general problems of the 2018 Honda Accord - part 1

While trying to accelerate the car loses power. This has happened many times. The Honda dealership has said the system is on back order and they will call me when it’s available. It’s been months. The “jerks”a few times then the check engine light comes on then the car loses power. The dashboard lights are brake system, emission system, electric power steering, hill assist and acc system problem.

My car be braking and nothing be in front of me. It detects something in front of me when nothing be there.

I had been driving down highway and all of a sudden my car put on brakes hard. Thank goodness no one was behind me. I had dealer turn off that feature so it wouldn't happen again. I still experience my brake light flashing when nothing in road to brake for but doesn't brake on its own. Issue having now is issues starting car and once it starts I recieved a collision mediations issue pop-up on display saying see dealer now. Cruise control issue, and on dash has traction control saying ignitionating continue driving. The braking issue started right after purchase in 2018. The starting issue started yesterday 7/25/2025.

Parking brake suddenly engaged while in traffic car would not move. Car had to be towed brake pads were replaced but mechanic stated parking brake had defect that only the dealer can repair.

Driving down the road, no cars or obstacles in front of me. Out of nowhere the automatic emergency breaking came on. The car slammed on the breaks and very quickly came to a complete stop in the middle of the road. If there happened to be another car behind me they would have rear-ended me. There were no warnings prior to this happening.

The contact owns a 2018 Honda Accord. The contact stated that while driving at an undisclosed speed, several unknown warning lights illuminated. The vehicle was taken to a local dealer, where it was diagnosed; however, no cause for the failure was identified. The contact stated that while driving at various speeds, the vehicle jerked abnormally. The vehicle was taken to a local independent mechanic, and it was diagnosed and determined that the core pad needed to be replaced. The vehicle was repaired; however, the failure persisted. The manufacturer was made aware of the failure. The failure mileage was approximately 111,000. The VIN was not available.

When I am driving in an area near my home with road construction- there is a certain area that has a metal plate in the road and when I approach in from the east my car will automatically brake hard. Luckily this has not caused an accident but I suspect that it may because it is a busy road.

During interstate driving vehicle detected both road departure and engaged the emergency automated braking. The vehicle attempted to correct the "road departure" by steering the vehicle away from the perceived problem and engaged the brakes nearly causing a collision as it has done numerous times before. I have reported this to NHTSA and american Honda and await a repair of this dangerous issue. Honda has opened a case on this but have had 6 months and no response has been issued.

My 2018 Honda Accord sport has been experiencing issues with its automatic emergency braking system, specifically the collision mitigation braking system (cmbs). The system has been activaing unexpectedly, causing the car to brake without an apparent reason. I’ve been trying to keep a list of locations that it has happened and it usually occurs under overpasses when the light changes from light to dark. I’ve reached out directly to Honda and the dealership and neither took my inquiry seriously.

The collision mitigation braking system is engaging while I’m driving with no obstructions in front of me. The car slows down completely while I’m on the highway almost coming to a complete stop. This has happened numerous times since Dec 2024. I took it into Honda and they did absolutely nothing besides charge me over $500 for diagnostic fees and told me to get an oem battery and bring it back to be inspected again.

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.

Doesn’t run as it should,all lights and warnings show on the dash.

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.

Randomly, my car will start throwing many warning signs when I crank my car. Then it magically disappears after 2 days. Also I drive my car past 40mph and the engine light came on and then I could no longer accelerate. My car was slowing down while I was on the freeway. I pulled over, turned my car off then back on. Everything is back to normal. Next day, I crank my car, warning signs again and then disappears. I took my car to the auto shop and they could not find any codes. I have videos and pictures. There’s also a Honda facebook group with my same model car reporting the same behavior.

Dashboard lit up with a lot of lights and stuff.

While driving on highways, with no one in front of me, vehicle will brake while I have my foot on the gas. Vehicle says brake system malfunction. When I let off the gas and push again, it'll accelerate for a second, then brake again even though my foot is on the accelerator.

