    Cabin Air Filter @ 19K Miles -- photos

    In my case, that was many years ago -- pre-internet -- when if you wanted OE parts, you had to go to the dealer.. Some may have even had 3 price levels:: * Retail/MSRP * Commercial -- price an independent shop would pay * The price dealers would charge each other That's my recollection...

    Cabin Air Filter @ 19K Miles -- photos

    The description sounds good. Without any independent testing, it's impossible to know how any auto filter performs. For example, for water filters there is NSF, WQA, and CSA. For vehicle filters, there is no independent testing lab(s) -- AFAIK. This (from the Amazon page) is odd: Under...

    Battery failing again and recall

    Well said Brian, spot-on!

    Rough start?

    Sounds good! I'm glad the problem seems to be resolved.

    I've had that experience before -- inconsistent results.

    Cabin Air Filter @ 19K Miles -- photos

    IDK if this is still the case, but years ago, when you'd call a dealer's parts dept and ask for the price on a part, they would invariably quote something very high. Then if you'd ask if you could get the wholesale price, they'd almost always say yes and knock a large percentage off the price...

    Trip Report: Toroweap Overlook, Arizona

    My mistake, I misread I17 as 117. You mention other drivers saying he was riding his brakes -- do you have a CB? I still have one in our RV but it is not as useful as it used to be. Yeah, semis have Jake brakes for a reason...

    Defective Battery, Recall 24S24 and other topics

    Helpful post, thanks! The culprit is clearly, "... a sudden drop in the battery charge sufficient enough to prevent the BS from restarting because the battery suddenly became defective." No other possibility. :cool: j/k That is what the recall refers to: :...a sudden change in the 12 volt...

    Defective Battery, Recall 24S24 and other topics

    After we each called a couple times and got voicemail, my wife spoke with someone at our local (selling) dealer's service dept today. They said, "We're booked solid for a month. Continue driving at your own risk! Ford Motor Company is not responsible for accidents, injuries, or deaths...

    Trip Report: Toroweap Overlook, Arizona

    Great write-up and excellent photos! Does 117 have steep grades? Asking because of the semi's brakes catching fire.

    Defective Battery, Recall 24S24 and other topics

    Very helpful, thank you! I didn't see a voltmeter mentioned at either link, but maybe I missed it. Either way, that's useful. Cool that you can calibrate the mpg reading (which is usually optimistic).

    Defective Battery, Recall 24S24 and other topics

    Agreed! A built in voltmeter with reasonable accuracy would be a tremendous help! We could tell at a glance if the charging system is working. Perhaps there is a 'meter' that plugs into the 12V outlet that has acceptable accuracy. As it is, I check the battery with my Fluke meter and I...

    Defective Battery, Recall 24S24 and other topics

    That raises another issue -- aside from "which came first, the dead battery or the defective charging system..." when people have a problem and get the battery replaced, they usually say they lived happily ever after ('problem cleared'). Of course, as you said, the replacement battery will...

    Defective Battery, Recall 24S24 and other topics

    Since you have a 2022 BS, and the battery failed in the fall of '23, I'm guessing it was <2 years old. So, was the battery bad, or was it the fault of the charging system? Since you said: "I took battery out and walked it over to an auto place store. They charged it in order to test it and...

    Defective Battery, Recall 24S24 and other topics

    Aside from smokin' hot areas (Phoenix; parts of Texas; the CA desert) 32 months is a very short lifetime. With these failures, there is a question as to whether the battery was bad to begin with (or initially OK, but then experienced a failure like shorted plates) -- or the battery was...

    Defective Battery, Recall 24S24 and other topics

    "...an AGM battery. It gave me little warning of it's pending doom. One day working, the net day completely dead." That's exactly what the recall seems to refer to with "Sudden degradation" and "sudden decrease in SOC." Similar to your Grand Cherokee, the Sprinter chassis our RV is on has an...

    The new Recall is out now.

    I must have missed this when it was first posted. I agree that: "The term "sudden degradation" doesn't tell us much about the cause. For example, the way this reads suggests the battery is fine one second then bad the next." Exactly, that's impression I get as well. It is also true that a...

    The new Recall is out now.

    From "Battery University" (See link in post #67): "Electrical short is another failure mode, especially with starter batteries in trucks. As the battery sheds its lead to the bottom of the container, a conductive layer forms that gradually fills the allotted space in the sediment trap. In...

    The new Recall is out now.

    Same here. OE battery going strong since 3/25/22. Of course, that's to be expected. I use a BT maintainer, but when I intentionally leave it disconnected for 2-3 days, the voltage doesn't drop much. Again, that's normal. Most OE batteries seem to be good, but judging by the posts here on...
