12/27/2021 I started my car to leave work & noticed a loud tap. I've worked for dealerships in the past & was part owner of my own repair shop for many years. Popped the hood, checked the oil level which was good, & figured I'd be fine to drive it home to park it & then hook the scanner up. Mid-way home I received an engine performance notification on my dash, but other than that it seemed safe with no diminished speed. Less than 3 miles from home I went to stop at a red light & had the hardest brake pedal I've ever felt in my life. I was fortunate nobody was around me so I put all the weight of my body on the pedal to stop the car at the light. The engine was sputtering & the steering felt tight & it felt like it was stalling, with a green turn arrow I risked crossing the highway & was able to safely park in the community's rec center. I'm not one who is quick to take anything to the dealership because many times the techs are lazy, so I hit the web & found two things. One - there is an extended warranty on the TPS sensor which is the entire gas pedal itself. This could explain the engine performance notification, but not the lack of brakes. Upon hours & hours of additional reading I found the problem - the vacuum brake pump. We ordered it & replaced it but I can tell you my engine likely needs an additional camshaft replacement for it to ever be right again. Two codes remain: P0014 & P0017 - Exhaust camshaft/crankshaft position not plausible. What was the condition of the vacuum pump? It was SHATTERED & had spewed chunks of metal directly into my engine. I was lucky that day, had I gotten 1/4 mile down the road I could have wound up in a lake instead of a parking lot. GM should be ASHAMED of this design & it's continued failure to not only address the issue, but lie about it in the process. First owner, failure occurred at 54,500 miles - no warranty. What scares me the most, is how many times the same owner has had this pump fail again & again.

I was driving around 50 MPH and the car began to sputter and it wasn't getting in gas. It slowed down to 20 MPH and I had to stop on side of road. It behaved as if it were out of gas, but it had a qtr tank of gas. It would not start after I stopped it. I took it dealership and they still do not have an answer. There should be a recall on this. Numerous reports that are similar to my scenario.

Malibu would not recognize shift into park. This happened multiple intermittent times. Had to take it to dealership to be repaired on 9/6/22. While waiting for my Malibu to be repaired I was talking with a gentleman who had his Malibu in for the SAME problem. He stated his friend had the same thing happen on his Malibu. I came home and looked up information on this problem and found it isn't just Malibu's and I learned that there is litigation about this problem in Michigan. Why has there not been a recall for this problem?

I was leaving the gas station and when I got ready to pull off into traffic the car stalled. Flashed a message saying the automatic steering was disabled or something drive with care. I go out this morning and it won't start at all. It cranks but won't turn.

My vehicle showed up on a Carfax report as being in an accident in Tennessee on 10/15/2020 when the vehicle was in Iowa on that date. The Chattanooga police report shows this VIN# on a 2002 Chevy Minivan owned by Enterprise Car Rentals with Colorado license plate 266XFH. My vehicle is a 2018 Chevy Malibu sedan purchased from Enterprise March 26, 2019. I do not understand why two vehicles have the same VIN #. Please investigate.

After parking car and turning off engine an error -€œShift to park-€ displays. Only way to resolve is to turn car back on, put in different gear and then back into park, or keep pushing shifter up while in park to force into place and get car to recognize it-€™s already in park.

Doors do not lock when put into drive. Also when putting into park, car dings and error comes on stating shift to park. Doors have not locked in over 2 years, however at times it does but as of now they are not locked.

The vehicle was sent into the shop for repair four times and I continue to get a shift to park alert on dashboard after the repairs and warranty has passed I was asked to pay for the repairs when the dealership has serviced the car for over a week each time stating they couldn-€™t find the repair light I have contacted gm about the issue this is an act of consumer abuse I would like to be contacted on this matter

there is a issue with the chevy mailubu where a message will pop up on the dash and say engine power reduced which will significantly slow down the speed of the car and is impossible to keep up with traffic as someone who has to use the expressway everyday with a toddler in the car this is a big issue also im wondering why this isnt a recall on the the malibu because i know three other people with the same issue and we all have different year cars. chevy service team said the issue was from a pcv valve that will cause the exhaust to clog up.

When the check engine light initially comes on, the car will go into "reduced engine power mode" which will decrease the power and speed of the car, forcing me to pull over and turn the car off and restart. This is a hazard to myself and other drivers especially when on the highway, driving at higher speeds. There has been an investigation in to GM where it was found that a few other models have this issue. This happens every time I have something repaired and the light comes back on, which has been twice in the past month. The first time this happened, I had the repair done and it was fine for a while. After the car has been off for a while and the light is still on when I start my car, for the most part the car is no longer in this mode, but it can come back on at any time.

