Air Bag Clockspring Failure
In August 2015, Volkswagen Group of America, Inc. (Volkswagen) launched Safety Recall 15V-483 to address the loss of the protection provided by the front driver air bag in several models due to the failure of the clockspring.Debris entry into the steering wheel hub can result in contamination and ultimately failure of the clockspring in 2010-2014 Model Year (MY) CC, Passat, Eos, Golf, GTI, Tiguan, Jetta and Jetta Sportwagen models.Contamination of the clockspring can cause the ribbon cable to tear resulting in loss of the electrical connection to the front driver air bag and any steering wheel mounted controls.The loss of the electrical connection to the front driver air bag will result in illumination of the air bag warning light and will prevent operation of the front driver air bag in a crash of sufficient severity requiring a commanded deployment.In November 2017, the Office of Defects Investigation (ODI) opened a Recall Query (RQ17-009) after the agency received 90 complaints alleging failure of the clockspring in the subject models.Several of the complaints allege failure of the clockspring after receiving the recall remedy.The majority of the complaints allege the same failu
Seat Belt Webbing Failure
In December 2017, NHTSA conducted two (2) New Car Assessment Program (NCAP) tests on the Model Year (MY) 2018 Volkswagen (VW) Tiguan. Both tests were 35mph full frontal impacts into a rigid barrier with a 50th percentile male dummy seat-belted in the driver position and a 5th percentile female seat-belted in the right front passenger position. The tests were conducted on December 8, 2017, at MGA Research Corp. (MGA) in Wisconsin and December 13, 2017, at the Transportation Research Center (TRC) of Ohio.During both crash tests, the driver seat belt webbing completely separated at the point where the webbing loops through the Crash Locking Tongue (CLT). In both NCAP tests, the dummy injury criteria requirements, as set forth in Federal Motor Vehicle Safety Standard (FMVSS) 208, were met with one exception. The chest deceleration G force requirement was exceeded in the test conducted at TRC. The FMVSS 208 injury criteria requirement for the chest deceleration is 60 Gs and it was measured at 67 Gs in the test conducted at TRC. It should be noted, FMVSS 208 does not include a requirement that the seat belt webbing remain intact during a frontal collision to comply with the standard. Com
Seat Belt Webbing Failure
In December 2017, NHTSA conducted two New Car Assessment Program (NCAP) tests on the 2018 MY Volkswagen (VW) Tiguan. Both tests were 35 mph, full frontal impacts into a rigid barrier with a 50th percentile male dummy seat-belted in the driver position and a 5th percentile female seat-belted in the right front-passenger position. The tests were conducted on December 8, 2017 at MGA Research Corp. in Wisconsin (MGA) and December 13, 2017 at the Transportation Research Center of Ohio (TRC).During both crash tests, the driver seat belt webbing completely separated in tension where it looped through the seat belt latch tongue (see attached photos). Based on its analysis of the NCAP test results, VW asserted that the test dummy umbilical cord exerted additional forces on the seat belt system causing the separation. To support this theory, VW conducted several sled tests.The Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE18-001) on 01/10/2018 to evaluate the two (2) incidents of seat belt separation. ODI and NCAP reviewed the sled test data submitted by VW in support of their theory. Micro analysis, conducted by the Materials Laboratory at the National Transportat
About NHTSA Investigations
NHTSA investigations include Preliminary Evaluations (PE), Engineering Analyses (EA), Defect Petitions (DP), and Audit Queries (AQ). Investigations may lead to recalls if defects are confirmed. An open investigation means NHTSA is actively examining the issue.
