FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY24/01/2019

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.

Risk: If the fuel gauge displays that the vehicle has more gas than it actually does, the vehicle may run out of gas and stall, increasing the risk of a crash.

Fix: Acura will notify owners, and dealers will inspect and, as necessary, replace the fuel tank, free of charge. The recall began March 14, 2019. Owners may contact Acura customer service at 1-888-234-2138. Acura's number for this recall is H3U, Z3T.
