Honda CR-V adaptive cruise problems

Filed Nov 9, 2026 · Driver assistance, Fuel system · NC

Vehicle: 2019 Honda CR-V (1.5L Turbo) Failure Mileage: 72,742 miles While driving, the vehicle experienced a sudden and catastrophic failure of the fuel delivery system. The primary engine malfunction illuminated the Check Engine Light, which immediately triggered a secondary safety system shutdown. The vehicle automatically disabled critical factory safety features, including the Collision Mitigation Braking System (CMBS), Road Departure Mitigation, Adaptive Cruise Control, and Lane Keeping Assist. The entire dashboard lit up with warning indicators, creating a significant distraction while operating the vehicle at highway speeds. A certified technician retrieved diagnostic trouble code P0172 (Fuel System Bank 1 Too Rich), confirming a fuel injector defect where raw fuel was leaking into the cylinders. The sudden, unprompted disabling of critical advanced crash-avoidance and emergency braking systems while in motion creates an immediate hazard to the driver, passengers, and surrounding traffic. Honda has refused to cover or remedy this known component failure outside of the baseline warranty period.

I had an incident recently that makes me think that there is a real issue with the collision avoidance system recognizing "unusual" objects. I was driving at night on a 75 mph dual lane highway. I had cruise control with collision avoidance engaged. A large truck had pulled onto the highway in front of me and was slow to accelerate. I assumed that my cruise control would immediately slow my vehicle down but it didn't! By the time I realized that it wasn't going to do that, I was a lot closer to the truck than I wanted to be. The truck was a "high off the ground" kind of rig and I wonder if the collision avoidance was literally looking under it. I agree that the driver is ultimately responsible for his vehicle but IMO it is scary if a warning system doesn't do its job. The official 2025 Honda CR-V owner's manual, in the section titled Adaptive Cruise Control (ACC) with Low Speed Follow, lists several situations in which the system may fail to detect a vehicle correctly. Two of those limitations are especially relevant to my experience: - A vehicle ahead has an unusual shape. - The minimum ground clearance of a vehicle ahead is extremely high. Honda also warns that detection can be compromised when the speed difference between my vehicle and the vehicle ahead is very large. We were able to avoid colliding with the vehicle in front of us, but only because we noticed that we were rapidly closing on the vehicle in front of us.

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.

[XXX] 12:38 AM (0 minutes ago) to me 2017 Honda CR-V EX-L AWD, approximately 111,000 miles. While driving, my vehicle suddenly displayed multiple warnings and repeated beeping, including Hill Start Assist, Adaptive Cruise Control, and Collision Mitigation System problems. The vehicle appeared to slow down and the brakes seemed to grab or engage unexpectedly, creating a risk of losing control or causing a collision with surrounding traffic. Startup stuttering has also occurred. The failed component is UNKNOWN. Possible causes include a malfunction in the ABS/VSA brake-control system, electronic parking brake, sensors, wiring, or electrical controls. A fuel-delivery or engine issue may explain the startup stuttering. The vehicle is available for inspection upon request. The problem has not been confirmed or reproduced by a dealer or repair facility to my knowledge. An auto-parts store tested the battery, starter, and alternator, which reportedly passed. Honda advised that my VIN is not covered by a fuel-pump recall. A manufacturer inspection specifically addressing the braking issue is UNKNOWN. No police or insurance inspection is known to have occurred. The warning messages appeared suddenly during the driving incident. The exact date was XXX going a speed of 60 and dropped down to 20 due to automatic braking, and road conditions were good, not wet or bumpy. The root cause according to Honda seems to be a fuel pump failure. I am reporting this incident because unexpected braking and multiple safety-system warnings may indicate a serious malfunction that could endanger me, my passengers, and other road users.

My car will stop when at red lights or stop signs. It’s like it dies. It also flashed 6 different problems at me: 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.

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.

I have experienced this 2 times once in late august early September of this year 2026 and on [XXX] I was making a left turn onto a street in Long Beach, CA in-between [XXX]. I was going under 25 miles and did not have cruise control or the driver assist for lane steering on and as soon as I started to make a left the vehicle abruptly stopped causing the upper half of my body to jerk forward hurting my lower back again and now I have slight headaches waking up in the morning again since then. Its like the vehicle sensed there was a vehicle in front of me, parked cars on the street or passing by me going in the opposite direction, and the automatic break came on as if I was going to be in a collision which I wasn't. Again, I didn't use the steering assistance in the vehicle, because I stopped using it after the first incident occurred. The second time, [XXX] I was going to slow for cruise control to be on, so I'm not sure why this mechanism even was active unless it's just a built-in feature. Nevertheless, built-in or not, it malfunctioned injuring me. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2026 Honda CR-V has a major design vulnerability. I purchased this vehicle on 8/22/2026. On 10/1/2026 my vehicle was vandalized in the parking lot where I work. In a matter of seconds, without any special tools, a thief pried the front logo off the vehicle and stole the radar sensor/module which directly disables Honda sensing safety systems (including collision mitigation braking and adaptive cruise control) which causes cascading dashboard error lights (generating systematic driver distractions). The front logo lacks mechanical lockouts allowing thieves to leverage it off with a simple flathead screwdriver in under 30 seconds. After paying $38,000 for the vehicle, I now have to pay to replace the sensor/module. I received a quote from the local dealership for $1,892.66 (parts/labor), and there are no assurances that it won't be vandalized again. I filed a police report and a claim with my car insurance company. I also filed a complaint with American Honda Motor Co., Inc. Honda needs to initiate a design recall so this issue can be rectified. The sooner the better.

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. More if anyone is interested, out of characters. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA)
