NHTSA Complaint #11657912 — 2020 GMC SIERRA 1500

I have had two engine failures within 2 years of buying a new GMC truck. The first occurred at 24,181 miles whereas i found engine failures is an all to common occurrence with these 5.3 liter engines, failures are wide spread, tons of complaints can be found with a simple internet or youtube search. The second engine failure occurred at 45,517 miles, again with lifer falling apart. Several service bulletins have been issues including reworking vehicles on dealers lots to replace faulty components but in my case i had over 16000 miles so they put the same parts in again and did not touch the other side which then failed two years later at in my case both were attributed collapsed lifter. This is a safety concern, there is no indication this is about to occur. The vehicle loses power, shakes, instrument panel lights up with various different warning lights. If you are passing another vehicle and this occurs it can be frightening as you have no idea what is happening and why you are no longer accelerating if you are passing some vehicles. The value of these vehicles is now also diminished, who wants a GM vehicle with two engine failures with 45k miles? No one, because it more than likely going to keep occurring until the engine is damaged beyond repair.
