2018 CHEVROLET MALIBU Fuelpropulsion System Problems

The vehicle shut off in the middle of the street. I had to get it jumped to start again. There was a fuel leak. Car is still smelling like fuel after getting it repaired. The vehicle doesn't alert if your close to a car or anything

After diagnostic troubleshooting from DTCs on a check engine light, it was discovered that the brake vacuum pump connected to the engine was completely nonfunctional. Previous symptoms included stiff brake, loss of brake power at random brake periods which could have cause and accident with other drivers, and finally malfunctioning sensors attributed to the exhaust system. This also led the vehicle to be unable to pass state regulated Emissions testing because of the inability to maintain proper emissions levels. Brake Vacuum pump that was removed from vehicle to inspect and diagnose is still available for inspection. Recent findings show that Chevrolet/GM is aware of the issue in their vehicles but refuses to address or replace faulty brake vacuum pumps. It is a common problem amongst 2013-2022 Chevrolet Malibus. Vehicle that is in question was inspected by a certified mechanic shop with failed emissions test. Solid check engine light appeared once...

Every so often I get an indication of engine power reduced, but every time I go in to get it checked it's off. I have recently just learned through research online that the issue is caused by a certain condition that gives false reading to the electronics. I have contacted GM and GM financial about the recalls on my cars of the same year. I have not been in a wreck but I have had the issue of engine reduced power in the middle of traffic. Cox Chevrolet in Bradenton has turn me away about the issue GM financial is giving me the runaround neither one mention anything about a recall instead I get a estimate $400 /$808.50/1900.41 all to fix ECM as I told the mechanic I was driving with no problem through the day me and the kids at the park when it was time to leave the...

Purchased a car for financing from Barret Motors and 2300 Lakeview PKWY, Rowlett, TX and as soon as I drove it off the lot on [XXX] the engine light popped on. I immediately called and was told to just take it to Chevy/GMC for servicing but was not told why, but just because the engine light was on I was told to go. I couldn’t take an appointment asap because I just started a new job which they also knew. The car has had a recall since 09-06-19 for an engine control module. Which is a serious issue and this car never had it completed and sold me a car with possible engine issue and did not inform there’s a recall on the vehicle for almost 5 years now. I took the car to get serviced at Chevy for the recall on 09/09/2025 and now I am facing multiple issues...

I have searched the prior recalls and I’m having the same problem that were said to be fixed. I would like the car check again for the recalls that said to be fixed and checked for all reacalls . The car turns of unexpected without warning . At random times the low power mode is always on and when I push down in the pedal it doesn’t respond well at all . I have invested countless money into fixing issues with this car .

On [XXX] while driving at highway speed on [XXX] in Columbia SC vehicle lost power and shut down. Was able to move to emergency lane. Car would not start.

I was going about 75 mph on the express way with one lane open due to construction. My car started losing power.I heard the chime and upon the dashboard were the words power reduced. My car slowed down in a matter of seconds to around 45 mph. A 18 wheeler was trailing behind me. I quickly jumped in the emergency lane to my right and took the next exit while riding the emergency lane. I shut the car off at the gas station, sat there for about 10 minutes, restarting my car helped temporarily. I was 3 hours away from home and had to drive back unknowingly if I will make it or not. I reached out to Chevrolet and was told to bring it in and leave it but they had no loaner cars for anyone at that time. I have replaced 2 sensors and now my start /stop...

Car has "check engine light" mechanic says vapor canister vent solenoid is bad. Part number: 2282618. Also said they have been seeing this a lot on Chevy Malibus and other GM cars. Part was not available from Chevorlet for oven two months.

Started car after acceleration, car started shaking , check engine light came on , acceleration decreased and message saying service Stabilitrak. 6 hours later started car and message no longer, check engine light off and car not shaking anymore. Chevy dealership diagnosed misfire, fuel injector needs replaced and damaged ECM.

When parking it says shift to park even when I’m already in park. The dealer says it’s the shifter however after seeing numerous other vehicles with this issue I believe it’s electrical

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!

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...

