Brakes engage randomly during normal driving. Brake system lights come on. Problem appears randomly and is difficult to reproduce. No service codes are stored so service technicians do not know how to repair the problem

On 11/22, when my car was in accessory mode, the stereo system was flickering and the warning sign saying that there is a problem with my brake system appeared on the dash board. I also noticed my break pedal was pulsating. I took it to Honda and they changed the battery of my car on 11/30. I called Honda customer service and they told me this is a known issue but they do not have a fix for it. Two days after I got my battery changers, the touch screen went out while I was driving and caused the stereo system to reboot. Today, I was at the stop light waiting for the light to turn green. There was not a car infront of me and when the light turned green I took my foot off the pedal and the car started to move. About two seconds of moving the car, the car breaked by itself and the hazards lights came on- this happened on 12/14. A car behind me had to swerve to avoid hitting me.

The contact drove a 2019 Honda Accord loaner vehicle. While driving very slowly, the "road departure mitigation failure", "brake system problem parking brake not available, brake performance may be reduced', 'brake hold system problem apply brake when stopped', and "see your dealer" warning messages appeared. The vehicle was towed to Honda of covington (100 holiday square blvd, covington, la), but the cause of the failure was not determined. The manufacturer was notified of the failure. The VIN was not available. The failure mileage was 645.

Received "collision mitigation braking system problem. See your dealer." Error messages no less than 5 times. The 2019 Accord touring has roughly 5K miles. I took it to the dealer the first time and restarted the car in the bay. The error light went away and they told me to come back if it happened again. The error message came back several more times over the next several weeks. I scheduled an appointment. I suggested faulty brake switch be looked at but was told the car just needed a "reboot" and to call if I had any further issues. The issue returned several days later. I believe in each case the adaptive cruise control was on and speeds were under 30. I believe the system was applying the brakes as we approached the car ahead in slow moving stop and go traffic. Only on one occasion was there rain or wet roadways. In all other instances the road and skies were clear each time on relatively straight road.

My 2019 Honda Accord, purchased new July 25, has 2365 miles on it. Twice very early in my ownership of the car the collision mitigation braking system (cmbs) activated with no cars in front of me. I forgot about the problem as it did not repeat itself until three incidents 9/11 and 9/12 2019. Cmbs activated yesterday evening (9/11/19). It happened again 9/12 my drive to Chicago on I-294. I called Honda of racine right after that happened and was told to bring the car in for service. He told me to turn the system off. It happened again on my drive home from Chicago. I searched the problem on-line and found numerous similar complaints on: Https://www.carcomplaints.com/Honda/Accord/2018/brakes/service_brakes.shtml many of the complainants who have brought their car into Honda dealers for service report having no satisfaction. What is also troubling is that the system did not work today when there was need for an emergency stop when the car in front of me braked and swerved left (in a narrow construction zone) to avoid hitting the car that had to stop suddenly in front of him when a tow truck started backing up on the road to service a car on the side of the road. I braked quickly and the car behind me swerved to avoid hitting me. The cmbs did not activate in this situation. 9/13: Waiting at Honda for diagnostics. I have been shown a May 2019 Honda service bulletin which acknowledges this issue. I see numerous NHTSA owner reports of identical problems.

When I brake from a speed of 30-40 mph, the pedal feel is not smooth throughout the braking motion. First, I start to brake but I do not slow down, only when I press even harder does the brake engage but at that point it is a heavy brake make the car lunge forward. Basically the brakes only engage when I press harder on the pedal but doing so makes the braking not smooth. This uncertainty when the brakes will engage makes for a dangerous situation when driving in stop and go traffic. I have to heavily concentrate on braking. My car is brand new with only 1450 miles on it. I took it to the dealer but they do not believe my story even when they test drive.

On a total of 6 occasions during the first 4500 miles of using my new car, the brake alert sign activated without reason for provocation, I.e., no other cars nearby, nothing in roadway. Four occurred while doing 65 mph on interstate. The last 2 occasions were startling as the brakes were triggered, causing the car to fishtail and swerve left momentarily as if attempting to awaken a driver falling asleep. On those occasions I was doing about 50-55 mph on a highway with other cars on the road but not close enough to need to brake. One time I was taking an exit to get on another highway. The other time I was going through a construction zone but there were no circumstances that would have caused the need to brake. I took the car to the Honda dealership immediately after second occurrence and left for 24+ hours. They acted as iff that couldn't have happened unless I were too close to something -- they'd never heard of the problem. They test drove for 13 miles, and the problem did not occur for them. Nothing problematic showed up on diagnostics. Nothing was done to correct the situation. I disabled the collision mitigation system after leaving the dealership.

Applying brakes gives a non-linear response that makes it difficult to brake smoothly and safely. Applying the brakes results in varying responses that appears not to brake and then suddenly grabs. I suspect that there is either air in the system or part failure of the brake booster or master cylinder. Dealer said that it is 'normal' brake response for this model of vehicle even though the salesman and service tech felt the problem upon driving. Also had collision brake mitigation problem light go off on my way home from dealer.

With only less than 800 miles on the car, my 2019 Honda Accord vsa modulator (which was diagnosed by the dealership) failed. I felt the car begin to bog on the highway right before we were on the exit. Then, the gas pedal stopped working properly and the car lost speed. I would press hard on the gas pedal and the car would take about 3 seconds before it started to move forward, jerking in the direction I intended it to go. After struggling a little while, I luckily pulled over and called a tow truck to send my car to the dealership. I felt that I was very lucky to be able to safely pull over. 1st, it happened during an early Sunday morning with heavy rain, so there was not much traffic. 2nd, the event occurred right before we were going to exit the highway with only a few hundreds of feet to go. Also, it's in my hometown and I know the road very well. Otherwise, an uncontrollable car could cause very serious accident. If we were to crash, the event would likely be attributed to driver fault - since it is such a new car - rather than a crucial car part failing, which could cause death to many others who buy new Honda Accord 2019S. Therefore, I believe that this issue should not be taken lightly and should be further investigated.

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.
