I jinxed myself replying to you.
got a video texted to me from the mechanic showing me the leaks that are causing the random low coolant and check oil at next fueling warning lights. the coolant line to one of the turbos is leaking, and there is oil seepage around the oil filter housing, which to repair is essentially "sealing the entire front of the motor." every hose gets replaced, like 3k worth of repair.
I needed 1 more year out of this car.
meanwhile, the new tires are terrific.
