2018 VW Tiguan. The fuel injector harness failed. There is a NHTSA letter stating 2018-2019 Tiguans had this issue and there’s an extended warranty up to 120,000 miles. My Tiguan is at 91,000 miles, but VW is saying the warranty isn’t assigned to my VIN. So there’s a warranty for this exact issue and year, but my vehicle isn’t covered. This warranty obviously needs to be extended by build date as it’s a pretty costly repair.

My 2018 Volkswagen Tiguan experienced a failure of the airbag control module caused by water intrusion through the HVAC access area and failed seam seal tape at the cowl support. The dealership confirmed that water leaked through a factory seam, accumulated at the airbag module, and caused the module to fail. The airbag warning light is illuminated, and the system is inoperable. This failure matches the same defect pattern covered under Volkswagen’s recall campaigns for the Atlas and Atlas Cross Sport (water intrusion leading to airbag control module failure), but my VIN is not included. The root cause and safety implications are identical: water entering through a body seam/HVAC area and compromising the airbag system. This is a safety‑critical issue that disables the airbags and creates a risk of injury in a crash. I am requesting NHTSA review this defect for potential recall expansion. Dealership Findings: • Water present at airbag control module • Water leaking through HVAC access hole • Failed seam seal tape at cowl support • Water accumulation damaging the airbag module • Cowl trim cracked and repaired • Recommended replacement of airbag control module and seam sealing tape • Estimated repair cost: $1,377 + tax Safety Concern: Airbag system is disabled due to water intrusion from a factory seam. This creates a risk of injury or death in the event of a collision.

I own a 2018 Volkswagen Tiguan with approximately 70,000 miles. The vehicle requires a full cylinder head replacement due to faulty valve seals. I have been having to add engine oil frequently between oil changes. The repair has been confirmed by an authorized Volkswagen dealership. The required cylinder head part is currently on manufacturer backorder with no estimated time of arrival. Dealership told me to check in every 2-3 months, as no additional cylinder heads can be ordered due to excessive backorder. Dealership charges $6,000+ for this repair. Volkswagen has not provided a solution or timeline for repair with this ongoing issue. There were no warning lights prior to the issue, and the vehicle has been routinely maintained. A major engine component failure at this mileage raises concerns about a potential defect rather than normal wear. This situation creates a safety and reliability concern, with no reasonable repair timeframe due to parts unavailability as well as no communication from Volkswagen regarding this ongoing issue.

This vehicle experienced a rear shock spring failure identical to the symptoms noted in VW recall 42i7. We paid out of pocket for the springs to be repaired, and VW corporate along with the dealer reported this VIN does not qualify for the recall. They are unable to tell me why our particular VIN does not, other than it simply wasn't on the list. It seems unlikely the exact year/model/failure occurred on our vehicle as what was stated in the recall but somehow it didn't qualify I would expect VW to cover the spring replacement and required alignment

On [XXX] I discovered water in my car. ~2.5 inch front passenger and back driver and passenger side. Condensation on the sunroof. My sunroof was not opened/completely shut. I called VW service was advised my car was not covered under the class action or warranty and advised to report to my insurance. I did not want to report and risk my insurance rate increasing. I have never filed a claim in the 20+ years of having the car. After researching and taking my call for repairs I discovered that my vehicle should be covered on the extended warranty IF the recall 60E5/60E2 was repaired. I am in Ohio where the damage was discovered my regular service dealer is in Illinois. 1)The service dealer in Illinois did complete the 60E5/60E2 recall. 2) the extend warranty % coverage should cover my car however I was told my VIN was not apart of the class action although the recall was performed an no record in the system with VW and if it were I would not be covered because I am 5 months out of the in service date. 3) the damage is ~ 3000.00 and increasing because now the sunroof switch doesn’t work and the screen is damaged from water. There is mold in my car which is a health hazard. I have exhausted trying to navigate through this issue! If my car was not apart of the class action it should have been. The insurance minus my deductible does not cover the cost of repairs. I have been without a call since this incident. This is a health hazard consumer driving hazard and should be investigated ASAP. I have attached the initial estimate which will be supplementally adjusted, the service 60E5 document . Please advise if this should be reported to the attorney general office and or what my next course of action should be.

2EA18005 · Seat Belt Webbing Failure
Opened Jul 3, 2018 · Closed Feb 27, 2023
Status: closed (inferred from source dates) · Seat Belts; Seat Belts:front; Seat Belts:front:webbing
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.

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.
Seat Belts
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.

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.
