Chevrolet Equinox spongy pedal problems

Filed Oct 3, 2026 · Brakes · WI

While driving my 2019 Chevrolet Equinox, the brake pedal suddenly became extremely hard to press while the vehicle was being driven. The problem occurred unexpectedly while the driver was slowing down. Significantly more force than normal was required to press the brake pedal, which made it difficult to slow and stop the vehicle safely. The suspected component/system is the brake assist system, potentially the brake booster or vacuum system, but the exact cause is UNKNOWN at this time. The vehicle is available for inspection upon request. This created a significant safety risk because the braking system suddenly required substantially increased pedal force while the vehicle was in motion. We were able to get the vehicle stopped and did not continue driving it because of the safety concern. The problem has NOT yet been confirmed or diagnosed by a dealer or independent repair facility. The vehicle has not yet been inspected by the manufacturer, police, or an insurance representative. The check-engine warning light came on AFTER the hard brake pedal problem occurred. There were no known warning symptoms immediately before the brake problem occurred. The brake issue appeared suddenly and unexpectedly while driving. At this time, the exact component that failed is UNKNOWN. Our best assessment is that there may be a problem with the brake booster, vacuum supply, or another component responsible for brake assist.

While I was getting off the freeway, my vehicle displayed the “Service Brake Assist” warning. When I attempted to brake, the brake pedal became extremely hard and would not respond normally. The vehicle would not stop normally when I pressed the brake pedal. I was almost involved in a crash because I could not brake as expected. I had to use the emergency parking brake to help bring the vehicle to a stop and avoid a collision. Component/system: The exact failed component is UNKNOWN. Based on the “Service Brake Assist” warning and the extremely hard brake pedal, I am concerned there may be a problem with the brake-assist system, vacuum system/vacuum pump, brake booster, or related components. The vehicle is available for inspection upon request. Safety risk: This created a serious safety hazard because I temporarily could not stop the vehicle normally while exiting a freeway. I was almost involved in a crash and had to use the emergency parking brake to help stop the vehicle. Dealer/service confirmation: UNKNOWN at this time. The problem has not yet been confirmed by a dealer or independent repair facility. Manufacturer/police/insurance inspection: UNKNOWN/No inspection has been performed by the manufacturer, police, or insurance representative at this time. Warning/message: The vehicle displayed “Service Brake Assist.” The warning appeared before/during the braking problem. At the same time, the brake pedal became extremely hard and difficult to press normally. I am requesting that the federal safety agency investigate this incident along with other complaints involving 2018 Chevrolet Equinox vehicles experiencing “Service Brake Assist,” hard brake pedals, loss of brake assistance, and suspected vacuum-pump/brake-assist failures. I am concerned that this may be a safety-related defect that could cause a loss of braking assistance and increase the risk of a crash. I request that the federal safety agency determine whether further investigation or a safety recall is warranted.

Hard brake pedal and Service Assist message. This issue was recalled for trucks and larger SUVs but not the Equinox. This is a known safety issue to Chevrolet, making my vehicle undrivable until I can come up with the $1,500 to have it towed and repaired.

To Whom It May Concern, I am submitting this formal complaint regarding my 2019 Chevrolet Equinox and the repeated failure of its brake vacuum pump. This is not an isolated repair issue. I have had the brake vacuum pump replaced or repaired three separate times, and each failure has placed my safety, and the safety of others, at serious risk. The first failure was the most terrifying. While driving approximately 65 miles per hour on my way to work, I suddenly applied the brakes and discovered that I had almost no braking assistance. The brake pedal became extremely hard, and the vehicle failed to slow down as expected. I was fortunate that traffic conditions allowed me to avoid a catastrophic accident. Had another vehicle stopped suddenly in front of me, or had a pedestrian entered the roadway, the outcome could have been fatal. Unfortunately, this was not an isolated event. The brake vacuum pump has failed two additional times, resulting in similar symptoms, including the sudden loss of brake assist and an extremely hard brake pedal. Each occurrence has left me questioning whether my vehicle is safe to operate. I recently learned that General Motors is facing a proposed nationwide class action lawsuit alleging that certain Chevrolet Equinox vehicles suffer from a defective brake vacuum pump that can fail without warning. According to the lawsuit, this defect causes a sudden loss of power brake assist, significantly increasing stopping distances and creating a serious safety hazard. The lawsuit also alleges that GM was aware of brake vacuum pump issues through technical service bulletins and customer complaints dating back several years. My personal experience mirrors these allegations exactly. The failures on my vehicle occurred without warning and created an immediate safety emergency. The fact that I have experienced this same dangerous failure three separate times strongly suggests that replacing the component alone has not corrected the underlying defect.

I was driving in GA and my low engine power light came on and I lost complete ability to brake. The brake pedal was hard and would not go down. I towed my car to Jim Ellis Chevrolet in Atlanta. They called a few days later and told me I needed extensive engine repairs that would cost over $5,000 but GM would take care of some of it. I paid $1980.00. I went to pick up my car and was nervous because I lost brakes on a highway and was afraid. I asked them if they were sure everything was repaired and I would be safe and they told me it was tested extensively and driven and all was good. I drove around 2 hours after leaving and my engine light came on and my brakes failed again going 70 miles an hour surrounded by semis. I called Jim Ellis and they told me to tow it to Walter Jackson who told me it was a vacuum pump that they would have had to remove during the repairs. In addition there is a class action against GM about these pumps for my year and make of car. I have asked for a refund from Jim Ellis contacting ownership, GM, Service Team and no one will respond to my calls or emails. I filed a customer complaint with GM and they are accepting zero responsibility as well. I paid thousands of dollars between both repairs and rental cars and the least I would like for them putting my life and others around me at risk on a freeway is my money back.

I was driving to work, when I got off the exit I stopped at Sheetz. When I got back in the car my brake pedal was stiff as a rock, and there was oil on the ground. A friend of mine does mechanic work so I called him and he said it sounds like the vacuum pump. I had the car towed to his garage, the tow costed me $400 which was very cheap considering where I was located. When I got it to the garage he confirmed that it was the vacuum pump and we removed several pieces of metal from inside the engine. I now have my car at the Chevy dealership in Chippewa PA. They told me to be $180 a diagnose it, well they just called me a little bit ago and said it's going to be another $900 to take everything apart and to truly diagnose it. I'm finding out now that GM has known about the failing vacuum pumps and they kept producing them anyways. I see there's a class action lawsuit taking place, and I am not very happy. My life was put at risk. And now I'm expected to be stuck paying this huge bill?

Driving down a curvey road and my brake pedal was hard without no warning or indication. Almost was hit head on because of this. Looks like the Vacuum Pump Seal failed and I lost all of my engine oil, which caused that to happen.

I was driving just got off the freeway and went to hit the brakes and the brake pedal was hard as a rock I had to use force to slow down to safely get over from the left lane to the right lane to get into a parking lot was a pretty scary experience, called AAA had it towed to the dealer they said the vacuum pump failed which I suspected because of the other complaints regarding the same thing, there was no recalls on my car dealer fixed it under warranty and they said there was no damage to the camshaft. The dealer was amazing and would reccamend them, I also had to pay 100 deductible. As others have stated theres a recall on the vacuum pumps but certain Vin #s are not included. Gm needs to included all Vin #s for the equinox in the recall whats it gonna take somebody to get killed!
