New 3.6 Engine and Engineering Changes

I retired from International Truck and whenever there was an engineering change to a vehicle such as the new 3.6 engine for the Wrangler, Assembly and Operational problems would always show up. Engineers would go to the assembly plant and many times initiate modifications and changes that would be adopted into an engineering change to the truck. This almost always happened with new features.
I would expect this to happen also with the Wrangler's new engine. Many times it is wise to wait purchasing a vehicle until all problems are worked out. Just my 2 cents.

That may be, but this engine has been out for awhile and used in other vehicles. It's only new to the wrangler. Few problems have been reported.

I'm not talking about problems with the engine. I'm talking about assembly and engineering problems with other components that are affected by the 3.6.

Waiting a year or so is a fine idea and something that's been mentioned before. Can't hurt.

However, it really only works for those who already have a Wrangler that they'll be selling/trading. If you don't have one yet, would you have them wait--Wranglerless--for an undetermined amount of time to avoid potential problems that may never arise?

Madness!

Since I have to wait til spring to buy one anyway, I'm having the same thoughts. I'd like to see how the new engine is woven in there on the final product. Not that it will keep me from buying one.

Talking

I think you are 100% correct broomhandle. So why don't you buy my 11 sahara tan wrangler 2 door with every option except the rag top. And many nice mods. Then I can buy a 12 with the 3.6 and be a guinea pig for jeep. Just hit 5 k yesterday and the top doesn't leak and has never been off. Cooling trany pan and I just change oil at 4400 miles and put 85-140 full synthetic valvoline in the front and rear pumpkins. Also changed the trany fluid at 1400 miles when I installed the oversized cooling finned aluminum trany pan. Oh and reinstalled the super famous skid bar, which is another of jeeps new additions. Also used no oil up to the 4400 mile oil change, which I did myself. This jeep has never been back to the dealer and may never have to go if u take care of it. We can't say that about the 12 models with the tiny smaller little 3.6. They will probably be nothing but trouble for years to come. By the way I have been around corn binders all my life and they are a good all around truck. We uses to run the paystar 5000 trucks in the oilfields and I know a lot of them from the early eighties are still running today. My dad run the old B models back in the sixties with the 549 gas engines. Quite a engine back in the day, before the diesel craze took over the heavy truck market.
