2017 Hyundai Tucson FCEV

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2017 Tucson FCEV.

Body SUV

The 2017 Hyundai Tucson FCEV is a hydrogen fuel cell electric SUV built on Hyundai's global crossover platform, featuring a fuel cell stack that generates electricity from hydrogen to power an electric motor—a powertrain requiring the same 5W-30 API viscosity oil at a 4.7-quart capacity for its internal components. This model year represents a pivotal iteration in Hyundai's FCEV development, though it carries a notable reliability record with 1,074 owner complaints filed, the majority centering on engine-related concerns, alongside three safety recalls issued during its production cycle, suggesting that while the technology represents Hyundai's hydrogen ambitions, this particular model year experienced challenges that prospective researchers should consider when evaluating its long-term viability within the Tucson lineup's evolution.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter at 3,000 mi; coolant every 30,000 mi. The big-interval services (every 30,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

Owner complaints about the 2017 Hyundai Tucson FCEV dominate in one area — the engine, 400 of 1,074 reports (37%), well ahead of the next concern. That matters, because the engine are also the target of recall 21V-727 on this vehicle — so the single most useful check before buying or servicing one is confirming it was actually performed. 13 of the reports describe a crash and 26 a fire — a small share of the total, but worth weighing against the engine pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
