Since January I’ve consistently had issues with my 2014 Chevy Sonic Hatchback, in particular, Codes 84, P2138, check engine light and traction control lights. (my job has us all working from home since March of 2020, so I only do local shopping, no long distance). Due to the codes mentioned above, my car was “repaired” at dealership on January 4, 2012. In the end of March I was constantly getting the same codes over a period of two days. I called GM (1 800 462 8782) on March 29, spoke with a woman by the name of Michelle and I explained what has been happening with the vehicle codes, along with other issues over the past year. She opened a case file # 9-6627321866 and she called the dealership to discuss my issue. I was told to drop the car off and it will be repair at no cost to me. The car was brought to dealership on April 7, 2021 and when the diagnostic was preformed, it showed no codes in the history. They did no repair at that time and gave me back the car. While running local errand on April 17, all the same codes appeared and once again I had reduced engine power. I was near the dealership and dropped off the vehicle, even though the service department was closed at that time. Once again, a new pedal and sensor was installed. I told them to please keep the vehicle for a few days, test drive it once in a while to ensure it is truly repaired. They test drove it several times during the 4 days they had it and since there were no issues, I picked the vehicle up on April 22, 2021.On June 5, while driving to a store a nearby store, I was stopped at a light to make a left turn and all the codes suddenly came on. I had very little acceleration making the left turn. The vehicle approaching me which was a block and a half away was now very closely approaching me and luckily realized I had an issue and stopped. I immediately headed back home. AutoZone ran a diagnostic and it's the same issue.
AT A STOP LIGHT/SIGN WITH MY FOOT ON THE BRAKE THE CAR WILL START TO SHAKE/LUNGE FORWARD LIKE THE CAR IS TRYING TO GO BUT CANT BECAUSE MY FOOT IS ON THE BRAKE. IT WILL HAPPEN WITHIN A MILE AFTER STARTING AND DRIVING MY CAR AND WHEN IT STARTS TO SHAKE IT WILL LAST MAYBE 5 SECONDS. IT HAPPENS 2 OR 3 TIMES A WEEK ESPECIALLY WHEN ITS COLD OUTSIDE. *TR
