When describing what happened with your vehicle, tell us specifically if the vehicle was stationary, in motion, on a city street or a highway, turning, braking, etc. Describe the fault or problem that created the unsafe condition. If you know, state the component part or system that you believe may be the cause of the safety risk. If you are uncertain, simply state UNKNOWN and provide your best assessment of the incident and cause in your description. If you have other information - repair invoices, police accident reports, insurance claim forms, etc. - scan them electronically and upload them along with your complaint. If your complaint is about a recall and you have the recall number available, please provide it. Additionally, if you later obtain information and evidence related to your complaint, please retain it for at least five years, in the event that we contact you for further information.
