2021 Honda Accord Driver Assist & ADAS Problems

There are two locations in the town I live where I am driving under a bridge, and there is a dark shadow on the road from the bridge. My car’s accident mitigation braking system turns on at these locations and suddenly brakes the vehicle. This is not safe as people are traveling speed limit around me and I can cause an accident this way. About a month or two ago, the car behind me almost hit me at one of these locations when my vehicle’s automatic braking system turned on. It was made to prevent accident and brake if there is a vehicle, but because it is braking due to a dark shadow coming, it is not working properly and needs to be looked into. I called Honda and they want me to pay hundreds of dollars at my local Honda dealership for a diagnosis, I do not feel like I should be responsible for that fee as this is a safety feature that is not working as it should and instead making it less safe for me and drivers around me.

The contact owns a 2021 Honda Accord. The contact’s spouse stated that while driving at an undisclosed speed, the Lane Keep Assistance feature became inoperable. The contact’s spouse stated that the feature was erroneously activated and deactivated. The contact stated that while the LKAS was activated, the vehicle jerked abnormally. The contact expressed concerns about the failure. The contact stated that the safety feature was very hazardous and could pose a risk to the driver and other vehicle operators. The vehicle was taken to the dealer, but was not diagnosed or repaired. The manufacturer was made aware of the failure, and a case was opened. The approximate failure mileage was 60,000.

My car slammed on its own brakes hard out of nowhere with nothing in its forward. The first time it happened was about 9 months ago while I was driving on the highway, it was a quick moment of breaking without any reason, but the car didn't stop. Today it happened again, the speed was about 30 m/h, the car slammed hard on the brakes to an almost complete stop. I was lucky, nobody was behind.

The contact owns a 2021 Honda Accord. The contact stated while driving at approximately 30 MPH, the vehicle independently slowed down as if the brake pedal was depressed. The contact stated that a warning for the brakes and the collision mitigation and check engine warning lights were illuminated. The contact had the vehicle towed to a local dealer, where it was diagnosed and determined that the turbo charger needed to be replaced. The vehicle was repaired. The contact retrieved vehicle however, several warning lights were illuminated. The contact parked the vehicle and had not returned it to the dealer. The vehicle was not diagnosed and was not repaired. The manufacturer was informed of the failure. The contact researched online and related the failure to NHTSA Action Number: EA24002 (Forward Collision Avoidance). The failure mileage was approximately 98,000.

Lanes on the roadway were adjusted for a workzone. Because of these lane adjustments, a large amount of crack sealer was used on the roadway. The car confused the crack sealer as roadway markings and tried to slam on the brakes in a workzone, thinking I was going over the lines, unless I used the turn signal to override the automatic braking, which is the only way I was able to avoid getting rear-ended. This ian't the first time this ecent has occurred in my vehicle.

steering wheel jerks hard out of my hands. Car, especially in direct sunlight jerks the wheel thinking that I'm not in the center of my lane, even though I was centered. Hard to control the car.

The contact owns a 2021 Honda Accord. The contact stated that while operating the vehicle, the infotainment center screen malfunctioned, causing the backup camera display to glitch and become distorted. The vehicle was taken to the local dealer, who diagnosed that the infotainment center display was faulty and needed to be replaced. The infotainment center display was replaced, and the vehicle was repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 74,716.

Automatic breaking engaged with foot already pressing down brake pedal as traffic ahead was slowing. The automatic braking was overkill that the traffic that was slowing down ahead of me was now pulling away.

Lane departure continues to jerk the wheel out of my hands while driving into direct sunlight. Car thinks its not in it lane an jerks the wheel pulling my into another lane if I don't fight back.

Lane centering continue to jerk the wheel so hard it almost pulls the wheel out of my hands. In direct sunlight the issue is severe. Honda refuses to fix and wont fix recalls for my Accord. Honda is claiming it will take 4-5 years to fix recall on my car.

Lane keep assist continues to jerk the wheel from my hands with false lane departure warnings. Especially in direct sunlight. THIS HAS BEEN REPORTED TO YOU 100'S OF TIMES AND NOTHING HAS BEEN DONE FOR 4 YEARS. HOW MANY MORE PEOPLE HAVE TO BE KILLED AND INJURED IN HONDAS BEFORE YOU ACT?

