2014 Jeep Wrangler — 3.6L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2014 Wrangler 3.6L.

Body SUVEngine 3.6LTransmission Automatic 5-spd

The 2014 Jeep Wrangler is a JK-platform SUV powered by a 3.6L engine and a 5-speed automatic transmission, returning an EPA-estimated 17 city, 21 highway, and 18 combined mpg. Maintaining that powertrain requires 6.0 quarts of 5W-20 API oil, a notable detail given that the engine is the top complaint area among the 647 total owner complaints and four recalls logged for this model year. Within the Wrangler’s broader 1990–2023 reliability timeline, the 2014 sits in a middling position—far better than the 1,793-complaint peak of 2018, yet well above the 1996 low of just five complaints, indicating to researchers a year of moderate but significant mechanical scrutiny.

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 2014 Jeep Wrangler sits in the middle of the JK generation (2007–2018), a period that saw complaint and recall numbers spike early (1,255 complaints and 9 recalls in 2008) and again in 2012 (828 complaints, 10 recalls). By 2014, complaints held steady at 647—identical to 2013—but recalls dropped to just 4, the lowest since 2006, and investigations fell to 4 from 6 the prior year. This marks a clear downward trend in recall frequency after the 2010–2012 peak, though the 216 TSBs remain high, indicating ongoing service advisories. The top complaint area is Engine (251), and there are 21 crash and 24 fire complaints, but the data does not specify root causes for these issues. Overall, the 2014 model year appears to be a relatively stable point in the JK arc, with fewer recalls than earlier years, but the persistent complaint volume means a thorough pre-purchase inspection—especially of the engine—is essential. It is a reasonable buy if you prioritize lower recall risk over the very earliest JK years, but not a standout.
