INDEPENDENT EVIDENCE TYPES

NHTSA owner complaint records remain part of Official Vehicle Data. Subjective review contributions remain in Owner Experience. One does not validate or prove the other. Read the methodology.

EVIDENCE, NOT A SCORE

WHAT THIS DATA CAN TELL YOU ABOUT RELIABILITY

Official records can provide useful research context, but each source has a different meaning. Complaint counts are not failure rates; recalls are formal safety campaigns; manufacturer communications are technical or service documentation; and investigations reflect formal NHTSA activity. Data Confidence measures evidence availability, not vehicle quality. CarIQ does not publish a composite Reliability Score.

Available evidence summary: 1,878 NHTSA owner complaint records; 6 safety recall campaigns; 300 manufacturer communications; 2 applicable NHTSA defect investigations.

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 have photographs of the diagnostic scans documenting the codes and records showing the previous repair.

On February 21, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation (PE22003) to assess reports of inadvertent activation of the Collision Mitigation Braking System (CMBS), an automatic emergency braking (AEB) system, in model year 2017-2019 Honda CR-V and 2018-2019 Honda Accord vehicles. The reports allege that activation of the AEB system occurs while driving with no apparent obstruction in the vehicle's forward path, resulting in sudden vehicle deceleration. Honda indicated that they were aware of a total of X,XXX reports that may relate to the alleged defect. Honda provided analysis of the alleged defect and alleges that some customers possibly had an inadequate understanding of the CMBS and its limitations. However, many consumer complaints allege that Honda dealerships were unable to reproduce the condition or state that they were informed that this is considered normal CMBS operation. To date, ODI has received a total of 1,294 consumer complaints of inadvertent activation of CMBS in 2017-2022 Honda CR-V and 2018-2022 Honda Accord vehicles. A total of 31 complaints alleged a crash and 50 alleged an injury. The Total column in the Failure Report Summary removes duplicate reports and shows the total number of reports with unique VINs from all Manufacturer, ODI, and EWR data sources. In some cases, there were multiple reports associated with a particular vehicle in which recurring failures were alleged. In total, there were X,XXX reports, 93 injury incidents and 47 crashes involving vehicles with unique VINs that may relate to the alleged defect. PE22-003 has been upgraded to an Engineering Analysis to further assess the scope, frequency, and potential safety related consequences of the inadvertent AEB activations. The scope has been expanded to include assessment of model year 2020-2022 Honda CR-V and Accord vehicles.

On February 21, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation (PE22003) to assess reports of inadvertent activation of the Collision Mitigation Braking System (CMBS), an automatic emergency braking (AEB) system, in model year 2017-2019 Honda CR-V and 2018-2019 Honda Accord vehicles. The reports allege that activation of the AEB system occurs while driving with no apparent obstruction in the vehicle's forward path, resulting in sudden vehicle deceleration. Honda indicated that they were aware of a total of X,XXX reports that may relate to the alleged defect. Honda provided analysis of the alleged defect and alleges that some customers possibly had an inadequate understanding of the CMBS and its limitations. However, many consumer complaints allege that Honda dealerships were unable to reproduce the condition or state that they were informed that this is considered normal CMBS operation. To date, ODI has received a total of 1,081 consumer complaints of inadvertent activation of CMBS in the subject vehicles. A total of 24 complaints alleged a crash and 42 alleged an injury. The Total column in the Failure Report Summary removes duplicate reports and shows the total number of reports with unique VINs from all Manufacturer, ODI, and EWR data sources. In some cases, there were multiple reports associated with a particular vehicle in which recurring failures were alleged. In total, there were X,XXX reports, 84 injury incidents and 40 crashes involving vehicles with unique VINs that may relate to the alleged defect. PE22003 has been upgraded to an Engineering Analysis (EA24002) to further assess the scope, frequency, and potential safety related consequences of the inadvertent AEB activations. Further the scope has been expanded to include assessment of model year 2020-2022 Honda CR-V and Accord vehicles. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

NHTSA investigations evaluate potential motor-vehicle safety defects. The existence of an investigation does not by itself establish that a safety defect exists, and the absence of an investigation does not establish that a vehicle is problem-free.

Open and closed describe NHTSA's process status, not a CarIQ reliability judgment.

DESCRIPTIVE SOURCE OVERLAP

CROSS-SOURCE VEHICLE DATA

CarIQ compares categories appearing across independent NHTSA datasets. Overlap can help identify areas with more available documentation, but it does not establish defect frequency or prove that an individual vehicle will experience a problem.
