Collision mitigation system does not work; initial issue was warning systems went on with no one in front of car. Second time brakes were applied to vehicle with no one in front of car, leading to car induced panic stop on road, thankfully, no one was trailing my car at that time. Honda test drove and could not find anything; since this is sporadic, this was not surprising. Told them it is a very dangerous condition and that this is a well documented complaint on websites; they told us we can turn off front mitigation collision system each time we drive. Requested dealership general manager to report this condition to regional director at Honda
Honda's collision mitigation system shuts down, disallowing cruise control and all safety features that are included in the collision mitigation system. Dealer cannot find cause. Turning off the car and restarting it resets it, but when it turns off, there is no clear factor as to why it happened. There is a safety risk if you are using cruise control, as it could fail to brake when the car in front of you slows down. It has happened 4 or 5 times in the past 8 months since I bought it brand new.
Adaptive cruise control (acc) fails during use, the vehicle can automatically accelerate to a set speed and slow down when it senses a vehicle within a close proximity. When the acc is active and after a few times of needing to automatically slow down when another vehicle is in front of the vehicle, the system shuts down and an error message appears, " collision mitigation braking system problem. See your dealer". I've taken the vehicle to the dealer and there was no fix to the problem, my vehicle is still currently under warranty and I was disappointed that there was no fix to this problem. The date listed below was the most recent date that the same incident occurred, I took the vehicle in to South motors Honda dealer back in 2018 shortly after purchasing the vehicle.
Multiple errors involving vehicle's collision mitigation braking system (cmbs). Cmbs system fails regularly (approximately every 120 miles of driving) during routine use at freeway speeds. System failure shuts down adaptive cruise control (acc), collision mitigation braking system (cmbs) and displays error to "see your dealer".
Collision mitigation braking system activated for no reason, on surface roads and highway speeds, vehicle slammed on brakes automatically, there is nothing on the road in front of the car. This has occurred numerous times. Dealerships told me that there was no registration in the warranty system because they were unable to fix the problem so no record of this problem was sent to Honda usa.

Collision mitigation, lane assist, road departure, and brake system malfunction before vehicle is a year old causing vehicle to leave roadway when using speeds in excess of 50 mph preventing vehicle from stopping, and/or causing steering wheel to "alert" you of lane departure while driving properly also causing vehicle to "steer" into side of 18 wheeler while traveling speeds in excess of 60mph for interstate travel with passengers in tow. Has happened for roughly 7,000 miles. When brought to Honda to be fixed, was told it was not covered under vehicle warranty due to having "clips" broken off of front sensor. Was accused of sensor being hit by something yet no sign of damage. Honda refused to have this fixed and simply "cleared" the alerts causing vehicle to not have use of any safety features but also not show any maintenance codes as well. Honda service manager stated something as simple as a "junebug" can cause this to malfunction and that is why customers carry collision with insurance. States alot about Honda's quality if a simple junebug can cause an entire $30,000 vehicles safety features to malfunction and a service manager not want to comply with safety standards due to some 2$ broken clips that can break by simply driving down a Louisiana roadway. What does this state about these vehicles up North dealing with snow with a sensor that sits underneath the front bumper?
The collision mitigation system and adaptive cruse control (acc) has on two occasions turned off at highway speed - potentially dangerous situation if you are depending on the system to regulate your speed in traffic. The car must be stopped and restarted to reactivate the system. Also, the system at times applies braking when there are no other cars or other obstacles in it's line of sight. This also seems to happen (not always) when overtaking a tractor trailer at highway speed. I have researched this problem on the internet and other Honda owners have experienced the same issue, typically with the dealer not being able to find a problem. Apparently the error codes reset when the car is restarted.
