general problems of the 2015 Chevrolet Tahoe - part 2

The contact owns a 2015 Chevrolet Tahoe ltz. The contact stated while trying to park the vehicle the brakes got very hard and could not stop. 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 as the vacuum pump needs to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 7,770.

I’m pretty sure it’s the vacuum for the breaks because when I park if I put my foot on the brake multiple times it gets stiff solid. But once I put the rpm’s up the brakes get better. I almost hit a parked car because of this because I couldn’t stop.

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.

“trailer break system” warning keeps popping and makes it very difficult to drive safely!.

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.

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.

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.

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.

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.

The battery power saver light came on then as backing out of driveway I lost power and steering control service brake assist light flashed as well as service stabilitrack and steering assist returned home bc I had five kids in vehicle and couldn’t risk it.

At low rate of speed the brake pedal becomes hard to press when attempting to stop. Vibrating feeling and clicking noise can be heard from brake pedal.

The contact owns a 2015 Chevrolet Tahoe. The contact stated that while driving from a complete stop and while driving at various speeds, the vehicle made an abnormal whining sound. There was no warning light illuminated. The vehicle was taken to the local dealer, where the transmission was replaced. The contact stated that after retrieving the vehicle from the dealer while driving 10-15 mph, the brake pedal was depressed but was significantly firm and failed to respond. The contact drove into a curb and struck a parking sign pole. The air bags did not deploy. The contact stated that the failure exacerbated pre-existing injuries. The dealer was contacted and advised the contact to restart the vehicle and depress the brake pedal to verify whether the brake pedal was operable. The contact followed the dealer's instructions, and the brake pedal responded as needed; however, the vehicle was towed to the residence because the contact was concerned about driving the vehicle. The vehicle was then towed to the dealer, where it was diagnosed and determined that the vacuum pump needed to be replaced. The dealer replaced the vacuum pump; however, the failure recurred while driving. The check engine warning light was illuminated. The vehicle was taken back to the dealer, where it was diagnosed and determined that the lifters had failed. The vehicle was not repaired. The vehicle was taken to a second dealer, midway Chevrolet plainwell auto dealer (381 12th st, plainwell, mi 49080), where it was diagnosed that the fuel pump wires, the transfer case oil and seal, the engine oil coolant hose, the valve cover gasket, and other unknown parts needed to be replaced. Additionally, the dealer determined that the ball joints needed to be replaced, and an alignment needed to be performed. The dealer also determined that the air ride compressor was noisy. The vehicle was not repaired. The vehicle was then taken to a third dealer, heritage Chevrolet, inc. (350 w dickman rd, battle creek, mi 49037), where it was diagnosed with an oil leak.

At low speeds (less than 10 mph) brakes (abs and power assist) have failed when in reverse on slight incline. Most recently (4/20/2021) the same issue occured when moving forward, at approximately 5-7 mph, while on approx 8% downhil grade. The road surface was non-paved, mixed dirt/gravel. This issue occured multiple times, however, during 2 of the occurances the vehicles would not come to a complete stop and was thought to have continued over the edge of road into canyo if not for an extreme choice forward path to navigate thurn. This "road" was the white rim road in canyon lands national park, utah.

Yesterday while driving at a low speed, slowing to a stop, the brakes felt very hard and difficult to press to stop. I continued to drive for the remainder of the day and it seemed to stop fine at higher speeds but slowing out of driveway or into parking lots it was very difficult to stop. Even at stop signs, I had to start hitting the breaks well ahead of the sign in hopes that it actually stopped by the time I got to sign. It seemed to get worse. Called dealer and left message. Called again and service department was closed for the weekend. Likely it will need to be towed to the dealer. I don't think it is safe to drive.

At slow rate of speed, pulling into parking spot or in drive-thru lines, the brake pedal takes effort to push, ticking, clicking and grinding sound and the brake pedal begins to vibrate and very hard to push down to stop the vehicle. I see this has been recalled on other vehicles but not my particular Tahoe ltz VIN# this has been an ongoing issue since September 2019 after the car was purchased.

I pulled into my driveway. . . The engine speed started increasing and simultaneously the brake pedal sunk into the floor and braking abilitywas lost. This happened about 4 feet from my garage door and this caused my truck into the garage door. I have a driveway video of me on the phone and then the car being accelerated through the garage door.

