NHTSA Complaint #11711991 — 2023 CADILLAC ESCALADE ESV

My vehicle experienced a catastrophic engine failure requiring full engine replacement after a recall remedy (oil change with thicker oil) was performed and the vehicle passed the pico test. Engine symptoms became more pronounced after the oil change. In addition, the vehicle has experienced repeated steering system abnormalities requiring multiple repairs, including replacement of airbag-related components and the entire steering column, with abnormal steering noise persisting afterward. The dealership confirmed the engine failure after finding metal debris in the oil and diagnosing a spun thrust bearing, which resulted in a complete engine replacement under warranty. The steering issue was confirmed by dealership technicians, including a lead technician who acknowledged during a ride-along that the steering noise was not normal, despite multiple repair attempts and replacement of the steering column.
