2018 Toyota C

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 C.

Body PASSENGER CARTransmission Automatic (AV-S7)

The 2018 Toyota C is a passenger car built on the HR platform, pairing an Automatic (AV-S7) transmission with an engine that requires 4.4 quarts of 0W-20 oil to deliver an EPA-estimated 27 city, 31 highway, and 29 combined mpg. Beneath these straightforward mechanical specifications, however, lies a more complicated reliability picture defined by 295 total owner complaints and a single recall. Because the Power Train represents the top complaint area for this specific model year, the 2018 C sits at a compromised point in the vehicle's reliability history, meaning researchers must weigh powertrain concerns heavily when evaluating this iteration.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 10,000 mi; coolant every 50,000 mi. The big-interval services (every 50,000 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 2018 Toyota C dominate in one area — the power train, 175 of 295 reports (59%), well ahead of the next concern. None of this vehicle's 1 recall campaigns target the power train, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 9 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the power train 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.
