general problems of the 2020 Chevrolet Equinox - part 2

I received a service brake module warning and then the vehicle became difficult to stop. I was not traveling at typical highway speeds at the time, but I was on the highway. After applying extensive pressure on the brake pedal to stop, the engine lost power and stalled. It was towed to a dealership and determined that vacuum booster pump experienced a catastrophic failure.

I was operating the vehicle when it suddenly shut off in traffic. I attempted to restart the vehicle and received a "reduced engine power" and "service brake assist" message. The vehicle had a clunky noise and failed to restart. Upon inspection at the dealership, I was told that the vacuum pump inside the engine had exploded and sent metal components throughout the engine system. No previous issues or warnings were present prior to this failure. This is a safety issue as the vehicle gave no warning signs of issue and shut off in the flow of traffic with very little ability to brake or steer out of the way.

3/21/2024 my wife received a warning light that the brake fluid was low, upon the husband checking under the hood after cleaning the reservoir cap and opening the cap and looking inside of the reservoir I could see that there was no visible brake fluid in there. Using another car I purchased prestone dot 3 and filled the reservoir it, it took 8 oz out of 12 oz. The 2020 Equinox premier only has 34,500 miles. On 3/23/2024 I have an appointment to bring the vehicle to midas via being towed because of this issue, it is not safe to drive there.

In June of 2023 the brake booster vacuum pump failed, I took it to my regular repair shop and paid for it to be repaired. March 1,2024 I was driving out of town and again the brakes failed, took it to weimar Chevrolet in cumberland MD to once again after less than 10,000 miles to be repaired again. Thankfully the dealership coordinated with the original repair shop and was able to do the repair this time at not cost to me(except I had to pay for a rental for 4 days).

The contact owns a 2020 Chevrolet Equinox. The contact stated that the vehicle was designed with two electric parking brakes. The contact stated that while driving at various speeds, the electric parking brake engaged independently. The vehicle was taken to an independent mechanic, where it was diagnosed that the rear brake calipers were defective and needed to be replaced. The vehicle was not repaired. The contact stated while driving 45 mph on a slippery road, the electric parking brake engaged inadvertently, causing the rear wheels to lock, and the vehicle spun. The contact stated that he was able to regain control of the vehicle and drove to the residence at slow speeds. The contact stated that the failure had been recurring increasingly while driving. The contact stated that while investigating the failure online, he learned that it was a common failure that occurred because the electric parking brake was not fully retracted. The dealer was not notified of the failure. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and a case was opened. The failure mileage was approximately 30,000.

Brake assist fail.

I was driving and the “service brake assist” light came on and I then the brake pedal became stiff and so hard to push! I was driving on the expressway and almost couldn’t stop my car. No warning at all. It happened as soon as the light came on.

Hit my brakes and had nothing but a hard pedal no brakes at all! this almost caused a major accident being speed limit is 70 and I could not stop the car. There was no warning light until I shut it off and turned it back on then lights blinked and said brake assist failure then the warning disappeared once again. This is very scary and I cannot believe there were other reports and nothing has been recalled.

Brake control lost with no warning. Friend whom bought same car 2 days after me experienced same scenario around October 2023. I just dropped off my kid and I was coming off the highway! I could have killed others and if happened 20 mins prior my children! I'm a single mom and my kids only have me. There's no way this is coincidence on the same make, model, year! there has to be a faulty brake system that needs addressed before people do die!! I've been without my car for 3 days now and no one has answers!.

The brake system failed without any indication it would do so. The dealership acknowledged the car brake pedal was not able to be moved when attempting to stop the vehicle and the vehicle did not stop by use of the brakes. The Equinox is no longer in my possession and was bought by dick genthe Chevrolet. The safety of myself, my 11 year old daughter and the drivers around me were put at risk due to the brakes locking up with no prior notice or indication this would happen. The brakes locked up as I was exiting the expressway and I had to turn the car on a side street and let it coast in order for it to stop. Gm and dick genthe Chevrolet take no accountability for the incident and instead told me that the car worked well the first four years at least. In January 2024 the check engine light came on and I had it checked in the service department by the manager and the p code that came back was a sensor issue and the service manager said that it was nothing serious and the car was safe and the check engine light would likely go off on its own in two days or so. After the brakes had already failed, a "service brakes" warning message showed in the display and the check engine light came on.

