In most cases, a 17-year-old cannot get a car loan even with a co-signer. Most lenders will not approve a loan that lists a minor as the borrower, because a minor can legally cancel the contract and hand the car back. The common workaround is for the adult to take out the loan in their own name while the teenager drives the vehicle.
Why Lenders Say No to Minors
The problem is contract enforceability. In most states, the age of majority is 18, and anyone younger is legally a minor for contract purposes. Alabama and Nebraska set it at 19, and Mississippi at 21. Contracts signed by minors are “voidable,” meaning the minor can walk away from the agreement and return the vehicle without owing the remaining balance.
That makes auto loans especially risky. If a 17-year-old cancels, the lender is left with a depreciated car and no legal way to recover the difference. Courts have held that a car is not a “necessity” like food, shelter, or education, so the exception that makes certain contracts with minors enforceable does not apply to vehicle loans.1Social Security Administration. Validity of Loans to Minors A co-signer does not fix this. The minor’s ability to void the contract sits with the minor, not with the adult who signed alongside them, so the underlying risk to the lender remains.
When a Lender Will Allow It
A small number of lenders do put 17-year-olds on the loan when a creditworthy adult co-signs. In that arrangement, the teen is the primary borrower and the adult is the co-applicant. The lender leans on the adult’s credit score, income, and existing debts to decide whether to approve the loan and what interest rate to charge. Strong adult credit brings a lower rate; weaker credit means a higher rate or an outright denial.
The co-signer is equally responsible for every payment from day one, not just a backup if the teen defaults. The full loan balance appears on the co-signer’s credit report as their own debt, and if payments are late or missed, the co-signer’s credit score drops and the lender can take legal action against them for the unpaid amount.2Consumer Financial Protection Bureau. Should I Agree to Co-Sign Someone Else’s Car Loan? Before signing, the co-signer should receive a written notice explaining that if the debt ever goes into default, that fact may appear on their credit record.
The Path Most Families Actually Take
Because most lenders reject applications with a minor on them, the practical solution is for the parent, guardian, or other trusted adult to take out the loan entirely in their own name. The adult is the sole borrower, and the 17-year-old drives the vehicle as a permitted driver on the adult’s insurance policy.
This sidesteps the enforceability problem. The adult owns the loan and is listed on the title, though many states allow the minor to be added as a co-owner. Once the teenager turns 18, or reaches the age of majority in states with a higher threshold, the loan can be refinanced into the young adult’s name if they have built enough credit and income to qualify on their own.
The trade-off: monthly payments made on the adult’s loan do not help the teen build a personal credit history, because the account is not in their name. A secured credit card or a small credit-builder loan can fill that gap in the meantime.
The Emancipated Minor Exception
A 17-year-old who has been legally emancipated by a court generally gains full contractual capacity and can sign an enforceable car loan without a co-signer. Emancipation effectively gives the minor the legal status of an adult for contracts and other civil matters. The specifics vary by state, but the result is that lenders no longer face the voidability risk that blocks most minor applications.
Emancipation alone does not guarantee approval. The emancipated minor still needs to meet the lender’s credit, income, and down payment requirements, which is a high bar for someone without an established financial history. Lenders may also be unfamiliar with emancipation orders, so the process can involve extra documentation.
What the Adult Is Signing Up For
Whether as a co-signer or the sole borrower, the adult is taking on the entire loan. The specific risks:
- Full liability. If the teen cannot or will not pay, the adult owes the entire remaining balance.
- Credit impact. The loan sits on the adult’s credit report, and any late or missed payments damage their credit score.2Consumer Financial Protection Bureau. Should I Agree to Co-Sign Someone Else’s Car Loan?
- Reduced borrowing power. The balance counts against the adult’s debt-to-income ratio, which can affect their ability to qualify for a mortgage, another car loan, or new credit cards.
- Legal exposure. The lender can sue the co-signer, garnish wages, or send the debt to collections without first pursuing the primary borrower.
The credit inquiry itself is a smaller issue but worth noting. A hard inquiry can temporarily reduce a credit score by up to five points.3U.S. Small Business Administration. Credit Inquiries: What You Should Know About Hard and Soft Pulls If the adult is shopping multiple lenders, submitting applications within a 14-day window helps, because credit scoring models typically count multiple auto loan inquiries in a short period as a single inquiry.
Rates, Down Payment, and What to Expect on Cost
Interest rates depend heavily on the adult’s credit profile. Borrowers with excellent credit may see rates in the 4% to 7% range, while those with damaged credit can face rates above 15%, and some lenders charge well over 20% for high-risk borrowers. Shorter terms of 36 to 48 months generally carry lower rates than longer terms of 60 to 84 months, though the monthly payment will be higher.
A down payment of 10% to 20% of the vehicle price is a solid target for a first-time borrower. A larger down payment reduces the amount financed, lowers monthly payments, and can help secure a better rate. It also provides a cushion against negative equity, owing more than the car is worth, which is a real risk since vehicles depreciate quickly.
Once approved, the borrower signs a loan contract and a Truth in Lending disclosure. The disclosure spells out the annual percentage rate, total finance charges, monthly payment amount, and other key terms, and is designed to let you compare offers from different lenders.4Consumer Financial Protection Bureau.

Moving the Loan Into the Teen’s Name Later
Once the teen turns 18, or reaches the state’s age of majority, and has established their own credit history, they can work toward getting the adult off the loan. Both the lender and the primary borrower must agree to a release, and lenders are generally reluctant because removing the co-signer increases their risk.5Consumer Advice – FTC. Cosigning a Loan FAQs The common options:
- Refinancing. Apply for a new auto loan in the young adult’s name only, which pays off the original loan. This requires a solid credit score, steady income, and a track record of on-time payments.
- Co-signer release. Some lenders build a release option into the original loan agreement, allowing the borrower to request removal after a set number of on-time payments. Check the contract or ask the lender.
- Paying off the loan. If the funds are there to cover the remaining balance, paying it off releases both parties.
Refinancing is the most reliable path for most young borrowers. Building credit through consistent on-time payments, along with a secured credit card or small credit-builder loan, strengthens the application when it is time to take the loan over independently.
