Build date 03-2012, 3100 miles and NO problems. I don'r worry about something I got no control over, it only makes you old. I worry to keep the rubber side down and the shiny side up. The rest is why there is a warrantee for.

 

I got my 2012 sport jku second week in December with a build date of 11-11 just over 16000 miles no problems so far.

 

4/12 4,000 miles, all clear....is this suppose to come with a check engine light, or just a tick?

 

build date: May 2012
miles: 1,053
no tick

 

I was about to start this exact thread when I saw this one.
2100 miles
3-23-12 BD
No tick......except on startup for about a second but that's normal after sitting for a few days.
I hope it stays that way. I traded an 09 Tacoma TRD 4x4 for my JKU and my dad looked at me like I was insane when I showed up in my new JKU. Said I'd better bring it back. I hate how he's always fking right. Time will tell.

 

Mines an 11-11 build date, 16,XXX miles and no issues.

 

I've got 11-11 build date with 3K miles. No ticking, engine light nor warranty issues.

 

I just wanna see some 12-11's with 25000 miles and no tick LOL about a hundred or so and I ll feel better!

 

November build date, purchased 1/20/12, 7,800 miles no tick... knock on wood...

 

Mine was built in August of 2011...13k miles and I have had the tick for a while but engine hasn't thrown a code yet
