2021 HONDA CR-V HYBRID Forward Collision Avoidance Problems

While traveling northwest at 37 mph, the automatic brake system engaged jolting the driver. The camera shows no objects in front of but there were two vehicles traveling southeast in the opposite lane prior to the brakes applying. There were shadows from trees. If there was a vehicle behind, and the driver did not react fast enough, this would have been a rearend collision. This is the third time that the automatic brake system engaged for no reason since we have owned this vehicle (Dec 2021) and each time it has been reported to the NTSB. In the past two cases, there were no vehicles or shadows from trees, since we were in the desert. The previous two times, the vehicle was inspected by the dealership with no defect noted (under warranty). There were no dashboard warning notices indicating an issue. The vehicle will be resubmitted to a dealership for inspection for this third incident (not under warranty).

I was driving the vehicle on route I287 and all of a sudden the break system got activated without touching any button and the car speed was damped down and as a result the car was pulled aside to see what had happened. The break system completely collapsed with a break sign on the dashboard appearing persistently which could not be deactivated or was not able to remove from the dashboard with several attempts made in restarting the engine. Due to the involuntary break activation on highway driving, my life as well others would have been in extreme danger and jeopardized the whole situation in continuing driving further. The car was towed on a flat bed to the the dealer The Honda Princenton, New Jersey for further investigation and got analyzed for the root cause and they suggested a fix of head gasket replacement, a major repair, asking us to fix the vehicle at the cost of 6000 dollars. Previously, I had driven several Hondas and never experienced break issues on the cars and we had invested in buying this time the Honda CR-V and what we went through this vehicle something like this is not fair for the customer has to go through a major repair on the vehicle at such a low milage of 127,000 put on the car which never was involved in an accident and driving the car on high way every day to the work place. We want a complete restoration of the vehicle at free of cost and get it certified and drivable safely on the road.

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 Saturday November 16th 2024 I was driving my Honda CRV hybrid year 2021 when about 7:10pm I heard a beep, beep, beep and at the same time the car suddenly breaked in the middle of an intersection; there was nothing in the forward path so I don't really know why the car stopped abruptly. After a few seconds I put my foot in the accelerator and continued to go. When I arrived home I reviewed the videos (I had installed front and rear cameras) and verified that certainly there wasn't anything in front of the car when it braked by itself other than a manhole cover. I was in the car with 2 friends, thankfully no other cars were behind me or coming in any direction otherwise this event would've been catastrophic. Now I am afraid to drive the car because this could happen again and have a different ending. Note: I have videos that show this incident

My family and I were driving down the road, in a gentle left hand turn when the emergency braking system suddenly activated, and our best guess is that it was due to a car well off the road in a parking lot at the same point. A tractor trailer, loaded heavily with electrical transformers was just behind us, and if not for the driver of the truck paying attention we might not all be here today. This has happened many times in other situations, sometimes maybe a dip in the road, sometimes and exit ramp will confuse it, and sometimes I couldn't even guess. So far none have been too bad, but this one was too close. I have attempted to talk to the dealership about it, but they aren't calling me back. I've asked for them to disable the system entirely. There were no warning messages aside from the normal BRAKE message it shows when it activates. In the manual for the car they went so far as to list scenarios where the system might malfunction, but the only way to turn it off involves remembering to bold the button every time you start it up, and hope you don't forget. My child was set to take this car when they start driving, but as is I don't want to drive it, let alone anyone else.

On or about Sep 25th 2023, automatic brake system invertedly activated while driving 40mph with no traffic. Dealership could not find any codes or errors. On or about Apr 01st 2024, automatic brake system invertedly activated while driving 40mph with no traffic. Dealership could not find any codes or errors. On or about Apr 03rd 2024, vehicle turned on all by its shelf with no key fob around. Open door and sat in driver's seat and about 15 second later, the vehicle turned off by its shelf. Step on brake, pushed start button and vehicle displayed "need key fob". Dealership could not find any codes or errors.

my vehicle suddenly stops without me pressing breaks or there being another vehicle in front of me . It’s unsafe and I’m afraid of getting rear ended

The emergency braking system reacts unexpectedly and unnecessarily. I see there is an investigation for vehicles up to 2019, but my 2021 has done this at least a dozen times since new. My experience seems to indicate that it's often related to a shadow on the road. Could be an adjacent vehicle or simply a large tree or building. It can happen with an asphalt repair that is darker than the surrounding road or even a wet spot. It would also seem to be more likely to happen when driving towards the sunset or sunrise. It nearly caused me to get rear ended this weekend. It stabbed the brakes hard for a shadow on the road with vehicles behind me. Please extend the investigation to the rest of this vehicle's production.

On more than one occasion, the vehicles automatic emergency braking system engaged unexpectedly. This occurred when there was no obstruction in front of the vehicle.

Automatic emergency brake activated and the vehicle came to a complete stop while approaching a railroad crossing. There was no traffic ahead. It was a clear day, around 8:45AM. There was no indication of a problem before or after the car stopped.

I was traveling about 17 MPH when my CRV braked suddenly to a stop on it's own. There was nothing in front of me. Thank goodness no one was behind me because the car stopped with no warning. I was also wearing my seatbelt, which was good because I was thrown forward. There was no prior warning and no lights or other indicators on now. After that the speakers made thudding sounds, were staticy and now the radio will not play. NOt sure what this has to do with the AEB system. The car still drives normal, but I am afraid it is going to happen again. I have made an appointment at the Honda Dealer for them to look at the CRV.

