19V609000 · Electrical System:12v/24v/48v Battery:Cables

Reported: 2019-08-20 (August 20, 2019)

Thor Motor Coach (TMC) is recalling certain 2020 Chateau, Daybreak, Four Winds, Freedom Elite, Majestic, Outlaw and Quantum motorhomes. The battery cables may loosen on the battery isolation manager (BIM) or battery isolation relay (BIR), causing premature BIN/BIR failure or electrical arcing.

Consequence: The loose connection can causing arcing, increasing the risk of a fire.

Remedy: TMC will notify owners, and dealers will install lock washers to properly secure the battery cable to the BIM/BIR. If the cable was loose, dealers will also replace the BIM/BIR, free of charge. The recall began October 10, 2019. Owners may contact TMC customer service at 1-877-855-2867. TMC's number for this recall is RC000172.

19V775000 · Electrical System: Instrument Cluster/Panel | Seat Belts:Front:Warning Light/Devices

Reported: 2019-10-28 (October 28, 2019)

Thor Motor Coach (TMC) is recalling certain 2019-2020 Chateau 22B, 22E, 23U, 24F, 25V, and 28A, Daybreak 22GO, Four Winds 22B, 22E, 24F, 26B and 28A, Freedom Elite 22HE and 2020 Quantum GR22, and SE22 motorhomes. The seatbelt-unfastened warning light will not illuminate for approximately five seconds after the ignition is moved to the "on" or "start" position. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection."

Consequence: Without the seatbelt warning reminder, the driver may forget to fasten the seatbelt, increasing the risk of injury in the event of a crash.

Remedy: GM will notify TMC owners, and dealers will reprogram the instrument panel cluster, free of charge. The recall began October 3, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438, GMC customer service at 1-800-462-8782 or TMC customer service at 1-877-855-2867. TMC's number for this recall is RC000177.

20V308000 · Equipment:Other:Owners/Service/Other Manual | Power Train:Automatic Transmission

Reported: 2020-05-27 (May 27, 2020)

Thor Motor Coach (TMC) is recalling certain 2020 Daybreak, Four Winds, Delano, Gemini, Quantum, Tiburon, Chateau Citation, Compass, Chateau, Siesta, Freedom Elite, and Synergy motorhomes built on Mercedes-Benz Sprinter chassis [platform 907 (VS30)] equipped with automatic transmissions. The owner's manual does not correctly specify the certain conditions under which the automatic parking function (Auto-P) operates.

Consequence: If a customer were to rely on the Auto-P function as described in the Operator's Manual, the possibility of a vehicle rollaway or unintended vehicle movement cannot be ruled out which could increase the risk of a crash.

Remedy: TMC will notify owners, and a Mercedes Benz dealer will supplement the Operator's Manual with a correct description of the Auto-P function equipped in the vehicle. This recall began June 25, 2020. Owners may contact TMC customer service at 1-877-855-2867. TMC's number for this recall is RC000190.

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.
