If you get a loan to buy your car in New Jersey and you fail to make your loan payment, then you could face having your car repossessed. It is ideal for you and your lender to avoid this situation. You would lose your vehicle, while the lender would end up with a car instead of the money it really wants. Furthermore, you would still be liable to pay off the loan even though you no longer have anything to show for it.
Avoiding repossession can be done legally, which means you do not do anything underhanded, such as hiding the vehicle, which would only lead to more trouble for you. According to Nerdwallet, the one thing you should do is talk to your lender before you miss a payment. You may be able to work something out. Make sure you know how much you can pay and when you can pay it, so you can offer something. It is not likely your lender will just let you skip the payment completely, unless you have been a stellar customer to this point. You also need to know whether this will be a one-time thing ro if you need a solution for the long term.
If this will be a long-term problem, you should consider refinancing to get a lower rate and lower your payments. You could also trade in your car and get one that is more affordable. Your lender may also have ideas for a solution.
The bottom line is you have to communicate with your lender. Keep in mind, your lender does not want your car. It is a hassle to repossess it and try to get their money from it. They would much rather have you meet your loan obligations, so they probably will work with you. This information is for education and is not legal advice.
