Warnings problems of the 2023 Cadillac Escalade

Unknown. Weather related - rain water incoming on floor board under steering column. Effecting electronics and vehicle driving safety. Vehicle has propulsion control issues as a cause.

I was on the highway while cruising with a speed of 65 to 70 mph all of a sudden vehicle started to shake and lost control speed went down to 20mph on the highway check engine light came up foward collision, stability, traction control and engine died started again stall, had to tow the SUV to the dealership.

On 5/8/2024, at approximately 18,969 miles, the vehicle suffered a sudden and complete loss of engine power while driving on the highway in the rain with my family inside. The engine died, the vehicle lost all propulsion creating an immediate and severe safety hazard. Dealer diagnosis revealed a catastrophic crankshaft main bearing failure, requiring a full engine replacement. Since the engine repair, the vehicle has exhibited persistent intermittent/unintended brake activation. The brakes engage without driver input causing "service brake" messages, excessive and premature brake pad/rotor wear (replaced three times in a matter of months due to heat and dust from repeated activation), grinding, squealing, and locked caliper incidents. The vehicle has been inspected by two Cadillac dealerships without any remedy except replacing warranty parts. An independent mechanic inspected the vehicle and confirmed the issue is likely related to the advanced driver assistance systems. To drive safely, we must disable the collision avoidance and traction control features. This has been reported on multiple repair orders and matches complaints from other 2023-2025 Escalade and gm SUV owners. Total documented downtime since first failure exceeds 160+ calendar days. Problems remained unresolved despite warranty repairs, software updates, recalls, and the l87 engine replacement. The sudden engine failure endangered my family and the ongoing phantom braking creates risk of collision or loss of control, especially at highway speeds. I have been forced to disable critical safety systems to prevent unintended braking. This vehicle is directly affected by the l87 defect that prompted federal recall and investigations. Please include my complaint in the ongoing ea25007 and rq26001 investigations and consider my case in any further actions regarding the adequacy of gm's remedies.
