Without any indication, front end of vehicle locked up, causing consumer to lose control of vehicle. Dealer was contacted, and stated that subframe needed to be replaced. The front differential was torqued sideways and broken apart, causing the frame to have 2 breaks, this caused the front to lock up, also prior to this consumer complained of a delay between the forward and reverse, when a bump was felt when accelerating, consumer also heard a clunk noise, dealer drained and replaced the transfer case fluid twice. The engine sputters in 4 wheel low and there is a whine noise or pulley noise from the engine. The front seat arm rest fell off. The left front daytime lamp was full of water due to the assembly being improperly sealed at the factory. The brakes pulsated and pedal felt soft, dealer stated the right rear caliper was sticking and the front and rear rotors were corroded badly, causing the brake pads to wear. The electric brake was inoperable, dealer installed a new plug, the wiring harness was badly damaged. The power windows were inoperable. The left door creaks due to front door link being loose. Consumer was informed that he was supposed to sign a waiver because of the plow being placed onto the extended cab, this was because the installation was not recommended, however the consumer was never informed of this until after the installation and the problems with the vehicle.
