Incident 1: Pulled out from stop sign car made funny noises, light came on said it couldn't shift to drive. Had towed to dealer. They said couldn't find issue except it was quart and a half low of transmission fluid. The car had approx 3,500 miles on it. Incident 2: For about two weeks when pulling out felt like it was skipping but didn't feel like transmission. Felt like over powered. Then it done same as Incident 1. Pulled out made noise would not move. Notice that is couldn't shift and check engine light came on had it towed again. Approx 6,300 miles on it. They then said it was very low on transmission fluid and they did find a small hole in hose. Danger is pulling out and it just stops in cross traffic and won't move could easily be hit. It is very scary to drive not knowing if or when it is going to happen. I have no current invoice on vehicle as it is still in shop.
