Adaptive Cruise Control Problems of Honda CR-V - part 1

I have a 2017 Honda crv which has intermittent bucking type issues, if I accelerate during that time the check engine light will turn on and the car will stop, sometimes when I turn the car on it will shake a bit like it struggled to turn on, in these cases most warning lights will turn on but the car will drive. Battery has been checked and it giving good output, what else could it be. Every warning ligh turns on and the car does not let me go faster than 25mph. This happens 2x on a highway and this time while home in my drive way.

Since approximately mid-2024, my 2017 Honda Cr-v has intermittently displayed a cascading series of dashboard warning lights, including tpms, abs, vsa (vehicle stability assist), eps (electric power steering), brake system, hill start assist, adaptive cruise control, collision mitigation braking system, and road departure mitigation. When active, these lights fully disable Honda sensing driver-assist features. The pattern is consistent and recurring: warning lights remain active for approximately 3-4 days, then self-clear for 1-2 days, before recurring again. This cycle has repeated for over 18 months. A windshield replacement with camera recalibration temporarily resolved the issue for approximately one week before it returned. On 07/02/2026, I brought the vehicle to an authorized Honda dealership (Honda of short pump, richmond, va) specifically to diagnose this warning light cascade, and paid a $195 diagnostic fee. The technician's documented complaint states the lights are intermittent and 'stay on about 3-4 days. ' despite this being the stated complaint, the dealership's diagnostic report identified only two unrelated fault codes — p05a0 (active grille shutter malfunction) and p0172 (fuel system too rich) — and did not identify, report, or provide any code specific to the tpms, abs, vsa, eps, or adas/camera systems actually affected. When asked, the service advisor verbally attributed the light cascade to the shutter and injector faults, but could not provide supporting diagnostic data. This explanation does not align with the reported timeline, as the tpms/warning light cascade began approximately one year before the shutter fault (p05a0) reportedly occurred as a single, non-recurring event. I am concerned that a genuine intermittent fault affecting multiple safety-critical systems (abs, vsa, eps, braking, and collision avoidance) simultaneously has gone undiagnosed for over 18 months, and that this may represent a broader pattern affecting other 2017-2018 Cr-v.

I am writing to formally request that Honda investigate and acknowledge a significant security and safety concern regarding the front radar module used on certain Honda vehicles equipped with Honda sensing. The front radar module appears to be easily accessible from the front of the vehicle and can reportedly be removed by a thief in a matter of seconds without requiring specialized tools. Because of its location and lack of adequate theft protection, it has become an attractive target for theft. The theft of this component is more than a financial inconvenience. Once the radar module is removed, critical driver-assistance and safety features—including adaptive cruise control (acc), the collision mitigation braking system (cmbs), forward collision warning, and other Honda sensing functions—may become unavailable until the sensor is replaced and professionally calibrated. This can leave owners without important safety technologies they relied upon when purchasing the vehicle. I respectfully ask Honda to investigate this issue, acknowledge the vulnerability, and consider implementing a remedy for affected vehicles. Possible solutions could include an improved anti-theft mounting system, a redesigned sensor location, or other security enhancements that make unauthorized removal significantly more difficult. As Honda owners, we should be able to feel confident leaving our vehicles parked without worrying that a critical safety component can be stolen in seconds. Beyond the financial burden of replacing the radar module, the loss of these safety features can affect the safe operation of the vehicle and diminish driver confidence. I urge Honda to take this concern seriously, communicate with affected owners, and evaluate whether a service campaign or safety recall is appropriate. At a minimum, I hope Honda will acknowledge the issue and work toward a solution that improves the security of the front radar module and restores owners' confidence in the safety of their vehicl.

1. Sometimes when my wife get in the passenger seat the airbag sensor light stays on indicating the the airbag is off. 2. Often when driving with adaptive cruise control on, the car suddenly brakes hard without cause . Sometime when a car in front of me turns right and sometimes if I pass a car parked on the street it will also brake hard for no reason.

There is a known recall for my vehicle and Honda has been negligent in attempting to fix the recall.

