The brakes have stopped working properly. I have to use my entire force and press the brakes so hard to stop.
The park assist enabled flashed and when I brake it studders or I have to slam on my brakes because my car won’t stop. I see this is a recall on other Tahoes but not mine!.

My truck keeps shutting off and steering locks up.
Vacuum pump and vacuum pump belt replacement. Experiencing increased brake pedal effort, hard brake pedal, and increased stopping distance. Confirmed by an auto shop and mechanic that this is the issue. There was special coverage given by general motors to this vehicle to address this issue that expired in November (but I did not know that this existed). The vehicle has not yet hit 150,000 miles. Request to have my Tahoe special coverage warranty extended to address this issue.
Service trailer brake system message is appearing.
The vacuum pump has failed once again and it was repaired via a recall in 2019.
While driving at low speeds, I am experiencing difficulty with braking. The brake becomes very hard to press down and it takes me longer to stop. I researched this and came across a recall for a vacuum pump issue. I believe this is exactly what is wrong with my vehicle. However, when I input my VIN into the recall website, it says my vehicle is not included in the recall. How can I get this issue covered without having to pay out of pocket (we were quoted over $700). I fear that I may cause an accident if I am unable to stop.
Brakes shutter in reverse. Sometimes don’t work when backing out. Almost as if brakes go limp or no connection.
Keeps saying service trailer brake system and does not stop ringing in the dashboard it’s very distracting while driving .
When trying to brake the Tahoe seems to not want to stop. The Tahoe comes to a rolling stop or like it is in sand trying to stop. It eventually stops but not when you want it to. Happens more at low speeds then high speeds. . No lights have indicated a problem. And doesn’t do it all the time but you as a driver can’t trust the brakes! I have had my mechanic look at it he can’t find a problem because when he drives it the Tahoe won’t do it for him. Hasn’t been in an accident yet.
When I am going slow backing up, it feels like I have no breaks. Also, if I am pulling into a parking place real slow, it feels like I have no breaks and the truck continues to roll.
Went to start my vehicle 10min prior to me taking off. Five min into my drive I felt my Tahoe start to lose power stop shifting. Once I was able to pull over to a safe location put the car into park and put the car back into drive and the car will not move.

On Wednesday, 11/15/23, I was sitting in my vehicle while it was parked and running for several minutes. After a few minutes, the alert chime went off and the message "service trailer brake system" was displayed on the dash notifications. This alert persisted for several minutes. Since this initial incident, the same alert has displayed 3 or 4 more times, but while driving. It repeats persistently, causing a major distraction, blocking my speedometer, and disabling bluetooth features. I nearly wrecked because of the distraction and have not been able to tow my trailer because of the risk of of the trailer brakes not working. I have an appointment scheduled with my mechanic on 11/28/23 to get this repaired, but have recently learned of several incidents of this same alert from other gm vehicle owners. This seems to be a defective wire harness and needs to be recalled as it is unsafe and renders the vehicle useless for many intended purposes.
While driving the breaks failed to work. Then when I started pumping the brakes again it took longer than normal to respond and I had to press really hard. I was only going a few miles per hour in a parking lot. Now 5 days later it's happening all the time. It's also making a click noise when I press the pedal.
While driving I periodically receive a notification on the dash to "service trailer brake system". The message just randomly comes up with an abrupt warning noise which is a distraction and startles you until it goes away. I don't tow anything with the vehicle. The notification happens about once a month when driving and eventually goes away after a few minutes. I do mostly interstate driving and when the warning comes up, it startles you and you feel the need to pull over immediately. The notification noise is loud and a distraction. I will be taking it to a Chevrolet dealership. I have an appointment late August. This has been going on periodically for months.
In approximately December of 2015, we purchased a 2015 chevy Tahoe lt from carr Chevrolet. We chose gm for the reputation, under the belief if we took care of our vehicle and had it maintained by the dealer, it would last 12-15 years. This was not our experience. Three years after we purchased the vehicle, the engine died. We were assured this was an anomaly and gm replaced at "no cost", as it was a "manufacturing error". Carr service convinced me it was “great”, as now my vehicle would last even longer. I did not question and blindly trusted those I viewed as trained, skilled professionals. Fast forward to present time, my vehicle is 7 years old (90,000 mi) and never missed a single service. Out of the blue, the transmission dies. I was initially told this is “normal" and “happens” to a tune of $8400 plus maintenance and other wear and tear for a total of $10,000+. This did not sit well with me and I questioned the validity. I requested that carr give me a quote to buy back the car and they initially refused to give decent price. I contacted gm to complain. After many more days, I was contacted and offered that gm and carr would carry 70% of the cost of the transmission. I agreed with intent to sell/trade on my own. After many weeks, I picked up my Tahoe and paid $3,400 and headed back to lake oswego. As I entered downtown lake oswego on a slight hill, coming to a 4 way stop, my brakes completely failed…. I barely missed careening into the back of a car, as they naturally moved forward. I contacted carr service supervisor, sobbing and shaking after the events and he immediately arranged for a tow. I then contacted the investigator. After many days, the gm investigator response, “it’s fixed free of charge”. I was told it was “known” that these cars “could” have a problem with the brakes, which is why there was an unlimited warranty should it occur. I expressed that I had zero trust in gm, carr or the vehicle and expected to be compensated.
There’s a recall for this exact issue, but my VIN doesn’t fall under it. But the issue is the brakes suddenly felt different while they maneuvering into a parking spot or slowing for a pedestrian. Happens a lot at very low speeds.
Vacuum pump related to the braking system is failing. This has been a repaired recall. The vac umm pump is failing again. It is my understanding this is a common issue with Chevrolet and GMC and is causing accidents.
Difficult to brake at low speeds.
Loss of braking effort. Also described as a hard pedal, requiring increased effort to slow the vehicle.
My taheo keeps giving a warning of trailer break system. That started going off out of no where the first time it start I was almost to where I was going so just turned vehicle off. It stated beeping and giving me the same warning have had my breaks changed thought it would fix the problem. It continues to beep every couple seconds and continues to say trailer break system. Then read the reason this continues to happen is wire harness is defective. It is a safety risk because it is very distracting with the alert chime for the driver.
Service brake assist continues to come on. Brake is hard to push.

