Adaptive Cruise Control problems of the 2017 GMC Acadia

On [xxx] my 2017 Acadia denali started driving poorly and a steering assist reduced message appeared. I had o'reilly scan for error messages and they were: p0128 and p0826-00. The dealership confirmed that they would need to replace the thermostat. The Buick GMC beaverton technician made a video of my vehicle: [xxx] my safety was put at risk due to the risk of my steering going out. My car intermittently was having trouble engaging in driving (it randomly acted like it was not firing, it was "jerking"), I heard my cooling fan come on immediately the next day when started my car to drive it to the GMC dealership. I feared that my car would just die going over a mountain pass without cell coverage. On [xxx] I had the same steering assist reduced message and then replaced my thermostat at 39,228 miles. I will need to replace this again, 37,638 miles later. The GMC service technician mentioned that this is a typical problem for my car, and I have discovered a 2022 Acadia recall for their thermostats. Please extend this recall to include the 2017 Acadia. The component was not inspected by the police or insurance rep (yet), but it was inspected by the GMC dealership and o'reilly veri scan. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

While driving and accelerating multiple light pop up on the dash and car decelerates. The check engine light, parking brake, car stability comes on. The engine shifts down and doesn’t drive correctly. This happened 3 times while driving on the interstate doing the speed limit 55-70mph.
