What owners are reporting 2 most recent
Transmission can pop out of gear when the shift handle is inadvertently nudged while driving. Also, when shifting into gear when stopped, the transmission will revert to neutral (pop into) in an emergency situation unless you hold the handle forcefully and in drive or reverse. Even with your foot on the brake. Both have recurred multiple times. Dealer has no solution. Genesis has no response.
When turning right or left from a stop, the transmission refuses to respond at times...it slogs down and will not shift to accelerate in a lower gear...an emergency situation could kill someone. The dealer has no solution. Genesis has no response. This has happened many times since 7/2017.