The vehicle’s forward collision avoidance and adaptive cruise control radar sensor is mounted directly behind a plastic front emblem that can be removed in seconds without tools. This design allows easy theft of the radar unit, which immediately disables Honda sensing safety systems including collision mitigation braking, adaptive cruise control, forward collision warning, and lane keeping assistance. Theft of this component renders federally marketed safety systems inoperable and results in dashboard warnings and loss of active safety features. Replacement and required recalibration costs are extremely high, commonly reported between $1,500 and $2,500. This issue is caused by exposed placement and lack of theft deterrence for a critical safety component, not by vehicle misuse or modification. Similar thefts are being reported by other owners, indicating a widespread design vulnerability that allows essential safety systems to be disabled through simple theft.

Driving using cruise control on interstate. Car in front of me exited. My car began to slow even though there was nothing in front of me but a slight incline. I pressed on the accelerator and the car continued to slow. I turned off the a/c and cruise, but the car continued to slow and came to a complete stop on the interstate. There was a semi-truck behind me. Cars were passing me. I put the car in park and turned off the car. I started the car back up and drove away. I was completely stopped on an interstate with construction barriers on each side of the lanes, so there was no shoulder to pull off on. I was fearful of getting in an accident or causing one. I was very scared for my safety. There were no warning lamps or messages to assist in the moment. I took my car into the dealership and explained what happened. Dealership checked the cruise control and said "test drove vehicle and cruise control operation is normal. " they reset cruise control follow distance from closest to farthest and could not duplicate the concern. I am no longer using the cruise control because I feel it is a safety issue that was not addressed.

The front radar sensor behind the emblem on the grill is very easily stolen due to a design flaw. It was stolen, replaced, and stolen a second time. This is happening so much that Honda can’t keep up with replacement parts, leading to service delays, which cause many people, including my pregnant wife and now new baby, to drive for weeks without critical safety features. This is unacceptable and Honda needs to issue a recall and provide a fix to the design flaw.

When driving vehicle with cruise control on and getting close to or in an intersection the vehicle will slam on brakes without driver apply them. It's happened a few times so far and the vehicle is only about 3 months old. Once while driving down va beach boulevard and starting into an intersection when there was a lot of traffic so was worried a vehicle could have slammed into the back of us. And other times this would happen just before entering an intersection or while approaching an intersection.

After the low-pressure fuel pump recall repair was performed on my 2018 Honda Cr-v at doggett Honda med center on March 6, 2026, the vehicle began experiencing a serious and repeated loss-of-power condition. The vehicle suddenly loses power without warning. This happens with no clear pattern, at highway speeds and also at low speeds. The engine does not shut off, but the vehicle loses the ability to accelerate normally. In some situations, it does not have enough power to safely reach the shoulder, leaving me exposed in traffic. This has now happened multiple times and has become more frequent. I have already narrowly avoided at least three serious rear-end collisions while trying to move the vehicle out of traffic. Yesterday, the vehicle lost power again and a police unit had to escort me so I could safely move the vehicle to the side. When I turn the vehicle off and restart it, it temporarily returns to normal, but the problem keeps coming back. This makes the vehicle unsafe and unreliable for normal use. The vehicle is my work vehicle, and I depend on it for transportation. I am now unable to work normally or travel safely because I do not know when the vehicle will suddenly lose power again. This condition places my life and the lives of my passengers at risk. I contacted both the dealership and american Honda corporate. However, my safety concern has been minimized, and I was told that I would have to pay for diagnosis, even though this problem began after Honda performed recall work on the fuel system. I am reporting this because this is a serious safety issue. A vehicle that suddenly loses power in traffic, without warning, creates a real risk of collision, injury, or death. Honda should properly investigate whether the recall repair, fuel pump system, connectors, wiring, or related fuel delivery components caused or contributed to this dangerous condition.

In November 2025 a new transmission was installed curry Honda in atlanta GA on my 2020 Honda Cr-v. The new transmission came with a 3 year/36,000 mile warranty. In March 2026 my vehicle broke down and was towed to tameron Honda in daphne al where a speed sensor was replaced at my expense of 388. 44. The adaptive cruise control was not working prior to this repair. Within two weeks the vehicle experienced further issues and had to be driven in a compromised condition back to curry Honda in atlanta where the transmission wire harness was diagnosed as corroded and replaced at a cost of 1696. 99. My vehicle has been garage-kept its entire life except when in the care of a dealership. Corrosion on a recently replaced transmission in a garage-kept vehicle cannot be attributed to environmental exposure or owner neglect. It points directly to a defective part of improper installation at curry Honda. These failures occurred within months of a new transmission installation with no prior history of issues. I believe this is a safety defect as the vehicle broke down unexpectedly and had to be driven in a compromised condition posing a safety risk.

