Service Brakes Problems of Chevrolet Suburban - part 2

I purchased my vehicle after the recall 19v-645 regarding the brake pump was issued. My vehicle was a part of that safety recall, and the module was reprogrammed in September 2019 (n192268490-01). The pump has not been previously replaced according to service records. I purchased my vehicle from a dealership in April 2021. I recently (late 2023) started having issues with my brakes, having increased brake pedal effort, a hard brake pedal, and increased stopping distance. I have had the brake assist alert come on several times. The issue happens more frequently at lower speeds. My park assist alert also comes on regularly when applying the brakes. I have taken my vehicle to gm several times regarding the park assist issues, but they have only cleared the computer codes and cannot figure out why they keep coming back, as there is no detectable issues with the system. I have also brought my vehicle in due to the adaptive cruise control, as it has also caused issues while using it. It will often apply brakes if it detects a vehicle in another lane while driving, causing the vehicle to “slam” on the brakes going at high rates of speed (I. E. Driving on the interstate at 80 mph) and has nearly caused accidents, as the vehicle becomes hard to control, and the risk of following vehicles not having the reaction time to avoid a rear-end collision is increased. My particular vehicle does not have an option to switch between regular cruise control, and adaptive cruise control. After talking with gm, they informed me the only way to “fix” the issue is to completely replace the module with an updated module that allows the option to turn off the adaptive cruise control, which is quite costly to the consumer. My vehicle is currently at a gm service department, and has been diagnosed that the brake pump has failed, and needs replaced. They are claiming that it is not covered under the recall. It is not covered under gm’s extended warranty due to mileage restrictions.

The brakes fail on a regular basis!! if when backing out of a parking space you lightly press the brake, slightly release and try to depress the brakes again, power braking appears to be completely gone! the same applies moving forward. Especially in high traffic situations. Cars will move forward slowly. As you release the brakes and start to move but need to reapply as traffic starts to slow again the Suburban requires maximum effort to press the brake pedal and get the vehicle to stop. I’m 240lbs. I have to press hard! my wife has almost rear ended multiple cars due to this issue. It’s typically low speed so the damage would be minimal to another vehicle. However, my wife is a school teacher! kids cross the teacher parking lot all the time! if she lets off her brakes to go and a student walks in front of the Suburban, the results could be catastrophic! this is a major safety issue. I see there is already a recall for many vehicles just like mine!! please tell me why this is not being fixed on ours!! the problem can be reproduced on command. It almost sounds like it’s metal to metal contact when it happens. If you let your foot completely off the brake pedal and roll forward it will revert back to normal operation. It is only when there is a gradual release then reapplication of braking pressure applied to the brake pedal. It has not been taken to the dealership as we can’t afford it at the moment. There are no warning lights currently showing on the vehicle display. This has been happening for quite some time. Probably six months or so but the website does not allow for a range of date. I put today’s date as my wife said she almost rear ended someone again today!!.

The power steering on the vehicle had failed on December 10th, 2023. The sign was displayed on the dashboard for the vehicle. The vehicle was taken to sunrise chevy and stayed with them for a month for repair and they have been unable to repair the issue. They said the rack and pinion had gone bad on this brand new car. This is very dangerous as the safety of myself as well as others on the road are compromised due to faulty steering problems.

The abs and brake lights illuminate as per gm recall 05v379000. This occurs each time the vehicle is driven. I purchased this vehicle on 12/6/2023 from kyle's kars which is a used car dealership in slatington, PA. A warranty was not offered due to the age, however I did purchase a warranty from car shield. This repair would not fall under the warranty guidelines.

Automatic emergency braking system activated at ~77mph. Essentially I had started braking appropriately and at about the same time the aeb system seemed to conclude more breaking was needed. This led to brief loss of vehicle control when brakes completely locked at high rate of speed ~77mph. According to vehicle manual this system should not activate at speed great than 50mph (photo attached). This is dangerous because I could have lost control and/or someone behind me could smash into me. My vehicle does not have adaptive cruise. Vehicle and other systems otherwise work perfectly. As a side note the extreme brake application at high speed caused cargo within the vehicle to slam forward and destroy the windshield, in addition to being a scary event.

The contact owns a 2023 Chevrolet Suburban. The contact stated that while driving at an undisclosed speed, the brake pedal was depressed; however, the vehicle failed to stop immediately. The vehicle was taken to the dealer and was repaired. The contact stated that while driving at an undisclosed speed, the brake pedal was depressed again; however, the vehicle accelerated and failed to stop. The contact also stated that the radio display screen failed to function. The manufacturer was made aware of the failure. The failure mileage was approximately 3,000.

