While diving at highway speeds (first at 55mph in may 2025 and then again in July 2025 at 65mph) I got a warning on screen about power loss and a critical failure and that power will be reduced and to stop at the side of the road. Within 30 seconds or a minute of the warning the car power cut out significantly impacting the speed and both times almost causing traffic behind me to hit me from behind. I took it to Honda dealership in dulles, va back in may 2025 and they told me it was the electric water pump which I had replaced. Now in July it happened again and this time I had my wife and child with me in the car as well as a guest. I had to pull over and all the warning lights started to flash (everyone of them). I have taken it back to Honda but having a car that goes from 65mph to 25mph on the highway with no warning to others is a recipe for disaster. Apparently this is a known issue with the hybrid system and the battery needs replaced (from online honda forums) which Honda is not doing unless forced. I am still waiting for my dealer to get back to me but its exactly the same problem as the other notes I saw online. My car only has 46,000 miles.

At speeds between 50mph a howling noise begins and gets louder as the speed increases to 55mph. The howling noise is quite loud. It stops after you get above 55pmh or you open a window. The dealer said he was not aware of this problem.

FREON LEAKING FROM THE EVAPORATOR.

My car is a hybrid. At times, a Very loud humming noise is produced, due to glitch in software with the ANC. Noise starts and stops suddenly, intermittently, without warning, and is a safety hazard. Noise can build to be extremely loud and jarring, and can last for several minutes. Honda claims this is a cosmetic issue only and they are working on it. But the issue has been repeatedly reported by thousands of drivers over a multi-year period. Honda is ignoring any real resolution. Please help! This is frightening and disruptive, and makes operating the car unsafe. Thank you. It started about 1 year after ownership and was occasional. IT is now happening multiple times, every time I drive my car.

While driving at highway speeds (50 -55mph), the ANC (active noise control) unit delivers a loud Booming sound through the speaker system. The sudden and unexpected booming noise startled the driver causing temporary loss of control of the vehicle. The solution has already been identified in a Service Bulletin from Honda as Service Bulletin 21-053. The ANC unit has incorrect software and requires replacement to fix and eliminate the safety hazard. The issue was noted June 29th, 2021; but, has not been escalated as a Safety Recall. I have replaced the ANC as directed by the Service Bulletin and it has resolved the problem; however, other Honda vehicles have this same safety issue and if not Recalled will continue to be a safety concern for all drivers on our highway. I would like to see this escalated to a Safety Recall level and customers notified to replace. I am disappointed that Honda has not proactively Recalled this.

A loud booming / vibrating noise from the speakers while traveling between 52 & 54 mph with windows closed. Sound starts as a low noise / vibration and escalates to its maximum before abruptly ceasing. Noise / Vibration first noticed when taking car home after initial delivery 3/28/2020. Vehicle use was minimal (due to COVID shutdowns) and noise not noticed again until late fall / early winter of 2020. Vehicle was taken to dealer at regular service interval in February 2021 and problem was evaluated at that time. Vehicle has been evaluated once and microphone for Noice Cancelling system replaced. Issue subsequently returned. Vehicle going for second repair.

THEY REPLACED THE MICS AND MODULE WERE REPLACED WITHOUT RESOLUTION. HONDA ENGINEERING ADVISED TO REPLACE WITH A PART FOR A 2021 MODEL YEAR. AFTER BEING IN THE SHOP FOR 2 MONTHS THE PART WAS REPLACED WITHOUT RESOLUTION. HONDA ENGINEERING ADVISED THE DEALER TO DISCONNECT THE UNIT AND RETURN THE CAR TO ME WHILE THEY RESEARCHED. THERE STILL ISN'T RESOLUTION.

1. THE APPLE CAR PLAY FREEZES WITH THE ORIGINAL APPLE LIGHTNING CABLE 2. THE DRIVER'S DOOR CLOSES WORSE THAN THE PASSENGER DOOR. I HAVE TO PUSH THE DRIVER'S DOOR MUCH HARDER TO CLOSE IT. 3. THE ISSUE WITH THE AIR CONDITIONER. I'M USING AUTO 72 DEGREES AND DON'T LIKE TO PLAY WITH THE AC. 30-40 MINUTES AFTER WARMING UP THE CAR, THE AIR FROM THE LEFT AND RIGHT FRONT GRILLES BEGINS TO BLOW WITH COLD AIR, I FEEL COLD AIR ON MY KNEES. IF I MANUALLY CHANGE THE DIRECTION OF THE AIR ONLY TO THE FACE, THEN THE AIR IS BLOWING WARM. IF I RETURN THE AIR CONDITIONER TO AUTOMATIC MODE, I FEEL COLD AIR AGAIN FROM THE LEFT AND RIGHT FRONT GIRLS. 4. STILL HEAR LONG LOUD HUMMING SOUND WHILE DRIVING ON HIGHWAY 53 MPH FROM THE FRONT DOORS SPEAKERS I ASSUME, AND SHORT LOUD HUMMING SOUND WHILE DRIVING IN CITY AROUND 28-29 MPH.

THIS VEHICLE WOULD MAKE UNCOMFORTABLE NOISE AT A SPEED OF ROUGHLY 55 MPH. WHEN I WAS TRAVELING ON HIGHWAY AND CRUISE AT AROUND 55 MPH, THERE WAS A CHANCE THAT I CAN HEAR A NOISE BUILDING UP. THIS NOISE FELT LIKE ENGINE SPINNING AT 2000-3000 RPMS BUT I COULDN'T DETERMINE WHAT EXACTLY IT WAS. I AM SAYING 'BUILDING UP' BECAUSE THIS NOISE WOULD BECOME LOUDER AND LOUDER WITHIN THE NEXT FEW SECONDS, TO A LEVEL THAT MADE ME AND PASSENGER UNCOMFORTABLE. THEN I WOULD EITHER DECELERATE OR ACCELERATE A BIT AND THE NOISE JUST WENT AWAY ABRUPTLY. IT DIDN'T HAPPEN EVERY TIME WHEN I WAS AT 55 MPH, BUT IN MY RECENT 500 MILES I HAVE ENCOUNTERED 4 CASES, WHICH MADE ME FINALLY CONFIRM THAT THE NOISE WAS MADE BUS THE VEHICLE, NOT THE ROAD OR OTHER VEHICLES. I REMEMBER IN EVERY CASE OF ISSUE, I WAS PRESSING THE GAS PEDAL LIGHTLY TO MAINTAIN THE SPEED. *TR
