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. A safety-critical control should require deliberate activation and should not be susceptible to incidental contact. I strongly urge Honda and federal safety regulators to investigate this design, evaluate the risk of accidental activation, and consider relocating the switch or implementing additional safeguards. This is an unnecessary and preventable safety hazard that should be addressed before someone is injured.

SUPPLEMENTAL DATA FOR ACTIVE ODI CASE #XXX. P1: SYSTEMIC SAFETY RECALL FALSIFICATION (the federal safety agency 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 unyielding 0.0°±0.1°. Due to suspension settling over 259,258 km, the radar had a natural deviation of -2.25°, which A190 flagged, disabling ACC. On XXX, the Shop Foreman confessed technicians willfully skip physical radar re-centering protocols because they "take too much time". After manual adjustment back to 0.00°, a 19km road test dynamically cleared DTC [XXX] per Honda Bulletin 21-068. Subpoena dealer records for ID A190.

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.

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 because the scanner showed P2583-76. This is a blatant lie to cover up their failure to follow factory troubleshooting workflow for this specific DTC, which dictates aiming the radar, not fabricating physical damage to justify leaving the safety repair incomplete.

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.

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 the federal safety agency, it showed 0 unrepaired recalls. I am submitting this complaint so that the federal safety agency 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.

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.

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 the federal safety agency 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.

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 the federal safety agency 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.
