Does anyone know what this could be? 🤣
I bought my trax in nov of 24’ and the first time I filled it up with e85 the check engine light came on. (My last car was a 2011 and took e85 perfectly fine so I didn’t think twice about putting it in my trax) I checked the Chevy app and it said the problem was the fuel emission system. I took it back to the dealership and they checked over everything and told me I couldn’t put e85 in it and told me to just drive the rest of the gas out of it. Well now a few hours ago I filled my tank up with regular 87 and the check engine light came back on for the same issue. Fuel emissions system.. I’ve seen online that if air gets in your tank while you’re pumping this code can come up. I just figured I would ask on here before going to the dealership again in this economy. TYIA!
