NHTSA Complaint #11643643 — 2023 CADILLAC ESCALADE

The vehicle has approx. 28,000 miles on the odometer. Always serviced at Cadillac on a regular maintenance interval called for by the vehicle and manufacturer. At highway speeds, the vehicle lost all power and came to a stop in moving lanes of traffic putting my family at risk of being rear-ended on a highway at highway speeds (greater than 65 mph). The vehicle was later towed by OnStar / roadside assistance. The Cadillac dealership that received the Escalade determined this was a failed motor. The Service Advisor at the Cadillac dealership mentioned this was a common issue on L87 blocks / engines. They've already seen a few at their dealership and GM had confirmed to them this is a known issue (motor failure on the 6.2 liter V8 L87s). There were no warning lights or other symptoms leading up to the motor failure.
