What stands out
No new NHTSA electrical complaint has been filed on this vehicle in over 7 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
The intent of this service bulletin is to identify aftermarket ALDL or DLC interface devices as potential sources for causing multiple customer concerns that do not have other diagnostic methods to identify them.

The failure pattern owners describe
Owners describe several distinct electrical failures in the 2015 Escalade. The most serious involved loss of electric power steering and complete brake system failure, both occurring under what appear to be recall situations but with owners bearing repair costs before recalls were issued. One owner paid $1,207 for steering repairs before receiving a recall notice, then was denied reimbursement. Another experienced total brake failure at low speed, causing a collision, after a recall was issued but not communicated by the dealer.
Rear hatch locking mechanism failures appear multiple times, with reports of the latch not engaging fully and one owner documenting an open flame in the mechanism. One failure allowed exhaust fumes to enter the cabin. Climate control electronics independently maxed out the rear heat, causing an occupant to pass out at just 6,000 miles.
CUE infotainment system problems include screen delamination disabling backup camera, Bluetooth, GPS, and radio functions—creating navigation hazards. Other owners report the system freezing, changing settings on its own, and becoming completely unresponsive. A radio head unit flickered and failed at 68,000 miles. One owner also reported intermittent no-start conditions.