The computer component surged, and the vehicle is available for inspection. The vehicle brake function is lost. Stepping on the brake paddle did not apply brake. Brake function was disabled by the computer. I took the vehicle to dealer, they said it was a component that has high resistance that cause it. But not sure why it has high resistance at that time and the resistance is gone after driver restarted the vehicle. No one else inspected the component beside the dealership. There was no warning at all and this is the first time it happens. Driver was just driving normally and suddenly all the light in the instructment panel started blinking and driver tried to apply brake but nothing happen. Luckly it wasn't rush hour, and driver was able to let the vehicle roll to the freeway exit on ram and use the up ram to slow the vehicle until it almost stop and changed gear to park to stop the vehicle. Driver then restarted the vehicle and the problem is gone.

I keep getting a brake assist message on my dash. If I am braking at a slow speed, the brakes get so hard to press, and eventually will not let me stop unless I press the brake as hard as I can to the floor. An example, when I am dropping up and picking up my children from school, the brake will vibrate and gets harder to press with each time. With the stop and go in the school line by the time I get to the front to pick up my child it's almost impossible to stop. I have almost rear ended several vehicles going 2 mph because my brakes won't work. Same with pulling and parking into a parking lot space. I am reading there is a recall on some models but my VIN didn't pull up an active recall.

The contact owns a 2021 Chevrolet Suburban. The contact stated that while driving at 25 mph, the brake pedal seized while depressed, and the vehicle failed to stop immediately. The check engine warning light was illuminated, and "brake system failure" and another unknown message were displayed. The contact coasted to the shoulder of the road and parked the vehicle before shutting off. The contact's husband then restarted the vehicle and drove to the residence while the vehicle made an abnormal grinding sound when the brake pedal was depressed. The vehicle was taken to the dealer, where it was diagnosed that the master brake cylinder needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 30,000.

While driving at low speed, the brakes did not engage while being pressed with much force.

This vehicle has a non-functioning parking brake. There was a recall in 2004 for 880,000 trucks and SUV's. I have taken it to my garage twice but they cannot fix this problem because it is not fixable.

My car shut off two times while driving. When you google the issue, it auto populates meaning that this is a very common issue with gm. It starts back to 2015 searches as well. Gm needs to recall their Suburbans for their cars turning off while driving which caused me to lose power steering, power brakes and anything that requires electrical.

Service trailer brake system light keeps coming on even after replacing the unit it self.

Braking is diminished when vehicle is moving at slow speed and brake pedal is pressed. The vehicle brake assist engages by pulsing, increasing the braking distance by not stopping the vehicle no matter how hard the brake pedal is pushed. Emergency brake is used to prevent vehicle from colliding. This may be related to NHTSA 19v645.

Vehicle starts dinging with warning - service trailer brake system - and warning - action required steering assist is reduced drive with care - abs light - traction control. Power steering goes out and assumedly abs and traction control stop working.

My rear left tire locks when I’m doing sharp turns and I don’t see any traction control lights come on when that happens.

The vehicle was idle for about 4 months. I took it to a carwash to clean the dust off. Upon returning (abt a 2 mile trip) the brakes failed and steam was coming out from under the hood. I opened the hood and brake fluid was sprayed all over the driver's side of the engine and wheel well. A brake line had rusted through and burst. Fortunately, I made it home carefully because I had noticed the brakes were soft.

Brakes become really hard.

The brakes will sometimes not work properly. When the brake pedal is pressed when parking or coming to a stop, it takes longer for the vehicle to stop. The brake pedal will also vibrate when coming to a stop and "roll" to a stop. We have had our brakes checked twice in the last 3 months at the Chevrolet dealership and they say the brakes are fine. We now had an incident where we were parking in a parking garage and nearly hit the wall in front of us because the brakes did not stop the car properly. We had the vehicle towed to the dealership to have the brakes checked again (February 3rd, 2023). We were afraid to drive it ourselves on the freeway. Since it is the weekend, we have to wait until Monday (2/6/2023) for them to check our vehicle. We are going to let the dealership know what we have found online with the "recall" of certain 2017 Chevrolet Suburbans about a defect in the brake assist and power brake vacuum pump. This has been an ongoing issue we've had since we purchased the vehicle (new purchase in 2017), but it has progressively gotten worse.

I have a 2015 Chevrolet Suburban that had an issue with the brakes not wanting to stop the vehicle at slow speeds. Several times when we pulled into our garage or a parking space the vehicle would want to glide instead of stopping. I've had several parts replaced and am now hoping the problem is fixed. Just picked the car up today from repair shop.

Brakes failed and became hard to press down on it and would not stop vehicle.

Antilock brake system makes it hard to press brakes mostly traveling at lower speed like when I’m parking. Previously had it reprogrammed because of a recall but it continues to have this issue periodically. Now I’m being told I need to replace to brake vacuum?.

