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,

Before my car gave out I was having braking issues and my car wouldn-€™t accelerate when I pressed the gas. Then later that night I was driving home with my mother and fiancée when my car illuminated -€œengine power reduced-€ and my check engine light came on. When I tried pulling over I noticed that my brakes were very hard. So I had to roll from the speed of 45 mph until my car eventually stopped. I was not able to stop at the stop sign so I just had to blow my horn to alert other drivers. Whenever I took it to the dealership they told me my brake vacuum pump exploded and blew shards into my camshaft. The repair was 1700 for the replacement of the brake vacuum pump and the camshaft. I talked to the mechanic afterwards and he said that this problem has a good chance of happening again because the part itself is defective and there are no other aftermarket parts to replace it. Then I go to pick up my car three weeks later, and was told that my engine should be replaced because a cylinder had no compression. The price of that was around 5000.

Numerous times while driving my car both my son and I have experienced the same issues. Trying to get on the highway and pressing the gas pedal the car isn-€™t responding appropriately to the level of which the gas is being pressed. It isn-€™t accelerating appropriately. Than at stoplights or just trying to make a left hand turn from a stop position. You take your foot off brake and press the gas to go and it rolls a bit and you-€™re pressing the gas to go and the car isn-€™t responding. It-€™s just sitting there. Like paused. Then all of a sudden the car engages and takes off. It is very dangerous to not have the car respond to pressing the gas. And I don-€™t want to get into an accident because I-€™m trying to make a turn and get hit cause I-€™m just sitting there. Rather than it going when I-€™m pressing the gas. I am not getting any codes popping up on the dash. So the dealership has nothing to look at other than me saying this is happening to me and my son. I-€™m finding issues similar to this on previous models. But nothing on the 2019 that I can find. And with no error codes registering. But the issues occurring is highly concerning to me. There isn-€™t just one date this has occurred. This has happened now many times over the last 6mos.

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.

Driving along the interstate the car suddenly lost power. I was able to pull over and restart car and drive like nothing ever happened. Then once I parked the car at my destination the car would not start 10 minutes later leaving me stranded in an unfamiliar city. When trying to start the car it would click and the DIC would display Batter Saver Active following EMS following Power Steering. No check engine light was on in the vehicle before this incident. I was stranded in an unfamiliar city with no one around to help. After asking a random stranger for a jump the car started and allowed me to get home. No dealership can convey the problem with the car, everyone says there's nothing wrong with it. I have had the vehicle for about one year now with no problem up to now. The car often backfires and even completely cuts off at red lights (not from the auto stop feature). This is dangerous.

Numerous accumulated problems, all have complaints already on NHTSA site here. First, Start/Stop malfunction, when it is active when stopped vehicle will stall when it tries to restart when you take your foot off brake and it-€™s troublesome to restart at times, when that happens lights on dash all come on (warning lights) and radio/entertainment resets as well. Second, the traction control light on dash is on. The warning displays to have traction control system serviced, cruise control is disabled as a result, it-€™s been to the dealer for both above problems the start/stop problem they say they can-€™t get car to duplicate although it happens to us almost daily if not numerous times per day. This morning driving home from work the intake charge tube that attaches to intake keeps popping off and engine goes to reduced power mode on highway or wherever driving not safe at all. Saw a voluntary recall from GM going to contact dealer about tomorrow when open. Stereo resets often, completely shuts off and resets while driving at random. I also get the rushing/sloshing water noise other people have reported as complaints when coming to a stop, I read in forums that it-€™s something to do with low coolant but not low enough to turn on low coolant warning light. GM really needs to address this stop/start and traction control needing service light problems as I read all over the internet of owner-€™s complaints of same problems I have. Dealerships don-€™t want to do anything with the cars unles the issue a recall because it comes out of their pockets. So many complaints I read owners keep reporting that dealer -€œcannot reproduce identical problems-€ because they don-€™t want repairs coming out of their pockets only out of GM. I-€™m going to start filing formal complaints with GM until they get tired of hearing from me and fix some of this stuff or deem it a lemon and get rid of it finally.

The turbo charge pipe keeps popping off while driving and the car loses power.

- Temple , TX, USA

While sitting at stop lights the car has shut itself completely off and restarted itself. This has happened atleast 6 times in the past 24 hours. The first time it happened, a message was on the dash screen that said "corrupt......" with an explanation mark. I was unable to catch the full message. No message has displayed since that I believe. The vehicle shows no history/issue in the mychevy app.

While I was getting on the highway during acceleration there was a loud popping sound which was immediately followed by the check engine light turning on the airbag system warning light turning on and a reduction in engine power. I had to pull off to the side of the highway and pop my hood in which at that point I observed the air intake hose had popped off of the throttle body. I put it back on and attempted to continue to drive but it popped off again which caused me to take it very slow ride to the closest dealership. Once I arrived I had it checked out by a service technician and was advised that my throttle body needed to be replaced and so does my airbag clock spring which controls the airbag system, it's deployment, the horn and all of the steering wheel controls. Without this being operational I cannot blow my horn and the airbags may not deploy or malfunction in the event of a crash. I looked online and found out that this was an existing problem with previous models of the Chevy Malibu specifically 2016 to 2018 models.
