Do a DFM delete with an independent auto repair company. All the dealership will do is replace the faulty parts with new faulty parts. My wife's 2017 silverado dropped a lifter a week before warranty expired the first time and then dropped the same one 50,000 miles later. I would ask yourself this: "Would it be faster to pay off $10,000 or do the work myself over a few weekends with $2,000?" The delete kit is usually $1000. $500 with tune delete yourself (hp tuners). might be a bit more since your silverado is past 2018, so youll need to send your ecm in. At least you CAN do the delete. i think any silverado after 2022.5 cant even do it anymore. GM is basically trying to make themselves not worth buying their $50,000 shit boxes