Even with the recall done the brakes do not stop the vehicle on the second brake application if you are at slow speeds. If you brake at slow speeds release the pedal and brake again you virtually lose all brake power.

Brakes did not work. It felt like I was pushing through concrete. Had to swerve to avoid collision. Had to shift to m to slow vehicle down while pushing with both feet to come to a complete stop.

While in line at a restaurant brakes became hard to push ,chattered and the vehicle was hard to stop. The vacuum pump is the problem there is a recall on this year and make but mine is not covered . Nhtsa campaign number: 19v645 and 20v603.

I was in a line for the car wash and my brake pedal got hard and I had to apply a lot of pressure in order to get the car to stop. I was able to get out of line and got back on the road and the car was breaking fine but as soon as I got in traffic and was at a slower speed the pedal would vibrate and again the pedal got hard and was difficult to stop. I made it back to my work which has a hill pulling in, going down the hill as I pressed the brake pedal it got hard and did the vibrating thing again. I had my 2015 chevy Tahoe towed to a dealer where im currently awaiting a diagnostic.

"service trailer brake system" warning illuminates on dash repeatedly while truck is running. This warning is extremely distracting to the driver, as it does not cease. It indicates an issue with the trailer brake system, which makes it unsafe to tow anything.

Took vehicle to dealership and they did a recall on the brakes. I was driving down the road and lost all breaks almost causing a major accident. Break light came on. Vehicle was in motion and would not stop, I had to slow the truck with emergency brake and downshifting the transmission to avoid a collision with a dump truck.

I decided to take a day trip up to lake Tahoe- from folsom California. It's about 88 miles away. We made it to the top of the summit and on the way down my brakes stopped working. It was as hard as rock. I couldn't push down on the brake pedal at all!! it was so scary. As the people in front of me would brake I had to use my parking brake to slow is down. My only option was to crash into the person in front of me to stop us or use the guard rail and possibly go over the side of a cliff!! my car was loaded with 5 children and 2 adults. We were all terrified. I had no indication as the driver that anything was wrong with my brakes until that moment. There weren't any lights or warnings that something wasn't working properly. My hopes is to report this and not let it happen to anyone else.

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.

Unable to brake. While attempting to slow down my brakes are making my vehicle unable to stop properly. Took my Tahoe to chevy dealership and they were able to fix is. This issue has been going on since then end of last year. So I've been very limited to being able to drive. On April 9th I went to do a curbside grocery pick up with my 1 year old and 3 year old while leaving the grocery store my brakes went out. I was able to pump my pedals turned hard making it u able to brake I forced my leg to push down enough to put it on park and turn my Tahoe off. I waited 10 min to to attempt to leave to the grocery store and it happened again. I called my husband for help he arrived changed out the car seats and attempted to drive him slow. As we were arriving back home the brakes went out again inside the garage at our home. Tahoe is at the dealership getting the brakes fix so I hope everything is back to normal after it being fix.

When applied te brake pedal some time feels hard and the pedal goes to the floor ( that is in low rpm when I'm going to park the vehicle) also when I'm going to parking in reverse feels more noise and won't stop totally even with the brake pedal all the way to the floor. Thank you.

In a drive thru, pressed brake down and the pedal was rock hard. The Tahoe didn't stop for an extra 3', which almost caused me to run into a chik fil a worker! he walked to my window mad, and I told him the brakes aren't working and to move the cones so I could get out of the drive thru. He did. I pumped the brake peddle and they worked enough for me to limp it to a mechanic right near there. He diagnosed a vacuum pump and charged my employer, lbb associates inc in columbia MD $524 to repair.

I 2019 around March to may I took my car to the Chevrolet place in claxton, GA due to my brakes not working properly and showing "brake assist" message. They had my car in their shop five times for this matter. First three times they couldn't find anything, fourth time they replaced the wrong part and cost me almost $500. Fifth time they replaced in under the recall that was out then. Now, Feb 2020 my car has brake issues again. This time my car is showing "stabilitrak" and "brake assist". They are wanting to repair a hub, a module and struts and saying that this is also due to a "side detection system". My struts were related last year before the previous brake repair. I have done my research online and seen that many vehicles from many year makes have had these issues with their vehicle and gm is avoiding the issue. I have two small children that ride in this car and one was in the car with me when my brakes didn't work properly this past issue. My car was now been in the shop for brake issues 6 times and this side detection issue I think needs tone looked into further being so many customers are having issues with this.
