OneAZ Credit Union Auto Loan: Rates, Minimums and Checks

OneAZ Credit Union in Arizona posted auto loan APRs starting at 4.95% for a 48-month term on its rates page, with rates as of November 1, 2026, when I read it on Nov. 5. The same ranges applied to new and used vehicles, and every term topped out at 18.00% APR. Longer terms have loan minimums attached. The page does not say a CARFAX is required, but a used car still needs a clean title the credit union can put its lien on.

Rates by term

The table listed 4.95% to 18.00% at 48 months, 5.15% to 18.00% at 60 months, 5.45% to 18.00% at 72 months and 5.95% to 18.00% at 84 months. The 72-month term needed at least $15,000 borrowed, and the 84-month term needed at least $20,000. That spread from under 5% to 18% tells you how much your credit file matters here, so the floor is a best case. The posted rates also include a 0.25% discount tied to OneAZ Benefits Checking, which means the rate without that account would be a quarter point higher.

Large loans

OneAZ adds to the rate on bigger balances. Per the rates page footnotes, loans from $75,000 to $99,999.99 carry an extra 0.50%, and loans from $100,000 to $150,000 are capped at 100% loan-to-value with an extra 1.00%. Most used-car buyers will not hit those levels, but if you are shopping a late-model truck or a luxury SUV, check where your balance lands. A small extra down payment can keep you under the line.

Same rate for new and used

Because OneAZ lists the same ranges for new and used, a used car does not carry a built-in rate penalty on the posted table. That makes the condition and title of the car the bigger risk. We have seen buyers chase a low rate and skip the history check on the car itself, then find a branded title at funding. Pull a report, compare odometer readings over time, and read our guide to odometer disclosure rules if the mileage on the paperwork looks off.

Does OneAZ Credit Union require a CARFAX?

Credit unions generally care about the title, the value and the lien, and their published pages rarely say a history report is required. They do need a clean, transferable title so they can record their lien, and an older or branded car can change the rate or the loan amount. Our financing a rebuilt title car guide covers why branded titles get harder to finance. Pull a report before you apply, not after, so a surprise brand does not show up at funding.

Checks to run before you sign

• Run the VIN at the NHTSA recall lookup for open campaigns.
• Check title brands through an approved NMVTIS provider.
• Pull a history report and compare mileage readings over time.
• On a private sale, confirm the seller's lien is paid off. Our lien release guide walks through that step.
• Get a pre-purchase inspection on anything out of warranty.

Questions to ask the loan officer

• What exact APR and term would I get on this specific car, by VIN and model year?
• Does the rate change for a private-party sale versus a dealer purchase?
• Is there a maximum vehicle age or mileage, and a minimum loan amount?
• How long is a preapproval good for, and does the rate lock with it?
• Will you finance a car with a rebuilt, salvage or out-of-state title?

Dealer sale or private sale

At a dealer, the dealer usually handles the title and sends it to the lender. In a private sale, the credit union often pays the seller or the seller's lender directly and then waits for the title to arrive with its lien recorded. That takes longer, so plan for it. Do not hand cash to a private seller before the lender confirms the payoff and the title path. Our private-party CARFAX guide covers what to check on the seller's side.

Compare the offer, not just the rate

A low advertised APR only helps if you qualify for it and the term fits your budget. Ask for the exact APR, term, payment and total interest in writing, and compare it with a dealer offer and at least one other lender. The CFPB auto loan tools explain how to read a loan estimate. Decide on add-ons such as GAP coverage on their own merits; our GAP insurance guide covers when it makes sense.

What the report costs

As of early November 2026 a CARFAX bought direct usually costs around $44.99, and AutoCheck sits a little lower. We are a licensed CARFAX and AutoCheck reseller, not affiliated with CARFAX, AutoCheck or Experian. Our guest price has been about $5.50 a report, about $4.50 for members, and about $6.75 for a CARFAX and AutoCheck bundle. Confirm the price at checkout, since it can change.
