Answer:
Statute of limitations vary from loan agreement to loan agreement.
In Arizona, the SoL:
Oral agreement........3 years
Written contracts.....6 years
Promissory notes.....5 years
Open accounts.........3 years
Credit cards are considered open accounts while auto loans are considered as written contracts.
If a lawsuit has been filed, the SoL is different.
The judgment demand SoL in Arizona is 10 years, but can be renewed.
I suggest you talk to an attorney.
