Acura MDX fuel system problems, 2016–2026
170 of the 1,605 complaints owners filed with NHTSA about the Acura MDX 2016–2026 name the fuel system (NHTSA’s “Fuel/Propulsion System” heading — fuel tanks, lines, pumps and injection — and on an EV, the propulsion battery and motors). The loudest years: 2018 (51), 2019 (46), 2016 (31). Filed under the same heading across these years: 3 manufacturer bulletins, 6 recall campaigns. Every figure is a linked federal record; none is a failure rate, none a repair cost, and none a verdict on one car.

Two things the counts carry that are not the car: how many of each year were sold, and how long each has been on the road — an older year out-counts a newer one before anything is wrong with it. The share column is the honest comparison across years: what part of that year’s complaints named the fuel system. Nothing here is a rate.
When the fuel system complaints were filed, and at what mileage
Source: NHTSA complaint databaseFiled per calendar year, every model year together: 2015: 1 · 2016: 1 · 2017: 2 · 2018: 4 · 2019: 4 · 2020: 6 · 2021: 10 · 2022: 7 · 2023: 11 · 2024: 77 · 2025: 25 · 2026: 22
Across the model years, half of the 48 owners who gave an odometer reading reported the fuel system problem between 17,000 and 70,000 miles. A median of reports, not the life of a part.

Common questions
Source: NHTSA complaint database, recalls and manufacturer communicationsWhich Acura MDX years have the most fuel system complaints?
2018, 51; 2019, 46; 2016, 31. Raw counts, and an older year has had longer to collect them; by share of each year's own complaints the loudest is the 2018 (30%).
Is there a recall for the fuel system on the Acura MDX?
Yes — 6 campaigns are filed under this heading across these model years: 25V031000 (2025), 23V858000 (2020), 21V215000 (2020), 19V060000 (2018). A recall is matched by VIN, and applies to specific years; check yours at nhtsa.gov/recalls.
When do fuel system problems show up on the Acura MDX?
Owners who gave an odometer reading reported it at a median of 50,000 miles across the model years; half of them between 17,000 and 70,000. That is when reports cluster, not the life of a part.
What does NHTSA's "Fuel/Propulsion System" heading cover?
Fuel tanks, lines, pumps and injection — and on an EV, the propulsion battery and motors. Owners choose the heading when they file, so it says which area of the vehicle the complaint is about, not which part failed.
