   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.

   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)

   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. An “underboost” condition or related diagnostic code does not necessarily, by itself, establish that the turbocharger is defective. There can potentially be other causes of an underboost condition, including issues involving boost-control components, hoses, connections, sensors, vacuum or pressure leaks, wiring, electronic controls, or other related components.

   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.

    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

    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.

    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.

    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.

    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.

    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.
