NHTSA Complaint #11704371 — 2025 HONDA ODYSSEY

Dear NHTSA, I am submitting a safety complaint regarding my 2025 Honda Odyssey, which has been diagnosed with a transmission failure requiring full replacement due to faulty internal seals. The vehicle is less than one year old, and this type of premature failure raises serious safety concerns. I first became aware that something might be wrong during a routine oil change on November 11, when technicians noticed signs that the transmission might be leaking or malfunctioning. I continued to monitor the vehicle, and on November 28, I was informed that the entire transmission must be replaced due to faulty seals inside the transmission assembly. A critical component like the transmission should not fail this early in the life of the vehicle, and a structural defect such as faulty seals may indicate a manufacturing issue that could affect other vehicles of the same model and year. Information from the dealership: SHEEHY HONDA OF ALEXANDRIA Diagnosed transmission failure caused by faulty seals Recommended repair: Complete transmission replacement Explanation: Premature failure of internal transmission seals leading to fluid loss and unsafe operation Repairs completed so far: Diagnostic inspections confirming failure This vehicle is used to transport children, and a sudden transmission failure presents a significant safety risk. For a new vehicle to require a full transmission replacement within its first year of use is highly concerning. I am requesting that NHTSA review this issue to determine whether other 2025 Honda Odyssey vehicles may also be experiencing similar premature transmission failures. Thank you for your attention to this matter. I can provide repair documentation, inspection notes, photos, or any additional information upon request. Sincerely, Allison Epps 334-464-0233 [email protected] Vehicle: 2025 Honda Odyssey
