Brake line rusted through and lost all braking capability. Luckly it happened pulling into my driveway and not on the highway! fuel lines rusted through and leaking fuel puddling onto the ground.

(electrical) as an ongoing issue, the dashboard gauges/indicators (I.e. tach, speedometer, etc..) will sometimes not register until several minutes after the vehicle has been running (this could be for up to miles) it has not affected vehicle performance to date. (fuel/propulsion system) I have begun having issues where it goes into "reduced engine power". further diagnostic attempts have led me to believe that it is due to a faulty throttle position sensor (part of the throttle body), tac module, or app assembly (accelerator pedal). Most likely cause may be due to the throttle position sensor, as this issue has happened when the vehicle is on "cruise control". however, due to the inferior design of the throttle body unit itself, the manufacture has made it difficult or if designed to be impossible to replace just the tps, by riveting the tps to the throttle body, and may have to replace the whole throttle body. I am having the vehicle serviced for a complete diagnostic and repair, and will elaborate further upon successful repair if desired.
