CARFAX almost never shows a side mirror replacement on its own, because most mirror swaps are paid out of pocket at a parts counter or a glass shop that doesn't report. What can show up is the event behind it: a sideswipe or garage-door hit that went through insurance or got a police report usually lands as an accident with side damage. So a clean report doesn't prove the mirror is original, and a new mirror doesn't prove there was a real accident. You find out which one you're dealing with by looking at the car.
On an older economy car, a side mirror is a cheap bolt-on: a housing, a glass, maybe a motor, held to the door by three nuts under a trim cover. On anything from the last decade it can be a lot more than that. Plenty of mirrors now carry a turn signal repeater, a heating element, a power-fold motor, puddle lights, a blind-spot warning light, and on some trims a camera for the surround-view system. That's why a mirror swap on a newer car can run from a cheap aftermarket housing to a dealer part that costs real money, and the price spread depends so much on model and trim that you should get a quote for the exact car rather than trust a number you saw online.
Why the report usually stays quiet
The report only knows what its sources recorded. CARFAX says on its vehicle history reports page that it collects records from DMVs, insurers, police, auctions, and service and collision shops. A mirror clipped in a drive-thru and replaced with an online part never touches any of those. A sideswipe on the highway that crushed the mirror and scraped the door is a different story, since that's likely an insurance claim and often a collision-shop visit. We explain the size of that blind spot in unreported accidents on CARFAX, and minor accidents on CARFAX covers how small side hits get labeled when they do appear.
How to tell a mirror was replaced
Start with the color and the fit. Factory mirror caps are painted in the same booth as the body, so a replacement cap often looks a shade off in daylight or has a slightly different gloss. Push gently on the housing and see if it sits tight to the door the way the other side does. Then look at the glass itself: many factory mirror glasses have a small logo or etched marking in a corner, and a cheap aftermarket glass often doesn't, or it has a different tint than the passenger side. Fold the mirrors in and out, run the power adjust, and if the car has heated mirrors, turn that on and feel for warmth after a few minutes.
Honestly, the electronics are where a cheap swap bites you. If the car has blind-spot monitoring, check that the warning light in the mirror actually lights when a car passes in the next lane on your test drive, and look for a warning message on the dash. If it has a 360-degree camera, put it in reverse and check that the side view isn't black, warped, or misaligned. These driver-assist systems depend on sensors and cameras being placed and calibrated correctly, which IIHS explains in its overview of advanced driver assistance features. If a seller says a dead side camera "just needs a reset," it might, or it might need a part and a calibration. Price it as the second one until a shop says otherwise.
Check what the mirror is bolted to
A hit hard enough to snap a mirror off often marks the door too. Sight down the side of the car for a crease, look at the front edge of the door for chipped paint, and check the gap between the door and the fender at the top. If the door paint looks fresh or the panel gaps are uneven, read our guide to door replacement on CARFAX, and for refinished panels in general, paint work on CARFAX. A new mirror plus a repainted door plus a scraped fender is a sideswipe, and it should be priced like one even if the report is blank.
There are two other reasons a mirror gets replaced that have nothing to do with a crash. Mirrors are a common theft target on some models, which we cover in stolen side mirrors on theft-recovery cars, and a theft record may show up even when the mirror swap doesn't. Water damage is the other one: a power-fold motor that grinds or a mirror that stops adjusting can point to moisture inside the door, the kind of sign we walk through in mirror fold motor corrosion. If both mirrors are new and the car came from a flood area, look hard at the carpets and seat rails.
What to do before you buy
So ask the seller why the mirror was replaced and whether there's a receipt. "Somebody clipped it in a parking lot and I ordered one" is a normal answer. Then run the VIN yourself from the dash plate and the door jamb sticker rather than trusting a PDF the seller hands you, because we've seen edited reports with an inconvenient side-impact line removed. As of mid-October 2026, a CARFAX report through us runs about $5.50 as a guest or about $4.50 as a member, and a CARFAX plus AutoCheck bundle is about $6.75, compared with roughly $39.99 to $44.99 at retail; confirm the price at checkout since it moves. Check NHTSA's recall lookup while you're at it, since mirror glass, cameras, and turn signal repeaters have been recall items on some models. At a dealer, read the FTC Used Car Rule Buyers Guide on the window to see whether the car is sold as-is.
