It prevents gas fumes from being released when you aren't driving, it seals the fuel system and helps maintain pressure within the fuel tank. What happens if you have a bad fuel cap? If your gas cap is former or has a ruptured seal, you can lose fuel through evaporation which will result in more trips to the pump. Luckily, to replace a gas cap isn't costly. If your check engine light turns on immediately after you put gas in your 2016 Lexus GX 460, first thing you should check is to make positive the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Your 2016 Lexus GX 460 has a vacuum leak. Every Lexus GX 460 has a vacuum system that performs a humongous variety of functions.
