What owners are reporting 2 most recent
The transmission in my 2024 Chevrolet Blazer is very noisy often making whining and grinding sounds and I experience rough shifting and transmission hesitation during acceleration or gear changes.
Sudden catastrophic drive train failure while driving. Car stopped instantly and was totally immobilized. It had to be dragged onto a flatbed tow truck. It is at dealership now for evaluation.

It's a documented issue but not catastrophic. 5 complaints have been filed. Repairs average $2,500 and most owners catch it before it causes a breakdown.
At what mileage does the powertrain typically fail?
Mileage data is limited for this issue. Owners report failures across a wide range, suggesting cause is more about driving conditions and maintenance than mileage alone.
What does it cost to fix?
Independent shops typically charge around $2,500 for powertrain repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
