I was accelerating from a stop at a red light and once I hit about 10-15 mph, the collision mitigation system came on and slammed the car to a complete stop for no apparent reason. I have a dash camera video which shows the incident. This was on a clear, sunny day on a non-busy city street (overpass).

The vehicle had a sudden loss of function in: 1. road departure mitigation 2. collision mitigation 3. adaptive cruise control 4. braking system the vehicle was in motion at speed of 10-40mph, with air temperature of 28-32 degrees and snowy conditions. Honda has repeatedly refused to investigate numerous, potentially sw/hw - related issues that have been manifesting themselves in other parts of the vehicle. What happened today was a new set of symptoms, but with much higher severity and no obvious precedent. I have already had to disable the lane departure and the collision avoidance systems on this vehicle due to their erratic behavior. However, in this case the messages that have come up (will attache photos) demanded that the vehicle be taken to the dealer and the errors and message did not go away upon multiple restarts of the vehicle. Upon arrival to the dealer, it was indicated to me that Honda is aware of some of the other issues I've been experiencing with the vehicle and still (months hence) does not have a fix, and that Honda has, essentially, been resorting to testing their vehicle on the customers, instead of more rigorous pre-release testing, instead choosing to use the dealers as a quasi-test/R&D department. The multiple safety system failure I experienced today is a pretty clear indication of that. I have filed another complaint with nthsa related to the other issues and would urge you to initiate a recall on all of the Honda Accord (and possibly Odyssey and Pilot as they share some of the sub-systems) for the 2018, 2019 and the coming 2020 models.

Collision mitigation system failed, brake light is on, adaptive cruise control system warning is

- Blaine, MN, USA

Rear brake pads are wearing quicker than the front, I barley have any life in the rear pads. (wearing out twice as fast as they normally should) just like what happened to the 2008-2010 Accord. Honda looked at the issue and completely ignored it, they told me its dangerous if I dont change them and they didnt say anything about them wearing out quick.

The brake system alert is flashing on the dashboard while vehicle in motion and there is no break issue. It appears to be a flawed collision mitigation brake system sensor as this keeps flashing across the dash in big bold letters and wont go off. I just bought this vehicle brand new 5 months ago. When turning car off and back on the message is still there and wont go away.

My car (3 times now) while driving on a highway will suddenly brake hard with no cars in front of it almost causing a rear end collision with my car. An orange light comes on the dashboard saying (brake) in large letters. I am getting scared to drive the car now.

When traveling at high speeds the brakes keep setting themselves. We were almost rear ended during one instance. The Honda dealer has not been able to fix this very dangerous situation.

I went to the dealership for and oil change at 20,000 miles and was told that my rear pads were worn and needed to be replaced. The front pads are fine. This issue was recalled in 2010 and needs to be recalled again.

Collision mitigation braking system warning indicator is visible on the dash after vehicle shudders and jerks, and adaptive cruise control becomes disabled until the car restarts. This happens while vehicle is in motion at highway speeds, above 50mph.

- Lake In The Hills, IL, USA

Brake pulsates are when applying brakes at speed 40 moh or higher. Since I noticed and took it to the dealer after 12.5K miles they will not cover the repair. According to the associate this will continue to happen every 12K miles.

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

My 2018 Honda Accord sport crash mitigation system is not working correctly at highway speed with no vehicles around the brakes apply hard at times taking the car from 65 miles an hour down to 40 mph in just a few seconds on one occasion I almost got rear ended by a tractor trailer Honda says there's nothing they can do about

My 2018 Honda Accord braked spontaneously for no reason. The word brake appears on the console and the car engages the brakes suddenly and forcefully. I've had several incidents and there were no vehicles or objects in front of my vehicle. During two episodes, I was driving 40 mph when my car braked spontaneously- it caused my head/neck to jerk forward. Fortunately, the vehicles behind me did not tear end me. I called the dealership. They said the brake mitigation system engages when driving through construction zones and told me to turn off the system in construction zones. He said 'that's how the system is designed to work'. I was not in a construction zone. This is extremely dangerous. It appears Honda is aware of the problem and is not taking steps to correct it.

- Glendale, AZ, USA

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".

When driving with cruise control and forward collision avoidance system enabled the car will at random times apply the breaks when there is nothing in front of the vehicle. So far this has happened during interstate driving approximately 2-4 times in the first 10,000 miles of ownership.

- Ferdinand, IN, 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.

Today I was driving home, doing 45 miles per hour. This is a two lane road, there were no cars near me. Suddenly, the car beeped twice, the brake sign came on the dashboard and the car stopped violently. The seat beat locked down across me. Thankfully there was no one behind me. My neck and right shoulder are now hurting. The incident happened a mile from my home. My husband called the Honda dealer when I got home to report the incident. This is the third incident since we purchased the vehicle, but this time was a more violent stop. Each time there was nothing in front or beside the car. Thankfully, each time no other car was directly behind me.
