2017 HONDA CR-V Forward Collision Avoidance Automatic Emergency Braking Problems

I was driving across a major intersection when the car slammed on the brakes for no reason. There were no shadows. I was not under a bridge. It is an overcast day. No direct sun. My safety was at risk because I could have been hit by oncoming traffic when I was trying to go forward.

Random problems since purchase with screen going out and emergency brake light either flashing for no reason and braking for no reason. In 2023 the brake system completely failed while driving. Honda dealer replaced fuel pump which helped for awhile. Now flashing brake warning for no reason is happening again. Fear the car will either start braking again for no reason or another system failure might occur. Afraid to drive the car.

Driving down a local road with a speed limit of 40 mph. The car suddenly braked and the BRAKE warning light show on the dashboard. No others cars were near me, in all direction. It was clear sunny/dry day. Had to accelerate to prevent car from stop. to s void a possible rear end crash.

I have had all warning lights go on disabled some options, gave me incorrect speed, (i ended up w a speeding ticket over that) made my vehicle go in limp mode ,didn't want to accelerate on highway, could have caused an accident I have a young child and was scared to even drive it. It turned out to be my fuel injectors which was very pricey and I had honda do the repair. I have seen a whole lot of people with this issue with the engine I have which is the 1.5 turbo. I think it should be addressed by honda and they should really be fixing the issue at no cost especially since they know the original injectors were faulty and they changed the part number. Hope it gets addressed on behalf of hundreds of thousands of these vehicles and not so happy honda customers.

I have had my crv suddenly brake on me on multiple occasions when absolutely no one is around to cause it. It’s created many of close calls and given me mild whip lash in the past. But yesterday it happened in a way much worse than ever bc I was on the interstate and it abruptly stopped (again no one in front of me or to the side) which jolted me and gave me some brutal whiplash and then it was locked up & wouldn’t go faster than 20mph!! I was in the left lane & I almost got hit by multiple people behind me & almost died! I had to drive like this for 3-5 minute (hazards on of course) until I could ‘safely’ pull over. Once i turned it off and turned it back on, it went back to accelerating normally. I have taken my car to the...

Collision Mitigation Braking System (CMBS) Is automatically warning and has engaged when no object is ahead. Seems to be picking up overhead/over roadway traffic signals and signage.

the CMBS activated when driving when no other vehicle was in front of my vehicle. the car came to a stop.

I am writing to formally express my extreme dissatisfaction with the randomly vanishing dashboard, all sorts of warning lights and its recurring issues. I see a recall for 2017 CRV for Fuel injector. I don't see my VIN for fuel injector recalls and most likely my CRV issue with fuel injector. Fuel injector replacement is a major repair. I. I scheduled an appointment with AutoNation Honda Chandler,AZ,to troubleshoot an issue. I believe these issues may stem from a design or manufacturing flaw. I am requesting that Honda cover the full cost of the necessary repairs.

Driving down an in town road going approximately 35 mph with no cars within 5 car lengths front side and back when I hear three beeps and my car brakes hard on its own and then continues. It was scary and I pulled off the road to a parking lot to turn the car off and on. While today I didn’t have anyone tailgating me, this could have easily been a bad accident in town traffic. I plan to contact my dealer tomorrow to report and have safetysystem checked and adjusted. I see that others have experiences like this and online was advised to report this.

Back in July, my car started having the lights come on; it lit up the whole dashboard. The brake system, tire pressure, brake hold system, hill start, adaptive cruise control, etc. It affected the power of the vehicle. There was no acceleration at all. It was like it went in limp mode. This has happened numerous times. The other problem is starting it was making a hesitation to start. It would also start rough as in almost like a shake. We noticed that it was using antifreeze more often than it should and would get hot sitting still. That's when we took car to be inspected by a certified mechanic and that's when we found out that we needed a new engine due to antifreeze seeping into the engine.

while driving on a clear day, i went under a bridge on a downhill slope and the car flashed the brake warning and applied the breaks automatically almost causing the car behind me to hit me. Dealer has not been able to reproduce the issue. this has happened a few times. once on the highway and another time slowly going through a construction site where there was a dip in the road. the last issue happened on 9/27/2025. the first issue was in March of 2024

On 9/2/25 all the engine lights came on on the dash. I replaced the battery and it was fine the rest of the day. Then 9/3/25 once again all the lights are on and none of the ADAS work.

Occasionally, for no reason, automatically brakes and issues the brake warning notification despite no traffic in front of the vehicle. When a vehicle brakes for no reason in traffic, the risk is that you will be hit from behind.

My cruise control will not work. Lane departure is not working. All my lights are on in my new vehicle I just purchased. BAD FUEL INJECTORS seem to be the problem. Honda should recall these bad fuel injectors before a serious accident occurs.

