Asked by Guru941JF4 Sep 16, 2020 at 05:13 PM about the 2018 GMC Yukon XL SLT RWD

Question type: Maintenance & Repair

My 2018 Yukon XL is slow to start and seems to be a strain on the battery. I
pulled into a battery store and the Battery test health state shows 91. Charging
state shows 9 yet the alternator is working fine. Ideas on what else to check?
