After vehicle has been parked, when put in reverse trying to back out of a parking space the brakes do not activate and barely can get the vehicle stopped.. it has happened multiple times. Feel like I can't get the vehicle stopped even pressing or pumping the beakes!! it's a matter of time before I hit something. Very scary! when I shift it into drive to go forward they work just fine.

Second instance backing into parking space petel went to floor no brakes then petal came up and was extremely hard to press down hitting another vehicle in the process. After a period of time brakes went back to normal operation.

Truck mileage is 48K. Drove about 8 miles to restaurant for dinner and all was normal. Came out of restaurant and started truck in parking garage and steering wheel wouldn't budge without great effort and then only in half inch increments. Took a cab home and and had truck towed to sport Chevrolet for service. Brakes required replacement of the vacuum pump under warranty. The steering rack had to be replaced for $2880 not under warranty. Issue is sudden total steering rack failure with no graceful degradation. If it had happen at highway speed I wouldn't be here to report the failure.

Brakes felt like they were slipping and the vehicle would continue to roll for a minimum of 5 feet. "service brake assist" message was shown and the brake module was replaced. Vehicle was in motion 24 hours after replacing module on a major highway and "service brake assist" appeared on the dash. Brake pedal was hard and braking system was completely inoperable.

Hi im writing again to report on 2016 Chevy Tahoe vacumm asst failure / defective parts the Tahoe had at the time of the crash 40,475! I had just picked up my vehicle from service at jack schmitt Chevrolet for unrelated issue I was 2 miles from the dealership heading southbound on green mount rd. Approaching a stop light I was slowing down coming up to the light when spider fell between my legs so I attempted to kill it at the same time the collision alert activated and I immediately hit the brakes but the pedal was hard and the SUV was not stopping like I thought it should so I started making evasive action to avoid rear ending the car at the light. I pulled the steering wheel all the way to the right but the SUV kept moving not slowing as it should have and hit rear passenger side back oh the car in front of me causing nominal damage to both vehicles about 12,000 for the Tahoe which I got repaired so I chalk it up as my fault but I kept noticing the SUV on several occasions seemed like it was still moving when it should stopped. Months passed and I was looking up possible causes and on a web site a complaint made by somebody who's Tahoe was doing the same thing that's when I filed a claim with Chevy/GM somewhere around June 20 2018 and spoke monique hill who took my report and months later denied my claim and in the same letter said get your vacum asst serviced and I thought that was strange! anyway I did get it serviced at jack schmitt Chevy in ofallon il 6186252800 and was told the vacuum assist was defective and they had to order the parts to repair also they had to give me a car rental because the 2016 Chevy Tahoe was unsafe for the road and that would be held liable if they let me take it and I'm pissed at that point all this time I could have been killed! I was hurt and hurt for about a year sure back and neck and they just denied denied denied! please help

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

- San Antonio, FL, USA

Experienced spongy/soft pedal and increased stopping distance. Took vehicle to dealer thinking it needed new brakes and was told it needed a new vacuum pump, booster and master cylinder at a cost of $1,400. I was told that this was a known issue with several GM models but the vehicle was 2,500 miles/10 days out of warranty at the time.

At very low speeds, brakes do not work. Backing out of drive, pulling into garage, waiting in traffic on a hill. Push down on breaks and nothing stops. Works fine when at normal speeds. Dealership could not create issue at their site. Has happened 10+ times at home and in parking lots and in traffic jams. Began noticing around 40000 miles. Vehicle at 49000 miles now.

I was driving a 2016 Chevy Tahoe on a residential street. My car lost all control of steering and brakes. While driving the car veered to the right and hit a car, continued on hitting 2 more parked cars, drove thru someone's large hedges, and was seconds away from driving into someone's house but was stopped when I hit the 2 parked cars in the driveway. My airbag also did not deploy. Two cars involved were totaled. Again, I had no control over the steering or the brakes. Thank god I'm alive and I didn't kill anyone.

The contact owns a 2016 Chevrolet Tahoe. While driving at low speeds, the brake pedal was depressed, but failed to operate as intended. The vehicle was taken to heinrich Chevrolet (located at 5775 S transit rd, lockport, NY 14094, (716)-514-4134) where it was diagnosed that there was an internal opening in the vacuum pump, which caused the failure while braking.

When driving at slow speeds, particularly to park, the brakes did not work. You can put the pedal to the floor and the vehicle keeps going. This only occurs when at a slower speed, in both drive and reverse. I have taken it to a mechanic and the vacuum pump has to be replaced. This is very dangerous and could have caused an accident, as I almost hit another car because I couldn't stop.

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.
