Service Brakes Problems of Chevrolet Suburban - part 1

The contact owns a 2023 Chevrolet Suburban. The contact stated that while driving 30 mph and depressing the brake pedal, the vehicle failed to stop. The contact shifted into neutral(n) and activated the parking brake to stop the vehicle. Several unknown warning lights were illuminated and the message to “restart the vehicle” was displayed. The vehicle was restarted after several attempts and taken to the residence. The vehicle was then towed to a dealer to be diagnosed; however, the contact was informed that further diagnostic tests were needed to determine the cause of the failure. The manufacturer was notified of the failure. The failure mileage was approximately 57,000.

I experienced a serious brake failure in my 2015 Chevrolet Suburban with 112,500 miles that nearly resulted in a collision. After approximately 90 minutes of driving, I pulled into a parking lot and attempted to stop. Without warning lights or prior symptoms, the brake pedal suddenly became extremely hard to press, and the vehicle nearly failed to stop. I had to stomp on the brake pedal to stop. The same dangerous condition occurred while reversing into a parking space. This created a serious risk of injury to myself and others. The problem appeared primarily at low speeds. After sitting for several hours, the brakes seemed normal again. This intermittent failure is especially dangerous because it occurs without warning. A gm dealership inspected the vehicle and confirmed: "vacuum pump has failed internally causing a stiff pedal at times when pumping brakes. Pump can't build vacuum fast enough to keep up with demand to fill brake booster. " the failed component is available for inspection. I discovered gm special coverage n182202780 addresses this vacuum pump failure. However, gm refused assistance because my vehicle exceeded the 10-year coverage period, despite having only 112,500 miles. In approximately 2020, I had a gm braking safety recall performed. The dealership reprogrammed the vehicle and installed a thicker brake pedal pad rather than replacing the vacuum pump. Despite this previous recall repair, I experienced the dangerous braking condition. I believe this is a serious safety defect, not simply a warranty issue. A critical braking component should not fail without warning, making the vehicle extremely difficult to stop. I request that NHTSA investigate whether the previous recall remedy was adequate and whether gm's special coverage should be expanded into a safety recall regardless of vehicle age.

On August 7, 2026, while driving a rental vehicle in the denver, colorado area with my family, including two young children, the vehicle unexpectedly lost engine power while traveling downhill. The engine shut off, resulting in a significant reduction in brake assistance and creating an extremely dangerous situation. We were able to bring the vehicle to a stop without a collision or injury. After restarting the vehicle, the check-engine light illuminated. The vehicle was no longer considered safe to operate and ultimately required towing by the rental operator. The exact mechanical cause is unknown. I do not know whether the vehicle was subsequently inspected or repaired by a qualified service center, and I do not have access to its diagnostic or maintenance records. After the incident, I discovered that another renter had reported a substantially similar failure involving the same vehicle approximately one week earlier, including engine problems and a check-engine warning. I have since discovered an additional report of an engine-related issue involving this vehicle after my rental. Despite these recurring reports, the vehicle appears to remain available for rental to the public. I am concerned that this vehicle has a recurring, potentially unresolved defect involving engine shutdown or loss of power while driving. Such a failure creates a serious collision risk, particularly on hills, at highway speeds, or in traffic. I request that NHTSA investigate whether this vehicle's repeated failures indicate a broader engine, electrical, or powertrain safety defect. The vehicle remains in the possession or control of the rental operator and may be available for inspection. I can provide supporting documentation of the reported incidents.

When coming to a stop or backing from my inclined driveway the foot brake requires a hard push because it seems to lock up. I couldn't stop when braking. The problem is recurring. It has not been inspected for this recurring problem and no lights or warning signal appears on the dashboard.

When our new mechanic was checking over the car, he and his other mechanic both noticed that there was an increased brake pedal effort even though the brakes were in ok condition. Every time I’ve had the car serviced I have them check the brakes because they feel off. The car stops and the brakes check out with previous mechanics but something doesn’t feel right. Our new mechanic then gave me a recall bulletin from gm n192268490 and said he thinks our car is experiencing this issue. The recall was attached to our VIN when the mechanic pulled it up but when we called the dealer and checked the NHTSA website, my VIN number was apparently not part of the recall. I am writing to state that I believe my car may be experiencing the issue stated in the recall bulletin as per my mechanic’s findings. Attached is a copy of the recall bulletin given to us by our mechanic. Please advise.

