With vehicle prices and monthly payments rising, consumers are taking out longer auto loans. In fact, in the fourth quarter, almost a third of the auto loans written were for a term of at least six years. By comparison, the number of borrowers scheduled to pay off their new car or truck in less than five years continues to drop, with just 18.7 percent of the loans having terms of 49 to 60 months.

All these increases in vehicle prices and auto loans has sparked renewed chatter that some borrowers may be getting over-extended.

Experian said 2.44 percent of borrowers were 30-days delinquent on repaying their loan in the fourth quarter, which is up slightly compared to the same time as 2015. By comparison, the percentage of loans with 60-day delinquencies edged up to 0.78 percent.
