I purchased this car from what I believed was a private individual for my 15 year old daughter as her first car. This individual knew the purpose of this sale and was accutely aware that a new driver would be the primary driver. Before allowing her to drive this car, I had a detailed safety and condition inspection completed by a local import repair specialist. They found that there had been a deployment of the air bags resulting in the clock spring and front seat belt retractors being unusable. In addition, the air bag warning light had been removed from the instrument cluster and the bulb was removed, disguising the fact that there was an issue with the air bags. …
CATASTROPHIC SAFETY ISSUE MANY of the warning lights on the instrument cluster are illuminated. These include: * ABS is steadily illuminated. * Airbag is steadily illuminated. * The speedometer is not functioning showing "0" so I can't tell how fast I'm going. * The steering system indicator light is steadily illuminated. * Check Engine/Engine Malfunction is intermittent. * The Electric Power Control indicator is intermittent. * ESP/ASR is steadily illuminated. * The Alternator indicator light is intermittent * Tire Pressure Monitoring is steadily illuminated. * The fuel gauge is moving ranging from empty to full therefore the low fuel indictor flashed frequently. * Several times when depressing the accelerator instead of gaining power, acceleration dropped off. In traffic, at highway speeds, this is an additional serious safety issue. …
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. …
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.
During a left hand turn a loud "pop" occurred in the steering wheel while illuminated the Air Bag error light and disabled the horn and all steering wheel controls. I called Volkswagen about the errors and was transferred around on phone system, hung up on while transferring, message left with no contact back. While searching online have found numerous air bag recalls with clock spring issues but this model is not showing it although it is obvious it has failed. The car is not currently safe to drive and is parked, I currently own 4 of these VW TDI Passat's and need this addressed. Thank You
