2021 HONDA CR-V HYBRID Fuel/propulsion System Problems

The issue occurs seemingly randomly about once a month when driving on the highway. All of the sudden the car starts de-accelerating. Even if you push the gas pedal all the way down it doesn’t go. It just goes slower and slower and thank goodness I’ve been able to pull over every time. Once I shutdown the car completely and turn back on then I have power 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.

Engine overheating in short trips with full coolant and oil. My car is 4 years old and after years of mysteriously going into limp mode and no help from the dealer, I believe it has a bad head gasket. this started when the car was 3 years old.

I own a 2021 Honda CR-V Touring hybrid and have had 2 incidents of what I have learned is called sudden unintentional acceleration (SUA). I bought the car new and took possession of it in the spring of 2021. The first incident occurred Nov 14, 2023 when I was parking at a restaurant. I was slowly pulling forward into a parking spot where there were unattended cars on either side of me as well as in front of me. Suddenly, without warning, I was surging with full force into the minivan parked ahead of me as well as the front end of the car parked next to it. I slammed on the brake but not before I had pushed the minvan several feet forward. I did not know how this happened but, even though I knew that I had not stepped on the gas pedal nor had something interfered with it, I assumed that I must have done something to cause this accident. Thousands of dollars of damage was done to my car as well as the other two vehicles that were struck. The second incident was June 11, 2025. I was slowly advancing forward into a hotel parking space. There was a curb at the end of the space with some landscaping behind that. The landscaping had an uphill incline with some large evergreens about 8-10 feet from the curb. Once again, the car suddenly surged forward, jumping the curb, and accelerating into the evergreens. I slammed on the brake, feeling like I was putting my foot through the floor. This was an exact repeat of the previous incident and I am absolutely certain that I did nothing to cause this acceleration to occur. I was able to back out of the evergreens and my car does not appear to be damaged. Airbags were not deployed in either incident. I went on-line and there are numerous reports of similar incidents among CR-v owners but I do not see any recalls or actions taken by Honda on this problem. I intend to take the car to the Honda dealer in the next week. I fear the next incident may result in injury or death.

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.

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)

This is the second time this vehicle has randomly lost power / internal combustion engine stalled while driving on the interstate. Vehicle was traveling approximately 70mph steady for 10 minutes when the incident occurred. The combustion engine began to shutter and stalled, check engine light began blinking. Hybrid battery went down to zero and had to make an emergency departure off the highway with no power. Vehicle had to be powered off and powered back on to resume normal operation. Because the CELlight cleared the dealership cannot look up the fault and mark it as NPF. When I search this issue, it seems to be fairly common with the 2020+ honda hybrids (crv and accords). This type of power train failure / stall is extremely dangerous especially on highways with little or no warning and time to react. We are begging the NHTSA to have Honda do a through investigation and recall to remediate the engine stall failures on these hybrid vehicles ASAP as this is extremely dangerous for our family and other drivers around us.

I was driving my 2021Honda CRV EXL Hybrid on the Interstate in the passing lane. I am the original owner and bought it new in 2021. never had any problem with the car up to that day. I was in passing lane accelerating about 60-65 mph as I rounded a slightly hilly curve in the road when suddenly car started to slow down rapidly. I looked at the dash and could see it was decelerating rapidly, going down and down and slower & I had my foot on gas pedal to the floor ,yet the car kept going slower. I put on hazards& managed to get in slower lane, there was considerable traffic volume at the time luckily had room to move in to slower lane and ultimately into emergency shoulder lane, the car was only going about 10 mph even though I still had gas pedal pressed down as far as it would go. Managed to exit the interstate, still it would go about 10mph ,so drove it to a safe commuter lot about 1/2 mile down the road. Noticed then that the engine light was blinking on and off. Called Honda dealer and told them was having car towed to their business. Next day, went to dealer and told service rep the experience , they scanned the system and found these codes stored: P0300-P0302-P0303 MISFIRES. they then cleared codes and test drove and no lights came back on at that time and stated that the technician performed a visual inspection and found no issues at this time and performed A/F ratio function test and all cylinders passed. Service rep recommended to me that they would take car for a longer drive ,they drove it 28 miles & no lights came back on and no codes set, they state it was "all OK at this time & stated INTERMITTANT CONCERN".I took the car back to my home with great concern ,I don't have trust in the car for myself , family or any other people on the road wherever I would go, I want your agency to investigate .As a [XXX] who trusted the brand and invested lot of retirement treasure in this purchase, I request help for a remedy, Honda had no answer & that doesnt cut it INFORMATION REDACTED PURSUANT TO THE FREEDOM OF I

My vehicle on several occasions stalled and/or lost power. Stepped on the gas and no power. Both while using cruise control. One incident was not using cruise control.

The vehicle check engine light flashes and vehicle proceeds to lose power on the freeway. The first time it happened, I was driving on the lane next to the fast lane during commute hours and I could not accelerate fast enough to reach the slow lane and pull over to the side. Luckily, a nice person slowed down enough for me to change lane. My husband took the car to a Honda service center and they found nothing wrong with. Then it happened 3 more times on the freeway and we took it back to the dealer. They performed some maintenance and returned the car back to us. Then it happened again and we took it back for service. Again they tried to do some repair and returned the car to us. After about a week, it happened again. As I was getting on the freeway with my children in the car, engine light starts flashing and I cannot accelerate. Each time we’ve had to pull over, shut the engine off, wait for a bit and start the engine again to get it going. At this point we are afraid to get on the freeway and we stay on the slow lane as much as possible. We’ve taken the car back to the shop for the same problem 4 times. We are still waiting for the shop to fix it.

My hybrid vehicle lost speed on the highway while going approximately 60 mph. The engine light started blinking. The battery charge icon started decreasing. I was able to exit the highway and pull into a parking lot. After 20 minutes, my car turned on and the battery icon showed it was charged. I drove to the dealership and after having my vehicle in the shop for several days. I forwarded an article to my contact at the Honda dealership from Autoblog dated Dec. 7, 2022 about AWD Honda CR-V's loss of power. The article mentioned a "leaking differential." The dealership came back and said they couldn't find anything wrong.

While driving on the highway, my Honda CR-V Hybrid flashed an error for "12 Volt Battery Charging System Problem." I was stunned to receive an error on a vehicle with less than 2000 miles, and while my passenger was attempting to assist me in determining what to do next, the vehicle began to slow on its own. I was able to engage my emergency flashers and pull to the shoulder before causing a collision. I turned the vehicle off, and it returned to normal operation. After I made it home safely, I contacted the Honda dealership via their website to schedule an appointment. After engaging with them through the chat feature, my contact information was taken for a return call to schedule an appointment for review and repair. I was never contacted by the dealership.

While driving on the highway, my vehicle flash an error "Check 12 Volt Charging System. Power Reduced." Having received this error a few months prior, I immediately moved to the shoulder to prevent a collision.

Vehicle is advertised at "36-40mpg" (36 highway, 40mpg city). I am averaging (AT BEST) 25mpg. I reported the issue to Honda Corporate and they advised I take it in to a dealer. I took the vehicle into the dealer I purchased the car from and was told "we drove it around for a few minutes and everything is fine with it." The dealer advised there was "no problem" and "nothing they could do.