I began experiencing "sticky" steering at highway speeds, requiring that I use force to keep the vehicle from drifting out of its lane. The problem worsened until, roughly one month later, the cruise control system went out without warning and refused to come back on. I took the car to the Honda dealership in port charlotte, FL on 3/30/26 where they were able to duplicate the problem immediately and recommended I no longer drive the vehicle until the steering rack/gear box is replaced. Honda steering is sensitive. Overcorrecting is a very real danger in addition to the possibility that it may lock up at high speeds in traffic. No warning lights ever indicated a problem. I am aware that other 2018 crv's were recalled for this issue to have the racks replaced. My VIN was not included in that recall, but clearly, my vehicle is having the same issue. I spoke with corporate Honda on 3/30/26.

For 7 days straight, during cold weather, the car dashboard would cycle through at least 7 indicators indicators reporting such as lane departure, tire pressure abs, cruise control failure, emission system failures, posing a danger when showing up in the middle of trips on the highway. In other instances, the warnings start as soon as the engine starts, or within 1-2 minutes of starting the engine. The factory remote start feature does not work when the dashboard warnings cycle through, as well.

Engine light came on loss of power. I had to have it towed back home. A independent shop investigated the situation found coolant in the cylinder head. They found out it was a bad head gasket, which led to engine failure when going to replace the head gasket part of the cylinder wall peace was missing. I had to replace the whole engine.

The vehicle began experiencing repeated engine misfires, hesitation, and loss of power during normal driving. The issue was diagnosed as failing fuel injectors, which is a known issue on this generation of Honda Cr-v. The failure causes sudden hesitation and reduced engine power, particularly during acceleration and at intersections, creating a safety hazard in traffic. In some instances there was a strong fuel odor, raising concern for a potential fuel leak and fire risk. The injectors failed well before normal service life and required replacement. Honda has not issued a recall for many affected vehicles despite widespread reports of similar failures across multiple model years. This defect presents a safety risk due to possible engine stalling, loss of power, and potential fuel leakage.

Issues with 1. 5l turbo engine and fuel injector causing safety features to be disabled and flash on dashboard repeatedly, also heard of many issues with head gasket failure in this specific engine which could lead to driving in limp mode on a highway(20miles or less). These safety concerns could potentially be life threatening if these issues occur on a highway.

While driving in arizona on I 10 at normal speeds, the sunroof glass exploded. No overpasses. No ice. No big trucks close by. The interior cover was closed at the time. Mileage at the time was 6600 approximately. Car was purchased new last summer in utah. Could not figure out what happened at first until we stopped the car at an exit. Glass was bulged up with the middle missing.

The automatic braking system is activating automatically without any warning or any interference even though there is no vehicle or object in front it is happening all of a sudden and it a serious safety hazard and could cause major accident it is life threatening and I am very scared to drive it a life and death situation please look into this matter and have Honda fix this issue before it causes and deaths.

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.

The failure involves the electric brake booster (ebb) / brake control system on my 2020 Honda Cr-v hybrid. The malfunction affected brake assist, abs, vehicle stability assist system problem, brake hold system problem, brake system problem,electric parking brake problem, road departure mitigation system problem,collision mitigation system problem, adaptive cruise control problem, hill start assist problem. The vehicle and components are available for inspection upon request. This failure created a serious safety risk. Braking performance became inconsistent and unpredictable, increasing stopping distance and reducing vehicle control. This condition increased the risk of a crash during normal driving or emergency braking. The problem is persistent and reproducible. Multiple brake-related warning lights reappear every time the vehicle is driven. The symptoms are consistent with electric brake booster failure reported on similar vehicles. Dealer diagnosis is pending / has identified a brake system fault related to the brake booster. The vehicle has not been inspected by Honda corporate. It has been / will be inspected by an authorized dealer or qualified service center. No police or insurance inspection occurred because no crash happened. Warning lamps appeared suddenly while driving, including brake system, abs, and vsa warnings. There were no prior symptoms such as noise, vibration, or gradual brake degradation before the failure. Once illuminated, the warnings remained active.

