2018 Chrysler 300 — 6.4L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 300 6.4L.

Body PASSENGER CAREngine 6.4LTransmission Automatic 8-spd

The 2018 Chrysler 300 is a full-size passenger car built on Chrysler's LX platform, powered by a 6.4L V8 mated to an 8-speed automatic transmission that returns EPA figures of 19 city, 30 highway, and 23 combined mpg. Routine maintenance calls for 6.0 quarts of 5W-20 engine oil, and the vehicle's 152 total owner complaints—concentrated mainly in the electrical system—along with four recalls place it firmly in the lower tier of the model's complaint history, which spans 2004 through 2023. For context, the worst year on record is 2006 with 1,750 complaints, while the best is 2004 with just two, meaning the 2018 sits far closer to the quiet end of that spectrum. That relative calm suggests Chrysler had largely sorted the platform's longstanding issues by this stage, making the 2018 a more mature entry in the 300's lineage.

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; 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 Chrysler 300's federal record shows a dramatic improvement from its early-generation peak of 1,750 complaints in 2006, settling into a mature phase with significantly lower volumes by 2015. However, the 2018 model year represents an anomaly in this downward trend, as complaints nearly doubled from 82 in 2017 to 152, accompanied by an increase from two to four recalls. The data does not specify the root causes, but 2018 complaints are heavily concentrated in the Electrical System (41 standalone, 12 combined with "Unknown or Other"), alongside 10 air bag complaints and 6 crash-related incidents. Compared to the subsequent 2019 model year—which saw complaints plummet to just 60—the 2018 figures suggest a step backward in component reliability for that specific production run. Given the uncharacteristic spike in electrical complaints and recalls relative to the smoother 2017 and 2019 model years, the 2018 Chrysler 300 is not the optimal choice, and you should prioritize a 2019 model for a more reliable late-generation purchase.
