2015 Thor Motor Coach Siesta

Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

Latest Oct 8, 2019
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

The affected vehicles are equipped with certain Lippert-brand Coachstep Double and Triple Electric Steps. These steps use a bolt to attach the fan gear assembly to the steps.

The risk: Unstable entry and exit steps increase the risk of injury.
The remedy: Thor will notify owners, and dealers will install a retainer bracket to reinforce the operating mechanism and replace all of the affected bolts, free of charge.

The defect: Thor Motor Coach (Thor) is recalling certain model year 2015 Siesta and Citation motorhomes manufactured from September 26, 2014, through February 27, 2015, and built on a Mercedes-Benz Sprinter chassis. In the affected vehicles, the abutting wedge, a component attached to the door jamb to make opening the door easier after a severe frontal crash, may have been installed incorrectly.
The risk: If a vehicle that has an incorrectly installed abutting wedge is involved in a severe frontal crash, a greater force may be necessary to open the doors, increasing the risk of injury.
The remedy: Mercedes-Benz will notify owners on behalf of Thor, and dealers will inspect and, if necessary, correct the installation of the abutting wedge, free of charge. The recall began on March 23, 2015. Owners may contact Thor customer service at 1-877-500-1020 or owners may contact Sprinter Customer Service at 1-877-762-8267.