My vehicle braked hard on its own as I approached a metal pot hole cover in the street. It also flashes a BRAKE warning when I cross over shadows, such as from an overpass.

It has not been looked at yet due to not having funds to get it looked at. I do know others have the same consistent issue with these models especially when they’d get around 70,000 miles. All of the warning lights the last few months would continue to cut on and off. Now they just stay on. The Car drives fine though but is a safety hazard since it can’t tell us if something is wrong.

Date of Incident: [XXX] Location: NYC, [XXX]. Mileage: 95,000 Description of Incident: On [XXX] while driving my 2017 Honda CR-V at approximately [XXX] at 20 mph I experienced a sudden brake system failure. When I pressed the brake pedal fully to stop the vehicle, the pedal felt extremely hard and resistant, and the vehicle continued moving, failing to slow or stop as expected and hitting the vehicle in front. While no major accident happened due to how slow I was going, This occurred as I was approaching a traffic light. I did not apply the electronic parking brake (EPB) during the incident. No warning lights were illuminated on the dashboard at the time of the failure. Immediately after the incident, the brakes began functioning normally again, suggesting an intermittent issue. I am concerned about the reliability of the brake system, especially given reports of brake issues in 2017–2019 CR-Vs. I...

While I’m driving the car suddenly breakes.

Driving 25 mph on a straight road, the automatic braking system engaged with beep sound only but not on the dash display as it should. the car was suddenly braked to a stop. nothing was near or in front of the car.

On startup all safety warning lights flashed on and disabled all safety driving aids. This persisted and took to Honda dealer. Their diagnostics revealed faulty fuel injectors with code P0304 failed number 4 cylinder. Recommend replacing fuel injector go for $2000.

The AEB system is falsely being triggered, causing a sudden stop or drastic slow down of my CRV when there's nothing present to trigger the system. My car would drastically slow down, nearly causing a rear end collision from another vehicle. I've experience the problem on multiple occasions, in different locations, while going different speeds. The car has not experienced any other electronic or mechanical issue. The warning message did show on the dash as the car came to a halt.

While driving down a main road, with no other vehicles or obstacles around/in front of me, the Collision Mitigation Braking System (CMBS) beeped/flashed and my car came to almost a dead stop in the middle of the road. This happened without warning, or any previous warning/issues. Luckily no accident happened, as I don't believe a vehicle was behind me (but this could've gone horribly wrong had there been). It was a very windy day. I took it to a Honda dealership the same week, they found no issues and also could not reproduce this. I called Honda Customer Service, who was apologetic, but really no help, and only filed a complaint for me. I see this as being a high potential safety hazard for accidents, etc., and it makes me nervous now driving my vehicle, especially since this is something I cannot turn off. I wanted to file a report...

Fuel injector malfunction in 2017 Honda CRV EX. Getting all the warning lights. Mostly it shows Emission system problems.

We have had this problem more than once but this morning it nearly caused an accident. My husband was driving to work and all of a sudden the car's automatic breaking system caused the car to stop dead, causing the car behind him to have to swerve up on the sidewalk to avoid hitting him. He was not going over a metal plate, there waDSs no car stopped in front of him. This has happened at least ten times in the time we have owned the car and we have been INCREDIBLY lucky that it has not caused an accident, but it's still clearly a problem. We have complained about this to the dealership when we bring it in but they just shrug since they can't reproduce it and it seems to happen randomly. Just all of a sudden driving along BRAKE will flash on the dashboard and the car...

Multiple times when driving the vehicle will slam on the brakes without warning when there is nothing in front of the vehicle. I have taken it to Honda multiple times and they cannot fix it due to being unable to recreate the spontaneous issue. Also, they did try to recalibrate the sensor, and it still did not work. I don't feel safe driving this car and can't sell it knowing it is dangerous.

The CMBS system malfunctions and phantom brakes when there isn’t anything obstructing the road. It has done it 5 or 6 times, and the dealership can’t do anything to fix it.

In 2 separate incidents, the vehicle has applied the brakes on its own, with no obstacle in sight ahead of it. One time the braking brought the vehicle to a complete stop, the other time it started hard braking, then the braking stopped. Both times were in daylight with no animals or any other object ahead of the vehicle. One of the incidents nearly caused a collision with a vehicle following from the rear that would not have been expecting the sudden stop.

I was driving about 25 miles per hour, there were no cars in front of me (in either direction). The car suddenly slammed on the brakes for no reason. My passenger and I were both thrown towards the steering wheel and dashboard, things came flying from the back seat to the front, falling down by the pedals. I was very nearly rear ended, the car behind me was able to swerve to the left but was extremely angry. The car went into neutral, but possibly because something came from the back seat and hit the gearshift, I'm not sure about that. I was stuck in neutral with traffic horns blaring at me. If I'd have been pulling out into traffic when this happened I would easily have been hit broadside. I brought my car to the dealer, they said there was nothing wrong and that perhaps I didn't understand how...

