580 Miles and already a problem...

I've had my 2012 JKU Arctic for about a week. It has 580 miles on the odometer. CEL came on this morning about a minute after starting her up. Plugged in my scanner and got a misfire in cylinder bank #2 and crankshaft position sensor error. WTF??? at 580 miles?

Sometimes, sh*t happens. I have 33000 miles on mine without any problems at all.

Or it could just be a bad CPS. Under warranty and about a $30 part.

That has to be a record on a 2012. I bought mine in August and only have 5100 on it.

Yup, sometimes sh*t happens. My build date is 12/11. I don't hear any abnormal ticking from the engine. Taking her in tomorrow.

Sounds like you just got unlucky with a bad crank sensor. I had the one in my old 350Z go out around 8500 miles and 11 months into owning it. I was concerned that something like that went out and here is one of the responses I got when I'd posted about it............

Quote:
Its a part that has a hard to manufacture semiconductor in it. Manufacturing defects will happen so its possible its just that.
At least yours went out in the driveway. Mine died on the freeway and I had to get towed to the dealer.

Doesn't show all that in the app version of the site. Don't understand why someone would be comparing their '10 to the '12 though.

Not a wrangler guy yet but i have a cherokee 08 and i know for a fact that misfire codes are common because the electrical systems are extremely touchy, i used to get them all the time on my 08 srt8 crank positioning sensor might be popping up because of the misfire and the crank sensed the vibration from all 6 not firing correctly for a brief moment. could also be a bad sensor, those are known to go to. have a starscan at your local dealer clear them and see if they come back.

I have a DashCommand for my iPhone and the ODB2 interface. I can clear the codes if I need to. Just a little annoyed it happened at 580 miles.

I plan on enjoying everyday with my Jeep. I'm already drawing up plans to make my own bumpers.

Mine had a tick at around 700. Turned out to be bad ac compressor. It locked up and burned the serpentine in half. Luckily I was very close to the dealer and they took one off a new one and I was on my way. I bought mine dec 3 and have a little over 10,000 miles on her.

Yes. I didn't mean to imply otherwise.

My point was that sometimes, regardless of the quality of the vehicle (or its engine), things go wrong. I sensed a little frustration with the vehicle from the OP's post and wanted to simply (and with a little humor) state that one problem, regardless of how soon it occurs, does not necessarily reflect poor vehicle quality. That point applies if one has a 2010 with a 3.8 (like me) or a 2012 with a 3.6 (like the OP).

The phrase "sh*t happens" states that paragraph much more succinctly (if not as clearly). Hope the OP gets his problem solved quickly.

It turned out to be a bug in the computer. After the flash, it's all good.

Now what is this "Dash command" that you speak of and how does it connect to the OBDII port thru the Iphone? BTW Glad your prob was minor!

DashCommand is an iPhone app. I think it's $50 on the App Store. It uses a wifi->OBD-2 link. The interface I have is the PLX Kiwi wifi /w mod interface.
