| Jul 2024 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER,ENGINE | REDUCED POWER TO ENGINE . Previously had recall for this issue, which was replaced by Chevy service center. About a year later I had the same problem but had to pay out of pocket because there were no active recalls on the issue. As of today, I am receiving the same “REDUCED POWER TO ENGINE” error and check engine light keeps coming on. This happens randomly but frequently almost every single day. Error will shut off after restarting car and then happens again not long after. I’ve had this issue with multiple Chevy Malibus that I have owed and there is currently a class action lawsuit against GM for this exact issue. | Crash: No Fire: No | Unknown |
| Jul 2024 | ELECTRICAL SYSTEM,BACK OVER PREVENTION | This car has the shift to park issue that was under a recall for 2016 to 2019 chevy malibu. However gm refuses to put my vin in the system so this issue can be repaired. This is a 2018 malibu which should have been on that recall list. | Crash: No Fire: No | Unknown |
| Jul 2024 | UNKNOWN OR OTHER | To whom it may concern, Chevy has had major recalls on their “shift to park” error. This is a very common recall according to much research and they are refusing to fix mine. They are claiming my vehicle is not one of the recalled. However, I’ve found many others across social media and Internet forums that are experiencing the same error. When parked my car will say “shift to park” even when it is in park. I am afraid that this will cause major issues with my vehicle. | Crash: No Fire: No | Unknown |
| Jul 2024 | POWER TRAIN | The contact owns a 2018 Chevrolet Malibu. The contact stated that after shifting into park, the message “Action Required Shifting to Park” displayed. The message remained displayed even when the vehicle was turned off. The contact restarted the vehicle several times while slightly moving the gear shifter until the message was no longer displayed. The failure had become constant. The dealer had been contacted and an appointment was scheduled. The vehicle had not been diagnosed or repaired. The manufacturer had been made aware of the failure. The failure mileage 67,000. | Crash: No Fire: No | 67,000 |
| Jul 2024 | VEHICLE SPEED CONTROL,FUEL/PROPULSION SYSTEM | car pauses after stopping at lights and stop signs and in stop-n-go traffic and won't go as soon as gas pedal is pressed. It hesitates then jerks forward once the gas is activated. Check engine warning is for stop/start transmission accumulator sensor! Cost to repair over $1300 and seems to be the same issue seen in thousands of 2018 malibu's that have been recalled??? My car does not show an active recall??? Chevy rep Andrea at 1-800-222-1020 said sorry no recall for your car and to contact you with complaint? This issue almost caused my wife to have accidents after the car lurched forward after stopping. We were also beeped at many times as cars behind us were frustrated we could not move for 10-20 seconds after stopping! [XXX] [XXX] [XXX] Car is being repaired now by Belise Chevrolet Warwick RI 877-553-0957.

| Jun 2024 | POWER TRAIN,ENGINE,FUEL/PROPULSION SYSTEM | Car hesitant to crank, once the Start/ stop button is pushed, the car will start, run smooth for a second or two then start to shake and putter like it’s not getting fuel and loses it power and cuts off. I have to go through this process 5/6 times before the car will stay crunk. While driving Car will out the blue say reduced engine power and acts as if it does not want to pull or it is losing power! The car also has the eco saving feature where it cuts off at every stop and there is not an option be turned off and car is hesitant to start back up after it cuts off. Car is now starting to smoke from the tailpipe. The VVT intake and exhaust solienoids have oil getting into them and the PCV valve is about to crack open. The car throws codes like rich fuel intake, something to do with the catalytic system (in which I’ve put a brand new catalytic converter on the car and it did not solve the issue) it also throws codes about a throttle and cam sensors and a few more codes.. I see where there are recalls for the (same make, model,year, and engine size) but my cars VIN is not included with the recall! Can we please get this as I need my car and need this issue fixed as soon as possible as it is dangerous for me and my 2 year to travel in this vehicle. | Crash: No Fire: No | Unknown |
| Jun 2024 | SERVICE BRAKES,ENGINE | Driving normal. Upon application of brakes, brake pedal became stiff and brakes did not function normal. Had to apply immense pressure to stop and it sounded like brakes kept locking up. Vacuum pump that supplies vacuum for engine with turbo to function, along with the brake booster to be able to apply normal braking power, was destroyed. The inside of the vacuum pump is in pieces and part of the bushing that connects into the engine was broken. Caused by faulty vacuum pump, or faulty cam shaft. If this had happened while in traffic, it is likely a crash would have happened. Damage caused to the vacuum pump resulted in metal pieces in the engine block as well. | Crash: No Fire: No | Unknown |
| Jun 2024 | UNKNOWN OR OTHER,SERVICE BRAKES | Car does not recognize when the shift is on park. States to put car in park despite it being in park. Could take up to 10 minutes for the system to finally recognize the gear. | Crash: No Fire: No | Unknown |
| May 2024 | ELECTRICAL SYSTEM,VEHICLE SPEED CONTROL,ENGINE | Since I got the car, if I let it go in auto stop, it has a hard time accelerating when I push the gas. It has gotten worse and now it has a hard time accelerating in general. When I push the gas it sounds really loud like it’s struggling to go. I realized this is a safety issue for me and others when my car wasn’t going at the light of a busy intersection, or when I’m getting onto a highway and my car isn’t picking up speed. This makes it scary for people already on the highway as Iam causing them to brake unexpectedly. Every time my check engine light comes on I take it to the dealership. It’s been taken in for repairs multiple times but this issue still keeps coming back. | Crash: No Fire: No | Unknown |

| May 2024 | ELECTRICAL SYSTEM | My car keeps saying please put in park, even after the car is parked. If I don’t turn on and off the car multiple times shifting from park to reverse to get it to not say put in park, my lights in my car stay on and the battery will eventually die.

| Feb 2024 | SERVICE BRAKES | I was driving down the highway and took the exit and went to hit the brake pedal and it was hard to push down. Took it into a shop for diagnosis/repair. Mechanic found that vacuum pump for brakes came apart. There is currently metal in the engine that I cannot afford to fix after already paying $500 for the new vacuum pump. | Crash: No Fire: No | Unknown |
| Feb 2024 | SERVICE BRAKES | I was driving my small child to school and my car had a service message pop up that said engine power reduced and then my brake pedal became stiff to the point where I could not push it down at all to stop at a red light. Luckily by quick thinking I push down my emergency brake to avoid from hitting other cars. From doing research this is not the only complaint about this same similar situation on this car (2018 Chevy Malibu LS) It's ridiculous. It's going to cost me over $2000 for parts and for labor. | Crash: No Fire: No | Unknown |
