2020 Chevrolet Malibu Complaint Log

Engine loses power while driving. This happened the first time on 8/24/21 I was on the NJ Parkway in highspeed traffic . The vehicle would not drive over 25 miles an hour putting all occupants in the car at risk. The dealership repaired the vehicle The same loss of engine power re-occurred on 3/12/22 while driving at over 50 miles an hour. the car just slowed without warning, and I was unable to increase speed on a busy roadway

Shift to park error

I need my pistons and rings replaced. My car only has 57,000 miles. My car has been diagnosed with excessive piston blowby from 2 different independent service centers. Both times I have been to Chevy to get it fixed under warranty, they’ve charged me $200 for diagnostics each time and told me it is my PCV valve that needs fixed. I had them fix my PCV valve and I still have excessive piston blowby. Chevy just wants to keep bringing my car back in for more diagnostics. I have spoken with GM customer service 2 times and somehow every single time I give them my VIN they hang up. My car is a 2020 with only 57,000 miles on it. There’s absolutely no reason why I should need all new pistons and rings and why Chevy service centers won’t just get it done! I have diagnostic reports, receipts, and videos of everything.

This issue started at approximately 19,500 miles. While accelerating to enter a highway or to pass a vehicle going less than 55mph on a two-lane, Service ESC light appeared on dash. Loss or power was also immediate and if I tried to accelerate to maintain speed, engine was very rough in responding with no acceleration. Engine continued to run. Within 30 seconds or so, acceleration is restored, and check-engine light was flashing. Check-engine light stopped flashing after a minute or so. Initially, this only occurred occasionally during fast acceleration as mentioned above. Lately this has happened during continuous acceleration, such as using cruise control, while climbing a low incline hill (~15˚). Over the past year or so, Chevy dealer has replaced, pistons, fuel injector, and did a carbon cleaning of engine. No solution yet.

Sometimes when I drive my car it loses power especially when I’m turning into on coming traffic it will lose speed and I’ve almost been hit on numerous occasions. I’ve taking the car to Chevy dealership 4 times already the last time they discovered transmission issues they repaired it. They tell me they don’t see anything else wrong. I have read reviews from other owners and they are experiencing the same exact problem

The contact owns 2020 Chevrolet Malibu. The contact stated while driving 50 MPH, the vehicle started shaking and inadvertently decelerated. The contact stated that the Service ESC and check engine warning lights were illuminated. The vehicle was not taken to a dealer nor independent mechanic to be diagnosed. The manufacturer was not notified of the failure. The failure mileage was approximately 19,000.

Was traveling at about 58 mph down the highway when all my warning gauges starting going off. My digital dash went blank and the car started accelerating on its own. I kept hitting the brakes trying to make it slow down and I could hear the abs function and feel it thru the brake while trying to slow down. After about a 1/2 mile of fighting the car the dash turned back on the check engine light stayed on and the car stopped trying to accelerate but wouldn’t change gears and was stuck at 3500 rpms when I limped it off the road and had a tow truck come get it.

P0556 code and brakes are hard to stop. 40,016 miles on the car

I purchased a 2020 Chevrolet Malibu with 38,000 miles. I experienced a faulty air vacuum pump (first experience was at 45,000 miles and was replaced in August of 2021, two months after purchasing the vehicle in June of the same year), and then the replaced air vacuum pump again in February of this year (2023). This issue being brake related was unsafe. I experienced an intermittent reduced engine speed message on dashboard, with immediate reduction of speed down to 20 mph or less while driving. This made me and others unsafe. I experienced brake booster failure, among other issues stemming from all aforementioned. The car is now said by dealership to have indication of an internal engine issue and affected PCV lines dealing with a defective orifice (Kiriacopoulos, et al. v. General Motors LLC, Case No. 2:22-cv-10785, in the U.S. District Court for the Eastern District of Michigan) The car remains at a dealership and has now been there for over 30 days. There was no warning lamps, messages prior to the air vacuum Pump/Brake booster issue. I got in the car to try driving, and it was hard to push the brake with foot, so for I knew something was wrong. In taking it in to service, was when it identified to be that issue. Those issues have been manufacturer inspected (dealership) and confirmed. I experienced these issues since purchasing the vehicle in June of 2021. I believe that GM knows of these issues and has put me at risk on the road, along with some other symptoms of the car failures that are also well documented, and that GM is aware of, with no recalls. These car parts/issues put me and others in further danger, the car's air vacuum pump and brake booster affecting car's ability to operate, damaging other parts (Johnson vs. GM).  Consumer rights to be protected and safe are at risk, not deserving to have faulty auto parts sold, further exacerbating issues with the car being dangerous on the road with defective brake related parts, and rendered inoperable. 

