Absolutely. While a vehicle is under warranty, any and all maintenance and servicing should be done at the dealer. Once the warranty is over, then you can DIY or choose a different shop if cost is an issue.
Since sludge is mentioned and now the CEL is a factor I start wondering how often “changes the oil frequently” actually translates to. Wonder if this is related to a variable valve timing solenoid, etc?
If sludge is a factor than Firestone did not do this. Along with oil change frequency I also wonder how often, if ever, the hood comes up to check the motor oil level. Chronic low motor oil levels will contribute greatly to a sludge problem.
My first inclination was that Firestone (whom I am no fan of) might have botched this but second thoughts with added info tends to say no.

Sounds to me like they did put wrong fluid or some such thing and fed your wife a BS story about sludge to try and cover their ass. You really need to be there when the car is picked up and to get a FULL explination of the reason why they had to keep it overnight. A mechanic needs to be with her to make sure what transpires is all above board!
Sidney , DB is not the one with a problem.
