2019 Honda Civic Driver Assist & ADAS Problems

My vehicle has randomly had the emergency brake assist applied when there was nothing in front of me. Thankfully there were no vehicles behind me & the times that there were it was residential roads that are 25mph. If this continues to happen it could cause an accident, having my vehicle go from 45-55mph to a complete stop with zero warning & no ability to continue driving until the alert disappears from the dash is quite dangerous. I haven’t had my vehicle looked at yet as it’s not something I can easily replicate, but I’ve seen quite a few complaints about it happening so I figured I should report it as well.

I leased the Honda Civic from a dealer in Maryland and the first advertisement for this car was this car has lane departure warning and adaptive cruise etc. I report some incidents of inefficacy these systems in my car while it showed alarm and Honda maintenance team assured me that it works perfectly. i was driving on Fwy I-40 West in New Mexico. After wind blow my whole front shield became foggy and the system did not show any alarm that it is not working. I ended up deviated from the road and my car was totaled. I called Honda customer service they assigned an investigation ticket but after several follow up nothing happened. CA Attorney General office referred me to you.

Blackstone Lab reports fuel in my oil (acceptable for city driving} however all my driving is highway driving. Car has 22,500 miles, that oil had 4,000 miles on it and had 1.3% fuel ALL highway! Back and forth between Columbus, Ohio and Wyandotte, Michigan. Emergency Breaking will alert and apply break with nothing is in the way, and will NOT assist when something is right in front of car.

There have been 3 times that this has happened. The first time I was driving and no car was in front of me. There was a car parked off to the side and my car sensored the car off to the side and the emergency braking system came on. My car slammed on the brakes automatically and I was going 45 mph and the seat belts locked up, while my car dived forward. I had to slam on the gas to avoid someone rear ending me behind me on a busy road. The other two times this happened occurred within 2 days of each other. The first was in broad daylight and my car sensored a shadow on the road, setting off the emergency braking system, making my car automatically brake and locking up the seat belts again. I was going 65 mph on this road as it was an interstate. I had to also slam on the gas to avoid an accident. The third time was 2 days later driving at night with no one around me, and I was on an exit 3 minutes away from my apartment. I’m not sure what set off the emergency braking system this time, as I didn’t see a shadow since it was dark out, but once again, it came on, locking up the seat belts. This time I was going 35 mph. I’m lucky each time I was able to get out of it and avoided an accident but I am truly scared to drive my car as this happens out of the blue when the cruise is not on or whether the cruise control is on.

I took my 2019 Honda Civic into the dealership because I got a warning signal that says, collision mitigation system problem. The dealership says it needs a part that is back ordered and told me I could drive vehicle until part comes in. It has been several weeks. I am not comfortable driving my vehicle with this warning light on plus whatever they did since I assume this is a vital safety component/system. Also0, I have no cruise which makes long trips uncomfortable.

The emergency braking system auto brakes when to close etc mines done it multiple times with car ahead of me by 2/3 car lengths and even while switching lanes it’s auto brakes for no reason

MOST RECENTLY, DRIVING ALONG ON A SUNNY DAY AT ABOUT 45 MPH ON A FLAT ROAD. NO OTHER VEHICLES ON THE ROAD IN SIGHT. THE COLLISION WARNING SYSTEM BEEPED AND FLASHED THE WARNING ON THE DASH. AT THE SAME TIME THE SYSTEM ENGAGED THE BRAKES MOMENTARILY BEFORE DISENGAGING. THE BRAKING LOWERED MY SPEED TO ABOUT 30-35 MPH. THE ONLY CONCLUSION I COULD REACH WAS THAT THE SYSTEM MISTOOK THE SHADOW OF A TREE FOR AN OBJECT BUT I HAVE NO WAY TO KNOW. THIS HAS HAPPENED BEFORE WHEN TAKING AN EXIT RAMP FROM A HIGHWAY WHEN THE COLLISION WARNING FLASHED AND THE SYSTEM ENGAGED THE BRAKES MOMENTARILY, DROPPING MY SPEED SOMEWHAT, BEFORE DISENGAGING. IN BOTH CASES, I DO NOT KNOW WHY THE SYSTEM DISENGAGED, THOUGH I AM GLAD IT DID AS OTHER VEHICLES APPROACHED FROM BEHIND SOON AFTER.

1.The Automatic Breaking System malfunctioned, and is available for inspection upon request. 2. Safety was at risk because in March 2020, the car stopped itself on North Carolina route 70 in the middle of traffic without warning and without cause/reason. 3. Dealership inspected the system on April 1st, 2021 and found no issue. They told me to manually turn off the system every time I start the car. 4. No, the car was not inspected for the ABS by the manufacturer, police, insurance, or anyone else. 5.No warning lamps, messages, or other symptoms were on. Finding this article has prompted me to pursue the problem again. https://myfox8.com/news/money-matters/over-1-7m-hondas-investigated-for-unexpected-automatic-braking/?utm_medium=referral&utm_campaign=socialflow&utm_source=facebook.com&fbclid=IwAR3h1YQ5WtFCpKL7VaZ4jB2gP4TmhAukrSG72UX_7pLXQF7XN4bMQIWITDc

EVERY TIME I DRIVE AT LEAST 30-35 MILES I GET THE MITIGATION, COLLISION AND ACC PROBLEM IVE TAKEN THE CAR TO HONDA 3 TIMES AND THEY ARE NOT ABLE TO FIGURE OUT THE PROBLEM. I'VE PAID FOR THEM TO RECENTER THE RADAR SENSOR BUT THAT DIDN'T WORK NOW THEY ARE REQUESTING I REPLACE RADAR FOR $1,500. THIS CAR HAS 40,000 MILES ON IT WHY AM I HAVING ISSUES ALREADY? ONCE I TURN THE CAR OFF THE ERROR MESSAGE LEAVE BUT ONCE I GET TO THE 30-35 MILES IT COMES BACK UP.

I WAS DRIVING ON AN EMPTY ROAD WITH SPEED LIMIT 40 MPH. IT WAS 2:30 PM WITH SUNNY CONDITIONS. THE CAR STARTED BEEPING AND THEN THE CAR'S BRAKES AUTOMATICALLY ENGAGED VIOLENTLY. THERE WAS NO CAR, PEOPLE, ANIMAL, DEBRIS ANYWHERE IN FRONT OR TO THE SIDE OF ME. IT IS AN UNSAFE CONDITION BECAUSE A CAR COULD HAVE BEEN BEHIND ME AND REAR ENDED ME BECAUSE OF THE SUDDEN BRAKING.

The contact owns a 2019 Honda Civic. The contact stated while he and his wife were driving at various speeds, the vehicle would independently come to a complete stop. The contact was uncertain if any warning lights were illuminated. The contact stated that the vehicle resumed normal operation after failure. The contact had taken the vehicle to a dealer where they were unable to diagnose the failure. The failure persisted. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 15,000. The VIN was not available.

I have had the accident mitigation system trigger for no reason causing the vehicle to slam on the brakes and come to a complete stop or close to a complete stop on two separate occasions. The first time this happened the vehicle had relatively low miles. I was driving down the road on a sunny day and the vehicle slammed on the brakes. The second time this happened I was driving to work right before the sun rise. The vehicle again slammed on the brakes all by its self. Thankfully no one was behind me either time.