My car does not register when it is park. I cannot disable the car when this happens. I have been that my car is not in the recall that has already been issued for this issue.

Underlying fuel pump went out

Brake Power Booster, vehicle not starting. Not catching, brakes when completely out couldn’t stop

MOTOR DIED GOING DOWN THE ROAD Car is available for inspection If I had been crossing the street without the aid of a stoplight, I would have been T-Boned Vehicle problem has not been reproduced or confirmed by the dealer. Vehicle component has not been inspected by dealer or anyone else. The check engine light and logo came on as the engine was shutting down. I went into the trunk on the passenger side and shook and twisted the wires going into the control module mounted to the trunk wall. This was suggested for the 2016 Malibu which had a recall. There should be a recall on the 2018 also. After repeated shaking and attempting to start the motor, it finally started. I drove it home and parked it. When I went to read the code, the engine started and ran for a couple of minutes and stalled again. The...

My car just stopped in the middle of the road , and would not start again for a few minutes. Then is was in low power mode , no brakes either after that , found that problem to be a bad Vaccum pump , which G M didn’t even have , and a faulty Accelerator Pedal sensor !

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.

My car constantly gives an error saying the power is being reduced to the engine. It was repair 3 months after I bought it but it didn't fix the issue. These cars a danger to everyone around us. They reduce speeds to very low numbers even on the freeway, when yielding to turn left the car won't go but will drift into oncoming traffic, and many times the car won't shut off. It says it's not in park but it is. The seatbelts look like they're secured but with one good tug they'll come apart. And I slide when braking even without snow or rain. Mine I'd always broke down and no one will help me. I pay 475 a month for a car that doesn't work and is dangerous to me and my special needs child and everyone around us. Please do something.

I was driving 35 mph when the message "reduced engine power" and it noticably slowed down. The check engine light is still on. I researched recalls/problems with the 2018 Chevy Malibu and this is one major one I found.

Son was driving my 2018 Malibu with 90,000 miles. Check engine light came on and car reduced speed from 75mph to 40mph on interstate! Autozone reading says replace Variable Camshaft Timing Solenoid. Very dangerous situation. Chevy should have to fix this.

Warning: Reduced speed, car stalled in the middle of traffic. Took to dealer ship and they charged me $279 and said it was the battery, from the looks of everyone else’s complaint, which we have the same complaint, I got ripped off. I deserve a refund and we all deserve our cars serviced.

Certain @018 Chevy malibu models has a recall for asoftware problem could disable the fuel injectors And im currently having this issue where my vehicle will not start all of the time and is misfiring.

The car is going slow when you put it on drive a jumps then when you press on the gas it goes real slow then it kicks in at a faster level but when am at like 30 mlp it Jenks as if it wants to lock on me

Reduced engine power occurs while driving and will indicate a traction control issue and the check engine light will engage. The first time it happened, it was during a snowstorm on 2/24/2022, but it has occurred two other times while driving on a highway on sunny days (3/3/2022 and 3/8/2022) with no snow on the ground, road completely dry. Car speed dropped from approximately 55-60 mph to 20. I have to pull the car off the road, turn it off, and let set for at least one minute turned off before it will have engine power restored. Code for car was checked, and it was P2138, throttle/pedal position sensor switch.

engine shuts off with out warning. shuts completely off sitting a stop light and has to be put in park and restarted. shuts of in drive through and scared it will begin doing while traveling down the highway. no warning lights or nothing on. was told at dealer if not doing all the time or there was no light on indicating a failure that there was nothing could be done. very dangerous problem

My 2018 Chevy Malibu has been working fine then all of a sudden the warning light came on and the message warning light read ENGINE POWER REDUCED While I was driving on the freeway at 60 mph dropping my speed to 25mph instincts told me to pull over, so I did! Then I tried to drive again still no power it was like a strong pullback! So I again pulled over and turned my car engine off! Let it sit a few hours before driving up to local automotive parts store to use the ODII code reader and it read the code P2138 Throttle/ Pedal Position Sensor Correlation The part to order is $120.00 I am not able to get it today so I googythe problem and found out that this is a possible RECALL ??!!??

