Service Brakes Problems of Chevrolet Malibu - part 1

Randomly when I press the brakes the brake lights don't turn on. Other times they work fine. All of the light bulbs are good. All three brake light don't turn on randomly. I have almost been rear-ended on numerous occasions. No dash lights came on. And I have not had it inspected yet just my girlfriend pushing the brake pedal to test the lights. One day they work another they don't then another day they work again.

There have been numerous days that I press brake to start car in which it does not start. I wait until it will. The trunk seems unaligned as there's more gap on right side. Carpet in front floor is not correct as I have to tuck under trim by door constantly. Backup camera seems distorted and has been not correct in lines to park but remains distorted by the unclear view and awkward angle. While driving at times it feels like going into another gear and it's an automatic. The breaking at times is very hard and pushing passengers forward.

While driving my 2013 Chevrolet Malibu (2. 5l), I experienced a sudden and severe failure of the braking system. [insert exactly what happened here—for example: 'the brake pedal suddenly went completely to the floor,' 'the brakes unexpectedly locked up,' 'the vehicle experienced a sudden loss of braking power,' or 'the brake warning lights illuminated right as the brakes failed']. This occurred while traveling at approximately 25 mph on a one-lane road. This total/partial loss of braking power created an immediate safety hazard and a high risk of a crash. The vehicle had to be shifted into manual, then safely coasted to a stop. No prior warning signs or brake issues occurred immediately leading up to this event.

The brake pedal on my vehicle intermittently becomes stuck in the fully raised position and will not depress when I attempt to apply the brakes. When this occurs, I am unable to slow down or stop the vehicle, creating an immediate and serious safety hazard. The problem happens without warning and has occurred multiple times while driving at various speeds. When the defect occurs, the pedal feels locked or jammed, and I have to use extreme force or pump the pedal repeatedly before it finally releases. This delay in brake response puts me, my passengers, and other drivers at risk of a crash. The issue is unpredictable and does not appear to be related to weather, temperature, or driving conditions. I have not made any modifications to the braking system. The defect has occurred both during normal city driving and while approaching intersections. Because the failure prevents the brakes from engaging at all, I believe this is a critical safety issue that requires investigation.

I am writing to report a serious and dangerous issue that occurred with my 2020 Chevrolet Malibu lt on April 27th 2026. While driving on the interstate after work, my vehicle suddenly experienced a failure that made it extremely unsafe to operate. The brake pedal became extremely hard to press, and the vehicle did not want to slow down or stop properly. This created a very dangerous situation while I was driving at highway speeds. Additionally, I noticed that nearly all of the engine oil was gone, which is extremely concerning and may be related to the failure. Based on these symptoms, it appears the vacuum pump may have failed while the vehicle was in motion. This issue placed me at significant risk of an accident and could have resulted in serious injury. I am requesting an immediate investigation into this matter and assistance with repairs. I would also like to know if there are any recalls, known defects, or extended warranties related to this issue. Please advise on the next steps as soon as possible, as the vehicle is currently unsafe to drive.

To whom it may concern, ?I am writing to formally report a critical safety defect regarding my 2020 Chevrolet Malibu. This defect resulted in a life-threatening incident while I was driving on the highway, during which my vehicle failed to stop as required. ?while operating at highway speeds, the brake pedal became extremely hard to depress, making it nearly impossible to decelerate or bring the vehicle to a complete stop. This sudden loss of power assist forced me to manage an incredibly dangerous situation in high-speed traffic. Based on the symptoms, I am concerned that the brake booster vacuum pump has suffered an internal failure, a documented issue for this model year where oil sludge or debris causes the pump to seize. ?in addition to the physical resistance of the pedal, I am concerned about the reliability of the electronic brake control module (ebcm). The failure experienced on the highway demonstrates that this vehicle is unsafe for public roads, as the force required to engage the brakes in an emergency is far beyond safe operating standards. ?I request that the NHTSA investigate this brake failure and determine if a mandatory recall is necessary to prevent similar incidents from resulting in catastrophic collisions. ?please contact me if you require further information thank you [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Car started shaking in the middle of driving it about 30 mph and all the electrical like door locks were going up and down car wasn’t accelerating and an alert came up for stabilizing wheels I believe. It happened for about a couple seconds and then everything went back to normal and randomly happens while I’m driving. Check engine appeared and went to the mechanic shop I usually go to and found out I had ebcm and ecm modules bad. Do some research on the car and noticed it had a recall back in 2014 for ebcm. The problem has resurfaced.

