Computer BCM module malfunction while driving. All warning light went off like Christmas tree.

I am submitting a serious safety complaint regarding the placement and design of the electronic parking brake switch in my Honda Accord. The parking brake switch is located on the center console, directly in an area where a driver's hand naturally rests while driving. This creates an unnecessary risk of accidentally activating the parking brake. With a traditional gear selector, shifting into reverse requires two deliberate actions: pressing a release button and physically moving the shifter. These safeguards help prevent accidental operation. However, in the Honda Accord, the parking brake switch can be activated with a simple finger movement. A driver resting their hand on the center console could unintentionally operate this switch. Even if the vehicle has electronic safeguards, accidental activation while driving could cause unexpected braking, startle the driver, or create a dangerous situation. What makes this particularly concerning is that Honda uses a different placement in the Honda Odyssey, positioning the parking brake switch away from where a driver's hand naturally rests. This demonstrates that a safer, less exposed location is possible. The parking brake is not a control that drivers need to access continuously while driving. There is no justification for positioning it where a driver's hand naturally rests. This risk is especially concerning during highway driving, when an unexpected braking event or even a momentary distraction could have serious consequences

Noticed that the engine temperature was slightly higher normal (went to 5 bars when always at 4) I checked and the fan was running properly and had coolant in the overflow tank. I took it to the Honda dealer, and they found that the head gasket failed and the fluid inside the radiator leaked into the cylinders. My 2018 Honda has the 2.0T engine with 126,875 miles. Honda acknowledges this design flaw on their 1.5T and 2.0 non-turbo engines but wouldn't cover my 2.0T. This 2.0T from my research is about 80-100 units of the 1,115,384 accords sold in the US 2018-2022 10th gen. The 2.0T has the same design flaw as the other two engines but Honda wont cover them. Moreover, I asked for 50% good will coverage from Honda and was flat out told no after waiting for 4 weeks to get this decision on a known mechanical engine flaw that could be a safety issue, Eg. fire or loss of power on a highway that can get someone hurt or killed.

The CVT automatic transmission is leaking fluid from the transmission input shaft seal. The leak was diagnosed by Pohanka Honda of Fredericksburg, Virginia in October 2026 at approximately 99,400 miles. The dealer recommended replacing the transmission input shaft seal, a repair that requires removing the transmission, estimated at $2,990.90 plus tax. American Honda reviewed the case (Case #[XXX]) and declined goodwill assistance on [XXX]. The repair has not yet been performed. Safety concern: continued loss of transmission fluid can cause transmission failure and a loss of motive power while driving. No crash, fire, or injuries occurred. The problem is ongoing.

SUPPLEMENTAL DATA FOR ACTIVE ODI CASE #XXX. P1: SYSTEMIC SAFETY RECALL FALSIFICATION (NHTSA 23V-858) This submission supplements active ODI Case #XXX against Honda of Manhasset (Facility #XXX). On XXX, the facility certified Fuel Pump Safety Recall 23V-858 as fully completed to claim warranty credits. Vehicle dashcam recordings irrefutably prove the technician never opened the hood, never disconnected the 12V battery (mandatory safety step to release fuel pressure), and never stood in front of the car. When confronted on XXX with video evidence, advisor [XXX] manually altered the invoice to "Not Performed", falsely blaming a system error/lack of stock, despite parts records proving the recall kit arrived XXX. System admin then issued a corrective invoice "Reprint #1" stating "RECALL NOT PERFORM. PART NOT IN STOCK", dynamic-reopening the VIN nationally to evade corporate detection. This constitutes severe corporate fraud. P2: COMPRESSED ADAS SOFTWARE TOLERANCES AND PROCEDURAL OMISSION The secondary fraud involves an unneeded quote of $1,237.19 and illegal $233.55 diagnostic fee under false pretense of a "bent radar bracket". Independent engineering audit disproved hardware failure, establishing true 0.00° baseline. Technical root cause of DTC P2583-76 was the recall update, migrating the car from the factory 2018 software layout—which possessed a permissive vertical threshold up to ±3.0°—directly to hyper-strict Program ID: 36802-TVA-A190, restricting the window to an unyieldi

