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

The car continuously has issues with all alerts appearing on the dashboard. This deactivates safety features like lane departure assist, front collision mitigation, and cruise control. This is a known problem with this generation of crv and the problem has become worse since Honda starting sending letters to customers about resetting their radar sensor.

I purchased a brand-new 2026 Honda Cr-v hybrid. Less than three months later, the adaptive cruise control and collision-avoidance radar module was stolen in under a minute, forcing me to pay $2,650. 98 out of pocket for repairs. In new york, the front radar module on the new Honda Cr-v hybrid is a frequent target for theft; owners often suffer losses of around $3,000 in just sixty seconds (exact costs vary by Honda service center). I consider this a clear design flaw by Honda: the collision-avoidance radar—which also integrates the adaptive cruise control function—can be easily removed using only a screwdriver, without even opening the hood or doors. This situation is completely unacceptable. Honda has failed to implement any anti-theft measures to prevent such incidents, leaving owners facing massive financial losses in the blink of an eye. This is unacceptable. Honda service personnel have acknowledged that the front radar on the new Cr-v is extremely susceptible to theft. They have already repaired multiple 2026 Honda Cr-vs that had their front radars stolen. I strongly suspect that the Honda Cr-v suffers from a serious design flaw. I strongly demand that Honda provide compensation to owners whose radars have been stolen.

My car will stop when at red lights or stop signs. It’s like it dies. It also flashed 6 different problems at emissions system problem, awd system problem, adaptive cruise control problem, collision mitigation system problem, road departure mitigation system problem, auto high beam problem. This is so frustrating considering I just got this car, and there’s no recall, but I believe it’s the fuel pump. Please recall this. I can’t put so much money into this car.

Driving from [xxx] to [xxx]. On adaptive cruise control with lane departure active. In [xxx], on the interstate, with the interstate curving to the left. Left curve illustrated on dash in cluster. Approaching a vehicle in the right lane while on cruise, it was going slower than my set speed. This vehicle was slowing for an exit on a ramp that was straight away aligned with the right lane, curve starting just after this ramp. This vehicle was braking for the ramp. Our vehicle chimed alerting to the approaching slower vehicle. We were whatever Honda specifies for a correct following distance, at least 8 car lengths if not further. Our vehicle rapidly slowed even though this forward vehicle was on the exit ramp. Then it rapidly decelerated to around 40 mph from the 70 we had been at. We had no vehicle in front of us in the interstate through lane. If we had had a vehicle following us at the normal "too close distance" we could have easily been tail ended. There was zero reason for the vehicle to brake for the exiting vehicle. The adaptive cruise apparently was fixated on the forward vehicle, and did not incorporate the lane keeping data that showed the road turning. This rapid braking surprised us, and I had to override the vehicle stepping on the accelerator to regain speed. I have no idea how slow it would have gone. The lane change software also consistently have problems with decel lane marking, pulling the vehicle to the right when these happen pushing us out of lane position. It also registers black tar coating on straight seams as lane markers, either moving the vehicle or shaking the wheel to alert us of an issue - - which does not exist. There also does not appear to be an effective interface between the "hands on steering wheel" sensor and existing road conditions that consistently result in shakes or alerts for events fully under the drivers control.

The car randomly braked hard and suddenly. There were no obstacles in the road. It was a clear day with no weather issues.

I took my Honda in to a dealership for a trade-in value assessment. The dealership used automatic start with my key fob. Once they got in, they began to drive it in immediately it would not go past 10 mph, began jerking, and steering became an issue. It begin throwing the following check engine light codes: tire pressure monitor problem. Electric parking brake problem. Road departure mitigation system problem. Collision mitigation system problem. Adaptive cruise control problem. Hill start assist problem. Vehicle stability, assist problem. Power steering system problem. Brake hold system problem. Brake system problem. Emissions system problem. Trade-in became impossible and it was not safe to even drive off the lot. It remains sitting in the car dealerships parking lot, leaving me without a vehicle.

On August 20, 2026 at approximately 3:45 pm the vehicle slammed on it's brakes unexpectedly with the acc active. The acc was set to 45mph as per the speed limit and was traveling at that speed until the brakes suddenly engaged and abruptly reduced the speed to 20mph. It was sunny, 91 degrees there were no cars, obstructions or shadows and the vehicle had been washed and clean 2 days before.

Vehicle may experience driveability issues, which may result in dtcs p0300 (random misfire detected), p0301 (no. 1 cylinder misfire detected), p0302 (no. 2 cylinder misfire detected), p0303 (no. 3 cylinder misfire detected), p0304 (no. 4 cylinder misfire detected), or p0172 (fuel system too rich) or a whirling noise coming from the engine compartment. Possible cause based on certain driving patterns and environmental factors, the dtc's stated above may be set or a whirling noise may occur. Apparently only certain VIN numbers were affected, mine is not in the list but im still having the exact same issues.

Driving on I-69 with all adaptive systems on including cruise control set at 65 miles per hour. The car had slowed to about 60 due to ahead car. . It started raining rather hard, a message said the Honda emblem was dirty and it automatically disabled all adaptive systems leaving the car moving at about 60 miles per hour without warning. I fortunately manually braked to avoid a rear collision. This disabling procedure happens to fast to be safe in traffic or at higher speeds.

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.

Stolen radar sensor on Honda Cr-v. Thief able to unscrew without causing any damage. Resulted in multiple sensor warnings (brake system, cruise assist, lane departure, power steering, etc. ).

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.

All of the adas lights, check engine, and brake lights come on every 2-3 weeks. Has been taken to the shop multiple times now. So far have had the battery changed, spark plugs changed, and fuel injectors.

The safety driver assist options work periodically . . . All the dash lights are on when breaking system is not working properly. While driving with cruise control on the brake system/driver assist options will fail and car will automatically start slowing down. Not very safe!! the front camera seems to be causing the issue.

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.
