My wife was driving as she normally does to work, got off the highway exit and thought she hit a small patch of ice/slush and all of a sudden bells and whistles are going off telling her to Service Transmission, Service ECS and engine shuts off. Luckily she was able to coast to a safe parking area. Could not shift the transmission into any gear, not even park, so she engaged the e-brake. This vehicle has a push-button trans, everything is electronic so nothing seemed to work and we couldn't even get the car to turn off. It's less than 2 months old!
Had it towed to the dealer by dragging it onto a flatbed and then tow truck driver had to "shake" it off after pouring oil around all the tires numerous times after dealer tech couldn't figure out how to release e-brake. It's been there for a week and they haven't even started to work on it. Probably need a new trans and they said it would take at least a week to order once they diagnose. Blah.
Update from Mar 18, 2019: Apparently the wire harness that goes to the transmission was rubbing against a miscellaneous stud and wore through causing the system to short out. Removed extraneous stud and repaired wire harness. Has been fine since.