The brake pedal is hard. The car does not want to stop. The brake booster is not working. The car only has 40,000 miles

Engine loses power while driving. This happened the first time on 8/24/2. I was on the NJ Parkway in highspeed traffic . The vehicle would not drive over 25 miles an hour putting all occupants in the car at risk. The dealership repaired the vehicle The same loss of engine power re-occurred on 3/12/22 while driving at over 50 miles an hour. the car just slowed without warning, and I was unable to increase speed on a busy roadway

Why driving on the Interstate with some congestion I made an attempt to accelerate from behind a slow moving truck and in doing so my car slows down as if it stalls in the middle of road. Engine light and traction comes on. During this I cannot apply acceleration until my car is ready. Normally I’d have to pull over but if I’m in traffic I can not. This has been reported to The dealership starting at 900 Miles. I was told it’s probably bad gas. I continue to report and was advised nothing is wrong. I have noticed a change in applying acceleration. Its more a force to go. This has been going on since the purchase. I am now at 19, 273 miles

Engine Light came on before a full year of having the car. Started August 23 2021 the car will take forever to move like engine was lock up or something then when you put the car in drive it was go backwards and when you put it in reverse it will go forward. Car has a head of its own. I am pregnant I don’t feel safe In this car and this car is not safe for my baby to be in I spoke to different people who has the same car as me they experiencing the same thing 2019 and 2020 ..

Shift to park displays when I put my car in park and the vehicle will not turn off. I have read that there have been recalls on this issue up to 2019 but nothing for 2020. My car is not even 2 years old...I shouldn't have a problem turning my vehicle off especially since it's been an issue in the past

Speed reduced, reduced engine power , hard breaking and noise ,engine light one , all gages flash, service esc! On dash

The contact owns a 2020 Chevrolet Malibu. The contact stated that while driving at various speeds, the vehicle would intermittently hesitate and stall with the traction control and check engine warning lights illuminated. Once the vehicle stalled, the contact had to wait a few minutes before successfully restarting the vehicle. The vehicle had been taken to the dealer on multiple occasions however, the mechanic was unable to duplicate or determine the cause of the failure. The contact had the pistons, battery terminal, transmission, and wiring harness replaced; however, the failure persisted after each repair. The manufacturer was notified of the failure and referred her to the NHTSA for assistance. The vehicle had yet to be repaired. The failure mileage was unknown.

The vehicle will randomly shut off while driving. All warning lights light up on the dash and notification of "reduced steering" pops up. Taken to the dealership and has been there for 19 business days. They will fix a component, I have picked it up twice and it has shut off before I could even get home forcing me to tow it back. This last time they were bringing the car around and it shut off in their own parking lot before they could even give me the keys. Every time they run diagnostics it's a new code. Vehicle is unsafe to drive due to shut-off and loss of steering.

This is an intermittent issue and hard to reproduce on demand. I have evidence in the form of multiple videos that may be provided anytime. Videos can be found here: https://www.dropbox.com/sh/zubc5ilgahayvxa/AABf3M1mLBikxQswv17Yn-YQa?dl=0 In the middle of driving on freeways, highways, or regular roads, the car will quickly slow down to a very low speed, around 5 mph causing other drivers to have to quickly swerve out of the way before wrecking into me. The power steering will also intermittently fail, as it becomes difficult to turn the wheel during these times. The car will also not accelerate at my will like it should at this time. Check engine lights will show up, as well as other warning notifications on the dash board. Some of the warnings include "Service Power Steering. Drive with Care", "Fuel Level Low", and "Service ESC". The car will also intermittently show all gauges in the zero/off/empty position. The car will also say "Shift to Park" when trying to turn it on, even though it is already in shift. I have sent the car back to the dealer 5 times to date and am about to pick it up again today as they have called me and said "it's ready" again. Each time they take the car, they do not address the issue. The first time I took it in, they just performed a recall repair for the camera and suggested the problem may be fixed from that. They claim they cannot fix something they cannot reproduce but I suspect they do not want to spend the time/hours/money it will take to figure out the problem since it is still under factory bumper-to-bumper warranty. It is still under factory bumper-to-bumper warranty but Monument Chevrolet in Pasadena TX refuses to repair anything and claim there is no evidence of the problem even though I've emailed them multiple videos of the problems happening. Auto Nation in Houston TX is who has the car now. It was recommended to me by General Motors to try another dealer. This is where I'm at currently with the situation.

