No, currently there aren't any existing issues with the calculation of this new deduction in TurboTax. First, let's check your eligibility for the deduction, and make sure you qualify.
Per this article, 'What is the vehicle loan interest deduction?' there are multiple qualifying criteria:
You can deduct the full $10,000 if your income is under $100,000 (or $200,000 if Married Filing Jointly). If your income is higher, the amount you can deduct is less.
The deduction is available even if you don't itemize your deductions.
Do I qualify?
To get the deduction, your vehicle must meet all these rules:
It was purchased, not leased, in 2025.
It’s a brand new vehicle. In other words, you didn’t buy it used.
Its final assembly was in the U.S.
You can check this by entering your VIN and model year into the VIN decoder provided by the National Highway Traffic Safety Administration.
You’ll also include the VIN on your tax return.
It's a car, van, SUV, motorcycle, or pickup truck that weighs less than 14,000 pounds.
You bought it for personal use.
You didn’t pay the interest to a family member or a business you own. The loan must be secured by the vehicle.
Common questions
What if I use the vehicle for personal driving and business?
It’s OK to use the vehicle for your business, as long as:
The loan was a personal loan.
You also use the vehicle for personal driving (it isn’t only for business).
(added emphasis mine)
If you're certain that your vehicle purchase this year meets all the above rules i.e.,
the car is brand new and not used or leased,
you verified the VIN manufacturing history in the U.S.,
typed the correct VIN into the tax forms,
double checked the class and weight is < 14,000 lbs.,
and you've used it at least partially for personal rather than business driving, and etc.,
Then further investigation could be needed.
