Consumer Description

2021 Tahoe Z71 with 70000 miles making a roaring and whining noise on reverse and turning, especially when cold. Took to shop and they changed the rear differential fluid. Now its worse. Needs a whole new rear end. This veicle is 4 years old and does not tow or use four wheel drive. The shop said there has been so many complaints and services on the same issue. Why is there not a recall on this yet? We spend $70,000 and up and expect a more quality vehicle without having to spend $4000 dollars on repairs.