The rear brakes are horrible. They wear so quick. This is my 3rd Honda Accord and I’ve never replaced brakes this much on any Accord I’ve ever owned. Back tires also wear really fast. The rear brakes squeal really bad and makes squealing noises when I’m driving. No brakes are being applied but the noise continues. I’ve had this car for 3 years and I’ve changed brakes 3 times which is ridiculous.

Adaptive cruise control - collision mitigation - road departure mitigation - vehicle stability assist - hill start assist - electric parking brake - tire pressure monitoring.

While traveling at approximately 30-35 mph, my vehicle suddenly and abruptly stopped, flashing the word "brake" on my dashboard. I was traveling in the right lane on a four lane road, with no vehicles in front of me or to the left of me. There were no pedestrians near, the road was free from any hazards and the road ahead was clear of any potential hazards that may require an abrupt halt. I was properly restrained, but my safety and the children I travel with could have quickly become compromised if hit from behind. Additionally, everyday items such as my school bag, water bottle and my children's books that I keep in my vehicle came flying forward, obstructing my ability to properly operate my vehicle. Additionally, being that this was unexpected, I was pretty shaken up which compromised my ability to safely operate my vehicle while attempting to find a place to park my car. My vehicle was not inspected and I used my owners manual to turn my collision mitigation braking system off in order to safely arrive at my destination. Additionally, there were no warning signals or messages that indicated this issue before it happened.

Multiple times in the state of oklahoma, driving from oklahoma to maryland, and in maryland washington DC area, the automatic brakes apply at highway speeds on the interstate whenever there is a shadow in the road. It is extremely frightening. I am having the fuel pump recall repaired at the Honda dealership today. I told the Honda dealership about this problem and they said they were unaware of it. They said they would reset the calibration on the anti-breaking system. However, upon research, it looks like you are investigating this problem. Please add my car to the list of cars affected. I do not know the exact dates that this happened but it has been. I would say at least 20 to 30 times since 2020 when I bought the vehicle.

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.

All warning lights came on (check engine, emissions problem, brake problem, tire pressure monitoring system problem, cruise control problem, brake problem, steering wheel problem, and lane keeping assist problem). In addition, sometimes the vehicle will vibrate or shake when first turned on and at times, when braking, the car will shake or vibrate.

2018 Honda Accord twice last week my car suddenly braked with no obstruction in front of the vehicle. I was on a straight section of the roadway. Thankfully no one was directly behiind me. It appears there have been other incidences reported.

Every light on my dashboard is on I done took it to Honda an had the lights turned off server times still on.

During regular driving, the vehicle engine will stall and lose power, with 9 different warning lights coming on and all advanced driver assistance systems becoming disabled, and I believe abs brakes being disabled as well. This is due to cylinder 3 misfires and the problem is intermittent, but the loss of power can come on randomly and is dangerous on highways as you have to pull over due to the sudden loss of engine power, restart the car, and hope the problem temporarily goes away. The l15be engine used in 10th gen Accord engines is widely known to have a faulty engine block design leading to early head gasket leaks (see links) which results in misfires and I think it is imperative that Honda issue a recall as thus far, they have been ignoring the pleas of the owners. I am planning on replacing the gasket ($4000 personal mechanic. Honda charges closer to $6000) with aftermarket parts ($400 additional) as replacing them with oem parts would just allow this to occur again. Please contact me for more details. . Read more...

When the vehicle in front of me slows down significantly, my Accord will flash the automatic brake warning and come to a complete stop. Once stopped the vehicle does not accelerate for a few moments. Several times I’ve pressed the acceleration pedal to the floor with no acceleration, the vehicle in front of me long all while watching cars swerve behind me to not rear end me. The several times this has happened the vehicle has left me completely stopped in heavy traffic, the middle of an intersection, or lastly an empty road as the vehicle stopped for a median….

