I would bet that anyone who has attributed problems to E10 gas was using it in equipment other than a modern car. Otherwise, they might be misdiagnosing the cause of their problems.
Ethanol-free fuel is the best thing to use in boat engines and lawnmower engines, and I used to use it in my 2003 Honda Nighthawk 750 motorcycle until I sold it (because its carbs were designed in the late 1980s), but the only way E10 causes problems on a car as new as yours is if it sits unused for long periods of time, and the ethanol is allowed to collect moisture.
I use ethanol-free fuel in my lawn equipment, but only because it often sits for months at a time unused. I only buy gas for my lawn equipment once or twice a year, so it’s worth the extra cost when you’re not burning large amounts everyday.
However, but in a car that’s a daily driver, and gets fresh fuel at least once every 2-3 weeks, it’s not worth the extra cost.
