Illinois Used-Car Complaints: What Buyers Should Check Before Signing

Used-car problems matter because they hit the household budget fast and are often expensive to unwind. That is why the Illinois Attorney General's consumer complaint list is useful: it points to the kind of transaction where buyers need a slower, more careful process.

What the complaint list says

On March 2, 2026, Attorney General Kwame Raoul said used motor vehicle sales complaints moved to the top of Illinois' consumer complaint list. The office also said it received 19,763 written complaints in 2025.

Why this matters before a purchase

A used car is often one of the largest purchases a household makes outside housing.
Financing terms, warranty language, and hidden repairs can create costs long after the sale.
The complaint list is a reminder to slow down before you sign, not after a problem starts.

Use this checklist before you buy

Check	Why it matters	What to do
Independent inspection	Hides less than a seller walkthrough	Pay a mechanic who does not benefit from the sale
Financing terms	Small rate changes add up quickly	Compare the APR, fees, and total amount financed
Warranty details	Verbal promises disappear fast	Get every promise in writing
Title and fees	Paperwork errors can delay ownership	Review every line before you sign
Repair history	Safety and reliability risk changes the price	Ask for service records and a clean explanation

Red flags that should slow you down

The seller pressures you to sign before you can inspect the vehicle
The monthly payment is emphasized more than the total cost
The dealer says paperwork details can be sorted out later
The story changes when you ask for a written promise

If something goes wrong

Save the listing, texts, emails, and signed documents.
Write down what was promised and when it was promised.
Report the problem early instead of waiting for the seller to stop answering.
Keep a record of repairs, receipts, and any follow-up calls.
