Last week I took my 2015, Suburban to the dealership for its 100K recommended service. Prior to this service I had no problems with my truck. The service included oil change, tune up, fuel flush treatment, transmission flush and radiator flush, and tire rotation. One week later I was driving down the street, and my engine started shaking the car. As well as the car sputtering. So I immediately pull my car back to the dealership where I just received my 100K service. They call me, as said my" Fuel injectors 3 and 7 are misfiring. This was bounded to happen and it would cost $1000 to fix." So my question is would a bad tune up cause my fuel injectors 3 and 7 to misfire. Or is this a problem I have to suck it up and bite the cost? Thanks for your time and assistance with this matter.
How long has your 2015 Chevrolet Suburban had this problem?
RepairPal Certified shops can diagnose and repair your 2015 Chevrolet Suburban. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
A normal tune-up of just replacing the spark plugs and the other items you mentioned wouldn't directly break an injector. It's going to be hard to prove anything here but I suggest getting a second opinion. Use this link to find a good shop near you.

Ask to see official documentation from GM that the fuel system “flush treatment” is even a suggested procedure..
It’s simply a way for the dealership to make more money!
They’d be fixing MY vehicle free of charge !!
