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 every 60,000 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 model year represents a significant improvement over the preceding 2013, with complaints dropping sharply from 41 to 16 and recalls decreasing from three to one, while technical service bulletins also fell from 383 to 283. Positioned after the generation’s peak complaint volume in 2013 and establishing a stable baseline that continues into 2015—with nearly identical complaint counts of 16 and 15 respectively—the 2014 model sits in a normalized mid-generation window rather than the declining volume seen in 2016-2019. Federal data shows zero investigations for 2014, and the top complaint areas are evenly distributed with only two reports each for steering, seats, fuel/propulsion, and electrical systems, indicating no concentrated systemic defect in the dataset. Although crash-related complaints number five, fire complaints register at zero, and the single recall places 2014 favorably against the three recalls of 2013 and the two recalls of both 2018 and 2019. Given its substantial reduction in reported problems compared to the 2013 peak and its stable positioning within the generation’s reliability arc, the 2014 GS350 presents a sound acquisition target for used car buyers.
