My 2023 Honda Odyssey, VIN 5fnrl6h78pb005459, has developed an unusually loud noise from the engine compartment when I press the accelerator. The vehicle was purchased in August 2022 and currently has approximately 78,800 miles. An independent mechanic inspected the vehicle and did not identify an internal engine problem. The mechanic suspects that the high-pressure fuel pump may be the source of the abnormal noise, but this has not yet been confirmed by a Honda dealership. I am concerned that the noise could indicate a developing fuel-system defect and would like this issue documented and reviewed for any potential safety implications. I request that NHTSA investigate whether similar reports involving the 2023 Honda Odyssey indicate a defect that may warrant a safety recall.
While driving, the vehicle loses power, hesitates, and jerks, then stalls and shuts off without warning, especially in extreme heat and stop-and-go traffic. The failure occurs more frequently when the fuel level drops below approximately half a tank. After stalling, the vehicle will not restart until it cools down for 20–30 minutes, then temporarily operates normally before the issue repeats. Warning symptoms prior to failure include loss of acceleration, hesitation, and engine overheating. A fuel pump–related fault code has been detected. The vehicle has stalled while driving, creating a serious safety risk due to sudden loss of power in traffic. This condition matches NHTSA recall 23v858000, which states the fuel pump may fail and cause engine stall while driving. The fuel system component believed to be involved is available for inspection upon request. The issue has occurred multiple times and is reproducible under similar conditions.
