2021 Honda CR-V Electrical System Problems

Auto-Restart is failing, causing car to stall or shut down entirely. When we pull up to a red light and the engine turns off, the car does not restart. Sometimes, it needs to be manually turned back on — sometimes, it shuts down entirely and requires a jump. Most recently, it required a jump and blocked traffic for 15 minutes on a busy street.

My dash board lit up and started dinging. Many different messages were flashing across the screen such as driver assist feature problem, TPMS problem, and others related to the electronic driver assist features. I noticed a difference in the way my car handled as I was pulling off the highway to a gas station to check my tire pressure. It seems drivable at the moment and I don't have another vehicle option. It's a 2021 CRV.

This has happened twice in a month. I was driving on the interstate and the check engine light began flashing. The engine lost power and would not accelerate beyond 40 mph. The situation was incredibly unsafe as both times I was on the interstate and had to pull over. The second time was at night and around heavy construction which increased the danger. On each occasion the light turned off and the problem fixed when I turned off the car and turned it back on. Both times I took the vehicle to the dealership and they were unable to find the code or any issues. On the second time they recommended adjusting the valves and replacing spark plugs. The vehicle has not been inspected by anyone else. There were no warnings prior to the flashing check engine and the car losing power. On both occasions this happened within ten minutes of starting the vehicle.

On two recent occasions over the past month, my 2021 CR-V Hybrid has lost motive power/check engine light flashing, with the while driving on busy interstate roads between 60-70 mph, decelerating in fast-moving multi-lane traffic. The dealership service department has not been able to fix the issue. I believe this issue is similar to others that the NHTSA is evaluating (PE25016). This issue could be very dangerous if a driver is not able to safely move off the road or shoulder. Please issue information to car owners and dealers on how to fix this serious issue.

Component or system involved: Electrical system / infotainment unit / audio system / driver-assist camera systems. Yes, the affected components are available for inspection upon request. Safety risk: The incident occurred at highway speeds, which created a potential safety hazard because the infotainment system suddenly shut down, the audio system emitted a loud “pop” sound, and driver-assist features became unavailable. The distraction and temporary loss of information could increase crash risk. Reproduction: The issue has not been reproduced yet and has not been confirmed by a dealer or service center at this time. Inspection: The vehicle has not yet been inspected by the manufacturer, dealer, police, insurance, or any other agency. Warning signs: No warning lamps or messages appeared prior to the failure. The issue started suddenly while driving. What happened: While driving at approximately 65 mph on a major highway with cruise control active, the infotainment system suddenly shut off for about five seconds. At the same moment, the audio system emitted a loud “pop” noise similar to a small explosion. After that, the screen restarted and remained stuck on the Honda logo for around two minutes. When it finally rebooted, the clock reset itself to UTC instead of the correct local time. All of this occurred while the vehicle was in motion, which created a distraction and potential safety concern. No previous warnings or symptoms were present before the event.

2021 Hybrid CR-V - within the last 10 months the vehicle has twice lost engine power while driving on expressways with just enough time to pull off the road. In the same period of time, at least 6 times, when initially starting the engine, the engine runs roughly and will not accellerate. So far, this has happened in cold or cool weather but not extremely cold weather. In an effort to restart the system, we then shut the system off, wait a few minutes and try restarting. Occaisionally, the engine will start normally after this "reset". More often, if the "reset" doesn't work, we shut off the heat/cooling system (to keep the system from calling for the engine power) and restart the system in EV Mode. The car will begin moving in EV Mode. The engine then starts and runs normally when accellerating beyond the EV system's capacity to accelerate. We understand this problem does not register in the car's computer as a "fault" once the car's engine operation returns to normal. Therefore, the dealers are unable to diagnose the problem. We have read of many other people having the same experience without any satisfactory correction from the dealerships or mechanics. Because this is an intermitant and unpredictable failure, and because the engine and system operates normally for long periods between incidents, the error must be computer/electrical and not related to the fuel pump. We have also replaced the aged engine battery and cleaned the cables. This did not correct the problem. Any assitance in resolving this issue is appreciated. We are concerned that the system will fail completely at the most inopportune time, leaving someone stranded on the highway or being a road hazard on a highway.

On 7/21/2025, the car smelled of rotten eggs. When I got home I checked the Honda website for recalls. There is a recall on the fuel pump for my type of car, but not with my vin number. I researched that if the fuel pump goes without repair it can lead to the catalytic converter needing replaced. So, I went outside to go get some dinner and the car wouldn't start. Everything inside flashed a few times and then went dead. This car is only 4 years old. I believe they've missed my car on their recall list.

Alternator failed suddenly at 24000 miles causing power steering to fail and vehicle yo just shut down in roadway.

I had 2 unrelated issues in the past 2 days: 1) rear door actuator malfunction. The door won't lock or unlock as part of the central locking system 2) The "break" alert went off without any cars around. Happened once, breaks weren't activated by the car.

The contact owns a 2021 Honda CR-V. The contact stated while driving at 40 MPH, the contact stated that the automated brake warning light would illuminate. The contact stated that the brake would inadvertently engage. The vehicle was taken to the dealer where the vehicle was not diagnosed or repaired. The contact stated while driving at an undisclosed speed, the vehicle lost motive power with no warning light illuminated. The vehicle was towed to the dealer where it was not diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 33,233.

Important safety recall unresolved. There are defects to the internal short circuit from environmental humidity. This issue may cause the airbags to deploy and increase the risk of injury. There is a limited supply of parts; according to the recall letter, the dealership confirmed the current status. I called the manufacturer's care program and was told there are no changes in the status of the recall being repaired.

