What can fail
On some 6-cylinder gasoline vehicles, the coolant pump wiring can rub against the engine fan, damage, and break. This stops coolant flow, causing engine overheating and stalling. The 48V electrical system may shut down while driving, preventing engine restart after eco stop/stop or glide mode turns it off.
What the fix does
Dealers will inspect the coolant pump wiring, replace it if damaged, and re-route it away from the engine fan to prevent contact.
