Car Stall problems of the 2015 Cadillac SRX

On Monday, August 5, 2024 when I started the vehicle and began driving to work I noticed upon startup the engine was clearly noticeably louder. It also made a strange bogging downshift type noise when idling. Upon driving, the noise seemed to go in and out but once reaching approximately 40mph the noise got noticeably loud again and the vehicle seemed as though it was having gear shifting issues. I had the transmission fluid flushed and filled costing me $300. This seemed to help but very little. I did research to find recalls on the vehicle and found “special coverage 18029, reference # n172115200”, which is an inoperative purge solenoid. This is a defective part installed by manufacturer. I was unsure if this was the issue with the vehicle however doing research it was very possible. I contacted gm more than once and was stonewalled. All they said was to contact my local Cadillac dealership to have the issue diagnosed and repaired at my cost. They offered no resolution although it’s a defectively installed part by gm at the factory. Engine light came on for the first time Thursday, 01/09/‘25. I used the diagnostic computer tool from autozone and the printed results showed it was in fact the engine variable valve timing solenoid and crankshaft position - camshaft position correlation bank 1 sensor a “code p0016”. The vehicle has been dangerous to drive nearly stalling out or unable to shift smoothly nearly causing an accident several times, as well as loud and giving off dangerous noxious fumes. Gms refusal to fix the vehicle due to their negligence in factory installing a defective and faulty part, as well as the rear passenger side tire pressure sensor monitor (tpsm) shows the unconcern for their customers safety and satisfaction with their product and underscores that seemingly their only concern is their own monetary profits and refusal to amend and resolve dangerous mechanical issues caused by their own doing.
