Visibility/wiper complaints
5 reportsDriver and passenger windows are fogging up unexpectedly which causes loss of view. This is very dangerous when driving as it is difficult to see my side mirrors.
PASSENGER SIDE WINDOW HAS STARTED FOR FOG OVER. MAKING IS MORE DIFFICULT TO SEE CLEARLY THRU THE RIGHT HAND OUTSIDE MIRROR.
VISIBILITY THROUGH FRONT STATIONARY PORTION OF DRIVER'S SIDE WINDOW IS COMPROMISED DUE TO INTERNAL "FOGGING" OF TWO-PANE GLASS WINDOW. REAR PORTION OF WINDOW SLIDES FORE AND AFT. AT SOME SUN ANGLES THIS FOGGING OBSCURES DRIVER'S VIEW OF LEFT SIDE MIRROR MAKING VIEW OF ONCOMING/PASSING TRAFFIC DIFFICULT.

See a list of the affected trailer models at: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17V758-5764.pdf.

Additionally, in certain models, the nozzle may detach from the valve assembly with enough force that it could cause injury and also render the product inoperable. For a full list of the affected fire extinguisher models visit: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17E062-5427.pdf

13V164000 · Equipment
Apr 25, 2013
Thor Motor Coach is recalling certain model year 2013-2014 Challenger, Four Winds 5000, Hurricane, Chateau, Chateau Sport, and Windsport; model year 2013 Palazzo and Four Winds Siesta and model year 2014 Majestic motorhomes manufactured February 13, 2013, through April 09, 2013. If the awning installation sequence was not completely followed, the awning motor may unknowningly become damaged. A damaged motor may lead to an unfurling of the awning.
Consequence & remedy
Consequence: If motor damage occurs, it is possible that the awning can unfurl unexpectedly, either while the motorhome is at rest or while in transit, increasing the risk of personal injury or a vehicle crash.
Remedy: Thor Motor Coach will notify owners and Dometic staff will replace the affected motors with a design that is not subject to an out-of-sequence installation error.

12V574000 · Electrical System; Exterior Lighting:brake Lights; Vehicle Speed Control:cruise Control
Dec 11, 2012
Thor Motor Coach (Thor) is recalling certain model year 2011 through 2013 Tuscany, Astoria, Ultrasport, Montecito, and Palazzo recreational vehicles manufactured from May 17, 2010, through October 30, 2012, built on Freightliner brand XB and XC custom chassis. The vehicles are equipped with diode jumpers that may come loose in their connectors resulting in an open circuit. Two circuits are affected: The one that disengages the cruise control with brake pedal use, and the one that illuminates the brake lights with brake pedal use.
Consequence & remedy
Consequence: Failure of the cruise control to disengage when the brakes are applied may increase the risk of a vehicle crash. Without the brake lights illuminating when the brakes are applied, the driver's intent is not communicated, increasing the risk of a crash.
Remedy: Daimler Trucks (DTNA) will notify owners on behalf of Thor, and Freightliner dealers will inspect the diode jumpers to make sure they are fully locked in place and will correct the vehicles as needed. The recall is expected to begin January 28, 2013. Owners should contact DTNA Warranty Campaigns Department at (800) 547-0712, 7:00 a.m. to 4:00 p.m. Pacific Time Monday through Friday, e-mail address DTNA.Warranty.Campaigns@Daimler.com, or the Customer Assistance Center at (800) FTL-HELP after normal business hours.
