Vehicle loses braking capability at low speeds, sometimes voltage issues cause stability control error, and even complete loss of engine power and vehicle control (engine shutoff). This has been recurring approximately once per day for two weeks, generally at very low speeds and turning into a parking spot. Typically, ABS engage and power brake assist is lost, which requires more more effort to stop the vehicle. Can also happen in reverse.

My condenser went out at 96K. I contacted GM and they stated that they had a recall on the condenser. Took the vehicle in to a GM/Chevrolet dealership and they began to inform me that the recall only is for vehicles less than 60K. They stated that GM knows there is a problem but due to mileage my vehicle is not covered. Due to living in the South I can not afford to have a car and not have air. So we fixed the condenser out of pocket. 1st-the condenser part was on a national back order and they stated that it could take up to a month to receive the part. Alert that there is a problem with the manufactory making condensers for GM cars. 2nd-the part was $200-300, although the service was $1100. 3rd-6 months after the replacement of the condenser and all working fine, paying out of pocket. The transmission goes out and the connection is associated with the replacement of the condenser. GM is aware of this issue but only wants to assist with people who mileage is less than 60K. There is obviously a serious problem and GM has not taken ownership! total cost in 2yrs for repairing and fixing 1part that lead to 3parts $4.5K.

Chevy is aware of this issue. The brake vacuum pump needs to be moved onto a broader recall and not just under a "special coverage" this past weekend at gas pump our break pedal and the ability of the car to stop almost caused a major tragic accident. Fortunately last minute the truck stopped after I put both feet on the pedal and pushed as hard as I could. This issue left unresolved will get someone killed. These vacuum pumps need to replaced and Chevy needs to stand behind the issue.the people that don't have 600 bucks to replace these pumps are driving around with a loaded weapon on the streets if they are outside the parameters of their bulletin. I know Chevy will do the right thing and recall and fix this brake problem. This was at slow speeds in a gas station backing to get closer to the gas pump. There was no accident, no report filed, or police called but this could have ended poorly.

The brakes seem to loose power. It appears that the vehicle is loosing vacuum and the operator looses power brakes. I almost rear ended a car during a traffic backup on the interstate because of the loose of power braking efficiency. The vacuum pump is not making the appropriate amount of vacuum to have power brakes.

When backing up or driving forward slowly the brake peddle gets really hard and vehicle is very difficult to stop. Almost was not able to stop. I was in a parking lot, used my emergency brake to stop as well as putting the car into neutral.

- Prescott Valley, AZ, USA

Was coming up to a stoplight with major traffic and had stiff to no brakes. Was within inches of hitting the person in front of me. My 'service brake assist' light came on. I was told by a Chevy service department that my brake vacuum pump had failed and that this was common in the 2015 Suburban.

- Fay, OK, USA

I was driving my 2015 Chevrolet Suburban with 7 family members at about 45 mph as we were coming into a city. Two of us started to hear a slight squeal like when a belt slips. After that I shut off the A/C to see if it was that. It was not. About that time traffic started to slow down in front of me. When I stepped on the brake to slow down it was hard and at the bottom of the pedal stroke. I lifted the pedal with my foot and it just fell back down. I was able to get the Suburban to stopped in time before hitting the car in front of me. I had to drive the vehicle cautiously for another mile or so to find a safe spot to pull off. I had the vehicle towed 90 miles to a dealer close to a relative as we live another 250 miles away. When I talked to the dealer, he said there was a service bulletin for this issue but I believe he aid it was only covered up to 69,000 miles. Our Suburban has 108,000 miles on it as we live in a very rural location. It is 45 miles on way to the grocery store. I have owned GM products all my life and have never been as disappointed in their handling of their customers as I am now. This issue with the brake vacuum pump has been a known issue and they are not covering the repair of it.

- Ione, OR, USA

Vehicle was in motion, at slow speeds (under 25mph) and when the brake is pushed, the brake pedal became hard but failed to stop the vehicles forward motion. This happens intermittently and is a huge safety issue. This occurs only at slow speeds and prevent the driver from stopping the vehicle even if the brake pedal is pumped. This occurred again today and Chevy was contacted and stated they have no recalls or issues with their brake system even though there have been numerous complaints logged to NHTSA. When this occurs there is no braking for the vehicle and will cause an accident if not fixed.

- Layton, UT, USA

Break assistance stopped working as I pulled into a parking spot at work. I needed to put extreme pressure on the break pedal in order to stop the truck at very low speed. Vacuum pump was replaced in truck

- Lino Lakes, MN, USA

Brakes lock up and can't stop the vehicle on numerous occasions. Can't push the brakes in and poses a huge risk to accidents. Needs recalled

- Satellite Beach, FL, USA

On at least 5 occasions the brakes have failed to provide the necessary stopping power. When inching forward after a complete stop, I would apply pressure to the brake pedal and the pedal would immediately lose pressure and sink to the floor. I would have to apply additional pressure to the pedal in order to stop from hitting the vehicle in front of me. It would also feel like the ABS system would kick in and would pulsate. If I immediately depress the brake pedal and press it again in quick succession the pedal regains pressure but does not regain normal brake functionality.

- Bristol, RI, USA

On quite a few occasions over the years, while driving at low speeds and depressing the brake pedal, the car has been very difficult to stop. This presents a scary situation because I am a 200 lb man and I can barely stop this large vehicle. My fiance is very petite and she is terrified to drive it. I know this is a very common problem with the 2015 Chevy trucks and SUV's because I personally know others with this exact same problem. It seems as though Chevy is just biding time awaiting for the auto warranties to expire rather than fix this deadly problem.
