general problems of the 2012 GMC Yukon

I have a 2012 GMC Yukon denali xl that started having transmission "6l80" issues at 120,000 miles. (03/20/2019) beaman GMC stated the transmission was out and needed to be replaced. Of course just out of warranty. So on I spent $6031. 19 to have it replaced/rebuilt, now 80,000 miles later on 3/24/2023 I just had to have it replaced/rebuilt again for the same problem, this time to the tune of $9454. 00. I decided to do some investigative work and found that there is a service bulletin about this transmission that was dated November of 2022. Bulletin # 16-na-338 for a transmission assembly replacement. Also another bulletin (pl0773)dated July 2012 and one dated February 2012 bulletin pi0488a. I can email you copies of these if you would like. There was also a preliminary report/bulletin put out June 6th, 2020 bulletin # pip5175d with all of these bulletins there should have been a recall. Rebuilding what they are already are having issues with is insane. Please consider helping me with this. I feel like there are alot of other people dealing with the same thing and just haven't done their research.

Over the past four months my 2012 Yukon has been hesitating / stopping. I have accelerate into in the intersection and vehicle hesitated almost causing an accident. The check engine light has came on and off numerous times, flashing stabilization and traction switching on and off. I have taken it to the dealership at least five times each time they said there was nothing wrong with my vehicle second to the last time they stated I needed a new fuel pump which they replaced and the problem continued with in two days and continues to this day . The last time I took it in they stated there is an issue with gm vehicles from 2013 to 2017 causing stalling hesitation lack of performance in a setting in high ambient temperatures and there is no fix for it . I believe this is a great safety risk for individuals who live in high climate areas .
