2018 Volkswagen Tiguan

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.

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.

The contact owns a 2018 Volkswagen Tiguan. The contact stated that while driving at various speeds, there was a clunking sound coming from the vehicle while depressing the brake pedal and making left turns. The contact stated that the failure became worse over time. The vehicle was taken to the local dealer to be diagnosed, and it was determined that the steering rack mounting bolt was fractured due to corrosion and half of the bolt had seized. The contact was advised that the steering rack needed to be replaced. The vehicle was not yet repaired. The contact was notified about NHTSA Campaign Number: 26V590000 (STEERING). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 82,000.

My vehicle is under safety recall NHTSA 26V590 (Volkswagen 48LG / 48VT). The steering rack mounting bolt can corrode and break, which can cause a loss of steering control. I was notified of this recall about a month ago. As of October 21, 2026, there is still no remedy available, and I am told owner letters may not go out until around November 10 — nearly two months after the recall was announced — with no date for when a repair will actually exist. This is my only vehicle, and I have to commute to work in it every day. On October 21, 2026, I contacted Volkswagen customer care and asked for a loaner or alternative transportation until the remedy is available. I was offered nothing — only told to keep driving the vehicle and wait. I do not think it is acceptable for owners to be told to keep driving a car with a known steering defect, with no repair available and no alternative transportation offered. I am asking NHTSA to press Volkswagen on the remedy timeline and on providing interim transportation for owners who have no other vehicle.

Within 6 months of purchasing car CPO from dealer, car went into limp mode. Was less than 35k miles, still having same issues at 85k miles. Took to dealer, they said nothing was wrong with car. Car began to have ECU light come on frequently in the middle of driving, took back to dealer. They replaced the fuel injector harness under warranty. Began to have issues with fuel injector misfires, car stalling and lagging at stop signs, sputtering when given gas. When driven for long periods at a time, would intermittently not start. Took back to dealer within a year, spent 1800 on maybe fixes, modules and carbon filter replacement. Same issues. Took back again, spent another 1800 replacing modules. Same issues repeated. Took to a european car specialist as we were frustrated with not getting the vehicle properly fixed for years at the dealer, had the engine walnut blasted for any carbon buildup and fuel injectors cleaned, they diagnosed and said the fuel rail harness is bad. Took back to Volkswagen, they re-evaluated and said there was no issue- my husband had to explain to them that there was a repair just done so code reading would not be sufficient and they needed to get under the car and use a multimeter to diagnose the wiring harness. Service team needs additional training- after doing so they found the fuel harness used may in fact be bad and replaced it a second time. Called VW corporate who was no help and told me we are at the discretion of the dealer and they years of the same issues are just what happens at times when the vehicle is out of warranty. There are thousands of reports online- I have been out of use of the vehicle for at least 6 months in my 5 years of ownership. I cannot believe that VW has consistently faulty product relating to the fuel rail system and has not recalled the vehicles.

Suspected Electrical Defect and Potential Fire Hazard – 2018 Volkswagen Tiguan SEL I am reporting a suspected electrical safety defect involving the sunroof wiring harness in my 2018 Volkswagen Tiguan SEL. While my vehicle was parked, an attempt was made to replace a blown F23 fuse. Smoke began coming from the sunroof area and filled the cabin. Afterward, multiple warning lights illuminated, the vehicle displayed a “turn car off” warning, the door locks repeatedly cycled, the climate control stopped working, and the infotainment/navigation screen shut off and restarted. A mechanic subsequently determined that the sunroof wiring harness had melted and required replacement. I was informed that the wiring harness (part number 5NA971648C) is unavailable and has been placed under Volkswagen’s “quality inspection” process due to suspected fire-hazard concerns. Volkswagen reportedly no longer supplies this harness separately, requiring replacement of the entire sunroof assembly, including the glass, even though the glass is not the source of the problem. The repair is estimated at $3,900 and requires extensive labor, including dashboard removal and a VIN-specific part from Germany. My primary concern is safety, not cost. A wiring harness that melts and produces enough smoke to fill a vehicle’s cabin could potentially cause a fire, damage other electrical systems, or endanger occupants. I am concerned other owners may face the same hazard. I request that NHTSA investigate whether the sunroof wiring harness or associated electrical system in 2018 Volkswagen Tiguan vehicles presents a safety defect, review similar reports, and determine whether further investigation or corrective action is warranted.

While opening the sunroof, the front end of the sunroof began to billow smoke. The cabin filled with smoke. The car was immediately turned off and the fuse was removed. While attempting to drive the vehicle closer to the dealership, the car experienced a total electrical failure and stalled on the side of the road. The car will require a tow. There is a known recall on this matter, however, my VIN does not fall under this recall. The recall explains the exact issue we experienced with the smoking sunroof motor from the faulty lighting causing a serious fire risk.

We have to add 1-2 quarts of oil every 600 miles. Our check engine light came on 02/2026 for carbon buildup. We had it cleaned, had timing chain replaced, piston rings, oil valves, manifold. Cost us $5300. The car ran fine before the light came on and all of a sudden it started making grinding noises and idling rough. We change the oil every 3,000 miles and the car burns through oil constantly. Our car stalled 4 times on the highway since then almost causing wrecks, it runs rough and now our check engine light is back on for the same issue. It’s causing emotional and financial distress. There are multiple lawsuits pending for this but something needs done. This is exhausting.

The car went into limp mode on an Interstate Highway. It was taken to a VW dealer in Mooresville, NC after two other private garages could not diagnose the problem. Their is a current Factory Warranty Extension for 2017, 2018, 2019 VW Tiguan's. The dealer in Mooresville kept the car for two weeks. Drove it for over 100 miles. They claim They can see the code in the computer but it is not active so VW will not pay for the known problem. I feel this is a safety issue as the car will not only possibly go into limp mode at any time but when stepping on the accelerator when not in limp mode the exhibits another known fault. The engine initially sputters as if it is going to stall then accelerates very quickly.
