Just got this diagnosis today on my truck. 2015 GMC Sierra 6.2. They said all injectors were bad at 44k miles with cylinder 6 being the worst. Quoted me $2600 for the job. Spoke with my independent shop and their outlook wasn't much better. They couldn't even find the parts for this direct inject engine (GM strike). Called the dealer back and they said GM was going to cover 50% of the cost under GM assurance. If anyone else has this problem ask about that.
