Lets hear some of you all’s or commonly known 6.4L challenger problems or issues. Just curious to see what is y’alls experience with issues in this car.
Classic ?My engine sounds too good, which makes me want to step on the gas pedal more, resulting in poor fuel economy.
Also heard that 6.4 auto transmission sometimes has problems like rough shifting. Is that true? I assume its normal for it to shift less smooth as it ages but i want to know if its a reoccuring problem.The only issue has been the Water Pump. On my second. First at around 25k miles and again at like 59k miles. Besides that the only other problem is finding a track close to where I live to let loose!
I have seen some TSBs where the PCM/TCM were reflashed to improve drivability on the older models. Probably not an issue with the newer models as the usually get the latest and greatest calibrations.Also heard that 6.4 auto transmission sometimes has problems like rough shifting. Is that true?

Remote start?not particularly for the 6.4L - but i wouldnt mind being able to open my car in the mornings (when below zero, with propper precautions) without getting a mini heartattack that i might fk up my window mechanism.

As i said, even with proper precautions. Maybe if i waited through 2-3 Remote start cycles but im not letting it idle that long.Remote start?
Honestly, a lot of the problems i hear from people on challengers are almost always for the RT and ive never seen anything like that on a 6.4L. Only thing ive seen happen is a friend of mine had a 80k mile scat pack and the transmission would shift pretty rough at times. Normal acceleration and normal driving, everything street mode and nothing really tuned. Still the A8 is a great transmission and I kinda wanna save a little fuel with MDSI’ll stop short of calling it “common”, but the Hemi’s propensity for eating camshaft lobes (after corresponding lifter failure) is a known thing.
The failure rates are definitely skewed more toward the 5.7L Hemi engines, but this failure has occurred with the 6.4L Hemi also, so it’s not immune by any means.
I received this TSB, and it really improved the 1-2 shifting. It used to get some resistance and sort of "clunk" to and from a stop. It wouldn't make any clunky sounds, but it definitely felt like it wasn't shifting properly. I doubt it did any damage.I have seen some TSBs where the PCM/TCM were reflashed to improve drivability on the older models.
