2018 CHEVROLET MALIBU Complaints

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).

Keep getting a warning on my dashboard saying that the engines power is reduced.

The steering wheel is jerking when in the position to turn, and waiting at a light. The STOP ENGINE Feature seems to make the jerk motion and also sends an ALERT MESSAGE which is a quick flash STATING "Steering Assist is REDUCED- Drive with Care". According to a SERVICE BULLETIN Provided by GM BULLETIN #19-NA-182 AUGUST 2019. This is a problem that needs to be corrected, for the safety of my family and others in the vehicle and on the road. Technicians must replace or reprogram the POWER STEERING control module with the latest and most up to date one. I am aware there in no specific RECALLS but this issue is new and I do not feel SAFE and I would like it corrected.

Shift to park appears. Helpless in car cant shut off. Car has only 33,000 miles on it. I have read many with same problems across a variety of GM products. I consider it a danger and safety problem.

Car powered down while driving all the lights lite up on the dashboard. When driving it either speeds up on its own or while driving it will just go slower without me letting up off the gas.

While driving on the highway my car decelerated from 60 mph to 25 mph in an instant. This almost caused a major fatal crash. My check engine light is on saying engine power reduced.
