My 2015 Chevrolet Tahoe's interior lights flash brightly when the brake or left turn signal is applied. It is a very bright flash and extremely distracting at night. It happens while driving. I can imagine it is also very distracting to other drivers at night as well. It happens every time the brake or left turn signal is turned on. Online research indicates other people also have this issue. It happens on all roadways at all times. But specifically at night is the safety concern. My passengers in the rear have also been complaining that it is physically stressful to them when the interior lights flash without them expecting them too.

I was driving in traffic going about 5mph and when I applied my brakes they were not working 100% I had to push the pedal to the floor and the truck kept rolling. I had to had to figure out a way to safely move to the shoulder of the freeway to avoid accidents. I waited on the shoulder of the freeway for about a hour for traffic to stop. I was finally able to get off the freeway so I could check the brake fluid it was full. I knew there wasn't a problem with the brakes because they had just been replaced the prior month. I knew the vehilce was not safe to drive home so I left the truck at davis Chevrolet at their night drop. I talked to a service technician and he informed me that he has seen this issue a lot with 2015 Tahoe's, and infact 3 2015 Tahoe's were brought in the same day November 3,2017. Before looking at my vehicle the technician told me it was the vacume pump but he would call me back to let me know for certain. Once they looked at my truck he said it was the vacuum pump that needed to be replaced and it was not under warranty. I don't understand how GM knows about this issue and still does not recall it, this can cause major accidents and potentially cause a life. It's obvious there is a issue with tje vacuume pumps in tje 2015 Tahoe's and GM needs to take responsibility and do a recall before someone dies because their brakes fail due to a vacuum pump not working.

The dealership notified me that there was a faulty brake vacuum pump, and brake booster, and that it failed because of moisture penetration. Further, General Motors has issued technical bulletin pit 5361A/B/C to address this known issue. My Tahoe has 59,000 miles on it. After further research, this is a known issue by GM at the time of my vehicle purchase in December 2014 and further, has been acknowledged through technical bulletins to the GM dealers.

The General Motors company has been negligent in its handling of this important safety (not cosmetic) issue.

As I was sitting in the vehicle in park, I placed my foot on the brake and noticed that the brake assist had activated while in park. I was unable to push the petal down. I was able to move the shifter into drive with my foot on the brake, but the vehicle immediately plunged forward. As I continued to try and depress the brake petal, the vehicle finally slowed to a stop. Before I could get off the road and out of traffic, the brake assist continued to be locked up and there was no brakes if I shifted into reverse. I was extremely concerned for mine and my children's safety as this could have caused a very serious accident. The brakes did not stop the vehicle and were defective due to the vacuum pump "going out". the vehicle is only 2 years old and has 49K miles.

When applying the brakes my car doesn't stop 100% of the time. 1 time during highway slow moving traffic, 3 times backing out of my driveway (flat surface), 4 times when on incline/decline of road. When applying brakes, horrible chattering vibration comes from left front tire area, chatter vibration is felt in brake pedal. No matter how hard I apply the brake the car keeps going - it will finally stop, but I almost hit the car in front of me at the one highway occurrence, 2 times car finally stopped just before going over edge of property when pulling forward & backward to turn around in tight area. In each instance I am moving at a very slow speed. I contacted dealership, they told me I wasn't the only one calling about this happening but since I'm over 36,000 warranty they will charge me to ck it out, probably can't recreate the problem, said it was probably ABS but nothing they can do about that, suggested I find a dealership close to me whenever it happens again!