My 2018 Honda Accord EX-L with the 2.0L turbocharged engine (K20C4) and 10-speed automatic has had a cylinder head gasket failure at approximately 111,000 miles. The vehicle has been maintained consistently. Starting in early October 2026, the vehicle began shaking violently under acceleration while the engine was cold, including when accelerating at highway speed and climbing hills. The shaking lasted for roughly the first 15 minutes of every drive. No check engine light or diagnostic trouble codes appeared. In mid-October 2026, a Honda dealership diagnosed coolant leaking past the cylinder head gasket into the combustion chamber and quoted approximately $5,000 for the repair. Replacement parts are on backorder with no estimated arrival date. Violent shaking during highway acceleration is a safety concern, and continued coolant leakage into the cylinders can cause further engine damage. In August 2026, American Honda extended head gasket warranty coverage to 10 years or 150,000 miles on 2018–2022 Accord 1.5T and hybrid models for the same condition: coolant entering the combustion chamber and causing misfires. The 2.0L turbo engine was excluded. A pending class action (Alcantara et al. v. American Honda, consolidated with Bissell v. American Honda, S.D. Cal.) alleges head gasket failure in Honda's 1.5L and 2.0L turbocharged engines. I ask that NHTSA investigate head gasket failures in 2018–2022 Accords with the 2.0L turbo engine, and whether this engine should be included in

This has happened several times, usually on interstates, about once every few months. It usually takes place where there is a transition in the road, especially if there is a large shadow combined with a car in front of me. The two places that come to mind include merging on, especially during sunrise or sunset (if the highway is set into the ground like in [XXX]), or when passing under a bridge on the highway, esp with a car in front of me that is slowing down. The latter happened earlier this week, I believe on XXX eastbound in [XXX], passing under the XXX or one of the other streets similar to it.

I contacted Community Honda in Lafayette, La regarding this recall and repair over 2 years ago and it has not been repaired. I was told the part was on back order and have received no communication since

The car hesitates upon acceleration and when it “misses” enough it will flash the engine on the dashboard, and not allow any further acceleration, going into “limp mode”. All the safety controls error on the message center and dashboard warnings all come on, even though it’s only the acceleration/transmission that’s affected. Not sure if it’s fuel injectors or a computer issue, but it’s absolutely dangerous upon entering a highway and hoping to not have system failures, that result in limp mode. I’ve been carrying a 10 mm socket for disconnecting the battery and rebooting the system, when needed. It only helps for a short while.

The car was rough upon idle one day and all the lights came on and systems went down I was bout to drive to a place where the code was read that’s when I first discovered this was a known issue which this model. Head gaket

Reporting fraudulent safety recall compliance & hazardous repair by Honda of Manhasset (Invoice #317524). 1. Recall 23V-858 (Fuel Pump): Dealership registered recall as completed & Service Manager verbally insisted it was done. However, my vehicle's continuous dashcam footage proves fuel pump replacement was NEVER performed. Faced with video evidence, the advisor admitted work wasn't done because the part was out of stock, claiming a "billing error." Invoice reprint says "RECALL NOT PERFORMED, PART NOT IN STOCK" yet they initially processed it, leaving an immediate engine stall risk. 2. Software Campaign & Radar Failure (Service Bulletin 21-068): Dealership performed mandatory Honda Sensing update for Millimeter Wave Radar, wiping old calibration parameters. Per Bulletin 21-068 (Pg 3), the repair is NOT complete until the radar is re-calibrated & the warning light disappears. Instead of performing the radar aiming, the technician left safety systems locked with DTC P2583-76. I authorized a $215 diagnostic fee, but despite having the scanner connected during the update, the technician failed to follow Honda's official troubleshooting protocol to resolve the code and finish the calibration, returning the vehicle with disabled emergency braking features. 3. False Physical Diagnosis: Staff verbally claimed the radar bracket was "bent" to blame a prior impact. Challenged for physical proof, they admitted performing NO physical inspection, stating they "assumed" it was bent solely

In May of 2024, We got a recall letter for an inoperable fuel pump from Honda Automobile Division, & we did not get a replacement. They were short on supply, & those who experienced symptoms as engine light and may have rough engine starts were the priorities. We didn’t get a follow up after 60 days when we received the letter. Now my 2018 Accord has an engine light on, and the car starts up roughly.

