Owner report 11363961 · 2020-10-12 (October 12, 2020)
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.

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.

Recall history
2 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.
20V424000 · Seat Belts: Rear/Other:Buckle Assembly | Seat Belts
Reported: 2020-07-22 (July 22, 2020)
Thor Motor Coach (TMC) is recalling certain 2020-2021 Sequence and Tellaro motorhomes. The dinette booth seat belts may be too short preventing them from being usable by some occupants. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numbers 208, "Occupant Crash Protection" and 209, "Seat Belt Assemblies."
Consequence: Inability to use the seat belt may increase the risk of injury in the event of a crash.
Remedy: TMC will notify owners, and dealers will replace the 18-inch seat belt tether with a 24-inch tether on both sides of the dinette booth, free of charge. This recall began September 16, 2020. Owners may contact TMC customer service at 1-877-855-2867. TMC's number for this recall is RC000198.
NHTSA campaign record ↗23V285000 · Fuel System, Gasoline:Delivery:Hoses, Lines/Piping, And Fittings
Reported: 2023-04-21 (April 21, 2023)
Thor Motor Coach (TMC) is recalling certain 2021-2023 Sequence, 2021-2024 Rize, Scope, Tellaro, 2023-2024 Dazzle, and Twist motorhomes, equipped with certain Cummins Onan QG 2800i generator sets. The fuel hose between the inline fuel filter and the injection pump module (IPM) may have inadequate clamp force, possibly resulting in a gasoline leak.
Consequence: A gas leak in the presence of an ignition source increases the risk of a fire.
Remedy: Dealers will inspect and replace the fuel hose and clamps, as necessary, free of charge. Owner notification letters were mailed May 22, 2023. Owners may contact TMC customer service at 1-877-855-2867. TMC's number for this recall is RC000294.

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
2022: 3 complaints · 2023: 0 complaints
| Model year | Through age 0 | Through age 1 | Through age 2 |

Incident date is preferred when valid and no later than filing; otherwise filing date is used. Model year approximates age. Equal observation time does not adjust for sales, distance driven or reporting delays. One complaint linked to multiple model years can appear in each cohort.
