Owner report 11536714 · 2023-08-05 (August 5, 2023)

Driving down a multi-lane highway at 70 mph, a 48V battery malfunction warning goes off as well as the yellow check engine light. A few seconds later a ‘coolant’ error alert pops up. SUV loses acceleration with power dropping from 70 mph to 55 mph to 35 mph. Another message displayed on screen warning me to “Pull over and turn the engine off.” Narrowly missing being hit from the back, I was able to coast to an upcoming exit into a store’s parking lot before the car stalled completely.
