For Canadian Owners: This notice is sent to you in accordance with the requirements of the Motor Vehicle Safety Act. This is to inform you that your vehicle may contain a defect that could affect the safety of a person. Tiffin Motorhomes has decided that a defect, which relates to motor vehicle safety, exists on the following models of motorhomes: 2018, 2019, 2020, 2021 and 2022 Allegro Open Roads and Allegro Breezes built between February 23, 2017 and February 14, 2022 equipped with an optional 2000W inverter. Tiffin Motorhomes has become aware of the possibility that the nuts on each side of the buss bar may not have the correct torque applied. If the torque is not correct, this could create elevated temperatures on the buss bar which could lead to melting components on the DCD panel and in some cases, the overheating of the DCD panel could increase the risk of a fire. Tiffin Motorhomes will have the torque on the DCD panel checked and corrected as needed and will replace the existing buss bar with a 2/0 cable to handle the higher wattage of the 2000W inverter, as well as installing a new label with updated torque installed on the DCD panel. Please arrange to take your motorhome to a reputable service center OR dealer of your choice to have the correction completed. The recall repair will take approximately 1 hour and will be completed at no charge to you, the owner. If you are using a service center that is not a Tiffin Motorhomes authorized repair facility, please make sure that they contact Tiffin Motorhomes for the required instructions and time allowed for the repair. Tiffin Motorhomes will not pay over the allowed time unless the repair facility receives a prior authorization. For authorization, contact Tiffin Motorhomes at 256-356-0261 or service@tiffinmotorhomes.com . Page 2 of 2 You may be liable for any progressive damage that results from your failure to complete the recall within a reasonable time after receiving notification. Please note that the largest size of inverter that the DCD panel installed in the Allegro Open Road and Allegro Breeze can handle is 2000W. If owners have modified the inverter or replaced their inverter to one that is larger than 2000W, Tiffin Motorhomes is not liable for any problems incurred. Power over 2000W cannot be run through the existing DCD panel and needs to be removed. If owners have paid to have this repair completed, please send a copy of the invoice, that was paid by the owner to Tiffin Motorhomes at the following address: Tiffin Motorhomes, attn: Recalls, 105 2nd Street NW, Red Bay AL 35582 or by email to service@tiffinmotorhomes.com.
