Consumer Description

Engine failed at 142,000 miles. No prior indications or warning lights. Cam roller failed on cylinder #7 intake causing rod to throw through head cover, and valve to drop into cylinder #7 piston which damaged piston and disable engine. I have been advised that this was caused by the Variable Displacement mode the engine goes into when not under load, for better fuel economy. I have also been advised that this issue is not uncommon for these 5.7 Hemi engines which are advertised to last 200,000 to 300,000 miles. I had to replace engine and loss of use for 4 weeks. Not happy with Chrysler/Ram/Stellantis. I feel mislead/cheated.
