The airbag system/clockspring assembly in the steering column appears to have failed. The airbag warning light turned on and all steering-wheel controls stopped working at the same time, which indicates that the driver airbag may not function in a crash. The vehicle can be inspected upon request. This is a major safety risk because the primary airbag might not deploy during a collision, putting the driver at high risk of injury. The issue has remained constant since it first appeared. I had the vehicle inspected by a highly reputable independent repair shop, and their assessment was that the clockspring/airbag component has failed. They advised that the necessary replacement part is unavailable to order, leaving the vehicle without a functional airbag system. I have also seen many other owners of similar 2015 Passat models reporting the same failure online, which suggests this may be a widespread defect. The airbag light is the only warning I received. It turned on a few months ago and has stayed on continuously since. UNKNOWN if there are other related electrical faults.

Gas and Oil comsumption is way too high … Almost every 600-1000 the low oil lights turns on! Check engine on almost all the time due to an error with the oxígen sensor. EPC light gets on very frequently and the car loses speed. Also vehicle has a constant rattlesnake sound when speed is low. Issue was reported some years ago to a local VW dealership in Georgia but they never took care of the issue. Ongoing for a couple of years!. No additional details

I take my car to the dealership for maintenance when it is scheduled. The ignition would not allow me to put the key inside. I did a little internet research and it seems to be a common problem with this car. I could not put the key in the ignition. I then used some wd40 and got it to go in eventually but thought I should report it as this could pose a safety hazard.

Failed part: Clock spring. Yes, the work was appropriately installed. This is my fourth replacement within less than 100k miles. No additional inspections as of yet. No warning lights, just a faint click coming from the steering wheels while making turns two days prior to hearing a snapping noise. My air bag light illuminated and my dash notified me of an air bag error. Lost all connection to steering wheel controls and horn. This is the same thing that has happened every time prior. The car is inoperable, once again, due to clock spring failure. I cannot drive my vehicle as I am concerned about not having safety features of an air bag and a horn. This has been an ongoing issue with VW. I have been the only owner of this vehicle for almost nine years.

Mice and rodents just love eating various electrical wires, vacuum lines, diesel fuel lines (both from tank to engine & return lines), etc. Never once had any animals issues with my other vehicles. Discovered that VWoA thought it would be a brilliant idea to use Soy in the manufacturing of electrical insulation, fuel hoses, vacuum lines, etc. ANIMALS LIKE EATING SOY. Very frustrating. My vehicle has been disabled before and one time I sprang a nice leak, leaving a trail of diesel behind me. Since all repairs and parts were ordered and conducted at local VW dealership. All records are both on carfax & stored in VWoA servers.
