So, My 2009 Yukon Denali throws the "service battery charging system" message on a daily basis. The little red battery light comes on as well and stays on for varying times. The message seems to only come on while the truck is idling or moving at slow speeds (like when I drive down my muddy driveway or stopped at a light). The battery light may be displayed anywhere between 10 seconds to 30 minutes. Performance of the truck doesn't seem to be hurt in any way however the voltage gauge doesn't stay super consistent while driving. I had the old battery checked and replaced shortly after I bought the truck a couple of months back since it had trouble starting. Other daily symptoms include flickering lights and screens while at idle. Yes, the battery cables are corrosion free and securely attached to the battery itself.
Anyone else experience or have a solution to this issue?
I replaced these wheels with aftermarket at the 2,000 mile mark. They are like new, as you can see in the pictures. I'm selling them all together (four Denali wheels, the spare, and five Goodyear Wranglers with full tread life). The Wranglers are 265/70R18. The 8x180 lug pattern is for the HDs, but they can be adapted to different lug patterns if you're trying to update an older model truck.
They're all beautiful with no curb scuffs or damage of any kind. I'm asking $1,000 for all five, but I'm somewhat flexible on that if you make a solid offer early. You can come pick them up, or I'm willing to ship them if you're willing to pay the shipping. PM me if interested or post publicly if you have any questions that could benefit the group.
After being down nearly 6 months the Denali is almost finished. The shop based out of Hudson, NH “Granite State Dyno and Tune” has been incredible. Super professional with absolutely top notch craftsmanship.
