2012 GC Laredo V6 Engine Tick

I've had the vehicle for 2 months. I originally noticed a ticking coming from the timing belt area of the engine a few days after purchase..figured I would let it go until the first oil change. Took the vehicle in yesterday (4/2/12) with the complaint and was advised there is NO problem with the engine. I asked to listen to another GC with the same specs and I did not hear the tick in that vehicle. It's an obvious TICK that increases with RPM's. I know engine ticks are caused many different issues. Anyone had ticking issue with their 2012? An engine tick, any tick, is not normal in a new Jeep, correct?

Re: 2012 GC Laredo V6 Engine Tick

I had knocking like noise when the car hit 5000 miles. Changed the gas to higher octane and now it's fine.

Re: 2012 GC Laredo V6 Engine Tick

This is a big issue in the 12' JK forums here and on jeepforum.com. I would try searching through some of those threads. I have an 11' and I have had a faint clicking/tapping noise since day one. I've got 22k and have never had a light come on and its never gotten worse. Supposedly the issue has been narrowed down to certain build dates and it has something to do with the valves/heads and usually throws a cylinder 4 misfire code and the CEL comes on. But again, I'd check in some of the JK forums, seems they have the worst of it. Also try searching youtube for "2012 wrangler engine noise" - if yours sounds like that you might have an issue. Some of them are sounding really loud - like a sewing machine. Mine isn't like that at all, it's barely noticeable.

Personally, i'm not worried. The minimal "tick" I have sounds no different than the lifter tap I had in every GM v8 I ever had. I think there is a fine line between a small isolated incident that seems to be under control for the most part, and the internet forums making it sound like every v6 w/ any little noise is about to blow up!

Re: 2012 GC Laredo V6 Engine Tick

It's more of a fast tick, tick, tick than it is a knock. I will, however, give the gas a try.

Re: 2012 GC Laredo V6 Engine Tick

Does it sound like this?

I just tried posting something longer but it said mod. had to approve so who knows if it will ever show up. Anyway, the 12 JK's are having a lot more issues it sounds like. I have a 2011 WK2 w/ 10/10 build date, I've had a light tap/tick from day one but never any issues. Mine definitely does not sound like the one in this video.

Re: 2012 GC Laredo V6 Engine Tick

That's the noise albeit not as loud. Felt like I was getting the run around at the dealership after they said there were no issues..now ever more so. What do to what to do...

Take it to another dealer look for 4 or 5 star rated dealership in your area.

Re: 2012 GC Laredo V6 Engine Tick

Are you sure the "ticking" is not the fuel injection system? On my Mustang GT you can actually put your finger on the metal fuel rails, and it gets quieter. The timing belt on my GC will tick a little when it is cold. But the hood has to be open to really hear it much. You definitely cannot hear it inside my GC with the windows up. And if I did, I would just turn the music level up a tad...

Best luck with your diagnosis.

Re: 2012 GC Laredo V6 Engine Tick

Mine has a tick when first started and a slight one all the time. A tick when first starting is fairly normal in modern cars while all the hydraulic things (lifters, lash adjusters, cam phasers, timing chain tensioners, etc.) all pressure up. The slight tick all the time I figure is just the injectors and doesn't bother me. No MIL or drive ability issues and can't hear it inside, just outside or with the window down.

Also, if you have a ticking timing belt you've got serious issues since all the available engines in the GC are chain driven...

Re: 2012 GC Laredo V6 Engine Tick

Just noticed the tick decreases about 70% when the vehicle is put into gear. The dealer told me all 2012's have that "tick" to some degree. The said some vehicles are louder than others. I will keep and eye on it for sure.

Re: 2012 GC Laredo V6 Engine Tick

I only hear tick noise with windows down. I first noticed this noise several months ago but didn't care much since I thought it's normal. It's coming from bottom of the car, not from the engine.
