Five years of fuel
$14,120–$19,570U.S. average; Ohio $12,620–$17,660 at local prices; every version of this model year; fuel only, not other costs of owning it; 15,000 miles a year, at EIA fuel prices for the week of Oct 12, 2026
NHTSA's VIN data lists these trims for the 2018 300. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 153 complaints with NHTSA about the 2018 300. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 4 recall campaigns for the 2018 300 over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
Chrysler (FCA US, LLC) (Stellantis) is recalling certain 2018-2021 Dodge Charger and Chrysler 300 vehicles. The right and left side curtain air bag inflators may rupture due to a manufacturing defect.
Risk: An inflator rupture may result in sharp metal fragments striking occupants, resulting in injury or death.
Remedy: Dealers will replace both side curtain air bags, free of charge. Owner notification letters were mailed beginning February 20, 2025. Owners may contact FCA US, LLC customer service at 1-800-853-1403. FCA US, LLC's number for this recall is 19B.
Chrysler (FCA US LLC) is recalling certain 2018 Jeep Renegade, Compass and Grand Cherokee, RAM 1500 and Promaster, Fiat 500x, Dodge Journey, Challenger, Charger and Durango and Chrysler 300x vehicles, 2017-2018 Jeep Wrangler, Dodge Grand Caravan and Chrysler Town and Country vehicles and 2018-2019 Jeep Cherokee and 2018 Chrysler Pacifica and Pacifica Hybrid vehicles. The powertrain control module may be equipped with a voltage regulator chip in the circuit board that may fail, causing a stall or a no start condition.
Risk: A vehicle stall can increase the risk of a crash.
Remedy: Chrysler will notify owners, and dealers will replace the powertrain control module, free of charge. The recall began October 2, 2018. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is U87.
Chrysler (FCA US LLC) is recalling certain 2014-2018 Dodge Journey, Charger and Durango, RAM 2500, 3500, 3500 Cab Chassis (more than 10,000lb), 4500 Cab Chassis and 5500 Cab Chassis, Jeep Cherokee and Grand Cherokee and Chrysler 300, 2014-2019 RAM 1500, 2015-2018 Dodge Challenger, 2015-2017 Chrysler 200, 2016-2018 RAM 3500 Cab Chassis (less than 10,000 lb), 2017-2018 Chrysler Pacifica and 2018 Jeep Wrangler vehicles. These vehicles are being recalled to address a defect that could prevent the cruise control system from disengaging. If, when using cruise control, there is a short circuit within the vehicle's wiring, the driver may not be able to shut off the cruise control either by depressing the brake pedal or manually turning the system off once it has been engaged, resulting in either the vehicle maintaining its current speed or possibly accelerating.
Risk: If the vehicle maintains its speed or accelerates despite attempts to deactivate the cruise control, there would be an increased risk of a crash.
Remedy: Chrysler will notify owners, and dealers will inspect the software, and perform a software flash on the engine or powertrain control module, free of charge. The recall began June 4, 2018. Owners may contact Chrysler customer service at 1-800-853-1403. Note: Owners are advised to stop using cruise control until the software update has been performed. In the event that cruise control cannot be disengaged while driving, owners should firmly and steadily apply the brakes and shift the transmission to neutral, placing the vehicle in park once it has stopped.
Chrysler (FCA US LLC) is recalling certain 2018 Dodge Charger, Durango and Challenger, Jeep Grand Cherokee and Wrangler, Chrysler 300, and RAM 1500 vehicles. An incorrect transmission park lock rod may have been installed in the transmission.
Risk: If the incorrect park lock rod is installed, the transmission may not shift into 'PARK' and keep the vehicle from moving, increasing the risk of unintended vehicle movement and the risk of a crash.
Remedy: Chrysler will notify owners, and dealers will install the correct park lock rod, free of charge. The recall began June 28, 2018. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is U43.