Keep getting a message saying trailer system issue. Has occurred over the past few years but recently has shown up more than once about every day. I don’t have a picture at this time but please help with resolving this issue it is very annoying.
My truck is getting "service trailer brake system". The warning continues to pop up causing a safety hazard.
When the vehicle idles for long periods of time in park or drive (standing traffic or sub-5mph traffic) the brakes provide no stopping power. Upong shifting into n, and speeding up idle over 2000 rpm for at least 20 seconds, the "braking/stopping power" goes back to normal. Not being a mechanic, but car familiar, it's as if the solenoid at long idles does not provide adequate assist power to effectively stop the vehicle. This has caused problems in long traffic lines on 95 south of DC heading to richmond when traffic begins moving and suddenly slows there is no braking power unless shifting into idle and rev. It also commonly occurs in snowy traffic when things are moving slow. It also occurs in summer idle situations in parking lots if the car is left running and then attempting to pull away there is no braking power. Frontal collisions are a risk, and generally low speed runs ins. Ive had this checked by chevy dealer/service shops twice and they claim it is not reproducable. There are no warning lights and all recalls have been serviced. This issue occurs at numerous times since owning the vehicle.
I purchased this 2015 Chevrolet Tahoe in 2017. It was a certified pre owned vehicle from a dealership. The vehicle continues to have the warning message of “service trailer brake system”.
Brake petal is hard and you have to punch very hard to stop at slow speed as in a parking lot or traffic. It will scare you because the vehicle doesn’t want to stop when moving at slow speed. Unsure if it does it in reverse or not.
Power steering assist, abs and skid control failed all at once during travel. Also emergency brake light lit up along with these other warnings. Hard to steer. The vehicle has not yet been inspected. Scheduling that now. All dash warning lights lit up along with warning messages just as the failures occurred. Upon restarting the vehicle the failures reset to normal operation. Note: the vehicle had been running and idling in very hot temps ~101.
While driving down the road at random occasions the “service trailer brake system” warning will alert us by dinging multiple time. This continues to happen more and more frequently. It will ding and alert us over and over again. The longest it has occurred was for about an hour straight. I took a couple videos/videos of this happening. After doing some research online every article I found stated that it is a wiring harness issue. It was recommended that we report this to NHTSA. I should add that we are not and have not every pulled a trailer.
