general problems of the 2018 Honda Accord - part 1

The contact owns a 2018 Honda Accord. The contact stated that while starting the vehicle, several unknown warning lights unexpectedly illuminated on the instrument panel. The failure mileage was approximately 116,242.

Vehicle dashboard lights up with multiple warnings, power loss/limp mode in traffic and while driving. Dealership said it’s a very common problem but Honda refuses to make a recall. Technician says it is most likely caused by faulty fuel pump which is already recall that caused damage to the injectors.

While driving on a bridge at under 20 mph, the vehicle's head gasket failed, causing the engine to overheat and coolant to leak from within the engine. The vehicle threw diagnostic trouble code p2601 and immediately entered "limp mode," severely cutting engine power and vehicle speed. Because this happened on a bridge with no shoulder to safely pull over, the sudden loss of power created a serious safety hazard — the vehicle could not maintain a safe speed or keep pace with surrounding traffic, increasing the risk of being struck by other vehicles. The vehicle was taken to a tampa Honda (11000 n florida Ave), where the failure was confirmed to be a blown head gasket that allowed coolant to leak into the engine cylinders. The head gasket and related components were replaced at a cost of approximately $5,000 to restore the vehicle to safe operating condition. The failed component is no longer available for inspection in its failed state, as replacement was required to make the vehicle drivable. No dealer, manufacturer representative, police officer, or insurance adjuster has inspected the vehicle; only at tampa Honda facility that performed the repair diagnosed and confirmed the head gasket failure. Prior to this incident, no warning lamps or symptoms were noted — the p2601 code and limp mode activation occurred simultaneously with the sudden overheating and coolant loss, with no advance warning. This failure is consistent with a widely reported defect pattern among Honda vehicles with similar engines, where the head gasket fails prematurely and allows coolant to enter the cylinders. Honda has not issued a recall or acknowledged a manufacturing defect despite numerous consumer reports describing the same failure mode.

The contact owns a 2018 Honda Accord. The contact stated that after stopping the vehicle, the check engine, stabili-trak, steering, and the forward collision avoidance warning lights were illuminated, with unknown messages displayed. The vehicle was taken to the local dealer, and a system reset was performed, and the contact was informed that the battery needed to be replaced. The contact stated that the battery was recently replaced. The contact retrieved the vehicle, and hours later the failure reoccurred. The cause of the failure was not yet determined, and the vehicle was not yet repaired. The manufacturer was not yet contacted. The failure mileage was 127,000.

While driving, the vehicle suddenly jerks or “jumps,” followed immediately by a noticeable loss of power. Shortly after this occurs, the multi-information display shows a series of warnings that include: collision mitigation braking system problem – see your dealer adaptive cruise control system problem – see your dealer road departure mitigation system problem – see your dealer auto high-beam problem – manual controls available – see your dealer brake system warning light a “systems initializing… continue driving” message also appears. I have photographic documentation of these dashboard messages. This sequence creates a significant safety concern. The sudden jerk and power loss can occur while the vehicle is in motion, and the subsequent disabling of the Honda sensing systems (collision mitigation braking, adaptive cruise control, and road departure mitigation) leaves the vehicle without those critical driver-assistance features. Because this involves sudden power loss and the disabling of safety systems, I consider the issue urgent and ask that it be prioritized.

While driving, my vehicle began shaking/rough running and the check-engine light came on. Multiple warning lights and system warnings appeared on the dashboard, including the brake system, steering, traction control, and tpms warnings. The vehicle experienced noticeable shaking and reduced/abnormal performance. I am concerned that this may be a safety-related defect because multiple vehicle systems are being affected.

2 weeks ago. All of my warnings and lights for my car came on. We undid my battery, charged it and did it again. The lights went away and about 3 days ago they came back on. Now my car is overheating and the system is reading wrong.

In the duration of ownership with this vehicle, there is always lights lighting up on the dashboard which trigger my sensors and causes my dashboard to light up like a christmas tree. I do not feel safe when that happens randomly in the middle of driving on the highway.

