About The Lane Check: Used-Car Complaint Signal
Shopping for a used car? The Lane Check shows you what owners of that same model year told the U.S. government about it, on the listing itself.
Open a listing on Cars.com, Autotrader, CarGurus or Craigslist and a small card appears with:
- the share of NHTSA owner complaints about that model year that involve the engine, transmission or fuel system
- how that compares with the 1,790 model years we track (2010-2023, 200 models)
- the mileage at which owners said the problem showed up, where enough of them said
- a link to the full page: recalls, owner quotes and what to ask the seller
Built entirely on public NHTSA records. It describes the model year, not the individual car: it is not a vehicle history report or an inspection.
Private by design: listings are matched on your computer. The pages you view are never sent to us.
