Across the 2011–2019 complaint record for the model line, the 2018 model lands near the quiet end, logging just five owner complaints—most frequently in the visibility category—and two recalls, against a 2012 peak of 394 complaints and a 2011 low of one. That makes the 2018 500 one of the more stable years in the model's 2011–2019 run.

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 30,000 mi; coolant every 10,000 mi. The big-interval services (every 10,000 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 2018 Fiat 500 shows a continuation of the downward complaint trend seen after the 2012 peak, with only five complaints filed that year compared with 13 in 2017 and zero in 2019. Recalls remained steady at two per year from 2017 through 2019, while investigations rose to two in 2018 and stayed at that level in 2019, marking a slight increase from the single investigation recorded each year from 2012‑2017. Technical service bulletins also declined, falling from 101 in 2017 to 90 in 2018 and further to 83 in 2019. Overall, the federal record indicates improving reliability metrics for the 2018 model relative to its immediate predecessors and a stable recall posture. Consequently, the 2018 Fiat 500 appears to be a favorable year to purchase, provided any outstanding recalls are verified as completed.
