Cruise Control Problems of Honda Accord - part 1

On three occaisions, the driver safety assist system shut off. Each time there were no obstruction in radar and the day was not a hot day. The auto assit cruise control shut down to. Shutting the car off seemed to reset. I was unaware by pressing the main swith on steering wheel will reset the system. But as I said turning off the vehilce seems to reset. I checked lane departure but it affected all safe driving systems. Your system would only allow me to check one box it would not let me check.

The contact owns a 2020 Honda Accord. The contact stated that while driving at an undisclosed speed, the cruise control function fails and the vehicle decelerates without braking. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 50,000.

I was driving approx 70 mph on the interstate hwy when I engaged the cruise control. Shortly after that the car began braking. Pressing the accelerator wouldn't disengage the cruise control. The car came to a complete stop in the middle lane of the interstate. Only after turning off the engine and restarting was I able to drive.

July 2020, adaptive cruise control (acc) system DE-active while I was driving at approx 65mph. Received dash board message �collision mitigation braking system problem. See your dealer� . Warning went away after restarting vehicle. Dealership could not replicate warning. Nov 2020 acc system again failed, three times, similar circumstances, highway 65-70 mph, restarting again cleared warning. When system fails the cruise control element turns of, and cannot be reactivated. Also, car slows down quickly, because set speed is not maintained. ( potential rear end collision situation) car was purchased new in Nov 2018, not problem detected until early July 2020. Problem has not been resolved as of Jan 2021.

I was following my wife's car on the expressway. Her speed was 55 mph. I had the adaptive cruise control (acc) on my vehicle set for 70 mph, so naturally I was only �pacing� her at her slower speed, about four car-lengths back. Suddenly, my car accelerated rapidly toward my wife's car in front of me. I had to hit the brakes to avoid a collision. At that moment, a warning appeared on the instrument panel stating that radar obstructed. But even then, I was able to recreate the same scenario four more times before turning off acc for the rest of the trip. I also noticed that while the car was surging forward, the instrument panel indicated that there was no car in front of me, even though there clearly was. It was almost as if my car �couldn't see� and decided to accelerate anyway. The system should have failed in a safe manner, but it clearly did not.

While driving on the highway, I had the cruise control activated at approximately 70mph. My vehicle has adaptive cruise control and on two separate occasions within one day, there was no one in front of me but the car started braking hard. Fortunately, no one was behind me or they probably would have rear-ended me as it took me a few seconds to cancel the cruise control since it caught me by surprise. In at least one of the instances, there was a large tractor-trailer to the right of me so I'm not sure if it perceived it's shadow as being a vehicle. I bought this vehicle new in 2013 and this was the first time that the adaptive cruise control caused the vehicle to brake when no one was actually in front of me.

Was driving down the road after getting coffee with active cruise control on and a message popped up saying " collision mitigation system fault" please visit dealer", I've read that it can get bug juice on it and cause it to say that but I wiped mine off and it is still saying that after I restarted the car, have read from many car groups that this happens alot with these cars.

While driving my car at 60 mph on cruise control, it suddenly started increasing speed. Then I noticed that the accelerator pedal was pressed to the floor of my car. Then I began to use the brakes to try and control the speed, but they did not function well at all. Finally after struggling in on this rural road, I was able to slow it down, I called 911, then I just used the emergency brake to stop it because I didn't know what else to do. Although this was a terrifying experience, it could have been tragic if had not been in a rural area with very little traffic. Up to that point, this car had been in excellent condition low maintenance and really good car, but that day it was smoking and I thought it would catch fire. Lastly, the repairs cost $696 which is much more than I had ever paid for this car.

"collision mitigation braking system problem. See your dealer. " warning has appeared seven times in the 4,300 miles I have owned the car. When the system errors the emergency braking does not function, the adaptive cruise control does not function, and even the traditional cruise control will not set. Turning car off and one does reset the issue but it keeps appearing at random times when I drive the car. I have taken the car to dealer multiple times they tell me they cannot do anything unless the warning light is on when they have the vehicle. This issue has been going on since I purchased the car brand new in November 2019.

~tl-the contact owns a 2020 Honda Accord sedan the contact stated that while driving at various speeds in cruise control, the steering wheel forces the vehicle to depart to the right allowing the contact to regain control of the steering wheel. The contact also mentioned that when an object or vehicle is near the contact vehicle the brakes engaged without warning as the accelerator pedal is depressed the vehicle resume back to normal. The vehicle was taken to the dealer mcgrath Honda 2020 n randall rd, elgin, IL 60123 where it was diagnosed and test drove however unable to duplicate the issues. The vehicle was taken back 5 additional times still was unable to duplicate any codes. The manufacturer was made aware of the failure and informed the contact to take the vehicle back to the dealer for more diagnosed test as no further assistance was taken. The failure mileage was approximately 3,200. Ck.

