2018 Honda Accord driver assistance complaints
Page 3 of 15: complaints 41 to 70 of 403, newest first, as owners wrote them.
I am submitting this as a formal and urgent complaint regarding serious safety issues with a vehicle I recently purchased. The trunk opens on its own while I am driving, which creates an immediate safety hazard. In addition, the backup camera is malfunctioning, further increasing the risk when reversing or parking. Shortly after reporting the trunk issue, the radio also stopped working. I have contacted the dealership regarding these concerns, but no corrective action has been taken. Given that this vehicle was recently purchased and involves active safety risks, this lack of response is unacceptable. I am requesting immediate inspection and repair of these issues, as well as written confirmation of how the dealership plans to resolve this matter promptly. Please consider this issue urgent due to the safety risks involved. I look forward to your immediate response.
Upwards of a dozen times my Honda Accord will suddenly brake as it believes I am about to have a collision whereas it is typically a shadow. This happens when going under bridges or overpasses, or depending on the glare from the sun. This has happened several times on the highway causing multiple near collisions at high speeds. This is extremely dangerous and requires an adjustment or recall. I have had this part stolen and replaced through a Honda approved repair shop yet the issue persists.
Hi, to whom it may concern my dashboard lights have been on for months now and I’ve taken it to the dealership I purchased my car from and it comes back that it’s the turbo that needs replacing. The pricing of that is ridiculous and I’m currently not the ONLY one with this issue ! It’s an ALL AROUND THE WORLD thing! I’m not sure about anybody else but I don’t have that type of money plus while paying other important bills ! There should be a recall against the turbo replacement as well! And just what if I was to get the turbo replacement and then the lights come back on, because I’ve seen multiple people saying the replacement didn’t help with the lights and still have gotten other things done and the lights only off for a couple days ! Indeed of answers because this is ridiculous!
The car will have all lights on dashboard showing, car has been taken multiple times to dealership and nothing seems to be wrong but this cause all safety features to malfunction. I have talked with other Honda owners, on forums and acquaintances and they have similar issues.
These also are warning signals that keep coming on I took it to AutoZone obd scanner said is was misfire cylinder2got spark plug changed and engine coil still showing same thing on scanner
The problem I am having with my vehicle Honda accord 2018 is with the head gasket. I was on the highway and as I was driving suddenly all the signs came on the display and gave a warning that my vehicle is overheating and it came down to 20mph while I was on the highway. This was very risky to me and the other vehicle around me.
After having fuel pump replaced by recall at random times dashboard will light up with all system lights, car will go into limp mode and loose power for a few seconds and then I am able to resume driving. Extremely scary as there is no warning. This has happened both on the freeway at high rates of speed and on neighborhood roadways. Safety has been compromised several times and Honda dealer is not able to reproduce the issue, retrieve any warning codes or offer any assistance. This has randomly been occurring for several months. When not having this exact issue car runs with no other issues.
The warning lights for many areas has come on without warning. The car runs and drives fine. Took it to Honda. They want between 500 - 2500 to resolve the issue and replace the front radar. This appears to be a consistent problem for these 2018 Hondas. I already had to have the fuel injectors replaced at 48k miles. Another common Honda problem. Please help us as consumers
Vehicle will sometimes automatically emergency brake with nothing in front of it
The issue first appeared during my initial test drive before purchase in 2019. The salesman stated it was a low-battery issue from the car sitting on the lot. Since then, the same problem has recurred multiple times. The vehicle displays multiple warning lights — “Electric Powertrain Fault,” Check Engine, EPS, and VSA — with reduced power, jerky acceleration, and temporary loss of throttle response. This poses a safety risk when merging or crossing intersections. Vehicle: 2018 Honda Accord Sport 1.5T, approximately 52,000 miles. Diagnostic codes retrieved include U0401-68 (ECM/Electric Powertrain Communication Failure), U0416-68 (VSA/EPS System Malfunction), and P0302 (Cylinder #2 Misfire). These faults have occurred despite replacement of spark plugs, ignition coils, and fuel injectors (all OEM Honda parts). Dealerships have not been able to permanently correct the issue. The problem appears related to the ECM or communication network between the powertrain and stability systems. The sudden loss of power and unpredictable throttle response during normal driving creates a serious safety hazard.
When it is cold outside my ACC light comes on and when I started my car the other day it read Emissons Service Problem Avoid Heavy Acceleration and High Speed. That was just 1 among 7 other service warning that popped up.
I was driving on a four-lane highway using adaptive cruise control, gaining on a vehicle ahead. When the cruise control picked up the vehicle, I accelerated slightly, used left turn signal and began changing lanes, the warning for collision mitigation came on and the cruise control disengaged. Continued driving home and the warning continued, and cruise control would not function. Next time used the car the warning light was off, and system functioned properly.

