2015 Chevrolet Malibu electrical system problems

“Fuel sensors failing, codes obd are not fixing issue, auto stop, shuts radio off when brake is applied, resets all electric components in car. Every time braking at a stop or signal.”

“While driving my 2015 Chevrolet Malibu on a four-lane highway with a posted speed limit of 70 mph, the vehicle displayed an “Engine Power Is Reduced” message and limited the vehicle to less than approximately 25 mph. This created a serious safety concern because the vehicle could no longer maintain highway traffic speed, resulting in a significant speed differential of nearly 45 mph below the posted limit and surrounding traffic flow, creating a high risk of being struck by other vehicles. The vehicle also experienced an alternator problem while being driven on the highway. It repeatedly acted like it was not getting enough power to maintain the speed of surrounding traffic, and we had to pull over on the side of the road. The vehicle has also had an engine-related issue discovered during repairs. When the valve cover gaskets were replaced, the vacuum pump was found to be severely damaged, and metal shavings were found in the engine oil. The reduced-engine-power problem has occurred in connection with the vehicle's electrical and engine problems. The vehicle and affected components may be available for inspection upon request. The vehicle has been inspected…”

“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.”

“The transmission and engine fails repeatedly. The vehicle repeatedly stalls while accelerating at all speeds, simultaneously, the gear shift lights,dash lights, radio, etc restarts. Issue also happens when shifting gears. Issue happens at every stop light and stop sign, when the vehicle is engaged in ‘auto stop’. The vehicle has been in and out of the repair shop since 2022 for TCM/ECM failure. The vehicle has been inspected by Chevrolet twice and other repair shops. Problem persists and the vehicle is not safe to drive. The vehicle has to be jumped daily in order for it to work even after purchasing several batteries and alternators. Warranty company, SilverRock, denied claim. When shifting gears, the warning message states ‘power steering’ and all of the car lights disappear and the vehicle stalls. These issues appeared 31 days after purchase in May of 2022.”

“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.”

“My car has the auto shut off and when im driving it sometimes just dies while im driving with no warning and no power steering to pull over. Also when im at a red light and the auto shut off comes on when it starts back up all my head lights turning signals radio everything goes off and comes back on when the car restarts then when u go to take off it will die and everytime I push on the gas it hesitates to go if it dont die. I took my car to an independent car repair shop and they said they have tested everything and I have also replaced the front and back batteries and I was told it is the computer and he has had several of the same car come in with the exact problem.”
