Start off with one day at drive thru noticed a loud tick and realized it was my Jeep. Next day MIL light comes on. Stop at auto parts store and read code. P0303, Third cylinder misfire. Single cylinder code.
Try the basics, new coil pack a couple plugs. Code back to #3. Move on to the injectors. Nope.
Move injectors and coils around.
Nope, #3 again. Fairly sure I have no wire issues and Jeep and Dodge forums get real catastrophic from there.
Possible bad valve, or bad lifter destroying cam. Hundreds and hundreds of stories all over the internet of failed Hemi 5.7 lifter/cam issue. Now I was real depressed. Still owe 6K and my Jeep is at 150K.
So I bring it to dealer on the hope they will stand to lifetime powertrain warranty that came with my purchase. I was skeptical from day one that it would ever be honored.
Well, they found I joined the thousands of folks in the Failed Lifter/ Cam club. Lifters on #3 stuck and gouged cam sending metal throughout.
Dealer is now installing new engine and motor mounts and manifolds if they are shot under that lifetime I never imagined I would need. I am relieved and grateful. At that mileage I am stunned.
This issue affects any Hemi 5.7 across all models. The Ram forums had the most stories as they are in more pickups.
Some think its related to MDS system that shuts down four cylinders at cruising. Some think a bad run of lifters or cams. Poor quality after the bailout?
It rears its ugly head as a single cylinder code p030X. Could be any cylinder but 3,5 and 7 seem to be the most popular. If a loud tick is noticed it is already done. Engine runs rough but doesn't fail. Seems innocent at first.
A lot of those stories folks are stuck holding the bag with far lower miles. If a dealer claims lifetime or million mile it really isn't BS. The catch is when repairs reach current value lifetime ends. But keep up on maintaining your ride.
I will be there now except for coverage on new engine.
Link to the many horror stories and some home rebuilds and I hope this doesn't violate rules, just trying to provide info for any Hemi owners.
