2020 Chevrolet Equinox

This vehicle starts glitching after exposure to rain. All of the gauges start going up and down, and every action required message pops up one after the other stating "Fuel Level Low, Shift to Park, Park Assist Off, All Wheel Drive System, Service Power Steering, ESC". The vehicle does this while driving at low to high speeds, even on the highways it has happened, the brakes are hard to push in while this is happening. This puts me and others in high danger if I cannot control the vehicle while driving. I have taken the vehicle in over 6 times to the service department of GM and not one time has anything been done. They have been unsuccessful in duplicating the problem every time I've brought it in even when it is occurring.

When I was driving my vehicle, I came up to a red light and my brake pedal was hard and I could not stop the vehicle. The brakes would not work when I tried to stop. With fast acting and thinking, I was able to pull over to avoid hitting the vehicle in front of me, luckily no other cars were around at that time. Mine and my child's safety were at risk when the vehicle would not stop and we could have been in an accident from the brakes not working. The vehicle is currently at the dealership getting diagnosed. No warning sings, warning lamps, messages or other signs happened before, during, or after the failure of the brakes. The brake pedal was so hard you could not push it down at all.

I was driving home from work, just got off the highway, and when I was about to turn into my apartment complex, i went to push on the brake to slow down, and I noticed I couldn't push down on the brake at all. Luckily, it was later in the evening and no other cars were around at the time of the incident. There was no prior warning that popped up before that. My car didn't stop until I pulled the parking brake and then the "service brake assist" message popped up finally. No accident occurred but I am pretty shaken up considering how different the outcome could have been if I was on the highway for myself and if there was any other car involved. I will be taking it to the dealership in a few days.

I was driving on the highway when suddenly my brakes became stuck and I was unable to stop. I was able to safely maneuver to the side of the highway with the help of quick thinking and my parking brake. However, no warning lights or messages appeared from my car directly prior to the event. Although I was safe, this could have had a fatal outcome for either myself or other drivers on the highway had I not been able to move to the side of the highway quickly. My car is currently at a dealership for the weekend and I am awaiting them opening this week so they will be able to perform a full inspection. A sheriff presented to the scene when this happened as I had my hazard lights on while on the side of the road and he did a visual inspection of the hood of my car as well. I am extremely concerned regarding the unprompted failure of my brake system and lack of warning prior.

The contact owns a 2020 Chevrolet Equinox. The contact stated that while driving at approximately 55 MPH, he depressed the brake pedal however, the vehicle failed to respond. As a result, the contact had to apply pressure and pumped the brake pedal approximately ten to fifteen times before the vehicle stopped. The contact then engaged the parking brake. The vehicle was taken to Tires Plus where it was diagnosed that the brake vacuum pump had exploded and caused damage to the camshaft. The vehicle was not repaired. The dealer was notified of the failure and the contact was scheduled to take the vehicle to the dealer. The manufacturer was notified of the failure and the contact was provided a case number. The failure mileage was approximately 80,000

The P0556 code gets stored when the PCM has detected a problem with the brake booster pressure sensor circuit because of abnormal feedback. Braking distance significantly affected by brake pedal becoming difficult to depress. Cause is the brake booster vacuum pump. Internet reports indicate multiple vehicle types during the late 20-teens and early 2020s. Problems are occurring during or shortly after warranty expiration. This is a very dangerous problem that could cause serious injury.

My brake pedal became hard as a rock requiring all of the leg strength I had to stop vehicle followed by a Brake Booster warning light and an email from OnStar. My concern here is GM eliminated that foot/hand operated emergency/parking brake leaving no backup method to stop in an emergency. Women, for the most part, and inexperienced drivers would not have the strength or knowledge to push on the brake pedal as hard as possible to stop the vehicle. Once they pushed with normal pressure and the vehicle didn't stop there would be an accident. In my case I was traveling at 45 mph in congested multi lane traffic on the inside of four lanes when traffic suddenly stopped leaving me about 2 seconds to react.
