We bought a Mazda CX-9 since my uncle needed one. But we didn't know while buying the car, the fuel gauge wasn't working well. Surely enough, we thought the gas filled up to 35%. The car soon halted on a bridge and we waited for help. We still don't have a solution for this and may cost a lot of money if this gets into something major.