With keyless transmitter in my possession…Intermittent Attempts to start the vehicle can be almost impossible due an extremely firm brake pedal with high resistance. First attempt.. extremely firm brake pedal with high resistance…pressing the start button… no results. Second attempt brake pedal will have a slight “give” .. pressing the start button only results in all dash warning/ inspection lights illuminating. Third attempt usually results in the vehicle starting normally. In an attempt to remedy the problem… I have replaced the start/stop button… problem still persists. Have read numerous articles and posts in forums and on the internet that other owners of various Honda models with the push button start switches experiencing the same issue. I have contacted my local Honda dealer… they state to date they have not had any customer reports of this problem … However… …. contacting an independent Honda repair shop reveals they in fact have had customers report this issue. When this happens… there is no warning… no illumination of DTC lamps on the dash… intermittent… but very concerning

The contact owns a 2021 Honda CR-V. The contact stated that while driving at an undisclosed speed, the contact became aware of a failure with the inclement weather sensor which should engaged with the vehicle in inclement weather. The contact stated that the sensor would not function properly. Additionally, the system failure warning light was illuminated. The contact was concerned of a safety hazard while driving in inclement weather. The dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 66,000.

Door Actuator and yes it is available for inspection. Yes, I was locked inside of the vehicle one time (recorded a video of it and showed it to Metro Honda service parts employee). No, the dealer did not conduct a vehicle diagnostic (the vehicle was over the warranty mileage by a couple hundred miles). No Police report. No warnings prior to the door actuator issues.

On multiple occasions, the information on the LCD, as well as the dashboard info/screen will start to flash over and over again, and then look like gibberish or just lock up. Sometimes it corrects itself, and sometimes I have to shut off the car for it to correct itself.

lane assistance problems too carmax went and authorized a once before recalled Pilkington windshield on my brand new honda purchased last year. Since the windshield has been replaced twice going on a third time in the next month . It has had calibration issues and durability issues from everyday small rock taps off the highway or street when driving. the honda fuel consumption is too fast when the AC is initiated the oil consumption is too fast between oil changes it has had roughly 4 oil changes when the mfg says the car should go 7k- 10k between oil changes

My 2021 sunroof shattered out of no where when i was driving, nothing fell on it and no cars nearby so it was not rocks. I think this should be looked into because there are many owners who have reported the same issue. I contact my local dealer and they were in denial but it is very dangerous since the glass from the sunroof was falling on me while i was driving it could have caused a major accident and should definitely be looked into. Sometimes when I turn on my car the dashboard flickers where you are not able to read the screen another safety concern if i cant see certain information. My car only has 8000 miles on it any my battery is still good so I am not sure why there is all these issues.

Model: 2021 Honda CR-V Hybrid VIN: [XXX] ]] Mileage: [78000 old motor | 25000 replaced motor] Issue Type: Engine Stalling / Rough Idle/ Low Operating Temperature / Warranty Denial Maintenance History: Dealer-maintained per schedule Dealer Name/Location: [American Honda Motor Co., Inc. Attn: Customer Relations / Warranty Department 1919 Torrance Blvd. Torrance, CA 90501] Manufacturer Contacted: Yes – denied assistance despite known issue TSB References (if applicable): TSB 21-013, TSB 22-087 --- Complaint Summary: I am reporting a known issue with my 2021 Honda CR-V Hybrid involving engine sludge accumulation and chronically low operating temperatures, which I believe are tied to a systemic design flaw affecting hybrid models of this generation. Despite proper maintenance at a Honda dealership, I was informed of internal engine sludge. The issue appears linked to the engine not reaching optimal operating temperatures—leading to oil degradation and sludge formation over time. This matches problems detailed in official Honda Technical Service Bulletins (TSB 21-013 and TSB 22-087), yet I was denied warranty support, even under a Goodwill request. Honda regional representatives and mechanics provided no meaningful analysis or assistance and defaulted to denying support without adequately addressing the root cause. This is deeply concerning, particularly since multiple owners nationwide have reported similar problems. I believe this issue poses a long-term reliability and potential safety risk and should be investigated. I seek resolution from Honda, including coverage of necessary repairs and full acknowledgment of the defect.

2 MONTHS AFTER PURCHASE I have a lemon with Honda CR-V year of car 2021 bought it in October of 2021. The 3-year warranty is about to expire. I have taken the car several times to two different Honda dealerships because they are the closest to my home and I don't have anyone to pick me up or take me back. They claim there's nothing wrong with the vehicle but lights in the dash come up every other day then disappear after several hours then return the next time, I use the vehicle. the vehicle also has an issue with the acceleration; sometimes I step on the gas pedal but after trying to drive the car, the MOTOR does NOT move faster but rather the force of the vehicle decreases and doesn't allow for me to go faster than 20 MPH. The odometer is also inaccurate; one month after driving the vehicle about 80 miles-the vehicle odometer increased around 10 miles. I only have about 9,877 miles that I’ve driven the car… I'M [XXX] and cannot drive and take pictures while I'm driving. I barely know how to use my phone. I get nervous, start to panic and my heart starts racing and I feel like I'm going to crash. I'm scared for my life and my grandchildren that I pick up after school and take them to their home. ive tried to upload documents but i keep getting an error...INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Twice while driving the FCW warning brake light flashed on the dash with nothing happening. One time the brakes actually engaged and flashed the brake icon on the dash for the FCW and stopped the vehicle in the middle of the road and luckily no one behind me and I didn’t get hit.
