2023 Cadillac EscaladeRecalls, problems, MPG & safety

“After the recall and switching to the new oil viscosity, the 6.2 ltr engine still quit working! Dealership said bearings seized up and metal shavings were found in the oil.”

“2023 Cadillac Escalade Sport Platinum, VIN [XXX], equipped with the 6.2L L87 V8. The vehicle has a recurring vibration/shudder during steady, light-throttle driving, particularly in the low 30 mph range and again around 53 mph. At approximately 53 mph, the vibration can remain sustained while speed and throttle are held steady and generally stops or improves when I accelerate. The selling Cadillac dealer has repeatedly road-tested the vehicle. The Service Manager personally reproduced the condition and confirmed that the vibration goes away when the vehicle is operated in L9. After further evaluation, the dealer advised me in writing that the vibration was “positively confirmed” to be caused by the cylinder-deactivation process and that it cannot be changed.

OnStar documented recurring warnings and fault codes, including engine/transmission communication faults. The same condition returned after multiple dealership visits and repair attempts, including module resets/reprogramming. At times the check-engine light was no longer illuminated upon arrival, but the dangerous symptoms and OnStar reports had already occurred. An authorized Cadillac dealership blamed alleged aftermarket alarm/tracking equipment and proposed charging approximately $1,900 to remove it. I paid $250 for an independent inspection, which found no such aftermarket equipment and identified the questioned component as a genuine GM part. This incorrect…”
