What 83 owners told NHTSA about the 2017 Mazda Mazda3 Sedan

Anytime the tank was filled with gas there was a strong smell of gasoline vapors that persisted for several days. The car was a few months past its warranty on emissions issues and so I was charged about $1500 to replace a cracked fuel pump and fuel vent that was stuck open. The mechanic also said that the check engine light should have warned me about the problem but that neither the dashboard light nor his diagnostic equipment was triggered by the defect. He suspects the car's computer is programmed to avoid drawing attention to the problem. Had the light been working I would likely have caught the problem while it was still under warranty.

My 2017 Mazda 3 (85,000 miles) suddenly had the engine light go on and a loss of power. I’m lucky I didn’t have an accident. I took it immediately to the shop and they informed me that my low pressure fuel pump is bad. I see they have a recall on Mazda 2018–2020 fuel pumps. However, I also saw a class action lawsuit attempt to include Mazdas from previous years because the fuel pump has the same number as those cars. I had just taken my car in for routine maintenance, spark plug change, and inspection at the dealership two weeks before this incidence happened and they didn’t report anything wrong with my car.
