My -??18 Malibu LT has over 39K miles, and just tonight, i started my car, the engine light and traction control light both came on, followed by a message saying -??Engine Power Reduced-??. I then decided to drive for a little to see if i notice any problem. After driving for about 4 minutes, my car went from 37mph down to 20mph. It felt like the engine was forcing itself. So i then pulled over to the side of the curb, turn the car off, then back on. i noticed the warning engine light was still there but the traction light weren-??t there no more. So i drove back to my place, turned my engine off. Then i plugged my diagnostic device to see what code(s)were they, and 1 code came up and it was P2138. Which is Throttle/Pedal Position Sensor. Oh by the way, I also would like to mention one more thing which is the -??Shift to Park-?? message i started seeing whenever i park my car (putting the gear in park) and this first happened when my car was at 38K Miles (about a month ago).

2018 Chevrolet Malibu. Consumer writes in regards to issues with the engine. The consumer stated the accessories stay on when turning the engine off. The dashboard reads shift to park even though the gear is in park. The accessories then turn off after about 2 minutes. The consumer requested to have the vehicle repaired under warranty.

While driving 70 mph, I get an Alert that stated reducing speed. And my check engine light came on. This is not the first time. Lucky I was able to get off the Highway without getting into an accident. Also my car sometimes will not cut off because it says my car is in shift even though I have it in park. This is dangerous to have a car reduce speed while driving 70 mph to Abruptly go 40 mph. Last time this happen a month ago no codes came up and the check engine light eventually went off. But now my check engine light is back on again.

Engine lost power on interstate highway. While this did not result in a crash/ rear end collision, the potential for such injury seems high. 1-2 days prior there were some warning lights (check engine light). Called a dealership Tuesday morning and earliest service appointment was in one week but they assured me that the car was drivable in the meantime. On Wednesday afternoon my son was driving on the interstate and there was a new message -??engine power reduced-??, and a sudden loss of power. Eventually got the car to nearest Chevrolet dealership. Their technician took over a week to figure out what was wrong; eventually they replaced the ECM but still had problems. After a software update to ECM the problem finally appears to be resolved. Please note that similar problem has been reported with other Malibu models, but my Malibu Hybrid was not recalled. Please consider a recall of all GMmodels similar to the Malibu

Several times I have had the engine light come on and a warning of Engine Power Reduced. I have had it checked several times and some it was not able to be diagnosed but others the various modules were replaced - but the issue is not fixed. What is it going to take to have this brought to NHTSA attention as well as GM to get this corrected on a recall" I have almost been hit by 18 wheelers on the freeway due to my car dropping from 75 MPH to 30 MPH and there is nothing you can do when you are on a busy freeway in a construction zone but pray. I have read SEVERAL statements and reports of this happening over and over with other owners. I will definitely loan my car to an investigator at NHTSA or Mary Barra, President of GM, and let them see how safe they feel in a situation when this happens, especially when you have grandchildren or your own children in the car. It has been reoccurring since I purchased the car in 2018 with only 4 miles on the odometer so the information gathered below is only a fraction of the information that is needed. Maybe a selection on the "Was there a crash" and "Was there an injury or fatality"" should be "ALMOST, BU THANK GOD, NO"

The car doesn't start when I press the starter button. It clicks, turns off, and then factory resets all the dash electronics. It's been doing it ever since I got the car and even when at a stop while the car was on, the fuel saving systems will shut off my car at the light but it won't turn back on when I start to lift my foot off brakes.

- Rosemont, CA, USA

My car will not start. And it turn off at stop lights and when does the gas saving shut off, it doesn't turn back over. Im pretty sure it's the fuel injectors

There was an issue with the Engine and Transmission System. My Engine light came on and I received a warning that the Engine Power is Reduced and I had to pull over because the speed of the car reduced to 20 miles an hour. This happened a month again and then the car would not start. We bought a new battery and everything was fine until today were it happened again. I have to travel on the highway a lot and cannot have that happen again or I can be in trouble by causing an accident.

My engine power reduced signal on my 2018 Malibu lt comes on on my dash. I have almost been in a few accidents because of this on the highway. This is an issue that needs to be recalled asap. I have already gotten the entire gas pedal replaced. This is ridiculous because they already know about this problem but are too cheap to do a recall on it. Someone is going to die one day because of this and it will fall on the hands of the car company.
