general problems of the 2019 Chevrolet Malibu - part 1

The brake booster vacuum pump went out in my car it broke which caused hard breaking while driving vehicle. When the brake booster vacuum pump broke a piece of it damage my camshaft as well as my timing chain in my motor.

- 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 .

Was driving on the freeway maneuvered over to exit vehicle lost power and engine completely shut off while in motion. Same incident occurred while on surface street as I was approaching a red light vehicle completely shut off while in drive and in motion.

Throttlebody hose pops off of the throttlebody due to a missing gasket ring as well as the retention clip/spring clip. The plastic pieces on the spring clip have popped off since the issue has been presented. Cannot accelerate past 3 1/2 rpms without throttlebody hose popping off from the pressure produced by the turbo charger.

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.

Vehicle stalls at lights and in traffic because of the start / stop system gm has put in this 2019 Malibu. This is dangerous as the vehicle moves if on incline (sometimes backwards). There is no control. The vehicle then has to be shifted into park and then restarted. This happened July of 2024 and August 2025.

When I put my car in park and turn it off, I get the message to "shift to park" my engine light is on and sporadically goes off. It is difficult to bring my car in as there is a fee to evaluate my car and the sporadic engine light. When it is on my chevy app tells me it is engine and transmission - air induction system.

The part in the linked article which was recalled, was never replaced. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

The contact owns a 2019 Chevrolet Malibu. The contact stated that on two occasions while driving 35 mph, the vehicle lost motive power. There were no warning lights illuminated; however, the contact determined that the failure was due to the throttle body. The vehicle was repaired. The local dealer was not contacted but had not diagnosed or repaired the vehicle. The manufacturer was contacted, and informed the contact that the VIN was not under recall. The failure mileage was approximately 96,000.

Car was running fine then next day wont turn over. Code reader said fuel injectors weren’t injecting fuel. And ecm failed.

Brakes got hard and reduced engine power came on and now won't crank went to the dealership and then they charge me 389 for a battery and it still didn't work they say it need a new motor.

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.

My vehicle has been having issues for the past 2-3 years with its engine acceleration, the bcm and ecm are faulty and or my fuses continue to fail, my check engine comes on with a service esc, power steering depleted, shift to park, and a service security system warning.

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.

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.

The car consistently says shift to park even after being placed in the park position. The car won't cut off. This has been an ongoing issue for around 1 month. I read online that this is common in chevy. There should be a recall.

In December 2024, driving to work when car abruptly stopped (no power). Waited for a while for my husband to arrive. Vehicle started again, drove to tropical chevy at 8880biscayne blvd, miami shores, FL for diagnostic testing (paid $160. Result - transmission problem estimated at $1,800). Did not have vehicle fixed. Decided to have vehicle examined again in September 2025; paid $160 diagnostic fee, estimate a whopping $8,400!!!!! did not have car fixed.

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.

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.

This is ongoing. Originally got trouble code p0239 after check engine light, cleaned throttle body. It went away. Then I got the same symptoms as a result of the throttle position sensor. I replaced that as well. Then I got a code for the turbo boost sensor. So I replaced that. Now I'm getting similar symptoms and the check engine light isn't turning on at all. I suspect maybe a catalytic converter, ecm issue, or transmission issue. I've repaired all problems that have given me a code. The car accelerates very slowly, while the rpms go up normally, then the car bolts off almost normally for a while. And becomes jerky. So I'm unable to safely pass others if needed or accelerate normally both from a stop and while moving. While driving at low speeds with the window down I can hear a sound that could be the turbo spooling up or maybe a fan. Also, the cooling fan will stay on for a while after turning off the engine. I contacted the dealer and they said the only recall is a cac retainer and told me there were no other tsbs open for my VIN but I believe by car is eligible for multiple including but not limited to 19-na-058.

Gm 2019 Chevrolet Malibu - report shift to park issue - mileage 13,784. I would like to report a shift-to-park problem I had with my 2019 Chevrolet Malibu. Approximately two weeks prior to this service call I started experiencing a problem with engine start/stop button and “shift to park” message on instrument panel. Pressing start/stop button would not turn off engine. It took several attempts to completely turn off engine. Two weeks and issue was getting progressively worse. Finally on Wednesday, March 29th and having started driving errands, I could not turn off engine at all. I could not get out of the car without warning beeps going off. I immediately drove to dealer service as I felt unsafe to drive. Dealer service performed and I picked up car on Thursday, March 30, 2023. They replaced shifter switch and installed jumper harness. Again, I do want to report issue as this car has only 13,784 miles. Thank you,.

I purchased a 2019 chevy Malibu on April 9th 2022. Car seemed to be fine at first drove car for two month experienced frequent shift to park issues as car would not recognize itself in park until multiple attempts at parking. I was arrested on June 4th 2022 and came home on September 5th and attempted to start my car. Car cranked multiple times before starting stalling and cutting itself off while display engine power reduced and check engine light. I used obd computer and car codes p0014 p0017 p0556. Vehicle was taken to hertrich chevy of salisbury maryland. The technician informed me that I needed a engine replaced due to nature of damage upon diagnostic chevy discovered vehicle had little to no oil (which is still puzzling oil life sensor in car is still reading at 22% and check oil light never came on not once for it to be a cause of no oil in vehicle. Was asked to present receipts for service and oil change of a vehicle I drove for maybe 2 months max prior to my incarceration and no one had driven my car during this time as the key was in my possession during incarceration. Problem occurred at 59,898. I purchased the vehicle at 54054 miles on the vehicle starts and has and extended crank and codes p0014 p0017 p0556. Most vehicles require an oil change at 7000 miles and still had a good amout of time before reaching that mark. Vehicle states that it is still under powertrain warranty until 60000 miles. However it's states that it is not covered if improper fuel or lubricant levels (oil) are the cause which is puzzling also because this is apparently a known problem with chevy vehicles as they have provided a bulletin on NHTSA website as to how to diagnose and fix the issue. Service bulletin #pip5598c or google the pdf bulletin. Chevy is sticking me with a known problem their engine does with the cost and replacement of a new engine. As well as losing the 7000 dollars I put down on my newer used vehicle. As well as it being a safety hazard and stalling randomly.
