Fuel injector

[Denali 19th]

Just had a fuel injector replaced on my 2019 Yukon with the 6.2.  The dealership also replaced a couple fuel lines too... Is this normal?

Sure this gen of 5.3 and 6.2 have had plenty of injector issues.  The lines are replaced because they are a one time use component.  

 

$hit happens.  

 

Try to run top tier fuel as much as you can.  If you can't, run some good fuel system cleaner every once and a while.  Amsoil P.I., Chevron Techron, BG44K are some great examples.  91 or 93 octane ONLY in the 6.2.
