One complaint can name several systems, so shares can add to more than 100 percent.
Confidence is the model's own probability for the label it chose (0 to 1), not accuracy.
Model-generated labels on tagged complaints only. Model years 2013 and newer are tagged in full; 2012 in part (see tagged_share); earlier model years have no tags. NHTSA's own flags remain separate in the complaints block.
Defect: Thor Motor Coach (TMC) is recalling certain 2018-2019 Quantum RW28 motorhomes. The vehicles may be missing the mid-ship marker lights. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."
Consequence: Without mid-ship marker lights, other drivers may underestimate the length of the vehicle, increasing the risk of crash.
Remedy: TMC will notify owners, and dealers will inspect and install mid-ship marker lights, as needed, free of charge. The recall began on April 25, 2019. Owners may contact TMC customer service at 1-877-855-2867. TMC's number for this recall is RC000167.
Defect: Thor Motor Coach (Thor) is recalling various 2003-2018 recreational vehicles, equipped with Kidde Plastic-Handle or Push Button 'Pindicator' Fire Extinguishers. See a list of the affected trailer models at: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17V758-5764.pdf. These extinguishers may become clogged, preventing the extinguisher from discharging as expected or excessive force may be needed (excerpt)
Consequence: In the event of a fire, if the fire extinguisher does not function properly, it can increase the risk of injury. (excerpt)
Remedy: Thor will notify owners, instructing them to contact Kidde for a replacement fire extinguisher, free of charge. The recall began on January 15, 2018. Owners may contact Thor customer service at 1-877-500-1020, or Kidde customer service toll-free at 1-855-262-3540, or online at www.kidde.com and click on "Product Safety Recall" for more information.

Notes on this record
Complaints from the API and bulk file are merged and deduplicated by ODI number; the API alone misses records.
System and subsystem counts are numbers of distinct complaints, recalls or communications that name them. One record can name several systems, so shares across systems can add to more than 100 percent; a single share never exceeds 100 percent.
Recalls are counted once per campaign, investigations once per action and manufacturer communications once per NHTSA id, even when NHTSA lists several model names for the same record.
A sales denominator is a calendar-year proxy, not the population of vehicles still in use. Rates are copied from verified pipeline output.
