NHTSA Complaint #11696297 — 2023 CHEVROLET TAHOE

2nd Powertrain failure in 4 months in 2023 Tahoe with 6.2L engine. The first being the Camshaft and lifters failing at highway speeds, which was repaired. The second issue the engine seized while on a tollway going approx 70 MPH with my spouse, children, and family in the vehicle. We were able to coast to the shoulder while waiting on a tow truck. Because of the engine being seized, the Tahoe is waiting on the engine to be replaced. While we wait, we were told they have no loaner vehicles and there are no GM rental vehicles available with who they contract through. Having a 2023 leased vehicle fail twice in 4 months with children in the vehicle is unacceptable and brings to question the safety and reliability of the vehicle moving foreward.
