Example complaints

Air bags: “Vehicle experienced a minor grazing impact on both right side doors (in the middle of an intersection), which deployed the right side airbags and also the airbag inside the front passenger leather seat. After the accident, the window glass didn't break, the doors opened and closed normally. The safety issue is that when the airbags deployed, the engine died immediately, as if from an electrical failure, and the steering wheel pulled to the right and the driver (me) had no braking. The car veered to the right and coasted to a stop in a yard at the far end of the intersection. …”

Then the next time I noticed a crack by the corner of the left dash speaker, then the next time the right dash speaker. Now I noticed a crack by the far right air conditioner vent on the dash.
