Unexplained engine stalling and starter sticking
I have spent some time researching the new wranglers and have come across numerous reports of the the 3.8L engine suddenly cutting out while the vehicle is cruising- sometimes at highway speeds. I have also read of issues with the ignition/starter becoming stuck while the engine is being cranked. Unfortunately, I have personally experienced this issue on one occassion while attempting to start our new '07 unlimited sahara.

Has anyone had any personal experience with these issues? I read one report of a woman allegedly almost being killed when she was hit broaside due to her engine stalling while she was attempting to make a left hand turn. IF true, I have very serious concerns as the new Wrangler is my wife's vehicle.

Aside from the starter "sticking" on one occassion, it has been a joy to own and drive.

There is a TSB for the stalling issue. I'm not worried about it.

JK recall
For what it's worth...

Spoke with the service director today at Parkway C-J in Clinton Township MI. He said he had not yet heard of a recall on the '07 Wrangler. I asked him if he had read any of the articles on the web pertaining to this issue. He said he had not. At his request, I forwarded a link (copied below) pertaining to the alleged recall. He said he would look into it and report his findings.

What he told me in a subsequent phone call is that there is in fact a recall on Wrangler JKs built prior to mid January 2007 (pardon me, but I forgot the exact date). As with all recalls, The fix will occur at no charge to the owner.

Chrysler said Tuesday it was recalling more than 80,000 2007 Jeep Wrangler and Dodge Nitro sport utility vehicles in the United States to correct a problem that could make the engine stall.

Chrysler Group, a unit of DaimlerChrysler AG, said the recall would allow dealers to reprogram a power module to remove the potential for a brief interruption of electrical power to the instrument panel and the engine.

The National Highway Traffic Safety Administration opened an investigation into the Wrangler in May after receiving reports of engine stalling. Chrysler said the agency has received about 180 complaints of engine stalling in Wrangler and Nitro vehicles.

There has been one accident linked to the issue, the company said, but no injuries have been reported. Chrysler will notify owners about the recall later this week and the work will be completed at no cost to consumers.

Hmmm... for what it's worth, I wouldn't use them for service if they are that uninformed... :eek:

weve been reprograming them for a good while now.G25 is the recall number.I honestly cant remember a customer actually having the concern.Did a couple Nitros today.If your service manager hasnt heard of it he is hopelessly lost and you should seek a more qualified service dept.....g:confused:

There was an earlier string about a month ago referencing the very same problem. I purchased my 4-door Wrangler in December and since then, the engine has stalled about 4 times while I was in drive. Every trip to the service dept. to try and rectify the problem proved to be a joke.

Three weeks ago, I received a recall letter informing me of the problem So far, fingers crossed, the chronic stalling has not occurred.

I got my computer reflashed about one month ago when I got my first oil change I believe its recall G25. Any ways I didn't know about it till my dealer Mancaris in Oal Lawn IL informed me.

That recall is not a fix---

I think the stalling problem is back. Own a 2011. Stalled while I was turning left across traffic. I'm not putting my kids in that thing. NHTSA has nothing on it. Only 2011 3.6L in Chrysler 200. Not the same engine, but could be same electronics. . . Has anyone actually figured out what the heck is going on with this? It's "hers" and I don't want her driving it until I have it fixed. . . Called svc dept and no reply yet.

I have a 07 JKU "X", 3.8L. At times I will let the clutch out at intersections or stop signs, and my engine RPM's will just go away, the engine starts running really slow and almost like it is "Diesiling". No matter what I do with the gas pedal, the RPM's will not come back ,I have learned to just shut the key off and restart, then it runs "normal" and seems ok.
Kinda scary when all you can see is KENWORTH Chrome coming at the drivers door !
I hope you guys figger this out..LOL "BH"

So I had a conversation with a 20yr vehicle maintenance tech regarding the stalling issue. Mine is an automatic. So the problem may be that I braked while turning at high speed (30mph). As I was not accelerating, my engine speed was roughly at idle. Because of my speed, braking, and turning simultaneously, the engine could have been overwhelmed.This could have overtaxed the power steering pressure switch and/or any power braking pressure switch. This would have casued an engine stall for an engine at idle, IF the power steering pressure switch is bad and did not automatically trigger my computer to increase RPMs to compensate for the load. . . Thoughts?

To test this, when I get home today I am going to run it at operating temp and, while parked, turn the wheel to maximum range and press the brake pedal. If my maintenance friend is right, the engine should stall.
