At low speeds mainly backing up the abs will kick in on dry blacktop. Sometimes slowing down for a stop sign i can feel the brake pedal pulsing which leads me to believe its the abs kicking it when its not supposed to be. The tahoe has newer brakes and new tires.

Brakes fixed as part of recall. Transmission is recent problem and has since been fixed. Code p0741tcc pump, metal in pan, torque converter coming apart, valve stuff off. Our transmission failed and had to be replaced. When reviewing with staff, no surprises. They were aware that this transmission can be problematic.

1) "Service Brake Assist" sometimes appears on the dashboard when I start my vehicle. When this occurs, the brake pedal is extremely difficult to push, and increasing stopping distance is required because the vaccuum level drops. 2) Since the Electronic Brake Control Module resets within the vehicle's computer when the vehicle is turned off/back on again, the dealership cannot duplicate the problem; as it does not happen all the time. 3) There is an active recall no. 19V645000; Recall date: September 6, 2019; on the make and model year of my vehicle - 2017 Chevy Tahoe - for this exact issue; however, my specific VIN does not have any recalls tied to it. If you can please add my VIN to the same issue happening with recall no. 19V645000, I would appreciate it. 4) I contacted GM, and all they kept telling me is my vehicle does not have a recall tied to my specific VIN; however, my 2017 Chevy Tahoe is exihibiting the exact same symptoms as that which is listed in recall no. 19V645000. The solution is for the dealership to reset the Electronic Brake Control Module; however, they will not do so because they cannot replicate the issue and my VIN is not coming up on the recall list for my vehicle. 5) In the recall notice, it states that GM "has not yet provided a notification schedule", so if you can possibly let me know if my vehicle will be recalled for this issue, I would appreciate it since not having acceptable brakes to the vaccuum level drop is a safety issue. Thanks for your time! Please feel free to contact me with any questions.

Transmission wouldn't go into reverse, neutral brakes wear down extremely fast.

My brakes become very very hard to push when it senses anything near my car. I noticed this was a recall issues so I took it to the dealership (gerry lane Chevy in baton rouge, Louisiana) and they tried fixing it but were unsuccessful. The second attempted 'worked' or at least they said it did. I'm still having issues with it and have since the moment I left the dealership. They refuse to look at it without me paying this time.

The contact owns a 2017 Chevrolet Tahoe. The contact stated that after driving for 4 hours at 55 mph, the brake pedal was depressed to the floorboard with an abnormal grinding sound. The service brake assist warning message was displayed on the instrument panel. The contact engaged the parking brake to stop the vehicle while driving up an incline. The next day, the brakes resumed normal operation on the drive home. The contact stated that since the failure, he had experienced intermittent brake failure while traveling at various speeds, with the same warning light flashing on the instrument panel. The vehicle was taken to titus-will Chevrolet Buick GMC Cadillac (2425 carriage loop sw, olympia, wa 98502) and it was confirmed that the failure was caused by a defective vacuum pump. The vacuum pump was replaced however, the failure persisted. The vehicle was taken back to the same dealer where it remained in their possession unrepaired. The manufacturer had yet to be notified of the failure. The failure mileage was approximately 75,300.

I have an open recall (N192268490) on my SUV that knowingly does have issues when I am driving and the breaks will not stop my vehicle properly. After several attempts to the local certified Chevrolet dealership and service departments and I opened a case number with Chevrolet customer service, the issue has not been remedied and still remains a driving issue and safety concern. Since December 2019, I have taken my vehicle to the 2 local certified Chevrolet dealerships and service departments on 3 different occasions. Both locations told me the software is not updated properly therefore my vehicle will not except recall. After my first attempt to get the recall fixed and the service department was unsuccessful, I contacted Chevrolet directly and a case number was issued (service request number: 9-5847462774). I communicated frequently with Chevrolet on resolving the recall issue with my vehicle. The end result, I was told by Chevrolet customer service that the issue is unable to be repaired and the recall could not be completed due to a software update that Chevrolet needed and they were uncertain if/when the software update would be available. Since the case with Chevrolet has been opened, I have taken my SUV to another certified Chevrolet dealership and service department on 2 other occasions and the recall has not been resolved. After the 3rd time I have taken my SUV in for this recall, I have attempted to contact Chevrolet customer service again via email and I have gotten no reply back or return phone call. Is this how a person, with a family, that has a safety issue and a recall on a vehicle should be treated? especially, when the vacuum line for the brakes in my Chevrolet Tahoe knowingly do not seal and the brakes do not operate as intended.

In September of 2019, GMC issued a recall for several GMC vehicles regarding "service brakes, hydraulic:power assist:vacuum". as such, the vehicle was serviced at the dealership per the instructions issued by GMC. However, several months later, while operating the vehicle in reverse out of a crowed parking lot, the brakes failed to stop the vehicle. Placing the gear in neutral along plus the emergency brake, was required to stop the vehicle. The was an extremely close call to the safety of the surrounding bystanders in the parking lot. Upon discussions with both the dealership and GMC, it was reported that the current recall only reprograms the components (reference the letter issued by GMC and the NHTSA's web site for this recall). It was further commented by both the service manager at the dealership and customer service at GMC, that this will not address all vehicles identified in this recall, meaning more action may be required to fix the underlining issue. In this case, several components were needed to be physical replaced, namely the vacuum pump. In addition, it was acknowledged by both the dealership and GMC that a certain percentage of these vehicles identified in the original recall will experience similar issues (brakes failing to stop the vehicle). During the call to GMC customer assistance (866.790.5600), the senior manager refused to take the advice to inform all customers/consumers of this dangerous ongoing risk. Even though it's a known failure, GMC has yet to provide additional notification to consumers that the current recall may fail to address the underlining safety failure to the braking system. GMC should issue a new recall to advice the replacement of the physical components of the vacuum brake assistance system by all effected vehicles immediately. Otherwise, they will not replace the parts unless the consumer experiences an actual failure.

Depressing the brakes, failed to bring the vehicle to a stop. While at a low rate of speed, the brake pedal would sink to the floor, and there would be no stopping power. This occurred 3 times in a single day. We rolled through the end of several driveways, directly into the middle of the street. We contacted the dealership, and they confirmed there is a service bulletin for the issue, and the vehicle should get immediate and necessary repairs. If it helps, the service number within Chevrolet is: #pit5361D attached is an image of the exact diagnosis and confirmation from the Chevrolet dealership. We were fortunate no other traffic was approaching us. Others may not be so lucky!

Driving in traffic slow speed, brakes went to floor, lost power brakes, possibly vacuum pressure. Very hard to stop vehicle. Brakes worked after driving at a higher speed while attempting to exit the road. This is a brake booster/vacuum loss issue in my opinion. This is a 1 year old vehicle. This should not be happening. I have video of this happening.

Hard brake pedal resulting in little or no stopping power when applying the brakes at low speed. To get the vehicle to stop, you must stomp on the pedal as hard as you can. The situation typically occurs when parking. The brake application or two are fine, but after that the brakes fail. This same issue appears to be well documented under NHTSA id number 10081053 and GM pit5361B, however those do not include the 2017 model year, and I am seeing what appears to be the exact same issue on my 2017 Tahoe.
