I am not sure what component failed. My lights on my dash will not go off. I have done everything I was told to do, ever down to a new battery. & they will not go off. My car will not go over a certain speed. Before this, there were no problems. No warning lights & it was driving perfectly fine. Please help. When I researched this issue, I noticed a million others having the same problem. There has to be a recall on these Honda’s. Let alone, just a simple answer as to why this is happening.

While driving, the car’s engine suddenly shut off, and the brakes were barely responsive, making it extremely difficult to bring the vehicle to a complete stop despite continuously applying the brakes. This was a very serious and frightening safety issue that nearly caused me to crash into another vehicle or an object. I am very concerned about the safety and reliability of this vehicle and believe it needs to be inspected immediately.

I am reporting a recurring safety and mechanical issue with my 2018 Honda Accord 1. 5t, which currently has approximately 128,900 miles. My vehicle has been experiencing shaking/rough operation and multiple warning lights while driving. Diagnostic scans have shown p0301 – cylinder 1 misfire and u0401-68. The ignition coils were replaced with original/oem parts in an attempt to correct the issue. After the repair, the warning lights went away temporarily, but within several days the same warning lights and symptoms returned, and the vehicle again showed the p0301 cylinder 1 misfire code. I am concerned because the vehicle continues to shake and operate abnormally despite the repair. I have learned that Honda has addressed cylinder-head-gasket concerns involving certain 1. 5l turbocharged Accord vehicles, which may cause engine misfires. However, I have not had my vehicle diagnosed with a defective head gasket, so I am not claiming that this is definitely the cause of my vehicle's problem. When I checked my VIN through NHTSA, it showed 0 unrepaired recalls. I am submitting this complaint so that NHTSA has a record of the recurring problem and can determine whether my vehicle's condition may be related to a broader safety defect affecting 2018 Honda Accord 1. 5t vehicles. I am concerned about the possibility of the continued misfire causing loss of engine performance, loss of power, stalling, or otherwise making the vehicle unsafe to operate if the underlying problem worsens. I have photographs of the diagnostic scans documenting the codes and records showing the previous repair.

The contact owns a 2018 Honda Accord. The contact stated that on several occasions while driving, the vehicle lost automotive power with several unknown warning lights illuminated. The vehicle was taken to an independent mechanic where it was diagnosed, and the contact was informed that the head gasket was allowing coolant to leak into the cylinders which caused the vehicle to lose automotive power. The contact was informed that the head gasket needed to be replaced. The manufacturer was not notified of the failure. The failure mileage was 150,000.

Car was overheating while driving. Received warning signs on the dash to pull over and turn car off immediately. Which I did. Very dangerous to do, especially with my three year old on a 90° summer day. I felt fear for my life while waiting on the side of a busy road during rush hour for the engine to cool and figure out what to do. Here the head gasket blew. A defect in the engine that Honda knows about. As a matter of fact, they have lawsuits for this exact occurrence.

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.

This has actually been a problem since I first got the car in 2015 but probably started happening in 2016. But it happens so intermittently that I hardly thought about it or figured it just needed a new battery. But I changed the battery and it is still happening where the car won't start. I have to push the button repeatedly or put the car in n to get it to start. Eventually it works but I'm worried about an electrical issue causing a fire. When it doesn't start all the lights on the dashboard light up. I keep trying and eventually it works. As I said, I'm afraid it will cause a fire. I called Honda and they said some cars were recalled for starter issues but not my VIN number. Seems like if other Hondas had issues mine would too.

Subject: a request for Honda corporate investigation and goodwill assistance - 2021 Honda Accord I am submitting a formal complaint regarding serious and recurring electrical and safety-related problems with my 2021 Honda Accord. 1. Numerous dashboard warning lights and safety-system warnings illuminate simultaneously. 2. The vehicle repeatedly displays messages instructing me to "see dealer. " 3. The power door locks repeatedly click and cycle as though they are attempting to lock or unlock on their own. 4. The stereo, on its own, scrolls through buttons and bluetooth blinking through all the stereo options on its own. 5. An obd diagnostic code reader is unable to properly communicate with the vehicle and reports "unable to connect/vehicle not found. " 6. Sudden brake activated without any object being in front of the vehicle. 7. Factory rims extensive finish failure the simultaneous occurrence of these problems strongly suggest that this may involve an electrical, communication-network, body control module, wiring, power-supply, or other vehicle system defect rather than ordinary wear and tear. I am particularly concerned because the dashboard warnings involve vehicle systems that may affect braking, steering, stability control, driver-assistance features, and other safety functions. When numerous safety warnings illuminate at the same time, I have no reliable way of knowing which vehicle systems are actually functioning correctly. The repeated activation of the door-lock system is also concerning. The locks should not continuously activate on their own during normal vehicle operation. Combined with the diagnostic communication failure and multiple warning messages, this raises concern regarding a larger electrical or vehicle-network malfunction. Although the vehicle is currently outside the factory warranty period, this type of widespread electrical and safety malfunction should not reasonably occur in a 2021 vehicle as the result of normal use.

Head gasket needs replacement - known issue with Honda Accord 2019 1. 5t and open class action lawsuit is in progress.

