2017 Alfa Romeo 4C

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2017 4C.

Body PASSENGER CARTransmission Automatic (AM6)

The 2017 Alfa Romeo 4C is a passenger car built on the 4C platform, featuring an Automatic (AM6) transmission and achieving EPA fuel economy ratings of 24 mpg city, 34 mpg highway, and 28 mpg combined, making it a relatively efficient option in its class for the model year. This iteration of the 4C arrived with minimal documented reliability concerns, as reflected by just one total owner complaint filed and zero recalls issued by the manufacturer. The single complaint recorded centered on the engine category, though the absence of any recall activity suggests that widespread mechanical issues were not present. For researchers evaluating vehicle dependability, the 2017 model year represents one of the more problem-free entries in the 4C's production run, with the lack of safety recalls and low complaint volume indicating reasonable baseline reliability.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 2,000 mi; spark plugs every 36,000 mi; coolant at 150,000 mi. The big-interval services (at 150,000 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 Alfa Romeo 4C dominate in one area — the engine, 1 of 1 reports (100%), well ahead of the next concern. NHTSA has issued no recalls for this vehicle, so these are owner-reported concerns only. 0 of the reports describe a crash and 1 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.