VEHICLE SEEMS TO WANT TO STALL OUT FROM TIME TO TIME WHEN PRESSING THE GAS

CAR LOST POWER WHEN PASSING A TRUCK ON THE HIGHWAY, HARD START,IMMEDIATELY CONTACTED DEALERSHIP. THEY HAVE HAD THE VEHICLE FOR GOING ON THREE WEEKS TOMORROW. THEY HAVEN'T BEEN ABLE TO DIAGNOSE THE PROBLEM. I HAVE CONTACTED GM AND THE SERVICE REPRESENTATIVE AT THE RESOLUTION CENTER SAID THE DEALERSHIP WAS NOT ANSWERING E-MAILS AND HE COULD NOT GIVE US ANY INFORMATION. THE SERVICE MANAGER AT THE DEALERSHIP SAID HE AND THE MASTER TECH HAD BOTH DRIVEN THE CAR AND BOTH SAID THAT THEY DETECTED A PROBLEM. THE SERVICE MANAGER SAID THE DIAGNOSTIC COMPUTER SHOWED EXCESS, OR UNBURNED FUEL IN THE #2 CYLINDER. THE MASTER TECH SAID HE PUT A BORE SCOPE INTO THE #2 CYLINDER AND SAW A BURNED OR DISCOLORED SPOT ON THE PISTON. THE SERVICE MANAGER SAID THAT A REGIONAL ENGINEER HAD COME DOWN FROM SPOKANE WA. AND DRIVEN THE CAR WITH ANOTHER DIAGNOSTIC COMPUTER. THEY STILL HAVE NOT DIAGNOSED THE PROBLEM, AND THE DEALER SAYS THAT GM WANTS US TO TAKE THE CAR BACK AND DRIVE IT. WE FEEL THE CAR IS UNSAFE AND WE ARE REFUSING TO DRIVE IT. THEY ARE NOT COMING UP WITH A RESOLUTION TO THIS SAFETY PROBLEM.

RAIN IN GETTING INTO THE TRUNK AREA BY A LARGE AMOUNT OF WATER. LEAVING THE SPARE TIRE SITE FULL OF WATER.

MY CAR HAD ONLY 600 MILES AND IS BRAND NEW. AFTER SITTING ON THE DRIVE OVERNIGHT THE CAR WOULDN'T START. THERE WAS A LOT OF CLICKING NOISES, BUT THE ENGINE WOULDN'T TURN. THAT WAS THREE WEEKS AGO. I BROUGHT IT TO THE DEALERSHIP AND THEY SAID THAT THERE WERE ERROR CODES ON THE BATTERY, AND THAT THEY RECHARGED IT. TODAY, THE CAR CLICKS AND WON'T TURN OVER AGAIN. THE CAR NOW HAS 1000 MILES. THE DEALERSHIP TOLD ME THAT CARS DRIVING BY THEIR LOT AT NIGHT WILL CAUSE RANDOM PARKED NEW VEHICLES WITH NO KEY IN IT TO FLASH LIGHTS, AND USE OTHER ELECTRICAL COMPONENTS RANDOMLY AND IT KILLS THE BATTERIES. I THINK THIS IS A MAJOR CONCERN. I PARK THE CAR REGULARLY IN PUBLIC LOTS AT THE AIRPORT. I CAN'T HAVE MY CAR BATTERY DEAD ALL THE TIME SIMPLY BECAUSE IT DECIDES TO TURN ON AS OTHER CARS DRIVE BY.

MY 2020 CHEV MALIBU, NEW 10/19, WAS PROMISED 29 MPG CITY BY CHEVROLET'S WEB SITE AND THE VEHICLE SALES STICKER. I AM ONLY GETTING AT THE VERY MOST 25 MPG AT THE VERY MOST. I LIVE IN SAN DIEGO AND DO DRIVE IN THE CITY FOR ALMOST ALL THE CURRENT 2,000 MILES. THIS IS THE PRIMARY REASON I BOUGHT THIS CAR! I TOOK IT TO THE DEALER ON 1/17/20 & THEY TOLD ME ALL WAS WORKING PER SPEC'S.

MY 2020 CHEV MALIBU PROMISED ON THE WEB SITE AND ON THE MSRP THAT IT WOULD GET "29 MILES PER GALLON IN THE CITY". THIS WAS ALSO PROMISED ON THE 2021 MODEL. I HAVE ONLY GOTTEN 24 MPH OR LESS IN THE CITY. THE CAR IS ONE YEAR OLD. I HAVE HAD THREE MEETINGS & SERVICE CHECK OUTS WITH THE DEALERSHIP AND THEY TELL ME THAT THAT THERE IS NOTHING THAT THEY CAN DO. SO, I NEED GOVERNMENT INTERVENTION TO FIX MY VEHICLE SO THAT IT GETS WHAT WAS PROMISED.
