Has anyone’s GV70 Malfunction Indicator Lamp (aka Check Engine Light) come on? Dealer “fixed” mine and the light came back on, one day later. Fuel cap appears to be seated correctly.

I have also had this issue but currently I am in the middle of waiting to take it in. I posted in the other genesis forum regarding this but basically when I purchased the vehicle there was an issue with the safety features failing. The lights came on and so did the check engine. They said it was just a battery reset issue, "fixed" it, and everything seemed fine. It has about 3500 miles on it. Every time I start it, or at least every other start up, 6 red flags come on and also the lane center doesn't work. Eventually it goes away while driving but now the check engine light is on and has not gone away in a few days. I tried getting an answer in the other forum in case it may be something like a software issue but so far no luck. I have an appointment today through the genesis app to have my car picked up and leave a loaner to take it in for the issue.

It could be something small but I checked the fuel cap and don't top up so I cant see how that is the issue, especially when the safety features have been having issues. I really hope I don't get an answer that its all good, the light just stays on cause of a glitch or whatever. I was so excited and still am to have this car but I don't want this to be a recurring issue. I hope there's a simple fix for it.

Thanks.
I mentioned the gas cap because it's a pretty common way to set off the check engine light if not seated properly.
The dealer replaced the purge valve solenoid, so I'm guessing that was throwing an error code. A day later the error light came back on.

Driving a GV80. At 1700 miles the Check Engine Light came on (steady, not flashing). We run an automotive repair facility so have access to scanning equipment. Code set was for a small evap leak. Reset the light and it is still off at 2000+ miles. This leak is strictly an EPA thing and has nothing to do with driveability or performance. Still, it should not be present. Gas cap is not an issue as 1) It is new! and 2) I filled up three days before the light came on. To add icing to the cake, the nearest Genesis dealer is 220 miles away. I will complain and will certainly have them check why the light came on (loose hose? etc.). For peace of mind you may want to go to a shop having scan equipment and just ask them to read the code.

I also have a GV80 (2.5T AWD Prestige), and have had the check engine light come on twice. It went off spontaneously after about 800 miles, but came back on recently at 5k miles and has not gone off yet. I also live far from a Genesis dealer, so have not been able to get "concierge" service. My question for you is this- How did you "reset the light"? I can probably borrow an OBD scanner, but am not familiar with how they work or if they give you the option to reset. BTW, I have tried all the obvious fixes including gas cap, and I never top-off. Thank you.

If you have an OBDII scanner there is typically a menu button that asks if you want to clear the code(s). Then it will typically ask are you sure you want to clear the code(s)?. Answer yes and it should clear the code. If the code comes back on more or less immediately it is considered a "hard" code and at that stage you should start calling the Genesis dealer for help. Check out the code number and see what it relates to. If it is an evap leak, not a big issue but it should be investigated "why". If it is O2 sensor related or cat related it could be more serious.

So, I borrowed an OBDII scanner and got the code "P0304" which is "Cylinder 4 misfire detected". I cleared the code (and the Check engine light went off), but I will get my GV80 into a dealer as soon as I can, which realistically will not be until I am back in FL where I purchased it (about 2 weeks from now). Thanks again.
