Every light on my dashboard came on at once. I took it to a Honda dealership for a diagnostic check and they said it was my turbo but every light is still on.

While driving on the interstate, suddenly got 6 different ‘warning’ messages on the dashboard. Most of them involved the brakes. Emergency brake malfunction, brake hold malfunction, forward collision malfunction, adaptive cruise control malfunction, brake system malfunction (use of brakes may be reduced), and road departure mitigation malfunction.

All warning lights have turned on my dash. Ive done research and this is happening a lot of people that own 2018-2020 Honda Accord 1. 5l.

The car is braking even when there is no obstacle or vehicle ahead. I have not driven at higher speed but I fear that if that happens, it can cause incident and injury.

All of sudden, no incident, no accident, a lot of things were disabled such as adaptive cruise control , forward collision warning , lane departure warning and more while I was out of town (long range highway travel). When I went to Honda dealership, they blamed a few things and fixed them (expensive), then they said that the front camera needed a calibration. It was expensive. After that aiming correction, everything works fine. The camera was not broken. It just needed recalibration, and it costed about a thousand dollars. I would say it was caused by the poor design, which is Honda's fault. I googled this issue and found a lot of Honda owners had same issued and charged 1k ~2k for it. I will report it separately, but my Honda odyssey has the exactly same issue now. I have 2 Honda cars, and both of them have the same issue. I strongly suggest that Honda should recall their front camera and they should reimburse the expense we already paid for it.

All dash lights are on and the Honda dealership told me I have a blown head gasket, need a turbo replacement & fuel pump in which I wasn’t able to drive the car for 7 months at 112,276 miles. . This seems like a known issue for this make and model vehicle after 100,000 miles.

I recently took my car to the dealer because I have multiple messages on my dashboard saying please see dealer dealing with my brake system, electric power steering, vehicle ability assist, collision mitigation system problem, etc the dealers don’t know what’s going on with it. I recently had service done on it because of the recall with the fuel pump and even before that those messages were showing up.

I feel like my car should be under recall it’s so many other who experiencing the same thing. All of my lights are on, on the dash. Check engine light down to my cruise control not working. As I drive it’s stalling and jerking. I went to the dealership to have my spark plugs and my fuel injectors replace and it started back doing the same thing. Spent thousands just to be going through the same exact thing.

I was driving on a highway when the engine light came on and the car immediately started slowing down even though I was pressing the gas pedal. It flashed there was a failure of the brake system, collision mitigation braking system, road departure mitigation system, hill start assist system, and adaptive cruise control system. The check battery light also came on. The car decelerated on its own with brakes engaged. I had to choice but to immediately pull over and luckily was able to steer to an off ramp and into a parking lot.

My blinker won't appear on the dash. My trunk won't open. My back up camera won't come on at all. Can't adjust my exterior lights, stuck on the dimmest setting and can't change. Lights will also flicker and I have no control over it. My radio screen told me to enter a code but wouldn't allow me to. My break system light was on. There is warning reading adaptive cruise control see dealer, automatic emergency braking see dealer, lane departure warning see dealer. Doors locked and unlocked while driving. Air condition wasn't blowing the temperature it said, and acting as it was on low when it was on the highest setting. It is available for inspection upon request. I brought my car into a Honda dealership today. My car had to stay overnight because they were unable to address the problem. There were no prior problems or warnings beforehand. All these problems first appeared when I started my car for the first time on November 14, 2024. These put myself and others at risk because the doors locked and unlocked which could have caused us to get trapped in. The lights not working put me at risk at night because I could not see the road that good.

Everyday the vehicles struggles to pick up on speed and stalls out. I am often holding up traffic because I’m driving to slow. I have to very very very slowly accelerate so that the car doesn’t stall. When the trying to accelerate it often skips and jerks while driving. I often wonder if this will affect me while driving on the interstate. I fear that a bad accident is on the horizon with these issues. Could you please help. I’ve tried multiple times since last December to get the car fixed and Honda refuses to fix my vehicle even though I received a letter in the mail saying more repair parts are available.

During normal driving - clear weather conditions - the car will suddenly activate the forward collision braking. It will literally slam on the brakes and decrease the speed by 10-15 mph. This happened as I was going down the drive of our neighborhood, I was at 45 mph with no one in front of me or behind me (thankfully) and the car applied the brakes and activated the front collision warning. There is also an intermittent issue with my seatbelt. Specifically the drivers seat belt. I was witness to someone driving my car - he buckled his seat belt and it unlatched. He then buckled it again thinking he didn’t do it right - but it wouldn’t latch. This has happened to me before as well - but usually after the third try of buckling the seat belt it will work and so I thought nothing of it. Additionally, the windshield wipers do not go back to their original position after being in use.

The system failing and had problems. Had to take to Honda dealer. They had to replace the system camera.

Misfire in cylinder causes blown head gasket.

After fuel pump failed to open, top of this year my vehicle began to stall. I had the recall issue fixed 5/31/2024 by Honda dealer staten island. Just a couple days ago my vehicle started stalling again.

This is the second time in a year and a half, fuel injectors went bad an were replaced and im assuming this time is same issue. The car had a little rough idle . The car throws a check engine light and all other lights on dash come on and vehicle went into a sort of limp mode. . Car would not excellerate and all safety items will not work… the injectors went bad at 59000 miles and after being changed at dealer it looks like they are bad again at 78000 miles. . This car is dangerous because of these issues. . I am calling dealer on Monday.

Unintended activation of cmbs braking and warning system causing rapid vehicle deceleration. Deactivation of active cruise control due to cmbs errors.

Collision mitigation automatically engaged causing vehicle to brake when unnecessary. Once after excelling from a redlight and again when entering a highway on ramp. After occurring twice in a 6 month period it's now become permanently disabled with dash warnings. Braking system error. Collision mitigation breaking system error. Tpms error.
