What 1,812 owners told NHTSA about the 2018 Honda Accord Fhev

• 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.

NHTSA ODI 11660565

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.

NHTSA ODI 11657475

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.

NHTSA ODI 11655501

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.

NHTSA ODI 11654917

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.

NHTSA ODI 11654344

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.

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.

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.

NHTSA ODI 11641844

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.

Getting a dash warning that all mitigation systems are not working and to see my dealership

NHTSA ODI 11632326

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.

NHTSA ODI 11628912

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.

NHTSA ODI 11628264

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.

Cam position sensor on bank 1 went out at 75k miles. Causing the vehicle to go into a sort of limp mode. The only way the issue was temporary fixed was if the battery was unplugged and plugged in again and the engine was up to operating temperature.

NHTSA ODI 11623635

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.

NHTSA ODI 11622127

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.