I have a 2018 Honda Accord 2.0T touring. I have numerous incidents where the collision mitigation braking system has gone out giving an amber dash warning to see the dealer. This has happened 6 times all when the adaptive cruise control was engaged. It also disabled the cruse control. All 6 times I was driving on the interstate. The road was flat and straight and it was a clear sunny day with no other car in the vicinity.the radar unit and camera were free of bugs. Most times, upon shutting off the car and restarting everything returns to normal. However, one time upon restarting the car the phone, radio navigation, adaptive cruse control, cruse control and collision mitigation braking system would not come back and I had to take the car to the dealer. This car was taken to Honda of el cajon, ca on 4/21/18 and chapman Honda, AZ on 7/31/18 and 7/3/19. No problem was found all 3 times
Active cruise control (acc) failed while driving approx. 40 mph. Approaching the vehicle ahead of me which was rapidly slowing/stopping, the acc failed to slow my vehicle which forced me to manually apply hard braking at the last moment to avoid a collision. When I looked down there was an error message on my instrument cluster which read "collision mitigation braking system problem. See your dealer". the weather at the time was clear and 62 deg. F, and the vehicle was clean with no dirt nor obstructions on the front radar unit nor the windshield (camera area). The acc could not be restarted until I pulled the car over and shut it down/restarted it, which then cleared the error message and enabled me to reinitiate the acc system. This is a significant safety defect!
On 2018 Honda Accord the adaptive cruise control which is standards on all trim levels, does not brake the vehicle to maintain the set speed when going downhill. This is odd since the vehicle will apply brakes to maintain speed if there's a vehicle in front of the car, but on downhills all it will do is make several downshifts to try and maintain the speed. Every other car I've driven that has adaptive cruise control will apply brakes to keep the vehicle speed from increasing in an uncontrolled manner. Of course if you tap the brakes yourself cruise control is disabled. A simple software update would resolve this issue.
The contact owns a 2018 Honda Accord. The contact stated that the vehicle went into limp mode and the engine warning indicator randomly illuminated. The vehicle experienced a loss of power more than twice while making a turn and driving highway speeds. The contact had to coast the vehicle over to the side of the road, and shut off and restart the vehicle. Waikem Honda (3910 Lincoln way E, massillon, oh 44646, (330) 477-5002) was unable to duplicate the failure or locate a diagnostic trouble code. The dealer and manufacturer technician test drove the vehicle, but found no failure. The vehicle was not repaired. The manufacturer was notified. The approximate failure mileage was 4,000 and a second time around 7,300 miles. Consumer stated when the goes into "limp mode" and I cannot accelerate. If I were in the left lane passing a semi, I could visualize this a fatal accident. I am anticipating another "limp mode" soon as I have just over 11,000 miles and it seems to happen about every 3 to 4,000 miles.
The collision mitigation braking system warning light comes on intermittently. I have to stop the car turn it off and turn it back on in order to reset the warning light. The dealer tells me this is a known problem but they don't have a fix the light has come on in all types of driving conditions, clear and dry, rain, etc.
I engaged acc, that controls cruise control and frontal collision, mitigation system, in normal traffic. While travelling at a speed of 60 miles per hour, following another car the spacing was controlled by acc. The car in front of me continued forward, my braking system engaged and caused me to go from 60 mph to about 35 mph. The vehicle to my rear had to take an evasive maneuver to avoid an accident. I saw no road debris. I pulled over to check the radar unit and the camera system. No issues observed. During this trip the acc went offline 3 times down to SC and twice it failed driving back home. Each time I was in traffic and caused issues as the system was trying to manage my speed in traffic.
I have had several occurrences of a warning that states "collision mitigation braking system problem. Please see your dealer." This error message will pop up randomly with no pattern while using the advanced cruise control function on my vehicle. While this error is present I am not able to use any kind of cruise control settings. I was have seen my local Honda dealer about this issue multiple times and have been given many horrible solutions. I have been told to just pull the vehicle over and restart it to clear the errors out. I have also been told by my local dealership that the camera is just dirty and that I need to carry a bottle of water and a rag to wipe off the windshield anytime it happens. I have tried both of these solutions several times and neither has worked. In fact every time I attempt to turn off and restart my vehicle I have eight other safety system failure messages that populate.
