What happened when owners saw P1DA9?

3 of the 3 reports, spread across the models above, as the owners wrote them. NHTSA removes names and VINs; long reports are trimmed. CarHooq has not verified individual claims.

My vehicle drives about 30 miles before an alert will appear saying to service transmission. Along with the check engine light coming on. Vehicle will not accelerate and on hills will begin to roll backwards. When this happens the vehicle must be parked for at least 15 minutes and then on startup all codes will reset and return back to its normal operating. Took to dealership several times with error code P1DA9 and there was nothing that could be fixed.