Every dashboard light came on. Engine, brake and all the adaptive controls were flashing. The whole dash was lit up and my cruise control and lane assist wouldn’t work. Among other things I’m sure. I want to know if this is going to happen again and what about the head gasket now? can you do the update/ thermostat on my vehicle since obviously it is defective? the car only has 65,000 miles on it. I always heard Hondas were the best vehicles. This is now very concerning. Please advise.

Driving with no other cars in sight the crv randomly slammed the brakes on and showed break in the info center. This happened twice last night.

On July 18 I was stopped in the red light behind a car in the new york city suddenly my car moved I applied the brake hard but almost hit the car in front. The message in the dashboard were -depress brake pedal apply parking brake,brake system problem brake performance may be reduced,brake hold system problem apply brake when stopped,vechile stability assist system problem reduce traction and handling,hill decent control system problem apply brake when descending,adaptive cruise control system problem,collision mitigation braking system problem,low speed braking control problem. I turned off the car and start again and it worked. This was the first time I was able to take the pictures it happened before as well but I was unable to take picture. After that I took the car to hillside Honda service center I showed them the message of the dashboard which was on my phone. The car was in the service center for two days they said that my car was fine at that time the message of the dashboard was only in my phone. On month of Sep and oct I took the car again to the hillside Honda service center with same issue and after staying two days in the service center they said my car was fine. After that I press braking hold and continued my work. On Nov 6 and Nov 8 same problem occurred I was able to take pictures. Beginning of Nov I was driving at the highway suddenly the message pops up I was sure that the brake wouldn’t work, push the emergency lights,changed the lane and I was lucky that there was a empty space on the corner of the highway. I applied the brake but the car stopped almost 10- 15 meters ahead. I turned off the car there was no customer after 5 minutes when I start the car everything was fine. On Nov 23 I was driving at the highway with a customer same message pops up in the dashboard press the emergency light,changed the lane and again found a empty space at the side of the highway. This time also I was able to take the picture.

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.

Loss of power and control of vehicle after getting several malfunction errors on instrument panel. Vehicle estates that several safety controls are switched off until problem is resolved. Eventually vehicle resets itself and works fine for weeks.

I own a new 2025 Honda Cr-v purchased from Honda of concord (hendrick automotive group, concord, nc). At around 220 miles, the vehicle’s dashboard displayed major safety warnings: “collision mitigation braking system problem” and “adaptive cruise control system problem. ” soon after, a very strong burning smell—similar to fire or overheated brakes—came from the vehicle. When I brought it to Honda of concord, the service advisor (ashley petisce) initially refused to accept or log my safety complaint. She only agreed to inspect the car after I stated that I would hold Honda and the dealership responsible if an accident occurred. Later that day, she also told me the burning smell was normal and would “go away after driving more,” which was alarming given the severity of the odor. After finally inspecting the car, the dealership found that both front rotors, pads, and calipers were defective and required replacement on this brand-new vehicle. When I requested that all related safety sensors (acc, cmbs, radar, and cameras) be checked after the brake repair, the same advisor said she would “only check what policy allows,” meaning only the brakes, and no further sensor or system testing would be done. This raises serious safety concerns. The initial refusal to inspect could have resulted in brake failure or fire. The defective brake components indicate a potential manufacturing defect, and the disabled safety systems create an immediate crash-risk condition. The dealership’s refusal to confirm sensor functionality after the repair leaves the vehicle’s safety systems unverified. I request that NHTSA investigate whether other 2025 Honda Cr-v vehicles have similar brake or sensor defects and whether Honda’s dealer network is properly following safety-reporting procedures.

