Burning Rubber smell coming from my EZGO RXV golf cart

Hey everyone, I’m really stressed out here. My EZGO golf cart keeps giving off this burning rubber smell, and I’m clueless about what to do. It’s really affecting my rides. Has anyone faced something similar and fixed it? I’m eagerly waiting for some advice!


I totally get why you’re worried; that kind of smell can be a sign of a serious issue. I found upgrading the F&R switch to a heavy duty model fixed the problem for me.
