Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2021 Challenger.
The 2021 Dodge Challenger calls for 6.0 quarts of 5W-20 engine oil and has generated 18 owner complaints across two recalls, with air bags standing out as the top reported concern. Within the model’s 2008–2023 complaint history, that 18-complaint total sits just above the range low of nine recorded in 2022 and well beneath the 2010 peak of 298. That placement marks the 2021 model year as one of the more settled entries in the Challenger’s documented reliability record.

Factory maintenance schedule OEM · verified
Normal service, condensed from the factory interval matrix.
Under the factory schedule, replace the engine oil and filter every 6,000 mi; spark plugs every 96,000 mi; coolant at 150,000 mi. The big-interval services (at 150,000 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 2021 Dodge Challenger registers 18 complaints, 2 recalls, 0 investigations, and 286 TSBs, positioning it as one of the cleanest years in the model's modern federal record, second only to 2022's 9 complaints. Compared to the generation's complaint peak of 298 in 2010 and the 126-to-253 range that defined the 2011-2015 era, 2021 represents a dramatically matured vehicle with most early-build issues long since flushed out, while its 2 recalls and 0 investigations further suggest no active federal scrutiny. The elevated TSB count of 286, though still high in absolute terms, is part of a downward arc from the 2015 peak of 350 and 2020's 320, indicating that service-related refinements were tapering as the platform approached its end of run. The top complaint areas — Air Bags (3), Power Train (2), Unknown Or Other (2), and Steering (1) — are spread thinly across categories rather than concentrated in a single defect, and with 4 crash-related and 1 fire-related complaints out of 18 total, the data does not specify a dominant safety failure mode. The 2023 follow-up does see a modest rebound to 40 complaints, so a pre-purchase inspection focused on airbag, powertrain, and steering behavior is still warranted. Overall, 2021 stands as a strong candidate year within this generation, offering the low-complaint, low-recall profile buyers should prioritize.
