Think about how many hemis are made and then look at how many have problems, noone ever goes online to praise a product, most people only care to go online and complain when something goes bad, i have 2 hemis and have been perfectly happy with both of them, unfortunately in any mass produced product there are going to be defective/faulty units, its the way the tolerances stack up and go together, and the materials and everything else.


Unfortunately i do NOT have the production numbers to compare to the failure numbers but he 5.7 has been put into basically EVERYTHING over the last 15 years and in alot of cases (at least as i understand) it is the best selling engine option.

 

I spent 3 years of my life as part of the design team for the new hemi which was introduced in '03 (water pump / cooling system). I know this was a good engine but had reservations when the modifications came along (VVT, MDS). We had to squeeze down the thickness of the water pump to make room to get the engine into the car bodies (to meet the 5 star crash rating, they had to have more crush room) and for the cam phazer. I was reassigned to other things before the changes went into production.

I still think they should do the right thing and help customers with the failures. I have been in the automotive industry for 42 years and "things happen" is not an excuse.

Indeed. The manifold was a bad design. End of story. Their testing apparently wasn't thorough enough.

 

i agree with you, especially on the last part, i was just pointing out that the majority of these engines (vast majority even) are trouble free throughout their lives.

No engine is 100% perfect or else all vehicles would have the same engine in them.