Vehicle jerks when accelerating. Loses power. Usually will stop after turning the car off for a few minutes. Different engine codes have came up (camshaft position timer, air intake system) no one can seem to find the problem

While driving engine warning function low power. Would not accelerate above 20mph. Defective accelerator pedal assembly and sensor.

Driving on I20 in heavy traffic all doing 75MPH the car lost all power.Although I had plenty of gas it did no good pumping the gas pedal .Fortunatly I was in the left lane and coasted to the shoulder before anyone collided with me. If I was in the right lane I am sure a collision would have occured as traffic would not have allowed me to get to the shoulder.After several hours I got towed 70 miles to the dealership.There was absolutely no warning of a problem prior to the incident. According to the dealership the fuel pump sensor shorted out and no gas could get to the engine.The car is still at the dealers as they have not gotten the backlogged part to repair the vehicle

Fuel injectors went out on my car I had no power to drive

Reduced power mode came on and the fuel injectors arnt going to the emc

Vehicle slows way down and loss of power. Engine power reduced. On heads up display. Seems to use alot of gas when this happens. I need to pull over and shut off car. Wait a bit and then restart. And get back on road. It did this 3 times in my commute to work. Also was snowing that morning and was slippery out so very dangerous almost was involved in an accident but luckily not. Seems to do this more in the colder Temps. It has happened however in summer also but not as often. I have read many complaints about this issue. I am not sure why GM has not figured this issue out yet. Very concerned.

Car suddenly stops and takes several minutes to turn back on. During the time the car is off there is no electrical power. After a few minutes (5-10) electrical power returns and car is able to be started. This has happened everywhere from our driveway to a highway ramp and happens without warning.

Car powered down while driving all the lights lite up on the dashboard. When driving it either speeds up on its own or while driving it will just go slower without me letting up off the gas.

Water leaking from under the glove box. Has passenger front and back floor soaked. Foul smell Car losing power in fuel injector. Stalling while driving.p0317 and other codes. Has been inspected by Gateway Buick in past, they charged me 200 dollars and the nhtsa issue said they would not. The vehicle is not running and will not crank.

I just went and picked up my car after having the recall cone.. Vin#[XXX].The car stalled on me when trying to trying to accelerate I almost got hit because of this...This has happen way to many times. This repair was supposedly done on 07/07/2021. Also this car had the same issue and a recall was done back in 2019. This car is totally not safe. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

I BROUGHT MY CAR BACK IN JUNE . I'VE BEEN HAVING PROBLEMS AND THINKING IT'S ONLY MY BATTERY BACK TO BACK . I'VE BEEN STOPPED IN THE MIDDLE OF THE STREET WHERE MY CAR WOULD JUST COME OFF . ONE TIME JSO POLICE HAD TO GIVE MY CAR A JUMP IN THE MIDDLE OF THE STREET AT A LEFT TURNING LIGHT. MY CAR HAVE STOPPED ON BEACH BLVD WHICH WAS EARLY IN THE DAY IN THE MIDDLE OF THE STREET . IT GOT TO THE POINT WHERE I HAD TO GET A PORTABLE JUMP STARTER. I LOOKED INTO IT & GOT BRAND NEW PARTS FOR SO MANY THINGS AND ONE DAY IT JUST WOULDN'T CRANK ANYMORE . THE LIGHTS AND RADIO AND EVERYTHING COME ON AND EVERYTHING BUT IT'S NOT CRANKING ANYMORE . I CALLED MANY CHEVROLETS AND WAS INFORMED BY THAT MANY 2018 CHEVROLET MALIBU'S WERE RECALLED AND NO...