The vehicle is stalling while driving to a point where on the freeway it slows down to 10 miles per hour to all of the sudden have all the emergency lights on that come to a sudden stop. I have called 3 different Honda dealers, they said that they need to check what is wrong with the car first making it clear that there is a fee of $220. My daughter has been driving the vehicle in very unsafe conditions. On Friday may 24th we were on our way to oakland from the ventura county (I was the passenger) and in less than an hour driving the car started stalling to come to a sudden stop on the freeway. I took the vehicle to the ocean Honda dealership the following week driving forcefully the car at 20-30 miles because we could not afford another trip on the towing truck. The service person drove the car from the parking lot to the front of the service office (less than 50 ft) and the lady said the car was in perfect condition and not one emergency light was on! I shared with them images of all the emergency lights were on in the vehicle and as well as at least 4 codes. We left the car and then they called me to notify that there was an issue with the injectors and that the vehicle was still under warranty for those parts because it is under 70,000 miles. The next day the vehicle was given back to me. I asked about the replacement of the gas pump, and they said because the vehicle is not having any issues it cannot be replaced. That night the car stopped on the freeway, I took it back and now they said it was the spark plugs. I decided to take the vehicle to a different dealership. Now at dch Honda today the injectors were replaced and the car still stalling and stopping. They recommend replacing the spark plugs ($350 they will charge) and I told them I will take it to my mechanic. They said, "but you know the car is not fixed even if they replace them". I said you are telling me this safety issue is that so what is it? nobody willing to change the gas pump!.

We purchased the vehicle new from our local dealer. The vehicle has randomly applied the brakes for no reason. It doesn't happen predictably and can sometimes be a severe or a strong application of the brakes. It is typically a quick application then quick release. Sometimes it will apply the brakes for a close vehicle in another lane. I'm concerned someone will rear end me. It's scary and very unsettling when it happens. I can't tell you a date when it last occurred. This submission form will not allow me to continue without selection a date, so I'm choosing today's date.

As I was driving down the street, the automatic emergency braking system was activated and brought my vehicle to a complete stop! there was no vehicle directly in front of me and it almost caused the vehicle behind me to slam into me had they not veered into the other lane of traffice to avoid rear-ending me. I could have easliy been rear-ended and injured and/or caused several accidents as a result of this. The aeb sytem has activated before with no apparent reason, but this was the first time it actually came to a complete stop. Fortunately, I was not on the highway at much higher speeds as this could have had serious and possible deadly consequences. There have no been warnings or indicators previous to this incident that would have alerted me that there may be some type of issue with this system.

When the adaptive cruise control is engaged there are times that the vehicle will brake by itself when there is no vehicle in front of me. I drive 52 miles one way to work and then home daily. This happens at least once almost every time that it is used. As for the blind spot warning it randomly will go on and off saying an object is near especially when parked at red lights with none of the vehicles moving around me.

The contact owns a 2018 Honda Accord. The contact received notification of NHTSA campaign number: 23v858000 (fuel system, gasoline); however, the part to do the recall repair was not yet available. The contact stated that the check engine warning light, the brake light, and other unknown warning lights were illuminated. The vehicle was taken to the dealer, where it was diagnosed that the fuel injectors had failed. The dealer charged a fee for the repair; however, the contact declined to pay for the repair and advised the dealer to complete the recall repair. The vehicle was not repaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the failure and referred the contact to the dealer for diagnostic testing. The failure mileage was approximately 96,000. Parts distribution disconnect.

2018 Accord consistently has the warning pop up for the the crash mitigation system and tells me to visit the dealer. Cruise control just stop working while driving. When I turn the car off and back on it resets, and then 10-20 miles goes by and the error pops up again. Incredibly unreliable and unsafe when I’m on the freeway going 70. This has been a constant problem.

I have a 2018 Honda Accord. I have had issues with it breaking and nothing being there. It has cause me to almost get rear ended several times and I find it to be a huge safety hazard. I will be driving down an open road and nothing will be in front of me. My car will randomly slam on the breaks and it scares me terribly. This has happened quite a few times now. At first I thought it was a fluke but it has continued to happen and is becoming a major issue.

On February 24,2024, while I was driving from st. Petersburg, FL to tampa, FL, I experienced phantom breaking on the highway. The vehicle gave brake warning and started breaking automatically. Fortunately, I accelerated and maintained my speed thus avoiding a rear end accident. I realized that there is an ongoing inquiry related to these incidents but I thought I should come forward and write to you for everyone’s safety.
