2017 Honda CR-V: false forward collision warnings

Filed Oct 14, 2026 · Brakes, Driver assistance · NJ

[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.

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.

While driving my 2017 Honda CR-V in stop-and-go highway traffic during wet conditions at 7:40 am on 9/24/26, suddenly multiple warning lights appeared with audible chimes and I suddenly was unable to depress the brake pedal normally. When I attempted to apply the brake, it felt like it was solid and had no effect on the speed of the vehicle. I immediately activated my hazard lights, crossed 3 lanes of traffic to reach the shoulder, shifted into neutral and had to coast to a stop on the shoulder. Steering felt stiffer than normal as well. I didn’t even have time to absorb all the warnings that were occurring. After safely stopped, I saw that the vehicle displayed the following warnings, cycling through them (I have a 1:25 video of this): * • Lane Keeping Assist Problem * • Collision Mitigation Problem * • Road Departure Problem * • Blind Spot Information Problem * • Brake System Problem * • Electric Parking Brake Problem * • Tire Pressure Monitoring System Problem * • Transmission System Problem * • Brake System Problem * • Brake Hold System Problem * • Power Steering Problem * • Vehicle Stability Assist Problem * • Hill Start Assist Problem * • Adaptive Cruise Control Problem I placed the vehicle in park and then it was towed to a repair facility and then to a Honda dealer and is awaiting evaluation. I thankfully was only traveling between 25-35 mph at the time due to traffic, and there was enough buffer between me and other cars that there was no accident. However, at normal highway speeds, in the metro area I was in with little shoulder and high traffic, an accident would have been an almost certain outcome with severe injuries or death as a result. I had no issues with the vehicle prior to this and just did regularly scheduled preventative maintenance on 8/21/26 (oil change, tire rotation, transmission fluid replacement).

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 experienced an dangerous incident yesterday while driving my 2017 Honda CRV at highway speed in Minneapolis, MN area. The Collision Mitigation Braking System activated suddenly and without warning. An extremely abrupt/harsh employment of the braking system was experienced without any warning. The unexpected and extremely sudden activation of the braking system caused myself and the car’s contents to be thrown forward into the front of the vehicle, and causing me to nearly loose control of the vehicle. It felt like this 'safety' system took control of the vehicle for an eternity, but likely was no more than a few seconds before power returned to the accelerator and I was safely able to navigate to the far right lane. The onset and braking was so abrupt and extreme, that I could have been easily rear-ended if someone was directly behind me. There was nothing immediately in front of me that should have caused this system to activate. I had no idea at the time as to what was going on, thinking my car was having some sort of mechanical issues. I drove home on ‘pins and needles’ hoping I would make it to Baxter, Mn where I live. I later learned that this was likely the CMBS, as other consumers had described exactly what I experienced. Even though I now intend to disable the system, I am now extremely apprehensive to drive the vehicle for fear this will activate unexpectedly again, causing an abrupt and dangerous (potentially life-threatening) while in traffic. This is a shame as I’ve really enjoyed the CRV, but now feel like it is a ‘deathtrap’ and have lost all confidence in driving it for fear of my safety. I brought this to the attention of the dealership in Burnsville, MN where the car was purchased (Walser). I was told they’d make a note of it, but that I needed to call HONDA directly with any reports. I informed them that I would be filing a report with NHSTB. I have not had the vehicle evaluated, but can make available for inspection if helpful.

My 2017 CRV Touring was working fine. I had a fender bender accident and they replaced the Collision Mitigation Braking System with a new Honda part. After the repair and I have the car in cruise control, it will suddenly brake and decelerate when there is nothing in front of me. This is very dangerous when you're going 65 mph on a highway. It is at the Honda Short Pump dealership. They have had it for 4 working days and can't find the problem. I know there was a class action lawsuit and Honda won, but surely this is a very serious problem they should fix.

I have experienced instances of the brakes being aggressively applied unexpectedly when no other vehicles or stationary objects are nearby to trigger the collision avoidance system. Any car following immediately behind would have rear-ended me. This has occurred a few times in the last 12 months. No warning lights are present prior to, or when this occurs. I have not had the vehicle inspected by anyone given the intermittent nature of this issue.

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.

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 here as well, in hopes that investigations are happening for this issue.

The dash warning lights all come on when the vehicle is started. Numerous Warning messages scroll across the dash indicating just about every system on the vehicle is malfunctioning. The collision warning system stops working, the lane change warning stops working, cruise control stops working. I have no idea what else could have stopped working that could mean the difference between life and death. My vehicle has had this problem for almost two years now. This problem stops after disconnecting the battery for 15 minutes then it comes back unpredictably. Honda dealerships just guess what the problem is because there are no definitive error codes. They randomly want to change parts like fuel injectors, onboard computer, brakes, battery, and others, and charge thousands of dollars and will not refund the money when the problem reappears. This problem is putting drivers at serious risk and Honda has done absolutely nothing to find and repair the problem. There are hundreds of reports of this problem online and Honda has not responded. Honda dealerships are making tons of money from this issue and doing nothing to solve the problem.
