The first problem with my car was the tire pressure monitor. The location of each tire was wrong on the informant section. Soon after purchasing the car when ever I would park the car would not shut off and the DIC would display Shift to park message. Around 6 months after the purchase the brake pedal was getting harder the press down on and within a week from that while driving home from work the car completely shut off in the middle of traffic. It wouldn't start leaving me stuck on a busy street with heavy traffic blocking use of the lane. After 10 minutes it started back up and I barely made it into a parking lot of a shopping center with it shutting off again before I can park. I had to get a tow. I didnt go to an authorized dealer. I took it to a certified mechanic and had to replace the brake vacuum booster. The motor had to be cleaned out due to broken metal that got inside. After that repair car seemed okay until March 2026. The car now is in high idle and struggles to pick up speed. The message on DIC says engine power reduced. On the freeway the car can be going with the flow of traffic then suddenly engine power is reduce rpms go up high and it drops speed struggling to pick up. I paid the loan $16,000 off using what I had saved. I cant go out and purchase a new or used car.

Year 2019, code P1101- vehicle hesitates while drive, will reduce power while driving, while sitting idle at a stop the car will die and I will have to restart the vehicle. Multiple times while driving on the highway at 70mph my car has all of a sudden either reduced power causing the car to jerk and shudder very hard or has lost all power completely and forced me to pull over while avoiding other drivers on the road. SOMEONE IS GOING TO DIE BECAUSE OF THIS!!! THIS NEEDS TO BE ADDRESS AND RECALLED ASAP TO GET IT FIXED. I am not in a financial spot to just go buy a new car and I shouldn't have too either. I'm scared to even drive 10 miles down the road to take my children to daycare/school because of how bad it is.

- started shutting shutting off at while in drive. - started having reduced power - started idiling high while driving - initially there was no codes - last night I drove, I put in drive gear but it was delayed so I had to keep moving from park to drive for it to full go into drive - the codes came P0325 P0505 P0507 P0700 P1101 P2714 After I was driving up an incline the car stopped moving forward and started reversing backwards. One other independent shop advised they were able to produce but couldn’t figure out the problem because no code were shown at the time. There has been many people having the same issues I started off with and I found the forum to file a report .

My 2019 Chevrolet Malibu has severe safety defects involving the engine, powertrain, and speed control. The vehicle will sometimes accelerate on its own with my foot off the gas, and other times it loses all power while pulling into traffic. This creates an immediate risk of a crash. Multiple diagnostic codes appear repeatedly, including P0299 (turbo underboost), P0101 (mass air flow performance), P1101 (intake airflow performance), and P0506 (idle control RPM too low). The charge-air hose repeatedly blows off the throttle body while driving, causing sudden loss of power. The vehicle was sold to me by a dealer as safe and reliable, but these defects appeared shortly after purchase. The unintended acceleration and sudden loss of power make the car dangerous to drive. This appears to be a serious mechanical and safety-related defect that could cause an accident.

The vacuum pump has a tendency of breaking and when it does it affects the exhaust camshaft making the car completely inoperable. When this happened my vehicle lost all brakes and power and would not start. This happened suddenly with no warning and left me stranded in the middle of lanes of travel. This is a well known issue with the Chevy 1.5 L and is documented in the TSB Bulletin #21-NA-268. The vehicle was inspected following the TSB number provided and diagnosing via the information provided.

