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 100,000 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 federal record for the Jeep Wrangler shows significant volatility in complaints, peaking sharply in 2008 and 2018, while recalls and TSBs generally trended upward in later model years. The 2015 model falls within a relatively stable period of the generation, showing a decrease in complaints to 456 from 647 in 2014. This stability continued into 2016, which saw a nearly identical complaint count of 453, though recalls increased from 3 in 2015 to 5 in 2016. In 2015, the primary complaint areas were the engine (79), service brakes (59), and air bags (52), though the data does not specify the root causes for these issues. The year also recorded 15 crash complaints and 27 fire complaints. Given its low recall count and the downward trend in complaints relative to the preceding year, 2015 is a good year to buy.
