Jeep Grand Cherokee Recall: potentially dodgy alternator

Jeep Grand Cherokee sales softened off almost 50% in 2016.
Jeep Grand Cherokee sales softened off almost 50% in 2016.

Jeep has issued a recall on the Grand Cherokee 4X4, for some potential problems in the electrical circuit.

The recall notice says that the “alternator of the affected models may experience diode thermal fatigue due to cyclical loads induced by the electro-hydraulic power steering (EHPS).”

In short, if your alternator on your late-model Grand Cherokee carks it, or you’re going through batteries too often, give Jeep a call to get it sorted out. There is also a chance of the diode really going belly-up and shorting out, which could lead to all sorts of exciting stories to tell around the campfire.

The recall affects 9,566 vehicles in total, also including the Chrysler 300C sedan. Based on that, we’re going to assume it’s vehicles with the 3.6-litre Pentastar V6 that are affected.

  • we have a grand cherokee 2013 & had our alternator replaced under the recall in august 2018 and since then my car will randomly not start.. do you think this has something to do with the alternator? we replaced the battery thinking it was that, but it still randomly doesnt start. quite frustrating, especially when i have two toddlers in the car.

  • 2014 Jeep GC. 3.0 Diesel. Alternator stops charging the batter, then starts charging again at random times. Mechanic says I should go to a Jeep Dealer for the recall, but it looks like the recall is for Petrol only. Any updates from any winners out there?

  • CRD Grand Cherokee, bought late July 2018, alternator and battery died late August 2018, replaced under used car warranty. Just happened again yesterday, WTF.
    I live in the hills east of Melbourne, it is extremely dangerous to loose power steering and brakes in this area.
    How do we force FCA to include our vehicles in recall?

  • Two weeks ago, 3 days before driving up to Qld from Sydney for vacation. Broke down in scorching heat with 3 kids in the car. Steering locked, abs light when on. My jeep is done 51000kms, its a baby still. Took it to hartland Jeep Chullora, Quoted me $5.5k for alternator and computer module and refused to give a report for it. Dodgy they were never again! 1 week Prior at hartland jeep spent $2300 on service, powersteering oil still low, and light needed to be changed, charged me $700 for it and never changed it. Called FCA advised alternator fault only on petrol not diesel. Dead end for me. Most electricians/mechanics say it a recall for both diesel and petrol cherokes. Need to be investigated and we need all owners to be reimburst.

  • Is this planned obsolescence!
    My 2012 Jeep Grand Cherokee alternator also gave up with flashing console and loss of power steering yesterday, 30/12/18.
    ABS also made braking hazardous. This on a main highway with holiday traffic!
    Not impressed and will take advice!

  • Same thing just occurred to our WK JGC CRD with just over 100,000 km on the clock. This is on the back of replacement air conditioning unit and serpentine belt tensioner pulley totalling over $4K. Worst car I have ever purchased in terms of reliability.

  • 2012 JGC Overland CRD alternator failed in highway traffic half way round a bend and loss of power steering, Thank goodness all okay, but seems to be a very common fault with diesels as well. Take notice FCA, when is this recall coming

    • Same car, same problem. My WK2 Diesel just completely shutdown along the highway and went into some strange recovery mode that was very scary for my wife and 3 kids. Mechanic has since told me the battery and alternator need replacing, coming on the back of a $2500 service only 2 months ago. Looks like there no trip to Brissy for Xmas our family … very frustrating Jeep and FCA.

    • My alternator went in my 2012 grand cherokee diesel yesterday. $1088 to fix with nrma. Not what I needed at Xmas time. Getting rid of it as too many problems with mine lately.

  • Same problem. 2012 Grand Cherokee 3.0 litre diesel. Only 122000 km. Alternator died while driving. Everything shuts down. Very lucky to have it happen in a relatively safe spot.

  • 2014 Grand cherokee 3.0 Diesel at 55k alternator died. FCA would not fix saying only petrol versions are affected. I don’t think so.. all the grand Cherokee models are faulty..

    • My diesel 2012 went last night – alternator says the nrma- i have 120k on it – shouldnt have happened – will be investigating more tomorrow

  • Yet another Jeep major issue, who in their right mind would buy a piece of American crap without any back up or support worth mentioning.
