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
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.
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.
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-??

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.
The contact owns a 2015 Chevrolet Tahoe. The contact stated while attempting to park the vehicle, the brake pedal was difficult to depress and failed to respond. To avoid crashing into the vehicle parked in front of her she crashed into the curb. There were no injuries. There were no warning lights illuminated. The vehicle was towed to the dealer and diagnosed that the vacuum pump needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 7,770.
Trailer brake system chime goes off constantly. Chevy refuses to fix the defective wire harness. It is distracting and I have no idea if my trailer brakes would properly function if i were to tow. We ranch, but have avoided using my vehicle for this reason. This has happened continuously since 2019.
Brake pedal becomes very difficult to press and has nearly caused an accident on numerous occasions. Recall has been issued for other year models of Tahoes as well, but not 2015 yet.
I'm having problems with my brake system. When I'm backing up it will slide like it don't want to stop fully. If I'm at a light and press the brakes frequently it don't want to stop and feels like it slides before coming to a complete stop. On hills it feels like it's harder to keep the SUV stopped without rolling.
I have had my vehicle repaired and reprogrammed in May 2020 for the recall of increased brake effort and then in august of 2021 the brake booster repaired. It is Jan 2022 and I-??m still having difficulty with my brakes almost rear ending or backing into vehicles when parking. This is unsafe. This is a known issue and needs to be resolved. It has been taking me so much effort to stop or it feels as the brakes are slipping not catching.
The trailer brake system alert is going off twice in a row every 45 seconds to one minute. The chiming is highly distracting while driving and seems to be a wiring issue.
After a 7 hour road trip and returning to local stop and go travel in our hometown, the brakes started vibrating and the brake pedal then went hard. It took a severe downward foot thrust to get the vehicle to stop and even then still continued to roll forward a few feet. The brakes remained hard thereafter and not safe to drive- unable to brake at that point. Luckily we were not in traffic at that time or still on our road trip otherwise I am sure there would have been a serious wreck or fatality. Dealership supposedly took care of the recall repair for the vacuum pump previously but apparently their action was not sufficient. What am I supposed to do about it now? Thank you.
Brake assist problems. When stopping/slow braking while being in heavy traffic, or drive thru, the brakes will vibrate and will not come to a complete stop without it rolling, almost into another vehicle. The brake petal will be stiff and the vehicle will continue to roll. This happens a lot, but seems to only happen during stop/start, bumper to bumper situations.
I bought the tahoe from a buy here pay here Its a salvage car from the action The guy who sold it to me said he would fix and never did I took it in to a shop because i almost recked and the transmission i think messed up because of the brakes and steering There is also another car he sold that my friend bought for me to fix because the guy sold it with out airbags
While pulling forward in a drive thru, slowing to stop, the brake pedal started vibrating and became very hard to press. Came within inches of hitting the vehicle in front of me. I drove to an empty parking area afterwards and was able to reproduce the problem several times. This only seems to happen at low speeds. The brake assist warning light comes on each time this occurs. The vehicle has not yet been inspected by manufacturer or mechanic. I'm filing this complaint because this is a major safety issue. This is not an isolated problem to my vehicle as I have seen that many others have filed the same complaint with the 2015 Tahoe.
At low speeds, mainly backing up, the brake pedal goes soft and the vehicle will not stop. As you push harder, the pedal becomes stiff and you feel the ABS activate. I have read online that this is a common problem with the 2015-2016 GM models. Apparently the vacuum pump is the root cause however many have stated if oil is found, the Vacuum Line between the booster and the pump 3. Brake Booster 4. Master Cylinder 5. Vacuum Pump Belt should be changed as well.
I purchased a certified pre- owned 2015 Chevy Tahoe LTZ on November 2, 2021, after one day of driving the Trailer brake system chime came on without any towing. the trailer brakes stopped functioning. the warning message would not stop chiming this was distracting me from driving. this is potential danger situation to me and to other drivers on the road.
