NHTSA Complaint #11702386 — 2025 CHEVROLET TAHOE

My 2025 Chevrolet Tahoe Z71 3.0L LZO Duramax with approx. 3,380 miles experienced a sudden and complete engine failure while towing my camper on the interstate at night, in the rain, while traveling alone 375 miles from home. The vehicle lost power, displayed warnings, and became inoperable, forcing me onto the shoulder in unsafe conditions. The engine has been diagnosed as requiring full replacement due to a defective crank end play / thrust bearing, under Technical Service Bulletin (TSB) 25-NA-307. This is a significant safety concern for a new vehicle and could have caused a crash. GM has multiple documented issues with this model year, and the car has also experienced unresolved infotainment defects, as outlined in TSB #PIT6393F. Requesting NHTSA to investigate a potential safety defect.
