NHTSA Complaint #11474815 — 2018 CHEVROLET MALIBU

On 3 occasions, my vehicle has displayed the message “Engine Power is Reduced.” It has 83, 990 miles. I took it to the dealership to have them check it out, but I was told they couldn’t check it because the check engine light was no longer on. This is a problem because the warning will come on, then the check engine light turns off after the car has been turn off. The Chevy dealership says there is a three day wait for them to conduct a diagnostic, but what are the chances the check engine light will remain on? After having gone through this process on three separate occasions, the check engine light hasn’t appeared the next day. I have read about how others may be experiencing this problem and they do not have some resolution to this kind of problem. My wife generally drives this car, so I fear for her as she travels to and from work.