This model of 2019 Malibu, does not have the function to shut off the auto start/stop feature. I have had the car for a few years and in the past year this feature has begun to malfunction multiple times at random. When in drive and approaching a stop sign or red light the Malibu will engage in the auto stop feature. There have been occurrences when after this is engaged and I lift my foot to continue to drive that the vehicle will not restart and be completely shut off. The dash will tell me to “shift to park” as if believing that I am in drive but that I shut off the vehicle. I will have to shift the vehicle to park and then push the on/off button to restart the vehicle several times. It has taken upwards of a whole light change cycle for it to be restarted. It is exceptionally dangerous as I am often in a busy intersection light with my vehicle unable to go. There is no obvious trigger and it occurs at random intervals. There is no option to turn off the auto start/stop feature and it is the only thing that causes it to occur. No warning lights or indicator has occurred. I have taken the vehicle twice to the dealership as well as another mechanic and they were unable to diagnose any problem or replicate the issue. Since it occurs at such unpredictable times they were not able to identify anything, however I do have a video taken of it occurring to me. The dealership said that GM has not seen anything like this, yet I have read about other similar issues online with this model. Safety is extremely at risk for myself and others as the car is essentially turning itself off while I’m in the middle of a drive and takes several moments to be able to drive again. This has occurred about 10 times since it begun and seems to be more frequent. I’ve replaced the battery and reset the BCM as two cautionary measures and neither has resolved the issue. I have a video of it as well but I can not attach to this form.

Vehicle was being driven at 60 mph on the highway when the brakes weren't responding as I was entering a sharp curve. Had to stand on the brakes and manually lower the gears to keep from hitting a tree head-on. Check engine light was on. P0014, P0017, and P0556 codes were pulled before having it towed to the first mechanic. Car wouldn't start after it was parked after the initial incident. The first mechanic was unable to diagnose so the vehicle was towed to the Chevrolet Dealership. They say the brake vacuum pump malfunctioned and caused permanent damage to the engine rendering the car inoperable and I will have to have a new engine installed. The car drove fine prior to the vacuum pump failure.

The clutch solenoid started failing without warning or notice. This was finally confirmed by a transmission shop after a warning lamp related to the issue finally popped up after months of issues. My safety was put at risk due to the sudden and intermittent failure to shift into drive. This would sometimes lead to the engine stuttering then shutting off while still in drive. Attempts for dealers and private shops to nail down the issue were unsuccessful due to the system not reporting or recording any information related to this failure to shift. Again the danger came intermittently and suddenly when, shifting from park to drive, shifting from park - reverse - then drive. It would cause my vehicle to “stall out” in an active lane of traffic. This issue occurs from probably 60,000 - 90,000 miles when the system finally threw P0700 and P2714 codes to point to the issue.

I have been driving this car for three years, and it performed exceptionally well until Friday, July 12, 2024. While driving on the highway, the "Engine Power Reduced" warning light activated. I pulled over, placed the car in park, waited a few seconds, and restarted the engine, but the issue persisted. Consequently, I took the car to the nearest auto shop, where they identified and repaired a throttle issue. On July 16, 2024, the car's brake system failed, preventing the vehicle from stopping properly. I utilized the emergency brake and once again brought the car to the nearest auto shop. The diagnosis revealed a broken vacuum, which was identified as a manufacturer's defect. My car is currently in the shop for the second repair due to these manufacturing defects, which have incurred significant costs. It raises concerns about the safety and quality of the parts used in the manufacturing process. Why are low-quality components being installed in these vehicles? This poses a serious safety risk.

Vehicle occasionally hesitates to accelerate past 1st or 2nd gear & produces no power until the turbo & gears finally kick in. Has put myself & my passengers (my children) in danger of traffic’s way while trying to merge into traffic from a stop. Have had to pull to the side until the car is able to go past 5-15 miles per hr. Have taken the vehicle for inspection to Chevrolet of Watsonville & the tech there was unable to replicate the issue & was told to take it back when present. The issue recently happened again late evening but then resolved on its own when I planned to take the following morning. The vehicle has horrible MPG ranging from 18-24MPG when the rated MPG is 27-36MPG. I don’t understand how I am supposed to resolve this issue if the problem doesn’t persist when I am able to finally get an appointment for the vehicle to get seen. This issue is very concerning & would like help as I am nearing the manufacturer 100k warranty expiration mileage. Also There are no service lights present on the vehicle.
