Not sure if you guys know this or not but it was a shock to me when I went to trade my car in and was told there was an accident reported on the carfax.
I bought a two year old car in 2014 from a dealer, it came with a clean carfax, no reported issues. I went to trade it in last week and was told that the carfax showed an accident in 2014. I SAID NO WAY I HAVE A CLEAN CARFAX AND I WAS NEVER IN AN ACCIDENT. What I found out was that in 2016 someone reported to carfax that my car was in an accident in 2014. After numerous phone calls and emails found out that this is a common occurrence and carfax washes their hands of it. I was told to read their disclaimer which states:

This CARFAX Vehicle History Report is based only on information supplied to CARFAX and available as of ------ at 9:54:35 AM (CST). Other information about this vehicle, including problems, may not have been reported to CARFAX. Use this report as one important tool, along with a vehicle inspection and test drive, to make a better decision about your next used car.

Just wanted everyone to know that an accident can be added after you buy the car with a clean carfax.
