Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 Challenger 6.4L. Covers both the standard and High Output 6.4L.
The 2018 Dodge Challenger 6.4L is a passenger car built on the LA platform, powered by a 6.4-liter engine paired with an automatic 8-speed transmission, and it requires 6.0 quarts of 5W-20 oil per service. Its EPA fuel economy of 15 city, 25 highway, and 18 combined mpg reflects the balance expected from a large-displacement V8 in a two-door coupe. Within the model’s complaint history spanning 2008 to 2023, the 2018 model year recorded 74 total owner complaints—a figure that sits well below the peak of 298 complaints logged for the 2010 model, though it still places this year among those with moderate owner feedback, alongside four recalls that researchers should note when assessing long-term dependability.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The Challenger generation shows a clear downward trend in federal complaints from early highs—peaking at 298 in 2010 and remaining elevated through 2012—toward far lower volumes in the mid- to late-2010s. The 2018 model sits in this later low-complaint arc, posting 74 complaints, four recalls, and one investigation, which represents a modest increase from 2017’s 49 complaints and three recalls but remains well below the generation’s peak activity. Technical service bulletins for 2018 totaled 254, up from 194 in 2017 though below 2019’s 314, while the top complaint categories were “Unknown Or Other” and “Electrical System” at 14 reports each; the data does not specify root causes for these. Crash and fire complaints for the year totaled nine and two, respectively, with 2019 subsequently dropping to 57 complaints and three recalls. Because 2018 falls within the generation’s matured, lower-volume phase rather than its troubled early years, it presents as a comparatively favorable used purchase, contingent on confirmation that all four recalls have been completed.
All 74 complaints on record, top 8 components.
