    Vehicle won't start and dealership determine it was the battery. Replaced battery now vehicle shuts off completely when making a complete stop. Vehicle will maintain in normal operation if shifted into neutral upon stopping. The vehicle was taken to Harper Motor Dealership where it was determine the starter was bad. After replacing the starter the next the problem remained. Took the vehicle back the next day and after three days it was determined a GM expert was needed to determine the issue. One week later and a proposed bill of $3500 to repair I decided to write this down. This appears to be a major safety issue that could cause harm or death. This has been an issue since 2013 in the Malibu and the issue has still not been corrected.

    there is a issue with the chevy mailubu where a message will pop up on the dash and say engine power reduced which will significantly slow down the speed of the car and is impossible to keep up with traffic as someone who has to use the expressway everyday with a toddler in the car this is a big issue also im wondering why this isnt a recall on the the malibu because i know three other people with the same issue and we all have different year cars. chevy service team said the issue was from a pcv valve that will cause the exhaust to clog up.

    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.

    The harness and shifter solenoid went bad in my car. When I was on the highway, it stalled causing me to have to pull over onside the road. I nearly got hit in the rear by an 18-wheeler. There was an TSB on the make, model, and year of the car, but GM did not inform their customers of the issue and the dangerous situation one could be in if the car decided to malfunction in the middle of traffic. I was almost rear-ended from behind by an 18-wheeler while on the highway going 60 miles per hour. I also was stranded on the side of the road because they said they could not send anyone out. Malcolm Cunningham Chevrolet, a local Chevy dealer is aware of the issues with the vehicles, but when I bought my vehicle into the shop to get fixed, they lied and said I had wasted something in my car. They provided no pictures of the spills or pictures of the parts with the contamination that they claimed it had on it. The only person that inspected my car was Logan and the other technicians at Malcolm Cunningham Chevrolet in Augusta, Georgia. No, there was no warning lights indicating my harness and solenoid needed to be checked.

    While driving o Leo noticed temp gauge going up. Pulled into a parking area. All my antifreeze had drained through a hole in the lower radiator hose. It had worn through because it was against a pully.

    When the check engine light initially comes on, the car will go into "reduced engine power mode" which will decrease the power and speed of the car, forcing me to pull over and turn the car off and restart. This is a hazard to myself and other drivers especially when on the highway, driving at higher speeds. There has been an investigation in to GM where it was found that a few other models have this issue. This happens every time I have something repaired and the light comes back on, which has been twice in the past month. The first time this happened, I had the repair done and it was fine for a while. After the car has been off for a while and the light is still on when I start my car, for the most part the car is no longer in this mode, but it can come back on at any time.

    We have had this car since 2020 & frequently the "reduced engine power" warning comes on & the car will not/or very slowly accellortate. Along with the engine light on.We have hooked it up to a computer many times but nothing solves the issue. Lately it has been staying on constantly. Huge safety risk as my two children are in the car daily & we do take main roads/highways! When this comes on, the car will not remote start as well, also this is random in doing so, it has came on when I 1st start the car in the morning, while driving at 35mph, stopped at a light, or turn on any time I turn the car on. Doing some research and many others have had issues as well as their engines giving out at 60,000 milles (ours is at 57,000) & nothing resolved for them either. This is a huge safety issue and needs recalled. Us malibu owners should not have to pay to get this looked at constantly nor worry about owing on a car that could give out at any given time. We keep maintenance up on our car and this is the only constant issue we have that cannot be fixed.
