2016 Chevrolet Suburban: soft or spongy brake pedal

Filed Feb 16, 2022 · Brakes · MD

While backing up and going forward at a slow speed the car did not stop. The brake pedal was hard and my foot pressure did not help it stop. Terrible feeling. When I turned the vehicle off and back on the brakes seemed to work. This is worrisome. I bought the car used with the car fax stating it had previous minor front end damage. I am concerned this has happened before.

The contact owns a 2016 Chevrolet Suburban. The contact stated that while the vehicle was idle, the vehicle made a choking sound as if the vehicle was about to shut-off. The brake pedal was stiff requiring extra effort than normal for the vehicle to come to a stop. While turning left or right at low speeds, the steering wheel was difficult to turn and made an abnormal hissing sound. The contact stated that there was oil leaking from the front-end of the vehicle. The contact took the vehicle to the dealer who diagnosed that the vacuum pump failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and confirmed that due to the mileage on the vehicle, the vehicle no longer qualified for the special recall related to the failure.

Rollling down my drive way my brakes went out. Very spongy. Pressed multiple times and was able to come to a stop with the help of my front bushes. Master cylinder is full brakes are less than a year. I see online that this is a problem with 2014-2018 chevy trucks and suvs. If my wife was driving she could have been hurt. Heaven forbid my kids where in there too. This is obviously a defect in manufacturing and design and should be remedied by chevy.

The brake pedal is hard to push at low speeds in traffic. It is very difficult to get the car to come to a complete stop especially my wife. Its a shock because it shouldnt take a lot of effort to press the brakes but at low speed you really have too. We have had several near misses with rear ending the vehicle in front because of the difficulty pressing brake.

A few weeks ago, I was backing out of a driveway and my brake pedal became stiff and would not move. My 2016 suburban ltz kept sliding, I stood on the brake even though it wasn't slowing and shifted to drive. I tried again, it happened a couple of times, but I attributed it to the rain. Today, I was in town and backing out of a parking space, the brake pedal stuck again and my suburban kept going back. There were other vehicles parked near me, I put it in drive once again as soon as I could. I drove through town to my next stop and called my husband to tell him what happened. The suburban drove fine through town, I was very cautious and scared. As I was pulling into the parking place of my next stop, the brake pedal did it again. I had already mentally prepared for what to do if this happened again, so this time I mashed my emergency brake, just barely stopping before hitting the car parked in front of me. My husband told me not to drive it, he was coming to get me and our kids, we called chevrolet roadside service. A wrecker came and towed it to a nearby dealership. It will be the middle of next week before they can look at it. Dealership didn't have any courtesy cars, so I am out of pocket for a rental right now, but I don't have a choice. I can't put my children's, mine, or other's lives in danger. We bought this suburban new and it has 36k miles on it. Of course at this point I have no idea what the issue is, so that's why I got online and began researching, after I found the other complaints I figured since this sounds like the same issue, I need to report it.