I was driving on a major highway at 60mph when all of a sudden the car started to automatically brake intermittently with warnings flashing. I slowed down to below 30mph in the right lane and put my flashers on traveling to the next off ramp, while the car continued to brake intermittently and not respond appropriately to applying the gas. Several warnings flashed, including: Emergency Braking system problems; Crash Mitigation Problem; Transmission System Problem; Adaptive Cruise Control Problem. I was lucky to get to a safe spot without being rear-ended. I am having the car towed to a dealer tomorrow.

I was driving my dogs to their grooming appt and they were sitting in the front passenger seat around 10am. I was driving a little under the speed limit of 40. There were no cars in front of me but there was behind and to the left of me driving. I was not approaching a stop sign or stop light, just driving down the boulevard, when out of the blue the emergency automatic breaking system applied the brakes very hard. I had my seat belt on, but my dogs flew to the floor of the front passenger seat. I was so concerned about my dogs I didn’t even look to see if someone almost rear ended me, but there was NOT a collision luckily. I pulled into a parking lot and checked on my dogs. Obviously our safety was at risk because the brakes applied themselves right out on the...

Several times the braking system has engaged thinking there was something in the path of the car when there was not. My daughter & I were almost rear ended. It has happened on numerous occasions. Has not been taken in for service for this issue. There was no warning prior to each occurance

Traveling on open road, Collision Mitigation Braking System errantly engaged putting vehicle in a hard, emergency stop condition. Nothing in front of us but empty road. Both driver and passenger were thrown forward. Driver sustained neck whiplash injury. The problem will be reported to dealer on Monday. This is a very know issue with this vehicle. The internet is full of complaints and you have already received hundreds of complaints. Add mine to the list. Please address this.

Emergency braking system activated twice in a period of about 5 minutes without any objects/ cars in pathway. Speed approx 40 mph in bright daylight it has never done that before and I deactivated it until I can have mechanic check it out.

I was driving about 25mph past a school and the car automatically braked for no reason. Nothing was in the road, no cars near me. I’ve driven that road hundreds of times in the past 4 years without incident.

The collision mitigation braking system malfunctioned. The car would be available for inspection upon request. After the light turned green I entered the intersection, going approx 20mph, when suddenly the car braked on its own without a car/object in front of my vehicle. I could hear the beeping from the collision mitigation system at the same time. Since I did not know the car was about to stop, I was unable to prevent my dog from falling forward and striking the dashboard. Although myself, my dog and the people behind me were at risk, no injuries were sustained. The person behind me was able to stop luckily. I will be scheduling yet another diagnostic with Honda, though I just did that a few months ago when all the warning lights came on. After the injectors were replaced at that time, they were able to turn off the warning lights. I...

Every signal sensor in my car went off after 100k miles. Brake hold system, power steering, hill start assist, adaptive cruise control, collision mitigation, road departure, electric parking brake, tpm, emission system problem, all wheel drive system. Car stopped working and came to a complete stop on highway with my child in it which was not only terrifying but put us obviously in a life threatening situation. Brought it to Honda dealership-they cleared codes and said they could figure out what was wrong because their software was down. Made an appointment with Honda in a different city to check my rear brake actuator sensor as I had had my brakes replaced prior to these codes showing up. Had to have the car towed to the dealership as it would not drive at this point. The dealership put a VT sylenoid in and said it was good to go. I asked...

On 6 separate occasions (2 in 2018, 4 in July 2024) my automatic braking system has kicked in when there is no apparent obstruction, vehicle, etc. in front of me. I have not taken the car to the dealer or filed any inspection as no accident occurred and I saw an article online about this happening to the same model and year car and thought I should add my examples to the list.

My 2017 Honda CRV has been diagnosed as needing replacement of its fuel injectors. When this problem is detected by its onboard computer system, all warning lights illuminate on dashboard display (even though they are unrelated), and all the ADAS safety features are disabled until the system can be reset - these include blind spot detection, forward collision warning, lane departure warning, etc. Because the car was otherwise driving fine, I explored other possible reasons for what seemed to be an issue with the electronics, such as a faulty battery. Eventually, it became apparent there was a fuel injection problem when the car went into what others have referred to as 'limp mode,' which means that it struggles to accelerate to even 5-10 mph at best. Thankfully, the two times this happened before I was able to take it to the dealership were both on residential streets without traffic. If...

About 5 PM yesterday, August 2, 2024, the emergency braking system activated and brought my CR-V to a complete and sudden stop. The braking warning lite for a brief moment prior to the braking. There was no time for me to brake myself nor did I apply the brake petal. There were no vehicles, bicycles, or pedestrians on the road in front of me. Following the stop, the brakes released and we were able to continue forward normally. My and my wife's safety was put at risk first, if we had had another vehicle to our rear, and to the risk of neck sprain due to the sudden stop. I have not notified my Honda dealer as of today, Aug 3, 2024.. The vehicle has not been inspected by anyone as of today Aug 3, 2024.