Increased brake pedal effort to the point of difficulty to stop or control brake pressure at low speeds. This seems like the same issue reported in safety recall #n192268499-01, but my VIN is outside the covered range. Is the effected range in the recall correct? this has happened intermittently since we purchased the vehicle private party in 2022 with 115. 5k miles on it, but is getting worse.

The vehicle went into limp mode! everything associated with it happened so quickly,no brakes,no steering ,it was terrifying. We got safely to a gas station. We were advised to take it to a certified Chevrolet dealer which we did we had it towed to the certified Chevrolet dealer in charlevoix, michigan. They hooked it up to the diagnostics and said they found absolutely nothing wrong with the vehicle. Very frustrating! after experiencing this terrible incident will never feel safe in this vehicle!.

I was driving to work last Wednesday, and I live on a hill. As I was driving, a "brake failure" alert came over my dash and I lost all control of my brakes!!! I live right off of main street, and my options were only to go straight and into a house, or to turn onto main street and hope no one hits me or that I don't hit another vehicle. I turned and thankfully no one was coming. At the end of that street I was able to coast into an closed down gas station and park the vehicle. I called the dealership I had purchased this vehicle from 10 months prior, and they told me I had to use onstar to have it towed to them. I did that, and they towed it to the dealership. The next day the dealership told me the cause of losing my brakes was due to a software update that was needed!!!!! they charged me $800 for the update & a battery that they said was not holding the charge, which I've never had an issue with. I had purchased an extended warranty with this vehicle and I was told it would be a bumper to bumper warranty as if I had purchased it new (it was 2 years old). The dealership said this was not a critical software update and was not covered under any warranty. I could have been killed or seriously injured or killed or hurt someone else due to my brakes going out due to a software update that was needed!! this is insane!.

The braking system on my 2015 chevy Suburban ltz failed at slow speeds in a parking lot. I have replicated the issue in both forward and reverse. My family's safety was put at risk in that while backing up out of a parking spot the brakes failed completely and I had to push extremely hard on the brake to get the vehicle to stop. That same behavior occurred while pulling forward into a parking spot, almost hitting the car in front of me. I took the vehicle into a Chevrolet dealer today indicating the symptoms and they said there was no recall attached to my VIN. This exact same behavior in my vehicle is described in [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I went to get in my 2023 Suburban this morning to travel to the gym. It started but it would not shift out of park. I looked down and noticed the check engine light was on, the abs light was on, and the park brake light was on with a lock and wrench. I had no issues since I purchased it used in March 2025 and yesterday it was driving fine.

The contact owns a 2024 Chevrolet Suburban. The contact stated that while depressing the accelerator pedal, there was a loud rattling sound coming from the engine. The contact stated that while depressing the brake pedal, the vehicle failed to respond as intended while driving with her grandchildren inside the vehicle. The brake failure warning light was illuminated. The contact stated that the vehicle lost power and coasted and slowed down, and the contact shifted into park(p). The contact stated that the failure had occurred on two separate occasions. A dealer was contacted. The vehicle was taken to a dealer, where it was diagnosed; however, the diagnostic result was unknown. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 16,600.

I pulled on to the road and I heard a loud knocking and my vehicle started skipping and wouldn't go. The lights on the dash lit up and said, "brake failure" and "emergency brake failure" and I had no brakes. I managed to coast into a parking lot. The engine light was on. I turned the vehicle off and waited about 5 minutes and turned it back on, the engine light remained. The first time this happened I was going down the road and the vehicle started sputtering, the emergency brake light came on the dash and the car shut off. It has a rough idle when you start it. I am terrified of this car. I have grandbabies in the car with me, had I been on the highway either time I would have caused a terrible accident. The dealer says they can't get the car to do it so they can't fix anything. It has happened twice so you know it will again.

When driving at low speeds the brakes do not work. The vehicle will stop, but it is very hard to get it to stop. You must push the brake pedal all the way to the floor to get the brakes to work. This does not happen all time it will just happen out of no were, this can be scaring. I looked up to see if our vehicle has any current recalls, which it does not. But on 9/19/2019 we had our vehicle in the shop and they did do a recall at this time. It was increased brake pedal effort. Nhtsa campaign # 19v645000 and this sounds like exactly what was happening. This was done when our vehicle had 60,000 miles on it and at the time it was having no symptoms. We had never had any brake issues at this time. Now our vehicle is having these issues and I feel that this safety issue should be another recall on our vehicle and should be covered and fixed as it sounds like the same issue. Please let me know what can be done about this.

