2018 Honda Accord driver assistance complaints
Page 4 of 15: complaints 71 to 100 of 403, newest first, as owners wrote them.
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 the federal safety agency 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.
This is about the 5th time this has happened to the car. All warning lights appeared spontaneously while driving. The lights would turn off if the car was turned off for a long period of time or is we disconnected battery for a long period of time. We have tried to research the problem and no one seems to know what the cause or permanent fix is.
The vehicle was totally inoperable and suddenly came to stop was lucky that was driving in a local road where there was no vehicle, suddenly all different warning signs were coming on the dashboard and couldnt drive at all and vehicle was totally stalled. it was very dangerous situation luckliy i was just came off a very busy road otherwise coudl have been major incident. Currently the vehicle is at dealership nto sure what they will say but just wanted to report this as it is very dangerous situation
• Head gasket • None of the safety features work when there is a head gasket issue. Power steering is reduced as well as break performance • Confirmed by Honda dealership with a Boroscope • Honda • No warning, Honda at first thought it would be fixed by fixing the factory recalls. Light went away prior to taking it in and then looked in to it 2 weeks later and diagnosed head gasket failure
UNKNOWN I received the notice that there was an active recall on my 2018 Honda about the 1.5 Fuel Pump. I have scheduled several appointments to fix this, only for Honda to cancel all appointments related to the recall, stating they didn't have the part. I was headed to work, and every light on the dashboard that could come up, came up. There were several warning lights from brakes, transmission, collision, engine, etc. I took the car to the dealership, and they discovered that the fuel injector was the culprit. I am outraged because they're denying there's a connection, and I believe otherwise.
I purchased this 2018 Honda Accord that has had no major problems until the last 6 months. I purchased the car from Gerald Jones Honda and have had all repairs and maintenance done there with the exception of tire related concerns and occasional oul changes. All the issues I've experienced have been engine related and in the same area of the engine. Consistent leaks, repeated warning lights, and loss of speed. I have replaced fuel injectors, a head gasket, and a turbo in the last 6 months. Despite those repairs, I'm still experiencing leaks and flashing warning lights. Honda currently has my car due to warnings again. They have indicated it is a performance issue but can't locate the problem. Even suggested I continue to drive the car as they have been unable to duplicate what caused it. I told them to keep it because that makes no sense for me to drive it as it seems unsafe to do so and I could potentially make matters worse. I've spoken to several 2018 Accord owners who have experienced the same issues. This is very concerning to me and crippling my finances. Honda stands out for their reliability, but regrettably the 2018 1.5L turbo doesn't stand up to Honda's reputation.
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.
My vehicle is stalling out. The engine failed. I was traveling and had to pull off the interstate and stop and restart vehicle. It was very dangerous as traffic was going at a high rate of speed. Yes the vehicle has been confirmed by a dealer. Yes all the warning lights are on in the vehicle.
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.
Warning lights come all across the dash stating to see the dealer. I have taken it to the dealership and the issue is the fuel injector that causes the warning lights to go off and on at random. I still have a warranty of my car and was told the warranty does not cover that part. This is happening to a lot of honda accords but there is no recall for it. There is a safety issue for driving because they stay on and then go off and come back on again. This is unfortunate and unacceptable from Honda as a whole. I bought the car in May 2024 and the warning lights came on a week later and have been ever since off and 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.
The contact owns a 2018 Honda Accord. The contact stated while the vehicle was parked, the rearview camera became inoperable. The contact stated that the rearview camera failed to function properly, and the camera image appeared blank. 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 failure mileage was approximately 220,000.
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.
Failure in road monitoring camera prematurely, 70,000 ish 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.
Cars brake/mdoule automatically engaging. Brake light and brake system light constantly flashing. From what ive read seems to be a known issue that needs to be addressed or made a recall. This is a safety issue and can cause harm to the driver and others.

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.
All the lights in the car turn on. I have no clue what the problem is. I have searched the internet and have encountered many people with the same problem. With no one finding a solution to it. Honda needs to take responsibility for this. I changed the battery and have replaced the battery terminals.
The accelerator is going out when I drive. The car drives slow and pulls back while driving. Thought it was fuel pump, took it in for fuel pump recall, & the car is still doing the same thing, no change. All lights on dashboard are on. The safety of my children & myself has been put at risk quite a few times. While driving the car getting on the freeway ramp, the accelerator went out going up an hill and luckily I was able to put my emergency lights on & able to barely get over to the right side. My car almost stalled. I’ve taken it to the dealer a few times. When I took it to fix fuel pump recall, they said 2 other codes were coming on. I took it in again this past week to check those 2 codes hoping to get it fixed & he said now other codes were coming up. They couldn’t seem to find the problem. The guy said they had been working on it since 9am and it was almost 4 pm when I talked to him. He called me an hour later to say it could possibly be the head gasket but not for sure. My vehicle has been inspected by the Honda dealer. When the problem first happened on the freeway warning lights came on. Warning lights on are: Collisions mitigation braking system on, adaptive cruise control problem on, hill start assist problem vehicle may roll on, vehicle stability assist system problem on, electric power steering system problem on, brake hold system problem on, brake system problem performance on, tire pressure system monitor on, emission system problem on.
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.
Vehicle emergency braking system randomly triggered, causing me to completely stop from 40mph to 0mph in the middle of a intersection. Almost got rear-ended. NO vehicles were infront of me to trigger the emergency braking system. Vehicle has not been taken to dealership yet.

The contact owns a 2018 Honda Accord. The contact stated that the backup camera was turning on and off. While reversing, the backup camera turned black over time. The check engine and ACC adaptive cruise control warning lights were illuminated. The vehicle was taken to the local dealer, who confirmed the vehicle was not covered under the federal safety agency Campaign Number:Â 18V629000 (Back Over Prevention, Visibility). The dealer provided an unknown diagnosis, but the vehicle was not repaired. The manufacturer was contacted, who opened a case and referred to the federal safety agency hotline. The approximate failure mileage was 98,179.
Getting a dash warning that all mitigation systems are not working and to see my dealership
I was traveling down the road and I passed a bus that was in the right lane. I think when I reached the bus shadow that’s when the automatic brake warning came on and then my car went from 50 to 15mph instantly tossing everything in my car and hurting me neck.
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.
When driving, the car will suddenly slow down and automatically will apply brake. Then, the warning light will pop on the dashboard. When I run the diagnostic, it shows that the car has C0023-12: Brake Diag Circuit on Failure.
