Lemon cars are vehicles that have been repurchased by the manufacturer due to persistent defects. These cars often get resold at auction, and their history can be murky. A VIN lookup is the only way to know if the car you are looking at is a former lemon law buyback. The report will indicate a "manufacturer buyback" or similar brand on the title. This is a massive red flag, as the car may have ongoing issues that mechanics cannot fix. Vindecoderz helps you identify these problematic vehicles so you can avoid inheriting someone else's headache.
