Honda CR-V Hybrid misfire problems

Filed Sep 1, 2026 · Engine · WA

One four occasions our 2020 Honda CRV Hybrid has started after sitting overnight in the greater Seattle area in the spring and summer with a rough idle. Within two miles of leaving our home at speeds of no more than 35 miles per hour, the check engine light began to flash. All four times, the rough idle and check engine light were accompanied by degraded speed responsiveness and the error cleared with turning the car on and off again. We have taken the vehicle to a mechanic twice and each time they couldn’t find any stored codes or replicate the issue. The issue continues to occur and seems to be getting worse. I’m concerned this will happen at high speeds and result in a total loss of power which will be unsafe.

2/19/26 My car lost power while accelerating up a hill at about 60mph and the car had been operating for an hour and a half or so. The car was shaking, running on reduced power and the check engine light was flashing so we had to pull over to safety on a busy road. The car was towed to the local Honda dealer. The dealer said the code was a misfire on cylinder #4 but once they restarted the car the error went away. They did perform multiple tests including a compression test on all four cylinders and a leak test, and the car passed them all. They were unable to reproduce the problem. They did swap the #4 coil so that if it happened again, we would have more diagnostic information. They recommended no further action at that time. On 5/11/26 we had the same experience, also while accelerating uphill, after about 30 minutes of driving, this time on the interstate which was very scary; reduced power, car shaking and check engine light flashing. We pulled over, turned off the engine, and sure enough, when we restarted the car, it started normally. When we went to the repair shop a few days later there were no engine codes showing. On 6/12/26 the same thing happened again. While going uphill, on the interstate, after a couple of hours of driving. This time, as soon as we got home, we used an engine code reader and saw code P0304 – Cylinder 4 misfire. On 8/13/26 Lehigh Valley Honda reproduced the problem on the interstate, going uphill and do not have a clear fix. They want me to spend $587 on a Valve Clearance Inspection and Adjustment that I think won't yield any result.

When driving the vehicle will lose acceleration and not allow me to accelerate. It feels like it wants to shut off. The check engine light will come on when this happens. I turn the car off and turn it back on and it goes back to baseline and lets me drive as normal. This has happened while accelerating to get on the highway from an on-ramp, at around 45-60 miles an hour and also at city speeds slowing down to a stop light. I notice some rough idling/shaking during idle at times as well. I have not taken it into the dealer yet because it started happening over the weekend when the dealer was closed. Vehicle has not yet been inspected by anyone. I do believe the first time it happened that an error message came on my dashboard but I'm not 100% sure. The check engine light definitely did though both times it's happened.

I am getting increasing frequency of cylinder misfire, so far cylinder 1 and 2, and the car goes to a limb mode and loose power. It happens during acceleration to a highway ramp. Engine lights and other many warning lights come on, the car goes into limb mode, I pull over and when I turn the engine off and turns back on the warning lights clear and the car drives normally until next time, to start all over again. I took it two Honda dealers at three occasions. Since the engine light goes off, and they cannot capture the issue, they are telling me there is nothing they can do. It seems to happen during a normal driving than sport mode. It is frustrating and dangerous situation. I thought I would report it, to save others from similar situation

Day after bought car, battery dead and all lights lit up on the dash when tried to start. Dealership gave a 256 point inspection and said car passed all elements. Jumped battery with a jump pack then battery started smoking and leaking fluid. Had dealership tow and diagnose problem, replaced the battery. Two days later started car on a cold day and check engine light started flashing and car went into limp mode. Would not accelerate on the highway past 35 mph during heavy traffic leading to unsafe conditions. Drove to service center at the dealership while still flashing and not accelerating. Dealership said it was a cylinder misfire.

While driving at highway speeds (60-70 MPH), vehicle showed blinking check engine light, indicating a misfire. Pressing the gas pedal did not provide power to the wheels, though the engine was still running and revved up. My safety and that of those around me was in danger due to my inability to continue to maintain speed. I had to coast while pulling over to the side of a freeway. I turned the car off and turned it on and the issue appeared to resolve itself with no light on the dash. Took the vehicle to an independent service center, who would not look at the vehicle since the error code would not show from a cleared code. Told me to hope it was a 1 time issue and to stop back by with the light blinking. However, this will not be possible since I get no acceleration when the issue persists. The issue has not been reproduced, nor do I intend to attempt to reproduce it due to the safety issues involved with losing the ability to accelerate while traveling at high speeds on the freeway.

Been dealing with an intermittent flashing engine light issue for the past 1.5 to 2 years. We bought this car brand new in 2021 and the first time this happened the car was barely 3 years old. Whenever this issue occurs, the check engine light would flash and the car would lose engine power (pressing down on the accelerator does nothing). Once stopped, we can hear loud knocking noises from the engine. Usually turning the car off and then back on resets the behavior and the car operates normally. However, this is a very dangerous issue as it sometimes happen on the highway. It took us almost 2 years to successfully pull the error codes because, for reasons we can't understand, Honda designed this error code to clear itself after 3 uneventful drive cycles (as told to us by two separate dealers). We took the car to the various shops multiple time and they were never able to reproduce or diagnose the issue. Finally we were able to get the codes pulled at an O'Reilly's right after it happened, and the codes they found were: - Cylinder 1 misfire - Cylinder 2 misfire - Random misfires We took it to a dealer afterward and they ran a fuel/air ratio test and said everything looked fine; then they examined the fuel valves and noticed they were all overly tight. They believed that was the root cause and adjusted them to spec; we had to pay $1000 for the adjustment because for some reason this was considered a "maintenance item" even though we have never touched the fuel valves and the car was not due for this particular maintenance item until 100K miles, so I don't understand why this shouldn't be covered under warranty. In any case, it turned out the fuel valve adjustments didn't fix the issue and it happened again, so the car's back in the dealership now. I found a bunch of similar complaints pertaining to this vehicle model, and it really deserves more. attention.

My 2021 Honda CR-V Hybrid has experienced three identical and dangerous incidents over a one month period beginning around 60,000 miles. Each time, while driving at highway speeds (60-70 mph) climbing hills or grades, the vehicle suddenly loses all acceleration power accompanied by a rapidly flashing check engine light. This creates an extremely hazardous situation as the vehicle cannot maintain highway speeds with fast-moving traffic approaching from behind, forcing emergency stops on busy highway shoulders where rear-end collisions become a serious risk. After each incident, turning off the vehicle and waiting 10+ minutes allows normal operation to resume, with the flashing check engine light disappearing. The malfunction involves the engine ignition system, specifically cylinder 4 misfiring as confirmed by diagnostic trouble code P0304 that I captured during the most recent incident. The suspected failing components include the ignition coil, spark plug, or fuel injector for cylinder 4. What makes this particularly dangerous is the complete unpredictability - no warning symptoms appear before each incident, and the failure occurs suddenly under specific conditions that are common in highway driving. Despite three documented occurrences, two separate Honda dealerships have been unable to reproduce the issue or confirm the problem. Both claim they find "no stored codes" even though I have evidence of the P0304 code. The codes appear to be cleared after turning the vehicle off and on. The intermittent nature and specific conditions required (sustained highway speeds while climbing grades) prevent typical shop diagnosis, yet this appears to be a widespread pattern affecting multiple 2021 CR-V Hybrids based on similar owner reports online. The recurring nature combined with the inability of dealers to address the root cause, creates an ongoing safety hazard. The vehicle remains available for inspection.
