Body PASSENGER CARTransmission Automatic 4-spd

The 2018 Toyota Yaris is a passenger car fitted with an automatic 4-speed transmission and EPA-rated at 30/35/32 mpg, with routine oil service calling for 3.9 quarts of 5W-30 API oil. Within the model's 2006-2020 complaint history, the 2018 model sits near the bottom of the range, far below the 2007 peak of 296 complaints and close to the 2014 low of 2. That points to a quiet reliability record for this model year, supported by just 4 owner complaints, one recall, and the top reported issue area concentrated in air bags and seat belts.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 5,000 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.

Across the 2006‑2020 span, complaints peaked in 2007 at 296 and then fell sharply, reaching a low of 2 complaints in 2014 before fluctuating in the mid‑teens. Recalls followed a similar pattern, declining from a high of 10 in 2007‑2009 to a low of 1 in 2013‑2014, with occasional rises to 4‑5 in 2012 and 2015 and back to 1 in 2016 and 2018. In 2018 the Yaris recorded 4 complaints and 1 recall, which is below the 2015‑2017 levels and markedly lower than the 2019 figure of 26 complaints and 3 recalls. The 2018 totals also sit near the low end of the post‑2014 range, comparable to the 5 complaints/2 recalls seen in 2016 and well under the early‑generation highs. Given the comparatively low complaint and recall activity for the 2018 model year, it represents a relatively strong choice among used Yaris options.
