2019 GMC SIERRA 1500 Complaints

I have a loss of power in the motor with engine codes diagnosed by the dealership of P0016, P0017. These are the same codes and symptoms that are included in the 2021 through 2024L 87 6.2 L motor recall. My motor is a 2019 edition but having the exact same issues. I know these are the same motors and is having the same issue. started having loss of power in May 2024 with engine codes coming in September 2025.

My truck has a blue screen that appears randomly on occasion that states service rear view system. This is a major safety concern. And after reading online it is a very common occurrence on 2019-2025 gm pickups. It needs to be recalled and a for sure fix done to prevent from backing into someone or something. I have small children and my biggest fear is running them over while playing in the yard and I rely very much on my rear view/360 camera to make sure this doesn’t happen even after double and triple checking they are no where near danger before stepping in my vehicle.

Engine developed a clicking sound. Took to dealership and was diagnosed with rod and bearing damage requiring an engine replacement. Was fortunate to have inspected before engine failure while driving. No warning before the failure. I believe there is a known issue with the 6.2 L engines.

As I was turning left from a county road to a highway my truck died on me. I was able to push it out of the road with the help of two other motorist. This is the second time in 4 months were my truck broke down due to engine failure. I had the motor repaired the first week in June 2025 for a similar instance. My truck is at the dealership right now awaiting repair because GM will not recognize that my 2019 6.2 L87 engine has the same known defects as other 2019 6.2 L87. This is a safety issue which GM refuses to acknowledge on my vehicle.
