2017 Chevrolet Malibu Brakes Problems

Vacuum pump came apart inside the engine causing metal pieces to enter the engine

Breaks are locked up, car won't start due to faulty Vaccum pump and brake booster!

Yes, my brakes have failed twice with my children in my car both coming to a stop sign almost causing us injury or death. I have contacted Chevrolet several times about this issue. It has happened again costing me close to $4000 in repairs.

the brakes failed the vacuum pump went work while driving the car

The contact owns a 2017 Chevrolet Malibu. The contact stated while driving approximately 65 MPH, the instrument panel displayed the message “Reduce Engine Power” with the check engine warning light illuminated. The vehicle immediately decelerated independently. The contact continued to depress the accelerator pedal; however, the vehicle failed to exceed 35 - 40 MPH before decelerating again. The contact pulled over to the side of the roadway and waited for approximately 15 minutes before continuing to drive; however, the failure persisted. The vehicle was taken to a certified mechanic where it was diagnosed and determined that the ABS, Power Train, and Throttle Sensor all had failed and needed to be replaced. The vehicle was not repaired by the mechanic. The vehicle was taken to the dealer but was not yet diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 70,000.

On Thursday, [XXX] my [XXX] son was driving my chevy malibu coming down the hill to get home when the brakes went out. He could not stop the vehicle and had to pass our neighborhood and let the vehicle slow itself down. He was able to get stopped and turned around and made it home. Saturday, [XXX] we decided maybe it needed new brakes and took it for new brakes. New brakes and rotors all the way around did NOT fix the problem. The brake was like hitting a brick and would not stop the vehicle. I had the vehicle towed to a repair shop and they found that the vacuum system for the brakes went out. He also noticed that cam shaft was cracked. Upon research through the internet I found that this problem is common and a class action suit has been filed against GM for the same problem. I am unsure why this is not a recall as its a safety issue and my son could have been injured or injured someone else. This has been an EXTREMELY expensive repair for us! When they went to replace the cam shaft there were several parts of the cam shaft just blown all over the engine. We still have not found all of the missing parts. This has caused most of the seals to have to be replaced as well. I do not have a repair receipt yet as the vehicle is still in the shop INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vacuum pump failure caused engine damage.

The brake booster and vacuum pump keep failing. I’ve replaced the booster 3 times and the pump 2 times the first time the pump went it broke off and broken pieces of metal had to be taken out of the engine. I’m making payments on a vehicle that is in the shop repairing the same issue every 3 to four months.

1, break vacuum pump. I have the defective unit available 2. My safety, my passengers and all other drivers were put at high risk 3. Defective vacuum pump verified my independent mechanic 4. Inspected by mechanic. Have not had anyone else inspect. 5. No warning of complete break failure

Engine reduced while on the highway.

Brake failure, turning into my parents driveway I had to swerve to miss a truck and drove in the yard because of it. It has been diagnosed a faulty brake vacuum pump that caused this failure. I am getting it looked at by a mechanic of Friday and hope that this issue didn't cause further problems with the engine/camshaft. From doing research it seems that many other people have experienced the same issue with the same year vehicle (2017 Chevrolet Malibu). I have also in the past had to get my car fixed by a GM mechanic for the issue of the car giving the "reduced power mode" and basically shutting off while driving down the street. That has now been fixed but was also an issue GM was aware of but I never received a letter or anything about the issue or that there was a recall on it.

The contact owns a 2017 Chevrolet Malibu. The contact stated while driving approximately 65 MPH and attempting to depress the brake pedal, the vehicle failed to stop as needed. The contact was able to get to the side of the road but ended up in a ditch which stopped the vehicle. The vehicle was taken to the dealer who diagnosed the vehicle and determined that the brakes had failed and that the vacuum pump needed to be replaced. The vehicle was repaired; however, due to the manufacturing of the braking system, the damages was extensive, and the vehicle was undrivable. The contact stated that additional parts were needed to fix the vehicle. The manufacturer was made aware of the failure. The approximate failure mileage was 121,000.

1) brake system failed , yes it’s available for inspection 2) the brakes became very hard not being able to push down to use brakes , had to go to the right into ditch to avoid many vehicles that were ahead of me , this was very scary for my family and I , I’ve had nightmares since . 3) brake booster has been confirmed by the dealership as the problem 4)inspected at the hm dealership 5) There was no warning lights before incident happen

While driving on 12/28/2022, my brakes suddenly became very difficult to apply pressure- almost causing a cramp in my calf because I had to press down so hard. Took the car to a repair shop, only for them to tell me my brake pads are fine. It turns out the problem is with the vacuum pump associated with that part of the car. Looked online to see if this was a common problem and as it turns out, there's a class action lawsuit in litigation about this very issue.

The contact owns a 2017 Chevrolet Malibu. The contact stated that while pulling into a gas station the vehicle lost motive power without warning. The contact stated that she was informed to top off the fuel and the vehicle was able to restart and drive with no further issues. The contact stated that the vehicle was able to restart several hours later. The vehicle was not taken to a dealer or independent mechanic for diagnostic test or repair. The contact stated that recently while driving approximately 20 MPH, the brakes locked up as the brake pedal was depressed and an abnormal noise was heard. The contact stated that the vehicle stopped as the brake pedal traveled to the floor. The vehicle was inspected by an independent mechanic that diagnosed the failure as a defective brake vacuum pump that needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure however, no assistance was offered. The failure mileage was unknown.

My vehicle has become harder to bake almost to the point that the brake doesn’t work took my car to have it accessed and was told my brake booster is damaged and causing my car to barely brake it is extremely dangerous can cause harm to myself or my family

Vacuum pump has stopped working properly causing it very difficult to brake. Autostop feature has stopped working properly due to this problem. This is the second time I have had issues with the vacuum pump.

As I was driving in a 45 MPH two-lane road, the car in front of me wanted to turn left and when I stepped on the brake pedal, it was stiff. The car wouldn't slow down. So, I quickly stepped on the parking brake which helped and possibly saved my life and the life/lives of those I could have hit. One can only imagine the fear I had. The check engine light came on right after. When tested it reported P0556 - Brake Pressure Sensor; something that has to do with the Brake Booster Vacuum Pump. When I talked to a mechanic, he recommended I report this issue here because this should not happen.

This vehicle has been in the shop multiple times for the vacuum pump brakes to be replaced by the dealership. This is the 3rd time that the time the car will be taken to the dealership for the car to have the vacuum pump replaced, due to almost being in a major accident the 2nd time in the middle of a 4 way intersection because the brakes went out and the vehicle had to be towed. The brakes continues to lock up and is a danger to our safety. This car has been reported to General Motors to made as a recall. This car is consider a LEMON at this point and I would like for someone to contact me at [XXX]. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