THE CAR US UNDER 60,000 MILES THREE YEARS OLD AND ALREADY BREAKING DOWN. THE AIR FLOW SENSOR OUT OF SELF-TEST RANGE, TURBOCHARGE ENGINE UNDERBOOST PROBLEMS AND MASS AIR FLOW SENSOR PERFORMANCE IS ALSO PROBLEMATIC, MAKING THE CAR STOP INSTANTLY AND SPORADICALLY CREATING A HIGH IMMINENT DANGER OF CRASHING AND SERIOUS INJURIES. LUCKILY THE CAR BEHIND ME WAS FAR ENOUGH TO STOP BEFORE REAR-ENDING ME. HAD IT BEEN A SEMI-TRUCK I DON'T THINK I WOULD HAVE BEEN SO LUCKY. THESE ISSUES NEED TO BE IMMEDIATELY RECALLED AND CORRECTED!!!

WHEN THE LEFT TURNING SIGNAL IS ON AND FOOT ON BRAKES THE VEHICLE CUTS OFF ALL LIGHTS ON DASHBOARD LIGHT UP AND WHEN YOU PUT THE VEHICLE IN PARK AND TRY TO RECRANK A MESSAGE STATED NO GASOLINE.

WHILE DRIVING ENGINE POWER REDUCED MESSAGE COMES ON AND SPEED IS CUT TO BELOW 35 MPH.

WHILE DRIVING THE CAR WILL SLOW DOWN AND SAY SLOW ENGINE POWER

WHILE DRIVING MY ENGINE AND TRACTION LIGHT CAME ON AND A SENSOR POPPED UP THAT READ 'ENGINE POWER IS REDUCED'. I WAS DRIVING DOWN THE HIGHWAY AND MY SPEED WAS REDUCED. I CAN'T AND COULD NOT SPEED UP.

MY 2018 MALIBU HAS A FEATURE THAT WHEN THE CAR STOPS THE ENGINE WILL SHUT DOWN WHEN YOU APPLY THE BRAKES AND ENGINE WILL START BACK WHEN YOU RELEASE THE BRAKE MY CAR HAS SHUT COMPLETELY DOWN WHEN I'VE COME TO A STOP ALL POWER SHUTS DOWN THE HEAT THE RADIO EVERYTHING

MY CAR HAS A LITTLE OVER 62,000 MILES AT ABOUT 28,000 MILES THE WARNING WAS COMING ON REDUCED SPEED I'D BE ON THE ROAD AND THE CAR WOULD START SLOWING DOWN AND EVEN SOMETIMES ON THE INTERSTATE AND RECENTLY STARTED COMING ON AGAIN I COULD FEEL A POPPING LIKE IN THE GAS PEDAL. THEN THE OTHER DAY I WAS SITTING IN A PARKING LOT AND THE SHIFT TO PARK MESSAGE CAME ON WHEN I WENT TO PULL OFF IT JUST JUMPED. THERE WAS NO WAY TO PUT THE CAR IN NEUTRAL TO BACK IT UP I WASN'T EVEN ABLE TO TURN THE CAR OFF. I HAD TO LEAVE MY CAR RUNNING IN THE PARKING LOT FOR HOURS UNTIL IT DIED. THEN BEFORE THIS THE CAR MOVED SO SLOW IT HARDLY TOOK OFF. OTHER CARS HAVE TO GO AROUND ME. I HAVE HAD THIS CAR FOR TWO YEARS AND JUST SEEMS...

WHEN I'M SITTING AT A STOP LIGHT AWAITING MY TURN TO PROCEED WITH MY FOOT ON THE BREAK THE CAR IS FINE. AFTER SITTING AT THE LIGHT AND IT'S TIME TO DRIVE, I REMOVE MY FOOT FROM THE BREAK AND MY CAR SHUTS COMPLETELY OFF. WHEN I APPLY A LITTLE GAS THE CAR TURNS BACK ON AND IT MALFUNCTIONS EVEN MORE. MY DASH BOARD GOES HAYWIRE WITH DIFFERENT ERROR MESSAGES. IT SAYS THE FUEL IS LOW WHICH IT IS NOT, I COULD HAVE A FULL TANK. THE BACK DOOR IS UNLOCKED, I'VE NEVER SEEN THAT MESSAGE BEFORE UNTIL THE MALFUNCTION. MY BLINKER TONE EVEN CHANGES AND MY CAR IS RELUCTANT TO ACCELERATE. THIS HAS OCCURRED TWICE NOW.

