The vehicle has a recurring interior rattle / loose-trim concern involving interior panels, trim, speaker/subwoofer area, rear shelf, dashboard area, or related mounting components.

Visible wiring has become exposed in the windshield/A-pillar area. There is no airbag/SRS warning light at this time, and I am not able to determine from visual inspection whether the exposed wiring is related to the restraint system. However, this is a safety-sensitive area because it can contain or route electrical wiring near trim, sensors, and safety-system areas. Exposed or unsecured wiring in this area may create a risk of electrical short, damaged wiring, impaired signal integrity, loose trim, moisture...

intrusion, or safety-system malfunction. The concern was reported as part of broader electrical and safety-related issues. No crash, fire, injury, or fatality occurred.

The vehicle/component is available for inspection, and photo evidence and service communications are available.

command the front air bags to also deploy and as a consequence further states, if the front air bags do not deploy in the event of a secondary impact to the front of the vehicle, there is an increased risk of occupant injury. Traffic was stopped on the highway and you could clearly see brake lights and the slowing of traffic for quite a distance. I travel this area regularly and am aware of the construction that causes traffice to slow. The truck ahead of me stopped, I was at a complete stop, the car behind me stopped then a a car hit me from behind, my car was pushed into another vehicle a car length ahead of me. My airbags did not deploy, my head hit the steering wheel. My car was also pushed sideways into the concrete divider. When I read the recall, it is exactly what happened in my car. My car was manufactured october 28, 2014. Why did they not deploy? Please advise as this was a serious situation and I am dealing with a brain injury. There was a fatality as well. *Tt *dt *tr

Rear window of convertible soft top for 2004 audi a4 cabriolet. An old issue often suffered by audi cabriolets from 2003-2009. Claimed to be caused by the adhesive that audi uses. This can be caused by keeping the car outside instead of in a garage as prolonged exposure to sunlight causes the adhesive to give away and fail, causing the rear window to separate from the outer layer of the top and drop. While the window is still technically attached to the inner layer of the top, the window no longer protects...

against water. As a result rain can seep into the non water resistant inner layer of the top and then cause water damage to the rear seats. This is the case with my own car and with a large enough number of cabriolets that this should have been settled frankly, a good 10 years ago when the first cases were being noticed. I have as many others have, attempted to use a temporary fix and as a result, there is a clear industrial adhesive around the top and rear window to attempt to fix this, it fails with continued use.
