The 300 (2005 to 2023) is Chrysler's rear-drive full-size sedan on the LX and LD platforms. Engines include 2.7-, 3.5- and 3.6-liter V6s and the 5.7- and 6.4-liter HEMI V8s, with an 8-speed automatic from 2012 and available all-wheel drive.


Your 2021 Chrysler 300 is from the second-generation 300 (LD), which covers model years 2011–2023. Most procedures are shared with the other years of this generation, but engines, options and wiring changed from year to year, so the manual is made for the 2021 model year.
Check the model year on your VIN: on a 2021 vehicle the 10th character of the 17-digit VIN is “M”. Vehicles built for North America always carry the model year in that position; on some European or Australian vehicles it may be left unused, so in that case go by the registration papers or the build plate.
At about 5 years old, a 2021 vehicle is usually past its basic warranty. Typical jobs at this age are brakes, suspension parts, fluids, the 12V battery and diagnosing sensor faults with the factory wiring diagrams.
