The contact owns a 2018 Volkswagen Tiguan. The contact stated that on several occasions while driving at undisclosed speeds, the vehicle started jerking. The contact stated that the EPC warning light illuminated, and a message was displayed on the instrument panel “Engine Speed - Max 4,000 RPM”. The contact stated that when the message was displayed on the instrument panel, the vehicle would decelerate to 15 MPH with the accelerator pedal depressed. The contact pulled over and turned off and restarted the vehicle. The vehicle was taken to the dealer; however, the failure could not be duplicated. The contact stated that she was informed by the dealer that the failure was a known issue and was due to a faulty transmission. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 92,000

When I first purchased my vehicle the epc came on multiple times and I had to take it back to the dealership. Fast forward last week when I was going home on the eway same issues car wouldn’t accelerate the car was idled at the speed of 40mph it wouldn’t go any faster for a few minutes then it took off out of no where. Also when I was taking my kids to school I was making a left turn and lost control of my vehicle because it was idled and took off out of no where. That’s not safe for me my kids or any passengers traveling with me. It’s also not safe for other drivers or pedestrians. Very scary moment took my vehicle in that same day to be told it was battery issues. They claimed because the epc light wasn’t on it’s harder to diagnose to get another battery and to keep the car overnight to see if that works if not further diagnose the car. I picked my vehicle up had my battery inspected by a different service provider and was told the battery was just fine. I keep reaching out to the location I got the vehicle from their not correcting the issue and corporate just told me to go to another dealership and gave a im sorry about your frustration comment. Clearly the car has a defect always had one since day one when it was supposed to be a cpo vehicle in the first place. And I had issues the same week I purchased the vehicle. Also haven’t had my car a year and I’m having all kind of issues

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. Compliance with the standard is based on the dummy injury criteria.Further, the Agency has conducted NCAP testing with no substantial protocol changes for over forty (40) years. This includes tests conducted prior and subsequent to the subject NCAP tests. During that time there has not been a similar failure of the seat belt webbing in any other NCAP tested vehicle manufactured by VW or another manufacturer.In November 2020, VW filed a defect notice (20V-724/69BH) that recalled seat belt systems, both driver, and front passenger, that were manufactured with webbing from the same lot as the two NCAP tested MY2018 Tiguan vehicles. VW has tested and inspected several of the returned seat belt systems and found no anomalies in either the webbing or the CLT that would substantially affect system performance in a frontal collision.The Office of Defects Investigation (ODI) estimates that between 2000 and 3500 frontal collisions involving MY2018 VW Tiguan vehicles have occurred in the field during the time these vehicles have been in service. This estimate is based on vehicle population and an estimated yearly rate of severe frontal collisions.A severe frontal collision is defined, in this instance, as being of sufficient severity to warrant a commanded deployment of the frontal air bags. These collisions would place a significant load on the seat belt system similar to loads experienced during the NCAP tests. To date, neither ODI nor VW is aware of any frontal collision in the field that resulted in separation of the seat belt webbing. ODI believes that had any field collisions involved separation of the seat belt webbing, the Agency would have been notified.In view of the recall being conducted by VW, and lack of field data demonstrating a system defect, ODI is closing this Engineering Analysis (EA). The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency reserves the right to take additional action if warranted by future circumstances.

PE18001 · Seat Belt Webbing Failure
Opened Jan 10, 2018 · Closed Jul 3, 2018
Status: closed (inferred from source dates) · Seat Belts:front:webbing
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 Transportation Safety Board (NTSB), verified the seat belts failed in tension and not due to cuts or abrasion.PE18-001 has been upgraded to an Engineering Analysis (EA18-005) to further examine seat belt behavior in the subject vehicles and to determine, among other things, a root cause for the seat belt separation. ODI will perform a thorough review of any vehicle and seat belt design changes for the new 2018 MY Tiguan platform and their effects on the performance of the seat belt system.