Since the vehicle reached approximately 5000 miles, I had a massive safety failure of the "Honda sense" system shutting down, hazard & turn signals inoperative, power locks inoperative, brake system warning light on, loss of auto headlights and information screen. Vehicle was taken to the dealrship and they retrieved trouble code which is a "mystery code" that Honda does not know why its occuring.... radar told car to accelerate when vehicle was not in motion U0401-92 along with 3 other codes. Dealership showed me printout from computer but customer receipt said reset system only and did not list out trouble codes (4 codes retrieved) vehicle now stops intermittently while driving at highway speeds, pulls itself out of the lane while driving, and apple car play system no longer will recognize iphones (tried multiple) and dealer has verified issue but just resets. Infotainment screen lost power and set warning message for same when dropped off again at dealership 2/26/19. Dealer in Florida also had car, said nothing wrong, could not duplicate and vehicle never left dealership and carplay did not work after they claimed it was fine. Also found that entire system was reset and rebooted, causing loss of all settings and stored information/stations....why reboot if its working? vehicle now being driven with Honda sense system off due to fear of collision or accident caused by vehicle and not driver. This vehicle is now unsafe to drive. Multiple complaints about vehicle braking on its own, flashing "brake" warning to driver when no car in front... happens local and highway driving now intermittently. Vehicle has been in dealerships approximately 4-5 times since inital electrical failure 12/24/19. Email contact and several phone calls to hma already. Original electrical failure happened 12/23/28 and I have been dealing with since. Also have snapshots
Cmbs problem... was driving on the highway yesterday when the "collision mitigation breaking system" light came on and that disabled the acc I was using. Nothing particular happened, maybe I was braking at the time. I arrived at destination. Turn the car off and back again right away to see the warning light disappear and everything back to normal. I thought I was ok but it happened few hours later on the way back in the same circumstances.
Car is 2 weeks old and I've had the cmbs which controls the autobraking and adaptive cruise control go off 4 times with the failure warning and to see the dealer for inspection. Each time was under a different set of environments including at night, a cloudy day, rain, and sunny. It seems to fail within 10 mins of the first time the adaptive cruise is set. The green light that indicates the system is working goes off and turns to orange. I've contacted the dealer for repair but online searching shows both dealers and Honda do not have a fix.
On 2/14/19, I was driving on a city street in a straight line at approximately 40mph. The car ahead of me stopped. I stepped on the brake and instantly the dashboard warnings lit up - adaptive cruise control, collision mitigation braking system, road departure mitigation system, and the brake - and the brake did not work so I could not stop. I rear-ended the car in front of me doing significant damage to the front of my car. The warnings were still visible after the crash and I took pictures of the dashboard as best as possible. The warnings say something about system not working and to see a dealer. The same warnings appeared on 2/13/19 in the afternoon but disappeared on 2/14/19 in the morning. Other warnings of safety systems not active have appeared due to ice/slush but then cleared when the sensors were cleared, but these new warnings are different. At least twice, maybe three times in the past few months, the car would suddenly brake and slow down with nothing in the road or in front of the car. My bluetooth connectivity worked fine for first 2-3 months but then stopped and I couldn't reconnect the phone over the past two months. It seems like more than one system/electronics problem and seems like the warnings appeared at the same time as the brake not working as if it was more than an alert but a system (systems) no longer functioning at all. The brake worked after the accident when the car was restarted.
My collision mitigation system randomly fails which pops up an alert and disables my adaptive cruise control and automatic braking. It has happened various times when adaptive cruise control has been engaged with different environemental situatuons (day and night, sunny and cloudy). Turning off the engine and restarting typically corrects the issue for a time but it continues to fail intermently.
Vehicle running, both driving and stationary, dash indicated three warnings: "adaptive cruise control system problem", "collision mitigation braking problem", "road departure mitigation problem". all three systems were nonfunctional. Dealer advised to drive through a car wash before coming in for repair. The car wash appears to have worked, but this is absurd! every time it rains or car is dirty, the safety features don't work? didn't see this disclosure when I bought the car or when I paid for these features.