I bought this car used and I've only had it two months and the head gasket has blown. I didn't know the 10th generation had bad gaskets and turbos I found that out after I purchased the car. Literally everyone I know now that had one the gasket or turbo went out. Not only that it was a recall on my fuel pump no one told me about until I added it to my insurance and they told me. Yes Honda dealership fixed it for free now it needs to be a recall on these turbos and head gaskets. It's not fair. I wouldn't recommend Honda to no one now and they say Honda last a lifetime. Thats not true quit making the 10th generation and take it off the market.

It started with multiple lights glowing on my dash. Then progressively the car felt sluggish and ultimately while driving to church in July the car cut off while I was making a turn. Some kind gentleman pushed my car helping me get out the intersection.

Vehicle brought to ocean Honda, weymouth MA with complaint that hvac system underperforming. Customer asked to replace condensor under warrany but Honda required full diagnostic ($135). Honda disclosed that 2/3 hvac system had leaks, and known issues. Honda has a known issue with faulty and leaking ac condensers, heat exchange pipes, and evaporators. They reported this vehicle had leaking condensor and heat exchange pipe. Honda stated they can replace the the condenser under warranty, but not the heat exchange pipe or evaporators - even though they admit both are faulty and often require repair, replacement, and costly ac system recharge. The costly repairs (upwards of $1,800-$2,000+) are passed onto the customer. These failures are confirmed by dealer (ocean Honda - weymouth) and considered hazardous, but refusal to fix unless cost is absorbed by customer.

At approximately 159,000 miles, my vehicle exhibited multiple dashboard warning lights simultaneously including abs, vsa, eps, tpms, brake, acc, cmbs, and rdm warnings along with engine misfire codes. Borescope inspection confirmed coolant intrusion into cylinder 1. Cylinders 2, 3, and 4 were dry. Diagnosis confirmed head gasket failure consistent with the known design defect in the 1. 5l turbocharged I-vtec engine related to inadequate head bolt clamping force versus boost pressure. This failure is the subject of active class action litigation (bissell v. American Honda motor CO. , case 3:24-cv-02286-ajb-mmp). Vehicle requires full head gasket replacement at my own expense estimated at $900+. No recall has been issued despite widespread reports of identical failures across 2018-2022 Honda Accord 1. 5t vehicles.

My car keeps losing power suddenly! sometimes it has even started to stall while driving. Also the electrical menu has tons of errors and isn't working. There are several recalls on Honda Accords for the fuel pump and the vehicle assistance module but my VIN doesn't show up.

There are 13 alerts showing on the instrument panel for various systems not functioning, along with accompanying yellow dash lights such as tire pressure, abs, brake system, traction control, acc, and lkas. Systems not available include, abs system, adaptive cruise control, road departure mitigation, auto high-beam, tpms, electric power steering, plus several others. These alerts first started January 2026 and occasionally would disappear; however, over the past few months the warnings have become constant. The vehicle has approx. 120,000 miles. Due to tpms not functioning, I am not given a warning when a tire has gone flat/blown while driving as the tire pressure light is always on the dash. The only warning I am provided is the sound/smell of the rim dragging along the road to notify me the tire is flat. This poses a risk to myself and others by creating an emergent situation requiring me to pull over rapidly. Another incident occurred when acc was enabled (at a time when the alerts had been appearing on and off). Cruise control set at 70 mph when suddenly the above mentioned alerts reappeared and acc system became unavailable, leading to unexpected deceleration on the highway. This poses a risk to myself and others as it creates unpredictable driving patterns, unbeknownst to the driver. Initially I replaced the battery with no resolution of the issue. I later discovered maintenance code displayed by the vehicle was c003a-62 for right rear wheel speed sensor circuit failure (circuit short to ground or open). The mechanic recommended replacing the right wheel hub assembly as this was suspected to be the cause of failed circuit. When that repair lasted no more than 10 mins before the warnings reappeared, the right rear wheel speed sensor itself was then replaced. Similarly, this did not fix the issue. I have not sought additional service due to repair costs beginning to add up with no resolution. Based on the history of reports, this issue does not seem uncommon.

