2021 Ford Transit-350

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2021 Transit.

Transmission Automatic (S6)

The 2021 Ford Transit rides on the 350 platform with an automatic (S6) transmission, and its engine service calls for 6.0 quarts of 5W-30, 0W-30, or 5W-20 oil. EPA estimates rate it at 20/27/22 mpg. Within the model’s 2001–2026 complaint spectrum—running from a low of one grievance in 2001 to a peak of 188 in 2015—this model year generated just 23 owner complaints and four recalls, with power-train issues leading the count, placing it among the lower-complaint entries in the Transit's reliability history.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs every 100,000 mi; coolant at 200,000 mi. The big-interval services (at 200,000 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.

The 2021 Ford Transit represents a mid-cycle year for its generation, with federal data showing a notable decline in complaints and recalls compared to the peak years of 2015–2017, when issues spiked sharply (e.g., 188 complaints and 26 recalls in 2015). By 2021, complaints dropped to 82—still elevated relative to pre-2015 levels but a clear improvement from the earlier surge—while recalls fell to 9, aligning with the downward trend observed since 2018. The top complaint areas (Power Train, Wheels, Electrical System) mirror persistent themes across the generation, though the 2021 figures suggest incremental refinements rather than systemic overhauls. Crash-related complaints (2) and no fire reports further indicate relative stability, though the data doesn’t specify root causes for these issues. Positioned between the 2020 and unproven 2026 models, the 2021 sits in a pragmatic sweet spot: post-peak reliability but pre-redesign uncertainty. **Takeaway: The 2021 Transit is a sound used buy, offering improved dependability over earlier model years without the risk of first-year redesign quirks.**
