Lol, right on! My brother's company had a Ford truck with a 5.4 and 500,000+ trouble free miles on it. It was running great when it was stolen. Yes, they were highway miles, but towing a 20-something foot trailer, always loaded heavily.

The Pentastar should be a 200,000+ mile engine, easily, with good maintenance and care. I wouldn't be surprised to see them hit 300k.

200k should be expected out of ANY engine these days, especially a world class mill like the Pentastar, unless driven almost exclusively on short trips.

I've got 100k on my 3.8, and other than oil use, it runs perfectly and has given me no trouble. I'll admit I maintain it meticulously, but I expect it to go 200k. No reason why a modern engine properly maintained shouldn't. The Pentastar is a MUCH better engine design and should go longer.

Let's see some 100k+ Pentastars. Surely there are some hitting the mark by now.

Up to 69k on my January 2012 build JKU. Trouble free.

2013-I have just over 49,000 miles. We've had two bad water pumps in the first 15,000 miles, but everything's been great since then. Our JKUR is a happy part of our family. Our Jeep is is coming up to its first major expense. New tires. The open country at 2s haven't really any grip for the mud any more, so we're upgrading to Mickey Thompson ATZ P3s. Can't wait!

Same here. 76K on my November build 2012. I had the oil filter housing split and replaced under warranty. I replaced a stuck caliper... nothing else beyond battery replacement and normal maintenance.

2012 JKUR Sept 2011 build, 31,000 miles. Took it into the dealer with the engine tick in May 2013 with 8K miles and told normal by Dealer and told wait for check engine light by Chrysler Care. Still hasn't happened 3 years and 25K miles later! Seems to run fine. Serviced every 6 months by Dealer.

2012 JKU purchased in August 2011. 51,000 and just had the head issue happen 2 weeks ago. Dealer fixed and it's running great again.

Just rolled 120,000 on my 2008. So far I had to replace the master slave cylinder, the brake fluid reservoir, and the clutch. The springs and shocks were shot (just installed a lift). There is a ticking sound I can't locate though...

were showing 20k on the odometer...could be slightly more on the tires
