Cadillac lost its brand loyalty by selling crappy engines that stretch head bolts and cause head gasket failures for too many years.
A $5000 repair.
That, and the infamous transmission code P0741 - torque converter clutch sensor stuck - that takes an entire transmission disassembly to fix with a pennypart. A car that can’t pass smog (or be resold) because of a dash light, is not on the road building brand loyalty, it’s sitting on the side of the road collecting the Dust Of Shame for all to see.
