Does Refinancing Your Car Loan Hurt Your Credit?
On this page
The short answer: a little, temporarily. Refinancing involves a hard credit inquiry prior to funding the loan which typically drops your score slightly. That dip recovers within 3–6 months. For most borrowers, the interest savings from a lower rate far outweigh the temporary impact.
What Happens to Your Credit When You Refinance
Step 1: Rate check - no impact
Checking your rate with Tenet is a soft inquiry. It doesn't appear on your credit report and doesn't affect your score. You can review real offers without any credit impact.
Step 2: Full application - small, temporary impact
If you proceed, a full application triggers a hard inquiry. This typically reduces your score by 5–10 points and shows on your report for two years, though the score impact fades within 3–6 months.
Step 3: Account changes
When your refinance closes, your old loan is marked "paid in full" (positive) and a new loan account is opened (initially shortens average account age — a minor negative). The net effect is usually small and temporary.
Rate Shopping and the 14-Day Window
Credit scoring models treat multiple auto loan inquiries within a short window as a single inquiry. The window is typically 14–45 days. In practice: comparing offers from multiple lenders within two weeks counts as one inquiry. Concentrate your applications within that window.
Note: Some banks do not pull credit under the auto loan code but may use a general code, this can increase the impact to your credit. It's best to check offers only with soft credit and just do a hard credit inquiry with the lender you go with.
When the Savings Outweigh the Impact
A borrower with a $35,000 EV loan at 9% APR refinances to 5.75% with 36 months remaining:
- Old loan remaining interest: ~$5,100
- New loan total interest: ~$3,050
- Interest saved: ~$2,050
- Credit score impact: 4–5 months
For almost every borrower, $2,050 in savings is worth a temporary dip.
The calculation only goes the other way if your score is at a tipping point for something important, like a mortgage application, in the next few months. In that case, wait until after the mortgage closes.
When to Avoid Refinancing
- Major loan application coming up in 60-90 days. Delay until after.
- Your score is already low and close to a lender minimum. Work on improving your score first.
- Loan remaining principal balance. Tenet's minimum financed amount is $10,000, the savings on lower balances are also smaller.
The EV-Specific Case for Refinancing
EV owners benefit more from refinancing than gas-car owners because loan balances are higher. A 1.5% rate reduction saves more in absolute dollars on a $40,000 EV loan than on a $25,000 gas car loan. EV owners who refinanced in Q1 2026 saved an average of $209/month.

Frequently Asked Questions
How many points does refinancing drop my score?
Typically 5–10 from the hard inquiry, plus a possible additional temporary dip from the new account. Combined effect: usually 10–20 points, recovering within 3-6 months.
Can I refinance multiple times?
Yes, but each involves a hard inquiry. Wait at least 12 months between refinances.
Will refinancing affect my ability to get a mortgage?
A hard inquiry from an auto refinance is a minor factor. More significant is the new monthly payment in your debt-to-income ratio. If you're applying for a mortgage within 60–90 days, the initial credit score impact may outweigh the lower debt-to-income ratio.
One Last Thing
There is a credit impact to refinancing but it is small and temporary. The interest savings are immediate and persist. For most EV owners with a rate above 6.5% on a balance over $15,000, the math clearly favors refinancing.
Checking takes two minutes and costs nothing, not even to your credit score.