Experienced brake issues in March of 2022, brake pedal became extremely stiff and difficult to use. Bulletin showed an issue with vacuum brake pump and that was replaced with the exact same faulty part. On 12/28/2023 my engine blew in the middle of the road, leaving myself and my children stranded as I could not shift the vehicle out of neutral for quite sometime. The faulty vacuum brake pump caused the cam to break off the shaft- resulting in debris inside the engine.

The contact owns a 2020 Chevrolet Equinox. The contact stated that while driving at slow speeds speed, an abnormal grinding sound coming from the vehicle. There was no warning light illuminated. The contact drove the vehicle to an independent mechanic and was informed that the rear brake calipers had failed and needed to be replaced. The mechanic replaced the rotors and the calipers; however, the contact stated the failure returned while driving at slow speeds. Upon investigation, the contact discovered NHTSA campaign number: 19v704000 (service brakes, hydraulic) and linked the failure to the recall. The manufacturer was notified of the failure and a case was filed. The vehicle was not repaired. The failure mileage was approximately 71,000.

Power train: I purchased a 2020 Chevrolet Equinox LS in January 2023. For the past 4 to 7 months the vehicle has completely lost power in traffic several times and I'm not talking about autostop and start, the battery life was great, with no dead cells at all. The vehicle went dead, absolutely no power source inside or outside the Equinox, the SUV could not be placed in neutral to move it out of traffic, nor would the remote key work. The Equinox remained in this mode for approximately 20 minutes. During each incident, the vehicle displayed no warning signs or check engine symbol on the dashboard display before or after each episode. Fuel/propulsion system: upon placing unleaded fuel in the vehicle and starting up the ignition, the SUV would start vibrating, sputtering, jerking, and popping sounds. Also, while driving the vehicle upon acceleration at times it seems as if fuel isn't reaching the engine. Brakes: service brake assist may illuminate randomly on the dashboard while on the interstate. These issues has placed and caused my family and I to be in great danger. This is my primary vehicle and I purchased this vehicle because I believed in the reliability of the gm Chevrolet brand. Not an accident waiting to happen. Yes, the vehicle has been inspected, but please remember if no check engine light is illuminating on the dashboard the issues can not be assessed properly!.

I was traveling the interstate i90/94 , merged to the exit ramp and found the brake pedal hard and unable to push to brake. I had to slide the car into neutral and use two feet on the brake pedal to slow down enough to make the corner at the end of the off ramp. All due to a faulty vacuum pump. The debris from the exploded vacuum pump were sent through the engine. And after having the car fixed it now uses about a quart of oil every 500 miles. Engine is shot! seriously bad engineering design that will kill someone if it hasn't already. I am 5'11" and weigh 190 lbs. I estimate it took around 200-250 lbs of force to push the pedal to even start to slow. If I hadn't had over 40 years of driving experience, this would have ended in a catastrophic incident.

During the month of November while driving on interstate 35 intexas I attempted to administer my braking system during slowed traffic and they did not respond. The brake pedal became completely stiff and I had to apply incredible pressure to get the vehicle to slow down until I turned on my hazards and rolled to a stop on the shoulder. I did not have any alerts or warnings until I powered the vehicle off and powered back on to find my engine light on and the service brake assist alert on as well. I had it towed for service to which they replaced the vacuum pump, brake booster pressure sensor and brake fluid. Everything seemed to be working fine however a month later the same exact issue occurred. I took it in to the same place for service and had a brake inspection done and was told everything looked good and they were not sure what was wrong other than the ecm and ebcm were now reading codes. The issue is that this is intermittent with no warning and has been incredibly difficult to pinpoint the exact issue. This has also been incredibly pricey trying to chase an issue that appears one day and clears itself the next and lastly this has been terrifyingly frustrating as I do not know if I will have valid brake control or not on each ride. This issue could be life or death and was traumatizing as I had my son and mother in the car with me during the first event.

