American Honda Motor Company's recent issues with fuel pumps continue, as a new recall affects a large number of Honda and Acura vehicles from the 2018-2020 model years. The recall covers a total of 136,057 vehicles, including select 2018-2019 Acura NSX, 2019 Acura RDX, RLX, and RLX Sport Hybrid models, as well as 2018-2019 Honda Accords, Civic Hatchbacks, Civic Type Rs, HR-Vs, 2019-2020 Insights, and 2019 Fits.
National Highway Traffic Safety Administration campaign No. 20V314000, published May 28, 2020, states that the low-pressure fuel pump inside the fuel tanks of the aforementioned vehicles could falter or completely fail. Should the low-pressure fuel pump fail, the car could stall, regardless of its state of motion.
Recall documents reveal fuel pump might fail due to swelling of the fuel pump motor impeller, which would cause the pump to seize. This issue is the result of a problem with how the parts were manufactured. These "lower density impellers" were "exposed to production solvent drying for longer periods of time." This caused some impellers to have surface cracking, which resulted in "excessive fuel absorption," which warps the impellers. Here's a breakdown of how many vehicles of each type were potentially affected:
- 2018-2019 Acura NSX: 146
- 2019 Acura RDX: 34,405
- 2019 RLX: 124
- 2019 RLX Sport Hybrid: 206
- 2018-2019 Honda Accord: 11,227
- 2018-2019 Civic Hatchback: 24,235
- 2018-2019 Civic Type R: 1,785
- 2018-2019 HR-V: 39,676
