23 Escalade L87 engine and transmission issue along with rear cross traffic alert emergency breaking. @ 8600k lifter failure (repair) @ 8750k transmission toque converter replacement @10600k spark plug replacement rough idle @17k in for hard down shift transmission valve replacement @21k in for lifter and same transmission down shift issue Service advisor advised that the lifters need to be replaced again and the hard down shift failed to be fully addressed. The upper level from GM advised no remedy could be found until service bulletin could be resolved. No repair work to be performed. To release to customer as is until engine replacement can be performed. So GM is forcing us to take back our vehicle on the road with a failing engine that needs replacement but due to not having enough stock to repair in timely fashion are placing us back on the road until one can become available. This now opens us up for massive catastrophic failure with my family on the road and not to mention others on the highway and public road system. I’m astonished that GM would do this to their customers and jeopardize the safety of their customers and other citizens on the roads. Something has and needs to be done. They are now placing my family and other lives in danger to save money. Vehicle serviced at field’s Cadillac St. Augustine Fl and recently at Randy Mario Cadillac Jacksonville Fl.
