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 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.

I am writing to report a persistent issue with my Chevy Malibu, specifically related to the Stabilitrak system. The Stabilitrak light intermittently flickers on and off while driving, which raises significant safety concerns. This malfunction has been ongoing, and despite efforts to diagnose the problem, my local auto mechanic has been unable to pinpoint the exact cause. Services Performed: Initial diagnostic checks were conducted to identify any fault codes related to the Stabilitrak system. The mechanic found no definitive issues but noted that the warning light's behavior indicated a potential underlying problem. Each visit has led to additional uncertainty, with suggestions from the mechanic to proceed through the GM flow chart for further diagnosis. However, this approach may lead to extensive labor costs with no guaranteed resolution. Financial Burden: The recommendation to follow the GM flow chart for diagnosis is concerning, as it may result in significant and unnecessary expenses without a clear outcome. As a consumer, I believe that a properly functioning diagnostic system should provide clarity on such issues without incurring exorbitant costs. The erratic behavior of the Stabilitrak system poses a serious safety risk while driving. This system is critical for maintaining vehicle stability, particularly in adverse conditions, and its failure could lead to loss of control of the vehicle. I have been made aware of other drivers experiencing similar issues with their Chevy Malibu vehicles. It raises the question of whether there is a known defect in the Stabilitrak system that warrants a recall. I urge the NHTSA to investigate this matter further, as it seems that GM has not taken the necessary steps to address these concerns

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)

The Power Brake Vacuum Assist Failure nearly caused a wreck. The part failed while we were driving on [XXX] going 65 miles per hour on a busy highway. As the breaks gave out the engine light said “Reduced Power”. Moments later, the breaks stopped working and the engine stopped running. We were able to coast off the highway and into an HEB parking lot and have the vehicle towed. The mechanic took the part off and found that it was in pieces causing further examination of the engine to look for the missing metal. Pictures are available to see the damage. Even after completing the repairs the vehicle is showing reduced power. We are still trying to get it fixed but understand that the Chevrolet company is aware of the issue but never issued a recall.

Shift to park warning continues to come on daily when I go to put my car in park. I have to fidget with the shifter to get the computer to recognize that my car is in park and the car will then shut off. Recently I was stopped at a red light, tried to accelerate at the green light and my car completely shut off, while I was still in drive. I could not accelerate and had to place my car in park. Then my stabilitrak sensor came on, along with a notice that my battery saver was on. I had to call a police offer to help me off the road. The car was then able to turn on and I drove it home but this is not safe.

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.

When parking car we place the shifter in park, and psh the button to turn off car it states to “Put shifter in Park” after wiggling the shifter that is clearly in park the car will shut off. Also the breaks will pulsate at slower speeds like the ABS is kicking in, but is not the case. Along with the pulsating there are loud thumping noises. Car today when driving did same thing the said “reducing engine power” almost made it home then completely died on me in middle of road. Was told it could be because of bad vacuum pump, brake booster sensor, and brake booster by my mechanic. He said in newer cars this would prevent the car from starting.

Driving down highway slowed down brake assist kicked in for no reason I was stuck in traffic not moving but maybe 2 mph brakes locked up got super hard codes read brake booster and vacuum pump. Screen went black “parking assist off” came on dashboard earlier that morning but nothing seemed to be wrong with the car. Thank God I wasn’t going faster I could have died!

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.