The contact owns a 2018 Honda Accord. The contact stated that on several occasions at start-up several unknown warning lights remained illuminated. The dealer cleared the warning lights and the contact stated that during the failure the safety features disengaged. The vehicle was taken to the dealer on several occasions to be diagnosed and the contact was informed that the failure was not duplicated, and the warning lights were cleared. However, shortly after leaving the dealer the warning lights illuminated. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 80,000.

2018 Honda Accord repeated battery drain/electrical failure My 2018 Honda Accord has a recurring electrical problem. The vehicle’s battery is approximately one year old, but it has died six times within the last four weeks. Each time, the battery becomes completely discharged when the vehicle is parked and not driven for several days. A battery test dated XXX, reported: “BAD & REPLACE,” battery health 16%, state of charge 0%, voltage 4.61 V, and measured capacity 106 CCA compared with a rated capacity of 600 CCA. The repeated failures suggest a possible parasitic electrical drain or electronic module that does not shut down when the vehicle is parked. This condition can leave the vehicle stranded and may prevent starting in an unsafe location or emergency. I request that NHTSA investigate whether this is a recurring safety defect affecting 2018 Honda Accords VIN [XXX] Millage 143,000 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The car ACC turns orange, you can’t control your speed, the car starts to slow down like it’s losing power. I got a new battery. Still will cut off during drive and you can’t accelerate. This could cause a major accident. I was turning into a parking lot and lost power. Had to cut the engine off, and hurry up and restart it just to get out the way.

Dashboard lights are coming on for all systems...sometimes they go off but then come back on 2/3 days later. The lights and messages are: collison mitigation braking problem, road departure mitigation system problem, emission system problems avoid heavy acceleration and high speed, tire pressure monitoring system problem, brake system problem brake performance may be reduced, electric power steering system problems steering assist reduced , vehicle stability assist system problem, reduced traction and handling. Concerned about my safety.

Formal Complaint Regarding Repeated Warning Lights and $2,600 Turbocharger Repair Recommendation – 2018 Honda Accord Dear Honda Customer Service / Dealership Management, I am writing to formally express my concern and frustration regarding ongoing issues with my 2018 Honda Accord and the diagnosis and repair recommendation I have received from the dealership. My vehicle has been experiencing an intermittent problem where multiple warning lights and/or error indicators on the dashboard come on at the same time. The problem does not remain consistently active. The warning lights may stay on for several days, then disappear, and later return again. This has happened multiple times. Because the issue is intermittent, I have attempted to have the vehicle properly diagnosed rather than simply replacing parts based on a temporary warning or error code. I have also had a diagnostic scanner connected to the vehicle. At various times, the scanner has not shown an active problem or has not provided a clear explanation that would justify replacing a major and expensive component. Despite the intermittent nature of the problem, I have now been advised that I may need to spend approximately $2,600 to replace the turbocharger due to an underboost condition. I have serious concerns about this recommendation. First, I want to understand exactly how the dealership determined that the turbocharger itself has failed and that replacing the turbocharger will actually resolve the underlying problem

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.

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.

The contact owns a 2018 Honda Accord. The contact stated that while operating the vehicle, the message "SRS Fault" was displayed. The vehicle was taken to the local mechanic to be diagnosed, and it was determined that the passenger’s seat occupant detection sensor had failed and needed to be replaced. Additionally, the mechanic retrieved a seat belt fault code. No further information was available. The vehicle was not yet repaired. The local dealer was notified of the failures and informed the contact that the VIN was not included in NHTSA Campaign Number: 26V332000 (AIR BAGS) nor 23V158000 (SEAT BELT). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 72,000.

This is a known issue with honda. the head gasket is blown causing all the warning lights to come up on the dash. my car has not got hot, it goes up to the H but goes right back down to normal setting. i have had my local honda dealer look at my vehicle and that is what they told me was the issue. since my car has a rebuilt title, honda won't cover the cost for the repair. i bought the car last year from an out of state small dealer with a rebuilt title. honda is being sued for this issue, because they know about it and still were making the vehicles. this is no fault of my own and honda should honor the recall and repair my car at no cost to me. as i am now unable to drive the car and i can't afford to have it repaired. i contacted honda of america and filed a claim and also a good-will request, but because of the rebuilt title, i was not eligible for help. every single honda made during these specific years 2018-2021 are having the same issues. not one car should be discriminated against because of a rebuilt title. the re-build has zero impact on the head gasket and the cylinders being too close together, and the turbo causing the head to blow. my car is right at 128,000 miles, and it’s known for the issue to start occurring around 120,000 miles. then come to also find out there’s an ongoing issue with gas leaking into the oil. they denied my request on that too. any help would be greatly appreciated! thank you for your time and consideration! -RF-

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.

