NHTSA Complaint #11477899 — 2017 CHEVROLET CRUZE

Have filed an earlier complaint and never heard back. But the engine was stalling and not maintaining speed without heavy acceleration. First week of August 2022 the car finally gave out after diagnosis of faulty knock sensor. Was displaying knock sensor code intermittently and finally stayed on. Anyway first week of august it stalled completely at a stop sign and would not crank back up. I finally started checking relays and found the engine functions relay faulty by accident. There are two square grey relays under the hood in the fuse block. One says engine function s relay and one says something to do with defrost controls. Had to swap the two relays to get my car running. No problems since. Only had 87,000 miles on car.
