On 12/15/2018 my brake vacuum pump went out. I had it replaced at a dealership. Total cost $1506.56. Master cylinder, brake booster, and a connecting pipe had to be replaced also. April 2019, I receive a letter from GM, describing this issue and saying if I have less than 72,000 miles or bought it new within the last 6 years, whichever come first, they will fix it. Brakes are a very serious component. This problem dates back to the 2014, S. I feel GM should reimburse me for my repair cost, since the problem came from their plant. I have more miles on my truck than they say they will cover. Brakes and the components are things they should cover. I have invoices and proof that I paid these expenses. Every person pays hard earned money for a new vehicle. Manufacturers should be required to back their vehicles. I was driving on a side street when this pump went out. I had all I could do to stop it, using both feet on the brake pedal. Thank you for your time.

When backing down a steep incline, there is a complete loss of power brakes. I can barely stop the vehicle when backing down my driveway. This will be a safety issue when I back a boat into water. The dealer advised replacing the vacuum pump and hose with new design.

When at a slow rolling speed brakes are extremely hard to brake, mainly when in parking lots or backing my boat in the boat ramp its extremely scary and seems like the truck wont stop rolling. This is so unsafe and scary. Its almost like the brakes dont work. But im pretty sure its the vacuum pump brake system.

When I go slow the break pedal get so hard I can stop

When braking frequently in a parking lot or at low speeds the stopping power gets worse and almost will not stop the vehicle. I have 86,760 miles on my truck currently but this has done it since 20,000 miles and since then off and on.

Increased brake pedal effort, hard brake pedal, and/or potentially increased stopping distance due to low mechanical vacuum pump output. Condition is more prevalent at low speed when softly applying the brake. Decrease vacuum/power brake assist over time, failure to follow recommended oil change intervals could contribute to conditions. Driver's information center (dic) "service brake assist" alert will activate 2-5 minutes after dropping in vacuum level, and diagnostic trouble code (dtc) will also be set. Hydraulic brake system remains functional but may require additional pedal force.

When traveling in low speeds, usually in reverse, I have to increase my break pedal effort and press really hard to stop the truck. This does not happen every time I drive it but it does happen often.

Brake vacuum pump failed which resulted in diminished braking performance. This was very dangerous as we were pulling a camper when it happened. Dealership replaced vacuum pump when vehicle was at 78260miles although condition started before that. We received a letter about reimbursement but it only applies to 72000 miles or 6 years. The repair cost us over $500.

My vacuum pump on my 2015 high country Silverado is going bad, is what the Chevy dealer diagnosed after I explained how when I reverse specially it feels like my brakes are failing and then the peddle gets super hard. They said its not normal but how do you feel safe in my Chevrolet truck if my brakes can suddenly go out?

- Clute, TX, USA

Brake failure, while pulling into or out of a parking spot, brakes lose pressure and become very stiff and stop working. The pedal becomes quite hard and will not work causing vehicle to continue moving forward or reverse. Especially at slow speeds, I have barely missed impacting the cars across the parking lot.

In December 2018 while in a parking lot at low speed, brakes were applied. Brake pedal went about halfway then became "hard." There was no braking power and brakes would not work. This was associated with a "clicking" noise. When car rolled to a stop I started moving again and reapplied the brakes. Same result both in forward and reverse. This happened again in a parking lot on April 11, 2017. My vehicle currently has 83,000 miles. Took it to a Chevrolet dealer and they stated the issue was the vacuum pump and recommended repairs according to their pit5361D. However they stated that GM recently published that they would only warranty the fix up to 72,000 miles. I have not had the repair completed yet.

Brake assist keeps popping up on info screen. There's a delay in braking while parking and when climbing steep grades in 4 wheel drive.

I have been complaining of a braking issue since I purchased my truck in 2015 and have had them inspected at several Chevy dealerships, stonebriar Chevrolet N frisco, huffines Chevrolet in lewisville. We have moved and I took into today and now that the truck is out of warranty I'm being told I have a faulty vacuum pump that could cause my brakes to fail. The dealer, peters Chevrolet in longview, also states unforuntely he cannot see my service records to confirm the previous brake checks which is ridiculous. This is a known issue and GM is taking no accountability in this and demanding a change of $600 to replace. Please help.

The brakes occasionally will get hard when depressing at a low speed and fail to work. This usually happens coming to a final stop in my driveway that is down a slope after I have already been using the brake to slow down some. The vehicle is barely moving when it happens. It has happened a couple of other times going down a slope in our subdivision entrance applying occasional brake pressure at about 20 mph. I had it diagnosed by the local Chevy dealer and they said the vacuum pump and seal needs to be replaced and the brake system flushed. Total estimate for the work was $970 which I did not have done. I noticed online that others have had this same issue.
