Within 3w of getting the car serviced, I had some error messages. I took the car to the service center and got the bad news that it was a PEM failure. I thought I read here somewhere that it's possible that it's a PEM fuse and not the entire PEM so I pushed back and asked the foreman to doublecheck the fuses. It turns out it was a fuse. $400 instead of $8900. Thank you forum!
