2015 Chevrolet Malibu Electrical System Problems

The car continues to die when I come to a stop. The error code for the engine light is P305F. I have changed both batteries along with several different sensors and spent thousands of dollars in repairs at a couple different shops and still can’t find the problem with this error code. I have fixed everything that this error code points to. The car will not pass inspection with the check engine code on. This should have been recalled as this is a very common problem.

I was coming home from school pickup, and the light said the engine power was reducing. Then the screen said that I couldn't go past 25 miles per hour. The skid sign came on also. The car started slowing down on its own. The car then stopped. I had to put on emergency lights quickly. I had my daughter and grandaughter in the car. Thank God we didn't get rear ended. I turned off the car and waited. I turned it back on and went home a half a mile away thankfully. I looked up for a recall and Google said that there was a potential for the same thing. The check engine light came on too. This has never happened the whole time that I've had it.

Wheel hubs causes car to think that it’s going faster(200mph) causing car to drop speed, locks steering wheel making it impossible to turn away from traffic and drive it’s an accident waiting to happen not sure why there isn’t a recall. Also batteries causes the battery system warning to be a major problem even if alternator is good. I’m not sure if the two batteries is a good idea. The stop/start feature can cause radio issues it’s like cutting the car off and turn it back on when brake is released radio comes back on.

have a 2015 Chevy Malibu that is randomly trying to start itself. The key fob is the original when I bought it. It has the auto start on the fob but is the kind that requires the key in the ignition to drive.car completely off (not in aux) but the key is in ignition, could be for 2 minutes or hours, and randomly it will try and start, but not fully turn the engine and actually start, just that little half second of a start and then go right back off. Today it did it 3 times in a row. Obviously I won’t be leaving my key in the ignition any longer as it does seem to require that,

The contact owns a 2015 Chevrolet Malibu. The contact stated while the key was in the ignition switch in the off position, the vehicle attempted to start independently. There was no warning light illuminated. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 150,000.

There is an electrical issue with the vehicle, causing bad computer readings related to the O2 sensor, VVT valve/rocker arm solenoid. It causes shaking and bad acceleration. These parts were already replaced and within days of the “repair”, I am still having issues. If driving and I start to accelerate, it gets shaky and almost stalls the vehicle completely. If that were to happen while driving in the middle of the road then that could easily cause a wreck.

I bought my 2015 Chevy Malibu in 2016 at 36k miles. No wrecks, 1 owner before myself. No warning lights on when driving from the lot and the car was just what I wanted… tho always a little doubtful because it was pre owned 1) there was always this random, unusual, indescribable smell from the vents where I couldn’t breathe but no one else could smell or experience it. I just kept getting sick. 2) I thought “MY” first 30k miles or so was rolling too fast and 3-5 months in, the ENGINE light popped on. Immediately took it to Chevy who said my engine light was on due to an “airbag” but wouldn’t tell me which unless I paid 70$. 3) Still, driving was not affected so I kept taking it to the Chevy dealer every 3-6 months for the proper maintenance. About 2 years in I go for an oil change at CHEVY: one guy pours RADIATOR fluid in my OIL compartment during the oil change. Just before he realizes it’s the wrong thing and looks to see if I saw, I alert the manager who immediately drains the oil and says it won’t be affected.. and assures me everything is fine. ??? 4) 4 years ownership, the service stability track message started appearing and the ENGINE POWER REDUCED SPEED LIMITED TO 25 MPH starts popping up on the screen and simultaneously the car DANGEROUSLY goes from highway speed to 25mph. ONLY Jesus mercy! That’s a death trap in itself. Still no recalls and no help. Temp fix (get to safety, turn off vehicle, wait 30 sec-1 min and restart) 5) At 150k miles, I returned to get transmission flush.change.check whatever the best procedure was. Chevy says, I wouldn’t because it doesn’t have to be serviced on these vehicle. yet they send me coupons for trans services. 6)JUST put on new tires, oil, oil cabin, and engine filters changed. Car riding smoothly then 4 days later I start it and up pops a message about SERVICE POWER STEERING: drive with care! No Gearshift lights. And it’s an EPS system! Something is WRONG with these cars. 7) Paint defects along pass. side

I have a 2015 Chevrolet Malibu. I was driving in traffic and stopped. The auto stop engaged. When I put my foot on the gas peddle to continue on in traffic, the engine would not start. I had to set there for 5 minutes before the car would restart.

During the automatic start/stop function, the car stalls out after it stops itself. For example, I exited an interstate and came to a red stoplight. The car engaged the fuel saving system and shut down the engine. However, after I tried to press the gas to get the car to reengage, the car completely shut down requiring me to put the car in park on an exit ramp and re crank the car to get it to start again. Batteries were tested and no one can figure out what the problem is.

The trunk will not open and if you force it open it will not close back. This has happened several times now and I’m not able to get into my trunk.

The mechanic then diagnosed that the fuse block was faulty. The fuse block was replaced and the failure was remedied. The manufacturer and local dealer were not notified of the failure. The failure mileage was 127,000.

