Purchased new 2016 Honda Odyssey van in MD in December 2016. 150 miles into our trip home to nc, just after washington DC, we hit stop and go traffic on I-95. The transmission started making clunking sound and shuddering when trying to go from 1st to 2nd (multiple times). You felt van was going to break and that you had no acceleration. Pulled off to side of road and turned off car � nothing was noticeable. Went to nearest dealer that was 5 miles away. Told this can be normal, as van computer needs to learn driving habits. Left dealership, traffic was again stop and go. Within 5 miles had same noise and shuddering, but this time got check engine light and flashing "d" on dash. Repeated again for 3rd time on return to same dealer. They examined car for 2 hours. Check engine code was: p0796 - a/t clutch pressure control solenoid valve c stuck off. However since code did not return after resetting, they could not fix it under warranty. We considered van unsafe to drive (regardless of 4 hour trip remaining). With no choice other than driving unsafe car, we traded it in and suffered significant depreciation for car we owned approximately 5 hours & 157 miles. Searches online and in the NHTSA database reveal this is not an isolated issue for this model, and Honda hides behind �not able to reproduce� after turning car off and resetting the check engine light.