On July 19, 2024, I was driving around 30-35 miles an hour. There were no cars close to me either in front or the back or side. My car started to abruptly slow down in a jerking fashion and then the car beeped. It scared me. It didn't stop completely and then the car started moving normally. If a car was behind me, I could have been hit in the rear. The message "brake" did not come on which is supposed to be the first stage in the forward collision safety. This never happened before and now I feel like I have to turn off the safety feature. My 2017 CR-V has 23,000 mi.

On June 30, 2024 and again July 13, 2024, the BRAKE dash light and sound alarm engaged on clear sunny days (~ 11 am (6/30) and 1pm (7/13). The brake did not engage and so I was able to maintain control of the car, but in both cases I was on a major highway at 50-60 mph. I have previously reported an incident about a year ago (NHSTA issue number: 11530134 reported 7/3/2023). Weather conditions were the same (sunny and dry) and about the same time of the day (midday), however I was on a regular city road traveling about 25-30 mph and the BRAKES light, sound and the physical brakes brought the car to such a hard stop that I moved forward fast enough to engage the seatbelt restraint mechanism.

My car’s automatic emergency braking system engaged at about 35 mph without cause. It was a very hard, abrupt almost full stop. I will report to my Honda dealer on Monday when they open. The car behind me was able to stop but was very angry. Thankfully he was not tailgating or we would have had an accident The car has done this before but not as severely and didn’t brake as hard, more of a slow down.

All warning lights are active on the dash touch screen and the IP. The warning is audible and visual and cycling rapidly and very annoying. Dangerous when driving as a distraction making driving after dark very dangerous. This is the second time in a year this same problem has happened. We are the original owners of the car bought from Art Mohen Honda in Jackson Michigan in 2017. The first incident was intermittent and the touch screen would clear. unrelated to the computer problem we we in a collision and during the repair process the car was taken to Art Mohen Honda and faults were cleared on the computer. This lasted 7 months and now the computer is in complete fault as described above.

Again this happened, driving at 38 mph the braking system activated without warning and slammed us into the seat belts. This is happening way to often and now my wife refuses to drive the car.

While driving at about 35 miles per hour, with no traffic or obstructions ahead of me, the automatic braking system rapidly decreased my vehicle speed to about 5 miles per hour, then disengaged and the vehicle operated normally.

I was driving my Honda CRV on a 4 lane highway (2 lanes in each direction) on a clear and sunny day ([XXX]) at approximately 45-50 mph. I had no traffic ahead of me, but cars behind me, when my vehicle slammed on its brakes and dropped my speed to approximately 5 mph. I did hear the beep and saw the "brake" warning statement on my dash display. It released the brakes after the decrease in speed (to approximately 5 mph) and I continued to drive home without any further problems. I'm very fortunate that I didn't get rear ended. I phoned my Honda service adviser and made her aware of the problem (West Herr Honda of Lockport, NY). My vehicle is in excellent condition and has never been in any accidents. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving in a 4 lane road up a slight grade my CRV abruptly stopped using automatic emergency braking in front of a metal plate laying in the road the was covering up some construction. I started driving again and the car again stopped abruptly several feet later at another metal plate.

3 times this has happened now the latest incident today 4-19-2024. I’m driving along and then all of a sudden the car goes into hard braking mode and the emergency braking light comes on the dashboard. Twice I have almost been rear ended because of this problem. No cars are in front of me at the time. I feel the automatic braking system was not designed correctly. I hope no one gets into an accident because of this defect. This is the last Honda I will ever own.

My 2017 Honda CR-V decided to brake all by itself while driving on the highway going 65 mph. This incident first happened to me in May 2023 on a clear sunny day with my 1 month old baby and fiancé in the car. My fiancé thought I slammed on the brakes but in fact I did not, I was on the highway going 65mph. I was so scared because I didn’t even know my car was capable of braking on its own until that day. Everything in the vehicle flew to the front of the car, luckily no one was behind me or in front of me at that time and we were all okay but we were shaken up. The second time it happened, I was with my fiancé again on a backroad about a month later with no one in front of me or behind me, again on...

There have been a few instances in which the emergency breaking system activated based on false positives. Examples include certain overhead highway signs (one in particular is a regular trigger in a certain lane of a certain road in my area) as well as dips in the road or construction areas or the bottom of hills, in which the sensor presumably reads the upcoming hill as an actual instruction. In one of these instances a car behind me locked up the brakes to avoid hitting me as my car applied the brakes unnecessarily. These issues have occurred repeatedly and are often able to be reproduced.
