A break line ruptured resulting in loss of fluid and diminished breaking. Fortunately it did not result in a catastrophic loss in breaking at a critical time. The ruptured line is near the gas tank and at first appeared to be a gas leak. Upon inspection all break lines are substantially rusted and must be replaced to maintain safety. One rusty line could indicate damage or a single defective part. 100% of the lines being corroded to an unsafe level indicates substandard parts. The rear disc breaks have been a constant problem with corrosion of sliding parts resulting in calipers not moving freely. The spongy feel to the breaks was attributed to sticking of the rear calipers rather than a fluid leak. Annual lubrication and a total replacement of rear breaks has become normal practice. The poor rear breaks can lead one to not notice a slow leak of break fluid until a total loss of breaking action. The slight extra cost for corrosion resistant break parts could save lives.

Check engine light comes on in mid june 2010...referred to owners manual which was possibly due to the exhaust filter...owners manual stated specifics to clear which it did. Light appeared again and repeated owners manual procedures then scheduled appt at dealership to look at in which we received washer fluid recall at same time. Dealership repaired recall but could not duplicate reason for the "maintenance required light" issue. About a week later truck became hard to start...glow plug indicator would not work and fuel began leaking from the fuel filter. Returned vehicle to dealership in which they found the fuel filter leaking and fuel sensor cracked in which they cannot find a replacement part and are doing a worldwide search. They also told us that our truck was not equipped with a glow plug indicator which we strongly advised that it was and verified with purchasing dealership. To date, the vehicle is still at the dealership and they have not been able to repair either issue. Advised that truck cannot be operated due to the fuel leakage.

Under normal driving conditions without cause the fuel filter water-in-gas sensor bleed valve leaks fuel. This causes fuel to leak into the engine compartment. Symptoms include fuel on the ground, fuel odor, hard/longer engine cranking.
