I just bought a 2005 Toyota Sequoia from a used car dealer in Gladstone , Oregon and they've told me that everything s good with the said vehicle. After driving it around for over 2 weeks somehow , I started hearing loud rough squeeking noise every morning during cold starts and when I took it to our local Service shop for a first time Service & Lube job our mechanic found severe rust & corrosion on the engine block, front & rear Suspension & Steering system, Exhaust system, rear driveshaft, front & rear axle differential housing. Most of the bolts holding the chasis frame and exhaust system are pretty much rusted out and when you plan to unbolt them tend to break apart . Thanks ! looking forward for your assistance.