Faulty brake booster vacuum code on after 60,000 miles.

The vacuum pump has exploded 3 times, twice under warranty and now outside warranty. This time it has taken out the camshaft.

Attempted to start braking while in high traffic. Brake assist came on and prevented the car from braking properly, almost causing a crash on the highway with the car in front. The brakes had to pressed extremely hard and the e brake had to be engaged in order to stop. Since then the brake assist has not turned off and the vehicle is not safe to drive.

Driving and brakes went out with no warning, no sounds, no anything almost causing me to rear end a 16 wheeler in the dead of night and almost causing another passenger to rear end me! no fluids are leaking. Break fluid not low. The brakes will not go to the floor in reverse, neutral, or drive. I had to get a uber and get the car towed back home. Upon research it is apparent that this is a known problem in Chevrolets, specifically the 2020 Equinox model with the vacuum pumps or something randomly going out while driving. This is very dangerous and I could have lost my life or caused someone else to loose their life! I just got my car a few months ago and it says” no unrepaired safety recalls reported” however this is clearly a known defect that was not bought to my attention upon purchasing the car.

2020 chevy Equinox vacuum pump. Impossible to get the part, safety hazard, no accident yet, takes 2 feet to hold peddle down. No chevy dealer will help me, I need to go to work.

The brake assist warning light flashed and the electric components start blinking and the car went in reverse in traffic. The car then turnt off.

Driving on trip to new york and lost the brake assist system halfway there. No alerts or engine lights came on as they should have. Luckily we were coming up to stop light so not going to fast but almost hit car in front of us. We had no warning and this is a known problem with these cars.

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.

Got hit at 40 miles an hour in a parking lot while a running dog came through and it was caotic.

The contact owns a 2020 Chevrolet Equinox. The contact stated that while driving at approximately 55 mph, he depressed the brake however, the vehicle failed to engage. As a result, the contact had to apply pressure and pumped the brake pedal approximately ten to fifteen 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 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 brakes stop working.

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.

The brake vacuum pump went bad while driving the car.

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.

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.

While driving the brake pedal became very hard to press and stopping distance increased greatly. The check engine light and service brake light on the dash became illuminated. After looking online it became apparent that there are a lot of people with Chevrolet vehicles equipped with the 1. 5l engine that had the same problem and the cause was a faulty vacuum pump. I removed the vacuum pump and it has broken pieces that have fallen off of it and are now inside of the engine and will need more engine components removed to have access to remove all of the metal fragments.

I had just exited off of the highway and I was approaching the red light ahead my brakes became hard to push and they did not stop the vehicle. I ran through the red light in sheer panic. Was able to pull into a bank parking lot and when I turned the vehicle off and then back on the "brake assist" notification came up. I called my local chevy service but at that point I was on a trip from fort worth to houston and was halfway in the middle closest to waco. I drove it to the nearest dealership 30 miles. I had to leave the vehicle for 5 days. The diagnoses was no vacuum to brake booster pump. A total of $504. They said pumps are not included in powertrain warranty and I just passed the bumper to bumper warranty. I had to get a hotel for the night. Then get a family member to drive 3 1/2 hours to come get me and my 2 daughters. My main concern is if anybody else had been coming through that intersection when my brakes failed it could have been a really bad accident. I had gone from a 75mph speed limit and was still going 35 mph when they stopped working.

Vehicle intermittent brake catches, lights come sometimes, door locks open and close, engine light comes on and last time system locked completely and could get vehicle into gear. Had to have it towed. Second time into dealer service, now on 4th week and gm factory unable to determine problem and solution.
