Can they garnish my bank, take my car or money to collect insurance lien?

Are you asking about how bankruptcy will deal with your car and income?

Social security benefits are generally safe from garnishment. Presumably your bank account comes from SS benefits, so those funds are also exempt. Medical bills are dis chargeable in bankruptcy.

The medical provider had a lien on your recovery. Since you did not recover any money, you owe the medical provider for the service that you asked for and received. The lien is not the issue. The medical provider will have to get a judgment against you before it can garnish wages, levy bank accounts or take other judgment collection actions. Short of filing and proceeding with a lawsuit to get a judgment, the creditor can ask you to pay. It can send you invoices, notices, collection letters. It can call you at home or at work if you let them. If you are unable to pay and otherwise can benefit from bankruptcy protection, you will be able to get relief from the obligation to pay.

Money owed which is secured by a lien is collected much like other debts. The health care provider can sue you. OR they can go straight to the source of the funds you recover by settlement or judgment, and prove up their lien and demand payment. Quite often a good lawyer can negotiate the medical bills downward as part of the settlement of a personal injury case. But hospital liens attach to the money you get by way of settlement or judgment. If you don't receive any such funds, the liens have no value. The providers still have a claim against you, upon which they can sue if they think it is worth their while. Consult an experienced lawyer. Resolving this kind of question is one thing they are good for.

Social Security CANNOT be garnished, whether it's in the form of a check or in your bank account. Other income and assets, however, may be. You should definitely seek a consultation with a local lawyer who's knowledgeable in this area.

Medical liens (as opposed to medical debts that have a court judgment, which are judgment liens) affect the right only to receive insurance or injury settlement benefits. A medical lien cannot take other property unless there is also a court judgment.
