A history report tells you what already happened to a car. The Genuine Interest Report tells you what to do next.
Give us the year, make, model, and the miles on the odometer. You get three pages you can print in about a minute, built from the manufacturer's maintenance schedule and the federal recall and complaint records for that exact vehicle.
The maintenance the factory schedule says should already be done at this mileage, with a line for what proof you were actually shown. Every row starts at "no record". Your job in the driveway is to turn those into a yes, a no, or a number in your offer.

For the seller
A plain, calm page that says what records you are asking for and asks whether you can take the car to your own mechanic. It carries no complaint quotes and no alarm language. A seller with receipts looks better after reading it.
Sheet 3
Hand this to your mechanic
Pre-purchase inspection sheet
A standard inspection list plus the checks that matter on this year and model, drawn from what owners have actually reported to the federal government. Room to write findings and a cost estimate.

What owners of this model report
Engine: complaints tend to arrive around 6 to 8.2 years old
At 10.6 years old, this car is past that age range. It is inside the mileage range at 95,400 mi. That is about 3.3x the engine complaint rate this same model usually runs across its other years.
Where owners gave an odometer reading, most fell between 65,000 mi and 113,000 mi, from 139 readings. Treat it as a hint. Based on 710 owner complaints filed with NHTSA.
Also elevated: structure, complaints tend to arrive around 4.6 to 8.2 years old, about 3.4x this model's usual rate. At 10.6 years old, this car is past that age range. Based on 107 owner complaints.

How to work through it
Say you want the car. Open with your interest, then say your report raised a few things to clear up.
Ask for the records. Walk the red rows above. Mark each one green as a receipt appears.
Pick your own shop. Do not use a shop the seller picks for you, and do not skip one they warn you off. Either way they are steering you.
Ask to take the car in. Get permission for a pre-purchase inspection. A seller who says no has told you something.
Set up the visit. Hand the seller Sheet 2. Hand your mechanic Sheet 3.
Add up what you find. Total the inspection findings and the red rows, then bring that number to the price talk.
About this data: complaint records come from NHTSA, where owners report problems themselves. That makes the data directional, and it is not a diagnosis. This report is a checklist and a conversation guide. It is not a verdict on the car in front of you, and it does not replace an inspection by a qualified mechanic.

Why you are seeing this
The buyer is serious about your vehicle. They are working through a standard set of checks before they buy, the same way a lender or an insurer would ask for paperwork. Nothing here says anything about how you cared for this car. Records and a routine inspection settle those questions quickly, and a car with proof in hand is an easier car to sell at the price you are asking.
What the records say about this model
Engine, a known pattern for this model
Federal complaint records show that for the 2016 Kia Sorento, engine complaints tend to arrive around 6 to 8.2 years old. This describes the model across the country. It says nothing about your car, which is exactly why the buyer is asking for records instead of walking away.
What the buyer is asking for
Any service records or receipts you have, especially for engine oil & filter and tire rotation. Even a folder of old invoices helps.
Whether the open safety recalls on this model were completed. A dealer can check the VIN in a minute, and the repair is free.
Permission to take the car to an independent shop for a pre-purchase inspection. It usually takes about an hour, and the buyer pays for it.
Why an inspection helps you too
An independent inspection helps both sides. The buyer gets confidence, and you get a written condition report that backs up your asking price. If the car checks out, the sale gets easier.
Records you have, and where they are
About this data: complaint records come from NHTSA, where owners report problems themselves. That makes the data directional, and it is not a diagnosis. This report is a checklist and a conversation guide. It is not a verdict on the car in front of you, and it does not replace an inspection by a qualified mechanic.

What the manufacturer's schedule calls for by this mileage, grouped the way the work actually happens, with a place to record the receipt you were shown.
The complaint window this car is entering
Where this year and model sits against federal complaint data, so an inspection starts with the part owners report most.
Open recalls on file
The campaigns recorded for this vehicle, and how to check whether this specific car has had them done.
What it will cost next
A price range for the services coming due in the next 12 months or 10,000 miles, at an independent shop and at a dealer.
Straight answer
What this is not.
This is not a mechanical inspection, and it does not replace one. We have no service records for the car in front of you, and we never guess at them. A red row means nobody has shown you proof yet. It is a question to ask, never an accusation.
Complaint data is what owners chose to report to the federal government, so it points at where to look rather than at what is wrong with this car. The report says so on every page.

About your email and your VIN
This is the one place on Wrench.Pro that asks for an email. We use it twice: once to send you the link to your report, and once about five days later to ask how the car turned out. There is no newsletter, and we do not sell it.
A VIN is optional. If you enter one, your browser holds it for this visit so the sheets can show it with the last digits hidden. We keep it out of the page address on purpose, because your browser prints that address at the bottom of every page you hand someone. Closing the tab clears what the browser was holding.
What you submit here is logged to our private spreadsheet, the same one every other form on this site writes to, so a person can follow up. Nothing you enter is shared with a shop.