If I pull up to a parking spot and I’m slowly creeping into the spot, say at a popular supermarket, and slowing down the brake pedal stiffens up and it’s almost impossible to press. I feel like my truck may not stop. If I’m on a slight incline and in a line behind another vehicle, I’ve noticed the brake pedal stiffens up then as well. Awhile ago I thought there was a recall for this for my truck and it was something about the vacuum in the brake pedal. This is a super problem. I have five kids and we are on the road a lot. This has been happening a lot but most recently would be today.

The contact owns a 2016 Chevrolet Suburban. The contact stated while driving at approximately 70 mph, the vehicle brakes independently activated. The contact stated there were no warning lights illuminated. The contact pulled off the highway and stopped the vehicle. The vehicle was turned off and restarted and regained braking functionality. The failure was intermittent but occurred at various speeds. The failure occurred mostly while driving up an incline and depressing the accelerator pedal and the independent braking failure would occur. The contact had not taken the vehicle to a dealer or independent mechanic to be diagnosed. The vehicle was not repaired. The contact stated that prior to the failures the vehicle had been taken to a dealer to be repaired under NHTSA campaign number: 19v645000 (service brakes, hydraulic). The manufacturer was not informed of the failure. The failure mileage was approximately 175,000.

My wife was driving the vehicle and was pulling into a parking lot. The brakes failed and would not stop the vehicle. She pressed on the brakes very hard, multiple times, for several seconds, before the vehicle finally came to stop. She then proceeded into a parking spot where the brakes again failed to stop the vehicle promptly. Several lights illuminated and a “system brake failure 43 mph top speed” message appeared, alternating with several other messages appearing. The vehicle is in for service at classic Chevrolet in granbury, texas. They are telling me that they reset the codes and that the codes are not returning. I am extremely concerned that if I pick up the vehicle at this point, the brakes could fail again and cause an accident with serious injury.

No official incident has happened yet, but the brake assist kicks in, yet does not work until it's revving engine to over 4000rpm, which causes a sudden jerk and scary sounds from engine. I have had a few instances where the vehicle did not want to stop almost causing an accident, and these have happened without anything in the car other than my daughter who is 2 and myself. The most recent problem is a weird rattling sound while going uphill. Before this going uphill is extremely sluggish, where I have the gas peddle almost to the floor, but nothing happens other than decrease in speed until it finally, about 30 seconds-1 minute, where it kicks into overdrive. Even then, speed does not increase by more than 5-10 mph depending on the incline. I have not brought it to get looked at yet, as I've seen these issues have been reported by numerous consumers without any recalls being sent out other than the breaking system update.

The brake system had a failure and the vehicle could not be slowed down. The brakes would come and go until I was able to stop. Gm dealership diagnosed it with a failed master cylinder and the part is on national back order.

I have had my cruise control set and my car will slam on the brakes with no vehicles in front of my car or on each side. This has happened multiple times, it doesn’t matter if I am going 40mph or 60+mph. I have taken it in and they say there is nothing they can do for the issue. I’m worried for the safety of myself, my family, and my unborn child. As well as any cars around (behind me potentially) when this happens. I do not want to unintentionally cause an accident.

Often the brake pedal becomes very hard to push and braking is extremely hindered. There is a recall for this issue that has been done but the vehicle is experiencing the exact same problem again. Dealership says that the vehicle time has expired for anything to be done again. Recall was performed only 5 years ago.

A. The emergency brake system, the anti-collision sensor, the vibrating driver's seat alert, the dashboard collision alert lightening. . . . . . All of these gave no alert prior to the collision. B. The failure of the safety devices prevented from me from avoiding a collision that was cause by the other driver (police report available for your peruse) c. They inspected and denied any liability for any failure of their safety devices (and my question to them is if any these are functioning properly as said, then there wouldn't be any collision ) d. Yes, inspected e. There were no waring lamps, no seat vibration, the emergency brake never ceased the car from colliding.

Various times while I was driving my 5 kids have I had an issue with the brakes and having to over compensate to pump brakes to get them to stop in time or at all. Very scary.

