2015 CHEVROLET TAHOE Complaints

Trailer brake system warning light keeps coming on, over 64 times in less then a 2 hour period, and I"m not even towing or using the trailer brake. It's very annoying, loud and can cause a crash as you immediately look down to see why the beeps are coming for

Service light saying: “Service Trailer Breaking System” It’s happening randomly and driving me nuts.

Trailer brake system error keeps showing. And not towing anything or using trailer brakes. Incredibly annoying

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.

Truck doesn't want to brake have to put both feet on pedal. Almost hit a car in the drop off line this morning at school. When braking it skips a beat and I have to press hard to try to stop it. It scared me because there's no warning lights, it just happened out of nowhere and was afraid to have an accident home very scary. No it has not been inspected by anyone yet. Yes its available for inspection anytime as I wont be driving till I figure out the problem to avoid a serious accident.

While in reverse, at a slow speed, my vehicle still rolls while pressing the brake. I almost hit my daughter’s dance studio. It’s happened many times now and after checking, there is a recall on the software but not the part to fix this. Apparently the software doesn’t fix it because my vehicle software has been updated. I can’t help but think I could’ve backed into a child at her dance studio. Very dangerous for my family and others. Also it’s frustrating to not feel safe driving.

On 10-9-2021 was driving slowly 5-10 MPH in a parking lot and pressed brake and the brake pedal was very hard to press down. Had to really press it hard to stop the 2015 Tahoe LTZ. Had the Tahoe towed to Firestone and they said it was the vacuum pump. Wanted to make sure there was not a recall on the vacuum pump.

Cost is $3600 and he says all parts are on backorder as this is a common failure. The ride is so firm that the car leaves the ground when riding over bumpy roads.
