Assist problems of the 2019 Honda Accord

There is loss of power when accelerating and all the warning lights are staying on when the car starts which is disengaging all of the advanced driver assistant systems.

Wednesday 10/01/25 I was driving to work on the highway with cruise control on, it was a empty road with nothing in front or behind me, my steering wheel got yanked out of my hands and turned all the way to the right towards the guard rail, then the steering wheel got yanked all the way to the left automatically, I did a 180 degree spin and crash my 2019 Honda Accord touring 2. 0l. I believe the lane keeping assist system (lkas) was at fault as well as the collision mitigation braking system (cmbs). The vehicle got towed off the highway directly to a local body shop. The vehicle is available for inspection upon request. Mine and others safety was put at risk because the vehicle decided to crash itself potentially killing me or other people. The vehicle just arrived at the body shop and no diagnosis has been done yet. The vehicle is not drivable so the problem has not been reproduced. Vehicle has not been inspected and looked into yet, I am waiting for the body man to do a deep dive into it or I am planning on bringing it back to the dealership. There was no warning lamps present.

With my 2019 Honda Accords I have had this car going on 4 yrs and now all my dashboard lights are on . . And stay on . Seltbelt lights , lane lights , brake, check engine light and light u can think of it's on in this car and it's not just my car.

All warning lights turn on on the dash board. I replaced the battery, airbag module, and abs module and I'm still having the same issue.

I bought this 2019 Honda Accord on June 30th from a company called greenville motor company. July 1st, I took the car to the Honda dealership to get a diagnostic to make sure everything was in good shape. The technician I spoke with did notice the car & stated that it had a problem with the previous owner which was the injectors. She told me that the light may not come on now but it may come on in the future. After I left the Honda dealership, I went to greenville motor company & showed them the diagnosis I had done at Honda. He said he didn't see anything wrong. On July 2nd, all of my dashboard lights came on. Took it back to greenville motor company, the tech there said I could pick it up July 3rd & drive it over the weekend. (basically he reset the lights so they wouldn't come on for a certain period of time). Within this time period I took it back to the Honda dealer & they told me that I also needed a turbo, they gave me the printout for that as well. Took it to greenville motor company, they agreed that I did. Need a turbo. Manager says he ordered turbo. I I don't remember the date I took it back but on July 12th, my dash lights came on again. I took it back to greenville motor company July 14th, July 18th greenville motor company called & said something on top of the turbo wasn't screwed on thats what was triggering the turbo code to show, so he never put on the turbo that he ordered I had it 2 hours & my dash lights came on again.

The vehicle has an emission system error along with all other errors, car also hesitates to accelerate. Yes it is dangerous a failing turbocharger can result in a noticeable decrease in engine power, especially at higher speeds. Diagnostic : confirmed by dealership. The car was looked at the dealership mechanics nothing happened to where I need any others. It’s just been lagging getting up into speed etc. It popped up a month ago the emission light and went away. Came back two days ago which today is 6/20. Engine system problem tire pressure monitor system electric power steering problem cmbs problem adaptive cruise control problem cmbs problem all lights flashes on screen.

Hi. All the warning lights came on one morning. Looking online many people are have the same issue.

I have was called steering sticking in my steering wheel when I’m driving and it stuck straight and I have to turn it a little bit. I have to kinda yank it just a tad bit because the steering is sticking is an issue with other Hondas. I’m having it also.

As I am driving over 50 mph in traffic my 2019 Honda Accord will automatically brake in the middle of traaffic almost causing accidents. The mitigation system will fail and prompt on the cluster electric parking brake problem, electrical power steering problem, rdm problem, cmbs problem, adaptive cruise control problem this so called safety features are being a safety problem.

On March 21st, 2022, I was driving between 35-40mph in clear conditions. I had adaptive cruise control, and lane mitigation on. My vehicle flashed “brake” on the instrument cluster and hud. The vehicle slammed on the brakes. The braking force was strong enough to lurch me forward and in the process of the vehicle braking, my steering wheel veered to the left and I almost hit a divided barrier. There were no cars in front of me or any obstructions in the way that would have activated the emergency braking. This is the second time in a year my car has done this, but the first time that the braking changed the vehicle’s direction.

I filed a complaint about this vehicle in October of 2020 when it was 5 months old at that time because it would slam on breaks and jerk the steering wheel for no known reason and with no one around. It has continued to do this intermittently as well as other erratic driving that cant be accounted for including at times getting confused when passing exit ramps where the car will slam on breaks and jerk to try to exit. I was driving this afternoon at highway speeds and the steering wheel began to shimmy (vibrating back and forth). It felt like there was a potnetial tire blow out but my tpms did not indicate any loss of pressure. I assumed the car was having another one of its unexplained steering behaviors. I know from previous experience that turning the blinker on will stop the shimmying if it thinks you are trying to switch lanes so I turned my blinker on and I moved over one lane hoping it would stop. The shimmying (vibrating of steering wheel) continued and shortly there after it pulled hard left on me driving me directly into a cement barricade that was located a few feet off of the side of the road. I hit the barricade at highway speed and bounced off of it spun around and re-hit the barricade with the rear of the car which is what sustained the majority of the damage when it hit. Though I hit the barricade with significant force the airbags did not deploy. My daughter has been in the car with me on a previous occasion when the car has done this and I have complained about it numerous times to numerous people. I do not feel safe in this car. . . It only does this at highway speeds and on the highway. . . It will kill me or someone else if something is not done. I have contacted Honda cooperate and also filed a report with them as well.

Dashboard shows multiple warning functions that is disabled in the vehicle such as lkas, collision mitigation braking system problem, road departure mitigation system problem, blind spot information system problem, auto- high beam problem, transmission system problem, performance may be reduced, electric power steering system problem, adaptive cruise control system problem.

Numerous times while driving on the interstate at 65-75 mph the vehicle has braked hard in the highway. No cars beside or in front. The last incident I was almost rear ended by a Toyota tundra who barely was able to stop. I took the car to vann york Honda, was told it was a recall for a bcm module (obviously untrue, that is for wipers, rear defogger, etc), but I did get the issue documented on paper. This was if something happens to me, I or my family have documentation that the car does have an issue with braking at high rate of speed for no reason. At times the brake light comes on, the last two times lane departure light has come on and I have been centered up in my lane, no one in front of me or as I stated beside me. The car is a danger to the driver, any potential passengers and the vehicle following. Honda seems not to be concerned as I have read online in many places that this began with 2018 models and affects not just the Accord, but the civic as well. My 75 year old mother has a 2019 civic that is doing the same thing. I suppose if someone gets hurt and families start to sue, Honda may do something. Now that I have documentation, if I get hurt, that is my plan!.
