Intermittent reduction in braking power while performing parking maneuvers (parallel parking). Feels like loss of power brakes requiring very heavy force to stop vehicle - very unnerving. Vehicle was taken to dealership for inspection and dealer replaced brake pads and rotors on front & back. Dealer claims issue is unrelated to recall 19V645 & 20V603 but I suspect it is as symptoms are identical.

I am writing in concern to a brake pump malfunction and air bag sensor failure. The vehicle is available for inspection and has been inspected/confirmed by dealerships. The brake pump is bad and falls under the recall by GM but because it was over the mileage threshold, it didn-€™t qualify. The brakes don-€™t work well at all. The air bag sensor in the passenger seat went bad and now shut off all my airbags and GM won-€™t add my vehicle to the recalls they have already issued on other vehicles for the same issues. My safety is at risk with my lack of air bags for us. Others-€™ safety is risk due to the bad brake pump that I cannot guarantee will continue working, especially upon an immediate need to brake in any emergency situation. I have contact the manufacturer 2 separate times and they refuse to include my vehicle in their safety recalls. This is a serious matter. Someone could get hurt or worse. I had no warnings or indications that these were issues until they became one. I had to get quotes of $1200 to get these two issues resolved and don-€™t understand how this is a known problem but they refuse to help me in any way. I-€™m not asking for a replacement truck or engine. Just functioning safety features!!! The truck is only 5 years old.

1) Brake system, yes. 2) The vehicle did not stop when the brake pedal was depressed (known issue with GM). 3) Yes, GM provided an independent investigator and confirmed the brake system failure. 4) Yes. 5) No. On May 29, 2021, at approximately 9:35 AM, I was traveling Northbound on Interstate 5 and exiting the freeway on Highway 46. As I exited the freeway, there was slow moving traffic, I began to brake and experienced no braking at all and the ABS kicked in. At that time, I was traveling at approximately 10 miles an hour when the impact accorded with the vehicle in front of me.

Believe the vacuum pump is faulty. Hard braking g or no brakes when going slow or go in reverse.

I had a recall on 2 different trucks (15 & 16 Silverado 1500) and the dealership claimed they fixed the problem but the problem still exists. I sold the 15 but currently still have the 16. I have reached out to the dealership and they told me it's been too long since I had the recall addresses (Nov 2020) so I will have to pay for the $180 diagnosis fee. My truck is doing the exact same thing it was doing before. Even after the dealership "fixed"the problem, I could all notice the issue. I love GM but I'm very disappointed in the efforts they have put forward to resolve this dangerous problem. I'll not sure if my next vehicle will be a GM product

- Austin, TX, USA

I was pulling a trailer and was trying to back it up to park it and I lost my ability to brake. It was scary asks dangerous. I have taken it to the dealership and all they did is reprogram it and not address the actual vacuum pump that has the sludge build up on the screen. Needless to say, even after the recall, I am still experiencing brake loss at low speed. I'm hey disappointed in GM. This has happened to my '15 and '16 Silverado's. I'm not sure if I'll buy another GM vehicle again if my safety is compromised and they will only bandaid the problem

Pedal went to floor and would not stop when parking and also in bumper to bumper traffic

- Lafayette, LA, USA

The contact owned a 2016 Chevrolet Silverado. The contact stated was driving 25 mph when the brake brake pedal was depressed however, the vehicle failed to stop. The contact stated that he had to depress the brake pedal with both feet as it travelled to the floorboard. The vehicle did not stop and decelerated in speed which caused the contact to rear-end a vehicle, which also caused that vehicle to rear-end a vehicle as well. No injuries were sustained and no medical treatment acquired. There was no police report filed. There was no warning light illuminated on the vehicle. The contact stated that the ABS failed to engage. The contact had the vehicle towed to their residence. The contact insurance company had the vehicle towed to a tow yard, where they inspected the vehicle damages and deemed the vehicle a total loss. The local dealer and the manufacturer was not made aware of the failure. The contact mentioned that he believed the failure was related to NHTSA campaign number: 18V578000 (service brakes, hydraulic) and 16V069000 (service brakes, hydraulic). The failure mileage was 78,000.

At low speeds my brakes stop working. The brake pedal becomes very stiff and I have to use both feet pushing down as hard as I can for the vehicle to stop. Also, the head light switch inside the vehicle does not work. When I turned the dial off of the auto lights I saw smoke coming out from behind the dial.

When driving at low speeds the vehicle sometimes continues to roll even though the brakes are fully pushed. This seems to happen intermittently and is noticeable when pulling into the garage. The brake pads were recently evaluated during a routine service at a GM dealership.

A lot of force needed to break at lower speed

- Yulee, FL, USA

Increased brake pedal effort caused by faulty brake vacuum pump. Stiff brake pedal at low speeds and increased stopping distance

- Nevada, IA, USA

Lose of breaking power at low speed. I lost all breaking power trying to maneuver in a parking garage and parking lot. There are no lights that come on during or after this. I have had it happen 3 times almost resulting in damage to my vehicle and others. The break peddle stiffens and provides almost no breaking.

At slower speed the braking system seems to fail. The brake pedal needs to be pressed hard but sinks and the car does not stop. This is only happens at speeds less than 15 miles per hour. It feels like the cars does not stop and I have to put much more pressure than usual. I usually put car in park and restart it and it is fine until the next time. It has happened numerous times in last couple of years. I did take into the dealership and they could not find anything wrong

Vehicle brakes become very hard to depress making it hard to stop the vehicle I find this happens more at slower speeds and in reverse

- Greensburg, PA, USA

The brake pedal on my truck turns real hard and the brakes don't seam to engage as usual this happens at low speeds or in a downhill. This has happened in the highway on I15 coming to Nevada from California on a downhill with traffic present and at low speeds. It has also happened in a drive thru and a parking lot truck was in motion and at low speeds I applied the brakes and the pedal turned hard/stiff and makes a screeching sound. The truck does come to a stop but travels more than usual when brake pedal is normal.

- Las Vegas, NV, USA

Pulled into the parking lot at work at low speed when applying the brake to backup I noticed the brake pedal was very hard. I put my truck in reverse to back into a parking spot, the brake was very hard and wouldn't stop. When hit the fence the truck finally stopped. Called the dearler where I got the truck, they said there's a recall and the brake system needed to be reprogrammed but that wasn't going to fix it. 2019 I took the truck in @ 60,000 miles, they did a reprogram and said they couldn't do any thing else unless there was another brake recall. The bad thing about this whole brake problem is GM knows what the problem is and won't fix it. GM has and will fix the problem if you pay 12 to 1,600 dollars. Since they did the reprogram I have 80, 000 miles on the truck and at low speed at a traffic light or in parking lots the brake is very hard and the ABS system will activate. Same problem different day. I need new bombers now. I guess GM is waiting for someone to get hurt.

While driving at parking speed or drive through speed my brake pedal gets hard and I lose brake. I've almost wrecked a few times already because of this issue.

- Tulare, CA, USA

I got a recall done buy a Chevy dealership in storm lake Iowa, so they say they did it but after a few months of driving I noticed the my truck started breaking different at low speeds just like the recall was for the recall number is N192268490. Just didn't know if there was something I could do so I don't have to pay to get it fixed when it's not my fault the breaks won't work like they are supposed too!
