It's only a matter of time and it will happen again. My 2021 Silverado happened at 2990 miles and 12,000 miles. Their policy was to fix the 4 on the side it broke on, so you got screwed there. Now their policy is under 6k or 8k miles like us, you fix all 8. So we both got screwed. Now im reading in the lawsuit that they replaced the lifters with equally defected parts (i'm hoping thats on the older models and older fixes, and their lifter part from March 2021 is a functional working product) otherwise we all got screwed 3x over. To make matters worst, GM customer care is better known as GM i dont give a F about the customer, who won't reimburse jack for your inconveniences or finding you a substitute vehicle while they backorder your parts
