2021 HONDA CR-V Forward Collision Avoidance Warnings Problems

Driving down Piedmont Road in Atlanta on an overcast morning with no pedestrians, obstructions or vehicles in front of the car, the collision avoidance and braking system engaged for no reason and almost caused the car behind mine to run into me.

Dear NHTSA, There needs to be an immediate recall on this (VIN#: [XXX] ) 2021 Honda CR-V Hybrid Motor Nightmare. Despite proper maintenance and care, the vehicle has experienced persistent problems that stem from known defects. The engine has a fatal flaw with the head gasket. The high compression turbo engine stretches the head bolts, lifts the cylinder head just enough to blow the gasket causing coolant to leak into the cylinders and mix with the oil and destroys the bearings. Along with oil dilution where gas washes pass the piston rings. This is a widespread problem affecting this model as indicated by the numerous technical service bulletins. The issue appears to occur during the 20,000 to 30,000 mile mark where it begins to experienced recurring engine performance issues, misfires, loss of power, and excessive radiator fluid consumption resulting in premature engine wear and sludge buildup. Honda sites have pointed...

About a year ago, I was driving at speeds of approximately 10-15 mph when my car braked and immediately brought me to a dead stop despite no obstacles being present in the roadway. It appears the automatic emergency braking system malfunctioned. Had there been a car behind me, it likely would have caused an accident. On August 15, 2025, I was driving on the freeway using the adaptive cruise control when traffic in front of me slowed, engaging the automatic emergency braking. Traffic in front of me cleared almost immediately but my car was still very rapidly decelerating. I pressed the gas pedal, but the vehicle continued to bring me to almost a complete, immediate stop on the freeway (I had been traveling at 70-80 mph prior to the stop). I feel incredibly fortunate that I did not end up in an accident due to the traffic behind me and...

I am reporting a serious safety issue with my 2021 Honda CR-V involving the Collision Mitigation Braking System (CMBS). On multiple occasions, the vehicle has applied the brakes suddenly and forcefully without any obstacle or vehicle in front of me. THIS HAD HAPPENED OVER 20 times since i bought the CAR on March 10 2024. The most recent incident occurred while I was driving at highway speed on a clear, dry day. The CMBS system engaged abruptly, causing the car to decelerate rapidly and SLAMED BREAKS automatically. There were no vehicles, pedestrians, or obstructions ahead. This unexpected braking could have easily resulted in a rear-end collision, endangering me and other drivers. I have kids in the back sit and the car behind us almost hit my car. I am afraid the result might have been much worse if there was TRUCK behind my car. I took the vehicle to the...

1) On 3 occasions the Automatic Emergency Braking (AEB) has self activated and the car attempted to come to a complete stop. The 1st incident, 10/19/24, happened while driving 35-40 mph while changing lanes, a red BRAKE light and alarms sounded bringing the car to a complete stop. While there was traffic around me, no one was directly in front of me or close enough to have required this to activate. A vehicle traveling behind came inches from rear-ending me. The 2nd incident, 11/9/24 concerns me the most, happening 3 weeks after the first incident while on the highway traveling 65 mph. I was in the left lane of multi-lane traffic. While there were vehicles two lanes to my right, there was no one directly in front of me by 100 yards. Again, alarms, red BRAKE light, and the car proceeded to come to a complete stop. The car felt...

The car's forward collision warning system is defective. The car will randomly bring up "BRAKE" on the dashboard with nothing even close to the car. This has started happening many times over the past few weeks, with even at least one instance of the car braking on its own. I brought this up to the dealership during my last oil change recently, and they inspected and looked into it. They said there was nothing wrong with the sensors/system and they documented it (specifically saying no problem found vehicle is operating normally at this time). However, a day or two after the dealership, the problem returned and it continues to persist. In addition to this, the blind spot warning system also randomly goes off when nothing is nearby, but not as often as the braking system, which is more dangerous in my opinion.

The forward collision warning and braking has activated a couple of times without any car front of me for a wide distance or when everything is all clear. It also happened a couple of times when turning a curve or exiiting, also without any car in front of me. The only thing I could notice was the dashboard flashing but I could not read it because I had to focus on the road.

My vehicle lost brakes as I was driving. The dealer stated it was because of wiring problem but I read where crv were having a problem with the accident mitigation system. They replaced my wiring harnes to my rear view mirror. The dealer couldn't explain why I lost power to my brakes.

Interior lights switch does not seem to work properly. It started a couple of months ago. I have had issues with the automatic braking when the car "thinks" there is something in front of me and slams on the brakes. 4 out of 5 times there was nothing there. 1 of those times was during a rain storm, so that time I chalked it up to the radar being wet. I have also had several instances when the car flashes "BRAKE" when there is no reason for it. Similarly, when in reverse, the car again "thinks" there is something behind me and beeps when there is nothing within 50 feet of my car. I keep my cameras and radar clean at all times. Before each trip, I wipe them clean.

I was driving going about 30 in town and there were no cars, no pedestrians, no obstacles and all of a sudden my car's dashboard flashed brake and my car braked itself. We went from 30 to zero with a screech. I did not touch the brake during this time. It was unnerving and nothing like this has happened before. I commute on the freeway regularly and I am very scared this could happen at much higher speeds with deadly consequences.

Since purchasing the car new, there have been four instances in which the collision sensor has falsely detected object of vehicles that are no where in sight. The "BRAKE" warning flashes and then the car brakes hard, sometimes to a complete stop when no object/car are beside/in front of me. These have happened going at speed between 25-50mph. This is very dangerous because anyone behind could collide with me from behind and put my family in danger. These event happened at 10,000 miles. 20,000 miles, and up to 60,000 miles.

