Honestly, I work for an auto dealership so I personally deal with carfax on an almost daily basis. Let me first explain how carfax gets their reports. Obviously, any servicing done by a known source gets reported IF they report to carfax. Not all, but most places do. If you have a big dealer, chances are they have 3rd party service like tint, bumper, paint and small repairs work at the dealer. So these things get reported in various ways. My experience is something small like a paint touch up on the front bumper has caused carfax to report "front end damage" on cars that never had "damage" like you'd expect from a fender bender. This is why carfax is a sham. It hurts everyone and does nothing good except recording miles (sometimes) and titling ownership. They will state their "very reputable third party connections " bring them incident reports even if a dealer has proof they had a paint touch up and they will report major damage on the carfax. If you despute good luck. They don't care. They want physical proof. Most dealers doing touch up paint for a scratch aren't going to photograph this because it isnt damage but carfax says otherwise. They also randomly add services to a vehicle up to 5 years ( that I have personally seen ) old. For example you pull a carfax today on your car and its clean but some how they pull a small bumper repair from 5 years ago and suddenly when you go to trade it your car it says accidents reported. Rear damage, major damage and it was the smallest tap to your bumper. Again, more headache then help. Honestly, you cannot buy a damaged vehicle from a licensed legit dealer without disclosing this information so carfax is obsolete. Lemon laws and other laws for the rightful sales of vehicles prevent you from buying a car that shouldn't be sold so carfax is a sham. It's fear mongering has caused more headaches then anything else I've dealt with in the automotive industry. 10/10 would never trust carfax.
