Body PASSENGER CAREngine 6.4LTransmission Automatic 8-spd

The 2015 Dodge Challenger 6.4L is a rear‑wheel‑drive passenger car built on the LA platform and powered by a 6.4‑liter V8 that consumes 7.0 qt of 0W‑40 oil and is mated to an eight‑speed automatic transmission, delivering EPA ratings of 15 mpg city, 25 mpg highway and 18 mpg combined. Its power‑train focus is reflected in the reliability data, where the model recorded 126 owner complaints overall, with the drivetrain identified as the top complaint area and six recalls issued for the year. Within the broader 2008‑2023 Challenger complaint history, 2015 falls between the peak of 298 complaints in 2010 and the low of just nine complaints in 2022, indicating a mid‑cycle position where issues have begun to subside but the power‑train remains the most scrutinized component.

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 2008–2023 Dodge Challenger generation saw owner complaints surge to a peak of 298 in 2010 before generally declining, while technical service bulletins (TSBs) climbed to a maximum of 350 in 2015 and then receded. The 2015 model sits at a clear inflection point: its 126 complaints are lower than the early peak but higher than the following years (78 in 2016, 49 in 2017), and it records the highest TSB volume and the only instance of two federal investigations in the dataset. Recalls stand at 6, above the generation’s later average, with power train (18 complaints) and engine (11) leading reported issues, alongside 16 crash-related and 3 fire-related complaints. The TSB spike implies extensive manufacturer documentation of known concerns, yet the elevated investigations and recall count signal heightened regulatory scrutiny. For a used buyer, a 2016 or 2017 Challenger offers a sharper drop in complaints and recalls, making them a more trouble-free choice.