My honda Accord’s automatic braking system suddenly engaged this morning for no reason. The driver of the car following me had to slam on his breaks to avoid rear-ending me. If the other driver had not stopped, we would both have been injured. Honda’s emergency braking system is dangerous. There should be a way to disable it permanently.

I was driving 40 mph and slowed down gradually pressing my brake due to a car making a right turn. As I'm slowing down to probably 15mph, the brakes wording shows on the odometer display. i had plenty of room between the turning right car but suddenly the car automatically stops while I'm in the lane. I could of got hit if there was a car behind me. This is the 1st time it has happen. I've seen the brake wording show up a few times while driving but this is the 1st time the car stopped on it's own. Currently researching on how to turn off the brake assist for the car. (This is a safety issue for other Accord owners)(purchased car DEC 2023)

I was driving down the highway at approximately 70 mph and a vehicle ahead, probably 8-10 car lengths lightly applied their brakes slowing down to my estimate of 60 mph. The forward collision activated and slammed my brakes causing a pickup behind me to slam on their brakes and swerve onto the shoulder to avoid a collision. This is not the first time this has happened, but the previous time the braking wasn't as severe.

I was driving 35mph and there was nothing in front of me when my car stopped. It would not move forward or accelerate despite pushing on the gas pedal. There was no forward motion or propelled motion. It took several seconds for my car to go again. The car was towed and serviced at the dealership. They said the front sensors had misfired. If a car would have been behind me or if I had been on the highway, this would have been a serious accident. The engine light never came on. A series of 5 warning lights related to the assisted driving came on but went away.

While driving on an open road with no cars around, the emergency braking suddenly engaged causing the car to come to an almost complete stop by itself.

At speed limit cruising down I66. I was all alone. No birds in area at all. Open road. I was in middle lanes. Car attempted to come to a complete stop by itself. “Phantom Braking”? All my friends with Honda’s and Acura’s mentioned similar issues. If anyone was behind me, I could have caused a pile up or even worse. It’s happened a few times. Took to Capitol Heights Honda and Landmark Honda. They ran diagnostics. Explained to me there were no error codes. I explained to them, if system has a fault, it thinks it’s operating properly. So, no errors would appear! I have experience and education in computer programming (College), mechanical and electronic (US Army) and over 30 electromechanical troubleshooting, repair and maintenance and other IT experience. SME After they haven’t been able to do anything about it, I turn off all safely systems. I drive a lot. So, I’m also a very good driver. Have almost 65k miles on my vehicle. Date of incident below was when I forgot to turn off sensor. But it happened a few times before and I brought to Honda after first two times. I even had to rent a car at my expense.

My family and I were driving home to LA from NM. I had been using the cruise and steer assist earlier in the drive but had it off after going through a metro area interstate. There was no vehicles within the cars front camera system when while driving 75 mph( that was the sped limit in TX), the cars braking system engaged with a hard break, no “brake” light flash of rapid break pumps as it would do if something was within the camera range. I was able to get in slow lane and within 30 secs it did it again. I was able to drive another hour with no issue but stayed under 65mph. We are 7 hours away from home and will be getting it to the dealership. This could have caused a major wreck.

A vehicle in front of me made a quick slow down. The automatic braking engaged, the driver behind me did not react in time and struck the back of my car. Resulting in totaling of the vehicle. The automatic braking would not stop engaging, if it would have dis-engaged I could of pulled forward a few feet and the driver behind me would of missed me.

I was traveling on interstate 10 going around 50mph with a safe distance from the traffic in front of me. The car in front of me did break but then sped off immediately. My car's automatic emergency breaking system engaged very aggressively and unnecessarily (a front end impact was not imminent if my car had not braked). I tried to accelerate but I had no control over it. The sudden breaking caused my car to slow so rapidly that the freightliner behind me did not have time to react, causing him to rear end my car. The car was totaled as a result. I have front and rear dash camera footage showing all of this. ***I marked a document as the police report to proceed but I do not have a copy of the police report.