Side airbag not working properly ("SRS problem" intermittently showing up on dashboard): DTC checked and found B0020-13: Open or increased resistance in the left side airbag inflator. No accident on this side of the vehicle has occurred to my knowledge. A few months ago back in March my car was impacted on the right rear tire/quarter panel (repaired at caliber collision). That's the only known accident. The SRS notification first appeared 2 weeks ago and then it turned off. It appeared again yesterday 9/14/2026.

My car starting shutting off on me suddenly while driving. No warning lights. Eventually had it towed to honda. Honda informed me it was the head gasket that blew with only 109,000 miles on the car at the time. My car had the 1.5 turbo engine that is now currently under investigation for this same issue. Ended up having a used motor put in it that cost me $4,000

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 hav

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.

Since I purchased this car in 2022, the collision mitigation braking system has randomly engaged for no reason. This has happened multiple times over the years, day and night, when no other vehicle, road obstructions, or other factors warrant the system triggering.

Unknown of actual issue. Experiencing persistent hard excessive jerking when accelerating. Extended warranty was placed for most Hondas due to head gasket issue but not for 2.0T

The contact's sister-in-law owns a 2018 Honda Accord. The contact stated that while driving the vehicle, the vehicle stalled with several warning lights illuminated. The driver pulled over to the side of the road, and the vehicle failed to restart immediately. The vehicle was restarted after a while. The driver continued driving, but the failure reoccurred. The vehicle was taken to a dealer, where it was diagnosed and determined that the cylinder head gasket, gasket kit, and coolant needed to be replaced. The failure mileage was approximately 132,000.

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.

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.

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.

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

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.

The contact owns a 2018 Honda Accord. The contact stated that while driving at an undisclosed speed, the AC evaporator became inoperable and was blowing hot air. The contact stated that the failure had been occurring since the vehicle was purchased in 2018. The contact stated that the evaporator was leaking. The dealer confirmed the failure. The manufacturer was notified of the failure. The vehicle was not repaired.

There is a hole in the engine block and it happed while I was driving, people could’ve been hurt on the road because of this mechanical failure. Vehicle has only been inspected by a private mechanic who found the problem. There was no warning of this besides a add air to tire warning.

On August 29th 2026 at 1:28PM (13:28) 148,320 mi. on odometer During interstate driving and topping the Sunshine Skyway Bridge on Interstate 275 Northbound (27.617863, -82.653639) the vehicle detected both road departure and engaged the emergency automated braking due to the shadow generated by the superstructure of the Skyway Bridge falling on the road surface. The vehicle attempted to correct the "road departure" by steering the vehicle away from the perceived problem and violently engaged the brakes nearly causing a collision as it has done numerous times before. In this particular event, it was an extraordinarily dangerous situation given the location that it occurred (190ft in the air on a walled in 2 lane interstate highway). I have reported this to NHTSA and American Honda on multiple previous occasions and await a repair or even an acknowledgement of this extremely dangerous issue. Honda has opened a case on this but have had 12+ months and no response has been issued.

I purchased my 2018 Honda Accord Sport from CarMax on January 16, 2026, and I have had several serious problems with the vehicle since purchasing it. Every warning light on the dashboard has come on, my radar system will not stay calibrated, and I have been told that my fuel injectors need to be replaced. In addition, the relay module was already broken when I received the vehicle, which causes the interior lights in my car not to work properly. These issues have caused serious concerns about my safety and the safety of others because I cannot depend on the vehicle’s safety systems or know when another component may fail. The vehicle and affected components are available for inspection upon request. I have attempted to get these problems addressed, but I have not been able to get a satisfactory resolution. The issues have been identified/diagnosed, and I am seeking further inspection to determine the full extent of the problems. I have not had the vehicle inspected by the police or an insurance representative, but I am trying to get the manufacturer/dealer involved so these issues can be properly documented and addressed. I am especially concerned because I have only had this vehicle since January 16, 2026, and I have already put a significant amount of money into it while still owing a substantial amount on the loan. I was also informed that the vehicle could potentially be considered a total loss within the next couple of months. I do not believe it is reasonable for me to

