Lifters just went out on my 2017 6.2, 115k miles. Total cost to repair was $5,600. The performance shop that did the work said they do the DOD delete 8-10 times a MONTH. Some of those are jobs are pre-emptive.
If you buy a late model GM, you should set 5k to the side for the high probability that your lifters are going to go with the potential of further damage happening as well, I had a pushrod that was also bent. The AFM/DOD system is pure Democrat inspired climate change virtue signaling bullshit.