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 2020 Honda Accord. The contact stated that while driving on several occasions at various speeds, the messages "emissions system failure," "electric power steering failure," "hill start assistant failure," "collision mitigation," "collision road departure," "tpms failure," "brake system failure”, “brake performance reduced", "vehicle stability assistance failure," "adaptive cruise control failure", "road departure mitigation failure," and "brake hold system failure" were displayed. The contact stated that the check engine, tpms, brake system, traction control, and power steering warning lights were illuminated. The vehicle was taken to a dealer where it was diagnosed that the head gasket and turbocharger needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

All the safety dashboard lights are on, what is the problem? I need this situation to be fixed ASAP, it doesnt even let me drive, it loses power and the battery is brand new.

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.

The car was driving fine and then all of the dashboard lights came on. The car wouldn’t drive faster than 20 mph. The dealership said it was a head gasket and injector problem. They quoted me $6000.

The car suddenly stopped speeding up on the highway, and the check engine light began to flash. There were no warning signs before this occurred. I was driving with my kids when I had to think and move quickly off the highway because there were other cars behind us. The car would only roll because it wouldn’t speed up. Yesterday, on August 17, the car was towed to a Honda dealership, where they ran some tests. They found out that the car has a blown head gasket.

Vehicle started sputtering, then all the engine lights came on. The car felt like it did not want to drive. Took it to the dealer for diagnosis. Dealer reported that the head gasket needed to be replaced. He stated that this is a known issue but that Honda has not issued a recall. The car only has $100,000 miles. Dealer said to call american Honda to see if they would give any "good will" money. They declined.

All warning lights came on whilst driving. Scheduled a diagnostic at the dealership. Dealership confirmed the head gasket had blown due to the design flaw of the coolant pathway between cylinder #2 and #3. This is a common problem with this engine. Vehicle is out of warranty. Now faced with a big repair bill.

2019 Honda Accord, the transmission is failing, slipping gears, delayed or harsh shifting, unusual noises, warning lights on, transmission or check engine light illuminate, signaling potential issues, fluid leaks I have a 2019 Honda Accord, the fuel pump failed and the Honda service center in miami charged me $1308. 00 and it was supposed to be a free recall. I need help, the car is falling apart. Thanks.

I own a 2018 Honda Accord sport 2. 0t that has been consistently maintained through authorized Honda dealerships. On July 30, 2026, at 135,968 miles, I took my vehicle to nalley Honda for a blind spot information system warning and maintenance. The dealership performed a multi-point inspection and documented the spark plugs, cooling-system hoses, and fluid leaks as passing. I authorized approximately $1,231 in repairs and maintenance. Only days and approximately 202 miles later, multiple warning lights appeared. I returned to the same dealership. At 136,170 miles, Honda documented dtc p0302 (cylinder #2 misfire). The injectors passed an air-fuel test. The technician then noted pressure releasing from the cooling system despite low coolant temperature. A head-gasket leak test was performed and failed. Honda diagnosed a blown cylinder head gasket and recommended approximately $4,906 in repairs, including spark plugs that had passed inspection only days earlier. I am concerned about the sudden failure of a major engine component in a well-maintained vehicle, particularly so soon after a Honda dealership inspection. I have learned that other Honda Accord 2. 0t owners have reported premature head-gasket failures. A failed head gasket can result in misfires, coolant loss, overheating, reduced engine performance, and potential engine damage while driving. I am requesting that NHTSA review this complaint along with similar complaints involving Honda Accord 2. 0t head-gasket failures to determine whether a defect trend exists and whether an investigation is warranted.

The contact owns a 2021 Honda Accord. The contact stated that while her son was driving 55 mph, the vehicle shut off with several warning lights illuminated on the instrument panel. The contact's son pulled off to the shoulder of the highway and had the vehicle towed to a dealer. While at the dealer, the mechanic discovered coolant leaking into cylinder #2, causing an engine misfire. The dealer replaced the head gasket. After the repair, the failure returned immediately upon driving the vehicle home from the dealer. The vehicle was taken back to the dealer and the failure persisted upon return of the vehicle. While checking the repair order, the contact discovered that the service report was blank. The dealer was unable to duplicate the failure or determine the cause of the issue. The contact was not notified of the issue after retrieving the vehicle. The manufacturer was notified of the failure, and the contact was provided a case number. The vehicle remained with the dealer unrepaired. The failure mileage was 43,881.

I am reporting a safety concern involving my 2018 Honda Accord. I purchased my vehicle used in January 2024 at approximately 90,000 miles and have kept up with the recommended maintenance during my ownership. At approximately 120,000 miles, a Honda dealership diagnosed head-gasket failure with coolant intrusion involving cylinders 3 and 4. Before diagnosis, the vehicle experienced rising engine temperature while idling, coolant loss, jerking during acceleration, numerous warning lights, and severely reduced acceleration. The problem progressed to loss of power and stalling while driving and slowing/stopping, requiring me to place the vehicle in park and restart the engine to continue driving. The vehicle also developed unstable rpms and engine surging while in park. Honda performed a cooling-system pressure test and borescope inspection and confirmed coolant intrusion. Head-gasket replacement cost approximately $5,000. I contacted american Honda (case #16533411), but goodwill assistance was denied because the vehicle is outside warranty and Honda stated it had no Honda-dealership service history. I am reporting this because the head-gasket failure resulted in loss of propulsion and stalling while operating the vehicle, creating a serious safety concern.
