What type of surface are you driving on?
That matters a lot. Have had a voltage for a couple years, battered and beaten, upgraded the driveshafts but that's it. Have had to resolder the motor leads a couple times since they got caught on detritus in our A O. Still all stock, lots of shoo Goo holding the body together. Probably will need tires this year. Grandson's truck actually, he beats it up, runs it into trees to do somersaults, uses the curbs at the parking lot a few doors down as ramps, loves doing donuts. Runs it on asphalt, grass, dirt.
