fuel flush kit

[Miguel Corona]

My 2015 gmc sierra 1500 sle 6 cyl recently was brought in for an oil change to the dealer. I have about 119000 miles on it +. They said they recommended the fuel injection cleaner at this maintenance interval so I let them do it. On the way to where I was going after this cleaning and oil change (40 min away) the check engine light came on.  The obd2 code was P2269  Water in fuel .

Anyone know why this may be happening and is this normal? The check engine light had never come on until I did this procedure.

What should i do?

call the dealership and ask if they put an additive in the tank
