Fuel System issues make up roughly 2% of all Acura owner complaints. The majority of the issues have been reported by MDX owners.
The complaint we hear about most often is engine light on in the 2012 MDX.
Sometimes it helps just to tally up the complaints and see where the biggest stacks are. Use this information to learn about troublespots or to run for the hills.
The fuel pump suppliers say the propellers can crack and deform, partly because they absorb too much fuel and also because of the solvent drying process used during manufacturing. Once deformed, the impellers can disable the pumps and cause a sudden shut down of the engine. The recall is expected to begin at the end of July 2020.
A lawsuit alleges that the 2016-2020 MDX and RDX continue to randomly lose engine power, nearly a year after a possibly related fuel pump recall. And proving it to a mechanic is nearly impossible as the power almost always comes back on and the vehicle acts like nothing ever happened.
Acura is part of a recall for over 437,000 vehicles to prevent the engine from suddenly shutting down due to a clogged fuel pump. Sodium particulates, often found in cheap gas, can cling to the inside of the pump and increase resistance as they heat up.
