This is the date I first took the vehicle to a dealership. The Transmission has performed poorly and the wiper would not work at all and it was not a fuse problem. Transmission finally failed and had to be replaced (6/25) but car is in a dealership for the 3rd time for windshield wipers. They do not work so car is dangerous. You leave home with no rain and then there is rain and wipers sometimes worked, most of the times they did not. On 6/25 they would not address the issue as wipers worked in High speed (but only on high speed). 3 months later they did not work at all. It did not rain in LA so not concerned, but now it is. This is a serious system design flaw. The replaced complete wiper blade system, but The relays on the bottom of the fuse box control the wiper blades. I have the Z71 off-road package as I drive off-road and in snow conditions. This car was designed poorly as this is a 4x4 vehicle and moister should not effect the electrical system nor a safety device like the windshield wipers. This is a potential recall issue to properly fix the problem. Sadly the majority of vehicle owns just drive on the highway, but others have reported windshield wiper failures.

I purchased my 2019 Tahoe 12/4/2018 and it is a 2019. I have only 9900 miles on the vehicle. In a parking lot my vehicle would not start correctly it was weak but eventually did start. THEN a message appeared and said Service Trailer Brake System. I drove to Starling Chevrolet Mt. Pleasant, SC and they diagnosed it as a module that is going to cost me 1,227.00 . I have never used a trailer. It is only 8 months over the warranty per the dealer. I looked on line and found numerous owners have had this same Service Trailer Brake System service issue.

The power steering failed while driving and we had our baby in the car. We had to make quick adjustment to our driving. We made it home bit very difficultly. I believe there is a problem with the control module because I was able to get it working again but almost immediately it faults out again.

Sudden and unexpected loss of power steering several times. In all cases, the loss of power steering has happened when starting the car. Turning the ignition off and immediately on again did not resolve the issue. Turning the ignition off and letting the car sit for 10 minutes before re-starting the car appeared to resolve the issue. The vehicle has been inspected several times by the service department of Mayer Chevrolet in St. Petersburg, Florida, who has been unable to replicate the issue and therefore has responded that they are unable to resolve the issue. GM has issued a recall for the same issue that has been identified on the 2021 Chevrolet Tahoe and other related GM vehicles, recognizing there is an issue, but no recall exists for the 2019 Tahoe. Issue continues to happen every few months.
