The one friend had theirs fail twice in their 2018 equinox under warranty. the dealer said that they always fail on people that run exclusively E85. after the last one was replaced they stopped running E. The other friend has a 720whp CTSV and had his fail after about 1.5years of daily driving with E. I've also talked to Speed inc in Chicago and they said the fuel system is un reliable on E85 cars. any expanded knowledge on this?

This is the 1st time I have heard of any issues related to E85 in the Gen V.


I've been running it for 3 years/30k miles with a LOT of track and AutoX time. No issues.