I was driving home at highway, I hear noise scrapping noise from uneven pavement and roll over speed bump and a piece of metal like u shape felt off. When I get home, inspected I saw my vehicle fuel tank hagging on one side. For safety to prevent tank to felt off I have to get a strap to secure it the tank to the franme .

1/10/25 complete braking system failure, could no brake, could not use emergency brake. Almost crashed into my garage -chevy service dept. Replaced electronic braking control module 1/24/25 complete braking system failure, could no brake, could not use emergency brake -chevy service dept. Replaced battery 2/1/25 car shaking terribly, my kids screaming we were going to “explode” , car smoking, white smoke coming from exhaust -chevy service dept. States there is an engine issue, they will need to break down and replace parts / repair.

Brake master cylinder failure, took car to chevy after brakes got super hard to push , luckily no accident , felt like no brakes, at the point of failure, brake light, abs light, check engine light all went on ,at some point abs and brake light went off but check engine light stayed on and screen on dash indicated max speed 62 then in a couple of minute screen showed max speed 42 mph , then lights go off except check engine and vehicle works as it should it randomly does this in one day so vehicle was taken in to dealership where they had a hard time figuring out if thats the problem and contacted gm tech support gm and they said with these codes it should be the brake master cylinder, and it would cost me 3000. 00 to fix. On an 80 000. 00 car that's a 2021 with 82,000 miles and they are pretty certain that will fix the problem, I'm pretty sure I don't want to get in an accident at 65 to 70 mph and die I feel this is a huge safety issue and thank god wife and kids weren't in the car considering this is my wife's car to drive the kids around in.

The contact owns a 2016 Chevrolet Suburban. The contact stated while approaching a stop sign and driving at 5 mph, the brake pedal was depressed and failed to respond. The brake service warning light illuminated after the failure. The contact was able to pull to the side, turn off the vehicle, wait a moment, and restart. The failure persisted and progressively worsened. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 100,000.

On October 23, 2024, my 2016 Chevrolet Suburban was stopped in a line of traffic on a downhill. As traffic began to move forward, the brakes failed to hold, despite pressure on the brake pedal. This resulted in a low-speed collision with the vehicle in front, which then impacted another vehicle. Component/system: the braking system failed to engage despite pressure on the brake pedal. The vehicle is a total loss; however, documentation of the damage is available through my insurance company, new jersey manufacturers, claim number 2024-884575, and the police report from the accident scene. Safety risk: this brake failure posed a significant safety risk to my family (who were occupants), and other drivers. The collision caused substantial vehicle damage. Confirmation: the vehicle has not been inspected by a dealer or independent service center due to it being a total loss. It has been inspected by my insurance company. Inspection: the vehicle has been inspected by police at the accident scene and by my insurance company. Warnings: there were no prior warning lamps, messages, or symptoms of brake problems. The vehicle has been consistently maintained by all american Chevrolet with all recommended services performed. This incident raises serious concerns about the vehicle's braking system integrity, especially given its consistent professional maintenance. I request an investigation into this matter.

While driving approximately 70 miles an hour and trying to switch lanes, we got a stabilitrack warning and the car shut off for a second and then came back on. The weather was nice and there was no snow or any other adverse conditions. This happened a couple more times on the ride and then when we tried to turn into a parking spot it shut off completely and we had to restart it. We turned stabilitrack off and the car was ok for a couple of short drives. Then driving late at late and we passed another car the same thing happened. Then when we tried to turn our brights on we got the same message. Then we got a brake assist message and then we got a collision alert. The headlights were flickering the rest of the drive and we couldnt use our brights. We had our 4 children in the car and it was shutting down at high speeds and very scary. I looked up our VIN and it said that the recalls had been worked on but I dont remember this being done. This has never happended before this. Our car would be available for inspection if needed.

Failed break fluid detection.

The check engine light came on at 14k miles indicating there was an emissions error. The brakes squeal and have had to be replaced 3 times since the original purchase in March of 2024. After the third replacement of brakes they still squeal. Even if the car is not braking it makes the noise. The radio shuts on and off constantly. Chevy reported they are aware of the issue but there is no fix at this time. The dealerships reset the radio but the issue persists. I’ve had to park the car because I’m afraid the brake issue is much more than they’re willing to admit.
