We service a fleet of 70 utes for an airconditioning specialist who work on building sites, anyways the Rodeos/Collorados are always the ones that come in with the most problems, but then again they have the absolute crap thrashed out of them, probably by multiple people. (Some of those people questionable, we often come across porn mags in the car).
We also get the BF/FG eGas Falcons come in with problems like wheel bearings giving up and dead catalytic converters.
So i guess its how the car is treated.
OP must have got a lemon.
