AutoCheck does show service history, but usually less of it than CARFAX, and in less detail. An AutoCheck entry tends to tell you that a car was serviced, roughly where, and by what kind of business, without the line-by-line work you might see on a CARFAX. In Edmunds' June 2026 side-by-side test, CARFAX found 15 service records on a 2014 Porsche Boxster going back to 2014, while AutoCheck showed three, all from 2024. If maintenance history is the reason you are buying a report, that gap matters.
We went back through the Edmunds comparison, Capital One's Auto Navigator explainer and Autotrader's guide to dealer records on November 8, 2026. None of this means AutoCheck is useless. It catches title brands, auction history and odometer problems well enough to be worth running on a lot of cars. It just means you should not read a thin service section on an AutoCheck as proof the car was neglected.
What an AutoCheck service entry looks like
Capital One's Auto Navigator says an AutoCheck report only lists the city and type of business that did the maintenance or repair, such as a dealership or an independent shop. It does not promise the specific job. So you might see that a car was at a dealer in a certain city on a certain date, and that is about it. Capital One also notes that AutoCheck reports on data provided by state agencies, insurance companies, repair shops, auctions and dealerships, so the service picture is only as good as which shops happened to report.
Edmunds' comparison table puts it bluntly: CARFAX has "more detailed maintenance and repair info" and AutoCheck has "less detailed maintenance and repair info." That lines up with what the Boxster test showed.
Why the two reports disagree
The reports are built from different data deals, so they rarely match line for line. In Edmunds' testing, the same Boxster showed five owners on CARFAX and three on AutoCheck, because CARFAX counted the dealerships that held the car between owners and AutoCheck counted only the people who bought it. On a 2017 Honda Accord with a salvage title, CARFAX listed front damage from November 2024 that AutoCheck had not picked up when Edmunds ran both reports in early December 2024. Edmunds' take was that CARFAX seems to get its data more quickly.
The same mismatch shows up in owner counts, accidents and title dates. Our post on why CARFAX and AutoCheck disagree covers the general reasons, and what each report catches goes through the categories where one tends to beat the other.
Where AutoCheck's data comes from
Per AutoCheck's FAQ, the records are pulled from several hundred places: DMVs in each state and in Canada, auctions, dealers, and consumer protection and other state agencies. That mix explains its strengths: title brands, auction runs and odometer readings at sale time are the kind of thing those sources record well. Oil changes at a quick-lube shop are not. The FAQ also says AutoCheck reports on accident damage when that information is provided to it, and that a "no records found" result can simply mean nothing has been reported yet, or that the car predates the modern 17-character VIN. AutoCheck covers vehicles built for the U.S. and Canadian markets only, so a gray-market import may come back nearly empty.
A thin service section is not automatically a red flag
Capital One makes the point that a big gap between oil changes, or missing scheduled maintenance, on an AutoCheck report is not necessarily a red flag. Plenty of shops do not report, and plenty of owners change their own oil. That is true. It is also exactly what a seller will say about a car that really was neglected, so the gap is a reason to ask questions, not a reason to relax.
- Ask the seller where the car was serviced and whether they kept receipts. A shoebox of invoices beats any report.
- Call a franchised dealer for the brand. Autotrader says dealers can often pull records for work done at manufacturer-authorized service centers, though some will refuse over privacy concerns, since the records can include the old owner's address and phone number.
- Remember that independent shop work will not show up in a dealer's system, per Autotrader, so a dealer printout with gaps is not the whole story either.
- Get a pre-purchase inspection. Autotrader recommends one on nearly every used car, and a mechanic looking at the oil and the belts tells you more than any database.
Our guides on service record gaps and what service records mean on CARFAX cover how to read the CARFAX side of this.
Which report to buy when service history matters
If maintenance is your main worry, on a performance car, a turbo engine or anything with an expensive timing service, run the CARFAX. If you are screening several cars for title brands, auction history and odometer problems, AutoCheck does that job at a lower price and adds its score, which our AutoCheck score guide explains. On a car you are serious about, running both is cheap insurance.
On price, Edmunds listed CARFAX at $44.99 for one report and AutoCheck at $29.99 when it gathered prices in June 2026. Its own page is inconsistent on the AutoCheck five-pack, listing $59.99 in the table and $49.99 in the text, which tells you how slippery these numbers are. Through us, a licensed reseller with no affiliation to CARFAX, AutoCheck or Experian, a single report has recently run about $5.50 as a guest or $4.50 as a member, and both together about $6.75. Confirm at checkout, because prices change.
