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 .

I was going 70mph on the highway, when I got a sudden alarm from the car saying "reduced power". The car would not accelerate and started slowing rapidly, almost resulting in a collision. The car would not go more than 20mph. I had to pull off to the shoulder, restart the car several times, and then was able to get the power to come back, but the check engine light remained on.

While driving received recurring check engine light for p2127/p2138 code. Has been to Quirk Chevrolet twice previously for same issue, drives fine for a week or two and light comes back. Third service appointment scheduled for Monday 6/7/21. Recurring issue has made vehicle unusable while effected as car goes into limp mode while in motion limiting speeds to 25mph which was interesting to say the least as it happens while in motion.

OBD2 codes ran on vehicle show: P0138 ("O2 sensor circuit High voltage bank 1 sensor 2") P013E (unknown) P2138 ("Throttle/Pedal Position Sensor Switch D/E Voltage Correlation") Vehicle is getting poor fuel mileage and has a drastic delay in acceleration after pressing the gas pedal, putting driver in immediate danger in traffic.

WHILE DRIVING ON MULTIPLE ACCUSATIONS MY ENGINE LIGHT WOULD COME ON AND GO OFF WITHIN MINUTES AND NOT RETURN TILL I TURN THE CAR BACK ON OR WHILE DRIVING LATER ON IN THE DAY OR DAYS AFTER SEEING THE LIGHT COME SO I WAS UNABLE TO BRING IT IN TO GET CHECKED OUT PROPERLY. A MONTH PASSED WHEN THE ISSUE APPEARED AND WHEN I DECIDED TO GO INTO THE DEALERSHIP TO POSSIBLY TRADE IN MY CAR THE LIGHT WAS NOT APPEARING FOR DAYS BEFOREHAND AND THINGS WERE NORMAL TILL A A COUPLE DAYS AFTER I LEFT THE DEALERSHIP MY CAR READ ON THE DASH 'REDUCED ENGINE POWER ' I WASN'T ABLE TO ACCELERATE QUICK ENOUGH IN THE MIDDLE OF TRAFFIC ON MILITARY TRAIL AND BELVEDERE I HAD TO PULL THROUGH A WALMART PARKING LOT TO AVOID ON COMING TRAFFIC AND BRING THE CAR TO MY HOME CLOSE BY VERY SLOW AND SLUGGISH DUE TO NOT GETTING ANY ACCELERATION FROM ME PRESSING ON THE PEDAL. THE DEALERSHIP WANTS TO REPLACE MY FUEL PUMP SYSTEM AT A COST HOWEVER IT HAS A CURRENT RECALL FOR MY SPECIFIC MAKE AND MODEL.

I PURCHASED THE VEHICLE IN 2018 WITH 20,000 MILES ON IT. MY CHECK ENGINE LIGHT HAS BEEN ON MORE THAN 7 TIMES IN THE PAST 2 YEARS. I HAD TO HAVE THE FUEL INJECTOR WORKED ON, SOMETIMES IT WON'T SHIFT COMPLETELY INTO PARK, I HAD IT DECREASE IN SPEED FROM 70 ON THE HIGHWAY TO NO MORE THAN 20 MPH WITH OVER $400 IN REPAIRS JUST THAT TIME. I DO NOT DRIVE FAST OR DEPRIVE MY CAR OF REGULAR MAINTENANCE. I HAVE NEVER HAD ISSUES LIKE THIS WITH ANY OTHER VEHICLE.
