediately makes a complete stop in the middle of the road and warning lamps appear such as; brake system problem, engine light, etc. I immediately turned on my hazard lights so cars behind me would go around me. Luckily, I was close to a curb and tugged on my stiff steering wheel and managed to park my car alongside the curb on the street. I called the Honda Dealership and they said my car was unsafe to drive and needed to be repaired. I immediately took my car to the Honda Dealership to get repaired. This malfunction could have caused an accident putting myself and others safety at risk as my car made an immediate complete stop on it's own and my steering wheel got stiff/hard to move making it hard to steer. There were NO warning lamps, messages or other symptoms of the problem PRIOR to the failure.

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.

At approximately [XXX]. Pacific, I was traveling southbound in the fastrak lane of the [XXX] departing from Pleasant Hill, California headed to Pleasanton, California. As I began to accelerate, the engine began to sputter. Immediately, the check engine light flashed on, then the dashboard reported a number of issues ranging from brake failure, TPMS failure, power assisted steering failure, vehicle stability assist failure and a number of other issues that I have never encountered since purchasing the vehicle. The sudden deceleration almost resulted in other cars impacting my car as this occurred during the morning commute. I was able to safely navigate off of the freeway. I was on speakerphone with Honda when this occurred. Had I not acted swiftly, a potential high speed rear end collision was likely to have occurred. I immediately took the car to Concord Honda. The team at Concord Honda performed a diagnosis and advised me that my head gasket was leaking water into the combustion chamber which resulted in the sudden loss of power. I was and continue to be dissatisfied with the handling of this issue by Honda as my car has never been handled by another mechanic. My car has a perfect or near perfect maintenance record and should not have a blown head gasket at 80k miles especially since my car is meticulously maintained and serviced by Concord Honda.
