2020 Chevrolet Malibu

While attempting to enter a high-speed expressway, the transmission malfunctioned, preventing normal acceleration. The vehicle could only accelerate very slowly but managed to maintain a limited speed, creating a hazardous situation while trying to merge into fast-moving traffic. I was able to navigate the vehicle off the expressway, at which point the transmission completely failed and the vehicle died. The vehicle was towed to an authorized dealership service center, where technicians diagnosed a total internal failure of the CVT transmission requiring complete replacement. Mind you, the vehicle is under 6 years old and has fewer than 90,000 total miles, and this is the second time the transmission on this vehicle has suffered a total failure and required a complete replacement. Prior to this mechanical breakdown, there were no warning lights, abnormal symptoms, or performance issues indicating an impending transmission failure. The vehicle is currently available for inspection.

While driving, the brakes became hard and the vehicle was difficult to stop. The brake pedal required excessive force, brake assist was reduced, and the stopping distance increased, creating a serious safety hazard. The check engine light had been illuminated for approximately two years before the brake failure occurred. In January 2024, I reported brake-related concerns to a Chevrolet dealership while the vehicle was under warranty, but the root cause was not diagnosed. In November 2025, after the brake pedal became hard, an independent repair facility inspected the vehicle and determined the brake problem was caused by a failing engine vacuum pump. They advised that the vehicle be repaired by a Chevrolet dealership. By January 2026, the brake condition had worsened to the point that the vehicle was no longer safe to drive and had to be towed. A Chevrolet dealership later confirmed that the engine vacuum pump had seized and damaged the camshaft, requiring replacement of both components. The vehicle remains inoperable. The failed vacuum pump caused loss of brake assist, resulting in a hard brake pedal, reduced braking ability, and an increased risk of a crash. I believe this represents a serious safety defect because failure of the vacuum pump significantly impairs the driver’s ability to stop the vehicle safely. I understand GM has issued service information regarding vacuum pump failures on this engine, and I am submitting this complaint because I believe other drivers may experience the same dangerous brake failure.

May 7, 2026 National Highway Traffic Safety Administration 1200 New Jersey Avenue SE Washington, DC 20590 RE: 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:

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)

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.

When braking, the vehicle experiences a system failure. There is a loud impact, the dashboard shuts down, warning lights activate all gauges go to the left, and the vehicle loses power and enters a reduced speed mode before recovering. This has been ongoing and creates a dangerous driving condition. The dealership has had the vehicle over four months and has not diagnosed or repaired the issue. Please Note: I have attached the invoice sent to me on April 17, 2026, via email. The information in section 3 had been changed while I was sitting there. It originally state, engine repair needed. It said absolutely nothing about the reason I was there, which was what I am now describing. The description in section 3, has been worded incorrectly. It states I said, when coming to a stop, but it is not only when coming to a stop, but even if I am in flowing traffic and have to touch my brakes to slow down at any given time, there is a loud thump sound and a jolt, all of the dash lights come on, all the gauges go to the left, the warning lights are on and it has to sit there, not for a few seconds, but until those lights go back off and then it will move very slowly, until it decides to gain power. You have no warnings as to when it will happen or when the car will regain speed when it does happen. I gave pictures of the dash on April 17, 2026, as well and these pictures have the date December 31, 2025, on them. As I was having the issue while driving it to the dealership for repair. The invoice mentions [XXX] . I do not know her and have never met her. I only spoke with a man. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Reduced Engine Power Light: The car limits acceleration, often accompanied by a check engine light. Stalling or Hesitation: Engine stalls or acts sluggish when accelerating, particularly in traffic. Limp Mode: The vehicle restricts speed, making it difficult to accelerate. The car stop working in the middle of the freeway and I was in the car with my child when it stop acceleration all gages in the car were going crazy, car was shaking bad finally car turn off. I was able to make it to the emergency lane of the freeway. There's similar complaints for 2020 Chevy Malibu but no recall has been done. Per my research it looks like a lot of this type of vehicles have problems with throttle body causing Engine stalls. Do the right thing and open up a vehicle recall, thank you!

