Warning Light On Problems of Volvo 850

The console and steering wheel were wet from rain. The srs dash warning light came on. About 5 miles after that, the driver's side air bag deployed. The bag was the original bag. The srs light had gone on once 20 months before when the console got wet. The dealership ran a test for about $115 each on both occasions and said the cause of the srs light coming on was indeterminate. Twenty months ago a top, longtime Volvo dealership service manager assured me that air bags never go off without an impact. He said there had not been a single occasion of that ever happening. I should have googled the topic. I would have seen right away that he didn't know what he was talking about. Two bones in my forearm were broken and heavy bruises that are still visible 5 weeks later were left on my stomach and thighs. Corporate offices and the dealership say the bag was out of warranty; a replacement steering wheel to install a new bag is not available; and that they will not disconnect the passenger bag, though I consider it a time bomb. Before writing an email attempting to place the blame on me, erica at "the executive offices of Volvo" left an apparently inane voice mail that I have saved for now saying "this is not exactly a spontaneous deployment. We do know why the bag deployed in your vehicle. " I emailed back that her claim that "we" know what caused the bag to deploy "struck me as odd because no one at the Volvo [dealership] this past week said that they knew. " even after running a check on the srs system, and charging me $115 to do so, they still said they did not know. In fact a few weeks ago two long time service managers were saying my experience was unprecedented or impossible. I suggested in another email to erica that the corporation had a moral obligation to inform their service managers of documented cases of spontaneous deployment.
