What he saidFirst off, "lifetime warranty"? I have never heard of any company, offering a lifetime warranty on any vehicle in Canada. So it's either Canadians getting screwed again or someone is making something up...
Next, sorry if someone has already said this but it's a long thread and I don't have time to read through all the comments...
But, I would say the reason Chrysler does not offer a lifetime warranty (if it even exists) on the 3D is not because of it's short longevity but rather the opposite. Any engine that lasts a long time likely means the vehicle it's in will be on the road for a long time. The longer a vehicle is on the road, the more likely other things will need repair just from wearing out from normal use. If they aren't offering lifetime on the 3D, it's because they know these trucks will be around for a long time and it will cost them too much. 200,000 kms on a hemi vs 400,000 on a diesel = higher cost of lifetime warranty for the diesel.
