2018 Chevrolet Equinox: soft or spongy brake pedal

Filed Aug 22, 2026 · Brakes · OH

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.

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.

The 2. 1018 Equinox has a brake booster.Vacuum pump on the side of the engine that is a known Failure. The vehicle has very hard brake pedal and barely stops. If left unfixed? The vacuum pump seizes and will blown the engine resulting in full engine replacement. The chevy dealer (local) acknowledges the issue and has stocked the parts shelf at $159. The problem is with multiple makes with the 1.5 l turbo engine. The cost of a new engine is around $5200.

Brake assist light went on, had the brake pads and rotors replaced, light went off. 6 months later the light came back on but this time the brake pedal was hard. I did not drive it after that. After looking online and seeing dozens of people with the same issue, I took a chance and bought the brake booster and had my friend, who is a certified mechanic, replace the part. The old vacuum pump had frozen up and broken along with the gears, which had fallen into the engine, just like what I was seeing all over the Internet. People are getting hurt and lives are at risk, this should have been recalled!!!!

I have a 2018 chevy equinox that I bought brand new back in December of 2018. The vacuum pump failed therefore breaking the camshaft which in turn caused failure to my brakes. I went to stop at a light and my brake pedal was hard and my car skidded to a stop through the light. No warning that anything was wrong nothing. My brakes worked fine up until I went to stop at the next light. Then out of the blue my brake pedal was hard and I had no brakes. I almost got into a severe accident due to the brake failure. Evidently there have been other people this has happened to. Extremely dangerous and unsafe. There have been lawsuits filed against GM for faulty vacuum pump part although they were for the year of 2020. GM needs to take a look at this issue and also install some kind of warning. I get warnings for a tire being a little low you would think they could put a warning in for the brake system!! The warranty is still good on my car do I do not have to pay for the repair. In addition when the camshaft broke it threw pieces of metal into the top part of the engine!!

While driving to Tennessee my brakes went out on the car. The vacuum pump broke into pieces and made braking nearly impossible. Had it repaired and less than a week later the same thing happened coming off the interstate no brakes again on the off ramp. We had to glide to a stop for the brakes to kick in a little past the hard brake pedal. Checked the vacuum pump and again no suction so it’s bad again, not only that it appears that the rear main could be leaking but could be something else all together.
