WHAT IS THE REASON FOR THIS NOTICE?

Acura has decided that a defect which relates to motor vehicle safety exists in certain 2018 – 2019 model year NSX vehicles that may have a fuel pump module with out of specification impellers. Over time, these impellers may absorb an excessive amount of fuel and deform. A deformed impeller may cause the fuel pump to stop working.

 

SAFETY CONSEQUENCE

An inoperative fuel pump could prevent an engine from starting or cause a vehicle to stall while being driven, increasing the risk of a crash.

 

EMISSION CONSEQUENCE

The check engine light may illuminate as a result of this defect. Your vehicle may fail a state or local emissions inspection when such tests are required under state law if you do not have the repair done.

 

WHAT WILL ACURA DO?

The dealer will replace the fuel pump assembly for free.

 

WHAT SHOULD YOU DO?

Please call any authorized Acura dealer and make an appointment to have your vehicle’s fuel pump assembly replaced for free. Once you make an appointment for your vehicle, be advised that the replacement process may take approximately 9 hours and 30 minutes.
