Fuel system issue
FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY
Acura (American Honda Motor Co.) is recalling certain 2014-2019 Acura ILX vehicles. The vehicles may have a deformed fuel tank, raising the height of the fuel pump and allowing the fuel level float to stick, possibly causing the fuel gauge to display an inaccurate fuel level.

How this compares
At 29 MPG combined, the 2018 Acura ILX ranks 8th of 18 compact cars EPA rated for 2018 — 0.5 MPG better than the 28.5 MPG median for that group.
That places it squarely mid-pack for its class. Fuel cost is close enough to its rivals that other running costs will probably matter more.
EPA puts annual fuel spend at about $2,600, $350 more than the $2,250 typical for the class. Over five years at 15,000 miles a year that is roughly $13,000, a $1,750 difference against a class-median vehicle.
Tailpipe CO₂ is 309 grams per mile — about 4.6 metric tons over 15,000 miles of driving.
