Has the “check engine” o r fuel system warning light appeared on your dashboard due to a fuel cap issue?

In modern cars, an improperly sealed fuel cap can trigger warning lights. Has your Oshan X7 ever shown such alerts that were later traced back to the fuel cap?

Yes, several users have seen the “Check Engine” light turn on, which was later diagnosed as a minor fuel cap seal issue. Modern cars like the Oshan X7 monitor tank pressure, and even a slightly loose o r faulty cap can trigger a warning light.
