The electrical system was refusing to acknowledge that my car was in Park & kept giving me a -??Shift to Park-?? message on my dashboard. Took 3 or 4 tries of starting & shutting off the car for it to go away. Took the car to the Dealer & turns out that a faulty shifter was the problem. The gear shifter had to be replaced, but not the shifter harness underneath the shifter.

When you park the car and shift the car into park a message appears on the dashboard stating "Shift to Park" the car does not think it is in park and is telling you to put it into the Park Gear to turn off the car. You can not shut off the car as long as this message is displayed on the dashboard. Sometimes turning the car on and off 5+ times may get the message to go away but as time has gone on it has been harder to get the message to go away. At times we have been stuck in the car for over 10 minutes trying to shut off the car.

I have no Brake Lights when applying the Brakes and cruise control no longer works due to Service ESC message on display. I was advised by replacing the battery this would clear the ESC but it did not. I believe the service ESC message is tied into the brake lights and cruise control not working.

This car is displaying a shift to park on the dashboard. I have read several complaints and even lawsuits filed about this matter on the internet. Why hasn't this been recalled to fix on these vehicles it drains the battery and you aren't able to put the vehicle in park or lock the doors or anything

After shifting into park and turning off the car, a warning message to shift into park comes up. Pressing on the button on the shifter several times eventually gets it to stop.

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.

When I shift the car into park the computer does not register it is in park. Still says place vehicle in park when you open a door. Have to shift it several times before it will read in park. I took it to the dealer and was told it is a common issue. They bent a bracket forward and got it to read for now. The tech said its a poor design flaw and GM should be replacing the sensor bracket but refuse to issue a recall on it.

Vehicle goes into near stall instrument panel goes as if you were starting the vehicle gauges go up down then back gas gauge said no gas on full tank, brakes felt as if was gone abs system not responding, engine rough, road had minor to moderate pot holes "Rawsonville Road" when stopped vehicle while running gave msg put in park to shift., vehicle was in drive once put in park it would not come out of park or realize it was in park. the issue i have been able to determine so far is on the vehicle fuse panel under hood it is connected to the main service disconnect for the entire wire harness "pin connectors male and female over 30 pins, it is held by 2 locking handles all with plastic tabs for the latching, this is failing under driving conditions and coming loose enough to separate contact from 1 or more pins normally on the drivers side. to fix the issues I had to disconnect the service disconnect and reconnect it while securely fastening the handles verified correct and happened again on testing down a dirt road service appointment is thursday -9-7-2022 at mark chevrolet in wayne michigan, i contacted gm and they said it had to be fully tested through a dealer i informed gm this is a major issue and not something i will be paying for it is likely a recallable issue i have seen alot of issues with malibu 2019-2022 having similar issues and are likely caused by the same issue if using this same service disconnect and fuse box likely nullifying the TSA's used for shift to park etc as others have stated and documented those issues repeat. the vehicles modules lose communication with the vehicle via intermittent service disconnect on the wiring harness. "network errors " support this via obd code reader as well as the powertrain hard fault code and the various pending fault codes prior to having to physically disconnect and reconnect the service disconnect fully to restore vehicle function and bring to safe location instead of on side of busy road

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 -??cannot 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.

-??Shift to Park-?? message appears on dash information screen and prohibits the vehicle from fully powering off and can cause battery to fully discharge. This appears to be a known problem, as referenced in GM TSB 19-na-206.

Unable to leave vehicle because the car thinks the gear shift is not in park. The car is actually in park. I-??ve tried wiggling the gear shift, turning the car back on several times and putting into gear and back in park. Nothing seems to work and it goes off whenever it decides to go off. This is causing a safety issue for me personally since I can-??t leave the car. This started about 2months ago.

The throttle body charge pipe popped off there was a recall that on this car says it-??s fixed. We replaced o ring and clip on charge pipe drove car. When we sped up to pass a car the charge pipe popped off car shut off. We had to push the car out of traffic. The car would not start. Error code check engine and engine power loss. Three hours under a Houston TX bridge got a tow. Only to be told that the gasket and clip needed to be replaced. Replaced again gm parts, car still can-??t go up hills or sped up. Charge pipe will pop off. The throttle body was checked and the lip on throttle body is still good. But there is too much oil build up on throttle body it appears and the charge pipe can-??t stay on. Causing engine failure. This almost got us killed on the highway. Very unsafe please help.

The contact owns a 2019 Chevrolet Malibu. The contact stated while driving 65 MPH, the check engine warning light was illuminated, and the fuel gauge reflected EMPTY even though the tank was FULL. Additionally, the speed gauge was not operating correctly, and the temperature gauge was not functioning. The contact also stated she depressed the brake pedal to the floor but failed to stop. The contact stated she used the parking brake to stop the vehicle before it seized. The contact stated when shifting gears to park, she heard an abnormal noise and the vehicle began to hesitate.

Unknown car shutdown without warning an will haste when given it fuel.

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.
