What is the most strongly supported recurring defect for the 2019–2026 Honda Odyssey?
The best-documented issue is a Denso fuel pump impeller failure affecting 2019–2020 Honda Odyssey models under NHTSA recall 21V351000. The impeller can swell, causing the fuel pump to seize, which may lead to the engine cranking without starting or stalling without warning while driving. A sudden loss of engine power increases the risk of a crash, especially in traffic. The recall remedy is a free dealer replacement of the fuel pump module, so owners do not pay for this repair.
