NHTSA Complaint #11650969 — 2020 GMC SIERRA 1500

At 59000 miles my lifters were rebuilt on the 6.2 liter engine because of a failure in the 1 and 3 piston. Gm paid for the repairs and then At 79000 miles the motor completely blew resulting in complete failure and seizing the motor and heavy metal chips were reportedly found in oil pan. Gm claimed it was a result of me not doing regular oil changes however I suffer from OCD and I am automotive engineer and my oil was changed early in most cases with my truck. Gm will not take responsibility and at the time they wanted $16k to fix my truck. I was going through a very tumultuous divorce and had to pay atty $34k for that wnd could not pay $16k for a new engine resulting in me having to give my truck back to bank and I have not been able to buy a truck or vehicle since then as it ruined my once perfect credit of 820. It’s changed my life forever and GM should take responsibility. I will never buy another GM product again and my father worked for them my whole life and my family only drove their products.