Several things have been going wrong with this car. I have only had it for about 7 months. Minimal driving. Got the car with 84,000 miles and it now has 88,000 miles. About 2 months ago the check engine light came on. Got it into a shop and they said an oil change may possibly help with this. Got the oil change, cleared the code, drove it around and check engine light came back on. Brought it back to the shop and now the entire valve cover needs replaced. It’s been about 2 weeks since then haven’t had it fixed due to low funds. A couple days ago I was driving with two [XXX] olds in the car and was at a stop light. After about a minute the cars engine turned completely off lost all power including the center screen that displays your settings and radio, all lights, and the screen behind the wheel all with my foot on the break at a stop light. Due to this situation I was unable to turn my hazards on to alert the cars coming up being me at a green light absolutely panicked that we were going to get into an accident. A little while after the car turned back on, but unfortunately when trying to push down on the gas pedal nothing was happening. No revving sound and no movement of the car. Car still in drive. A police officer pulled up behind me to check if we were okay. He stayed to keep us safe until people came to push the car off to the side. During the push the wheel was almost completely locked up as well as the breaks. This is not the first time the breaks have locked up on me. Next day we got the car to a safe area to be parked. A couple days later went to try and turn the car on and immediately the car is shaking violently and making horrible noises. The car is unsafe for me to drive and unsafe for people on the road. This car is completely unable to be driven now also due to the horrible shaking. No recalls were found under my VIN, but all of these signs seem to be a problem for other people.

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!

This is a 2020 Malibu with only 18,000 miles on it now. We are having intermittent loss of power. Car will be moving fine when suddenly it looses power when pulling into traffic from a stop. It has also happened on the highway(right after leaving the dealer service department) when going to pass a vehicle…all of a sudden power drops and rpms go up and car slows up. When it suddenly happens, pulling into traffic is very slow. The only way to get power back is to turn off traction control via a button. It is back at the dealer now. They have had it the last two weeks. They fixed a shift to park issue but cannot duplicate the loss of power. So they are saying it is ready to pick up. Once, recently, a check engine light come on along with a message saying something like low power mode. We went straight to the dealer with the vehicle. They had the car for three five out of six weeks and were able to duplicate the loss of power once. We wanted them to contact Chevy to help resolve this, but we are unsure if they actually did. These problems first were serviced in April of 2024. This car is very scary to be in, the way this happens and when it is happening.

Problems with my transmission for over two years, I’ve searched the website and have taken it to a dealership since. The vehicle has had a hard shift and problems to accelerate. The issue continues to get worse and my car has stopped while in drive, only allowing me to go backwards. It was within warranty and low miles. I was told that that’s what new cars do. Transmission fluid has always been full and topped off. In order to know what is wrong I am told I would have to pull my transmission and was suggested to replace it because it would be an easier fix. The steering also pulls. I’ve contacted the dealership and was told to contact Chevy for recall and since it was not in their data they could do nothing for me.

Put the car in drive and it sounded like a bomb went off and the car jerked very hard. Every light on the dash came on. The car did not want to go…when shutting off the car it says it is NOT in park and it is.

For over a year now my car has been giving me the SHIFT TO PARK warning when I am in park. Happens several times a day, every day. Seems to be taking longer for the warning to shut itself off and allow my to turn car off and lock. Im not sure if my car is included in the recall but if it is NOT then it needs to be added as I am suffering on a daily basis with this issue. I am a single mother and cannot afford to miss work due to this and cannot afford to attempt to fix issue out of my own pocket. Please add my car to the recall list and help me fix this issue.

My car is displaying a "Shift to Park" message on the dashboard even when the shifter is already in the park position, preventing the vehicle from being turned off and potentially leading to a dead battery or the vehicle rolling away. The "Shift to Park" issue poses safety risks, as it can prevent drivers from turning off their vehicles and potentially lead to unintended movement. This issue is getting worse everyday.
