Vehicle just lost propulsion and would not move. Engine was running but just came out of gear and went into neutral at 70mph. Pulled off highway and vehicle would not go back into drive. Would not go into any gear except park. After a while it went into drive and would not go over 30mph. Limped into a nearby dealership and dropped it off. It took GM 47 days to figure out the issue yet the new part was installed immediately. Some sort of computer calibration glitch and GM didn’t know the answer till I threatened a lawsuit. Still not confident it was repaired correctly. Dealership was fine and informative but GM blew me off.
