Since purchase in April 2022, driver seat has side to side and up/down movement which is not part of the design, and appears to be unstable and potential safety hazard for driving. This movement does not occur in the similar swivel style passenger seat. Dealership stated seat issues would be repaired under warranty from Thor. Multiple repair attempts were made by authorized service provider (dealership) addressing other seat issues (not adjusting or rotating properly as designed), but excessive play in the seat still exists. Continued requests have been made to have this addressed in a timely fashion. Dealership and manufacturer have been questioned on whether there is potential safety risk for seat to come loose or dislodged during a collision due to this unstable movement, with no answers. Have seen multiple posts online that other Thor Class B owners are experiencing similar issue. LCI/Lippert (the original seat manufacturer) has been contacted and deferred us back to Thor, as they have agreement with Thor for ongoing service of these parts.

WHEN DRIVING THE VEHICLE AT HIGHWAY SPEED (I-90 ACROSS MONTANA AND DAKOTAS), THROUGH WINDY WEATHER, THE ROOF MOUNTED WINDOW WOULD POP OPEN AND BEGIN FLAPPING IN THE WIND. THE LATCHING MECHANISM GETS PULLED APART DURING THE WIND GUSTS ALLOWING THE WINDOW TO OPEN BY ITSELF. THIS IS DUE TO THE BAR HANDLE ON THE LATCH FLEXING ENOUGH TO POP OUT OF ITS TRACK ALLOWING THE LATCH MECHANISM TO RELEASE.
