NHTSA Complaint #11539855 — 2016 CHEVROLET TAHOE

I noticed out of the blue that the Tahoe was down-shifting hard and making a slight whining noise. I brought the vehicle to Supreme Chevrolet in Gonzales for them to diagnose the problem. I was absolutely shocked when they told me that my transmission would need to be replaced. This 2017 Tahoe has only one owner and has not been used for towing, I bring the vehicle to the dealership for regular maintenance. the vehicle only has 127,612 miles. This problem is a huge safety concern because the vehicle could just stop and will not be drivable while driving. This is very dangerous! I have seen hundreds of complaints regarding this same problem on the same make, model, and year. Something needs to be done fast to ensure the safety of the driver and passengers.
