The problems with vehicle started three months after purchasing it in November 2018. I have four documented cases with the dealership. As well as 7 videos of the incident taken place while the car is in motion. The tachometer and entire dashboard, including entertainment center, shuts off while driving. This is a big safety issue especially while using the gps. The system reboots itself while the car is in motion. Honda corporate is aware of the issue and had not provided a fix for the issue to date, despite representations that such fixes would be available by fall of last year. I also have voicemail from the service and parts director of the dealership admitting fault and no fixes for the problem. I have additional evidence I can share. For "when did this happen?", I have put the approximate last time this issue arose. The problem is ongoing and has been since I bought the car in November 2018. Please note that my pdf files cannot go below 6mb, so I need to submit that to you some other way when you contact me. Thank you for your time.

Accord accelerates to surge at random - it happened 4 times. Two times when we were driving on the freeway, one time on the street, and one time was when we were stopped at a red light! we had to brake very, very hard, and use our emergency brake! we are lucky that no one was in the cross-walk when this occurred. As you see in the attached receipt, the problem is the tape used when our Accord was built. The dealer said that this is happening once per month at their location where cars are brought in with the same problem. The dealer told me that the wires are faulty because rodents are attracted to chew on the cars wires specifically. When we called Honda customer service about this issue. The customer service representative said that Honda is aware of this issue, and has made rat tape to address it, but that Honda is waiting to hit a certain number numbers of complaints so that it is enough to meet its threshold before issuing a full recall.

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.

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.

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.

On Sunday night (11/10/19) around 5:15 pm, I was driving down the left lane of a 2-lane highway at ~55 mph. The closest vehicle was no less than 5 car lengths ahead of me. Randomly, the orange "brake" light came on in the dash and the car automatically slammed on the brakes almost to a complete stop causing my head to jolt forward. Luckily the car behind me was able to stop as I started to accelerate again. I believe there was nothing in front of me or on the road that should have caused this safety feature to engage. This was very dangerous and scary. I woke up this morning in excruciating pain from my neck and shoulders down to my lower back. The pain has been getting worse throughout the day and is now radiating down my arms and I have limited range of motion. Last night, I figured out how to turn off the automatic brake feature and have not turned it back on today.

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.

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".

- Collierville, TN, USA

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.
