My check engine light came on June 11, 2019 and was told I need a catalytic converter. Ok, I didn't like the price and wished it was under warranty but it wasn't. Regardless, it need my vehicle so I wanted to move forward to get it fixed. The part wasn't available and until July 5th and when I picked up the vehicle on July 6th, within 3 hours the check engine light was back on. So, the car is back at the dealership because the catalytic converter was faulty. Now, I'm in the same predicament as before, I don't have an ETA for the part. My car has been at the dealership for over a month and it's now July 22. This is unbelievable. I read another email about someone having a delayed transmission issue for 2 months. What is going on? I've sent my second email to GM.