Component service brakes, hydraulic:antilock/traction control/electronic limited slip.

The contact owns a 2017 Chevrolet Suburban. The contact stated while driving approximately 5 mph and slowing to park the vehicle at his residence driveway, the brakes failed to function and the vehicle rolled into a large plastic refuse bin. There was minor damage to front left side of the bumper. The contact stated that he buffed out the damage. The contact stated that he did not feel the normal pressure from the brake pedal. The contact placed the vehicle into reverse (r) to back away from the refuse bin and again the brakes failed to function. The contact stated that the "brake assist" light was illuminated. The contact had not taken the vehicle to a local dealer, it was not diagnosed. The contact stated he replaced all four brake pads on his vehicle. The manufacturer had been informed of the failure. The failure mileage was 56,027.

With cruise control activated, at least 10 times since I bought this expensive vehicle the automated emergency braking activated at highway speeds - causing the vehicle to full brake without warning and nearly causing an accident each time (handling risk and risk of being impacted from behind by a following vehicle). I have formally reported this issue to dealers in mn and mt, and they only thing they said was they could not duplicate the condition during brief test rides and this was not a know problem. I personally know this was a known problem and gm did a safety recall for this condition on my15-20 Suburbans. This condition is definitely an unreasonable risk to motor vehicle safety. In additional, the original tires supplied by gm (firestone) failed under normal driving conditions after only about 35,000 miles, and both gm and firestone denied there was any warranty coverage. Since then, new les schwab tires failed at about the same mileage. Something is obviously not right with this vehicle, and this condition is also an unreasonable risk to motor vehicle safety. Finally, last week my front passenger wheel cracked. I have not hit anything significantly hard with that wheel - but it is nonetheless cracked. This is also obviously defective and an unreasonable risk to motor vehicle safety.

My car was acting weird, brake pedal was extremely tough to decompress, speed then was affected, and ultimately the brakes failed.

Issue with power braking system. Has longer than normal stopping distance when braking. Hissing noise coming from power brake pump under the hood. Loses air pressure in brakes very easily. We are afraid to drive this vehicle because this will eventually cause a crash. Mechanic stated this is a known issue with these vehicles of this year/make/model and was on the recall list. This is a known issue that shows reports online my vehicle has issues/recalls on but for some reason my VIN isn't showing the recall. There is no warning message lit up on the dashboard. Mechanic was able to check the obd computer to pull a code of (c0299-00). I have reached out to a Chevrolet dealership who is supposed to be looking into this for me but I wanted to reach out to you guys as well.

We were traveling approximately 30 mph approaching an intersection of a 5 lane road. A vehicle in front t of us had pulled into the turn lane. As we approached the vehicle that was already completely in the other lane, our car suddenly braked to a complete stop even though my foot was only on the accelerator as it is a 40 mph speed zone.

Hard breaking at slow speeds. Risk of accident to pedestrian and to vehicle and to structure. This problem has not been reproduced or confirmed by dealer. This problem has not been inspected by manufacturer or police or insurance no warning lights prior to problem. .

I was driving on the freeway about 65 mph on Saturday June 18. In a sudden instant, there was a message on my dash "brake module failure" and "speed limited to 62 mph". Also warning message that "forward collision warning was off" , etc. The abs light, the "check brakes light", and the check engine light all were on. Also, the power brakes went completely out and to stop I had to press really hard with manual brakes. I don't think a small framed person would have been able to stop and if I had been at a moment where I needed to stop quickly I don't think I would have been able to stop had there been a need to stop quickly. The dealer tells me that the brake master cylinder failed. The car has 43,000 miles and has been well maintained.

When I’m parking the car back and forth brake gets very hard to press and hard to stop and also after turning off trying to start but having hard time because of the brake is not applicable I have to press very hard these are the problems I have thank you.

The contact owns a 2018 Chevrolet Suburban. The contact initially stated that while in reverse(r), the brake pedal became firm as the brake assist message appeared on the instrument panel. The contact stated that she had to stand on the brake pedal to stop the vehicle while in reverse(r). The contact then stated that the failure would occur while driving at various speed. The contact had taken the vehicle to a dealer where the mechanic was eventually able to duplicate the failure. The contact had the vacuum pump replaced; however, the failure recurred. The vehicle was taken back to the dealer where she was then informed that the brake booster needed to be replaced. The manufacturer was notified of the failure and offered to pay a portion towards the cost of the repair. Upon investigation, the contact discovered NHTSA campaign number: 19v645000 (service brakes, hydraulic) which she linked to the failure. The vehicle was not repaired. The failure mileage was 80,000.

Brakes became very hard to apply and the car could not stop quickly. Needed to replace the vacuum booster pump.