In September 2025, all dashboard lights came on while driving down the road. I immediately pulled over and turned the car off. When turning the car back on, all lights remained on and I drove to the nearest repair shop, where at this time it was beginning to run hot. I was told at this point that the head gasket had blown and this would need to be replaced. I replaced the head gasket for $4100.00. After that, in October 2025, I had to replace the fuel injectors and coil packs. In February 2026, driving down the road, the car was not running hot but all lights came on the dash again and it went into limp mode. The car had to be towed to a repair shop where it was stated that coil packs needed to be changed again. In August 2026, the turbo had to be replaced, resulting in an additional $2500.00

The contact owns a 2018 Honda Accord. The contact stated that while driving at an undisclosed speed, several unknown warning lights were illuminated, and the vehicle went into LIMP Mode, and the vehicle failed to exceed 5 MPH with the accelerator pedal depressed. The vehicle was taken to a dealer where it was diagnosed and determined that the turbo boost and head gasket needed to be replaced. The vehicle was repaired; however, the failure persisted. The failure had occurred on several occasions. The vehicle was towed to an independent mechanic where it was diagnosed and determined that the engine needed to be replaced. The manufacturer was notified of the failure. The failure mileage was approximately 100,000.

I am reporting a suspected head gasket/engine defect involving my 2018 Honda Accord Sport. My vehicle experienced multiple engine-related problems before ultimately requiring head gasket replacement and cylinder head repair. On July 27, 2024, at approximately 161,480 miles, the turbocharger was replaced. In September 2025, at 207,539 miles, my vehicle was serviced at Joe Morgan Honda, an authorized Honda dealership. During that visit, the Honda technician documented that the cooling system fluid level was low and that no external leaks were found. The technician documented that they suspected the head gasket was causing internal coolant loss over time. I was instructed to monitor the vehicle and was provided an estimate of approximately $4,400 plus tax for head gasket replacement. I specifically asked the Honda service advisor whether the head gasket could be repaired at that time or whether anything could be done to prevent the suspected problem from progressing. I was told there was nothing that could be done at that point other than monitor the vehicle. Within weeks, multiple warning lights illuminated on my dashboard and the vehicle began experiencing significant drivability problems, including hesitation, misfiring, and loss of acceleration. The loss of acceleration was particularly concerning because the vehicle did not respond or accelerate normally while being driven. I took the vehicle to Integrity Automotive on September 25, 2025, at 208,583 miles. The engine was ch

Issue 1: Faulty Collision Mitigation Braking System & Subsequent Crash Incident Details: In July of 2025, my vehicle’s automatic braking warning lights randomly activated and triggered an unprompted, emergency stop on [XXX]—despite having no vehicles ahead of me. This sudden malfunction directly caused a rear-end collision on the interstate. Documentation: A formal crash report was filed with the Georgia State Patrol. Ongoing Risk: The false automatic braking warnings continue to trigger randomly, creating an extreme safety hazard for myself and surrounding traffic. Issue 2: Premature Turbocharger Failure & Cracked Head Gasket Diagnostic Timeline: Immediately upon picking up the car from a body shop repair, every warning light on the dashboard illuminated erratically. After Ed Voyles Honda in Marietta claimed nothing was wrong, the body shop replaced a potentially loose battery cable. The issue persisted, and Shottenkirk Honda in Cartersville ultimately diagnosed a total turbocharger failure in March 2026. Out-of-Pocket Cost: Honda denied any goodwill coverage despite the widespread, documented failure of these 1.5L engines across 2018–2023 models. I paid $1,700 out of pocket to replace the turbocharger. Escalating Failures: Shortly after the turbo replacement, the head gasket cover cracked—another notorious, widely recognized defect inherent to this specific engine setup. At only seven years old, this vehicle has proven to be unreliable, dangerous, and financially burdensome

Turbo has gone out and it's several thousand dollars to get fixed and will eventually affect the overall lifespan and performance of the engine if not repaired in a timely enough fashion. There is no recall for this specific issues even though thousands of Honda Accord owners are dealing with the same failure/repair and there are no offers of goodwill assistance from the dealership or manufacturer. The dealership assured that engine failure is inevitable without a turbo replacement and they can't determine the extent of the damage that's already been done to the engine since the turbo showed signs of failure.
