When reversing applying more pressure to the brakes is required than the normal amount. The SUV seems like it doesn't want to come to a complete stop and the brakes are failing.

Due to the excessive braking necessary and the uneven braking that this vehicle has been recalled twice since Sept. 2019, I have been experiencing excessive and uneven brake and tire wear. I have told the dealer multiple times since leasing this vehicle that it did not ride right and the steering wheel would shake every time I used the brakes. It always feels like I have to slam the brakes to even slow down. They fixed one recall and do not yet have the fix for my model year, for the second. The dealer has notes that I needed brake repair at 29,000 miles, but they did not inform me. I brought the car back 3 times since then, noting the exact same thing. At 36,000 miles they told me I am now down to the rotors and the pads and rotors need replacement due to uneven wear. I expressed concern due to the recalls and due to the fact that I have been telling them repeatedly about the driveability of this vehicle, I firmly stand that this is a direct product of the issue from the two recalls. The dealer tried to use scare tactics. I opened a case with Chevy and I am getting no assistance. I am fearful in this car. I am going to get the brakes and tires done because my kids are in this vehicle, but what about after that, it will just keep happening because the on issue is not fixed and the other is not properly fixed. They do not seem to want to stand behind the product and I am guessing will not care when god forbid someone or someone's family is killed.

This vehicle keeps having key fob, electrical issues, tire service maintenance issues, and now engine issues related to the key fob. The key fob keeps saying it is not detected. Recently, while driving on road at about 48 mph, key fob notification came on dashboard saying key fob was not detected, engine shut off and car had to be restarted again using fob box inside glove compartment, this was particularly alarming. The key fob has had batteries replaced and they work because the car will remote start and have tried batteries in other items. The fob does not however let you unlock the car or finish starting it out of the remote start once you get into the car and try to start it, the car tells you it cannot detect the remote. The car has had numerous key fob issues and has been taken into local Chevrolet dealer who cannot find issue. The car has also had 142 hard braking events since April 2019 to November 2019 according to on star reports. The tire service monitor keeps flashing that there are issues with tires. The rear wiper would not shut itself off even though button was in off position. All of these issues have not been able to be repaired at the Chevy dealer. This car is going back in for service 11/18/19 for these issues again. Not sure what the outcome will be until after this appointment. My guess is that it is some kind of electronic circuitry problem(s) but unfortunately the dealer says they cannot find any issue(s) or problem(s) until it completely shuts down. These events are ongoing and have been occurring intermittently since November 2018. All I can provide is photos of the dashboard showing what it relates to me unfortunately I have no documentation of engine shutting off only a photo of what dashboard showed when it happened.

On March 21, 2019 I was in an automobile accident due to brake issues. I was at a red light in the left turn lane around the corner from my house. There were 3 or 4 cars in front of me to turn left. Light turned green, everyone proceeded. The car in front of me passed the cross walk at the intersection, she slammed on her brakes and decided not to proceed. I saw her making a sudden stop, I stepped on the brake. Since we weren't going very fast, my expectation was for my car to stop. I found that the brake pedal seemed to be more difficult to push. Instead the harder I pressed on the brake the more I realized I was about to hit the car in front of me. At that point I felt like I had to slam on my brakes. Things were happening so fast. After my vehicle bumped the car in front of me, I asked the girl to pull off the road so we wouldn't block traffic. I called the police to come out to take a report. She stated that her vehicle already had a hole in the bumper so my vehicle didn't do much damage to her car. We both had our vehicles repaired. Sometime in early to mid may I received a generic letter from GM (dated April 2019) discussing the fact that there may be a condition with the 2017 Suburban may have a condition where customers may experienced increased brake pedal effort. I contact GM after studying up on this issue and filed a complaint. I recd a case #. sometime later he contacted me saying my case had been moved to another area. Never heard from anyone called them on June 18. Waited for another call. Finally heard case was being moved to another area and was told it could take 30 days or more. I supplied all they asked for. They sent someone out to retrieve data. Waited and waited. After much effort received an email saying that the accident occurred 5 months ago & the condition may not have been present at that time and declined to assist