The contact owns a 2018 Honda Accord. The contact stated that while driving approximately 40 mph, the air bag warning light illuminated, and the message "srs fault - see dealer" was displayed. The vehicle was taken to a dealer where it was diagnosed and determined that rodent had eaten through the wiring and that the wiring insulation was soy-based, and the air bag cable and the harness cable needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 68,000.

Ac compressor problem.

Everytime upon start up I get a message saying supplement restraint system error see dealer, should not be having this issue.

While 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 multiple times and await a repair of this dangerous issue. Honda has opened a case on this but have had 18 months and no response has been issued.

The head gaskets and turbo supercharger goes out at a certain amount of miles.

The day I purchased the vehicle from the dealer, every warning light began cycling on including the automatic emergency braking failure, engine system failure and others. I immediately took the car back to the dealer and they supposedly repaired it. When the car was returned to me, I drove it for less than a week and the same thing happened again. When the light came on, the car’s auto braking and cruise control stopped working. I took it back to the dealer and they said it was the head gaskets, which they fixed. When I got the car back again, I drove it for 2 days and it did the same thing again, this time all of the warning codes came on. This time, I had a total engine failure because the timing chain broke. The dealer took almost two months to replace the engine and it cost us almost $6,000. I got the car back last Saturday. Today, driving home from work, the automatic brake system failure warning came on again and the car won’t automatically brake and cruise control wouldn’t work. This is exactly what happened last time. I am afraid to drive this car because I don’t know if the brakes will fail and the system currently isn’t working. We are taking it back to the dealer which will likely cost us more money. We are stuck with this car and cannot get rid of it because we owe more money on it then it is worth because of replacing the engine.

Car keeps throwing cylinder 2 misfire, replaced all spark plugs, fuel indicators and still having issues. Think it’s the ecm/pcm is bad or there’s a bad connection.

Car went into limp mode and was struggling to accelerate, went and got it diagnosed and was notified that my spark plugs needed to be replaced. Car began running fine but a few months went by and the issue came back. I was told I needed my spark plugs changed again. After the third time, I went and had my car diagnosed again and was told I needed a battery for the car because it was drained. Then I got the turbo replaced and still the issue remains. All lights on the dashboard are on, car overheats and goes into limp mode, sometimes not accelerating over 20 mph. My car went into limp mode on the highway, this scared me, so I haven't drove it since. Ive seen countless comments of users with the same make and model, experiencing the same issue. Its sad that Honda, known to be a trustworthy and reliable brand for years would do their customers like this, especially considering the state of the economy at the moment.

Infotainment center continually freezes. When it does, backup camera does not work. I have tried software updates but it has gotten worse. It is also very slow to reboot so again, no backup camera during that time.

The dashboard on the vehicle lights up with multiple error notifications. This puts the vehicle in limp mode. Indicates emissions errors, check engine, lane mitigation, brakes, control system. Per different customers this fault is being caused by either faulty fuel injector, miss fire, bad ignition coils, damage head gaskets, or turbo mechanism faulty. My vehicle has 70,000 miles and others in the chat have less miles that are having similar problems. Head gaskets should not fail so soon with proper maintenance. My obd2 scan code is miss fire which could indicate faulty spark plugs, coil, injector or headgasket. For a vehicle at 70,000 miles this shouldn't happen. Vehicle has been maintained as the manufacturer recommendations.

I have bought this car new in 2018, the issue that I’m having is that . . I’ll be driving on the highway or local my car will brake on its own without any hazards in front of it . It’s very dangerous it almost caused me an accident on the highway .

A supplemental restraint warning came on dashboard, I noticed other Accord owners are experiencing the same this light has to do with possibly airbags or seatbelts making it possibly unsafe to drive.

