Alternator crapped out 2012 JGC

Purchased a 2012 Laredo 3.6 v6 about 2 months ago, 33k on the clock. Love the jeep but after reading thru this forum its a little scary.
While driving to town two days ago I noted the battery indicator showing I went back home shut off the jeep and restarted, indicator was off so I headed back to town. After about 2 miles the indicator was back on.
I called the dealer where I made the purchase and was told to bring it in and they will check it out, they are about 25 miles away and I'm wondering if it will make it that far. Nope, half way there it shut down and there I sat along the road, the jeep completely dead. Called the dealer and they directed me to call Chrysler roadside assistance, flat bed showed up and had to jump the battery to get into neutral. Dealer checked over the jeep while I waited and then told me the alternator is bad. They have a new one in stock and will install now, so I can be on my way. Great, except after installing they told me that the new alternator is not charging, and they are not sure why or what else could cause this.
They called for a rental car for me and said they will continue trying to figure it out. Heard back from them the next day and they say it's still not fixed and they are waiting for a return call from Chrysler engineering to help figure it out. My odometer is now at 35750 so this is covered under warranty, so other than inconvenience I should not have any charges. Anyone have any ideas on the cause of this problem? I know back in the old days it would probably be the voltage regulator, but that was then.

Re: Alternator crapped out 2012 JGC

There is a recall out on the stock 3.6 alternator P60 / NHTSA 14V634000 "Chrysler Group LLC (Chrysler) is recalling certain model year 2011-2014 Chrysler 300, Dodge Charger, Challenger, and Durango; and 2012-2014 Jeep Grand Cherokee vehicles manufactured April 22, 2010, to January 2, 2014, and equipped with a 3.6L engine and a 160 amp alternator. In the affected vehicles, the alternator may suddenly fail."

It did seem odd that my trailer towing package did not include an uprated alternator so I have the stock 160.

I have a notice that when they have the parts to fix, I will be notified (expect they will exchange the alternator).

Voltage is one of the parameters I monitor with Torque Pro.

ps when going any distance, I carry a jump box.

pps the best answer since the electric power steering seems to be a factor would be to fit the 180A alternator. Right.

ppps The defect notice makes for interesting reading.

Yes I got a notice on the recall, in fact I had the letter with me on the way to the dealer. When they told me that the alternator went bad I requested that they replace it with the 180 amp unit so I wouldn't have to worry about the new one. They told me that Chrysler will not go for that, and I will have to come back for the update as soon as they figure out how they are going to fix it. However they said that since it failed this soon that I'm on a "special list", per the Chrysler rep., to get the update ASAP. Wow I'm impressed.

Thanks for the reply

I am sure that any vehicle that is experiencing the issue has a higher priority than one that is still operational. Does not help much if they have no parts and refuse to upgrade to something they do have.

ps " I will have to come back " how do you do that if you do not have an alternator ?

Update from dealer: Chrysler said to try another alternator. They did and as they suspected it didn't cure the problem. They now believe that the defective unit is the PCM and have ordered a new one for replacement they think that this will take care of the problem. I hope so as I miss my Jeep.

Re: Alternator crapped out 2012 JGC

Interesting. GM alternators used to have a tab you shorted to ground that would turn an alternator to full output. That way you could quickly diagnose many problems and eliminate/identify an issue with the alternator .

I have also tested many alternators just with a big vise, couple of jumpers, and a 1/2" impact: they are not that complicated.