While driving a new 2019 Honda Accord sport with active cruise control (acc) and lane assist at night, the car has on three separate occasions over 10 months malfunctioned. Both the acc and lane assist stopped working. The dash said "collision mitigation braking system problem" and "road departure mitigation system problem". If the car is restarted the malfunction and warning messages clear. The dealer has looked at the car three times, but they have not been able to identify the problem.

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.

1st time: adaptive cruise control on, vehicle driving under 25mph in traffic. The system works fine under a time lapse of 1-2 minutes after that the system turns off automatically & warning indication pops up on dash. "collision mitigation braking system problem see your dealer" normal conditions on the road & traffic when the problem happens. The warning light resets after the car is turned off. Took the car to the dealer & nothing was found in the system. They recommended removing toll sticker from the windshield. I removed the sticker & leave the dealer to test the system. 2nd time: adaptive cruise control on, speed set to 60mph on highway. Normal conditions on the road & traffic. Same problem, the system works fine under a time lapse of 1-2 minutes after that the system turns off automatically & warning indication pops up on dash.

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.

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.

Leased this car brand new 2 weeks ago. Tire pressure monitoring system light has already came on twice. Check air pressure, it was where it should've been. Light went away after I reset the system. Upon driving on the highway using adaptive cruise control and lane keep assist, the �collision mitigation: braking system problem. See your dealer� message popped up. Honda sensing functions were all disabled as well as regular cruise control. This happened on a cloudy evening as the sun was setting. No rain or inclement weather. Message went away only after parking the car, turning it off and restarting it. Took the car to the dealership to have it inspected but the diagnostics test came back inconclusive as the computer was unable to detect any codes. Service guy said that it could've just been a plastic bag or flying object that hit the sensor of the car causing the message to pop up.

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".

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.

The collision mitigation braking system and cruise control randomly stop working. It requires a restart to activate these important safety features. The car was on the highway each time. It has happened three times in the last week. Attached is a picture of the warning of the failure.

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.

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.

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.

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.

Leased 2018 Honda Accord in October, 25 miles later had checked engine light on,took it back to the dealer,emission hose wasn't attached properly. After 900 miles the wheel alignment went out ( I did not hit any pot holes) took it back to the dealer, According to the dealer one the rod wasn't set right, now it's January 2019 and have 4000 miles yesterday the car started to supporter and all the warning started flashing auto high beam, adaptive cruise control, collision mitigation, road departure mitigation. . . . All this sing said see your dealer. . Guess what I called the dealer first thing this morning. . Today is January 24 2019 still waiting to hear from the dealer all this technology is totally useless. . . I had 2002 Honda Accord with 310,000 miles and no technology.

Collision mitigation braking system problem,car brakes by its self ,was driving at 75mph and car slamed on brakes to 35 on us 71 almost caused an accident. Also monitor on dash that has home ,nav,audio settings shuts off by its self and reboots. Braking problem happens on cruise control and normal driving. I photo the dash 5 times when collision mitigation went off in a 5000 mile period .

In the states where it snows, the car collects large amounts of snow on the front, and knocks out the radar system for the lane departure detection system, witch also is for the braking system, that helps with cruise control and any close encounters. I am not sure if it actually affects the cruise control because in the snow is not a time to use it.

The collision mitigation braking system has completely failed twice on my month old 2018 Honda Accord. When this fails, the cruise control is also deactivated. Both times the car was in motion with the adaptive cruise control active.

Adaptive cruise control(acc) stops working with error "collision mitigation braking system problem. See your dealer. "I was driving on interstate at 60mph with acc on and suddenly the error pops out. Error goes way when you restart the car. But repeats again intermittently. You cannot use acc again until you restart the car.

While driving with the cruise control on the collision mitigation and braking system will intermittently turn off and disable the cruise control. Dealer says nothing is wrong, claim the sensors are overloaded. This can happen on bright sunny days, cloudy days and at night. Sensor on front of car is clean; no bugs, smears or liquids. Will reset with a stop/start of the engine. Code check revealed. Uo401-53 temporary stop of integrated driver support system -- received stop request by pgm-fi system. Error code 401-93 temporary stop of integrated driver support system -- received stop request by pgm-fi system. This happens only when the cruise control is on and moving. This has happened at least 12 times in the past 8 months, most recent was today.

Two separate issues: 1) with only 2,400 miles on the Accord, on October 7, 2018 it suddenly lost power 2 or 3 times over a 60-mile stretch of the busy 405 freeway, each time slowing from 65 mph to approximately 30 mph or less despite maintaining even pressure on the accelerator. The car did not respond to pressure on the gas pedal. No cruise control was used at any time. The sudden deceleration could have caused a serious accident. 2) on November 30, 2018, I attempted to resume motion after stopping for a red light. The Accord's gas pedal failed to respond for approximately 5 to 6 seconds, then suddenly lurched forward. This also could have caused a serious accident.

While driving at highway speeds with acc (adaptive cruise control) enabled and lkas (lane keep assist) enabled and passing a car and another time an 18 wheel truck, the car suddenly and abruptly braked to slow down 5 mph. The road was straight and no cars were in front of me. This was a very dangerous situation because cars were behind me and they all had to react to slow down. T.
