NHTSA Complaint #11445198 — 2017 CHEVROLET MALIBU

Driving on highway at about 65 mph on family trip to Delaware. . Car suddenly gave reduced acceleration error and speed started declining while in traffic. No warning.checked chevron app on phone and it did not see anything wrong. There was NO check engine or anything. Got to a dealer and they said it was probably a sensor for gas pedal. 5 days later driving home to Georgia from trip on highway around same rate of speed. No warning . The check engine light and reduced engine power warning message came on. This time the Chevrolet app notified me of trouble and said I needed the car seen within a day. .Got to a dealer and now they say they think it may be the cam shaft based on the code but they cannot replicate issue. I took a photo of the alert from the second incident . Car has about 46,000 miles and is well maintained . Our safety was at risk both times but especially the first time as we were in traffic and speed declined .
