2023 Cadillac Escalade ESV Brakes Problems

My 2023 Cadillac Escalade esv has been at the dealership countless times over the last 2 years with strange engine sounds, acceleration issues, 4 wheel drive would top working and I couldn't make turns without a grinding sound coming from under the hood, check engine light (with no issues seen/heard). The engine recall was "passed" in October even after our concern with the engine sounds and strange things occurring while driving. Last week my wife was driving on a 4 lane 70mph freeway with our son in the car at night and the car said "press start again" and then started slowing down. She could not brake or accelerate. Luckily there was nobody to the right and was able to make just across the line to the side of the road when my car just came to a stop and everything turned off. So she sat there with my son in the dark for an hour barely off the side of the the road before a tow truck driver came but he couldn't even get the car into neutral to get it up onto the truck. My escalade is now at Cadillac of south Charlotte in North Carolina waiting for a new engine. We are scared to drive it even after the "fix" hearing that it can happen again with my kids in the car. GM needs to be forced to buy back or lemon these cars before someone gets seriously injured or worse.

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.
