Problems with 2018 Honda Accord VEHICLE SPEED CONTROL

Car on a straight road, no adverse weather conditions. the collision mitigation braking systems shuts down. this has occurred during both day and night time and has happened six times. the radar panel was not obstructed. the cmbs can only be reset by stopping and restarting the car. i have contacted the manufacturer's customer support with no resolution. i have contacted at least two dealer service centers with this problem, no resolution. they say they need to see the error code - problem is, the warning resets when the car is restarted. this problem has been reported by other customers on the car complaints website. most recent occurrence was on 06 feb 2020. the cmbs has shut down at different mileages, both in and out of the cars warranty.

The collision mitigation braking system and adaptive cruise control system has thrown an error and stopped working 5 times now. it has happened to me on long road trips on the highway at speeds of 50+ mph. it has happened less than 30 minutes after starting the vehicle and sometimes after 2+ hours of driving. the weather conditions have ranged from cloudy to fine (no snow or rain). this is extremely dangerous to have happen at highway speeds in traffic.

While driving on highway at 65 mph with cruise control on brakes suddenly applied themself nearly causing a vehicle to strike me in the rear .several alarms were displayed on dash first was adaptive cruise control second collision mitigation braking system third departure mitigation system problem all alarms said to see your dealer . i took pictures with my cell phone of all alarms displayed but i'm having difficulty uploading to report . i can send a attachment specific to the claim if needed or if a email could be given i would forward such.

Under certain driving conditions when the car is slowing down while using acc (cruise control) the system will fail causing the brakes to disengage.ever time this happens 3 times so far i was driving at the posted speed limit. most time the speed limit was 55 mph. traffic went from posted limit to an almost complete stop.the car would start to slow down then the system would fail, allowing the car to continue forward almost causing a collision. the message "collision mitigation braking system problem see your dealer" is displayed. honda has a tsb 19-051 that talks about the issue. when i took the car to dealership about issue they refused to do the tsb.

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

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, 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 ...

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.

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 accords 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.

Tl* the contact owns a 2018 honda accord. the contact stated that the brake pedal was extremely difficult to depress because of the placement of the accelerator pedal. the situation impacted the contact's driving ability. honda city (3859 hempstead turnpike, levittown, ny 11756, (516) 717-4762) was contacted and unable to provide a remedy. the vehicle was not repaired. the manufacturer was notified. the vin was not available. the approximate failure mileage was 0. *js *js *js *js *js

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.

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.
