Go down the highway at speed limit then lose power with check engine and reduction of power lights come one. We can shut off the engine and wait a few minutes. Then turn the car back on with no problems for undeterred time frame before it does it again.

While driving on the expressway my check engine light came on with the message reduced engine power. The car slowed from 60 miles to 20 miles instantly, I panicked but was able to exit without harm. Once on the street the car would not exceed 20 mph. Almost like the transmission was pulling. I received an email from on star diagnostic stating critical issue with engine and transmission service immediately. I got to the dealer at the earliest allowed and the customer service tech told me the code showing was for the trottel and not the engine or transmission, but they would have to do a complete check. One hour later the customer service tech called for me and gave me my keys saying there is no known fix at this time for my problem and they reset the codes. If it happens again give them a call. At the time of the incident I was driving 60 mph and the mileage on my car was about 39,980.

While I was pulling into a parking spot, my 2016 Chevrolet Malibu suddenly accelerated without any warning. This sudden unintended acceleration caused my vehicle to jump the curb and strike a tree, which caused extensive damage to the passenger side fender, front grill etc.

The vehicle was taken to a dealer where it was diagnosed with a undetermined failure, but the vehicle was rewired. The failure recurred. The vehicle was taken back to the dealer and the accelerator pedal was replaced. The issue occurred several times with different repairs, but with an undetermined diagnosis. The manufacturer was notified of the failures. The failure mileage was approximately 3,200.

While merging onto a highway, the vehicle lost engine power and the "check engine" light came on. The information panel then displayed two warnings, including "engine power is reduced" and would not let the vehicle accelerate more than 40 mph. The information panel also stated "service driver assist system." The dealer states it's an issue with a faulty accelerator pedal terminal? however, this issue has happened three times over the past few months and is very dangerous when traveling on the roads, and power/acceleration is reduced and capped at 40 mph.
