I constantly get error messages When the ambient (outside) temperature exceeds 100 degrees. The lane keeping assist, the forward collision sensors, etc. When it gets below freezing, the forward collision sensors, the brake assist and the service indicators go bonkers.

I have never experienced an issue prior to today, no warning lights on, no symptoms. While driving down the highway I had to slow for traffic and my brake pedal would not push down, a terrible noise was heard and it took everything in my body to stop my vehicle. I thought I was going to kill everyone in front of me. Had to swerve to the right to prevent this. I then see the words, -??service brake assist-??. Then the check engine light came on. In researching I see there is a history of brake issues. I haven-??t taken it to a repair shop because it literally just occurred and I can-??t stop shaking to take it or tow

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.

The check engine light comes on for a few days and when on the brakes are stiff and hard to push. When this is also going on the brake assist light will come on while driving and not pushing on brakes. It came on while on highway going 65mph

While driving brakes suddenly became very hard to press. We could not stop our car. We luckily were in a toll plaza and not moving at high speed. This problem was scary, no warning and my family could have been harmed. We had a mechanic come and fix the problem, but this needs to be fixed.

Service Brake Assist warning. Same issue as NHTSA campaign number 20V603 and GM recall N202300860 but no active recalls on this VIN.

- Massillon, OH, USA

I own a 2018 Chevy Equinox. The brakes have now failed 3 times. Dealership confirmed each time it was an issue with the brake vacuum pump. The Equinox has not been included in a recall, yet there are clearly safety issues. GM had numerous cars recalled for this exact same reason. There is a serious safety issue here. I am now without a car again because of a third brake vacuum pump failure. I have not been able to get any assistance from GM or my local Chevy dealership. I now am faced with a bill for repair for almost $2000. It is ridiculous to think that such a serious safety issue would exist and the industry will not acknowledge that it goes far beyond the vehicles they have already recalled. I wonder how many more accidents will happen before this is corrected. To be honest, when I do get my vehicle back I-??m not sure I will drive it. When you lose your breaks 3 times it-??s very difficult to trust. I would like to see this corrected and the Equinox needs to be added. My car has 128,000 miles on it at the time of the third failure. The other two failures were at approximately 60,000 miles and 92,000 miles. Thank you.

When I lift my foot off brake the car Stop/Start feature engage causing lurching jerks forward or roll backwardson hill I fear the roll back on inclines praying vehicles are to close behind and rolling backwards into another vehicle, censors lights take turns coming on each time I lift my foot off the brake pedal. All of the following, service brake assist, service stabilittrak, park brake released, service hill start assist action not working, car locks unlock and relock by themselves. I have had these issues since. These issues have been occurring since around 16,000 miles and keep getting worst everyday. GM claim not to have a fix for these issues. They offered a few thousand to buy back the vehicle claiming drastic depreciation for milage and wear. At that time owed over $25,000 balance for the vehicle. No one stood to benefit but the lemon law attorneys.They did not consider the milage when these issues started and this is my only source of transportation to use which I told the lemon law attorneys. The lemon law attorneys were going to charge their fee from me if GM refused to pay their fees. I told them I felt in my best interest I should wait for GM's recall for this vehicle as I'm sure I wasn't the only consumer that was having these same issues. My problem is my vehicle is becoming dangerous to drive due to the rolling back and, jerking of the steering wheel, engine cutting off, locks unlocking and relocking and unstable steering. These issues were hit and miss now happens every time I drive which is daily. These issues started 2020. Last correspondence with GM they still claim they did not know how to fix these issues. I question why they are making vehicles and are not able to fix these issues. I have given my family a list of these issues because they create a safety hazard and in case I, a passenger or someone in another vehicle is injured or killed due to GM's negligence, lack of concern and greed.

The power booster brake assist vacuum pump, without any warning, failed while exiting the freeway. My wife couldn't stop the vehicle. Replaced unit for $750. Now Fine SCARED the crap out of her. Approximately 84,000 miles. This is a sealed unit. I am a highly skilled machinist and I have made braking components for auto and aircraft and disassembled and reassembled for evaluation to determine cause and to remedy problem. What happened? DEFECTIVE PARTS OR POOR DESIGN. I request all replaced damaged parts so I have the part here. I did my research and have seen this is an ongoing problem with GMC and yet NO recall. HELP!
