BACKGROUND
On December 18, 2023, Acura notified NHTSA of its intention to initiate a STOP SALE and safety recall for a certain number of 2018–20 ILX, 2018–20 MDX, 2017–20 NSX, 2018–20 RDX, 2018–20 RLX, and 2018–20 TLX units in order to
replace fuel pump modules manufactured with defective impellers. A defective impeller may cause the fuel pump to become inoperative which could prevent an engine from starting or stall an engine while driving, increasing the risk of a crash.
Affected vehicles may be equipped with a fuel pump module manufactured with low density impellers. The low density impellers may absorb fuel over time and deform. If an impeller deforms to a point that it creates sufficient interference with the fuel pump body, the fuel pump can become inoperative, which may cause the symptoms listed above and/or illumination of the Malfunction Indicator Lamp in the instrument panel.
If this temporary placeholder bulletin appears during an iN VIN status inquiry, the vehicle is subject to a safety recall. Any affected vehicles in your dealer inventory are on STOP SALE until further notice. Refrain from calling Tech Line
for updates.
The following suggested text should be included on any repair order for an already sold affected vehicle that comes in for service. This information should be printed out completely any time service is conducted on an affected vehicle, and the recall repair has not yet been completed. Once parts and repair information are available, the normal procedures under Dealer Operations Manual (DOM) 7.2.1 will apply for this recall.
Suggested verbiage to be included on the repair order:
Client advised that:
The vehicle may be subject to a recall affecting the fuel pump module. The parts necessary to complete the recall repair are not yet available. Once parts repair kits are available, the registered owner of the vehicle will receive a notice to bring the vehicle in for replacement of the components.
Please be advised that clients will still be able to register their vehicles with their respective Department of Motor Vehicles at this time.
For any questions or concerns customers may have, you may have them contact Acura Client Support & Campaign Center at 1-888-234-2138.
This bulletin will be updated once the parts information is available.