TWO TIMES MY VEHICLE HAS DISPLAYED ENGINE POWER IS REDUCED WHILE DRIVING ON THE HIGHWAY. WHEN THIS OCCURRED, MY VEHICLE WOULD NOT ACCELERATE WELL AND MY VEHICLE SPEED WAS AUTOMATICALLY REDUCE TO ABOUT 20 MPH ALMOST CAUSING A CRASH WITH THE VEHICLE BEHIND ME. THE ENGINE LIGHT STAYED ON THE ENTIRE DAY EVEN AFTER POWERING DOWN MY VEHICLE. ALSO THERE IS A LOUD WATER NOISE WHEN COMING TO A STOP LIKE WATER IS RUNNING THROUGH THE ENGINE OR TRANSMISSION SYSTEM. THIS WATER NOISE OCCURRED WITH MY 2013 MALIBU AS WELL AND SHOULD BE INVESTIGATED.MY VEHICLE IS ONLY 2 YEARS OLD AND SHOULD NOT BE EXPERIENCING THESE TYPES OF ISSUES.

IN MAY OF 2020 I TOOK MY VEHICLE TO A CHEVROLET DEALERSHIP IN WOODBRIDGE,VA FOR A ECM RECALL ON MY VEHICLE. AFTER WAITING FOR THEM TO DO THE RECALL THEY STATED NOTHING WAS WRONG WITH MY VEHICLE. FROM OCTOBER TO CURRENT MY VEHICLE HAS BEEN DOING EVERYTHING THAT WAS STATED IN THE RECALL WHICH LEAD ME TO BELIEVE THAT THEY NEVER CHANGED THE PART. MY VEHICLE HAS SHUT OFF ON ME IN THE MIDDLE OF THE ROAD ALMOST CAUSING ME A ACCIDENT AND MOST DAYS NOW IT WON'T EVEN START. I GOT MY BATTERY CHECKED OUT AND MY BATTERY TESTED 100% SO I KNOW THAT WASN'T THE PROBLEM. I CALLED THE DEALERSHIP AND THEY SAID I WOULD HAVE TO PAY TO GET THAT PART REPLACED. WHY SHOULD I HAVE TO PAY WHEN IT'S ONLY BEEN A COUPLE OF MONTHS SINCE THE RECALL, SOMETHING ISN'T RIGHT. PLEASE ADDRESS THIS ISSUE. -THANK...

WHEN DRIVING THE CAR IT WILL LOSE PROPULSION AND POWER. AT ONE POINT IT ALMOST SHUT OFF WHILE DRIVING ON THE HIGHWAY. I TOOK THE CAR FOR INSPECTION TO CHEVROLET DEALER BUT I WAS TOLD THEY WILL TAKE WEEKS TO FIND THE EXACT ISSUE. IT ALSO HAS A SAFETY RECALL WHICH WASN'T PERFORMED DURING MY APPOINTMENT. I WAS TOLD TO COME BACK IF I SEE ENGINE LIGHT WITHOUT IT THEY CAN'T DO MUCH. I USE MY CAR EVERY DAY TO GET TO WORK AND NOW I FEEL UNSAFE WHILE DRIVING IT. MY CHEVROLET MALIBU IS OF THE YEAR 2018 WITH ONLY 30K MILES.

THIS IS THE 3RD TIME FOR HE SAME ISSUE. AFTER A COLD START THE ENGINE WILL START MISSING ON A CYL WHICH RESULTS IN A HUGE DECREASE IN POWER AND RUNNING ROUGH. THIS LAST TIME, ENGINE LIGHT CAME ON. JUST LIKE THE OTHER TIMES, IF YOU STOP AND RESTART THE CAR, THE ISSUE GOES WAY. TOOK TO DEALERSHIP AND EVEN THOUGH THE ENGINE LIGHT CAME ON, NO CODES AND THEY COULDNT REPLICATE THE ISSUE AND NOTHING WAS DONE.