I was driving with my son as a passenger.I pulled up to a red light at very low speed from a high school parking lot. It was a red light. 1st car making a left.I came to a complete stop before the crosswalk.after being stoppef for over a minute, I began to release the brake pedal. As I released the brake slightly the brake pedal got very stiff and the car started to shake. No emergency stop/lights/seat vibrate or ABS systems were activated. As the car crept past the crosswalk with the brake being depressed fully, shaking violently. The vehicle ended up 5-8 feet further than when I had stopped prior. I never released the brake enough to even move. After the car stopped shaking my son had looked at me and very scared asked if it was an earthquake. I said no the car had not stopped. He said to me wow that was the same feeling from when our vehicles brakes failed once before and plowed into the vehicle in front of us while my wife was driving. My son was there for both incidents but my wife and I were separate drives for both instances. I then tested the brakes to be operational and continued home. I brought the vehicle to paradise Chevrolet at the first appointment they had available even after I stated it was a safety emergency on a vehicle that had had brake failures in the past. After the first time they replaced the vacuum pump due to failure causing a traffic collision with injuries. Chevrolet inspected the vehicle only to find that this time the vacuum pump was within parameters and brakes work sufficiently after the vacuum update from a year ago.I am now driving the same vehicle based on the inspection from local Chevrolet dealer.I do not feel safe in this vehicle after the vacuum pump being replaced 2 times due to failure and a third time with a failure and no proper replacement.my family is in danger and so are other drivers on the road.

I was at the top of a boat ramp beginning to back up in order to launch our boat when the brake pedal felt hard as a rock, it would not press down. Quickly, I shifted into drive and moved slowly to level ground. The brake pedal remained hard, but stopped when exerting tremendous pressure, aka "standing on the break." I had the vehicle towed to a Chevrolet dealership for repair. The problem was a failed brake assist vacuum pump. Apparently, there is a class action lawsuit against GM for this very problem.

- Marion, OH, USA

Brake pedal became very hard to press and wouldnt stop the vehicle, nearly causing an accident. The service brake assist light came on. I had the code pulled by a local garage. The code said the brake vacuum pump had failed. Vehicle on has 60000 miles.

When driving on highway and when to apply brake pedal was hard and didn't respond I had to slowly pull to the side and the car finally brakes after I literally had to stand on brake pedal. No warning lights brake pedal extremely hard

- Miami, FL, USA

I have had an issue twice with my 2017 Suburban premier 40K miles while at the boat ramp where the brake pedal gives out a bit and I have had to pump the pedal down hard then apply the emergency brake as a backup. I have a small boat which is why I am concerned it may be a brake malfunction. Haven't had an issue while on the road yet but both times in an incline boat ramp. After reading several similar issues like mine on the web I will be calling GM customers service and having my brake system checked again.

We bought this vehicle and immediately had issues with the brakes. When you try and pump the brakes at a slow rate, the brakes harden up and has almost caused several accidents. We called the dealership and they said it was something we had to fix on our own and there was no recall. Looks like this is very common in these cars and you need to be aware. This is an expensive maintenance that has to be fixed.

- Krum, TX, USA

While pumping brakes the brakes at low rates of speed the pedal would get very hard or lock up and the vehicle would not stop and would roll forward almost causing accident. I was able to immediately recreate the event so I drove straight to Chevy dealer where it was diagnosed as internal failure of the braking vacuum pump. I have never in any other vehicle had that issue and this car was bought brand new so I believe it should not be having that issue at just 2 years old. This was also not a cheap fix and am frustrated that it has been reported as common among Chevy cars recently. These vacuum pumps are over and over again malfunctioning for Chevy owners and needs to be recalled it seems to avoid accidents and unnecessary damage

Hi I?M not sure if this will ever be read but this week while traveling across the us (in a blizzard) in my 2017 Chevy Suburban the vacuum pump on my brake assist went out and left me with very little brakes I was luckily enough to get it to a dealership where they replaced the vacuum pump along with the belt that broken because of it. They did say it was a bad design and would most likely go out again. I have 4 children who are in the car with me at all times. I looked online and there is not a recall for my vehicle yet but I read that other people are having the same issues I saved my receipts and I am honestly scared to continue to drive my family around in my car. I hope to get some kind of a reply with some direction to take to get this fixed. Thank you [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).'