All warning lights are on the dash. Came on while driving.

Doors lock actuators problem the break so fast , fuel injector problem head gasket, break warning sistem problems.

A 2018 Honda Accord suddenly displayed multiple dashboard warning messages at the same time after previously operating normally. The warnings include: emission system problem (avoid heavy acceleration), tire pressure monitoring system (tpms) problem, brake system problem, brake hold system problem, electric power steering system problem, vehicle stability assist problem, hill start assist problem, adaptive cruise control system problem, collision mitigation braking system problem, and road departure mitigation system problem. These alerts appeared simultaneously when the vehicle was started, even though the car had been driven the night before without any issues. The vehicle still starts and runs, but the number of system warnings suggests a possible electrical, sensor, or control module issue affecting multiple vehicle systems.

1>engine failure: around the time vehicle reached 148,000 miles on it, it blew a head gasket on cylinder 2. Coolant was in the cylinders. The vehicle would not accelerate and was misfiring. 2> safety was affected as this occured on interstate 40 and caused the vehicle to slow to an unsafe speed. 3>problem was confirmed by morganton Honda- morganton nc. 4> check engine light.

Turbo and the head gasket.

Head gasket caused multiple issues with coolant burning quickly. Multiple ignition coils also got damaged and had to be replaced. Though the underlying issue with the gasket was not addressed by the dealership. The head gasket is currently broken and does not function at all and the car has only driven 84000 miles.

The high-pressure fuel pump on my 2018 Honda Accord failed even though the vehicle had previously been repaired under a recall for the same issue. While driving, multiple warning lights illuminated on the dashboard, including the check engine light and other system warnings. The vehicle began running rough and lost power, creating a dangerous driving condition, especially in traffic. This is the second occurrence of fuel system failure despite the recall repair being completed. The recurrence of this issue raises serious safety concerns, as sudden power loss or engine malfunction while driving increases the risk of an accident. The vehicle is currently not safe to drive due to the risk of stalling or loss of power. The problem appears to be related to the high-pressure fuel pump system that was previously addressed under recall.

What component or system failed or malfunctioned, and is it available for inspection upon request? I own a 2018 Honda Accord with approximately 132,000 miles. Shortly after my vehicle was serviced for the fuel pump recall, multiple warning lights and system failure messages appeared simultaneously. The affected systems include road departure mitigation, emission system, adaptive cruise control, auto high beam, collision mitigation braking system, electric power steering, vehicle stability assist, tire pressure monitoring system, hill start assist, and the air bag system. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? the failure of multiple safety and driver-assistance systems has created a significant safety risk. My vehicle is currently operating in limp mode, resulting in reduced performance and making it difficult to drive safely in traffic. The loss or malfunction of systems such as collision mitigation braking, power steering, vehicle stability assist, adaptive cruise control, and air bag monitoring increases the risk of an accident and could jeopardize the safety of both vehicle occupants and other motorists. Has the problem been reproduced or confirmed by a dealer or independent service center? yes. I took the vehicle to a Honda dealership for diagnostic testing after the warning lights appeared. The dealer confirmed that multiple systems were reporting faults. I was advised that numerous components would need to be replaced at a substantial cost. Prior to the fuel pump recall service, I had not experienced any of these issues and the vehicle operated normally. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? the vehicle has been inspected by a Honda dealership for diagnostic purposes. To my knowledge, it has not been inspected by Honda corporate, law enforcement, or insurance representatives. Were there any warning lamps, mes.

Everytime I try to turn my wheel it’ll get stiff and the notification will pop up saying “electric power steering system” but then it’ll go back to normal and when I start the car it sounds like it doesn’t want to start at all and like the cords are trying to connect because they start making a ticking sound. I’ve had issues with electrical before to where the airbags and lane assist had to be fixed but the issues seems to keep circling back around. Something going on with the electrical in the car and I have only had it for about a year and a half.
