Is there a fix? Manufacturer service bulletins

The failure pattern owners describe
The 2020 Acura RDX fuel system issues center on a single recall campaign (23V858000) that owners say has been stalled by a parts shortage. Out of 16 complaints, 13 are purely about unavailable recall parts—no actual failures—but three owners reported genuine breakdowns.
One owner's fuel pump fractured at 53,000 miles, stopping the engine cold and triggering unknown warning lights. Another stalled without warning at 20 MPH and 58,000 miles, then restarted. A third had hard-start issues around 20,000 miles. All three failures align with recall 23V858000, which targets a fuel system defect.
The pattern is clear: Acura issued the recall notification, but the replacement parts dried up. Dealers told owners the parts were unavailable or no longer available, and some owners reported waiting months beyond what they consider reasonable. One owner was even charged a diagnostic fee despite the unresolved recall. The manufacturer acknowledged some complaints but appears unable or unwilling to expedite parts. Owners remain stuck with broken or potentially broken vehicles and no path to repair.
