NHTSA Complaint #11489885 — 2020 HONDA PILOT

The vehicle is showing the same issues as found in the Honda Service Bulletin 20-029 for "9-Speed A/T Hard Upshift with Steady Acceleration", and an occasional hesitation or slip. Our Honda Pilot has a Honda 6-Speed Automatic Transmission and AWD. The transmission has just had a full service, which included a "transmission fluid exchange to include torque converter lines" and replacing the transmission filter. When watching the vehicle shift, the tachometer will spike RPMs, then drop well below, and rise to settle in-between with a hard upshift. This issue was extreme prior to the transmission service, especially given the vehicle has only 49k miles and was purchased brand new. The constant hard shift and slip is a safety hazard.
