Brakes Failed problems of the 2016 Chevrolet Tahoe

I am a police fleet manager that has an all chevy Tahoe fleet. In October 2019, I received notification for chevy recall n192268490 and every vehicle in the fleet was taken in for the recall. The recall was to reprogram the brakes, so braking would still be possible even if the brake booster failed. However, the recall did not address the root of the problem, which is a faulty secondary hydraulic brake assist vacuum pump. I was aware of this problem because I had two Tahoes already have a vacuum booster failure, which resulted in an extremely hard brake pedal which would not stop the vehicle. The problem arises during slow speed braking, such as parking lots or slow speed patrol. Less than a week after taking the vehicles to chevy for the recall, an officer was maneuvering slowly in a parking lot. The vehicle experienced an extremely hard brake pedal and the vehicle failed to stop. The officer was able to turn the vehicle, barely avoiding a collision. Obviously, gm's band-aid recall does not fix or even override the problem. The vehicle was taken back to the dealership, where the service providers agreed the recall was a placebo and there is an issue with the vacuum booster. As per a recent letter from gm, they have given an extended warranty on the vacuum pump, for free replacement. So, obviously they know there is a problem. The liability placed on municipalities, who have no other choice but to use their fleet vehicles with known braking issues, is an unfair burden and risk. Gm needs to recall and replace the vacuum boosters!.

Brake failure/ hard brake required to stop vehicle. Vacuum pump failed.

When driving at slow speeds as in a parking lot the brakes fail to stop truck. This happened three times with in a 30 minute time period.

We took a family vacation to NY and almost died because our brakes went out. If you research 100's of people have had their 2016 Tahoe brake pump fail. I am also experience my car jerking. I am beyond myself that a recall hasn't been issued because I am getting ready to go pay for a part that is faulty. You want to make this recall fast or people will die. You cannot have your brakes go out like that!! I didn't spend $50k on a cash less than 2 years ago for my family to die.

Brakes failed to engage on the vehicle when pressure applied. Occurred multiple times. Gm fails to acknowledge this as a known and widespread issue, yet with a simple google search, you can see it has affected numerous people and vehicles. Sounds like a recall should have been issued by now but yet there are none.

Brakes failed 3 times, once pulling into parking space, I rolled down a step driveway into street across street and into neighbors yard and once when a tech from dealership was test driving it, he almost hit the building. The vehicle was in motion each incident.

At slow speeds brake hits the bottom and vehicle doesn't stop. Dealer admits brake vacuum failure.

Tl the contact owns a 2016 Chevrolet Tahoe. The contact stated that the brakes did not work while driving at slow speeds. Obx Chevrolet Buick (6166 n c croatan hwy, kitty hawk, nc 27949, (252) 429-5552) diagnosed that the brake boosters failed. The manufacturer stated that the vehicle was not included in a recall. The failure mileage was 20,000.
