Well, I don’t think I can trust this vehicle anymore. Took my 2.0L JLUR up to Brown Mountain, NC for the first time. Relatively easy trail. 4 LO and disconnected the sway bar and off we went. Everything was great. Took it nice and slow.
Then the following happened:
Battery Light
Loss the entertainment system
Random other systems started falling offline
A/C went
Pretty much every light came on
Vehicle stalled. Dead battery. WTF.
We were like 8 miles from anywhere. Fortunately, a side by side came along and gave us a jump. We took it out of 4 LO and limped back to the trailhead. Of course, everything came back once the battery was recharged. Drove home no other issues.
I took her to the dealer the next day and they read 40 or so low voltage codes. It seemed exactly to be the symptoms of alternator failure in other vehicles. Everything checked okay though, dealer could not duplicate.
My theory. At low rpms, especially while in 4 LO just taking your time, the system uses more juice than the BSG can generate to replenish. Took about half an hour before the vehicle died. Anyone one else experience this?
I’m heading back in a few days and I’m going to try to duplicate it. I’ve got a portable jump starter for back up.
Needless to say, until they can give me a definitive reason why it died, I’m not taking it anywhere where I could get stuck. Disappointing for a JLUR...
