2015 Chevrolet Malibu: check engine light

Filed Jan 21, 2026 · Electrical, Engine · MO

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.

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

P16cf dtc and check engine light after some engine noise and an incident where I was trying to accelerate around an obstacle but was unable to. The car bottomed out and would not accelerate until I took my foot off the gas and tried again more slowly. It's an issue with the intake solenoid rocker arm (oil control valve). The issue with this particular part was noted on earlier Malibu models but not mine. I have not taken it to the dealer yet as I am out of the power train warranty.

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.

I was pulling out of parking lot when my car gears started to jerk then a "service power steering" icon flashed on the dashboard. My engine light read a p305f code which only told me it was a problem with the dual battery control module (dbcm) I then took the vehicle back to my local dealership and there diagnostics just said to replace the main battery. However I replaced both batteries and car still had the same problem. I did my personal research and I ended up replacing the battery module yet car still had same issue. I've already been to the dealership twice and can't afford to keep spending money on diagnostic test. I also noticed that this was a common issue for this vehicle and that multiple people had filed complaints about this particular problem. This problem happens to me at random times while driving or while pulling out of parking lot and is a major hazard if driving on busy street or highway. When it does the auto stop at a red light the car jerks and sometimes gears will lock up and transmission will experience problems as well. Other times the car just jerks and a service power steering icon will display on the dashboard

I can be driving at normal speed and I receive an error that the engine power is reducing and the speed shifts down & I am unable to exceed 25 MPH. The check engine light pops on & also an error regarding stabil loc needs to be serviced. My car has automatically shut off in the middle of traffic. I've had to pull over to a safe medium on the highway and mostly when the error occurs, I'm not able to turn a corner at a safe speed. Although I am able to start it right back off the error still persists. I have had what "they say" is the issue repaired twice but as soon as I get the car back, I have the same issue 1-3 days later.

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.
