Recall 20V148 affects 227 2020-2021 Thor Sequence and Tellaro motorhomes for a transmission shifter cable defect. Repair is free at any franchised Thor dealer.
Thor is recalling 227 2020-2021 Sequence and Tellaro motorhomes because the transmission shifter cable can separate from the transmission, so the gear lever can show a different position than the actual gear. That mismatch leaves the driver without a reliable gear indication and allows unintended vehicle movement, increasing crash risk; Thor dealers will complete the recall repair free of charge.

What's wrong?
The transmission shifter cable on 2020-2021 Thor Sequence and Tellaro motorhomes is the link between the gear selector you move and the transmission underneath. When it is intact and adjusted correctly, moving the shifter tells the transmission to enter the gear you selected, including PARK.
On affected motorhomes, the cable was kinked during vehicle manufacturing. That bend damages the cable and can let it separate from the transmission connection. When that happens, the gear shift lever position no longer matches the transmission gear, so the motorhome does not perform the shift the driver intended.
The warning signs are on the instrument cluster. The displayed transmission gear shows the real gear position, and the cluster can show "Vehicle Not in PARK" and "Door Ajar" messages. Audible chimes sound if the driver's door is opened while the transmission is not in PARK.

What's the safety risk?
A disconnected transmission shift cable can leave the shifter out of sync with the transmission. The vehicle can move when the driver thinks it is in PARK, increasing crash risk. Watch the instrument cluster for the actual gear position, plus "Vehicle Not in PARK" or "Door Ajar" messages and chimes. Repair is free at any franchised Thor dealer.

- Bring the recall notice if Thor has mailed one. If not, reference recall number 20V148 when you call.
