Procedure; Aircraft
The first strange thing the aircraft did was on departure at ZZZ; at 10;000 ft.; the GWPS system advised ' terrain pull up'. There was no terrain at that altitude or on our path. We were descending on the ZZZZZ arrival into ZZZ1; prior to reaching ZZZZZ1 intersection the aircraft Autopilot disconnected with a warning autopilot fail EICAS message. I hand flew the aircraft and had the PM (Pilot Monitoring) run the QRH. I continued on to the airport hand flying. Once we touched down the aircraft EICAS started to display many messages; Autopilot elevator mistrim; auto trim fail; autopilot aileron mistrim; and the pitch trim was moving full down on its own. Also there were some erroneous roll trim indications.Cause was total trim fail.Proper full inspection of aircraft in regards to these failures; we were very lucky these failures did not occur inflight so low to the ground during approach and landing phase.
Captain reported autopilot failed and disconnected on approach with false EGPWS warning. After landing; Captain reported multiple EICAS messages indicating a total trim failure.