The front windshield camera was deemed it had faulty parts by the dealer and the car is less than two years old

This has occurred several times recently. Driving at 30-40mph also at highway speeds. Nothing in from of vehicle for at least 1/2 mile. Collison Mitigation Brakjng System activates without any warning. If it were not for seatbelts one would be sent into the dashboard or steering wheel. It is a very disturbing feeling being basically jerked forward unexpectedly. Luckily no one was close enough behind to initiate a rear-end collision. Currently we are waiting to have the car seen by our dealer. The dealer seems to treat this as a big deal since we can't be seem until the first week of July. I would think this issue would be one of a very serious safety concern, but I suppose the dealer feels not. They did however tell us to turn that system off. Seems counter intuitive to have a safety system yet told to turn it off and wait...

You have 87 complaints about the Forward Crash Avoidance / Braking System for this vehicle. Since my previous complaint, (#11470565) this unsafe, DANGEROUS, condition has occurred on two additional dates. Nearly all of the complaints that I read, mention the same issue: you are driving along and the system forces the vehicle to brake to a stop or nearly to a stop, NEARLY causing numerous rear end collisions. It’s scary and DANGEROUS.

I was driving on State Road 426 in Florida at 40 MPH. The weather was cool and sunny with light traffic on the roadway on both sides of the median. Suddenly, the vehicle “Hard-braked” on its own while my foot was on the gas pedal. The brake action lasted about two seconds and luckily the car behind me was not following too close or it would have rear-ended us.

My car has done this phantom braking multiple times before, however this time it managed to pull my car into a curb and pop my brand new back tire and ruin my front tire. This is a huge safety issue because if there was anyone in front of or behind the car could’ve caused a major collision. I have done some research and noticed this has been an issue on previous years of my vehicle. I feel unsafe driving my car and my dealership has basically told me there is nothing than can do and that is not acceptable with me. The fact that my life was put in danger due to a malfunction with the forward collision warning is absolutely ridiculous. I will probably never buy another Honda if something is not done to correct the issues.

This has happened approximately once a month since i got the car and i've had the car for 13 month. When using adaptive cruise control on the freeway going at least 60, the car will randomly give me a forward collision warning. Sometimes the car slams on the brakes, and other times the warning goes away after about a second. I can override it by pressing on the accelerator. This always happens when theres no cars anywhere near the front of me. The car has not been inspected by the manufacturer because the problem cannot be recreated on demand. its very infrequent. Other than that the car has had no other major problems.

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.

While driving on a highway at approximately 60-65MPH, the vehicle in front of me began to brake. I was a safe distance from the vehicle in front of me. I also started to brake, but allowed the gap between us to close somewhat due to a vehicle following closely behind me. The Honda’s emergency braking system suddenly took over with MAXIMUM braking, causing items in my vehicle to fly around AND the vehicle behind me to nearly rear end me. I had NO control over the braking. My wife screamed at me, thinking that I had slammed my foot on the brakes, but it was beyond my control. I’ve asked my Honda dealer if the system can be adjusted but I was given no help. I understand the emergency braking system’s intended purpose, but the manner that this system has engaged (3 times) is unsafe. It’s not like I wasn’t...

Slowed down to go across a metal plate where work had been done on the street. Suddenly the car came to a hard stop. There was a car in the left lane that also slowed to cross the metal plate. Once before I was rounding a curve and the car softly broke on its own, but didn't completely stop. There was a car again in the left lane. had the car behind me been closer, I would have been rear-ended. There was also no cars in front of me at both times. The warning collision light did come on and beep. I did call the dealer, they check for recalls and there were none. No inspections have been done. I plan to take it to the dealer for inspection.

On more than one occasion while driving the touch screen went black couldn’t access my navigation nothing couldn’t get the screen to turn on it wouldn’t do anything. Then it will tell me connect device when my phone is plugged in I’ve changed the cords replaced them with generic apple cords nothing bought apple cord and still nothing, apple car play doesn’t connect says you need to unplug device for car play to work nothing. The sensors are not working like they should there will be nothing around the car will alarm brake then it will automatically brake. I should not have to at to replace the touch screen in my vehicle it’s under warranty well under the miles as well. I work at a car dealership and the touch screen issue is a big problem I get several complaints about the touch screens not working.

My 2021 Honda CRV is activating the brakes at inappropriate times. I've had 5 total instances that could have resulted in a rear-end collision both on the street driving 5-35 mph and freeway at 30-50 mph. The system on the dash board flashed "brake." However, there is more than a car space between the car in front of the car. The braking system activates and I am unable to counteract the brakes locking up on the car. I am very concerned that if I were to continue to drive my car , it may result in an accident with a car crashing into the back of my car. At this time I am waiting for the vehicle to be inspected.

Purchased car on July 7, 2021, that same day the car did not start when stepped on brake and pushed start button. Happened again on July 8, 2021. Called Dealer, Took it in on July 9, 2021. They could not duplicate problem. Assured me it was not a problem. Drove to CT on July 10, 2021, Did not start several times during the trip. On July 11, on return trip from CT a warning light came on dashboard. IN black letters in a red rectangular box - BRAKE. I called dealer on Monday July 12, 2021 and reported the warning. He said it meant there were cars in the way. The BRAKE IN A BOX occurred 2 more times (8/6 and 8/17). I called dealer who said it was not a problem. I subsequently searched the warning on line and it says "BRING YOUR CAR TO A DEALER. TO CONTINUE...
