First oil gauge. When I drive the SUV between 60 to 75 mph, the oil gauge point to zero. Dealer unable to fix it. Second. There are coolant pipe routed under vehicle without any protection. It is a great change broken by minor road hazard. My 2003 4wd sr5 Sequoia was broken at 12/19/2003. It took dealer 3 days to replace the 1 meter length pipe, because it is impossible for dealer to place the pipe at original position. This is bad design. No protection and not easy replace. I check other big SUV at market. They all use plastic shield to protect similar pipe under their SUV. I consider this is safety defect. Toyota should recall it.
