2018 Dodge Caravan — 3.6L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 Caravan 3.6L.

Body VANEngine 3.6LTransmission Automatic 6-spd

The 2018 Dodge Caravan is a van on the RT platform, powered by a 3.6L engine paired with a six-speed automatic transmission, delivering an EPA-estimated 20 mpg combined (17 city/25 highway). Its 267 owner complaints, led by electrical system issues and accompanied by four recalls, place it far above the 2017 model year’s low of just one complaint but well below the 1996 peak of 1,647, situating this year in a moderate reliability range within the nameplate’s long history.

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 2018 Dodge Caravan sits just beyond the federal record provided, with the most recent data year being 2017, making a direct year-over-year comparison impossible. However, the trajectory leading into 2018 shows a pronounced quality improvement arc: complaints plummeted from 333 in 1990 to just 2 in 2016 and 1 in 2017, while recalls dropped from peaks of 16 (1996) to zero in 2014–2016 before a single recall in 2017. TSBs similarly contracted from a high of 158 (2014) to 110 by 2017. The 2018 model's top complaint areas—Electrical System (43) and Structure (42)—suggest these remain focal points for owners, though without 2018-specific recall or investigation data, the severity of these issues cannot be assessed against prior years. Notably, 2018 carries 8 crash-related complaints and zero fire complaints, offering some reassurance on safety-critical outcomes. Takeaway: Based on the 2017 baseline and the clear downward trend in complaints and recalls through the late-model years, the 2018 Caravan appears to be a solid candidate, though the absence of 2018 recall data means buyers should independently verify whether any field actions were issued after the dataset's cutoff.
