I was driving my 2021 Honda CR-V hybrid touring at approximately 55 mph on [XXX] near the [XXX] exit. The vehicle had been operating normally. Approximately 115 miles before the incident. I had filled the vehicle with gasoline at BJ's in [XXX]. At approximately 11:50 am on XXX, the malfunction indicator lamp (check-engine light) began flashing while I was driving at highway speed. At the same time, the vehicle began smoothly losing power and slowing down. There was no shaking or rough running. I immediately pulled over, activated my hazard lights and turned the vehicle off for approximately 8 minutes. After restarting the vehicle, the malfunction indicator lamp was no longer flashing and the vehicle drove normally. I did not notice any other warning lights or dashboard messages during the incident. I am reporting this safety issue because the incident appears similar to the intermittent loss-of-motive power condition described in the federal safety agency Preliminary Evaluation PE25016 involving Honda CR-V Hybrid vehicles. I understand that PE25016 is an investigation and that I am not asserting that my vehicle has the condition being investigated.There was no crash, fire,injury or fatality associated with this incident.I would like this incident documented as a safety complaint because the vehicle temporarily lost motive power while traveling at highway speed. The fact that the warning light disappeared and vehicle returned to normal operation after being turned off and restarted makes the problem particularily important to document and diagnose.

Traveling on 4 lane highway at 65 mph on slight upgrade-check engine light started flashing and vehicle started to shudder slightly and went into "limp" mode I think. Started to slow down with NO power. Turned on emergency flashers and was able to pull over without incident, although it was close to causing an accident with a tractor trailer. I shut the vehicle down and after 10 minutes, started it again> I was able to drive home another 45 miles without incident. This happened a week ago and so far it hasn't happened again.

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.

My 2021 Honda CRV has been at freeway speeds, all of a sudden starts flashing my engine light, acceleration quits working... and I have to try to navigate off the highway as my car is slowing down to turn the car off. This has happened SIX times. Once I turn the car off and then turn it back on, it resets. It's not logging an error code so the dealership can't figure out what is wrong. I have recorded it happening on my phone several times, as requested, and shared with the dealership. I also made Honda Corporate aware and was given a case number a year ago and have contacted them SEVERAL times and they continue to say they are reviewing it, but no action has been taken. It's terrifying. I have so much anxiety driving my car and can't believe I haven't been hit or killed at this point. I also found several other people with the exact same make, model and year doing the exact same thing and Honda has done nothing. No recalls, nothing. They have been aware of this for over a year and are not reacting. I'm at a loss what to do. The dealership admitted this is a serious safety issue, but said they can't fix something they can't figure out. Unbelievable! Also, I do have video recordings on my phone of this happening and shared them with the dealership and with Honda Corporate Customer Service. I don't know how to upload them here, but happy to share them.

Several times when I was traveling at highway speeds on interstates, the car would suddenly decelerate and the engine light would start flashing. Sometimes the car shakes as well. When this occurs, I am unable to accelerate and the car's speed slows dramatically. I have to pull off onto the shoulder, shut the car off, and then turn it back on to clear the problem. I brought it to the dealership several times and they said there was no error code so they couldn't determine what occurred. Finally, they test drove the vehicle and experienced this problem and fixed it. I'm unsure of what they did to fix it. However, a couple of months passed and it just happened again. I was traveling approx. 70 miles per hour in rainy conditions in the left lane of an interstate with a lot of traffic/tractor trailers. I had to maneuver to the shoulder and put my hazard lights on. It is EXTREMELY dangerous and given the sudden slow speed on a highway with a 70 mph speed limit, this could easily cause a serious accident. I am going back to the dealership on Monday but it is concerning that they thought they fixed the problem and apparently, the defect is still present.

On highway, engaged cruise control at 70 mph. Engine light came on, simultaneously with loss of power (pressing on gas pedal did nothing) and Apple CarPlay disconnect. We were near an exit and managed to drift off, at lower off-ramp speed engine again could respond to accelerator however was chugging very badly. Went to nearby oil change place. Mechanic there advised going straight to dealer a short distance further. Drove on to the Honda dealer, car still chugging and stopped the car until I could talk to the service person. When the car restarted it was no longer chugging. Service person diagnosed the following and said i basically needed a new engine: TECH SCANNED VEHICLE AND FOUND CODES P0300 RANDOM CYL MISFIRE, P0302 CYL 2 MISFIRE. TECH CHECKED LIVE DATA AND HAD VERY LITTLE MISFIRE COMING FROM CYL 3, PULLED ALL COILS AND PLUGS AND FOUND CYL 2 AND 4 HAD THE INJECTORS STILL SPRAYING WITH THE VEHICLE OFF INDICATING FAILURE OF THE INJECTORS IN THOSE 2 CYLINDERS, IN CYLINDER 3 TECH FOUND EXCESSIVE OIL BURNING ON THE PISTON, INDICATING OIL LEAKING INTO THE COMBUSTION CHAMBER OF THE MOTOR.

On January 15th while driving home with my son I attempted to accelerate around a truck when I hit approximately 60 mph the vehicle stopped accelerating and began to slow down. I did notice that the "charge bar" for the hybrid battery was indicating that it was charging. The car continued to decelerate and I pulled to the side of the road. The check engine light was flashing. I turned the vehicle off for a minute and started it back up. The car drove fine and I was able to make it home. The dealership said there were no codes saved and they had no explanation. This was a the third time in the past year this has occurred and no one can tell me what the codes are or how to fix it.

Driving on highway, engine light began flashing, then deceleration occurred. No response in pushing the gas pedal at all. Pulled to side of road. Stopped car. Had it towed to Honda dealer. At the dealership, the car ran fine, the problem could not be replicated and there was no record that it had occurred. Approximately five weeks later, the same problem occurred on the highway, but I immediately got to the side of the road when the engine light came on and was able to pull off as deceleration was occuring. Waited a few minutes and the car then ran fine.

This is the 3rd incident with the same issue. I lose power when on a freeway. (Other dates [XXX] and [XXX]). On [XXX] I entered [XXX] and had accelerated onto the freeway. Shortly after getting on the ramp, my check engine light went on/blinking and I couldn't accelerate anymore. I was able to pull over on the shoulder. I turned the car off, waited a minute and then turned it on again and the issue went away. This is the same scenario that I've experienced twice before. I am rarely on freeways. On [XXX], I was on an incline with curves and very little room on the shoulder. This was a very scary incident for me. All of these incidents shouldn't happen and it is VERY dangerous to lose power unexpectedly when driving on a freeway. Looking on the internet for a solution - I found several other posts on what sounds to be the same issue and unfortunately didn't find a resolution. [XXX] [XXX] [XXX] Please review this as this is unsafe. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