Vehicle will frequently brake at full capacity on its own for cars in the next lane of traffic. This has happened 3 times so far. All three times it was on a highway going at speeds of 60-70 mph. "BRAKE" flashes in big letters on the screen. There are no obstructions in front of me only in the lane next to me. Dealer informed me it is a known problem and there is no fix except to disable the safety features.

Vehicle will brake without application of the brake pedal when there is not an obstacle that requires automatic braking to avoid a collision. The vehicle will have “BRAKE” on the dash. This has occurred without anything in the lane in front of the occur and there have been several instances. The collision mitigation braking system is supposed is malfunctioning.

There have been several occurrences with my 2021 CRV hybrid where the car will start beeping and the word “brake” will flash on my instrument cluster for no reason at all. No cars in front of me at all. This has happened 40-50 times. However there are 4 occasions where the car actually braked suddenly and once to a complete stop and nearly caused a horrible accident. From 65mph to 0 like it thought there was something stopped right in front of me. Even though there were no cars in sight in either lane ahead of me. Luckily no one was right behind me, It could have been much worse. I want to just turn this feature off, and obviously it was a big selling point to me to buy the car so to have it actually cause safety issues instead of solve them is irritating to say the least.

2021 HONDA CR-V HYBRID. CONSUMER WRITES IN REGARD TO SOFTWARE ISSUES. THE CONSUMER STATED WHILE USING ACC THE VEHICLE WOULD BRAKE PREMATURELY. THE CONSUMER WAS CONCERNED THIS WOULD CAUSE A REAR-END COLLISION.

As my wife and I were driving downtown at about 20 mph on a regular city street with no cars in front of us, the automatic breaking system suddenly beeped and slammed on the breaks, giving us whiplash. There was clearly some kind of failure in the collision mitigation breaking system. Previously, the orange "BREAK" light sometimes came on the dashboard if you got too close to the car in front but it was always accurate--there always was a car in front of us. But this time it was really startling because there was nothing in front of us and it almost caused an accident because the car behind us obviously wasn't expecting us to stop suddenly. We have a 2021 Honda CRV hybrid and have had no other problems with it. We haven't had any maintenance on it in besides a bit of standard care (oil change, tire rotation) so I assume whatever problem it has has been there since the purchase (we are the car's original owner). Overall it was quite worrying.

We were driving at about 45-50mph on a 4 lane road (2 lanes in each direction) when the car in front of us moved to the right side of the road (bike/turn lane) to make a right turn. There was enough room for the other car to safely turn right without stopping or slowing traffic. The 2021 Honda CRV Hybrid braked suddenly as if to avoid a high speed crash. The collision avoidance feature was on (the car was delivered with the feature activated and it was never turned off.) The car forcefully slammed on the brakes, seatbelts locked up and the driver felt a pop inside the left shoulder blade and neck pain; later in the day, the pain radiated throughout the left side of the back, up to the neck / base of skull and down past the waist. The passenger seatbelt also locked and there were no injuries to the passenger. No passengers or children were in the back seat. The sudden braking caused the car behind the Honda CRV to brake and swerve, but no accident occurred. The vehicle has not been inspected by the dealership or others. Yes, the vehicle is available for inspection upon request. There were no warning lamps and no indication that this was going to occur. This is a serious safety issue and injuries occurred from a car safety feature when there was no imminent danger or collision that was actually needing to be avoided.

The car detected an forward collision in error and began to brake. Emergency warning came on with beeping. No object was in front of the vehicle. Was traveling approx 40 mph on city streets.

Driving my car in traffic there was a steel plate horizontally on the road painted orange. My car saw it as a potential collision and suddenly automatically applied full brakes and flashed collision warning on dash board. I almost was rear ended. Luckily I was only going 25mph. I called dealership and talked to service manager Jake. He advised that this is possible in normal operation. There is a disclaimer about this occurring in the owner’s manual. He also said there is no history of warning indicators so there is nothing to check to see if normal operations.

Nothing has happened yet. I want it on record that the implementation of this feature is dangerous. On P.497 of the 2021 CR-V Hybrid's Owner's Manual is the following warning: "Exiting a vehicle that has been stopped while the ACC with Low Speed FOllow system is operating can result in the vehicle moving withoug operator control. A vehicle that moves without operator control can cause a crash, resulting in serious injury or death. Never exit a vehicle when the vehicle is stopped by ACC with Low Speed Follow." The way this feature is implemented, the following scenario is possible: I'm driving in heavy traffic that stops for a long time. I absent-mindedly forget that the CR-V is still in ACC mode and get out of the car to see if I can see what is causing the delay. While away from the car, traffic starts to move, and before I can get back in it, the CR-V drives away. Were there a child in the car or an adult who didn't drive, there could easily be multiple deaths caused by a driverless vehicle speeding up to the current ACC setting (which could be a freeway-appropriate speed). Just off-hand I can think of multiple ways to prevent such a scenario, each of which takes advantage of existing systems: The ACC could--and should--automatically disengage and the transmission go into Park 1) when a door is opened; 2) when the driver's weight leaves the seat; 3) when the driver's seatbelt is unfastened. It should not be possible for a vehicle to drive away without a driver, and this possibility could--and should--be easily prevented.