The vacuum pump continues to go out causes code p1101. I have replaced it 4 times and people just in my town are fighting this code for dear life like me! it causes our brakes to barely work and make it completely unsafe to drive as the check engine light goes in and out for maf sensor. It’s not safe. It needs to be recalled. It doesn’t matter if I buy the most cheapest part or expensive part. It has happened on multiple occasions where I replace it and within 2 months, its back on and does reduced power in the middle of me driving on busy roads. I’ve been almost hit and almost caused multiple accidents because I have to pull over.

May 7, 2026 national highway traffic safety administration 1200 new jersey avenue se washington, DC 20590 safety defect complaint – brake system / vehicle control concerns 2020 Chevrolet Malibu dear NHTSA, I am submitting a safety complaint regarding persistent braking and vehicle control issues involving my 2020 Chevrolet Malibu. Prior to December 31, 2025, the vehicle exhibited jerking during braking, all dashboard gauges go to the left, warning lights, reduced power (20-25mph), and inconsistent braking behavior. This situation happens without warning, at any given time, even in the flow of traffic. An independent inspection indicated the brake system was in proper condition, suggesting a more complex underlying safety issue. The vehicle was taken to reed-lallier Chevrolet for diagnosis and remained there for approximately five months. During that time, I was not provided documentation confirming completion of a brake system diagnostic or a clear resolution path. Due to the extended delay without diagnosis, I no longer feel safe operating the vehicle. I am also concerned that prolonged inactivity without proper repair may have worsened the condition and increased risk of failure. Given the nature of the symptoms involving braking and vehicle control, I request review for potential safety-related investigation. Vehicle information: 2020 Chevrolet Malibu VIN: mileage:.

Antilock braking system.

The vehicle went into shift to park and will not turn off. This is a known problem with all gm vehicles that hasn’t been fixed or offered a warranty for. It’s dangerous and causes the car not to move shut off in traffic and drains the battery. My car currently isn’t working due to this issue and the repair to fix is too much with no assistance from gm for a known defect. My car was almost hit because of the car had to be towed because it’s unable to be moved.

I was unaware that when I purchased this vehicle that when the oil is low, the breaks go out and the break power booster shatters. The beaks have gone out on me 2x already and thankfully I’ve only had to replace the break power booster only once. Now once the oil is changed the breaks go back to normal, there is no grinding of any sort heard, so now going forward I pay real close attention to my engine, I listen and pay attention to the feeling and sound of the breaks, once the oil begins to become low knowing it’s time for an oil change around 40% is when I start to feel a bit of the difference in the breaks and I can feel a little bit of grinding, no oil light has come on at this time nor has the oil light or any type of signal has ever come on at anytime to let me know that it was time for an oil change. I’ve checked for recalls, I’ve checked message boards, mechanics have no clue about this problem, but at least my mechanic does now!.

On December 16, 2025 the check engine light and service stabiltrek warning light appeared on my 2016 chevy Malibu hybrid. On December 17, 2015 I took the car the capital cheverolet service dept who has been servicing my car regularly for the past five years. They performed a complete diagnostics on my car that determined I need to "replace the ebcm with brake pressure modulator valve" and said it would cost over $2800. 00. Upon further research I discovered that the same make model and year was recalled under recall #39440. I also learned the my VIN number was not included in this recall. This is a safety defect that has rendered my car not drivable until I get it fixed. As a senior citizen on a fixed income I am unable to fixed. I would like to know why was my car not included in the recall and if its possible to get it on the recall list so it can be fixed.

December 12, 2025 I had to drive 20-30 miles an hour the car would not break I had to use parking break. When I would try to stop it would continue to roll. The pedal was hard! this is very dangerous and other cars have crashed there are also class action lawsuits regarding just this! vehicle vacuum pump the bill was $5200 I am asking for reimbursement! vehicle vacuum pump engine light on tire sensor light on saw there have been more cases.