I had adaptive cruise turned on and set to 36 mph, a vehicle which was a good distance in front of of me turned left across the oncoming lane and into a parking lot. Even though the car that made the turn was already in the parking lot the car slammed on the brakes. I have the entire incident in video. Of course this problem also exists and is even more dangerous at high speeds. I have complained to Honda USA three times and NHTSA once a few months ago and no response. My daughter who has the same vehicle also experiences these issues. Someone is going to get seriously injured . I’ve had cars behind me almost cause a wreck on the highway because of the slamming on brakes issue . Please advise where I can send the rascal video. It’s a matter of life and death.

While the adaptive cruise control is on for no reason the car breaks giving risk of being hit from behind. While driving down the road the brake light just comes on to say brake brake and there is no one in front or on the side of us. This has happened multiple times and I have owned the car for 4 years.

I am reporting a severe safety defect involving the engine and fuel injector system that began two months ago at ?108k miles (now 109k miles). I have not yet taken the vehicle in for service due to the estimated high repair cost of $2,900. It is critical to note that the same underlying problem was subject to a safety recall for the 2017-2018 model years, but the defect was not fixed for my 2019 model year. This indicates a persistent manufacturing or design flaw that warrants an immediate investigation into my model year. The defect manifests regularly, causing a cylinder 2 misfire (p0302) and making the engine run very rough with a sudden and severe loss of power. This creates a direct rear-end crash risk due to the inability to maintain a safe operating speed. More dangerously, when the misfire occurs, the vehicle instantly disables critical driver assistance systems—adaptive cruise control (acc) and lane keep assist (lkas)—without any advanced warning. This malfunction is an unreasonable safety risk: crash hazard: the unprompted power loss and concurrent disabling of safety features create an immediate, dangerous situation. Fire hazard: the persistent misfire strongly suggests a failed or stuck-open fuel injector, which causes fuel dilution of the engine oil. This contamination can lead to engine failure or, critically, a fuel leak onto hot engine components that poses an extreme fire risk. I urge NHTSA to investigate why this defect persists and to mandate a comprehensive recall to protect the public from this ongoing, life-threatening safety risk. The failed component may be available for inspection upon request.

I just filled a report but on October 3rd @ 3:34pm the same thing happened where while in cruise control the car just brakes and there was no reason for that to happen.

My car's steering wheel started making a noise when turning at around 2,000 miles per hour, and the steering wheel became very heavy when turning. I took it to the Honda service center twice. The first time, they told me there was nothing wrong with the car. The second time, they fixed the noise, but the heavy steering problem remained. When I drive at around 25/35 mph in a 25-35 mph zone, the steering wheel becomes very heavy, and it becomes extremely heavy above 50 mph. The Honda service center can't solve the problem, but I'm very worried about the possibility of an accident.

After vehicle was shut down for about 5 to 10 minutes while in a store, all lights on the dashboard came on with warnings that most all safety related systems had "problems" (tire monitoring system, emissions system, brake system, brake hold, power steering , variable steering assist problem, hill start assist, adaptative cruise control, collision mitigation, road departure) vehicle would otherwise run fine and could be driven home. Emergency brake still seems to operate. This has happened twice in the last six months and renders the vehicle less safe to operate without these systems fully functional.

I have 2 issues with my car - the first one has been ongoing and I should have reported it sooner - when using cruise my car will sometimes brake for no reason, it's as if the car sees something that's not there. The second one just occurred and has only happened once. I was driving on the highway using cruise and I got a message on the dash that said something like cruise control disengaged - the cruise turned off and the gas pedal didn't work so I had to coast to the shoulder. Luckily, I didn't have to cross any lanes of traffic or it could have been extremely dangerous. I plan to contact the dealer as soon as I am done with this submission. I wanted to be able to tell them that I had notified the NHTSA.

While using adaptive cruise control at 47mph on a local highway, automatic emergency braking activated almost stopping the vehicle with vehicles fairly close behind it nearly causing an accident.   there were no vehicles beside our car and no vehicles or objects on the road in front that could trigger the braking.   this has also happened several times at lower speeds on less crowded roads.   after the last occurrence, I took the vehicle to the prescott Honda dealership where they were unable to duplicate the problem.   they documented the problem but told me that Honda would not replace the sensors under warranty unless the Honda technician was able to duplicate the problem while driving it.   if this happened on a busy interstate highway like I-40 or I-17 at 75mph with vehicles or a large truck close behind, it could cause a serious accident.
