My 2022 Chevrolet 1500 Trail boss (L87 V8) with 65,135 was making a clicking noise. I proceeded to make a service appointment with my local Chevrolet dealership on 05/03/2024. As I showed up for my scheduled appointment, I was turned away by the dealership due to lack of staff. I was told by my service advisor that my truck should be fine to drive for a few days till my rescheduled appointment on [XXX]. On my way to the dealership for the newly rescheduled appointment, my truck engine shut off unexpectedly and without any visual indication of engine problems. I had to call a tow company to take my truck to the dealership. Per the dealership’s review, I was told over the phone that my engine had ‘locked up’ and I would have to replace the entire engine. I was a couple thousand miles outside of warranty… the dealership told me there was nothing they could do to assist me with the cost of the new engine. This morning on social media, I saw that NHTSA is doing an investigation of the horrible experience I went through.