My car be braking and nothing be in front of me.It detects something in front of me when nothing be there.
UNKNOWN. I will be driving and automatically it will lock the brakes and nobody will be in front of me. I tried turning it off but somehow it still ends up on. This has been doing it now for some but it’s getting worse and worse. Before it would just blink on the dash “ BRAKE” but wouldn’t apply the brakes but recently it has been applying the brakes and going from 45mph to 60mph it has done it and giving bad whiplash. Now it’s starting to scare me because someone is going to end up rear - ending me and cause an accident. I tried talking to a dealership about it but they said they will look into it and never hear anything about it. I really am starting to be worried Everytime I drive my car that something bad is going to happen. This needs to be fixed and diagnosed
If car is idling for over 1 minute, all lights on dash come on. When all lights on, car wont wont go over mph, car will randomly sputter in highway when going over 1rpm and will stall randomly. Reported on reddit by multiple people and when I went in to get it diagnosed it was the fuel injector issue
On August 7, 2025, the automatic braking system alerted with the sign break and then proceeded to stop the car when there was no object or vehicle in front of me. This would have been extremely dangerous. If there was someone behind me this is not the first time this has occurred it has happened several times.
Fuel pump recall. Put in an order with Honda dealer January 2024 for the pump. On February 2025 asked if they submitted the order back in January 2024? They said it was. Now it's August 2025 (20 months since) and waiting. the federal safety agency says if they failed to fix in a timely manner to make a report online. Is 20 months long enough? Driving with a safety recall. Second making a complaint with the 10 speed auto transmission 2nd to 3rd hard shift and 4th to 3rd hard shift. Putting stress on other components can break mounts, the transmission, axles, ect. could also launch the car into the car in front of you, in heavy (slow bumper to bumper) traffic. Wasted my own money and time draining and filling 5 quarts of honda 2.0 transmission fluid. (Also replaced the trans filter behind the warmer housing) Did not fix the issue. Contacted American Honda and they said It's out of warranty and I need to pay for diagnostic and repairs. (I just bought the car in 2023 at 45k miles. Previous owner must of felt it and should of did something while under warranty.) Honda know this issue from the beginning and hiding the issue to save money. Check the Accord forums online. It's most of us if not all the 18-20 10 speed models. Vehicle is 2018 Accord 2.0 10 speed 50k miles. Plus the normal Phantom braking and lane departure which will automatically steer you off the road, so you have to fight the steering wheel.
Head Gasket Blown on a 2018 Honda Accord 1.5 Turbo. Yes, yes warning lights have appeared.
Honda Accord 1.5 TURBO, Head Gasket Blown for the second time in 2 years. The problem has been reproduce by dealer and independent service center. The car shakes when you turn on the car, first indication. Then all warning lights show up on dash board.Emission system Problem, Brake system, Vehicle instability, Adapative cruise control, road departue.
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.
All lights on head dash are on , all components are not working properly or effected because of this. (Engine light brake light abs light tire light traction control light , sensors out all) while driving vechile reduces power does not operate randomly , have to pull over shut the car off and turn it back on. Has high vibrations lot of shaking, stauling. I have had it looked at with multiple shops and dealer . Everybody is playing a guessing game and can not pin point what exactly it is . Was told it was spark plugs and coils, alternator , fuel injectors. ALL have been repaired, and still have all lights on dash and still facing every problem listed after repairs. Been inspected by manufacturer. Say not been resolved was told if it wasn’t what was already fixed they don’t know and that this is very common right now . It first started about a month ago.
Emergency Braking System engaged for no apparent reason with no other vehicles on the road. Potential for rear-end collision. This was the first event. Personally inspected forward looking sensors / camera for blockage, none found. Did not notice any messages or warning during the event. Wasn't looking at the dash during the event.
I was behind another vehicle with the adaptive cruise control on and been following the for some distance at a speed below the cruise control setting. Warning came on for the braking mitigation, cruise control disengaged, vehicle began coasting but did not brake. I continued home driving without any other changes, but warning stayed on. After arriving turned vehicle off and restarted, Warning did not come back on. I have not driven vehicle since. I checked and found other reports of similar problems and am filing this report. Will continue driving with extra caution and report any other occurrences.
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.
Well to start I had to replace my head gasket already last winter at 59K miles and for awhile now I had warning lights on my dash for CMBS system failure and cruise control/steering wheel controls don’t work besides the ones for music. No lane assist, none of those safety features work at all and haven’t for awhile
Unknown
Car goes in limp mode once the brake system lights come on. When the brake light system comes on, none of the functions for the automatic breaks or electrical portion of my vehicle works. The car will act as if it will not accelerate right before the codes start to appear on the car.
