From 2015-2024 suburbans have transmission and engine failures or issues. I’ve been told due to plastic parts in the transmission that is the big problem. My transmission has started messing up and I have not been the only one who has had issues. Chevrolet should be made to recall Suburbans and Tahoes 2015-2024 to place new engines and transmission when issues start for free. It is awful that it has not been made aware to the nhtsa to push this to happen sooner. Especially when the vehicle pulls no codes or lights or even gives you a warning before complete failure happens. People can get serious injured or killed if complete failure happened on a major highway or interstate.

I keep getting a brake assist message on my dash. If I am braking at a slow speed, the brakes get so hard to press, and eventually will not let me stop unless I press the brake as hard as I can to the floor. An example, when I am dropping up and picking up my children from school, the brake will vibrate and gets harder to press with each time. With the stop and go in the school line by the time I get to the front to pick up my child it's almost impossible to stop. I have almost rear ended several vehicles going 2 mph because my brakes won't work. Same with pulling and parking into a parking lot space. I am reading there is a recall on some models but my VIN didn't pull up an active recall.

While driving the vehicle on a freeway ramp at speed A warning light came on that said service Trailer breaking And the power steering turned off. Causing the vehicle to be very difficult to control at highway speed. Having a secondary auxiliary system turn off Your power steering at speed Is a serious safety hazard and design issue.

While driving at low speed, the brakes did not engage while being pressed with much force.

When ignition Suv, a gas leak starts coming out of the bottom of the gas tank Strong smell of gas as well. Large amount of gas is seen. Lose of power when driving. Fuel feed hose is seems to be the problem. This may cause a fire or explosion. Putting in risk my family.
