The dodge rams -just one example had the weird alternator problem going back to the 93-o3 bodystyle, when the battery got too low you had to boost it and drive it for at leat an hour to recharge, then there was the ac glitch problem with the -03 ups my buddy wouldn't deal with--some $1100 part just to get the ac working again~ but that sure was a burly looking pickup.............


on the other hand Gm didn't make a pickup that looked worth a damn since 02, and a reliable engine since at the latest 2007 (on certain ones) then the went all DOD ~~ and it gave em so much problems the marketing people changed the name to active fuel management,,
the only GM vehicles not equipped with dod were manual transmission cars, vans, I don't know if you could still order a HD truck with a 5 speed manual

people with new trucks are still dealing with the cyinder deactivation selonoids going bad causing their cams to go bad, I was thinking a 2009 aluminum 330 horse lc9 would make a great engine to build... I had read you could just rip the dod stuff out, then I found out it costs more for that kit than what the block cost me and the other kit to remove the VVT cost another $250. I sold the lc9 (at a profit) and switched to the L33's The guy who bought it --his 2010 AFM had wiped out the engine.........
Still having the same damn dilemma 4 yrs after they introduced the cyl cutout scheme,
I have heard the direct injected engines are also still suffering the problem.
