If it’s flashing definitely misfire, first time it happened took it to dealer and they did same thing to me, said they do it all the time reset codes and let be on their way, second time took back to same dealer who kept almost a week to tell me I have to wait 3 weeks to get it diagnosed to find out what’s going on because they only have 2 OEM certified mechanics and one was out sick and other one had been working on a transmission job that they just got the part after waiting a month for. Took it to a GMC dealership who had it diagnosed within 30 minutes of me taking it there. Needless to say don’t always trust first dealership you take it too. It just took longer waiting on parts. GM needs to do a recall on this crap because you pay $60,000+ for this and you get nothing but junk but they don’t care because it’s big company lining their pockets

doesn’t sound like this is happening with the diesel version?
Don’t think so but if it was you from what I have seen you can get those injectors all day. Just the 5.3 and the 6.2 are both having injector problems and those are the ones hard to get back ordered
I believe they are supposed to add the down time to the warranty on the back end. Get that info in writing from the dealership when you go in. They should be able to print out those details.

Our Babymax had injector codes, but dealer wasn't liking the intermittent nature and dug deeper. Found an braded harness at the alternator bracket.
Did any of you have a repeat occurrence once injectors were replaced?

You're lucky! Very few true troubleshooters left out there. Glad to know there are at least a few.

My 2023 Tahoe Lt with 14k miles just got towed today to dealership for the same problem. Hoping it get fixed correctly, the whole reason for spending all this money on the new car was to feel safe riding with kids.
Just had the same issue with my 2023 Tahoe Z 71 with a 6.2. Turns out it was a ignition coil problem. They replaced the ignition coil and we will see keeping my fingers crossed.
