Transmission won’t engage just revs, tried putting in reverse works, then drive makes a bang then goes in gear. Towed to dealer they couldn’t find issue first then found said it was solenoid they changed valve body. Then issue with codes they changed mechanics unit now it worked. Gave it back now it did it again but they could find issue for a few days had pick up at dealer. Car did it again at dealer they kept it and they can’t find issue still or recreate it. Not fixed still at dealer. I’m worried if they give it back and car goes while entering highway and I get rear ended, or it does something crazy like take off at crosswalk it’s totally unknown and can be dangerous. I’m calling corporate next.
