2014 Scion iQ

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2014 iQ.

Transmission Automatic (variable gear ratios)

The 2014 Scion iQ pairs an automatic transmission with variable gear ratios to deliver an EPA-rated 36/37/37 mpg, with its minimal mechanical packaging reflected right down to a 3.7-quart oil capacity requiring 0W-20 or 5W-20 API viscosity. Although the iQ's top complaint areas historically encompass the power train, vehicle speed control, and service brakes, the 2014 model logged only a single owner complaint alongside zero recalls. Sitting at the absolute lowest complaint volume across the 20122015 generation, this model year stands as the high-water mark for reliability in the iQ's brief history.

Service quick specs OEM factory data

Capacities, torques and tune-up values from the factory service manual.

This engine holds 3.7 qt of 5W-20 / 0W-20 API engine oil. Torque lug nuts to 76 ft-lbs, the oil drain plug to 18.0 ft-lbs. The firing order is 1-3-4-2. Note the cylinder-head bolts finish on a torque angle (torque-to-yield) — they stretch permanently and should be replaced, not reused, during any head service.

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; spark plugs at 120,000 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.

The 2014 Scion iQ sits at the quietest point in the model’s federal record, with just one complaint, zero recalls, and no investigations, a sharp decline from the 17 complaints and one recall recorded in 2012 and the five complaints and one recall in 2013. Technical Service Bulletins also retreated from a generational high of 114 in 2013 to 95 in 2014 before falling further to 59 in 2015, positioning the target year in a mature, stabilized phase of the production run. The sole 2014 complaint is categorized under Power Train, Vehicle Speed Control, and Service Brakes, and although the data notes one crash-related complaint, it does not specify a root cause. Given that both complaints and recalls reached their lowest levels of the generation after dropping steadily since launch, the 2014 model offers the cleanest federal profile of the range and is a sound choice for a used-car buyer.
