Vehicle cuts off daily. This has been going on for months. A message shows up saying put the car in neutral to restart. Battery and alternator have been tested more than once and they are not the issue. The car cut off while I was in traffic driving across a bridge! I had to get help pushing the car to the side of the road. This particular time the car would not start back up without a jump. Majority of the time while at a red light, it cuts off. After replacing rotors, brake pads, and brake pump, braking is still rough with screeching and grinding leaving lots of brake dust on the wheels. At times the brakes go all the way down.

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.

On September 28th I was driving along the highway, went to take an exit, and the brake pedal was locked. I experienced a loss of braking, hard brake pedal and increased stopping distance. In order to get the car to stop, i had to put the car in neutral and coast into a ditch/grass. Before the brake failure there was no instrument cluster malfunction lights illuminated or any warning of imminent failure of the vehicles braking system. A mechanic has informed me that the vehicles brake vacuum pump is to blame and that it needs to be repaired immediately. This part suddenly failing with no warning caused a complete brake failure within the car and posed a risk of injury or death to me and others.

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.

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

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.

I was stationary at a red light on highway 49 with my foot on the breaks, and when the light turned green I let my foot up off the breaks and the car just shut off. I tried to turn the car back on, but still nothing. I waited a few seconds and the car started back up, so I put it in drive and started driving, but when I tried to slow down the breaks were very tight. For an hour and a half, I sat there and tried to figure out what was wrong with the car. I found nothing, so I got back into the car and cranked it and the check engine light came on. I got the car to star Chevrolet and they diagnosed the problem as the brake vacuum pump.

Couple days ago we had to tighten the lug nuts on the car front tires. Its was good a couple days and now again doing the same thing..