My 2016 Malibu has a severe ebcm-related safety defect causing all four brakes to drag and overheat (reaching 240°f), leading to unstable handling. This condition mirrors the 2016 Malibu ebcm recall (gm recall 39440). I sought help from gm. A gm-certified dealer-monken in centralia, IL performed a “diagnostic scan” which documented the core hydraulic failure: a constant, uncommanded 6. 839 psi residual brake line pressure when the pedal was released. (a healthy system should be near 0 psi) this 6. 839 psi is actively forcing the brakes to drag. The dealer ignored their own scientific data and submitted a fraudulent diagnosis of ("rust buildup") to gm, which gm used to deny the claim based on mileage. “rust buildup” doesn’t create hydraulic pressure. Gm is aware of this specific, documented, quantifiable safety defect (the 6. 839 psi pressure) and is refusing to investigate it further. I stressed to gm that the vehicle wasn’t safe to drive and that I have a small child who has to ride in the car with me. Gm dismissed my concerns by stating the dealership won’t release my car unless its safe to drive. I then had to drive the car 22 miles back home with all 4 brakes dragging. I requested the full diagnostic scan report (that the mechanic confirmed he could provide me with when I dropped my car off there) numerous times and never did I get one. I informed them that I would be filing a complaint hadn’t I received it by a certain time. The new kid in service then did send me screenshots of a generic obdii scanner where I saw the 6. 839 psi. I knew what the issue was prior to taking my car to monken. I had an independent scan done prior. I only took the car there to comply with gm’s protocol to be eligible for assistance. I am requesting NHTSA investigate gm for failure to address a documented hydraulic control safety defect that causes brake dragging and overheating, which is non-compliant with safety standards. I can give further info please call me for further details.

Was driving on highway and starting to exit and my engine light came on and it alerted reduced engine power. I had to slam on my brakes but they were very hard to press and almost non existent and steering was also difficult. Managed to get car to side of road but due to very hard to non existent brakes I did graze a truck and damaged my rear drivers side fender. I am very lucky I didn’t get injured and was able to mostly miss the cars stopped in front of me. I also have the shift to park issue happen at least 4 times a week.

The brake booster unit, vacuum pump , brake light switch failed and malfunctioned and it is available. My safety and others on the road was at risk due to brakes being stiff and hard as a brick. Possibly nearly hit an other vehicles on the road. No warning lamps or other symptoms prior to the failure.

The vacuum pump for the brake assist is made from bad metal which can break and screw up the camshaft, chevy knows of this problem they have a recall for the 2017 model but not the 2018 which they both have the same exact problem, they need to take care of this it is a major safety issue, I have no brakes and it could potentially ruin my engine.

While driving the cars speedometer and all gages will stop working, or they will constantly move up and down on their own, it will also not accelerate to speed limit in a timely manner. . When stopping the car it will brake extremely hard on its own and throw me forward it will also give a warning message on the dash that the power steering isn’t working and to drive with caution. When parking the car and it is in park a message on the dash will appear saying shift to park.

Car suddenly stopped dead cold while driving on a highly driven road. No power. Several attempts were made to get off the main road and drive to a close neighborhood. Finally started and at every stop sign the car grinded during stopping and threw me backwards in driver's seat. Needed a tow. .

My car has been malfunctioning it keeps saying shift to park when it’s park and it show esc system issue and then the brakes stop working it has been going on and off took it to lou bachrodt Chevrolet and they couldn’t fix the issue. I have done research online and it shows the same.

Vehicle vacuum pump failed I have changed it 4 times now. Saw there have been more cases.

My 2016 chevy Malibu limited is experiencing electronic brake control module (ebcm) failure symptoms that match recall 39440, even though my VIN is not listed in the recall. Details of the problem: -the brakes would randomly feel like they were sticking and the car being held back -brake lights would remain on -car would float all over the road -abs and stabilitrak warning lights illuminated in the dash once. -abs and esc functions stop working, leaving only based braking available. -these failures occur intermittently but increased to everytime. -all 4 brakes are dragging, pulsing (no lights illuminated), reaching 240 degrees -confirmed by mechanic ebcm this is a safety hazard. The vehicle becomes more difficult to control in adverse conditions without abs/esc. I transport my special-needs child in this vehicle, and I am deeply concerned for our safety. Why I believe recall expansion is needed: gm has acknowledged this exact defect in recall 39440 (affecting other 2016 Malibus built during specific production dates). My vehicle is showing the same failure, and I request NHTSA investigate whether the recall population should be expanded to include additional vins.

Brake system failure lost brakes twice, went and got a diagnosis reading and it said brake system module failure. That it lost communication with the module.

The rear knuckles on these cars are constantly going bad and the parts are expensive and so is the labor. So we have to pay a fortune to fix a common issue that gm should be recalling and fixing for the people who buy these vehicles. It's crazy how common this issue is and it's still not recalled. If you hear a clunking/rattling noise coming from the back of your car then it's almost certainly a knuckle problem.