This 2015 Chevy Malibu has been serviced over 10 ten times for a stalling/check engine issue(s). Sometimes the check engine light will activate after stalling and other times it will not. This vehicle has only had 1 owner since the initial purchase with on-star showing all the times/dates that a problem was detected and reported via email (on star). The dealership has had ample attempts to fix the issues with the vehicle, as well as private ASE certified mechanic/shop after the issues continued with this problem vehicle. This vehicle is a lemon, it is not dependable, and the stalling issues seem to be an on-going issue with GM Chevy Malibu. On 05/15/2021 while in Natick Massachusetts, I was almost rear-ended after my vehicle stalled in traffic and I could not get to the BDL. As quickly as the vehicle stopped working, I was able to restart the vehicle and move it out of the road. This problem can not be ignored or downplayed, someone will eventual get hurt or killed because their vehicle stalls without reason or warning. I need a dependable vehicle and do not have the luxury to run to the dealership multiple times for an on-going problem.

THE CHECK ENGINE LIGHT CAME ON. THE CODE IS P305F WHICH MEANS THE BATTERY CONTROL MODULE IS AFFECTED. THIS POWERS THE ACCESSORIES. WHEN THE AUTO STOP FEATURE TRIGGERS, THE VEHICLE'S ACCESSORIES WILL TURN OFF AND HEADLIGHTS WILL TURN OFF. DANGEROUS AT NIGHT. THERE ARE NO CURRENT SOLUTIONS FOR THIS CODE AND MAKES THE CAR A FAILURE FOR EMISSIONS.

THE VEHICLE WAS IN MOTION ON A CITY STREET AND THE WHOLE RADIO CONSOLE CUT OFF FOR ABOUT 5 SECONDS AND CAME BACK ON. THE ENGINE LIGHT THEN POPPED ON.IT DID THIS TWICE IN A MATTER OF 10 MINS. THIS ISSUED HAS HAPPENED TWICE SPORADICALLY 3 TIMES BUT NEVER CONSECUTIVE ON THE SAME DAY. BOTH BATTERIES WERE TESTED AND THEY ARE GOOD. GOT THE CODE P305F. PERFORMED A CHECK ON ALL WIRES AND HARNESSES AND THEY WERE SECURE. THE MAIN BATTERY WAS REPLACED WITH A NEW AC DELCO ON FEBRUARY 22, 2020. MY CAR ALSO CUT OFF ON SEPTEMBER 30 WHILE IT WAS IN MOTION AND I WAS SWITICHING GEARS TO REVERSE.

I WAS AT A RED LIGHT ON A MAJOR HIGHWAY NO WARNING WHAT SO EVER. LIGHT TURNED GREEN TOOK FOOT OFF BRAKE CHECK ENGINE LIGHT CAME ON THEN CAR COMPLETELY SHUT OFF. HAD POWER BUT I GUESS NOT ENOUGH TO TURN ON THE HAZARD LIGHTS. ALMOST GOT HIT IN THE REAR BECAUSE THEY THOUGHT I WAS GETTING READY TO MOVE BECAUSE THERE WHERE NO LIGHTS ON IN THE REAR. HAD TO PUSH IT OFF TO THE SIDE OF THE ROAD THAT WAS HARD DUE TO THERE WAS NO POWER STEERING AT ALL. GOT MY SON TO COME GET ME BUT FIRST WE WANTED TO SEE IF THE CAR WOULD START WITH A JUMP START AND IT DID BUT CALLED FOR A TOW TRUCK BECAUSE I WAS SCARED IT WAS GOING TO SHUT OFF AGAIN. THERE WAS NO WARNING OR EVEN WARNING SIGNS PRIOR TO THE INCIDENT. BESIDE THE CHECK ENGINE LIGHT COMING ON RIGHT BEFORE THE CAR SHUT OFF THAT WAS NOT A VERY GOOD WARNING. SO I BOUGHT A BATTERY FOR THE CAR AND EVERYTHING HAS BEEN FINE. I REALLY THINK THAT PUT ME IN A DANGEROUS SITUATION NOT BEING ABLE TO PUT MY HAZARD LIGHTS ON BEING ON A MAJOR HIGHWAY AND TRYING TO PUSH IT TO THE SIDE WITH NO POWER STEERING.

THE CAR STALLS OUT WHILE IN TRAFFIC AND/OR IMMEDIATELY REDUCE SPEED FLASHING-ENGINE REDUCE CODE ON THE DASH, MINES IN PARTICULAR HAS FLASHED SERVICE TRACTION AND REDUCE ENGINE POWER ON THE DASH, DIAGNOSTIC TESTING IS NOT GIVING ANY CODES FOR A SPECIFIC REASON FOR THIS ISSUE, SEEM TO BE SOMETHING UP WITH THE SENSORS AND ELECTRICAL SYSTEM ON THIS CAR- CAUSING MULTIPLE ISSUES TO HAPPEN ALL AT ONE TIME. CHEVY DEALER NOT VERY HELP- SUGGESTING TO FIX RANDOM PARTS AND THE ISSUE CONTINUES. DECIDED NOT TO DRIVE ON THE HIGHWAY, BUT DID DRIVE ON A BUSY STREET IN BALTIMORE COUNTY.

RUNS RUFF AND DIES AT STOPS (RED LIGHTS) IT'S HAPPENED 6 TIMES. *TR