We have had this car since 2020 & frequently the "reduced engine power" warning comes on & the car will not/or very slowly accellortate. Along with the engine light on.We have hooked it up to a computer many times but nothing solves the issue. Lately it has been staying on constantly. Huge safety risk as my two children are in the car daily & we do take main roads/highways! When this comes on, the car will not remote start as well, also this is random in doing so, it has came on when I 1st start the car in the morning, while driving at 35mph, stopped at a light, or turn on any time I turn the car on. Doing some research and many others have had issues as well as their engines giving out at 60,000 milles (ours is at 57,000) & nothing resolved for them either. This is a huge safety issue and needs recalled. Us malibu owners should not have to pay to get this looked at constantly nor worry about owing on a car that could give out at any given time. We keep maintenance up on our car and this is the only constant issue we have that cannot be fixed.

When the car shuts off at a red light and starts back up after u take your foot off the break, it has a stalling problem. Sitting at a light, the radio was still playing. Once it was time to drive and I took my foot off the break, the car was stuck. I had to turn the car off and turn it back on in order to drive it. That is very dangerous because I was in the middle of traffic. If the car behind me suddenly moved over the car behind them could have hit me from the back, I have a 5 year old in the backseat. This should be a recall problem. Other 2018 chevys have this problem as well but my model for some reason is not on the recall list.

As I was driving down the highway at 60 mph the road was clear at the time of any debris my car suddenly had two lights on the dashboard. On the left was the traction control light and the right side was the engine light. On my computer display was the words -€œreduced engine speed-€. My car suddenly slowed from 60 to about 30 mph in a matter of seconds. It was like I had slammed my brakes. This all happened simultaneously I attempted to pull over safety and turn the car off and restart it. The lights remained on. My car was not able to get over 27 mph There was no warning what so ever If anyone would have been behind me I would have been rear ended At this time I took it to a mechanic who put it on the computer it was coded at the pedal position sensor. He was able to save the code, clear it so I was able to drive the car and advised to drive it locally for a while in case it would do it again as it is unsafe. The closest Chevy dealer is over an hour away from my town and at the time of day it was not safe to drive the car to the dealership for confirmation.

Check in light is on. They told me it was something with the idle sensor the fixed it. Not even 24 hours later it-€™s back on they tell me it the vacuum pump & it cost 800 buck. I do some research and noticed on not the only driver with this problem They tell me I can still drive it but nobody told me pieces of the pump could damage the engine also so what do I do now

Vehicle is constantly telling me to shift to park when the vehicle is clearly in park. Also, the battery will die if this shift to park message isn-€™t resolved. I-€™ve already had to replace my battery twice and the dealership keeps telling me they can-€™t find anything wrong with it. After doing some research I see that this is a VERY common problem for the 2016-2018 Malibu-€™s and I feel very strongly that it should be recalled.

I always get rattling noise during gas paddle pressed while driving. Once I start put foot on gas paddle, rattling noise starts and when foot remove then it stops. it does not matter what is the speed and whether I am accelerating/de-accelerating. I visited dealer many times to fix this sound issue but not resolved by dealer. I observed another point which is during AC (Heater ON), sound comes but during AC (Cooler ON), rattling sound is infrequent i.e. sometime happens and sometime not. I am not sure from which part this sound comes but it is from Front Hood for sure. This sound I noticed when my car crossed 47K/48K miles in 2020.

Car displayed steering assistance reduced about 2 or 3 times whole driving and I wasn't sure what that meant because it popped up and disappeared so quickly. So a few days later it never appeared again. On this morning as I'm driving and come to a red light to make a left hand turn while waiting and taking my feet off the brake to go cause my light is now green my car turns completely off and I'm stuck at a intersection about 2 to 3 mins later it tells me to start it back up.

I do not know what component or system that failed or malfunctioned because I am not well versed on the different parts of an automobile. The problems started this past week around October 26, 2021. When the car is stopped at a red light or stop sign and I am ready to go and in the process of taking my foot off the brake pedal to move to the accelerator the car momentarily cuts off completely (no lights, inside or out, no radio). In the instant that it cuts off and I move my foot to the accelerator everything comes back on and at that point I can continue driving. I have noticed when this happens all programmed radio stations are deleted but the programmed stations return once the car has been turned off for a while and started again. I also noticed a message regarding steering assist, but I cannot get the entire message because it is only there for a second or so. In other instances which began around October 28, when trying to start the vehicle the message reads battery low start vehicle. I then try to start the vehicle a number of times before it actually starts. When it does start the message reads battery saver active. There have also been a message service stabilitrak. The engine light does come on from time to time and then goes off. I brought the vehicle in to a Chevy Dealership (Banner Chevrolet in New Orleans) and was told that a service technician would not be able to look at it and diagnose the problem for at least 3 weeks because of the backlog regarding COVID-19. I decided not to leave the vehicle at that time and will check with other dealerships.
