One time the car Just Lost power on the freeway and the e-card engine light came on and the cat Ran rugh and stalled and jerked hard almost causing me to cause a serious accident...I took it to vw and explained the severity and they bypassed that And installed a new water pump..2months later the same thing happened exactly to where I was very lucky and very upset...and took it to them once again and explained more issues where I'm urging . As to the front warning light and motion has came into play a few times witch was shocking...also the car would be on slow mo mode....and constant warning lights would come on the dashboard as well as the car would feel so unstable and Feel as if it were On gear 1/L while in the drive position...also the Eco turn of feature would playout ..and stall from time to time..then the car would get stuck on speed when foot would come off the accelerator to brake before a stop sign or red light intersection witch just started to concern me and I again took these concerns to Rick case vw and They thought I was inventing this story..then the car leaked coolant..and it rusted out the whole bottom of my car ..hoses...and they replaced the thermostat this time around and now the car has misfired..could not start ..idle was ver rough and just vibrated dramatically and damaged coils and spakplugs and blew out fuel inject #2 and can't hold pressure past 30 ..changed out the spak plugs and coils and the car is just crippled and its a safety hazard and in many occasions has almost caused me to cause a serious accident...

While driving 70mph on the interstate in the middle lane with an 18-Wheeler next to me in the right lane, my can all of the sudden a warning for an over the 4000 max rpm and an EPC light, which caused my car to start loosing speeding no matter how much or hard I pressed the gas peddle, in a matter of a minute my car dropped from 70 mph to 40mph and had to hit my flashers.
On September 19th 2025, while driving on the highway at normal speed, the instrument cluster fuel gauge misread the fuel level and indicated that the tank still had fuel. Without any warning light or low-fuel alert, the vehicle suddenly lost power because it was actually out of gas. I was traveling with my boyfriend and our thr…

On September 19th 2025, while driving on the highway at normal speed, the instrument cluster fuel gauge misread the fuel level and indicated that the tank still had fuel. Without any warning light or low-fuel alert, the vehicle suddenly lost power because it was actually out of gas. I was traveling with my boyfriend and our three dogs. We became stranded on the shoulder of a busy highway as vehicles passed at 70–80 mph. The outside temperature was about 85-90 at the time. This created a serious safety hazard: The cluster’s inaccurate fuel reading prevented me from knowing we were nearly empty. The engine shut down unexpectedly, leaving limited steering and braking control as we coasted to the shoulder. We were exposed to high-speed traffic and extreme heat while waiting for assistance. Additional cluster/safety issues observed: No audible turn-signal “click” or indicator sound when using the blinker. No warning chime if the car is left running when the driver exits (for example, if the ignition is on but the door is opened or the key is removed). The vehicle is out of warranty, but the dealership diagnosed a failed instrument cluster and quoted about $2,500 for replacement. Why This Is a Safety Concern: The instrument cluster provides critical driver alerts. Inaccurate fuel readings, lack of turn-signal audio, and the absence of an engine-on warning chime all reduce driver awareness and can directly lead to dangerous situations on the road. Requested Action: I urge NHTSA to investigate whether the 2018 Volkswagen Tiguan’s instrument cluster/fuel-level system and related warning features contain a design or manufacturing defect and to consider a recall or other remedy to prevent accidents or injuries.

I originally started out at World Kia in Matteson, where I was approved for a newer vehicle. But then they suddenly changed their minds and tried to put me in an older car instead. That rubbed me the wrong way, so I went to their Joliet location hoping for better service. Boy, was I wrong. Even though they had already run my credit in Matteson, they reran it again in Joliet, which made no sense and damaged my credit even more. I really needed a car at the time, so I felt pressured and couldn’t walk away. After I bought the car, it broke down shortly after, and I was never given any paperwork about its condition or inspection. They sold it to me “as-is,” but I later found out that under Illinois law, used cars must be safe and reliable for at least 15 days or 500 miles, even when sold “as-is.” My car didn’t meet that standard at all. The car has suspension issues which is very dangerous. The mechanic stated to not drive the car at all it's a safety hazard and I could cause a major accident. There is no recall on my vin#, but several other owners have had the same issues based of the information on the website. I just want some kind of resolution. I'm still responsible for the car, which is so unfair. This has caused so much stress that I have no clue what to do. please help.

Our car frequently (several times per month) suddenly stops when it is coming to a STOP when the Stop/Start feature is trying to engage. We took it to the dealer, and VW replaced the starter. That DID NOT fix the problem. When the car stops, frequently at or when approaching intersections, the display says we need to stop the car immediately, and the car is stopped, making a high-pitched sound, like a dentist’s drill. This problem started well before our warranty was finished, but after going to the dealer many times (and even leaving the car with them for a considerable amount of time). We were told many times that they could not replicate the problem, and that their diagnostic tools could not find a problem. I requested help from the automaker, VW, and I was told that they only follow the dealer, even though we have had this problem many, many times, and that there was nothing they could do for us. This is a safety problem, and I have seen many similar complaints online. You need to look into this. This problem happens when driving. We cannot get it fixed, and it seems to pose a danger. When I put the date of the incident, I will put the most recent day this happened. Please note that this has happened more than 100 times, and seems to be getting worse. Please investigate with VW. This is a large problem, and it deserves an auto recall.

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.

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.
