NHTSA Investigations

Defect investigations by NHTSA that cover this model year, with what they found.

Engine failures outside the scope of an engine recall
Closed without a recall
NHTSA's recall query tested whether Honda recall 23V-751 was wide enough. That recall covers 3.5-liter V6 engines with a crankshaft defect. The query covered 2018-2020 Odysseys, 2015-2020 Pilots and 2017-2019 Ridgelines. NHTSA found Honda had set the scope properly and closed the query in August 2025. It moved the complaints to PE25-008.
